Answer:
the ratio is 6.5 : 1.5
Step-by-step explanation:
it asks "what is the ratio of time spent studying in math to studying for English?"
ratio uses the ":" mark. also you put the parts like this:
first part : second part
the parts can be found by looking for the "to" as indicated bold in the question
the first part of the ratio it asks is the "time spent studying in math" in hours which is 6.5
the second part of the ratio it asks is the "time spent studying in English" in hours which is 1.5
so the answer is:
6.5 : 1.5
Answer:
Ratio of time spent studying in math to studying for English
[tex]\large \text{$=\dfrac{13}{3}$ }[/tex]
Step-by-step explanation:
What is a ratio?
We use ratios to compare two numeric quantities or quantities with the same units
Basically a ratio of one quantity x to another quantity y can be expressed in the following ways, all read as the ratio of x to y
x/ y
x to y
x : y
The most useful way of representing a ratio is by using the fractional form because it can be used in determining other quantities
In this problem you spend 6.5 hours/week studying for math and 1.5 hours/week studying for English
Since both units are the same (hours/week) we can compute the ratio as
[tex]{\dfrac{\text{Number of hours studying math}}{\text{Number of hours studying English}}\\\\= \dfrac{6.5}{1.5}\\\\[/tex]
We can simply this fraction as follows
Multiply both numerator and denominator by 10
[tex]= \dfrac{65}{15}\\\\[/tex]
Divide both sides by 5
[tex]\dfrac{65 \div 5}{15 \div 5}\\\\= \boxed{\bold{\dfrac{13}{3}\\\\}}[/tex]
This is the same as 13:3 or 13 to 3
(Be careful what is the numerator and what is the denominator.
If the question had asked for the ratio of hours studying English to hours studying Math then the ratio would be 1.5/65 = 15/65 = 3/13)
Blender uses an X, Y, and Z coordinate plane called the Euclidean geometry model in its design grid. In your own words, briefly describe the Euclidean geometry model and how you can use the model to create 3D objects.
Euclidean geometry is the study of flat and solid figures based on the axioms and theorems of the Greek mathematician Euclid (c. 300 BCE). Euclidean geometry is the plane and solid geometry that is usually taught in High schools.
How can Euclidean Geometry be used to create 3D Objects?Euclidean features are ideally suited to defining man-made settings (which are usually in 3D) and are reasonably simple for the user to give.
The incorporation of scene restrictions into the model acquisition process decreases the number of unique configurations for calibration and enables model reconstruction using small sets or even single photos despite the presence of multiple occlusions.
Another obvious use for such a technology is augmented reality. After rebuilding, real-world scene models can be merged with other reconstructed or synthetic models. This is particularly beneficial in architectural applications.
Indeed, before an architectural project is approved, its influence on the existing environment is represented using hand-drawn or computer-aided design (CAD) city models.
The process of creating such models is time-consuming and needs more previous knowledge than scene reconstruction from photos.
Furthermore, when necessary, classic architectural resources such as maps and architectural drawings are simple to include in an interactive reconstruction method.

What is rationalizing?When you rationalize an equation, you remove any surpluses from the fractions' bottom (denominator). Typically, when you are requested to rationalize or simplify an expression, it also suggests that you should do so.
To make a fraction's denominator a rational number, we rationalize any radicals or surds present. To accomplish this, we often multiply the numerator and denominator by an appropriate radical, then simplify. Divide and multiply the supplied fraction by the same square root value to rationalize the denominator. The denominator will be a rational integer in this case.

4) Jim and Edna are planting a rectangular garden with 6 rows of equal numbers of pepper
plants. Each row will be 60 feet long. They set the plants 3 feet apart and start planting at one
corner of the garden. How many plants will they need?
Answer:
120
Step-by-step explanation:
They need six rows with an equal amount of peppers on each row, luckily, everything we need to solve is problem is right in front of us.
First we divide the amounts below
How long the rows will be / How far apart the peppers will be spread.
As we can see that gives us 60 / 3, which should be 20.
Now that we’ve completed this portion we can move on.
Multiply your answer from the division, by how many rows there are.
Our answer from the division was 20, and as we can see there are six rows.
20 x 6 = 120.

Consider the inequality 7 + 4x > x − 2.
Which value(s) of x are solutions? Select all that apply
x = −3
x = 0
x = 3
x = −6
The values of x that satisfies the inequality are:
x = 0 and x = 3
Given,
The inequality = 7 + 4x > x - 2
We have to find the values of x that satisfies the inequality.
Lets check:
Check for x = -37 + 4 × -3 > -3 - 2
7 - 12 > -5
-5 > -5
Here, -5 = -5
So,
The value x = -3 will not satisfy the inequality
Check for x = 07 + 4 × 0 > 0 - 2
7 > -2
The value x = 0 satisfies the inequality
Check for x = 37 + 4 × 3 > 3 - 2
7 + 12 > 1
19 > 1
The value x = 3 satisfies the inequality
Check for x = -67 + 4 × -6 > -6 - 2
7 - 24 > -8
-17 > -8
As negative values -17 is less than -8.
So, the value x = -6 will not satisfies the inequality

Since there is no m value, it is 1/1 or simply 1. Therefore you rise 1 point for every 1 you move right.
Your graph needs to intercept the y-axis at point (0,6).

