I need help with this PLEASE

I would say it’s B! I know it isn’t A because we can say no to A since it’s such a small number and (-4,-2) to (4,6) isn’t 24 nor bigger then 100 so the only possible answer is B

I hope this helps and makes sense!

Answer:

D y=50x + 25

Step-by-step explanation:

The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.

Answer:

D

Step-by-step explanation:

y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)

That means the equation is y = 50x + 25

Area formula: a = l * w

a = 8 * 4.5

a = 36

Perimeter formula: p = 2l * 2w

p = 2(8) + 2(4.5)

p = 16 + 9

p = 25

Best of Luck!

Answer:

square root of 113 or 10.63014581

Step-by-step explanation:

Answer:

[tex]\sqrt{113}[/tex]

Step-by-step explanation:

Using pythag theorem:

Length of the hypotenuse is [tex]\sqrt{7^{2}+8^2 }[/tex]

Thus [tex]\sqrt{113}[/tex]

That would be [tex]\pi(32/2)^2\approx804.25\mathrm{ft^2}[/tex].

Answer:

r = 24

Step-by-step explanation:

The formula for circumference is

C = 2*pi*r

48 pi = 2 * pi *r

Divide each side by  2pi

48 pi / 2pi = 2 * pi *r/ 2pi

24 = r

Answer:

Fine the area of the square, then the area of the circle. Subtract the area of the circle from the area of the square and you will get the remaining shaded area.

Answer:

Isn't this an AoPS Problem?

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

both A and B are false, because no value would allow Sari to pay Raymond and then still have 30 dollars so it has to be C or D

42 - 24 = 18                18 times 3 is 54, so this appears to work

30 + 24 = 54

42 - 18 = 24       24 times 3 is not 48, so C is incorrect

30 + 18 = 48

Answer:

(B)15,36,39

Step-by-step explanation:

To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.

By Pythagoras Theorem: [tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]

In  15,30,35

[tex]35^2\neq 15^2+30^2\\1225\neq 1125[/tex]

In 15,36,39

[tex]39^2=36^2+15^2\\1521=1521[/tex]

In 15, 20, 29

[tex]29^2\neq 15^2+20^2\\841\neq 625[/tex]

In 5,15,30

[tex]30^2\neq 15^2+5^2\\900\neq 250[/tex]

We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.

Answer:

Third Answer or 62 degrees.

The measure of angle p can be found by subtracting the measures of angles q and r from 180 degrees.

The measure of angle p can be determined by subtracting the measures of angles q and r from 180 degrees. Let's say angle q measures 50 degrees and angle r measures 70 degrees. By subtracting these values from 180, we can find that the measure of angle p is 60 degrees.

Answer:

D. ( 3.6 , 2.2)

Step-by-step explanation:

Given

x + y = 5.8....equation 1

y = 2x - 5 ......equation 2

Putting equation 2 in equation 1

x + 2x - 5 = 5.8

3x = 5.8 + 5

3x = 10.8

Therefore x = 3.6

Now

y = 2 * 3.6 - 5

= 7.2 - 5

= 2.2

Her average weekly income in August was $200.

Step-by-step explanation:

To find the income in july :

Given that,

Let,

'x' be the 100% of income she got in July.

Therefore, the income $207 in September is 115% of x.

⇒ 115% of x = 207

⇒ 1.15 × x = 207

⇒ x = 207 / 1.15

⇒ x = 180

∴ Her average weekly income in July was $180.

To find the income in August :

Given that,

Let,

'y' be the 100% of income she got in August.

Therefore, the income $180 in July is 90% of y.

⇒ 90% of y = 180

⇒ 0.9 × y = 180

⇒ y = 180/0.9

⇒ y = 200

∴ Her average weekly income in August was $200.

her average weekly income in August was $200 .

Step-by-step explanation:

Let in July income was x , So in September :

⇒ [tex]x+\frac{15x}{100}[/tex]

According to question , her average weekly income in September was $207 i.e.

⇒ [tex]x+\frac{15x}{100}=207[/tex]

⇒ [tex]\frac{115x}{100}=207[/tex]

⇒ [tex]x=207(\frac{100}{115})[/tex]

⇒ [tex]x=180[/tex]

Now , average weekly income in July was 10% less than it was in August , let income of august = y,  i.e.

