Answer:
C $80
Step-by-step explanation:
Since
80-40-20-10=150
A, B, and C are polynomials, where A = n, B = 2n + 6, and C = n2 – 1. What is AB – C in simplest form?
–n2 + 3n + 5
n2 + 6n + 1
2n2 + 6n – 1
3n2 + 5
Answer:
n^2 + 6n + 1
Step-by-step explanation:
Firstly, we have to evaluate AB
What we have to do is to multiply A and B
We have this as;
n(2n + 6) = 2n^2 + 6n
Now, we have to subtract the value of C from here and that is;
(2n^2 + 6n) - (n^2 - 1)
2n^2 + 6n - n^2 + 1
= 2n^2 -n^2 + 6n + 1
= n^2 + 6n + 1

B

formula for the area of this triangle?
The hypotenuse of a right triangle measures 18 cm and one of its legs measures 9 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
about 15.6cm.
Step-by-step explanation:
I got my answer of 15.6cm because I did the Pythagorean theorem.
a^2+b^2=c^2
The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.
Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.
In conclusion, the measure of the other leg is about 15.6cm.

Answer:
Step-by-step explanation:
Total weight of the barricade is 310 kg using 8 boxes of books
Each box of books weighs 30 kg
We need to determinethe weight of the table in order write the proper equation
Total wieght of the barricade = Table Weight + Book Weight
solving for Table Weight substract Book Weight from both sides
Total wieght of the barricade - Book Weight = Table Weight
310 - 8(30) = Table Weight
310 - 240 = Table Weight
70 = Table Weight
Total wieght of the barricade = Table Weight + Book Weight
W = 70 + 30x where x is the number of boxes
which ordered pair is a solution of the inequality y > 13x + 3
Answer:
x<y-3/13
Step-by-step explanation:
Switch sides'
13x+3<y
Subtract 3 from both sides
13x+3-3<y-3
Simplify
13x<y-3
Divide both sides by 13
13x/13<y/13-3/13
Simplify
x<y-3/13

Arianna's service charge at the beauty salon was $82.50 before tax. The sales tax rate was 8%. If she added 20% of the amount before tax as a tip, how much did she pay for the service at the salon?
Answer:
$105.60
Step-by-step explanation:
8% of $82.50 is $6.60
20% of $82.50 is $16.50
$82.50 + $6.60 + $16.50 = $105.60
Which inequality describes the relationship between points A and B on the number line?
Answer:
B > A
Step-by-step explanation:
B and A are both in between 0 and 1 on a number line.
On a number line, the further right you go, the higher numerical values get, and the further left - vice versa.
Anyhow, B is further to the right, as well as closer to 1 than A is, so we can assume that B is the greater number.

a. -3
b. a+(-a)=0
c. 0
d. -a
Answer:
a. -3
Step-by-step explanation:
Two numbers are additive inverses if they add to give a sum of zero. 3 and -3 are additive inverses since 3 + (-3) = 0. So, -3 is the additive inverse of 3.

An electronics store sold 4% of the computers that were on sale.
If only 12 computers were sold, how many computers were not sold?
Answer:
288
Step-by-step explanation:
We can use a proportion to solve this problem:
4 : 100 = 12 : x
x = (12 x 100)/4 = 300 (total computers)
300 - 12 = 288

Answer:
(1) commutative property of the addition.
(2) distributive property of the multiplication and associative property of the addition.
(3) addition property of the equality.
(4) multiplication property of the equality.
Step-by-step explanation:
First we start with:
4x + 1 + x + 3 = -11
Here we use the commutative property of the sum, which says that:
A + B = B + A
So we can reorder the terms in a sum, and we can rewrite our equation as:
4*x + x + 3 + 1 = -11
Here we also used the associative property of the sum, that says that:
A + B + C = (A + B) + C = A + ( B + C)
wich means that we can perform the sum in any order we want, then we can add the 3 and the 1
4*x + x + 4 = -11
Now we use the distributive property of the multiplication, which says that:
(A + B)*C = A*C + B*C
Then we can rewrite our equation as:
(4 + 1)*x + 4 = -11
Now we solve the sum in the parentheses to get:
5*x + 4 = -11
Now we can use the addition property of the equality, we can add (-4) in both sides to get:
5*x + 4 - 4 = -11 - 4
5*x = -15
Now we can use the multiplication property of the equality, and multiply both sides by (1/5) to get:
5*x*(1/5) = -15*(1/5)
x = -5
Three quarters of a jug was filled with water. Jyoti poured out half of the water present in the jug into a glass. What part of the jug is filled now?
Answer:
1/8
Step-by-step explanation:
Initially the jug was filled three quarters that is ¾. And jyoti poured out half of the water present in the jug. We need to find out which part of jug is filled. So since half of water is taken , hence water taken = 3/4 ÷ 2 = 3/4 × 1/2 = 3/8
⇒ Water left = 3/4 - 3/8
⇒ Water left = 6 - 3/8
⇒ Water left = 1/8
Hence 1/8 parts of water is left out.Someone help.. ive been on this question for 3hrs
Eric goes to town with £15. He spends £8.50 on a new scarf.
He meets his nan who gives him £20 and tells him to take £10 of it home for his sister
Eric then sees a jumper he likes which costs £18.
If Eric buys the jumper, will he still have £10 to give it to his sister?
Show how you worked out your answer.
Answer: No he would have 8.5$
Step-by-step explanation:
15 - 8.50 = 6.50$ + 20$ = 8.5 so no he would be 1.5$ short
If Eric buys the jumper, he will not have £10 left to give to his sister.
To determine if Eric will still have £10 to give to his sister after buying the jumper, we need to calculate his remaining balance.
Initial amount Eric has = £15
Cost of the scarf = £8.50
Amount received from his nan = £20
Cost of the jumper = £18
Amount to give to his sister = £10
First, let's calculate Eric's remaining balance after buying the scarf:
Remaining balance = Initial amount - Cost of the scarf
Remaining balance = £15 - £8.50
Remaining balance = £6.50
Next, let's calculate Eric's balance after receiving money from his nan:
Total balance = Remaining balance + Amount received from nan
Total balance = £6.50 + £20
Total balance = £26.50
Now, let's check if Eric can still afford to buy the jumper:
If Eric buys the jumper:
New balance = Total balance - Cost of the jumper
New balance = £26.50 - £18
New balance = £8.50
The new balance after buying the jumper is £8.50. As we can see, this amount is less than the £10 Eric needs to give to his sister.
Therefore, if Eric buys the jumper, he will not have £10 left to give to his sister.
