49.5 is what percent of 33

Svet_ta [14]

49.5 over 33 and X over 100 cross multiply so multiply 33 by x you get 33x then multiply 100 by 49.5 you get 4,950 then divide 4,950 by whatever is in front of X so 33 4,950 divided by 33 equals 150%
49.5/33 X/100 49.5x100= 4,950 33* x = 33x 4,950/33=150

The question is below

Anna35 [415]

Answer:

12) A = 27

13) B = 36

14) C = 25

15) D = 30

Step-by-step explanation:

We need to complete the ratio tables

We are given:

Footballs 15 5 20 C D

Baseballs A 9 B 45 54

The table shows the ratio of footballs to baseballs.

We are given the ratio $\frac{Football}{Baseball}=\frac{5}{9}$

All other ratios will also be simplified to get $\frac{5}{9}$

12) Calculate A

Footballs = 15

Baseballs = A

Common ratio is 5/9, we need to find a number that multiplies by 5 to get 15, same number will be multiplied by denominator to get A.

We know that $\frac{5\times3}{9\times3}= \frac{15}{27}$

So, A = 27

13) Calculate B

Footballs = 20

Baseballs = B

Common ratio is 5/9, we need to find a number that multiplies by 5 to get 20, same number will be multiplied by denominator to get B.

We know that $\frac{5\times4}{9\times4}= \frac{20}{36}$

So, B = 36

14) Calculate C

Footballs = C

Baseballs = 45

Common ratio is 5/9, we need to find a number that multiplies by 9 to get 45, same number will be multiplied by numerator to get C.

We know that $\frac{5\times5}{9\times5}= \frac{25}{45}$

So, C = 25

15) Calculate D

Footballs = D

Baseballs = 54

Common ratio is 5/9, we need to find a number that multiplied by 9 to get 54, same number will be multiplied by numerator to get D.

We know that $\frac{5\times6}{9\times6}= \frac{30}{54}$

So, D = 30

a 4-meter ladder leans up a wall the foot of the ladder is 2 meters away from the wall how far up the wall will the ladder reach

svlad2 [7]

The answer is 3.46 meters

You can get the answer by using the pythagorean theorem, since the ladder and the wall form a right triangle.

c^2 = a^2 + b^2
4^2 = 2^2 + b^2
16 = 4 + b^2
12 = b^2
b = sqrt(12) or 3.46 meters
