Mike has a 32 ounce drink. He drinks 8 ounces. Select the percent of ounces Mike has left from his drink
Answer:
75%
Step-by-step explanation:
the percentage amount of the drink that mike drank is calculated by dividing the total drink by the amount drank. In this case that is 8/32 which gives us 0.25 or 25%.
In order to find the amount Mike has left you simply subtract the amount drank from the 1 as 1 is equal to 100% or the amount mike had at the begining. In this case 1-0.15= 0.75 or 75%.
OR
you can also solve this by subtracting tha amount drank by the total then dividing the remaining drink by the total amount of the drink. In this case that would look like:
32-8= 24
24/32= 0.75

Evaluate x + 23
when x=7
Answer:
30
Step-by-step explanation:
x + 23 = ?
x = 7
All we need to do is plug in x =7 to the first equation:
7 + 23 = ?
We simplify and get:
30 = ?
Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?
Answer:
14
Step-by-step explanation:
7.5x + 25 = 130
-25 -25
7.5x = 105
[tex]\frac{7.5x}{7.5}=\frac{105}{7.5}[/tex]
x = 14
Hence, she must make 14 visits in order to earn a free movie ticket.
How do I find x in this problem?
Answer:
(6-2)×180 = 720
101+154+72+123+145+x=720
595 + x = 720
x = 720-595
x= 125

A cone has volume 3. If the cone's radius is 1. what is its height?
2.87 units
The volume of a cone is found by using the formula, V = (1/3)(pi)(h)r^2
Substituting values:
3 = (1/3)(3.14)(h)(1)
2.87 = h
Select the solution(s) of log2x=1−log(x+4).
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1

Answer:
y = (3/-2)x + 4.
Step-by-step explanation:
slope intercept form is y = mx + b
1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.
2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).
3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.
Lexington and Louisville, KY are 75 miles apart. If the scale on the map is 1 cm = 5 mi, find the distance on the map between the two cities.
Answer:

select all expressions that are equal to 3•3•3•3•3
B and C are correct
Answer:
B and C
Step-by-step explanation:
3*3*3*3*3 is the same as 3 to the 5th power since there are 5 threes. And then if you put 3 to the 4th power multiplied by 3 into a calculator, you'll get the same answer.

does 9/20 and 18/30 form a proportion
Answer:
No, they don't.
Step-by-step explanation:
I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.
18 ÷ 9 = 2
30 ÷ 20 = 1.5
The quotients aren't the same. Same thing if you convert the fractions to decimals:
9 ÷ 20 = 0.45
18 ÷ 30 = 0.6
This means the two values do NOT form a proportion.
Hope this helps! Have a great day!
Answer:
No.
Step-by-step explanation:
9/20=18/30
9*30=20*18
120=360
If you would like to know how this works please do not hesitate to ask.
-4x - 6x = -20 =?
-3(2x - 3) = 33 = ?
4x + 3x + 2x = 180 = ?
Answer:
-4x-6x=-20=
x=2
-3(2x-3)=33=
x=-4
4x+3x+2x=180
x=20
Step-by-step explanation:
-4x-6x=-20
-4+(-6)=-10x
-10x=20 (divide both by 10)
x=-2 (divide by -1 to get positive)
x=2
-3(2x-3)=33
-6x+9=33
-9 . -9
-6x=24 (divide both by -6)
x=-4 (divide by -1 to make positive)
4x+3x+2x=180
(combine like terms)
9x=180 (divide both sides by 9)
x=20
