A.-1 over 8
B. -8
C.1 over 8
D.8
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

A contractor purchases ceramic tile to remodel a kitchen floor. Each tile costs $4.00, and the adhesive and grouting material needed for the whole job costs $15.82. The contractor is charged a total of $655.82, how many ceramic tiles did the contractor purchase?
Answer:
160 tiles.
Step-by-step explanation:
First let's make an equation.
Each tile costs $4, let's make t=number of tiles.
+$15.82, and the total cost being $655.82
So ideally our equation would look like
4t+15.82=655.82
Now solve.
First, subtract 15.82 on both sides.
4t=640
Second, divide 4 on both sides to make the variable t by itself.
t=160
So, the contractor purchased 160 tiles.
Able has a younger sister and an older brother. - Able’s age can be represented by x. - Able’s sister is 4 years younger than him. - Able’s older brother is twice as old as he is. - The combined age of all three siblings is 32. How old is Able’s younger sister?
Answer:9
Step-by-step explanation:
I did the math
Given:
Able's age can be represented by x.
Able's sister is 4 years younger than him.
Able's older brother is twice as old as he is.
The combined age of all three siblings is 32.
To find:
The age of Able's younger sister.
Solution:
Able's age can be represented by x.
Able's sister is 4 years younger than him.
Age of Able's sister = (x-4)
Able's older brother is twice as old as he is.
Age of Able's older brother = 2x
The combined age of all three siblings is 32.
Add 4 on both sides.
Divide both sides by 4.
The age of Able is 9 years. So, age of his younger sister is
Therefore, the age of Able's sister is 5 years.

16) 12a² - 3 |b| + 2a ; a = -5, b = -2
12(-5)² - 3 |-2| + 2(-5)
= 12(25) - 3(2) - 10
= 300 - 6 - 10
= 294 - 10
= 284
17) 4(k + 5) = -2(9k - 4)
4k + 20 = -18k + 8 Distributed 4 and -2
22k + 20 = 8 Added 18k to both sides
22k = -12 Subtracted 20 from both sides
k = -12/22 Divided 21 from both sides
k = -6/11 Simplified (GCF = 2)
18) V = π r²h
V/(π r²) = h Divided π r² from both sides
19) v = s² + (1/2)sh
v - s² = (1/2)sh Subtracted s² from both sides
2(v - s²) = sh Multiplied both sides by 2
2(v - s²)/s = h Divided s from both sides
1 2 3
subtract s² X
divide by s X
multiply by 2 X
20) F = (9/5)C + 32 ; F = 91
91 = (9/5)C + 32

295 = 9C Multiplied both sides by 5
32.8 = C Divided 9 from both sides
33 = C Rounded to the nearest whole number
21) Perimeter (P) = 2Length (L) + 2width (w)

120 = 10w + 2w
120 = 12w

What is 2/3 divided by 4/5?
Answer:
5/6
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
Answer:
5/6
Step-by-step explanation:
Keep the first fraction the same, then flip the second fraction, then multiply
2/3 * 5/4

Explain why the solution set of the inequality |x|<5 is the intersection of two sets, while the solution set of the inequality |x|>5 is the union of two sets.The solution of |x|<5 is the set of numbers that makes either of two inequalities true. The solution set of |x|>5 is the set of numbers that makes both of two inequalities true. The solution of |x|<5 is the set of numbers between −5 and 5. The solution set of |x|>5 is the set of numbers greater than 5. The solution of |x|<5 is the set of numbers that makes both of two inequalities true. The solution of |x|>5 is the set of numbers that makes either of two inequalities true. The solution of |x|<5 is the set of numbers less than −5. The solution of |x|>5 is the set of numbers between −5 and 5.
Answer:
The region of the [tex]|x|<5[/tex] is the common area between -5 and 5.
But there is no common area for the solution of [tex]|x|>5[/tex].
Step-by-step explanation:
Given two modulus functions:
[tex]1.\ |x|<5\\2.\ |x|>5[/tex]
Let us have a look at the definition of modulus function first:
[tex]|x|=\left \{ {-{x}\ if\ x<0 \atop {x}\ if\ x>0} \right.[/tex]
Now, solving the above given modulus functions one by one using the definition of modulus function.
Solution 1 :
[tex]\pm x <5\\\Rightarrow x<5, -x<5\\OR\\\Rightarrow x<5, x>-5[/tex]
Kindly refer to the attached diagram for solution.
The area shaded in the green color shows the solution for this equation.
Solution 2 :
[tex]\pm x >5\\\Rightarrow x>5, -x>5\\OR\\\Rightarrow x>5, x<-5[/tex]
Kindly refer to the attached diagram for solution.
The area shaded in the blue color shows the solution for this equation.
We can clearly observe that the region of the first equation is the common area between -5 and 5.
But there is no common area for the solution of the second equation.
Therefore, solution of [tex]|x|<5[/tex] has intersection and
solution of [tex]|x|>5[/tex] has union.
Answer:
The solution of |x|<5 is the set of numbers that makes both of two inequalities true. The solution of |x|>5 is the set of numbers that makes either of two inequalities true.

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?
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

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.
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
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
