What percent of an hour is `24` minutes?

Answer:

the answer is A cause you divide 7 by 140 and the answer is 22 so 20 is the closest

Answer:

about 8.3 miles an hour.

Step-by-step explanation:

34/4 is 8.5

90/11 is 8.2

average: 8.3

Use the two endpoints to find the slope:

(0,2) and ( 5,5.5)

Slope = change in y over change in x:

Slope = (5.5-2)/(5-0) = 3.5/5 = 0.7

The y intercept is the y value when x is 0, which is 2

Equation: c = 0.7x + 2

Answer:

[tex]S_{15} = 299593[/tex]

Step-by-step explanation:

Given

[tex]262144,\ 32768,\ 4096,\ 512; ...[/tex]

Required

Determine the 15th partial sum

The nth partial sum of a geometric series is:

[tex]S_n = a* \frac{1 - r^n}{1 - r}[/tex]

In this case:

[tex]a = 262144[/tex]

[tex]n = 15[/tex]

r is calculated as:

[tex]r = \frac{32768}{262144}[/tex]

[tex]r = 0.125[/tex]

Substitute values for a, r and n in [tex]S_n = a* \frac{1 - r^n}{1 - r}[/tex]

[tex]S_{15} = 262144* \frac{1 - 0.125^{15}}{1 - 0.125}[/tex]

[tex]S_{15} = 262144* \frac{1}{0.875}[/tex]

[tex]S_{15} = \frac{262144* 1}{0.875}[/tex]

[tex]S_{15} = \frac{262144}{0.875}[/tex]

[tex]S_{15} = 299593.142857[/tex]

[tex]S_{15} = 299593[/tex] -- approximated

Answer:

Option C) Infinitely many solutions is correct option.

Step-by-step explanation:

We need to solve the equation [tex]5x - 7x + 6 = -2(x - 3)[/tex] and find value of x

The equation can be solved using DMAS rule.

Solving:

[tex]5x - 7x + 6 = -2(x - 3)[/tex]

Multiply -2 with terms inside the bracket

[tex]5x - 7x + 6 = -2x +6[/tex]

Now, we will combine like terms. Like terms are those terms that have same variable. In our case 5x, -7x and -2x are like terms and 6,6 are like terms.

[tex]5x - 7x +2x=-6 +6\\7x-7x=-6+6\\0=0[/tex]

Solving the equation we get 0=0 it means that the solution will have infinitely many solutions, because it will be true for every value of x.

So, Option C) Infinitely many solutions is correct option.

Answer:

Step-by-step explanation:

Combine like terms.Like terms have same variable with same exponent

4x³ + 6x - 7 + 3x³ - 5x² - 5x + 9 = 4x³ + 3x³ - 5x² + 6x - 5x  - 7 + 9

                                                  = 7x³ -5x² + x + 2

Answer 1: 5x + 4

Answer 2: 9m + -10y

Step-by-step explanation:

To simplify 3x + 9 + 2x − 5, you have to find the like terms which are 3x and 2x, and 9 and -5. So you get 3x + 2x + 9 - 5 which gives you the result of 5x + 4. Now to simplify 7m + 2 (m − 5y), you have to distribute first, so 7m + (2) (m) + (2) (−5y) which gives you 7m + 2m + −10y. So now you just have to add. 7m + 2m = 9m and then you have -10y so basically the answer is 9m + -10y.

Answer:

Matching the scenario with the correct type of problem:

a. one mean

b. one proportion

c. one proportion

d. one mean

Step-by-step explanation:

A one-proportion problem is tested using the one-sample proportion test.  This estimates the proportion of a population by comparing the proportion to a target or reference value.  On the other hand, a one-mean problem is tested using the one-sample t-test.  This tests whether a population mean is significantly different from some hypothesized value.

Answer:

Step 1 should be (14.4+18)...PEMDAS

Step-by-step explanation:

The expression Rakim wrote for step 1 is incorrect therefore the correct solution will give 5.45.

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given an expression as;

1/12(14.4+18)+2.75.

Part A;

Rakim starts to evaluate the expression.

Step 1: first solve the bracket;

1/12(14.4+18)+2.75.

1/12(32.4) + 2.75.

2.7+ 2.75.

= 5.45

The expression Rakim wrote for step 1 is incorrect therefore the correct solution will give 5.45.

Answer:

Volume of syrup A = 120 quarts

Volume of syrup B = 280 - 120 = 160 quarts .

Step-by-step explanation:

Syrup A : 2 parts sugar , 8 parts of water .

Total = 10 parts

Syrup B : 3 parts sugar , 5 parts of water .

Total = 8 parts .

Mixture required 280 quarts , 3 parts sugar , 7 parts water

In 280 quarts , sugar = 280 x 3  / ( 3 + 7 )

sugar = 84 parts

Let volume of syrup A be x , volume of syrup B = 280 - x

sugar A =  2 x / 10 = 0.2 x

sugar B = 3 ( 280 - x ) / 8 = .375 ( 280 - x )

Total sugar =  .2 x + .375 ( 280 - x ) = 84 .

.2 x + 105 - .375 x = 84

105 - 84 = .375 x - .2 x = .175 x

.175 x = 21

x = 21 / .175 = 120

Volume of syrup A = 120 quarts

Volume of syrup B = 280 - 120 = 160 quarts .

John mixes 120 quarts of syrup A and 160 quarts of syrup of B together to get 280 quarts of syrup that is 3 parts sugar and 7 parts water.

Given that,

John has two different sugar syrups.

Syrup A is 2 parts of sugar and 8 parts of water, and Syrup B is 3 parts of sugar and 5 parts of water.

We have to determine,

How much of each should john mix together to get 280 quarts of syrup that is 3 parts sugar and 7 parts water.

According to the question,

Syrup A: 2 parts sugar, 8 parts of water.

Total number of parts = 10 parts

Syrup B : 3 parts sugar, 5 parts of water.

The total number of parts  = 8 parts.

The mixture required 280 quarts, 3 parts sugar, 7 parts water,

In 280 quarts, parts of sugar are,

[tex]= \dfrac{280 \times 3 }{ ( 3 + 7 )}\\\\= \dfrac{280 \times 3}{10}\\\\= 84[/tex]

Let the volume of syrup A be x,

And the volume of syrup B be 280 - x

[tex]Sugar\ A = \dfrac{2x}{10} \\\\Sugar \ A = 0.2 x[/tex]

[tex]Sugar \ B = \dfrac{3 ( 280 - x ) }{8 }\\\\Sugar \ B= .375 ( 280 - x )[/tex]

The total amount of sugar is,

[tex]0.2 x + 0.375 ( 280 - x ) = 84 \\\\0.2 x + 105 -0 .375 x = 84\\\\105 - 84 = 0.375 x - 0.2 x = 0.175 x\\\\ 0.175 x = 21\\\\x = \dfrac{21}{0.175}\\\\x = 120[/tex]

Therefore,

The volume of syrup A = 120 quarts

Volume of syrup B = 280 - 120 = 160 quarts

Hence, John mixes 120 quarts of syrup A and 160 quarts of syrup of B together to get 280 quarts of syrup that is 3 parts sugar and 7 parts water.
