How much does Eva pay ever 3 years?

Answer:

C.

Since the square root of 20 is around 4.5, we know that ≈4.5 is almost at the half mark between 4 and 5 on the number line.

Answer:

50%

Step-by-step explanation:

there are 8 students and 4 are shorter than 65 inches.

So 4 divided by 8 = 0.5 or 50%

Answer:

7

Step-by-step explanation:

So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4

adding this all up we get 8x-7=49, so 8x = 56 or x = 7

Answer:

x=1 y=2

Step-by-step explanation:

Isolate x for 4x -y=2: X=2+y/4

Substitute x= 2+y/4

(2+y/4 )+3y=7

simplify 2+13y/4=7

Isolate y for 2+13y/4=7

y=2

Forx= 2+y/4

Substitute y = 2

x= 2+2/4

Simplify

Answer:

  (a) correct

  (b) -48 ft/s

  (c) -32 ft/s; -64 ft/s

  (d) 9.257 s

  (e) -296.216 ft/s

Step-by-step explanation:

You are given an equation of motion and asked to find velocity and time at different points in the motion. This requires you differentiate the position function to find velocity, and that you solve the position function to find the time at a particular position.

__

The coin is "dropped", so is presumed to have no initial velocity. The initial height is given as 1371 feet. Putting these values into the given equation, you have ...

  s(t) = -16t² +1371

The velocity is the derivative of this function:

  v(t) = -32t

__

The average velocity on an interval is the change in position divided by the change in time:

  (s(2) -s(1))/(2 -1) = ((-16·2² +1371) -(-16·1² +1371))/1 = -16(4 -1) = -48 . . . ft/s

(Note: the average velocity for a quadratic position function is the velocity at the midpoint of the interval: v(1.5) = -32(1.5) = -48 . . . ft/s.)

__

Use the velocity function you found in part (a) to determine the instantaneous velocity at the given times:

  v(1) = -32(1) = -32 . . . ft/s

  v(2) = -32(2) = -64 . . . ft/s

__

The coin will reach the ground when s(t) = 0. Solving for t, we find ...

  s(t) = 0

  -16t² +1371 = 0

  1371 = 16t²

  t = √(1371/16) = (√1371)/4 ≈ 9.257 . . . . seconds

__

The velocity at impact will be ...

  v(√1371/4) = -32(√1371/4) = -8√1371 ≈ -296.216 . . . ft/s

It is expected that a vowel will be spun approximately 10 times.

Spinner is divided into 6 equal sectors labeled with the alphabets A to F

We know that, the vowels in english are A, E, I, O, U.

In between A and , there are 2 vowels, A and E.

Probabilty of getting vowel in 1 spin = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex] = 0.33

The spinner is spun 30 times.

It is expected that a vowel will be spun =  0.33 × 30 times

                                                                 = 9.9 times = 10 times (approx)

x = -30

Step-by-step explanation:

-24 = 6 + x

we'll subtract 6 to get x alone:

-24 - 6 = x

-30 = x

____________

then to check, we plug it back in

-24 = 6 + (-30)

-24 = -24 true! so -30 is right :)

Answer:

-30

Step-by-step explanation:

You can backtrack to find x:

-24-6=-36

-30+6=-24

If the copy machine prints 175 pages in 5 minutes and the number of pages printed is proportional to the time in minutes , the unit rate is 35 pages per minute.

Division is the process of determining the quotient of a number. It is the process of grouping a number into equal parts using another number.

The unit rate can be determined by dividing 175 by 5

Unit rate = 175/5 = 35 pages per minute.

Answer:

Step-by-step explanation:

First find the surface area of the clyinder and find the area circles and subtract

Then find the surface area of a cone, remove the circle area and double it.

Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741

251.32741 - 50.2 - 50.2

Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734

113.09734 - 50.2 - 50.2

Total: 12.69734 + 150.92741 = 163.62475

Answer:

Question 1

The function [tex]f(x) = x + 6[/tex] is one-to-one, so it does have an inverse.

The inverse of +6 is -6, so [tex]f^{-1}(x)=x-6[/tex]

Therefore, g(x) is the inverse of f(x).

Question 2

The function [tex]f(x) = -3x -9[/tex] is one-to-one, so it does have an inverse.

To find the inverse, replace f(x) with y:

[tex]\implies y = -3x -9[/tex]

Rearrange the equation to make x the subject:

[tex]\implies y+9= -3x[/tex]

[tex]\implies x=-\dfrac13(y+9)[/tex]

[tex]\implies x=-\dfrac13y-3[/tex]

Replace x with [tex]f^{-1}(x)[/tex] and y with x:

[tex]\implies f^{-1}(x)=-\dfrac13x-3[/tex]

Therefore, g(x) is the inverse of f(x).

Answer:

$30.00

Step-by-step explanation:

The original price of the sweater is $75.00.  The new sale price is the original price of  100% less  60% of the original price.  That means the sales price is 40% of the original price.

You can do this 2 ways:

1.  $75 x 60% or .60 = $45

  $75-45 = $30

or

2.  $75 x 40% or .40 = $30

Answer:

False

Step-by-step explanation:

There's no such thing like that

The probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

f = 100 stamps in the collection

A = stamps in the 20th century

B = British stamps

We can make a linear equation to solve for x as the total stamps are 100 in the collection.

[tex]\rm x(x-6)+x+2x+32= 100\\\\\rm x^2-6x+x+2x+32 = 100\\\\\rm x^2-3x-68 = 0[/tex]

After solving x = 9.88, or x = -6.88

Probability can't be negative so neglecting the negative ones

x = 9.88

The probability that it is British:

[tex]=\rm \frac{x +2x + 32}{100}[/tex]  

[tex]=\rm \frac{9.88 +2(9.88) + 32}{100}[/tex]

= 61.64/100

= 0.6164

Thus, the probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

Answer: 190 m³

Step-by-step explanation:

    We will calculate the volume of the prisms separately, and then add them together.

V = L * W * H

   [1]

V = L * W * H

V = 9 * 2 * 5

V = 90 m³

   [2]

V = L * W * H

V = 5 * 5 * 4

V = 100 m³

   [Adding together]

100 + 90 = 190 m³

               The volume is 190 m³
