Masja [62]

Answer:

9 to 44 is the ratio of the number of phone calls that we're from Plano to the total number of phone calls that day

Step-by-step explanation:

Given:

The total number of phone calls that was answered by secretary in a day = 88

The number of calls that were from Plano Texas = 18

To Find :

The of the number of phone calls that we're from Plano to the total number of phone calls that day

Solution:

The ratio of phone calls that we're from Plano to the total number of phone calls that day = $\frac{\text{calls from Plano texas }}{\text{Total number of calls}}$

Now lets substitute the given value,

The ratio of phone calls that we're from Plano to the total number of phone calls that day = $\frac{18}{88}$

Now reducing the fraction

=> $\frac{9}{44}$

So the ratio is 9:44

Answer:

≈ 4,22 m

Step-by-step explanation:

volume = 20000L = 20000 dm^3 = 20 m^3

diameter = 2,4m

the volume of a cilinder is π * r^2 * h (height)

20 = π * 1,2^2 * h

h = $\frac{20}{\pi * 1,44} \\$ ≈ 4,42 m

The expression, involving exponents , to represent the shaded area, in square inches, diagram. Then use that expression to calcu

mart [117]

Answer:

The shaded area is $23\ in^{2}$

Step-by-step explanation:

we know that

The shaded area is equal to the area of the large square minus the area of the two smaller squares

$A=6^{2} -(3^{2} +2^{2})\\ \\ A=(2*3)^{2} -(3^{2} +2^{2})\\ \\A=(2^{2})(3^{2}) -(3^{2} +2^{2})$

Calculate the shaded area

Remember that

$3^{2}=9\\ 2^{2}=4$

substitute

$A=(4)(9) -(9 +4)\\ \\A=36-13\\ \\A=23\ in^{2}$
