If Mr. Donahue bought 10 cookies for $8.00. At this rate, how much
would it cost for 25 cookies?
Answer:
The answer is $20.
Step-by-step explanation:
The way we find how much each cookie is is by dividing 8 by 10. We get 0.8. So now we know each cookie costs 80 cents. So, for 25 cookies, all we need to do is multiply 25 and 0.8. When multiplied, you get the answer $20.

One experiment had 10 players spinning, another experiment had 100 players spinning. Which experiment is more likely to come closer to matching its theoretical probability.
Answer: Experiment with 100 players sprinting
Step-by-step explanation:
When it comes to experiments using samples to find out the effect of a variable on an entire population by finding out the representative effect on the sample, the larger the size of the sample, the better.
A larger sample comes closer to being the actual size of the population so when this larger sample is experimented upon, the results it gives will be closer to the results that would be gotten if we experimented on the entire population. The 100 player sprinting experiment would therefore come closer to matching its theoretical probability.

Answer:
Down below is the answer.
Step-by-step explanation:
So, lets remember that the pythagreon theorm is only useable in right traingles.
The formula for the pythagreons theorm is A^2+B^2=C^2
So basically, if this is not a right triangle, the two sides(4ft^2 and 3ft^2) will be equivelent to 5ft^2.
Lets solve the pythagroens theorm and plug in our values:
4^2+3^2=5^2
Now lets use the square roots:
16+9=25
COmbine the two numbers:
25=25
This is correct!
So yes, this is a right triangle.

Simplify your answer as much as possible.
Answer:
u ≤ 2
Step-by-step explanation:
Given
- 10 ≤ - 5u
Divide both sides by - 5 , reversing the symbol as a result of dividing by a negative quantity.
2 ≥ u , then
u ≤ 2

On a scale drawing a building measures 4.5 cm tall is the scale of the drawing is 25 m per2 cm how tall is the actual building
Answer:
Actual height of the building [tex]=112.5[/tex] meters
Step-by-step explanation:
Given
Scale of the drawing
1 cm = 25 meters
This means that any 1 cm line on the map represents a length of 25 meters in actual.
The height of the building on map [tex]= 4.5[/tex] cm
Actual height of the building
[tex]= 4.5 * 25\\=112.5[/tex]meters

There are 8 roses in a vase of 14 flowers. The rest are daisies.
(a) What is the ratio of roses to daisies?
(b) What is the ratio of all flowers in the vase to daisies?
Answer:
a) 4:3
b) 7:3
Step-by-step explanation:
No. of roses= 8
No. of daisies = 6
Total no. of flowers = 14
a) Ratio of roses to daisies = No. of roses/No. of daisies
8/6
= 4/3
= 4:3
b) Ratio of all flowers to daisies = No. of all flowers/ No. of daisies
14/6
= 7/3
= 7:3
A 98% confidence interval for a proportion is found to be (0.47, 0.53). What is
the sample proportion?
A. 0.53
B. 0.51
C. 0.49
D. 0.50
Answer:
0.50
Step-by-step explanation:
The sample proportion to be found for 98% confidence interval is
D. 0.50.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval.
Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test.
In statistics, confidence is another word for probability.
Given, Sample = (0.47, 0.53).
Confidence interval = 98%.
Therefore, The sample proportion is,
= (0.47 + 0.53)/2.
= 1/2.
= 0.5.
So, The sample proportion is 0.50.

An isosceles triangle has an angle that measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply: 110 55 35 15
Answer:
35 degrees
Step-by-step explanation:
An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side
sum of angles in a triangle = 180
180 - 110 = 70
since 2 angles would be equal
70 / 2 = 35
The area of a regular polygon is 100.8cm2. The perimeter is 56cm, what is the length of the apothem
Answer:
3.6 cm
Step-by-step explanation:
Note that:
Area = 1/2 x perimeter x apothem.
To find the Apothem, the formula =
Area ÷ (1/2 × Perimeter)
Area = 100.8cm²
Perimeter = 56 cm
Hence,
Apothem =
100.8 cm² ÷ (1/2 × 56 cm)
= 100.8cm² ÷ 28cm
= 3.6 cm
Therefore, the Length of the apothem is 3.6 cm
Divide.
(2x2 + 13x + 9) = (x + 7)
I think the right question, should be like this,
= 2x² + 13x + 9/x + 7
So, the quotient is 2x - 1 and the remainder is 16, you can find answer there in attachment.

What is the length of the arc shown in red?
Answer:
≈ 18.8 cm
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
The central angle is equal to the arc subtending it, that is 60°
arc = 2πr × [tex]\frac{60}{360}[/tex]
= 2π × 18 × [tex]\frac{1}{6}[/tex]
= 36π × [tex]\frac{1}{6}[/tex]
= 6π ≈ 18.8 cm ( to 1 dec. place )
Sariya and Kate went to lunch and their total bill was $36.96. If they
left a 20% tip. How much would their total bill be?
Answer:
$ 44.352
Step-by-step explanation:
The bill of both of them was $36.96. And they gave a tip of 20%. So , the total amount paid will be ,
=> Amount = Bill + 20% of Bill
=> Amount = $36.96 + 20% of $ 36.96
=> Amount = $36.96 + 1/5 * $36.96
=> Amount = $36.96 + $7.392
=> Amount = $ 44.352
Hence the amount paid by them is $44.352.Answer:
$44.352
Step-by-step explanation:
Their bill = $36.96
Tip = 20% of $36.96
= 20/100 × 36.96
= $7.392
Hence, their total bill = $36.96 + $7.392
= $44.352
Solve: 2x-4 = -(x-6)/2
Answer:
x = 14/5
Step-by-step explanation:
2x-4= -x-6/2
multiply by 2 on both sides to get rid of the fraction
4x-8= -x-6
add both sides by 8 and both sides by x to get the constants on the right and the variables on the left
4x+x=6+8
combine like terms/simplify
5x=14
divide both sides by 5 to isolate the x
x=14/5
