Answer:

40% of 800 is 320

Step-by-step explanation:

0.40×800=320

Using the principle of proportional relationship, the 42 L of gas can go for a further 165 km

Consumption rate = 8L for 100 km

Km per Litre :

8L = 100km

1 L = m

8m = 100

m = (100 ÷ 8)

= 12.5 kilometer per Litre

Number of kilometers for 42 L

12.5 km = 1 L

m = 42 L

Cross multiply

m = 12.5 × 42

m = 525 km

The difference in the distance = 525 - 360 = 165 km

Therefore, the gas can go for a further 165 km

Answer:

Step-by-step explanation:

I've attached a picture, and I hope it's clear and understandable.

Answer: k=9

Step-by-step explanation:

Parallel lines have the same slope. y=mx+b, where m is the slope. The reference line, y = 6x-5 has a slope of 6. The new line must therefore also have a slope of 6. The slope is the Rise/Run, the change in y for a change in x.

The two points on the new line are (10,2k) and (13,4k). Rise over run for this new line is (4k-2k)/(13-10) or 2k/3. This must be equal to 6,

2k/3 = 6

2k = 18

k = 9

Answer:

First we need to solve the linear equation for y because we need to get the slope. Once we have the slope we need to convert it to its negative reciprocal, this means to just change the sign of the slope and flip it. The negative reciprocal is always perpendicular to the original slope.

2y = - 6x + 8

y = (-6x/2) + 8/2

y = - 3x + 4

The current slope is -3 or -3/1

The negative reciprocal is 1/3

Answer:

y = 20x + 0.15s

Step-by-step explanation:

Shew makes $20 par hour, so for x hours, she makes 20x.

She makes 15% commission on the sales, s. 15% = 0.15,so for the sales, s, she makes 15% * s = 0.15s.

The total she makes is 20x + 0.15s

Answer: y = 20x + 0.15s

The equation in the form y = mx + cs models Emma’s situation is

y = 20x + 0.15s

Shew makes $20 par hour, so for x hours, she makes 20x.

The slope-intercept of the line y= mx+c

Where y co-ordinate

x-  x co-ordinate

m=slope of the given line

C-y intercept.

She makes 15% commission on the sales, s. 15% = 0.15,

So for the sales, she makes

15% * s = 0.15s.

The total she makes is 20x + 0.15s

y = 20x + 0.15s

Step-by-step explanation:

5⁴×5² = 5⁶

10⁶/10³ = 10³

so, we have 5⁶/10³ = 15.625

and in scientific notation we have to write the first digit (which is not 0) in front of the decimal point, and the following digits of the number as pairings after the decimal point, and then indicate a multiplication with a power of 10 to tell us the right position of the decimal point in the plain number.

so, 15.625 as plain number is

1.5625 × 10¹ in scientific notation.

therefore option 1 is correct.

We replace m with 5 in the function.

f(m) = 1 - 4(m/2) becomes f(5) = 1 - 4(5/2)

then we solve the numbers in the parenthesis first

= 1 - 4 (5/2)

Hundreds: 100

Tens: 60 (6 tens)

Ones: 5

Tenths: 0.03 (3 hundredths)

Hundredths: 0.008 (8 thousandths)

So, the correct expanded form for the number 165.038 is:

100 + 60 + 5 + 0.03 + 0.008

Answer: B. (4t - 3)(t - 6)

Step-by-step explanation:

(4t - 3)(t - 6)

= 4t^2 - 24t - 3t + 18

= 4t^2 - 27t + 18

Answer:

B

Sum = -27

Product = 18*4 = 72

Factors = (-24) ; (-3)     {(-24)*(-3)=72 & (-24) + (-3) = -27}

4t² -27t + 18 = 4t² - 24t - 3t + (-3)*(-6)
