Twenty-four out of the forty pies at a bake sale are coconuts pies. What
percent of the pies are coconut?
Answer:
60%
Step-by-step explanation:
Total number of pies = 40
Number of coconut pies = 24
Percentage of coconut pies :
(Number of coconut pies / total number of pies) * 100%
(24 / 40) * 100%
0.6 * 100%
= 60%
60% of pies are coconut pies

Carefree offers two type of care packages. The food packages sell for 20$ and the game packages sell for 32$. In one day Carefree sold 25 Care packeges. the receipt for those packages totaled 602$ How many of each type of package were sold
Answer:
Number of game package = 16.5
Number of food package = 8.5
Step-by-step explanation:
LET :
Food package = a
Game package = b
a + b = 25 - - - (1)
20a + 32b = 602 - - - (2)
a = 25 - b
Put a = 25 - b into (2)
20(25 - b) + 32b = 602
500 - 20b + 32b = 602
12b = 102
b = 102 / 12
b = 8.5
a = 25 - b
a = 25 - 8.5
a = 16.5
Number of game package = 16.5
Number of food package = 8.5

A long year-end status report for work is 134 pages long. You need to print 16 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.53 each. Give your answer to the nearest cent, only for the paper you use (partial reams are OK)
Answer:
The total cost of the copies will be $ 15.14.
Step-by-step explanation:
Given that a long year-end status report for work is 134 pages long, and I need to print 16 copies for a meeting next week, to determine how much is the paper going to cost for those reports if paper is sold in reams (500 pages) for $ 3.53 each the following calculation must be performed:
(134 x 16) / 500 = X
2,144 / 500 = X
4.288 = X
500 = 100
144 = X
144 x 100/500 = X
14,400 / 500 = X
28.8 = X
100 = 3.53
28.8 = X
28.8 x 3.53 / 100 = X
101.664 / 100 = X
1.016 = X
1.016 + (3.53 x 4) = X
1.016 + 14.12 = X
15,136 = X
Therefore, the total cost of the copies will be $ 15.14.
Use the diagram to fill in the blanks
x=
m∠=
Answer:
x = 21, m∠A = 23°, the measure of angle in the right = 67°
Step-by-step explanation:
The angles of a triangle sum up to 180°.
Right angles equals to 90°.
Thus, (2x - 19)° + (3x + 4)° + 90° = 180°
=> 5x + 75 = 180
=> 5x = 105
=> x = 21
m∠A=> 2(21) -19 = 23°
the measure of angle in the right=> 3(21) + 4 = 67°

A rectangular park is 70 meters wide and 100 meters long.
Give the length and width of another rectangular park that has the same perimeter but a smaller area.
9514 1404 393
Answer:
60 m wide and 110 m long
Step-by-step explanation:
The more the shape deviates from a square, the smaller the area will be. The area can be reduced by making the park longer and narrower. The sum of length and width must remain the same for the perimeter to be unchanged.
Given park: 70 m × 100 m = 7000 m²
Smaller park: 60 m × 110 m = 6600 m² -- less area than 7000 m²

descent.
Answer:
8.05 miles
Step-by-step explanation:
If it descended 2.2 miles to 5.85 miles then that means it was at 5.85 + 2.2 miles before its descent.
5.85 + 2.2 = 8.05
Answer:
8.05 miles
Step-by-step explanation:
5.85 + 2.2 = 8.05
5.85 + 2.8 = 8.65 (not the answer, but as an example ;b

The average annual cost of the first year of owning and caring for a cat is $1,500. A sample of 81 will be used. Based on past studies, the population standard deviation is assumed known with σ = $198. What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?
Answer:
The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Sample of 81
This means that [tex]n = 81[/tex]
What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 1.96\frac{198}{\sqrt{81}}[/tex]
[tex]M = 43.12[/tex]
The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.

Bryan and Jadyn had barbeque potato chips and soda at a football party. Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium. Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium. How much sodium is in 1 oz of chips and how much is in 1 cup of soda?
Answer:
1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
x is the amount of sodium in 1oz of chips.
y is the amount of sodium in 1 cup of soda.
Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium.
This means that [tex]4x + y = 600[/tex], also [tex]y = 600 - 4x[/tex]
Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium.
This means that:
[tex]x + 4y = 300[/tex]
From the first equation, we have that [tex]y = 600 - 4x[/tex]. So
[tex]x + 4(600 - 4x) = 300[/tex]
[tex]x + 2400 - 16x = 300[/tex]
[tex]15x = 2100[/tex]
[tex]x = \frac{2100}{15}[/tex]
[tex]x = 140[/tex]
[tex]y = 600 - 4x = 600 - 4*140 = 40[/tex]
1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.
