Answer:

$4.05

Step-by-step explanation:

We must divide 4 by 8. We get 0.5. 0.5 stands for $0.5. Then we add 0.5 to 4, which equals $4.05.

Answer:

x + 3 meters

Step-by-step explanation:

We know that the area of a rectangle is length times width, so if we call the length y, we'll get y * (x - 3) = x² - 9.

y = (x² - 9) / (x - 3)

y = (x + 3)(x - 3) / (x-3)

y = x + 3. Hope this helps!

Answer: 48 minutes

Step-by-step explanation:

If there are 7 people painting 7 walls, we can assume that 1 person is painting 1 wall. Altogether they can each paint in 48 minutes.

If there are 20 people painting 20 walls, it would also equal 48 minutes because each person can paint in that time.

Answer:

137 minutes.

2 hrs and 17 minutes

Step-by-step explanation:

The painting of each wall takes 6.85 minutes.

48 / 7 = 6.85.

therefore if there are 20 walls, it must take 20 people 2 hrs and 17 mins

20 x 6.85 = 137minutes.

Answer:

$1200

Step-by-step explanation:

Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.

Last month she had 100 subscribers. This month, 30 new subscribers joined and 10 members canceled their subscription. The amount of subscribers she has now is:

100 + 30 - 10 = 120

This means that this month, Kiersten will earn:

10 * 120 = $1200

Answer: The area of this hub cap is about  470.46  square centimeters.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Replacing with the values given:

76.87 = 2 (3.14) r

Solving for r (radius)

76.87/ (2x 3.14) =r

r = 12.24 cm

To find the Area:

A = 3.14 (12.24)^2

A = 470.46 cm2

If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.

Feel free to ask for more if needed or if you did not understand something.

Answer:

  1 2/3

Step-by-step explanation:

Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...

  4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15

Then either of the remaining sides is half this value, or ...

  (4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3

Each of the remaining sides has length 1 2/3.

Answer:

1. B

2. C

Step-by-step explanation:

1. In this, we already know one side and one angle are congruent. For the triangles to be congruent by SAS, another side is necessary. Thus CB = FE

2. Here, we see that one set of sides are congruent. We see another set of angles are congruent as well. We also know that the center angle is congruent as the angles are formed by two straight lines intersecting. Since we  see 2 next door angles and the side beside it congruent, they are proven congruent by AAS.

Answer:

B (-22 ,  4)

Step-by-step explanation:

-16=(-10+x)/2

*2      *2

-10+x=-32

+10       +10

x=-22

6=(8+y)/2

*2      *2

12=8+y

-8    -8

4=y

so B(-22,  4)

The coordinates of point B is (-22, 4).

Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.

If we have the end points (x', y') and (x'', y'').

The mid point is ((x' + x'')/2, (y' + y'')/2).

Given that one of the end point A is at (-10, 8).

The mid point is at P(-16, 6).

Let the other point be B(x, y).

(-10 + x) / 2 = -16 and (8 + y) / 2 = 6

(-10 + x) / 2 = -16

⇒ -10 + x = -32

⇒ x = -32 + 10

⇒ x = -22

(8 + y) / 2 = 6

8 + y = 12

y = 12 - 8

y = 4

Hence the coordinate of the other point is B(-22, 4).

Answer: She should run 1 1/3 miles 5 times a week.

Step-by-step explanation:  I converted 3/4 to a decimal to have 1.75 and I multiplied it by 5 because that is how many times she will be running 1.75 miles in a week, I got 8.75. So that means if she runs 1.75 miles for 5 days she will run a total of 8.75 miles. Then I converted 1/4 into a decimal and now have 2.25, then I multiplied 2.25 by 3 and got 6.75. So I saw that 8.75 is greater than 6.75,

So the correct answer is: she should run 1 3/4 miles 5 times a week

============================================================

Explanation:

Starting at (4, -1) and moving four units up will have us arrive at (4, 3). We add 4 to the y coordinate and keep the x coordinate the same. The algebraic rule is stated as [tex](x,y) \to (x,y+4)[/tex].

Next, we reflect over the y axis. This will have us flip the sign of the x coordinate while keeping the y coordinate the same. The algebraic rule for this kind of reflection is [tex](x,y) \to (-x,y)[/tex]. The point (4,3) reflects over the y axis to get to (-4,3)

So we started at (4, -1), then moved four units up to get to (4,3) and then reflected over the y axis to get to (-4, 3) which is the final stop.

Answer:

4/9 cup of sugar

Step-by-step explanation:

[tex]\frac{1}{3} cup of sugar= \frac{3}{4} cup of flour[/tex]

[tex]? cup of sugar=1 cup of flour[/tex]

so crisscross them and finally you'll get

1/3*4/3=4/9

For 1 cup of flour, 4/9 cups of sugar is needed.

Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -

A : B ∷ C : D

AND

A x D = B x C

Product of extremes equal to product of means.

Given is a recipe that requires 1/3 cup of sugar for every 3/4 cup of flour.

Now -

For 1/3 cup of sugar = 3/4 cup of flour is needed.

For 1 cup of flour = (1/3)/(3/4) cups of sugar = 1/3 x 4/3 = 4/9 cups of sugar is needed.

Therefore, for 1 cup of flour, 4/9 cups of sugar is needed.
