Answer:

true

True

False

False

Step-by-step explanation:

a. The problem tells me that for every 3 parts of red paint, I have 8 parts of yellow paint. To find the ratio of 1 part of yellow paint I can write the following statement

For 8 parts of yellow paint ------------ 3 parts of red paint

        1 part of yellow paint  -------------      x

So x=\frac{1 part of yellow paint * 3 parts of red paint }{8 parts of yellow paint}

x= \frac{3}{8} parts of red paint

b, I have the following relationship

3 parts of red paint ----- 8 parts of yellow paint

If I multiply the entire expression by 3 I have left

3 * 3 parts of red paint -------- 8 * 3 parts of yellow paint

So

9 parts of red paint ---------- 24 parts of yellow paint

c.I have the same relationship

3 parts of red paint ----- 8 parts of yellow paint

If I multiply the entire expression by 1/2 I have left

3/2 parts of red paint -------- 8/2 parts of yellow paint

So

3/2 parts of red paint ---------- 4 parts of yellow paint

as 3/2 is different from 10, then the approach is false

d. observing the relation of part a,

For 3 parts of red paint ------------ 8 parts of yellow paint

      1 part of red paint   -------------      x

So x=\frac{1 part of red paint * 8 parts of yellow paint }{3 parts of red paint}

x= \frac{8}{3} parts of yellow paint  that is different than 3/8 parts of yellow paint, then the approach is false

The aorta is the largest artery in the human body. In the average adult, the aorta attains a maximum diameter of about 1.18 inch
Sholpan [36]
Well we know that 1 inch is 2.54 cm.  But how wide is .18?  Lets do .18 x 2.54 to get 0.4572.  Now lets add 2.54 + 0.4572 to get 2.9972.  This means that the maximum width of the aorta is 2.9972 cm.  Hope this helped :)

Answer:36

Step-by-step explanation:

\frac{4}{7} =\frac{48\\}{84}

for every 7 students there are 4 girls, so for every 84 there must be 48

7*12=84

4*12=48

so, in all 84 students there are 48 girls

so amount of boys=84-48=36

there are 36 boys
