how do i evaluate exponantial numbers
Answer:
Evaluating Exponents. An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81

Which inequalities would have an open circle when graphed? Check all that apply.
t Less-than-or-equal-to 25
-2.5 Less-than-or-equal-to m
x > 5.4
One-half less-than x
x > 0
Answer:
x > 5.4
One-half less-than x
x > 0
Step-by-step explanation:
use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to"
Answer:
if they have < or > then the inequality has and open circle
if they have [tex]\leq or \geq[/tex] then the inequality has a closed circle

Convert the decimal to a fraction in simplest form:
0.333
O 533/1000
1
O 333 —
10
1
O 3 —
333
O 333/1000
Answer:
Decimal 0.333 to a fraction in simplest form is: [tex]\frac{333}{1000}[/tex]
Step-by-step explanation:
Given the decimal
[tex]0.333[/tex]
Multiply and divide by 10 for every number after the decimal point.
There are three digits to the right of the decimal point, therefore multiply and divide by 1000.
Thus,
[tex]0.333=\frac{0.333\cdot \:\:1000}{1000}[/tex]
[tex]=\frac{333}{1000}[/tex] ∵ 0.333×1000 = 333
Let us check if we can reduce the fraction [tex]\frac{333}{1000}[/tex]
For this, we need to find a common factor of 333 and 1000 in order to cancel it out.
But, first, we need to find the Greatest Common Divisor (GCD) of 333, 1000
Greatest Common Divisor (GCD) :
The GCD of a, b is the largest positive number that divides both a and b without a remainder.
Prime Factorization of 333: 3 · 3 · 37
Prime Factorization of 1000: 2 · 2 · 2 · 5 · 5 · 5
As there is no common factor for 333 and 1000, therefore, the GCD is 1.
Important Tip:
As GCD is 1, therefore the fraction can not be simplified.Therefore, decimal 0.333 to a fraction in simplest form is: [tex]\frac{333}{1000}[/tex]

Sandra bought 4 pounds of sweet potatoes for $6.28. What is the cost per pound of the sweet potatoes?
Answer:
Cost of 1 sweet potato is $6.28 divided by 4 which will give $1.75
Answer:
$1.57
Step-by-step explanation:
What we know:
- There are 4 pounds of sweet potatoes
- 4 pounds of sweet potatoes cost $6.28
To find the cost per pound of sweet potatoes, divide $6.28 by 4.
6.28 ÷ 4
= $1.57
Therefore, the cost per pound of sweet potatoes is $1.57.

MARK ME BRAINLISTThe quantities x and y are proportional. Use each of the integers 1-5 to complete the table. **CORRECT ANSWER IS GIVEN BRAINLEST POINTS**
Answer:
x 10 4 6 1
y 5 2 3 0.5
Step-by-step explanation:
You have to start with a guess and see if it works. If it works, you're done. If it doesn't work, you need to make a difference guess.
I'll start by guessing that above the 0.5 is a 1.
If that is correct, then every x value is double the y value below it.
5 goes below the 10. 3 goes below the 6. Then you have 4 and 2 left.
That is every whole number from 1 to 5. It works.
x 10 4 6 1
y 5 2 3 0.5

The variables a and b vary directly, and b=8 when a=2.
What is the direct variation equation that relates a and b?
A.
b=2a.
B.
b-4a
C
b=8a
D
b=16a
Answer: b= 4a
( This is the correct answer, which is supposed to be option b, but a negative sign was put instead of an equal sign, so you can change appropriately)
Step-by-step explanation:
Given that a and b vary directly, can be expressed as
a ∝ b
Introducing the constant of proportionality, k, we have that
a = kb
so when a= 2, b= 8 and the constant becomes
2 = k8
k = 2/8=1/ 4
a= 1/4b
Such that
b=4a

x + 3 = −x − 3
Solve for x
[tex]x = - 3[/tex]
Explanation :[tex]x + 3 = - x - 3[/tex]
[tex]x + 3 + x = - x - 3 + x[/tex]
[tex]2x + 3 = - 3[/tex]
[tex]2x = - 3 - 3[/tex]
[tex]2x = - 6[/tex]
[tex]x = - 6 \div 2[/tex]
