Tyler needs to buy a book for school that costs $13 he also wants to get a book for each of his two sisters and he wants to be sure he spends the same amount on each of their books. 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.

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

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]

Raymond had already run 3 miles on his own, and he expects to run 1 mile during each track practice. How many track practices would it take for Raymond to run 45 miles?
Answer in the number of practices.
Answer:
42
Step-by-step explanation:
45-3
Answer:
11.25, or 42
Step-by-step explanation:
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

Step-by-step explanation:
PLEASE HELP FAST!!!!!
Answer:
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.
In a game, the probability that a spinner will land on a 2 is 1/3. How many times would you expect to land on a 2 if you spin the spinner 6 times?
Answer:
2 times
Step-by-step explanation:
The probability of 1/3 means that the spinner will land on a 2, 1/3 of the time:
We can predict how many times it will land on a 2 by finding 1/3 of 6:
6/3
= 2
So, the spinner will land on a 2, two times
Number of times probability of landing on a 2 is 2, when you spin the spinner 6 times.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, in a game, the probability that a spinner will land on a 2 is 1/3.
If you spin the spinner 6 times, probability of landing on a 2 is
1/3 ×6
= 2
Therefore, number of times probability of landing on a 2 is 2.

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]

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
Nancy is making accessories for the soccer team. She uses 546.12 inches of fabric on headbands for 33 players and 3 coaches. She also uses 307.23 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
15.17in of fabric on headbands
9.31 in of fabric on wristbands.
Step-by-step explanation:
Step one:
given data
the total amount of person players plus coaches= 33+3= 36
for each person, she uses = 546.12/36= 15.17 in of fabric on headbands
She also uses 307.23 inches of fabric on wristbands for just the players
For each player, she will use= 307.23/33= 9.31 in of fabric
Hence for each player, she used
15.17in of fabric on headbands
9.31 in of fabric on wristbands
