explain how multiplying 4/10 and 3/10 is similar to multiplying 0.4 and 0.3 (please only answer if you for sure know the answer!!)

Answer:

its the last one

Step-by-step explanation:

the sign flips when you divide by a negative

9514 1404 393

Answer:

  z ≥ 3

Step-by-step explanation:

When you divide by the negative coefficient of z, you reverse the inequality symbol:

  -8z ≤ -24

  z ≥ -24/-8 . . . . divide by -8

  z ≥ 3

This graphs as a solid dot at 3, with the line extending to the right (to greater values).

Answer:

a) y = 0.55x + 75

b) $108

Step-by-step explanation:

a) to find the equation represent the sequence use the y=mx+b formula

y = total price

m = cost per mile

x = miles driven

b = flat fee

Therefore y = 0.55x+75

b) To figure out the cost of driving 60 miles you use the equation y = 0.55x + 75

y = 0.55 X 60 + 75

= 108

Therefore the cost of renting the truck and driving 60 miles is $108

Step-by-step explanation:

Question: 1

Jessica = $8

Ciara = $12 + 4 $16

Now we times both values.

16 x 8 = $128

8 x 16 = $128

They would both need to work 8 hours ft=or the same money.

Question 2:

$8 x 5 = $40

$16 x 5 =$80

Jessica will be less expensive.

Answer: 3 hours

Jessica=$8

Ciara= $4 + $12

8*3= $24

4*3= $12 +$12= $24

Because Ciara has an additional $12 fee, you have you add it on to her total.

Answer:

The Y-intercept is 1

It is where the line meets the y-axis

~PumpkinSpice1

[tex]==================================[/tex]

Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept).

Let's look at this graph and see if we can identify the y-intercept of the line.

If we look at our graph, we'll see that the line touches the y-axis at (0, 1).

[tex]\pmb{Note:-}[/tex] Remember, y-intercepts have an x-coordinate of 0.

And guess what the y-coordinate is? Yes, it's the y-intercept of the line.

Hence, the y-intercept of the line is

Answer:

$4,194

Step-by-step explanation:

First, you need to subtract the 1,804 from the the total, which will give you 4,780. Divide this by two to get the cost of room and board, which is 2390. To find the tuition fee, add 2,390 and 1,804, and that equals $4,194.

Answer:

similar; AA similarity; RQP

Step-by-step explanation:

We know that angle R is congruent (equal) to angle C.

We know that angle Q is congruent to angle B.

Because they ordered their triangle statement CBA, and we know that R matches C and Q matches B, you should order your statement as RQP.

Answer:

C / 20

Step-by-step explanation:

Number of students in the baking club = 10

Each student made 2 chocolate cakes

Total cakes = number of students × number of cakes per student

= 10 × 2

= 20

Total cups of flour used by 10 students = C cups

Amount of flour for one cake = Total cups of flour / Total cakes

= C / 20

The expression that represents the amount of flour for one cake = C / 20

Answer:

7/-6

Step-by-step explanation:

slope formula- (y2-y1)/(x2-x1)

plug in the numbers- (0+7)/(-5-1)

Let total number of questions be x.

According to the question,

80% of x is 32

or 80/100 × x = 32

or x = 32 ÷ 80/100

or x = 32 × 100/80

or x = 32 × 10/8

or x = 4 × 10

or x = 40

So, total number of questions is 40.

Answer:

A.) -5

Step-by-step explanation:

Slope Formula --->     [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]       m = slope

[tex]m = \frac{2 - (-3)}{-2 - (-1)}[/tex]

Eliminate negatives:

[tex]m = \frac{2 + 3}{ -2 + 1}[/tex]

Solve:

[tex]m = \frac{5}{-1}[/tex]

Simplify:

[tex]m = -5[/tex]

See attachment for math work and answer.

The equation we are looking for is parallel to the given equation. This means both equations have the same slope.

Answer:

y = -5x + 32

Step-by-step explanation:

y = -5x + 1

=> (d): 5x + y - 1 = 0

d' is parallel to the given line and passes through the given point

=> (d'): passes through (5;7)

           // (d): 5x + y - 1 = 0

=> (d'): 5x + y - 32 = 0 <=> y = -5x + 32

Answer:

The slope is 3.

Step-by-step explanation:

To find the slope of this line you just have to figure out the rise over run. The rise is positive because it's going up. The run is also positive because it's going to the right. The rise would be 2 because that's how many units up the line goes until it crosses the y-intercept. The run is 3 because that's how many units over until it crosses the y-intercept. But, in this case we are not using a fraction so we just use the run which is 3.

Hope this helps! Stay safe and please mark brainliest!

Answer:

505

Step-by-step explanation:

you first do 2020x2020 because you can see from the pattern, the inside squares are 1x1, 2x2, 3x3, so the 2020th inside squares would be 2020x2020. then, you would do 2020x4 for the shaded squares because if you see from the pattern, its 1x4, 2x4, 3x4, so the 2020th would be 2020x4. then you divide [tex]\frac{2020*2020}{2020*4}[/tex] which is 505.

Answer: 84

Step-by-step explanation:

21 * 4=84

Always multiply by 4.

Answer:

Step-by-step explanation:

To solve this, we will create a proportion.

The proportion will show the ratio of ABC to EDC and allow us to solve for x.

20 - x / 20 =  x / 5

100 -  5x = 20x

100 - 5x + 5x = 20x + 5x

100 = 25x

100 / 25 = 25x / 25

4 = x
