Answer:

10 %

Step-by-step explanation:

15 mn = 1/4 h

We have :

$\frac{\frac{1}{4} }{\frac{5}{2} } =\frac{1}{4} \times \frac{2}{5} =\frac{2}{20} =\frac{1}{10}=0.1$

Then the percentage that 15 mn represents of 5/2 h is :

0.1 × 100 = 10 %

When rounded to the thousands place, which of the numbers below round to 89,000? Select all that apply. A) 89,458 B) 88,450 C) 9

slega [8]

Answer:

A) 89,458 and

E) 88,615

When rounded to the thousands place, the numbers above will round to 89,000

Step-by-step explanation:

A) 89,458

When rounded to the thousands place, the number above will round to 89,000 because 458 is less than 500 .

In rounding we check the number next to the number which is to be rounded.

If that number is less than 5 it is dropped off and if it is greater and equal to 5 it is added to the next number.

In this number we check the hundreds place to round to the thousands number.

B) 88,450

When rounded to the thousands place, the number above will round to 88,000 because 450 is less than 500 .

C) 90,054

When rounded to the thousands place, the number above will round to 90,000 because 0 is less than 5 at the hundreds place .

D) 89,905

When rounded to the thousands place, the number above will round to 90,000 because 905 is greater than 500 .

E) 88,615

When rounded to the thousands place, the number above will round to 89,000 because 615 is greater than 500 .

Solving Linear Equat<br> Solve the linear equation:<br> 3.4 + 2(9.7 – 4.8x) = 61.2

JulijaS [17]

Answer:

Step-by-step explanation:

Simplifying

3.4 + 2(9.7 + -4.8x) = 61.2

3.4 + (9.7 * 2 + -4.8x * 2) = 61.2

3.4 + (19.4 + -9.6x) = 61.2

Combine like terms: 3.4 + 19.4 = 22.8

22.8 + -9.6x = 61.2

Solving

22.8 + -9.6x = 61.2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-22.8' to each side of the equation.

22.8 + -22.8 + -9.6x = 61.2 + -22.8

Combine like terms: 22.8 + -22.8 = 0.0

0.0 + -9.6x = 61.2 + -22.8

-9.6x = 61.2 + -22.8

Combine like terms: 61.2 + -22.8 = 38.4

-9.6x = 38.4

Divide each side by '-9.6'.

x = -4

Simplifying

x = -4

AlekseyPX

Answer:

y = 0.5

x = 4 - y (0.5)

3.5 = 4 - 0.5

------------

3x - 10 = y

3(3.5) - 10 = y

10.5 - 10 = y

0.5 = y

Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

stich3 [128]

Answer:

Equation of line is $\mathbf{y=-3x+3}$

Option A is correct.

Step-by-step explanation:

We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.

The equation will be of slope-intercept form: $y=mx+b$

where m is slope and b is y-intercept

We are given slope m =-3, we need to find y-intercept b

Finding y-intercept

using slope m=-3 and point (-1, 6)

$y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3$

So, y-intercept b is 3

Now the equation of line having slope m= -3 and y-intercept b = 3 is

$y=mx+b\\y=-3x+3$

Equation of line is $\mathbf{y=-3x+3}$

Option A is correct.
