(a) 50%
(b) 17%

Explanation:

(a)
No. of seniors = 54 + 46 = 100
Total No. = 66 + 34 + 54 + 46 = 200

% of seniors = 100/200 x 100% = 1/2 x 100% = 50%

(b)
No. of juniors that do not have a job = 34
Total No. = 66 + 34 + 54 + 46 = 200

% of juniors that do not have a job = 34/200 x 100% = 17/100 x 100% = 17%

How much bigger is the area of a circle with a radius of 5 cm than a circle with a radius of 3 cm?
Deffense [45]

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

  • Circle with radius 5cm and 3 cm

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

  • How much bigger is the area of a circle.

<u>Solution:</u>

Area of circle with Radius 5cm

Area of circle = πr²

Area of circle = 22/7 × 5 × 5

Area of circle = 22/7 × 25

Area of circle = <u>78.54 </u><u>cm</u><u>²</u>

Now,

Area of circle with Radius 3 cm

Area of circle = 22/7 × 3 × 3

Area of circle = 22/7 × 9

Area of circle = <u>28.27 cm²</u>

= 78.54 - 28.27

= 50.27cm

Hence,

  • <u>Area of circle is 50.27</u><u>c</u><u>m</u><u> more than that area of circle with radius 3cm</u>

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2),
astraxan [27]

Answer:

k = 1

Step-by-step explanation:

Given

3y = 5x + k

Opposite points: (1,-2) and (-2,1)

Required

Find k

First, calculate the midpoint of the opposite points.

(x,y) = 0.5(x_1 + x_2,y_1 + y_2)

This gives:

(x,y) = 0.5(1 -2,-2 + 1)

(x,y) = 0.5(-1,-1)

Open bracket

(x,y) = (-0.5,-0.5)

The equation 3y = 5x + k becomes:

3 * -0.5 = 5 * -0.5 + k

-1.5 = -2.5 + k

Solve for k

k = 2.5-1.5

k = 1
