Answer:
20160
Step-by-step explanation:
315*64 = 20160
To find the total number of cookies Kenneth bought, you multiply the number of packages (315) by the number of cookies in each package (64). This results to 20160 cookies.
Explanation:This question involves a simple multiplication operation. When Kenneth buys 315 packages of cookies and each package contains 64 cookies, to find the total number of cookies Kenneth bought, you need to multiply the number of packages by the number of cookies in each package. So, we have 315 (packages) x 64 (cookies per package).
The equation is: 315 x 64 = 20160.
Therefore, Kenneth bought a total of 20160 cookies.

Find the probability that a randomly selected student prefers dogs or is female enter answer as a fraction or decimal
To find the probability that a randomly selected student prefers dogs or is female, we need to add the probabilities of these two events. If we assume that these events are independent, we can estimate the probability by multiplying the probabilities of each event.
Explanation:To find the probability that a randomly selected student prefers dogs or is female, we need to add the probabilities of these two events. Let's say the probability of a student preferring dogs is P(D) and the probability of a student being female is P(F). Then, the probability that a student prefers dogs or is female, P(D or F), is given by P(D or F) = P(D) + P(F) - P(D and F).
Since we don't have the individual probabilities P(D) and P(F), we can't calculate the exact probability. However, if we assume that these events are independent, we can estimate the probability by multiplying the probabilities of each event.
For example, if the probability of a student preferring dogs is 0.4 and the probability of a student being female is 0.6, then the estimated probability that a randomly selected student prefers dogs or is female would be 0.4 + 0.6 = 1.

Cost to store
Percent of markup: 15%
Selling price: $85.10
Final answer:
To find the original cost before a 15% markup that results in an $85.10 selling price, divide the selling price by 1.15, which gives you $74.00.
Explanation:
The question is asking how to calculate the original cost of a product, given the selling price and the percent of markup. We can use the following formula to find the original cost (also known as the cost price):
Original Cost = Selling Price / (1 + Markup Percentage)
First, convert the percent of markup from a percentage to a decimal by dividing by 100:
15% / 100 = 0.15
Then apply the formula using the given selling price of $85.10:
Original Cost = $85.10 / (1 + 0.15)
Original Cost = $85.10 / 1.15
Original Cost = $74.00
Therefore, the original cost of the item before the 15% markup was applied is $74.00.

Rita had Rs. 32000 per month. She spent 1/3 of her money on note books and 1/4 of the remainder on stationary items. How much money is left with her?
Answer:
She has Rs 16,000 left with her
Step-by-step explanation:
In this question, we are concerned with calculating how much money is left with Rita after spending the fraction of her monthly income on the things given in the question.
Firstly, she spent 1/3 of this amount on books;
Amount spent on books is thus 32,000/3 = 10,666.67
she spent a quarter of the remainder on stationary items.
Amount spent on stationary items is 1/4 * (32,000 - 10,666.67)
= 1/4 * ( 21,333.33)
= 5,333.3325
The amount of money left with her is just simply calculated by subtracting the amount she has spent from the initial amount she had
Mathematically, that would be 32,000 - (10,666.67 + 5,333.325) = approximately Rs. 16,000

Answer: [tex]\frac{PQ}{PR} = \frac{DE}{DF} (because \frac{4}{6} =\frac{6}{9} )[/tex]
The triangles ΔPQR and ΔDEF are similar and PQ / PR = DE / DF
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔPQR
Let the second triangle be represented as ΔDEF
The measure of side PQ = 4 cm
The measure of side PR = 6 cm
And , the measure of side DE = 6 cm
The measure of side DF = 9 cm
So , the ratio of corresponding sides of similar triangles are in the same ratio
On simplifying , we get
PQ / PR = DE / DF
4/6 = 6/9
2/3 = 2/3
Hence , the triangles are similar

Two boys on bicycles start from the same place and ride in opposite directions. One ndes
one. In 3 hours, they are 27 kilometers apart. What is the rate of speed for each boy
pposite directions. One ndes twice as fast as the other
Final answer:
The rate of speed for the slower boy is 3 km/h, while the rate of speed for the faster boy is 6 km/h.
Explanation:
The rate of speed for each of the two boys can be determined by using the formula:
Rate of speed = Distance / Time
Let's assume the rate of speed of the slower boy is 'x' km/h. Therefore, the rate of speed of the faster boy is '2x' km/h, as mentioned in the question.
For the slower boy: Distance = Speed * Time. Therefore, 3x = x * 3. Solving this equation, we get x = 0 which indicates that the slower boy is not moving.
For the faster boy: Distance = Speed * Time. Therefore, 3 * 2x = 6x.
According to the question, the total distance covered by both boys is 27 km in 3 hours. So, 6x + 3 * 2x = 27. Solving this equation, we get x = 3.
Therefore, the rate of speed for the slower boy is 3 km/h and the rate of speed for the faster boy is 6 km/h.

If bc = 11 cm and tan ABC= 8 over 11 what is the area of angle ABC
Answer:
The Answer is D
Step-by-step explanation:
The area of the given triangle would be 44 cm². Hence, option (d) is true.
Used the formula for the area of a triangle,
Area of triangle = 1/2 × Base × Height
Given that,
The triangle ABC is shown in the image.
Here, BC = 11 cm
Tan ∠ABC = 8/11
Used the formula for tan x,
tan x = AC/BC
8/11 = x/11
x = 8 cm
Since, Area of triangle = 1/2 × Base × Height
Base = 8 cm
Height = 11 cm
So, we get;

Over the course of the semester, Donnie's eight test scores averaged a 76. He looked through his notebook, but he could only find seven of the tests. The test scores he has in his notebook are 71, 92, 87, 75, 64, 70, 83. What score did Donnie make on the test that is missing from his notebook?
A) 62
B) 66
C) 72
D) 77
E) 82
Donnie's average test score is 76 for all eight tests. The sum of his seven known test scores is 542. To find the missing score, subtracting this sum from the sum of all eight scores gives a missing test score of 66.
The correct answer is option B.
To find Donnie's score on the missing eighth test, we can use the fact that the average of all eight test scores is 76.
The sum of the eight test scores is 8 * 76 = 608 (since the average is calculated by summing all the scores and dividing by the number of scores).
Now, we know the sum of the seven test scores in his notebook:
71 + 92 + 87 + 75 + 64 + 70 + 83 = 542
To find the missing score, subtract the sum of the known scores from the sum of all eight scores:
608 - 542 = 66
So, Donnie's score on the missing eighth test is 66.
The correct answer is: B) 66

Hilda plans to display in a clear cube the needle Betsy Ross used to sew the first American flag. The needle will fit exactly as the diagonal of the cube.
If the side length of the clear cube is 6 inches, and the diagonal of a face of the cube is 6
inches, what is the length of the needle
Answer: the length of the needle is 8.49 inches.
Step-by-step explanation:
The diagram of the clear cube is shown in the attached photo. From the diagram, a right angle triangle ABC is formed.
BC represents the diagonal of a face of the cube.
AB represents the the side length of the clear cube.
AB = h represents the length of the needle
To determine AB, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
AB² = 6² + 6² = 72
AB = √72
AB = 8.49
