Answer:

x = 98

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

x + 50 + 140 + 112 + x + x + 4 + 120 = 720, that is

3x + 426 = 720 ( subtract 426 from both sides )

3x = 294 ( divide both sides by 3 )

x = 98

A certain high school has 1,488 students. If you subtract the number of girls from boys you get 78. Let x be the number of boys and y be the number of girls.

Answers

Answer:

boys = 705

girls = 783

Step-by-step explanation:

We are to find the number of boys and girls in the school

the answer can be determined using simultaneous equation

x = boys

y = girls

y - x = 78 equation 1

y + x = 1488 equation 2

subtract equation 1 from 2

2x = 1410

x = 1410/2 = 705

Substitute for x in equation 1

y - 705 = 78

y = 705 + 78 = 783

Each morning papa notes the birds feeding on his birdfeeder. So far this month he has seen 59 blue jays, 68 black crows, 12 red robins and 1 cardinal

A. 140
B. 177
C. 75
D. 126

Answers

59+68+12+1=140

Probability of getting blue jays is : 59/140

Therefore, on 300 birds, you would get 126,43 blue jays, but you can’t have a half bird, so 126 is the answer.

Use the original price and the markup to find the retail price.
Original price: $70; Markup: 15%

Answers

The gross profit P is the difference between the cost to make a product C and the selling price or revenue R.
P = R - C
To calculate revenue R based on the cost C and the desired gross margin G, where G is in decimal form:
R = C / ( 1 - G)
The gross profit dollars P is the revenue dollars R from the sale times the gross margin G percentage, where G is in decimal form :
P = R * G
The markup percentage M, in decimal form, is gross profit P divided by cost C.
M = P/ C
M * 100 will change the decimal to a percentage.

Answer:

$80.50

Step-by-step explanation:

To find the retail price:

Find 15% of $70. 0.15 × $70 = $10.50Add the markup price to the original price. $70 + $10.50 = $80.50Final answer - $80.50

The length of a rectangle is 7 cm longer than its width.

The area of the rectangle is 120 cm².

What is the width of the rectangle?

Enter your answer in the box.

Answers

Answer:

length = 15 width = 8

Area 15x8 = 120

Step-by-step explanation:

L = length

W= width

L = W + 7 (width plus7)

Area = W x L

Area =W (W+7)

Do the distribution:

120 = W ² + 7W

Subtract 120 on both sides

W + 7W -120 = 0

Factor it

(W + 15)(W - 8) = 0

W = -15 or W = 8

8 is used for W

L = W + 7

L = 8+7=15

Length = 15

Width =8.

A circle fits in a square with sides of 12 inches. What is the approximate area of the shaded region between the square and the circle? (Use 3.14 for Pi and round to the nearest whole number.) A circle inside of a square with side lengths of 12 inches. The circle has a diameter of 12 inches. 31 inches squared 69 inches squared 106 inches squared 125 inches squared

Answers

Answer:

31 inches squared

Step-by-step explanation:

Area of shaded part = area of square - area of circle

area of square = length²

12² = 144

Area of a circle = πr²

r = radius = 12/2 = 6

(3.14) x 6² = 113.04

Area of shaded part = 144 - 113.04 = 30.96

rounding off to the nearest whole number gives 31

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?

Answers

Answer:

El valor de cada cuota fija es de $500.

Step-by-step explanation:

Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:

8000-6500=1500

1500/3=500

De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.
