Local Calls = 36
Distance calls = 20

Ratio would be: = 36/20 = 18/10 = 9/5

In short, Your Answer would be Option A

WILL GIVE BRAINIEST Which of the following is NOT a perfect square? Question 3 options: 36 25 49 81 35 144 100

jok3333 [9.3K]

Answer:

35

Step-by-step explanation:

The way I know is because I memorized every square up to 33.

BUT that's probably not helpful to you.

Remember that every perfect square has an odd number of factors. I'm not going to list them all out, but the factors of 35 are 1, 5, 7, and 35, giving it an even number of factors. All the rest have an odd number of factors because of the property of a perfect square: a number times itself gives a perfect square, but that number only counts as 1 factor.

DEF is a dilation image of ABC. What is the scale factor?

horsena [70]

Answer:

Option (2)

Step-by-step explanation:

ΔDEF is a dilation image of ΔABC.

Rule for the dilation,

Scale factor = $\frac{\text{Length of one side of the image triangle}}{\text{Length of one side of the original triangle}}$

= $\frac{DE}{AB}$

= $\frac{4}{8}$

= $\frac{1}{2}$

Therefore, scale factor by which ΔABC is dilated is $\frac{1}{2}$ .

Option (2) will be the correct option.

Find the area and circumference of the circle below:<br> Diameter - 14 cm

MAVERICK [17]

Answer:

<em>Area : 153.86cm</em>

<em>Circumference: 43.96cm</em>

Step-by-step explanation:

<u><em>To Find:</em></u>

<em>Area __ cm</em>

<em>Circumference__ cm</em>

<u><em>Given:</em></u>

<em>Since, it given that the Diameter is 14 cm</em>

<em>Diameter which is any straight line segment that passes through the center of the circle.</em>

<em>Radius which is half of diameter</em>

<u><em>Note: </em></u>

<em>A = πr ² {Area Formula}</em>

<em>C = rd {Circumference Formula}</em>

<em>pi also known as π = 3.14 {approximately }</em>

<em>"r " means Radius</em>

<em>"d " means diameter</em>

<em>c = circumference</em>

<em>a = area</em>

<u><em>Solve:</em></u>

<em>A = πr ²</em>

<em>Since radius is half of the diameter then...</em>

<em>14/2 = 7</em>

<em>Radius = 7</em>

<em>A = 3.14(7)² { (7)² means 7 × 7 </em><u><em>Not </em></u><em>7 × 2 }</em>

<em>A = 3.14(49) { 7 × 7 = 49}</em>

<em>A = 153.86</em>

<em>C = rd </em>

<em>C = 3.14(14)</em>

<em>C = 43.96</em>

<em>Area : 153.86cm</em>

<em>Circumference: 43.96cm</em>
