Step-by-step explanation:
I used the pythagorean theorem on BAC triangle
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)
The length of BC is 15 units.
In the right triangle ABC.
we have AC = 8 units and AB = 17 units.
We need to find the length of BC using the Pythagorean theorem.
What is the Pythagorean theorem?It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In the given right-angle triangle ABC.
We have,
AB = hypotenuse and the other two sides are AC and BC.
Applying the Pythagorean theorem.
We get,
[tex]AB^{2} = AC^2 +BC^2[/tex]
Now substitute AC = 8 and AB = 17.
[tex]17^2=8^2+BC^2\\289=64+BC^2\\BC^2=289-64\\BC^2=225\\BC=\sqrt{225}\\ BC=15 ~units.[/tex]
Thus, we have the length of BC as 15 units.

The evaluation of of the expression -(2⁻⁶)(2³) is - 1 / 8(-1 over 8)
How to evaluate an expression?The expression can be evaluated as follows:
-(2⁻⁶)(2³)
The expression can be evaluated using the law of indices,
[tex](x^{a} )^{b} = x^{ab}[/tex] and [tex](x^{-b} )=\frac{1}{x^{b} }[/tex]
Therefore,
-(2⁻⁶)(2³)
2⁻⁶ = 1 / 2⁶ = 1 / 64
2³ = 2 × 2 × 2 = 8
Hence,
-(1 / 64)(8) = - 8 / 64 = - 1 / 8

Why do most student loans involve a co-signer?
a.
Most students won’t be able to afford paying for their loans, and leave that responsibility to their co-signers.
b.
Co-signers were most likely college students themselves and understand what it is like to be a college student.
c.
Most students aren’t responsible enough to know much about any type of loans, so a co-signer is there to make sure everything is secure.
d.
Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.
Answers
The correct statement is Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.
What is loan?A loan is the lending of money by one or more individuals, organizations, or other entities to other individuals, organizations, etc.
Students need cosigners in order to qualify for a student loan or student loan refinance. This is because many students don't have an extensive credit history of their own. The other person cosigns the loan application so that the lender will consider their credit and income as well as yours.
Hence, Most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.

4+7a=12+8a
with steps pls
Answers
Answer:a=-8
Step-by-step explanation:
4+7a=12+8a
So first you want to have the variables on the same side
4+7a-7a=12+8a-7a
This is how you got the 7a to the right side. Then you subtract 8a-7a So the equation becomes
4=12+a
Now there are two ways of doing this.
1. 4-12=12-12+a
You moved the 12 to the left side so you have the same variable on one side
4-12=-8
So then a=-8
Or
2. 4-4=12-4+a
0=8+a
then you would have to subtract 8 to keep 'a' by itself
-8=8-8+a
simplify it
-8=a
same thing
step 1: subtract 7a from both sides.
now you have 4=12+a
step 2. subtract 12 from both sides.
now you have -8=a
the answer is a=-8

The knitting club sold 40 scarves and hats at a winter festival and made $700 from the sales. They charged $18 for each scarf and $14 for each hat.
If s represents the number of scarves sold and h represents the number of hats sold, which system of equations represents the constraints of the situation?
Group of answer choices
A. s + h =40
18s +14h = 700
B. 18s +14h =40
s + h =700
C. 40s + h +700
18s + 14h = 700
D. No answer text provided.
Answers
Answer:
A. s + h = 40 18s + 14h = 700Step-by-step explanation:
club sold 40 scarves and hats so the sum of scarves and hats is 40
s + h = 40 - one of equations
They charged $18 for each scarf and $14 for each hat so:
18×s - money made from scarves
14×h - money made from hats
18s + 14h - sum of money made from scarves and hats so:
18s + 14h = 700 - second of equatinons
The system of equations represents the constraints of the situation are s + h = 40 and 18s + 14h = 700.Option A is correct.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The system of equations is as follows,
s + h =40
18s +14h = 700

A volleyball team scored 14 more points in its first game than in its third game. In the second game, the team scored 28 points. The total number of points scored was less than 80. What is the greatest number of points the team could have scored in its first game?
Answers
Answer:
27
Step-by-step explanation:
Let the no. of points scored in third game x
given that
A volleyball team scored 14 more points in its first game than in its third game
Then
no. of points scored in First game = x + 14
no. of points scored in Second game = 28
Total no of points scored in three games = x + x + 14 + 28 = 2x + 42
given that The total number of points scored was less than 80
thus
2x + 42 < 80
2x < 80 -42
2x < 28
x < 14
now we know that x is less than
and since x is point scored it will be integer as point cannot be in fraction
and greatest integer less than 14 will be 13
Thus, greatest point scored in third game will be 13
similarly greatest number of points the team could have scored in its first game will be x + 14 = 13 + 14 = 27

What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. What can be values and units?
For example
Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Price for furniture set = $4,345
a) The sum of these monthly payments
=15×11
=$165
b) Chris pay in the last month of this plan
=4,345-165
= $4180
