Jim is 8 ft 9 in tall. Jane is 23.5 in tall. How many times taller than Jane is​ Jim?

Answer:

3/4 x 12/1 because if you can decorate 3/4 a cupcake per minute, you multiply 3/4 by 12 to find the total amount of cupcakes he could decorate. 3/4 x 12/1 = 9 Paul can decorate 9 cupcakes in 12 minutes.

Answer:

he can decorate 9 cupcakes in 12 mn

Step-by-step explanation:

He can decorate 3/4 of a cupcake in 1 minute

Then

He can decorate 12×(3/4) cupcakes in 12 minutes

Or

[tex]12\times\frac{3}{4} =\frac{36}{4} =9[/tex]

then he can decorate 9 cupcakes in 12mn

Answer:

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

Answer:

approximately 10 times

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)

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

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

You can combine like terms meaning (8x+14)+ (9x-5) is 17x+9

Hi!

Given:

[tex](8x+14) + (9x-5)[/tex]

As we are adding the two groups, we can safely take them out of parentheses, as none of the signs will change:

[tex]8x+14+9x-5[/tex]

Now, we can rearrange them to make it easier, placing like terms next to each other:

[tex]8x+9x+14-5[/tex]

Now, add like terms:

[tex]17x+9[/tex]

Therefore, your answer is D.

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

X=1

The equation that results if Kiran squares both sides as his first step is gotten as; x + 2 - 10√(x + 2) + 25 = 121

We want to simplify the expression;

[√(x + 2)] - 5 = 11

Squaring both sides is;

([√(x + 2)] - 5) * ([√(x + 2)] - 5) = 11 * 11

⇒ x + 2 - 10√(x + 2) + 25 = 121

Thus, the correct answer is;

x + 2 - 10√(x + 2) + 25 = 121

Answer:

SMALLEST TO GREATEST

102 mm --> 125 mm --> 10.4 cm --> 0.12 m.

Explanation:

Millimeters (mm) is smaller than centimeters (cm). Centimeters are smaller than meters (m).

And, since both 125 mm and 102 mm has the same units of measurement, 125>102.

So, 102 goes in front of 125.

And then the rest of the order is completed by comparing the units of measurement.

$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

Formula

[tex]\sf A=P\left(1+\dfrac{rt}{n}\right)[/tex]

where:

Given:

[tex]\implies \sf A=900\left(1+\dfrac{0.08 \times 60}{365}\right)[/tex]

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).