This is an assignment may someone help me but not give me the answers just explain the steps I need to take
See explanation below
Explanation:
From the question, we are told line TV is perpendicular to line US.
This means the point which they intersect has an angle of 90°.
We are also told line TV bisects STU.
For a line to bisect an angle, it means it divided the angle into two equal parts.
When line TV bisects STU, it divided it into angle STR and angle UTR
Hence, ∠STR = ∠UTR
Also line SU and line and line VT intersect to give vertical angles.
Angle R and the angle opposite it are vertical angles.
Vertical angles are equal.
The angle with 90° and the angle opposite it is also a vertical angle.
you can see from the illustration. The two angles opposite each other are equal to 90°.
Since angle on a straight line = 180°
angle R + 90° = 180°
angle R = 180-90
angle R = 90°
All the 4 angles that result from the intersection line VT and line SU are equal to 90°

The measure of the angle is 1.0 when rounded to one decimal places.
What is right triangle ?If one of the triangle's angles is 90 degrees, the triangle is said to have right angles. The triangle with a right angle is known as a right triangle because a right angle is 90 degrees. Using the Pythagorean rule, it is simple to understand how the different sides of this triangle relate to one another. The greatest side of a right angle is known as the hypotenuse, and it is opposite the right angle. In addition, the right triangles are categorized as isosceles right triangles and scalene right triangles based on the other angle values. Pythagorean triples are another name for the right triangle's side lengths, which include 3, 4, and 5.
Given that : right triangle, we're provided the hypotenuse and the leg next to. We can use the cosine ratio to determine :
Cosθ =[tex]\frac{adjacent}{hypotenuse}[/tex]
Plug in the given information
Cosθ =[tex]\frac{4}{7}[/tex]
Use the inverse cosine ratio
θ = [tex]cos^{-1} \frac{4}{7}[/tex]
Plug this into your calculator (and ensure you're solving for radians instead of degrees in the settings)
θ =0.9626
Therefore, θ = 1.0 when rounded to one decimal places.

Kendra finds the dimensions of a sticky note. She uses a meter stick to determine that the dimensions are 1.25×10−8 meters wide by 2.5×10−6 meters long. Use scientific notation to write the dimensions in millimeters
The length and the width of the sticky note in millimeters are 2.5 × 10⁻⁵ millimeters and 1.25 × 10⁻³ millimeters respectively.
The dimension of Kendra's sticky note using a meter stick are:
The width of the sticky note is 1.25 × 10⁻⁸ meters and the length of the sticky note is 2.5 × 10⁻⁶ meters.
Now we know,
1 meter = 1000 milimeters.
Therefore, the length of the sticky note in millimeters will be:
L = 2.5 × 10⁻⁸ meters
L = 2.5 × 10⁻⁸ × 1000 millimeters
L = 2.5 × 10⁻⁸ × 10³ millimeters
L = 2.5 × 10⁻⁸ ⁺ ³ millimeters
L = 2.5 × 10⁻⁵ millimeters
So, the width of the sticky note is:
W = 1.25 × 10⁻⁶ meters
W = 1.25 × 10⁻⁶ × 10³ millimeters
W = 1.25 × 10⁻³ millimeters
Hence, the dimension in millimeters is: the width and length of the sticky note is 1.25 × 10⁻³ millimeters and 2.5 × 10⁻⁵ millimeters respectively.

pls help i dont get it this is due today
Answer:
Part a: x + 17 = 52 Part b: He should guess the number 35.
Step-by-step explanation:
In the equation, x stands for the number he has to guess. He is given the clue, "17 more than the number is 52." Therefore x + 17 = 52. Another equation you could use is 52 - 17 = x. This equation would be used to solve the problem. 52 - 17 = 35

An IRRATIONAL number is a number that can't be written as a simple fraction!
What is a simple fraction? a fraction having whole numbers for the numerator and denominator. To add on that i think it also means that it can be simplified.
So we can't have a mixed number or a fraction that can't be simplified.
A. The square root of 25=5. Can we turn five into a fraction? We sure can! It's also whole, which is a good sign too.
B. The square root of 28=5.29 We can't turn B into a simplified fraction. it will be a mixed number with 6 93/100. ✅
C. The square root of 48=6.93 We also can't turn C into a simplified fraction. It will be a mixed number as well, looking like 5 29/100. ✅
D. The square root of 169=13. This is promising, it's a whole number!
