Answer:
for the first picture, she cleans 30 windows
the second picture is 52/100 :)
Answer:
It's B for the first one.
For the second one, it is C
Step-by-step explanation:
30 * 0.3 = 9
So 30% of 30 is 9. She did 9 windows.
0.52 = 52/100
It's 52/100 because 0.52 = 52%. 52% then equals 52/100.
52/100 = 13/25
So the answer is 13/25

what will be the new coordinate of vertex b if the triangle is dilated with a center at the origin by a scale factor of 1/3
Answer:
6 , 3
Step-by-step explanation:
your welcome
The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2) and this can be determined by using the given data.
Given :
Dilation Factor = 1/3Points - A(-2,2), B(3,6), and C(1,-2)After the dilation of 1/3 the coordinate of the triangle becomes:
[tex]\rm A(-2,2) \to A'(-2\times \dfrac{1}{3},2\times \dfrac{1}{3}) = A'\left(\dfrac{-2}{3},\dfrac{2}{3}\right)[/tex]
[tex]\rm B(3,6) \to B'(3\times \dfrac{1}{3},6\times \dfrac{1}{3}) = B'\left(1,2)[/tex]
[tex]\rm C(1,-2) \to C'(1\times \dfrac{1}{3},-2\times \dfrac{1}{3}) = C'\left(\dfrac{1}{3},\dfrac{-2}{3}\right)[/tex]
The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2).

A car travels 2 5/8
miles in 3 1/2
minutes at a constant speed. Which equation represents the distance, d, that the car travels in m minutes?
Ad = 0.75m
B. d=14 m
C. d = 3.5m
D. d = 2.625m
Answer:
A. d = 0.75m.
Step-by-step explanation:
If, for 3 1/2 minutes (3.5 minutes) the car travels 2 5/8 miles (2.625 miles),
Then in m minutes the car will travel d miles
d = (2.625*m)÷ 3.5
d = 0.75m
