a : 0 ≤ x ≤ 55
b : 0 ≤ x ≤ 22
c : 0 ≤ x ≤ 8.8
d : 0 ≤ x ≤ 2.5

Answer:Equivalent ratios are ratios that make the same comparison of numbers. Two ratios are equivalent if one can be expressed as a multiple of the other.

Answer:

[tex] \pi \: 4 \: 8[/tex]

Answer:

[tex]\pi, 4, 8[/tex]

Step-by-step explanation:

Note that [tex]\pi\approx3.14[/tex]. As [tex]3<3.14<4[/tex], [tex]\pi[/tex] comes before [tex]4[/tex].

Clearly [tex]4<8[/tex], so [tex]4[/tex] comes before [tex]8[/tex].

The only possible ordering is [tex]\boxed{\pi, 4, 8}[/tex]

Since they have twice as many games won as lost there are 3 parts.

The losing part and the two winning parts.

The winning part is [tex]\frac{2}{3}[/tex] the games while the losing part is [tex]\frac{1}{3}[/tex] the games.

Just multiply [tex]\frac{2}{3}[/tex] by the games played to find the games won.

[tex]\frac{2}{3} (96)=\frac{192}{3} =64[/tex]

The ravens won 64 games.

Make a system of equations.

Let s be the number of skips interviews and w be the number of woodys interviews.

s=w-8

s+w=20

Then just use algebra to rearrange and find each persons interviews.

For this one we can rearrange the second equation to get s=20-w.

Since we have two solutions for s we can set them equal.

w-8=20-w

2w-8=20

2w=28

w=14

Now that we have the number of woodys interviews substitute it into the first equation to get skips interviews.

s=w-8

s=14-8

s=6

So skip had 6 interviews and woody had 14 interviews.

12.

Make a system of equations

y-x=7

x+y=33

Then just use algebra to rearrange and find each amount of items.

Start by solving with substitution. (Elimination could work too im just going to use substitution.)

y-x=7

y=7+x

Substitute into the second equation

x+(7+x)=33

2x+7=33

2x=26

x=13

Now plug this x value back into the first equation

y-13=7

y=20

The number of items on one list is 13 and the number of items on the second list is 20.

Answer:

y = 2/5x - 5

Step-by-step explanation:

(-10,-9) and (10,-1)

Slope: (-1 - - 9) / ( 10 - - 10)

Slope = 8/20 = 2/5

b = -9 - (2/5(10)

b = -5

The equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Where x₁ - x coordinate, y₁ - y coordinate, m - slope

Slope: (-1 - - 9) / ( 10 - - 10)

m = Slope = 8/20 = 2/5

Now intercept;

b = -9 - (2/5(10)

b = -5

Now Write the equation as

y = 2/5x - 5

Hence, the equation of the line that passes through the point (−10,−9) and (10,-1) is; y = 2/5x - 5

Answer:

10

Step-by-step explanation:

Line BC is equal to line AD

∴

x + 17 = 3x + 7

x - 3x = 7 - 17

-2x = - 10

-2x / -2 = - 10 / -2

x = 5

AD

3x + 7

3(5) + 7

15 + 7

CD

2x - 6

2(5) - 6

10 - 6

BC

x + 17

5 + 17

22

AB

Line AB is equal to line CD therefore its length is 4

Answer:

x = 5

AB = 4

BC = 22

CD = 4

AD = 22

Answer:

30$

Step-by-step explanation:

lets assume you didn't have a coupon then the total bill would have been 120$

so for 4 friends including u the bill would have been 120$

: 4 friends = 120 $

for : 1 friend = x$

cross multiply

4x = 120 × 1

4x =120

divide both sides by the coefficient of x

x =120 \ 4

x = 30$

therefore: 1 friend = 30$

Answer:

- 5 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )

= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )

= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]

= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]

= [tex]\frac{-21-11}{6}[/tex]

= [tex]\frac{-32}{6}[/tex]

= - [tex]\frac{32}{6}[/tex]

= - 5 [tex]\frac{2}{6}[/tex]

= - 5 [tex]\frac{1}{3}[/tex]

Circumference is [tex]2\pi r[/tex]

Find your radius

[tex]2\pi r=62.8\\\pi r=31.4\\[/tex]

Let [tex]\pi =3.14[/tex] for simplicity

r=[tex]\frac{31.4}{3.14}[/tex]=10

Now use the equation for the area of a circle to find the area of the clock face.

Area of a circle is [tex]\pi r^{2}[/tex]

Area of clock face is [tex]\pi (10^{2} )[/tex]

=[tex]100\pi[/tex]

U just divide the amount of money by 5. (im pretty sure thats all u do)

Step-by-step explanation:

If X represents the length of the side of a cube, the formula for the surface area of the cube, S =?

solution :

the area of each face of the cube = side × side

= X × X = X²

the cube has 6 similar faces, so the surface area of the cube could be:

S = 6 × X² = 6X²

Answer:

Surface Area = 6 × S²

Step-by-step explanation:

the surface area fo the cube :

if lenght = S, the surface area fo the cube :

SA = 6 × lenght × lenght

SA = 6 × S × S

SA = 6 × S²
