Answer:

2250 m

Step-by-step explanation:

30 cm = 0.3 m

1 : 75  :: 0.3 : x

Product of extremes = product of means

1 *x = 75 * 0.30

   x = 75 * 0.30

 x = 22.5 m

Answer:

22.5 m

Step-by-step explanation:

Convert to meters

.3 / x = 1/75

multiply .3 by 75 to get 22.5 m

Answer:

1/3 cup of ice icream

Step-by-step explanation:

This is a proportions question. Since we know that we need 1/4 cup of ice cream for every 3/4 cup of root beer, we need to find how many cups of ice cream we need for 1 cup of root bear.

We need to find out what times 3/4 makes 1. This can be done with:

(3/4)x = 1

x = 4/3

Now multiply that with 1/4 to get the amount of ice cream.

4/3 times 1/4 = 1/3

Answer:

So 2t%5E2%2B4t-30 completely factors to 2%28t%2B5%29%28t-3%29.

In other words, 2t%5E2%2B4t-30=2%28t%2B5%29%28t-3%29.

Note: you can check the answer by expanding 2%28t%2B5%29%28t-3%29 to get 2t%5E2%2B4t-30 or by graphing the original expression and the answer (the two graphs should be identical).

Answer:

That is a 45-45-90 triangle next to a 30-60-90 triangle.  

So, the height of the left triangle equals 5.

That makes the short side of the 30-60-90 triangle also equal to 5.

In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.

Therefore, the hypotenuse (or "x") equals 10.

Answer:

198 yards

Step-by-step explanation:

Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.

The total length of stings required for 66 balloons would be;

total length of balloon strings = 66 x 9 feet

                                                 = 594 feet

But the string is sold by the yard at the store.

So that,

1 yard = 36 inches = 3 feet

x yard = 594 feet

Thus,

x = [tex]\frac{594}{3}[/tex]

  = 198 yards

x = 198 yards

Therefore, the total length of string that Sean would need is 198 yards.

Answer:

6 hours

Step-by-step explanation:

Answer using slope formula:

[tex]\frac{y2-y1}{x2-x1}[/tex]

We can find the slope.

Substitute:

[tex]\frac{5-2}{2-1}[/tex]

Subtract:

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

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

Our slope is 3.

Now we will use Point Slope formula:

[tex]y-y1=m(x-x1)[/tex]

To find our equation.

I will use the first ordered pair, (1,2).

Substitute:

[tex]y-2=3(x-1)[/tex]

Your answer is C. (y − 2) = 3(x − 1).

Hope this helped! :)

Answer:

10

Step-by-step explanation:

x³=1000

x=3√1000

x=10

Answer:

x = 10   or   x = -5 + 5*i*sqrt(3)   or   x = -5 - 5*i*sqrt(3)

Step-by-step explanation:

x^3 = 1000

x^3 - 1000 = 0

(x - 10)(x^2 + 10x + 100) = 0

x = 10 or x^2 + 10x + 100 = 0

x = 10 or x^2 + 10x + 25 = -100 + 25

x = 10 or (x + 5)^2 = -75

x = 10 or x + 5 = sqrt(-75) or x + 5 = -sqrt(75)

x = 10   or   x = -5 + 5*i*sqrt(3)   or   x = -5 - 5*i*sqrt(3)

19. SSS

three proportional sides

20.The mid-segment SR of triangle, which joins the midpoints of two sides of triangle, is parallel to the third side of the triangle and half the length of that third side of the triangle.

So s the sides of triangle SFR and GFH are proportional.

21.AAA

two pairs of corresponding angles are congruent and angle B is common.

22.they are not similar because pairs of corresponding angles are not congruent.

96 is not equal to 97 also even not proportional.

23.

x=10

explanation:sides are proportional

26/13=2

so

22/2=11 and 11=2x-9 2x=11+9=20 x=20/2=10

24.

x=11

Because it is given that each pair is similar then we have proportional sides but FM=MG=20 so

LM=MK

50=4x+6

4x=44

x=11

Answer:

M = -2/5

Step-by-step explanation:

To find the slope of a line when you know two points, use the following formula.

M = y₂ - y₁ ÷ x₂ - x₁

M = 9 - 11 ÷ -12 - (-17)

M = -2 ÷ 5

M = -2/5

Answer:

Step-by-step explanation:

Depends on how many points on the graph

[tex]y=x^2-4x+6\\y'=2x-4[/tex]

To find the slope/gradient of the curve at the specific point, we use the derivative.

Then substitute x = 3 in y' = 2x-4

[tex]y'=2(3)-4\\y'=6-4\\y'=2[/tex]

Therefore, the slope/gradient of y = x²-4x+6 at (3,3) is 2.

Answer:

25.734

Step of explanation:

tanjent =opposite/adjacent

cosine =adjacent /hypotenuse

sine =opposite /hypotenuse

this use tangent because the opposite number is there and we want to find adjacent

so t =opposite /adjacent

tan25 °=12/ a

a=12/tan25

=25.734