Income in august = [tex]180+\frac{August(10)}{100}[/tex]

⇒ [tex]y=180 + \frac{y(10)}{100}[/tex]

⇒ [tex]\frac{9}{10}y=180[/tex]

⇒ [tex]y=\$200[/tex]

Therefore , her average weekly income in August was $200 .

Answer:

A= -18

Step-by-step explanation:

-8-3(-18)= 46= -18

Answer:

a=-18

Step-by-step explanation:

Let's break this down step by step.

-8-3a=46

Since 3a has a variable, a, we want to get it by itself. So the first step is to do the inverse operation and add 8 on both sides. That leaves this equation:

-3a=54

The 3a is -3a because of the subtraction sign in front. Now we divide on both sides because we want the variable, a, to be by itself. That leaves this simplified expression.

a=-18.

Now, let's work it out in context of the problem.

-8-3x-18=46

3x-18 is -54, and -8-(-54), it would become 46.

Which digit should go in the box to

make the next number divisible

between 2, 3 and 9? 8 ,? 48

Let x be the number, then the number will look like this:

8x48

This number is already divisible by 2, because it ends with an even number.

Now we need to check for divsibility by 3.

For this to be divisible by 3, the sum of the digit should be a multiple of 3.

[tex]8 + x + 4 + 8 = x +20[/tex]

We know if a number is divsible by 9, it is also divsible by 3.

So

[tex]x + 20=9,18,27,....[/tex]

The least positive solution is

[tex]x + 20 = 27[/tex]

[tex]x = 27 - 20[/tex]

[tex]x = 7[/tex]

Therefore 8748 is divsible by 2,3, and 9.

Answer:

92⁰

Step-by-step explanation:

a = 35⁰ ( vertically opposite )

b = 53⁰ (vertically opposite )

a + b + x = 180⁰ (Angle sum property of triangle)

35⁰ + 53⁰ + x = 180⁰

x = 180⁰ - 88⁰

x = 92⁰

Answer:

[tex]x = 97 \: \: degrees[/tex]

Step-by-step explanation:

[tex]a = 35 \\ b = 53 \\ (vertically \: \: opposite \: \: angles)[/tex]

[tex]35 + 53 + x = 180 \\ 86 + x = 180 \\ x = 180 - 83 \\ x =9 7 \: \: degrees[/tex]

sum of the angles in a triangle is 180 degrees.

Step-by-step explanation:

The length of rectangle is 48 yards and width of the rectangle is 8 yards, if the perimeter of the rectangle is 112 yards.

Step-by-step explanation:

The given is,

                   The perimeter of the rectangle is 112 yards

                   The length of a rectangle is six times it's width

Step:1

          Let, p - Perimeter of the rectangle

                   l - Length of the rectangle

                 w - Width of the rectangle

Step:2

        Formula for perimeter of rectangle,

                    [tex]Perimeter, p = 2(l+w)[/tex]............................(1)

        From given,

                      p = 112 yards

                       l = 6w                            ( ∵ From given)

                     w = w

        Substitute the values,

                   112 = 2 ( 6w + w )

                   112 = 2 ( 7w )

                   112 = 14w

                    w = 8 yards

         From the w value, l becomes

                     l = 6w

                     l = 6 × 8

                   l  = 48 yards

Result:

       The length of rectangle is 48 yards and width of the rectangle is 8 yards, if the perimeter of the rectangle is 112 yards.

Answer:

1055 lbs.

Step-by-step explanation:

Since 1 ton is 2000 pounds, half a ton is 1000 pounds. The wheelbarrow weights 55 pounds in itself, so the total weight will be 1000 + 55 = 1055 lbs.

Answer:

Not on there but it is 76in2

Step-by-step explanation:

Starting with the trapezoid. We know that a trapezoid can be split into 2 triangles and 1 rectangle. So the area of the trapezoid will be 4+32+4 which is 40 now that we know the trapezoid's area we can find the rectangle's area. The rectangle's area will be 12x3 which is 36. So, you would add both:40+36= 76in2.

Step-by-step explanation:

Total bags = 8

Candies in each bag = 7 candies

So Now

Total candies in the package = 7*8 = 56
