Answer:

50 times

Step-by-step explanation:

Total number of faces = total possible outcomes = 8

Number of 2 or 3 on spinner = required outcome = 2

Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes

P(2 or 3) = 2 / 8 = 1/ 4

From 200 ; prediction for the number of 2 or 3

1/4 * 200

= 50 times

Answer:

Step-by-step explanation:

she gave 5 oranges to her husband .

A statement that links two expressions with an equal sign is called an Equation.

It is given that

Aunt Mansah bought 100 oranges

she bought 4 oranges for 20p

1 is bought at 5p

Let x be the number of oranges she gave to her husband

The remaining oranges were sold at 5 for 40p

1 is sold at 8p

Profit = £2.60

The given data can be used to form equation and solving them will give desired answers

1 pound = 100 pence

( 100 - x) * 8 - ( 100) * 5 = 2.60 * 100

800 - 8x -500 = 260

-8x +300 = 260

8x = 40

x = 5

Therefore she gave 5 oranges to her husband .

Answer:

  the sum of the interior angles is not 360°

Step-by-step explanation:

In order for the tiles to fit as shown, the sum of their interior angles must be 360°. Each n-sided figure has an interior angle sum of ...

  180° - 360°/n

Then the sum of interior angles of 5-, 6-, and 8-sided figures will be ...

  (180° -360°/5) +(180° -360°/6) +(180° -360°/8) = 540° -360°(1/5 +1/6 +1/8)

  = 540° -360°(59/120) = 363° ≠ 360°

The angle sum is incorrect, so the tiles will overlap or leave a gap. They will not fit together perfectly.

x+40+x+x2=240

Add similar elements x+2x+x=4x

4x+40=240

Subtract 40 both sides

4x+40-40=240-40

4x =200

Divide Both sides by 4

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

From the image attached, the measurement of the roof is 5 m by 9 m on  both sides. Hence:

Area of roof = 2 (5 * 9) = 90 m²

Since solar panels cost $4.00 per square meter, therefore:

Cost of solar panels = $4.00 per square meter * 90 m² = $360

The area of the front wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) - (4 m * 4 m) = 52 m²

The area of the back wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) = 68 m²

Area of each side wall of barn = 9 m * 7 m = 63 m²

Total area of wall = 52 m² + 68 m² + (2 * 63 m²) = 246 m²

Cost of shingles = $2.50 for each square meter * 246 m² = $615

Total cost of project = $615 + $360 = $975

Answer:

the perimeter is

104/5 feet or 20 4/5 ft

Step-by-step explanation:

The perimeter is a loop that surrounds, circumscribes, nor defines a two-dimensional shape and a one length.

A park's sandbox measures [tex]20 \ \text ft[/tex] in diameter at its base.

Todd's sandbox has a [tex]4 \ \text ft[/tex] base.

Now [tex]\frac{4}{20}=\frac{1}{5}\\\\[/tex]

As a result, the scale factor for smaller sandboxes is [tex]\ \frac{1}{5}\\\\[/tex]

[tex]\to 14 \times \frac{1}{5} = 2.8\\\\\to 18 \times \frac{1}{5}= 3.6\\\\[/tex]

As a result, in Todd's sandbox, the missing lengths (in feet) are 2.8 and 3.6.

Todd's sandbox has a perimeter of [tex]4 + 2.8 + 3.6 = 10.4[/tex] feet.

Step-by-step explanation:

becuase 60×2÷10=12

The perimeter of the triangle is 188.1 m

The perimeter of a triangle can be determined by adding the three lengths of the triangle.

From the image, the coordinates of vertices of the triangle are:

(-3, 3), (-3, -2) and (3, 3)

distance between (-3, 3) and (-3, -2) is:

3-(-2) = 5  (we use y coordinates only because x are the same)

       = 50 m  (Each unit on the map represents 10 meters)

distance between (-3, 3) and (3, 3) is:

3-(-3) = 6    (we use x coordinates only because y are the same)

       = 60 m

distance between (3, 3) and (-3, -2) is:

= √(50² + 60²)     (Pythagoras)

= 78. 1 m

Perimeter = 50 + 60 + 78.1 = 188.1 m

Answer:

94.86 miles per hour

Step-by-step explanation:

The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)

The appropriate customary unit is calculated as:

1 km = 0.62 miles

153 km = x

Cross Multiply

x = 153 × 0.62 miles

94.86 miles

Therefore, the appropriate customary unit is 94.86 miles per hour

Answer:

12+n

Step-by-step explanation:

Hi!

8+n-4 = n+4

n+4 = n+4 (Can not be simplified).

(8+n)-4 = n+4

12+n = 12+n (Can not be simplified).

(8-4)+n = n+4

So the answer would be 12+n because it does not equal n+4.

Answer:

-112.5

Step-by-step explanation:

2x - 50 = -275

2x = -225

x = - 112.5

Answer:

x = -225/2 (or) -112.5

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -275 = 2x - 50

Then the value of x will be,

→ -275 = 2x - 50

→ 2x - 50 = -275

→ 2x = -275 + 50

→ 2x = -225

→ x = -225/2

→ [ x = -112.5 ]

Hence, value of x is -112.5.
