Answer:

twice the number of 30 second ads = the number of 60 second ads

Step-by-step explanation:

I can not see much work done for explanation of the error, but  

let x be the ad pf 30 second

y be the ad of 60 second

so both add together will make 12 minutes, so by counting the time in seconds we will multiply 12 by 60  so we will have a equation

x +y = 12 x 60

x+y = 720 ----------1

as x is 30 second so we can say y = 2x---------- equation 2

adding value of y in equation 1

x+ 2x= 720

3x= 720

x= 720/3=  240

adding value of x in equation 2

y= 2(240)

y= 480

so from equation 1 and 2.,   x = 240     y =480

A mirror is made of two congruent parallelograms as shown in the diagram. The parallelograms have a combined area of 9 1/3 squar
Vika [28.1K]
Given:
2 parallelograms with an area of 9 1/3 yd²
height of each parallelogram is 1 1/3 yd

Area of parallelogram = base * height

We need to divide the combined area into two to get each parallelogram's base.

9 1/3 = ((9*3)+1)/3 = 28/3

28/3 ÷ 2 = 28/3 * 1/2 = 28/6 yd² or 4 4/6 yd² ⇒ 4 2/3 yd²

Area of each parallelogram is 4 2/3 yd²

4 2/3 yd² = base * 1 1/3 yd

14/3 yd² ÷ 4/3 yd = base

14/3 yd² x 3/4 yd = base
14*3 / 3*4 = base
42 / 12 = base
3 6/12 yd = base
or 3 1/2 yd = base

a) the base of each parallelogram is 3 1/2 yards
b) we can assume that the two parallelograms form a rectangle.
area of a rectangle is length times width.

length is 3 1/2 yds * 2 = 7 yds
width is 3 1/2 yds

Area of rectangle = 7 yds * 3 1/2 yds
Area = 7 yd * 7/2 yd
Area = 7*7 / 2 yd²
Area = 49 / 2 yd²
Area = 24 1/2 yd²

ipn [44]

Answer:

<em />Rate = 1.1/hr<em />

<em />

Step-by-step explanation:

Given

Start = 23

End = 16

Hours = 6\frac{1}{2}h

Required

Determine the hourly rate

First, we need to determine the ice cream sold

Ice\ Cream = 23 - 16

Ice\ Cream = 7

Next, we calculate the hourly rate:

Rate = Ice\ Cream/Hours

Rate = 7/6\frac{1}{2}h

Rate = 7/\frac{13}{2}h

Rate = 7*\frac{2}{13h}

Rate = \frac{14}{13h}

Rate = 1.07692307692/hr

<em />Rate = 1.1/hr<em> -- Approximated</em>

The question is 56 : 28 as 122 : ?
RUDIKE [14]

Answer:

56 : 28 as 122 : 61

Step-by-step explanation:

Proportion says that two ratios or fractions are equal.

As per the statement:

56 : 28 :: 122 : ?

Let x be the fourth proportion.

then;

56 : 28 :: 122 : x

by definition of proportion:

\frac{56}{28}=\frac{122}{x}

by cross multiply we have;

56x = 3,416

Divide both sides by 56 we have;

x = 61

Therefore, 56 : 28 as 122 : 61
