Aria´s height is 3 inches less than her brother´s height. her brother´s height is unknown.

Answers

Answer 1
We can not find the answer unless we have the height of the brother.
Answer 2

The answer is x-3. We don't know the brother's height, so we make it into a variable. You may pick any variable, but x is a common choice. We then subtract 3 from x, which would give us Aria's height. Since we don't know the height of the brother, we won't know Aria's height.

What are permutation and combination?

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

The question seems to be incomplete,
So this solution is standard by certain assumptions.

Let the on the board there are n number of scores listed,
So the different possible total scores could Miles get with three darts

A collection of dimes and nickels has a total value of two dollars and contains 28 coins. How many dimes are there in the collection?

A.)14 dimes

B.)8

C.)12

D.)10

Answers

You were supposed to make a system of equations and solve it by elimination. the answer is C and here’s how i solved it. I hope this helps you out and helps you understand this topic a bit more :)

Answer:

12 dimes

Step-by-step explanation:

Let :

Dime = x

Nickel = y

Dime is worth 10 cent = $0.1

Nickel is worth 5 cent = $0.05

x + y = 28 - - - (1)

0.1x + 0.05y = 2 - - - (2)

From (1)

x = 28 - y

0.1(28 - y) + 0.05y = 2

2.8 - 0.1y + 0.05y = 2

2.8 - 0.05y = 2

2.8 - 2 = 0.05y

0.8 = 0.05y

y = 0.8 / 0.05

y = 16

x = 28 - 16

x = 12

All edges of a cube are expanding at a rate of 6 centimeters per second. (a) How fast is the volume changing when each edge is 5 centimeter(s)

Answers

Answer:

(a).The volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

Step-by-step explanation:

Let x be the side of cube

[tex]\frac{dx}{dt}=6 cm/s[/tex]

We have to find the rate at which  volume of cube changing when edge is 5 cm.

We know that

Volume of cube, V=[tex]x^3[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=3x^2\frac{dx}{dt}[/tex]

Substitute the values

[tex]\frac{dV}{dt}=3(5)^2\times 6[/tex]

[tex]\frac{dV}{dt}=450 cm^3/s[/tex]

Hence, the volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

A

$1,107.50

B

$27.69



$110.75

D

$55.38

Answers

Answer:

$27.69

Step-by-step explanation:

Given

Monthly budget (See attachment)

[tex]Month = 4\ weeks[/tex]

[tex]Week = 40 \ hour[/tex]

Required

Determine the closest hourly wage

From the attachment, the monthly budget is:

[tex]Budget = \$ 4430[/tex]

First, we calculate the closest weekly earnings.

Since a month = 4 weeks.

Then

[tex]Weekly\ Earnings = \frac{\$4430}{4}[/tex]

[tex]Weekly\ Earnings = \$1107.5[/tex]

Next, we calculate the hourly earnings:

Since 1 week = 40 hour

Then

[tex]Hourly\ Earnings = \frac{\$1107.5}{40}[/tex]

[tex]Hourly\ Earnings = \$27.6875[/tex]

From the list of options, the closest is: $27.69

Hellen used a coupon she received in the mail at a local boutique that decreased her purchase of $85.20 by $12.78. Her sister used the same coupon and decreased her purchase of $63.80 by $9.57. Write the equation of a line, in the form y = mx + b, to model this linear relationship.

Answers

Answer:

y = 12665 (100⁻¹)  + b

Step-by-step explanation:

To model this relationship, you're to write the equation of a line; in the form

y = mx + b

Now let y represent the full coupon value,

mx represent the amount spent by Hellen and her sister

and b, the change that's left on the coupon.

So, the summary of Hellen's transaction is:

$85.2 became $(85.2 - 12.78) which is  =  $72.42

The summary of her sister's transaction is:

$63.8 became $(63.8 - 9.57) which is  =  $54.23

So   y - (72.42 + 54.23) = b

y - 126.65 = b

y = 126.65 + b

Separating m from x in mx, you have

y = 12665 x 1/100  + b

y = 12665 (100⁻¹)  + b

Where m = 12,665   and x = 100⁻¹

A radial saw has a blade with a 6-in radius.
Suppose that blade spins at 1000 rpm.
Find the angular speed of the blade in
rad/min.

Answers

Answer:

The angular speed of the blade is of 166.67 rad/min

Step-by-step explanation:

The velocity, is given by the following equation:

[tex]v = rw[/tex]

In which r is the radius and w is the angular speed.

We use this relation to solve this question;

We have that:

[tex]v = 1000, r = 6[/tex]. We want to find w. So

[tex]v = rw[/tex]

[tex]1000 = 6w[/tex]

[tex]w = \frac{1000}{6}[/tex]

[tex]w = 166.67[/tex]

The angular speed of the blade is of 166.67 rad/min

When Jackson moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 24 inches tall and Tree B was 36 inches tall. Each year thereafter, Tree A grew by 10 inches per year and Tree B grew by 7 inches per year. Let A represent the height of Tree A t years after being planted and let B represent the height of Tree B t years after being planted. Write an equation for each situation, in terms of t, and determine the height of both trees at the time when they have an equal height.

Answers

Answer:

For tree A: 24+10t

For tree B: 36+7t

They are at the same height at 4 years at a height of 64 inches

Step-by-step explanation:

To figure out when the trees are at the same height make the equations equal to each other and solve for T

24+10t=36+7t

Subtract 24 and 7t from both sides to get

3t=12

divide by 3 to get

t=4

This means at t=4 they are at equal height so we plug this into any of the equations

24+10*4

this is equal to 64

We can double check by plugging t=4 into the second equation

36+7*4

36+28=64
