Answer:

yes they form a proportion

Step-by-step explanation:

1 to 3 and 7 to 21 are equal

we can check this by multiplying each number in the 1 to 3 ratio by 7 to make it equal with the other ratio, 7 to 21.

Answer:

30[tex]\pi[/tex] or 94.2 feet

Step-by-step explanation:

Use the area formula to find the radius:

A = [tex]\pi[/tex]r²

706.5 = 3.14r²

225 = r²

15 = r

Then, find the circumference using the formula:

C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex](15)

C = 30[tex]\pi[/tex]

So, the circumference of the garden is 30[tex]\pi[/tex] or approximately 94.2 feet

Answer:

X IS LESS THAN 6

Step-by-step explanation:

because x < 6 that means 6 is more than x so x has to be less than 6. your welcome;

Answer:

Step-by-step explanation:

190 people=3 busses

570:190=3

so, 570 people= 190p. + 190p. +190p.= 3 busses +3 busses + 3 busses

Step-by-step explanation:

190 people = 3 busses

570:190=3

Answer:

#7-$50.40 #8-$12,952.50 #9-$44.11 #10-$90.61

Step-by-step explanation:

#7- 18 ÷100= .18 .18(280) = $50.40

#8- you already have

#9- 5.53÷100 = .0553 .0553(462.82)= $44.11

#10- you already have

Answer:

The equations that have one solution are 9=3(5x–2) and 6x–(3x+8)=16

Step-by-step explanation:

To determine which equations have one solution, we will determine the solution(s) to all the equations (that is, find the value of the unknown, x).

1. 8x–3x+5=5x–2

This becomes

5x+5=5x-2

Subtract 5x from both sides

5x-5x+5 = 5x-5x-2

0+5 = 0-2

This equation has no solution

2. 9=3(5x–2)

First, open the bracket by distributing 3

∴ 9 = 15x - 6

Then, add 6 to both sides

9+6 = 15x -6 +6

15 = 15x

Divide both sides by 15

15/15 = 15x/15

1 = x

∴ x = 1

This has one solution.

3. 6x–(3x+8)=16

Open the bracket by distributing –1

6x -3x -8 = 16

3x - 8 = 16

Add 8 to both sides

3x -8 +8 = 16 + 8

3x = 24

Divide both sides by 3

3x/3 = 24/3

x = 8

This has one solution.

4. 9x+4–x=4(2x+1)

This becomes

9x -x +4 = 4(2x+1)

Then, 8x +4 = 4(2x+1)

Open the bracket by distributing 4

8x +4 = 8x +4

This is true for any value of x.

Hence, the equations that have one solution are 9=3(5x–2) and 6x–(3x+8)=16.

Answer:

B) -1/2

C) {30, 150}

Step-by-step explanation:

Question 3)

We can see that the angle equals 210* which equals 7pi/6 (in radians)

The coordinates would be [tex](\frac{-\sqrt{3} }{2}, \frac{-1}{2})[/tex]

Since the problem is asking for sinθ, we will use -1/2 (the y-coordinate)

So the answer is B) -1/2..

Question 4)

If the criteria of the answer is that it must be between 0 < θ < 360 and it must have a y-value of 1/2 in its coordinate (sinθ = 1/2), then we will choose angles that meet this criteria. When we look at the unit circle (see the attached) we can see that only the angles of 30* and 150* match this answer, so our answer is c.

Answer:

92

Step-by-step explanation:

1,374 ÷ 15 = 91.6

you can't have .6 of a box so you add an extra one to make 92

Answer:

4.11

Step-by-step explanation:

7(p-9)=-34.3

first you want to apply what is outside of the parenthesis to the inside of the parenthesis. After applying you would get

7p-63=34.3

Next you wanna get the variable to one side and the whole numbers to the other side. to do this you add 63 to each side, you end up with

7p=28.8. Then you want to get p by itself. In order for this to happen you divide each side by 7 to get p=4.114285714
