Step-by-step explanation:
A 24-ounce can of mixed nuts contains 50% peanuts, 0.20 almonds, 1/10 cashews, and 0.20 hazelnuts. Which of the following represents the total amount of almonds and hazelnuts in the can?
Answers
Answer:
9.6 ounces
Step-by-step explanation:
Step 1
We find the amount of ounces of Almonds
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are almonds.
Hence,
The amount of almonds = 0.20 × 24 ounces
= 4.8 ounces
Step 2
We find the amount of ounces of hazelnuts
Total amount of nuts in the container = 24 ounces
0.20 of the nuts are hazelnuts.
Hence,
The amount of hazelnuts = 0.20 × 24 ounces
= 4.8 ounces
Step 3
Therefore, the total amount of almonds and hazelnuts in the can is
4.8 ounces + 4.8 ounces
= 9.6 ounces

Hans invests $550 at a rate of x% per year compound interest. At the end of 10 years, the value of the investment is $638.30, correct to the nearest cent.
Find the value of x.
Answers
Answer:
1.5%.
Step-by-step explanation:
x per cent is written as 0.01x as a decimal fraction.
638.30 = 550(1 + 0.01x)^10
(1 + 0.01x)^10 = 638.30/550
Taking logarithms:
10 ln (1 + 0.01x) = ln ( 638.30/550)
ln (1 + 0.01x) = ln ( 638.30/550)/ 10
ln(1 + 0.01x) = 0.014889
Converting the logs:-
1 + 0.01x = e^0.014889 = 1.015
0.01x = 1 - 1.015
0.01x = 0.015
x = 0.015/ 0.01
= 1.5.
For a certain population of sea urchins, 16% are longer than 8 inches. A random sample of 75 sea urchins will be selected. What is the standard deviation of the sampling distribution of the sample proportion of sea urchins longer than 8 inches for samples of size 75?
Answers
Answer:
0.042
Step-by-step explanation:
Given :
p = 16% = 0.16
q = 1 - p = 1 - 0.16 = 0.84
Sample size, n = 75
The standard deviation of sampling distribution :
√(pq)/n
√(0.16 * 0.84) / 75
√0.1344 / 75
√0.001792
Standard deviation of sampling distribution = 0.0423320

you install 412 feet of fencing along the perimeter of a rectangular yard. the width of the yard is 102 feet. what is the length of the yard?
Answers
Answer:
Length = x feet = 104 feet
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = x feet
Width = 102 feet
Perimeter of a rectangle = 412 feet
Perimeter of a rectangle = 2(length + width)
412 = 2(x + 102)
412 = 2x + 204
412 - 204 = 2x
208 = 2x
x = 208/2
x = 104 feet

Answer:
No, it is not.
Step-by-step explanation:
The reason is that if you simplified 4/8, you will get 1/2. When you simplified 8/10, you will get 4/5. 1/2 and 4/5 aren't the same number or equivalent to each other so the answer will be no.

Step-by-step explanation:
The above image shows two triangles. if we look at the top triangle, we notice it's two sides are equal (16 and 16). We therefore have an isosceles right triangle.
looking the second triangle, we notice that one side is 39, the other 40. Since these are the two sides joined at the point of intersection for the two images, and since 39 does not equal 40, the second triangle cannot be an isosceles right triangle. We conclude that the two triangles are not similar.
John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer. John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit. Caleb decided to go to Club4Fitness, which just charges $8 per visit. After how many visits have John and Caleb spent the same amount of money, and how much money did they spend?
Answers
Answer:
10 visits
Step-by-step explanation:
John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.
Let the number of visits be represented as: x
For John
John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.
The equation = $30 + $5 × x
= 30 + 5x
For Caleb
Caleb decided to go to Club4Fitness, which just charges $8 per visit.
The Equation = $8 × x
= 8x
We equate both equations to each other
30 + 5x = 8x
Collect like terms
30 = 8x - 5x
30 = 3x
x = 30/3
x = 10
Therefore, John and Caleb would spent the same amount of money after 10 visits.
