Answer: 4 inches by 10 inches
Step-by-step explanation:
The area of a rectangle can be written as b*h, while perimeter is equal to (2b +2h).
A = b*h = 40
P = 2b + 2h = 28
P = 2b + 2h
28 = 2b + 2h
28 = 2(b+h)
14 = b + h
What two numbers add to 14 and multiply to 40?
4 * 10 = 40
4 + 10 = 14
Answer:
10 and 4
Step-by-step explanation:
so in the thing p=m/v to find m would you times v by p?
M = mass
p = density
v = volume
Yes, to find m it would be m = pv.
To find v that would be m/p.
Scott took 7 math tests in one semester.
His scores on the tests were: 89, 73, 84, 91, 87, 77, 94
What was his mean test score.
Answer:
Answer:
His mean test score was 85.
Step-by-step explanation:
The mean of something is the average of a data set.
To find the average, we find the sum of all the scores, and divide it by the number of scores there are.
Let's find the sum:
89+73+84+91+87+77+94
595
There are 7 total scores.
595/7=85
Answer:
85
Step-by-step explanation:
Add 89+73+84+91+87+77+94=595/7=85

Answer:
x = 20
y = 10
Step-by-step explanation:
Since we have a right triangle then:
sin(60) = 10√3/x ⇒ x = 10√(3)÷sin(60) = 20
cos(60) = y/20 ⇒ y = 20×cos(60) = 10
Answer:
Option B)
The value of x is 20 and y is 10
Step-by-step explanation:
Here, in a given right triangle
ΔABC, m∠B = 90°
Now,
tanθ = opposite ÷ adjacent
tan 60° = 10√3 ÷ y
√3 = 10√3 ÷ y
y = 10√3 ÷ √3
y = 10
Now,
sinθ = opposite ÷ hypotenuse
sin 60° = 10√3 ÷ x
√3 ÷ 2 = 10√3 ÷ x
√3 × x = 10√3 × 2
x = 20√3 ÷ √3
x = 20
Thus, The value of x is 20 and y is 10

Answer:
square root of 68, or 8.24
Step-by-step explanation:
You have to use the Pythagorean theorem. 2 and 8 will both be squared. 2 squared is 4, and 8 squared is 64. Add those up and you get 68. Since the Pythagorean theorem states that a squared + b squared = c squared, you have to square C.
alice is building a fenced in pen in her backyard for her dog,as shown. write an expression that represents the total amount of fencing she will need in feet. if the longer dimensions of the rectangle is 27 feet how many feet of fencing does Alice need?
Answer:
p = 2 * w + 54
Step-by-step explanation:
To know the number of feet Alice needs, you must calculate the perimeter, the perimeter of a rectangle would be the sum of its sides, that is, twice the width and twice the length.
This time they give us the length that is equal to 27 feet, therefore, the equation of the perimeter would be:
p = 2 * w + 2 * l
p = 2 * w + 2 * 27
p = 2 * w + 54
Therefore, to know exactly what Alice needs, you need to know the value of the width and shortest side.

How many ways can you order your favorite 3 desserts from a menu of 8?
6720

40,320
336
Answer:
336
Step-by-step explanation:
The total number of ways to order your favorite 3 desserts from a menu of 8 is 336, the correct option is D.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of
[tex]D ^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
We are given that;
The number of ways to order 3 desserts from a menu of 8 is given by the combination formula:
C(8,3) = 8! / (3! * (8-3)!) = 56
This means there are 56 different ways to choose 3 desserts from the menu of 8. Once the desserts are chosen, there are 3! = 6 ways to order them.
For 3 desserts from a menu of 8
56 * 6 = 336
Therefore, by combinations and permutations answer will be 336.

Accelerated students: Answer the above and make a line plot of the data.
Answer:
Mean: 88.5
Median:90
Mode:98
Step-by-step explanation:
For mean, what you need to do is add all of those numbers up and divide them by how many you have. So once you add up all those numbers, divide them by six because there are 6 numbers. For the median, order the numbers from smallest to biggest and cross off every one until you get left with the number in the middle. If there is an even number of numbers and there are two middle ones, add them together and divide them by 2. For mode, it’s the one with the most. Please don’t hesitate to write back if you need anything else or any of the answers are incorrect. Have an amazing day!!

Answer:
A) 5x-7y=42
Step-by-step explanation:
We know that 5 x 7 = 35 then add 7 = 42
We divide 5 and 7 by 5/7
5/ 5/7 = 0.1
7/ 5/7 = 0.2
We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5
We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.
We then use 7 for y and keep 5 for x.

The addition is one of the four fundamental mathematical operations. The correct option is B.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Given that the price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days. Therefore, The change in the price of the stock is,
Change in the price = (-$4 × 3 days) + (+$2 × 4 days)
= -$12 + $8
