Answer:

Kayla

Step-by-step explanation:

To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework

Kayla: 3.2 ÷ 4 = 0.8

Karen: 5 ÷ 6 = 0.833

Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.

Answer:

49 1/8

Step-by-step explanation:

92 8/9 - 43 5/6

Subtract the whole numbers

92 - 43 = 49

Find the LCD of 8/9 and 5/6 and rewrite to solve with the equivalent fractions.

16/18 − 15/18= 1/18

Combining the whole and fraction parts.

49 + 1/18 = 49 1/18

Answer:

49 1/18

Step-by-step explanation:

First, we can start off by rewriting our equation with parts separated.

92 - 43 + 8/9 - 5/6

Solve the whole numbers

92 - 43 = 49

Solve the fractions using LCD

8/9 - 5/6 = 1/18

Combine the whole and fractions

Polynomials are expressions. The factorized form of the polynomial is 5x⁴-80 is 5(x⁴-16).

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

In order to factorize the given polynomial, we need to take the common terms out of the polynomial. Therefore, the polynomial can be written as

[tex]5x^4 - 80\\\\[/tex]

If we look at the polynomial the common term 5 can be taken out from both the terms, therefore,

[tex]5x^4 - 80\\\\= 5(x^4-16)[/tex]

Hence, the factorized form of the polynomial is 5x⁴-80 is 5(x⁴-16).

Answer:

Let's set up an equation;

12/100 * x = 16.5

where 12/100 is 12%

x is the number of the 12%

that would equal 16.5

So solve for x;

12/100 * x = 16.5

12/100x = 16.5

0.12x = 16.5

/0.12    /0.12

Answer:

8 hours

Step-by-step explanation:

First, you must subtract $32 from $125. You end up with $93.

Usually, you would do 93 divided by 12, but 93 is not a multiple of 12.

96, which is 12 times 8, is the closest to 93, so 8 hours is the correct answer.

Answer:

i believe 10/10 is just 1 so i think 3

Answer:

I'm not so sure, but I think it's 3.

Step-by-step explanation:

10/10 is equal to one whole, 1.

So you rewrite the equation:

2 + 1 = 3.

For the lines to be parallel the two angles need to be equal to each other:

128-x = x

Add 1x to both sides

128 = 2x

Divide both sides by 2:

X = 128/2

X = 64

Answer: x = 64

The system of equations for this problem is defined as follows:

From the first equation, we have that:

y = 21 - 3x.

The second equation is given as follows:

2x + 2y = 24.

Simplifying the equation, we have that:

x + y = 12.

Replacing the first equation, we have that the value of x is obtained as follows:

x + 21 - 3x = 12

2x = 9

x = 4.5.

Then the value of y is of:

4.5 + y = 12

y = 7.5.

Answer:

In the system of equations, x represents the weight in ounces of each bar of soup.

In the system of equations, y represents the weight in ounces of each bottle of lotion.

The ordered pair that is a solution to the system of equations is given as follows: (4.5, 7.5).

Step-by-step explanation:

12% is the percent decrease

95,920 is 88% of 109,000.
x/100 = 95,920/109,000

95,920 x 100 = 9,592,000

9,592,000 / 109,000 = 88

100 - 88 = 12

Since it is 88% of it, it decreased by 12%

Answer:

12%decrese

Answer:

6 large wreaths

(and 3 small wreaths)

Step-by-step explanation:

Let x = number of small wreaths made

Let y = number of large wreaths made

Given:

⇒ 20x + 30y = 240

Given:

⇒ y = 2x

Substitute  y = 2x  into  20x + 30y = 240 and solve for x:

⇒ 20x + 30(2x) = 240

⇒ 20x + 60x = 240

⇒ 80x = 240

⇒ x = 3

Therefore, Susan will make 3 small wreaths

Substitute found value for x into y = 2x and solve for y:

⇒ y = 2(3)

⇒ y = 6

Therefore, Susan will make 6 large wreaths

Answer:

B

Step-by-step explanation:

This is a distance versus time graph. The slope on a given interval gives you speed.

So if the slope is going upwards, the speed is increasing which means it isnt constant

If going downwards, the speed decreasing, which means it isn't constant

If forming a horinzontal line, it has slope of 0, which means that it has a constant speed

The only time speed is constant is at 4.

B is the answer

Answer:

-2

Step-by-step explanation:

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

Slope

[tex] = \frac{14 - 4}{ - 8 - ( - 3)} [/tex]

[tex] = \frac{10}{ - 8 + 3} [/tex]

[tex] = \frac{10}{ - 5} [/tex]
