Answer:
[tex]\dfrac{2}{5}\times\left(\dfrac{5}{8}\times 16\right)[/tex]
Step-by-step explanation:
In this context, "of" means "times". A product of two numbers is computed by taking one "times" the other. In short, the operations being described by the words are two uses of "times". That shows up in only one answer choice.

In 1985, the cost of clothing for a certain familiy was $620. In 1995, 10 years later, the cost of clothing for this famility was $1000. Assuming the cost increased linearly, what was the cost of this familiy's clothing in 1991
Answer:
$848
Step-by-step explanation:
Calculation for the cost of this familiy's clothing in 1991
First step is to calculate the amount that is increase per year
Increase per year= ($1000-$620)/(1995-1985)
Increase per year= 380/10
Increase per year= $38
Now let y be :38*x + $620 and let x be 6 years (1991-1985)
Second step is to calculate the cost of the clothing in 1991
y = 38*6 + 620
y=228+620
y = $848
Therefore the cost of this familiy's clothing in 1991 will be $848

5 60.20
Step-by-step explanation:
Given,
For every 5 hours money Andre gets is = $60.20
So,
For every 1 hour = $60.20 ÷ 5 = $12.04
For every 2 hours = $12.04 × 2 = $24.08
For every 3 hours = $12.04 × 3 = $36.12

which values of x make 3x+4>5(x+2) true?
x<-6
x<2
x>-6
x>2
Answer:
x<-6
Step-by-step explanation:
3x+4>5(x+2)
Distribute
3x+4 > 5x+10
Subtract 3x from each side
3x+4 -3x> 5x-3x+10
4 > 2x+10
Subtract 10 from each side
4-10 > 2x+10-10
-6 > 2x
Divide each side by 3
-6/2 > 2x/2
-3 > x
Since x must be less than -3 the only statement that would be true is x< -6

Step-by-step explanation:
The rectangle shown has a perimeter of 92 cm and the given area. Its length is 6 more than three times its width. Write and solve a system of equations to find the dimensions of the rectangle .
Answer:
Dimensions are 20cm & 26 cm .
Step-by-step explanation:
Given that the rectangle shown has a perimeter of 92 cm and the given area. Its length is 6 more than three times its width. So let
Lenght be x + 6 Breadth be x.======================================
Now According to Question ,
⇒ Perimeter = 2(l+b)
⇒ 92 cm = 2( x + x + 6 )
⇒ 92 cm = 2(2x + 6)
⇒ 92 cm = 4x + 12
⇒ 4x = ( 92 - 12) cm
⇒ 4x = 80cm
⇒ x = 80cm/4
⇒ x = 20 cm .
So , the lenght will be x + 6 = 26 cm and breadth will be x = 20 cm .
Hence the lenght of the rectangle is 26 cm and breadth is 20 cm .======================================
Answer:
The answer is that the width is equal to 10 and the length is equal to 36.

Write a polynomial f (x) that meets the given conditions. Degree 3 polynomial with integer coefficients with zeros -7i and
Answer and Step-by-step explanation:
Since it is a degree 3 polynomial, then it should have 3 solutions. But only one is given -7i which is an imaginary number. Since -7i is part of the solutions, then definitely, +7i is also part of the solutions. Since we are not given the last root, I would choose a suitable number in order to explain the process. Let us choose 1. Therefore, our roots are now:
±7i and 1.
In order to find the polynomial, we have:
x = +7i or –7i or 1, this means:
f(x) = (x – 7i)(x + 7i)(x – 1)
f(x) = [x² +7ix – 7ix – (7i)²](x – 1) = [x² – 49(–1)](x – 1) = (x² + 49)(x – 1) = x³ – x² + 49x – 49

Use the distance formula to find the perimeter. Round to the nearest tenth.
Answer:
37.6 units
Step-by-step explanation:
Perimeter = sum of all sides of the triangle
To find the sum, find the distance between each points.
✔️Distance between points (-7, 6) and (5, -4):
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = [/tex]
[tex] = \sqrt{(5 - (-7))^2 + (-4 - 6)^2} [/tex]
[tex] = \sqrt{(12)^2 + (-10)^2} [/tex]
[tex] = \sqrt{144 + 100} [/tex]
[tex] = \sqrt{244} = 15.6 units [/tex] (nearest tenth)
✔️Distance between (-7, 6) and (-7, -4):
|6 -(-4)| = 10 units
✔️Distance between (-7, -4) and (5, -4)
|-7 - 5| = 12 units
✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units

Answer:
Yes 4:3
Step-by-step explanation:
To solve this, take the the inside number and subtract in from the outside number. Look at the question very carefully for this part...
Since it says the ratio of the outside number to the inside number, take that number and see how many times it can fit into the outside number. In this case, it is 4, and than for the inside number, it is 3.
Now do the same for the other measurement and see if it has the same ratio, and if it does, that is the answer.

Amr recorded the outdoor temperature as -4 degrees Fahrenheit at 7:30 A.M. At noon, it was 22 degrees Fahrenheit. Sal said the temperature changed by 18 degrees Fahrenheit because 22 - 4 = 18
(My answer is 26 for this question.)
What was the total temperature change from 7:30 A.M until noon? Use the thermometer to help justify your solution.
Answer:
26
Step-by-step explanation:
so it changed by 26 degrees because it goes -3 -2 -1 0 and then add 22 so it is 26 i think
The total temperature change would be 26 degrees from 7:30 A.M until noon.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
We have been given that
At 7:30 A.M.,
The temperature was -4 degrees Fahrenheit
At noon,
The temperature was 22 degrees Fahrenheit
To determine the temperature change.
Here the temperature change is difference between the final temperature and initial temperature, so we have to apply the subtraction operation.
So the temperature change = 22 - (-4) = 22 + 4 = 26
Therefore, the total temperature change would be 26 degrees from 7:30 A.M until noon.
