Answer:

75 : 225

Step-by-step explanation:

[tex]\frac{\frac{1}{4} }{\frac{3}{4} } :\frac{75}{y}[/tex]

0.25 × y = 0.75 × 75

0.25y = 56.25

0.25y ÷ 0.25 = 56.25 ÷ 0.25

y = 225

Answer: spinning a spinner with 4 equal sections 50 times

Step-by-step explanation:

The models that one can use to simulate the outcome of guessing the correct answers to a 50-question test will be to spinn a spinner with 4 equal sections 50 times.

Flipping a coin 50 times is wrong since the coin only has two outcomes which are head and tail. Rolling a 6-sided die 50 times is also wrong.

Therefore, the correct option is B.

Step-by-step explanation:

Two congruent figures have the same shape and size.

Answer:

m = number of minutes calls

Plan A : 30 + 0.15 m

Plan B: 16 + 0.20 m

For what amount of calling do the two plans cost the same?

30 + 0.15m = 16 + 0.20m

0.05m = 14

m = 280

280 minutes of calling, the two plans cost the same

What is the cost when the two plans cost the same?

Plan A: 30 + 0.15 m = 30 + 0.15 (280)  = 72

Plan B: 16 + 0.20 m = 16 + 0.20 (280) = 72

It's cost $72 when the two plans cost the same

Answer:

634.2 m²

Step-by-step explanation:

Given:

Angle given = 37°

Radius (r) = 15 m

Required:

Area of the shaded sector

Solution:

Area of the shaded sector = θ/360 * πr²

θ = 360 - 37 = 323°

r = 15 m

Plug in the values

Area of the shaded sector = 323/360 * π * 15²

= 634.209017

≈ 634.2 m² (nearest tenth)

Answer:

Step-by-step explanation: total number of counters = 10

number of red counters= 3

number of blue counters= 2

number of green counters = 5

p(of getting a red counter) =3/10

p(of not getting a red counter) = 1-3/10= 10-3/10=7/10

Answer:

Step-by-step explanation:

The surface area of the sphere is 12.56 yd².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that a sphere is inscribed in a cube with a volume of 8. cubic yards. We need to find the surface area of the sphere,

Since the sphere is inscribed in the cube therefore the diameter of the sphere is equal to the side length of the cube,

Now, finding the side length of the cube,

We know volume of a cube = side³

Therefore,

side³ = 8

side = 2 yd

Therefore,

Diameter of the sphere = 2 yd

Radius = 1 yd

The surface area of the sphere = 4 ×  π × radius²

= 4 × 3.14 × 1²

= 12.56

Hence the surface area of the sphere is 12.56 yd²

Answer:

x=83. please look below for explanation. if anything isn't clear, please ask

Step-by-step explanation:

so complementary means adding up to 90 degrees in math. in this particular equation, you have to make sure that both (x-18) and 25 add up to 90.

if that other side is 25 degrees, the other side must be 65 because 90-25=65.

so now you have to set those equal to each other like this:

65 = (x-18)    now just solve for x

add the 18 to the other side. the -18 and +18 cancel.

x=83

so to test and to see if that is right, we can do

83-18 = 65

does 65+25 equal 90? yes

therefore, x=83

Answer:

Option (3)

Step-by-step explanation:

Volume of the cylinder = 40 ft³

Since, volume of a cylinder is given by the expression,

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

Here, r = radius of the circular base

h = Height of the cylinder

40 = [tex]\pi r^{2}h[/tex]

[tex]h=\frac{40}{\pi r^2}[/tex] ------(1)

Volume of a cone = [tex]\frac{1}{3}\pi r^{2} h[/tex]

By substituting the value of 'h' from equation (1)

Volume of the cone = [tex]\frac{1}{3}\pi r^{2}(\frac{40}{\pi r^{2} } )[/tex]

                                 = [tex]\frac{1}{3}(40)[/tex] ft³

Therefore, Option (3) will be the correct option.

Answer:

3x-10=x+4

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

IHG = 123

IHS = x + 65

SHG = x + 78

IHG = IHS + SHG

123 = x + 65 + x + 78

123 = 2x + 143

123 - 143 = 2x

-20 = 2x

-10 = x

IHS = x + 65

IHS = - 10 + 65

IHS = 55

Answer:

Step-by-step explanation:

The mean price of a gallon of gas at the five stations is $3.81. Therefore, option A is the correct answer.

In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).

Given that, Yesterday, the price of a gallon of gas at five gas stations was $3.56, $3.71, $3.62, $3.93, and $3.83, respectively.

Today each gas station raised its price by $0.08

Now, mean =(3.56+3.71+3.62+3.93+3.83+5×0.08)/5

= (18.65+0.4)/5

= 19.05/5

= $3.81

Therefore, option A is the correct answer.

Answer:

RS = 6

Step-by-step explanation:

RS² = SU*ST (secant-tangent rule)

Substitute

(x + 6)² = (x + 4 + 5)(x + 4)

(x + 6)(x + 6) = (x + 9)(x + 4)

x(x + 6) +6(x + 6) = x(x + 4) + 9(x + 4)

x² + 6x + 6x + 36 = x² + 4x + 9x + 36

x² + 12x + 36 = x² + 13x + 36

Collect like terms

x² - x² + 12x - 13x = -36 + 36

-x = 0

x = 0

✔️RS = x + 6

Plug in the value of x

RS = 0 + 6

RS = 6
