The spinner is shown has eight congruent sides the spinner is spun 200 times. What is a reasonable prediction for the number of times the spinner will land on 2 or 3
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
ok ik but i need help with this i think i got it tho -275=2x -50
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.
Joseph's uncle wants to put shingles on the outside walls and solar panel the roof of his barn shown at the right. It costs $2.50 for each square meter of shingles, while solar panals cost $4.00 per square meter. How much will this project cost?
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

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)
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
Which expression is not equivalent to 8 + (n - 4)?
(8 + n) - 4
n + 4
12 + n
(8 - 4) + n
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:
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.

Three of the paths in a city park form a right triangle, as shown on the map. Each unit on the map represents 10 meters. The city plans to plant trees along these paths.
The perimeter of the triangle is 188.1 m
How to find the perimeter of the triangle?
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

three desks and a bookcase together weigh 157 lb. The bookcase 34 lb. How much does each desk way. Write and solve an equation.
Answer:
Step-by-step explanation:
Let "d" represent desks:
157 = 3d + 34
You would then subtract 34 from 157:
123 = 3d
You would then divide 123 by 3, since you are now finding the weight of 3 desks:
123
----- = d
3
Therefore, d = 41 lb.

A park has a triangular sandbox. Todd wants to create a smaller sandbox at his backyard having the same angles as the park sandbox. Drawings of both sandboxes are shown. 18 ft 20 Park Sandbox 8+ Todd's Sandbox What is the perimeter, in feet (ft), of Todd's sandbox?
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.
Perimeter Calculation: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.

Answer:
250
Step-by-step explanation:
she gave 5 oranges to her husband .
What is an Equation ?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
