Answer:

I cannot see the x values so I cannot help with part D, but part C is y=3.50x+9.50

Step-by-step explanation:

the question states there is a fee of 9.50 for shipping costs, which is constant. this means it will be the y intercept in addition, since each shirt costs 3.50 each, the equation is y=3.50x+9.50

Answer: $5.33

Step-by-step explanation:

Bliss was able to collect $18 in total.

Out of this total, she received a $2.00 bronze star donation and the rest were 3 Silver star donations.

This means that the 3 equal silver star donations added up to:

= 18 - 2

= $16.00

This means that each silver star donation was:

= Amount in total / Number of silver stars

= 16 / 3

= $5.33

Answer:

61.25

Step-by-step explanation:

The of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.

Volume of cone is the amount of quantity, which is obtained it in the 3 dimensional space.

The volume of the cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

A cone-shaped party hat has a radius of r=3 inches and a height of h=6.5 inches. The amount of cubic units it occupies is equal to the volume of hat.

Thus, put the values in the above formula as,

[tex]V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=61.26\rm\; in^3[/tex]

Thus, the of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.

Answer:

C

Step-by-step explanation:

first cube :

4 × 3 × 6 = 72 m³

second cube :

4 × 4 × 4 = 64 m³

sum of both cubes :

72 + 64 = 136 m³ ( C )

Answer: p=60

Step-by-step explanation:

Angles on a straight line always add up to 180 degrees.

So, because you have an angle on the straight line with the arrow going up, you have to do:

180-110=70

This will give you the angle inside of the triangle that is next to 110.

Then you would find the angle next to 130 (using the horizontal line) by using the same method so you would do:

180-130=50

This gives you the angle inside the triangle next to 130.

Then because a triangle always adds up to 180 you would add up the 2 angles you have figured out like this:

70+50=120

Then you would take the answer away from 180 like this:

180-120=60

So, p=60

Answer:

5 and 100

8 and 160

9 and 180

12 and 240

Step-by-step explanation:

Since for every one sweatshirt there is $20 collected. Simply plug this in and do the multiplication and division.

5x20 = 100

8x20 = 160

180/20 = 9

12x20 = 240

Answer:

3, 5, 8, 9, 12

60, 100, 160, 180, 240

Step-by-step explanation: the only values that you have full information for is the first column

3, 60

to get from 3 to 60 you would multiply by 20, so for the next column multiply 5 by 20 to get 100

then 8, 160

for the fourth column you would just divide 180 by 20, 9

and finally for the last column you would multiply 12 by 20 to get

240

Answer:

2 5/14 yards

Step-by-step explanation:

Area of the rectangular floor = Length * Width

Given

Area = 8 1/4 square yards

width = 3

1/2 yards

Required

Length

Length = Area/width

Length = (8 1/4)/(3 1/2)

Length = 33/4 ÷ 7/2

Length = 33/4 * 2/7

Length = 33/14

length = 2 5/14 yards

This gives the required length

Answer:

  B.  x = 2√11

Step-by-step explanation:

The square of the length of the diagonal is ...

  d² = 6² + 8² = 36 +64 = 100

Then the length of x is found from ...

  d² +x² = 12²

  x² = 144 -100 = 44 . . . . . subtract d²

  x = √44 . . . . . . take the square root

  x = 2√11

Answer:

8feet

Step-by-step explanation:

Given the equation that models the arch of a school expressed as;

[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]

If the x axis represents the ground;

At the ground level, x = 0

Substitute x = 0 into the equation to get y;

y = -0.5(0+4)(0-4)

y = -0.5(4)(-4)

y = -0.5 * -16

y = 8ft

Hence the y axis at the ground level is 8feet

Answer:

C = √185 or 13.6 units.

and cannot be simplified any further because it is irrational.

Step-by-step explanation:

Since the triangle has sides A = 4 units and B = 13 units. With C as its hypotenuse side, from Pythagoras' theorem C² = A² + B².

So, substituting A and B into the equation, we have

C² = 4² + 13²

C² = 16 + 169

C² = 185

taking square root of both sides, we have

√C² = √185

C = √185

C cannot be simplified any further because it is irrational. It is best expressed as √185 which is a surd. C could also be expressed as a decimal. So using your calculator and taking √185, C = √185 = 13.605 ≅ 13.6 units.

Answer: 17, 19, 21

Step-by-step explanation:

Three consecutive odd numbers: x, x+2, x+4 (since odd numbers occur every other number)

Just to show you that the numbers are x, x+2, and x+4, just say x is 13 then x+2 is 15 and x+4 is 17 (3 consecutive odd numbers)

Now the second equation:

3x = 2(x+4) + 9

three times smallest number (which is x) is equal to 2 times the largest number (x+4) plus 9

Now solve

3x = 2(x+4) +9

3x = 2x + 8 + 9

3x = 2x + 17

x = 17

x+2 = 19

x+3 = 21
