Answer:

A. 1:3

Step-by-step explanation:

The answer would be A because there are 5 candidates for president and 15 total candidates so the ratio would be 5:15. If you simplified the ratio it would be 1:3 because you divide both sides by 5.

hope this helps!!

The length of a storeroom is 4and3/5 meters.the storerooms width is 3/4 meter shorter than its length. What is the perimeter of

Vikentia [17]

P=L+W+L+W
P=2(L+W)
add 3 and 3/5 and 3/4
4+3/5+3/4
3/5 times 4/4=12/20
3/4 times 5/5=15/20
4+12/20+15/20=
4+27/20=
4+1+7/20=
5+7/20
P=2(L+W)
P=2(5+7/20)
5=100/20
5+7/20=100/20+7/20=107/20
P=2(107/20)
P=107/10
P=10 and 7/10

In math class, 4 students complete individual surveys to determine the percentage of high school teachers that have a second job

dlinn [17]

Answer:

Option D) B and C

Step-by-step explanation:

we know that

To find out the percentage of high school teachers that have a second job, divide the number of teachers that have a second job by the total number of teachers

Survey A

$\frac{28}{110}=0.2545$

Convert to percentage

$0.2545(100)=25.45\%$

Survey B

$\frac{27}{90}=0.3$

Convert to percentage

$0.3(100)=30\%$

Survey C

$\frac{21}{70}=0.3$

Convert to percentage

$0.3(100)=30\%$

Survey D

$\frac{32}{80}=0.4$

Convert to percentage

$0.4(100)=40\%$

Compare the percentages

Surveys B and C have the same percentage

therefore

Surveys B and C show proportional results, because the ratio of the number of teachers that have a second job by the total number of teachers is equal (this number is the constant of proportionality k in a proportional relationship between two variables)

Solve linear equation y=4-x y=x-4

Hatshy [7]

{ y = 4 - x
y = x - 4

Subsititute y = x - 4

[ ( x - 4 )] = 4 - x ]

isolate x for ( x - 4 ) = 4 - x

x = 4

For y = x - 4

Subsititute x = 4

y = 4 - 4

y = 0

Solution

x = 4 and y = 0

hope this helps!
