Perimeter is 30.A triangle's perimeter is measured in the same unit as its side lengths.
What is the perimeter of the triangle?Additionally, a triangle's perimeter and side lengths are measured in the same unit.If the lengths of its sides are measured in a different unit, first convert them to that unit.
Perimeter of a triangle = sum of all three sides.
Since it's equilateral, just solve for x with any of the 2 sides being equal
2x + 4 = 3x + 1
Subtract 1 from both sides
2x + 3 = 3x
Subtract 2x from both sides
3 = x
Perimeter is 10 + 10 + 10 = 30

Rose chin deposited $900 in a new savings account. The amount for $1.00 compounded daily the account earns after 12 years at 5.25% interest is 1.878. Calculate the compound interest earned after 12 years.
The answer to this Question based on Compound Interest is 1690.2$
What is Compound Interest?
Compound interest is a type of interest that is calculated not only on the initial principal but also on the accumulated interest of previous periods. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal plus previously accumulated interest. It is the concept of earning interest on interest, which causes the total balance to grow at a faster rate than simple interest. Compound interest is often referred to as the eighth wonder of the world, as it is a powerful financial concept that can yield impressive results over a long period.
Initial money deposited = 900$
1$ turns into 1.878$ after 12 years of Compound Interest
hence by basic manipulation we can do like
900$ turns into 900 multiplied by 1.878 which comes out to b 1690$
Hence after 12 years final amount will be 1690$

The statement describes values of x and y such that x/y could be an irrational number is B. The value of x is the square root of an integer, and the value of y is an integer greater than zero.
How to illustrate the irrational number?The square root of an integer for x and a positive integer greater than zero for y are described in the statement as values of x and y that could be irrational numbers.
We have provided x and y values that could be irrational numbers. Any real number that cannot be expressed as the quotient of two integers is considered an irrational number. Positive whole numbers are not considered negative integers, nor are negative integers, or numbers below zero.
Consequently, we can say that A, C, or D do not demonstrate the irrational numbers since they are all expressed as integers.

Find the total surface area of this triangular prism 13cm 5cm 12cm 9cm 15cm 20cm.
The surface area of the triangular prism is 924 cm².
What is the triangular prism?
When a prism has three rectangular sides and two triangular bases, the prism is said to be triangular. A pentahedron, that is.
Volume is calculated using the formula volume = 0.5 * b * h * length, where b is the triangle's base length, h is its height, and length is the prism length.
Area is defined as length * (a + b + c) + (2 * base area), where a, b, and c are the triangle's sides and base area is the triangle's base area.
The surface area is equal to the area of the two triangles + area of the three rectangles.
Area of two triangles:
12 × (9+5) × 1/2
= 84
84(2) = 168
Area of the three rectangles:
15 × 20 + 13 × 20 + 14 × 20
= 840
840 + 84

Andrew just started a running plan where he runs 12 miles the first week and then increases the number of miles he runs by 5% each week. If he keeps up this plan for 10 weeks, how many total miles would Andrew have run, to the nearest whole number?
Answer:
18 miles.
Step-by-step explanation:
You start with 12 miles and then you first need to figure out what 5% of that is by doing the equation x/12 = 5/100 and you will then get .6. Then you multiply that number by 10 (one for each week) getting 6. Then you add the 6 to your starting total to get 18.
Jody has 3 red marbles, 6 blue marbles, and 9 yellow marbles. What is the ratio of red marbles to blue marbles?
Answer: The ratio of red marbles to blue marbles is 3:6. This can be written as a fraction as 3/6, which simplifies to 1/2.
Step-by-step explanation:
To find the ratio of two quantities, you can divide the number of one type of item by the number of another type of item. In this case, the ratio of red marbles to blue marbles is 3 marbles / 6 marbles, which simplifies to 1/2.
It's important to note that a ratio is not the same thing as a percentage or a fraction. A ratio is a comparison of two quantities, while a percentage is a measure of a quantity relative to the total amount and a fraction is a division of one number by another.
Calculate the size of the following marked angles:
v, w, x and y.
The measures of the angles are v = 80°, y = 100°, w = 45°, and x = 55°.
What is a cyclic quadrilateral?An inscribed four-sided polygon in a circle is known as a cyclic quadrilateral. With the specified side lengths, it has the largest area feasible.
Given the quadrilateral inside a circle.
The angle v is given by:
45° +v + 55°=180°
v + 100° = 180°
v = 180° - 100°
v = 80°
Since the quadrilateral is cyclic, the sum of its opposite angle is 180°.
Therefore,
y + v = 180°
y + 80° = 180°
y = 100°
Using the property of cyclic quadrilateral, it follows:
w = 45° and x = 55°
Hence, the measures of the angles are v = 80°, y = 100°, w = 45°, and x = 55°.

What is slope?A line's steepness and direction are measured by the line's slope.
Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line can be used to calculate the slope of any line.
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-
P1 = (x1, y1) and P2 = (x2, y2)

why does the normal distribution have an importance in statistics of wether or not iut appears in nature
The normal distribution have an importance in statistics of whether or not out appears in nature, because it fits several natural phenomena.
For exa. measurement error, heights, IQ scores, and physical activity measures all follow the normal distribution.
In this question we need to describe why does the normal distribution have an importance in statistics of whether or not out appears in nature.
We know that if we plot the probability distribution and it forms a bell-shaped curve. If the mean, mode, and median of the sample are equal then the variable has normal distribution.
A normal distribution is dependent on two parameters of the data set: mean and the standard deviation of the sample.
This characteristic of the normal distribution makes it extremely simple.
Also, the normal distribution is important because of the Central limit theorem.
It makes math easy - like calculating moments, correlations between variables, and other calculations that are domain specific.

Temperatures in °F can be converted in °C using the formula
C=5(F-32)/9
Make F the subject of the formula
Give your answer in the form aC+b/c where a,b and c are all positive integers
Answer:
Step-by-step explanation:
To make F the subject of the formula, you need to solve for F in the equation C = 5(F-32)/9.
You can do this by first multiplying both sides of the equation by 9 to get rid of the fraction:
C * 9 = 5(F-32)
Then, you can distribute the 5 on the right side of the equation:
C * 9 = 5F - 160
Then, you can add 160 to both sides of the equation to isolate the F term:
C * 9 + 160 = 5F
Finally, you can divide both sides of the equation by 5 to solve for F:
F = (C * 9 + 160)/5
This gives you the final form of the equation:
F = (9C + 160)/5
In this form, F is the subject of the formula. a = 9, b = 160, and c = 5 are all positive integers.
Answer:
[tex]F=\dfrac{9C+160}{5}[/tex]
Step-by-step explanation:
Given equation:
[tex]C=\dfrac{5(F-32)}{9}[/tex]
Multiply both sides by 9:
[tex]\implies 9C=5(F-32)[/tex]
Divide both sides by 5:
[tex]\implies \dfrac{9C}{5}=F-32[/tex]
Add 32 to both sides:
[tex]\implies \dfrac{9C}{5}+32=F[/tex]
[tex]\implies F=\dfrac{9C}{5}+32[/tex]
Rewrite 32 as a fraction with denominator 5:
