Answer:
kk ill save ya from the scary question
the answer is B
Because the original picture is 16 by 20...but the scaled down picture is 4 by 5. Multiply 16 and 20 respectively by 1/4, and you get the scaled version that is 4 by 5
Answer:
B
Step-by-step explanation:
A proportional relationship is represented by linear function with its linear parameter "b" equal to zero. Since b is equal to zero, the line passes through the origin and the function/relation is proportional.
To verify that we divide the y coordinate over the x coordinate we obtain a constant called k, which is the slope.
For instance:

According to this function we can easily check a proportional relationship among its points:


You could understand the ration as parts: the total number of parts was 3+7=10.
So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).
so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.
30×·15=4.50
then subtract 30 by 4.50 to get 25.50
.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
Answer:
Heres how:
Step-by-step explanation:
Example, 7.831 , here you can see that there are 3 numbers relating to a decimal. the 1 by itself is 0.1000, 3 by itself is 0.300, and the 8 by itself is 0.80 . If you add this, you get 0.831. now add the whole number, Seven. if there is more digits in the decimal, then just add another zero.
