Answer:
she has 15 boxes of pencils
Step-by-step explanation:
if we have 90 total pencils that need to be split into groups of 6, the way to find how many groups there are is by dividing 90/6, which gives you 15 groups or, in this case, 15 boxes. and you can check your work by multiply the 15 boxes by the 6 pencils in each box, which gives you 90 pencils total, so you're all good!

3x + 8 = 44
Show your work using the sketch feature and input your
solution below.
Answer:
x= 12
Step-by-step explanation
3x+8=44
subtract 8 from both sides: 3x+8= 44
-8 -8
3x=36
then divide by 3 on both sides
3x=36
3 3
which leaves : x=12

A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?
Answer:
$171
Step-by-step explanation:
A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?
Let x represent the original price of the pair of pants
From the question, we know that:
10% of x = $17.10
10/100 × x = $17.10
10x/100 = $17.10
Cross Multiply
10x = 100 × $17.10
10x = 1710
x = 1710/10
x = $171
Hence, the original price of the pants = $171

If 3 miles every practice too, then:
3+1 = 4
45/4 = 11.25
If 3 miles already, then always 1 mile:
45 - 3 = 42
42/1 = 42

A submarine is descending to examine the seafloor 2,100 feet below the surface. It took the submarine 8.75 hours to reach the seafloor. What is the submarines rate of descent in feet per hour?
Answer:
240 feet per hour
Step-by-step explanation:
Given that:
Submarine is descending for examining the sea floor.
Distance of sea floor from the surface = 2100 feet
Time taken for the descend = 8.75 hours
To find:
The rate of descent in feet per hour = ?
Solution:
Here, we are given the distance traveled in feet and the time taken to travel that distance in hours.
And we have to find nothing but the speed of the submarine.
First of all, let us have a look at the relationship among speed, distance and time.
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Putting the values of distance and time.
[tex]Speed = \dfrac{2100}{8.75}\\\Rightarrow Speed = \bold{240\ feet/hr}[/tex]

Given
f(x) = 1/9x + 2Let the inverse be y= f⁻¹(x)
To find inverse change x ⇒ y and solve for y:
x = 1/9y + 29x = y + 18y = 9x - 18So the inverse is:

What is the product of 2(cos(45°) + i sin(45°)) and 5(cos(30°) + i sin(30°))?
Pls help
Answer:
[tex]10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)[/tex]
Step-by-step explanation:
Complex Numbers
Complex numbers can be expressed in several forms. One of them is the rectangular form(x,y):
[tex]Z = x+\mathbf{i}y[/tex]
Where
[tex]\mathbf{i}=\sqrt{-1}[/tex]
They can also be expressed in polar form (r,θ):
[tex]Z=r(\cos\theta+\mathbf{i}\sin\theta)[/tex]
The polar form is also shortened to:
[tex]Z = r CiS(\theta)[/tex]
The product of two complex numbers in polar form is:
[tex][r_1Cis(\theta_1)]\cdot [r_2Cis(\theta_2)]=r_1\cdot r_2Cis(\theta_1+\theta_2)[/tex]
We are given the complex numbers:
2(cos(45°) + i sin(45°)) and 5(cos(30°) + i sin(30°))
They can be written as:
2CiS(45°) and 5CiS(30°). The product is:
2CiS(45°) * 5CiS(30°) = 10CiS(75°)
Expressing back in rectangular form:
[tex]\boxed{2CiS(45^\circ) \cdot 5CiS(30^\circ) =10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)}[/tex]

He only has $27 to spend. Let b represent the amount he can spend on each additional book
Answer:
[tex]b = \$7[/tex]
Step-by-step explanation:
Given that:
Cost of book that Tyler wants to buy for his school = $13
He wants to buy books for his sisters as well.
Total amount of money present with Tyler = $27
Money to be spent on books for his sisters is same and is represented as [tex]b[/tex].
To find:
The value of [tex]b[/tex].
Solution:
As per question statement, the sum of all the books bought must be equal to $27.
The sum of money spent on all the books = Cost of Tyler's book + Cost of books for his sisters
[tex]\Rightarrow \$13 + b + b = \$27\\\Rightarrow \$13 + 2b = \$27\\\Rightarrow 2b =\$14\\\Rightarrow b =\$7[/tex]
Therefore, Tyler must spend $7 on each of her sister's books.

Beth was working at the grocery store, in the quick check-out line. A customer bought cereal for $3.29 and milk for $3.45. The customer paid with $10.00. How much change does Beth need to give the customer?
Answer:
Change = $3.26
Step-by-step explanation:
Given the following data;
Cost of cereal = $3.29.
Cost of milk = $3.45.
Amount paid = $10.00
Total cost of items bought = $3.29 + $3.45 = $6.74
Change = Amount paid - Total cost of items purchased.
Substituting into the equation, we have;
Change = $10.00 - $6.74
Change = $3.26
Therefore, Beth need to give the customer a change of $3.26.

what is the answer to the question?
Answer:
Given : PQ = RQ
to find : angle B
PQ = RQAngle B = angle QRP ( angle opposite to equal side are equal). ...(1)angle QRP + 140° = 180° ( linear pair)angle QRP = 180° - 140°angle QRP = 40°from equation (1) Angle B = angle QRP = 40°Answer:
b=40
Step-by-step explanation:
PQ=RQ
That means both sides are the same length which also means they both have the same angel measure of 140.
A super easy way to solve this would be to realize that where p is, the angel is 140.
A straight line is 180.
b and 140 are supplementary angels. [which means they equal 180]
To find b you can make an equation.
b+140=180
or
180-140=b
I'll show you both.
First one you would subtract 140 on both sides to get the variable alone, leaving you with b=40.
For the second one, you just do 180-140 and it also equals 40.
Either way it leaves you with b=40
If you need any more help with angels and whatnot, don't be afraid to reach out. I hope that helps! <3

The solution of the system of equations be:
[tex]x=8,\:y=4[/tex]
Hence, option C is true.
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}4x+7y=60\\ -4x+7y=-4\end{bmatrix}[/tex]
adding both the equations
[tex]-4x+7y=-4[/tex]
[tex]+[/tex]
[tex]\underline{4x+7y=60}[/tex]
[tex]14y=56[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}4x+7y=60\\ 14y=56\end{bmatrix}[/tex]
solve 14y for y
[tex]14y=56[/tex]
Divide both sides by 14
[tex]\frac{14y}{14}=\frac{56}{14}[/tex]
Simplify
[tex]y=4[/tex]
[tex]\mathrm{For\:}4x+7y=60\mathrm{\:plug\:in\:}y=4[/tex]
[tex]4x+7\cdot \:4=60[/tex]
[tex]4x+28=60[/tex]
Subtract 28 from both sides
[tex]4x+28-28=60-28[/tex]
Simplify
[tex]4x=32[/tex]
Divide both sides by 4
[tex]\frac{4x}{4}=\frac{32}{4}[/tex]
[tex]x=8[/tex]
Therefore, the solution of the system of equations be:
[tex]x=8,\:y=4[/tex]
Hence, option C is true.

We conclude that:
f(2) = -5Step-by-step explanation:
Given the function
[tex]y = f(x)[/tex]
In order to determine the value f(2), we need to check the value of y at x = 2.
In other words, we need to check:
at x = 2, what is the value of y?
From the graph, it is clear that at x = 2, the value of y = -5
In other words,
f(2) = -5
Therefore, we conclude that:
f(2) = -5
