Step-by-step explanation:
Raj is 53.56 inches tall. He is 1.3 times as tall as his younger sister. How tall is Raj's younger sister
Answer:
41.2 inches tall
Step-by-step explanation:
53.56 / 1.3 = 41.2
Step-by-step explanation:
Let Raj's sister's height be x
53.56= 1.3x
= 53.56/1.3=x
= 41.2=x

Answer:
MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8

The graph of the invertible function f is shown on the grid below
What is the value of f^-1(6)
Given:
The graph of an invertible function [tex]f[/tex] is given.
To find:
The value of [tex]f^{-1}(-3)[/tex].
Solution:
We know that, if the graph of an invertible function [tex]f[/tex] passes through the point (a,b), then the inverse function [tex]f^{-1}[/tex] passes through the point (b,a).
From the given graph it is clear that the graph of the function [tex]f[/tex] passes through the points [tex](-5,-3)[/tex].
So, the inverse function [tex]f^{-1}[/tex] must be passes through the point [tex](-3,-5)[/tex].
Therefore, the value of inverse function is [tex]-5[/tex] at [tex]x=-3[/tex]. So, the value of [tex]f^{-1}(-3)[/tex] is [tex]-5[/tex].

A student earns an 80% on their science test. If she got 20 questions correct, how many total were on the test?
Answer:
25 questions
Step-by-step explanation:
20 questions = 80% If she got 80%, that means she got 20 questions correct.
5 questions = 20% Here, we simply just divide by 4 to give us 20%.
25 questions = 100% The total of the test would of course equal 100%, so we just multiply by 5 to give the total questions.
I hope this helps you!! ^-^
Answer:
25.
Step-by-step explanation:
By proportion it is
(100/80) * 20
= 1.25 * 20
= 25.

A. The data represent an exponential function because there is a
common ratio of 4.
B. The data represent a linear function because there is a common
difference of 9
C. The data represent an exponential function because there is a
5
common ratio of -
D. The data represent a linear function because there is a common
difference of -9.
Answer:-8
Step-by-step explanation:
The data represent a linear function because there is a common difference of -9.
What is a linear function?The term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
Given, the table, we need to see whether the data in the table represent a linear function or an exponential function.
From the table, we have the following highlight :-
As the values of x increase by 1, the values of y decrease by 9
A decrement of 9, means -9
This means that, the common difference is -9.
Only a linear function can have a common difference.
Hence, the true statement is (b)

Is y proportional to x and y? Why or why not
Answer:
X is directly proportional to y means the value of x is dependent on the value of y. y may not be dependent on x in this case.
Y is directly proportional to x means the value of y is dependent on the value of x. Same as above, in this case, the value of x may not depend on y.

Gabriel took a bath on Monday evening. He measured the water and found that he used 1,235l of water. On Tuesday, he took a shower and only used 478 litres of water. What was the difference in volumes? How much water did he used in total?
Answer:a)757liters
b)1, 713 litres
Step-by-step explanation:
Amount of water used on Monday =1,235l
Amount of water used on Tuesday =478liters
Difference in volumes for the two days
=1,235l -478l
=757liters.
Total amount of water used up in Total
1,235litres +478liters
=. 1, 713 litres.

how to count slope on linear equasions
Answer:Do rise over run, maybe watch a tutorial on it, pretty simple method
Answer:
there are only three simple steps (:
Step-by-step explanation:
1. identify the two points on the line
2. select one to be (x1, y,1) (rise over run) and the other to be (x2, y2)
3. use slope equation to calculate your slope (m=rise/run= y2-y2/x2-x1)
in the equation of a straight line (equation written y=mx+b) the slope is m and b is the y intercept. (where the line crosses the y axis) this is the slope intercept form)

Angle B = 54°
Step-by-step explanation:
complimentary means they add up to 90
54 + 36 (angle A) = 90
also x= 51
Answer:
m∠B = 54°
Step-by-step explanation:
Note: Complementary angles add up to 90°
Thus, m∠A and m∠B must add up to 90.
We can then write this equation.
x - 15 + x + 3 = 90
Simplify.
2x - 12 = 80
Add 12 to both sides.
2x = 102
x = 51
m∠B is (x + 3) , so m∠B = 51+ 3 = 54°
Just in case, let's double check. Plug 39 for x into m∠A to get
m∠A = 51 - 15 = 36
Then, plug the angle measures in.
36 + 54 = 90
90 = 90
Thus, the answer is correct.
I hope this helps! Feel free to ask any questions! :)
Find the square roots of the two factors of 36 and multiply them.
X, Y and Z are three points on a map. Y is 43km and on a bearing of 041° from X. Z is 67km and on a bearing of 117° from X. Calculate the distance between Y and Z rounded to 1 DP
Answer:
70.3km
Step-by-step explanation:
When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x
i.e 117-41 = 76
Using cosine rule,
YZ²= 43² + 67² - 2 x 43 x 67
cos76
YZ= √4944
= 70.3

Amy wrote a 10 sided die numbered one through 10 what is the probability that she will hold a number divisible by four
Answer:
2/10 or 20%
Step-by-step explanation:
Because 4 and 8 are the only numbers 1-10 that are divisible by four.
This would give Amy a 2/10 chance of rolling a number divisible by 4.
To turn 2/10 into a percent, the denominator has to be 100 so if you multiply 10 by 10 you will get 100, you will also have to multiply 2 by 10 to get 20 and you will get 20/100
20/100 is equal to 20%
Therefore your answer would be 2/10 or 20%
