Answer:
Answer is 18 , because you add 15 and 3 which makes 18 so your answrer is x=18
Step-by-step explanation:
really hope this helped , please give me brainlest :) .
AC = 15 x 1.8 = 27
So x = 17
(this is for ABE similar to ACD)
15+3=18
18/15= 1.2
scale factor= 1.2
10x1.2= 12
12-10=2
x=2
(this is for AEB similar to ADC)

How is 1 over 9 a rational number?
Answers
Answer:
Because 1/9 is a fraction with integers meaning it is a fraction with whole numbers.
Step-by-step explanation:
Any number that can be written as a fraction with integers is called a rational number. For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)

1.80 in^3
1.0 fluid ounces^3
Step-by-step explanation:
volume of a cone = 1/3 πr²h
π = 3.14
r = 2.2 / 2 = 1.1
h = the value of h can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
1.8² = 1.1² + b²
3.24 = 1.21 + b²
3.24 - 1.21 = b²
2.03
b = √2.03 = 1.42
Volume = 1/3 x 3.14 x 1.21 x 1.42 = 1.80 in^3
1.80 x 0.554 = 1.0 fluid ounces^3

1. Express each as a unit rate.
a) A car travelled 150 km in 3 hour. Show your work.
Answers
Given:
A car traveled 150 km in 3 hour.
To find:
The unit rate.
Solution:
We have,
Distance = 150 km
Time = 3 hours.
In this case speed is the unit rate.
[tex]Speed=\dfrac{Distance}{Time}[/tex]
Substituting the given values, we get
[tex]Speed=\dfrac{150\text{ km}}{3\text{ hr}}[/tex]
[tex]Speed=50\text{ km/h}[/tex]
Therefore, the unit rate is 50 km/h.
Triangle A is reflected in the x-axis to give B.
Triangle B is reflected in the y-axis to give C.
Describe fully the single transformation that maps A onto C.
PLZ HELP
Answers
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y). If a point B(x, y) is reflected over the y axis, the new point is at A'(-x, y).
Triangle A has vertex at (-4, -2), (-4, -5) and (-2, -5). If triangle A is reflected in the x axis to give triangle B, the vertex of triangle B is (-4, 2), (-4, 5) and (-2, 5).
If triangle B is reflected in the y axis to give triangle C, the vertex of triangle C is at (4, 2), (4, 5) and (2, 5). Hence the transformation is:
(x, y) ⇒ (-x, -y)

Answer:
The answer is either (3) or (4) because drawing a line of best fit and finding its gradient is going to give you a negative answer
Answer:
-0.93
Step-by-step explanation:
As mentioned by Nicolas above, the line of best fit should give a negative coefficient because as x increases, y decreases.
Furthermore, since the lines do not make a perfect line, it cannot be the perfect fit, or a correlation of -1.00.
So we choose a negative answer but not -1.00 as explained previously. That lease the only choice of -0.93, by elimination without doing any calculations.

C. Chad is incorrect because intersecting lines are sometimes perpendicular.
D. Chad is correct because intersecting lines are sometimes perpendicular.

Answer:
C. Chad is incorrect because intersecting lines are sometimes perpendicular.
Step-by-step explanation:
SOMETIMES perpendicular (90 degree angle, aka right angle) not always.
Chad is incorrect because intersecting lines are sometimes perpendicular.
What are perpendicular lines?If the angle between two lines is 90 degrees, lines are called perpendicular lines.
If two lines intersect each other, it is not necessary that they will intersect at 90°.
Sometimes they can intersect at 90° and sometimes not.
So, Chad is incorrect because intersecting lines are sometimes perpendicular.
Hence, Chad is incorrect because intersecting lines are sometimes perpendicular.

Tyrone is converting StartFraction 45 Over 50 EndFraction to a percent. Which method should he use to find the percent?
Answers
Answer:
Multiply the numerator and the denominator of the fraction by 2.
Step-by-step explanation:
Here are the options :
Divide the numerator and denominator of the fraction by 2.
Subtract 40 from the numerator and denominator of the fraction.
Multiply the numerator and the denominator of the fraction by 2.
Add 50 to the numerator and denominator of the fraction.
(45 x 2) / (50 x 2) = 90/100
Multiply 90/100 by 100 = 90%
the same answer would be gotten if 45/50 is multiplied by 100
45/50 x 100 = 90%
