Answer:

Below

Step-by-step explanation:

B varies directly with the cube of t so:

● B = t^3

B varies inversly as u

● B = 1/u

Let's solve the equation for u:

B= 1/u = t^3

● B= 1/u

Switch u and B

● u = 1/B = 1/t^3

If u is 1 then b and t are also 1.

Step-by-step explanation:

First we need to find out how many miles we can travel using 1 gallon of gasoline. We can easily find that by dividing 78/13 which equals 6. Now we just need to multiply all of the given answers by 6. To be reasonable, since we already know 13*6=78, we should look at the next smallest number and go up from there.

The next smallest number given is 25. 25*6=150.

Answer:

The arc measure, x, that the satellite can see is 160°

Step-by-step explanation:

Given that the two tangents intersect at a point outside the with circle center O

The angle formed between between the two tangent = 20°

The first arc formed is measured as x°, which is the arc opposite the point where the two tangents meet = The arc the satellite can see

The angle x is given by the relationship;

x = 2 × (90 - v/2)

Where;

v = The angle formed at the point where the two tangent meet = 20°

Therefore;

x = 2 × (90 - 20/2) =  2 × (90 - 10) =  2 × 80  = 160°

The arc measure, x, that the satellite can see = 160°.

Answer: C. 35 square centimeters

Think of cutting a cube along the opposite diagonals (the diagonals on the opposite faces). The resulting area that is inside is the cross sectional area. It is a rectangle with sides of 5 and 7. The 7 is approximate as it is the length of the diagonal. So we have 5*7 = 35 as the approximate cross sectional area.

Answer:

x= 20

Step-by-step explanation:

The three angles add to 90 degrees

x+2x+x+10 = 90

Combine like terms

4x+10 = 90

Subtract 10 from each side

4x +10-10 = 90-10

4x = 80

Divide by 4

4x/4 = 80/4

x = 20

Answer:

x = 20

Step-by-step explanation:

The three angles are complementary to each other.

That means they add up to 90 degrees.

x + 2x + (x + 10) = 90

Combine like terms.

4x + 10 = 90

Subtract 10 on both sides.

4x = 80

Divide both sides by 4.

x = 20

Distance traveled by Mike in 12 hours = 4 * 12 = 48 km

This will become the radius of the circle

r = 48 km

Area of the circle to be searched = πr²

                                                       = 3.14 * 48 * 48

                                                       = 7234.56 square km

Step-by-step explanation:

f(x) = (x − 1)(x + 3)(x − 3)

This functions has 3 zeros as 1 ,-3, and 3

Lets evaluate the function at 0

f(0)  = (0 − 1)(0 + 3)(0 − 3) = -1 * 3 * -3 = 9

f(2)  = (2 − 1)(2 + 3)(2 − 3) = 1 * 5 * -1 = -5

Hey there!

2/3% is basically 2/3's of 1 percent.

Thus, as a fraction we get 2/300.

Hope this helps :)

Answer:

1/150

Step-by-step explanation:

2/3%

We know that 1% = 1/100

2/3% = (2/3)/100

2/3% = 2/(3 × 100)

2/3% = 2/300

2/3% = 1/150

Step-by-step explanation:

Garden roller is in the shape of cylinder.

So, one revolution =  Curved surface area of the cylinder

diameter  = 70 cm

radius = 70/2 = 35 cm

h = 100 cm

Curved surface area of the cylinder = 2πrh

                                                           = [tex]2*\frac{22}{7}*35*100[/tex]

                                                           = 22000 square cm

Area covered in 15 revolutions = 15 * 22000

                                                    = 330000 square cm

2) Coin

diameter = 22 mm

r = 22/2 = 11 mm

Volume of coin = 66 mm

πr²h = 66

[tex]\frac{22}{7}*11*11*h=66\\\\\\h=\frac{66*7}{11*11*22}\\h=0.17 mm[/tex]

It will take 33.33 years to double his money.

We have roger who inherited $5000 from his father who invested the money in an account bearing 6% annual interest.

We have to find out how long it would take for this inheritance to double in value.

The formula to calculate the Simple Interest on a given amount of principal money (x) at the rate of (r%) for a given amount of time (t) is -

[tex]SI =\frac{x \times r \times t}{100}[/tex]

In the question given : Simple Interest = 2 x Principal = 2[tex]x[/tex]

Hence, the equation becomes -

[tex]2x =\frac{x\times r\times t}{100} \\\\t = \frac{200}{r} \\\\t = \frac{200}{6} \\[/tex]

t = 33.33 years

Hence, it will take 33.33 years to double his money.

Step-by-step explanation:

If we know that the temperature fell 4 degrees in [tex]\frac{3}{4}[/tex] of an hour, we can set up a proportion to see how much fell in an hour.

[tex]\frac{4}{0.75} = \frac{x}{1}[/tex]

The correct answer is all real numbers x, except x=o.

Step-by-step explanation:

To calculate the domain, we will "remove" from the equation those values that make it impossible to perform any mathematical operation.

In a rational function the denominator must be different from zero, since we need a set of values that do not cancel the denominator.

That is why the domain can include any real number, except 0. Remember that real numbers are any number that corresponds to a point on the real line and can be classified into natural, integers, rational and irrational numbers. In other words, any real number is between minus infinity and infinity and we can represent it on the real line.

Answer:

450 m²

Step-by-step explanation:

The formula for area of a rectangle is A = lw.  You are given the length (30 m) and the width (15 m).  Plug in the numbers and solve for A.

A = lw

A = (30 m)(15 m)

A = 450 m²

Answer:

d. 72 in³

Step-by-step explanation:

To find the volume of  a cylinder that a cone of volume 24 cubic inches fits in exactly inside of, we will follow the steps below:

From the question volume of the cone = 24 cubic inches

volume of a cone = [tex]\frac{1}{3}[/tex] πr²h

and volume of a cylinder = πr²h

This implies

volume of a cone = [tex]\frac{1}{3}[/tex] πr²h

                            = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

volume of a cone =  [tex]\frac{1}{3}[/tex] (volume of a cylinder)

24  =  [tex]\frac{1}{3}[/tex] (volume of a cylinder)

multiply both-side of the equation by 3

24×3 =   [tex]\frac{1}{3}[/tex] (volume of a cylinder)

72  =volume of a cylinder

Therefore volume of the cylinder that the cone fits exactly inside of is  72 cubic inches

Answer:

1)  2/3 is 400% of 1/6

2) 0.2 is 12.5% of 1 3/5

Step-by-step explanation:

1) First, let's switch these two fractions to a low common denominator. I used sixths, and got 4/6 and 1/6. then, noticing that 4/6 is 4x bigger than 1/6, and 100% means all of the 1/6, and 4/6 is 4x that, 4x 100% is 400%, that's the answer ;-)

2) First, let's convert these both to fractions, 1/5 and 1 3/5, which converts to 8/5. 8/5 is 8x as much as 1/5, which means that it is 12.5%

Answer:

14.9

Step-by-step explanation:

Given

149

Required

Scale factor of ⅒

The result of a scale factor is the product of an expression by its scale factor.

The result of 149 scale factor of 10 is the product of 149 by 10

In other words;

149 * ⅒

= (149 * 1)/10

= (149)/10

Remove bracket

= 149/10

= 14.9

Hence, 149 scaled down by a factor of ⅒ is 14.9
