Write 180 grams as a percentage of 1 kilogram
Answer:
18%
Step-by-step explanation:
There are 1000 grams to a kilogram, so to find the percentage of a kilogram, simply divide by 1000.
180 ÷ 1000 = 0.18 kilograms (or 18%)
Answer
18%
Step-by-step explanation:
One kilogram is a thousand grams and one gram is .1% of one kilogram. So 180 grams would be 18.0% kilograms
(but you can drop the zero to 18%)

Answer:
Not sure, might 360 degrees
Step-by-step explanation:
straight angles are 180%, and the sum of the angles in a triangle are 180.
3 times 180= 540 (technically you don't need to know that)
3-1=2, and 2*180=360

Prove that:
7^16+7^
14 is divisible by 50.
Answer:
See Explanation
Answer: [tex] \boxed{ {7}^{14}} .50[/tex]
Step-by-step explanation:
[tex]{7}^{16} + {7}^{14} \\ \\ = {7}^{14} ( {7}^{2} + 1) \\ \\ = {7}^{14} (49 + 1) \\ \\ = {7}^{14}.50[/tex]
Since, one factor of [tex] {7}^{16}+ {7}^{14}[/tex] is 50.
Therefore, [tex] {7}^{16}+ {7}^{14}[/tex] is divisible by 50.
Hence proved.
A medical insurance company offers two prescription-drug insurance plans. With plan 1, James would pay the first $150 of his prescription costs and 50% of all costs after that. With plan 2, James would pay the first $280 of costs, but only 20% of the rest. For what amount of prescription costs will plan 2 save James money? (Assume that his prescription costs exceed $280.) mostly need help on how to do the problem
Answer:
when expenses are greater than $433.33
Step-by-step explanation:
set up equations for each plan
let 'x' = prescription costs
Plan 1: y = 150 + .5x
Plan 2: y = 280 + .2x
150 + .5x = 280 + .2x
.5x = 130 + .2x
.3x = 130
x = 433.33
i checked my answer by graphing each equation and $433.33 is the break-even point where each plan would have the same costs but, after that, the expenses for Plan B are less

David is playing basketball and makes 3 of his 5 shots. What is the experimental probability he will make his next shot?
Answer:
We have to divide 3/5 which is 0.6 or 60% chance
Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
First you put into fraction form. 3 out of the 5 shots is 3/5.
Now you divide 3 by 5 to get 0.6
then you would multiply 0.6 by 100 to get 60 and that would be your percentage.

Three books cost $18.75. How much would 8 books cost?
Answer:
$50
Step-by-step explanation:
Create a proportion where x is the cost of 8 books:
[tex]\frac{3}{18.75}[/tex] = [tex]\frac{8}{x}[/tex]
Cross multiply and solve for x:
3x = 150
x = 50
So, 8 books would cost $50
Answer: $50
Step-by-step explanation:
$18.75 divided by 3 = $6.25
$6.25 times 8 = $50

If a six-sided die is rolled 5 times, what is the probability of rolling numbers less than 3 ?
Distributions of probabilities help to model our world, allowing us to estimate the likelihood of a said event or to approximate the variability of incidence. It is a common way of describing the probability of an event as well as possibly forecasting it, and the further calculation can be defined as follows:
The possibility of rolling a six on a 6-sided die is [tex]\frac{1}{6}[/tex]. There are
Three 6's are therefore [tex]\binom{1}{6}^3[/tex] likely to roll.
The probability that you don't roll a 6 is [tex]\binom{5}{6}[/tex] and you are not 6 double the record is[tex]\binom{5}{6}^2[/tex].
In 5 tests, there are 10 different ways [tex]\binom{5}{3}=10[/tex] to rolle three 6s.
Then we all have together:
[tex]\to 10 \times \binom{1}{6}^3 \times \binom{5}{6}^2 \approx 0.0322[/tex]
Therefore, the final answer is "0.0322".

An equation for the line whose slope is 5 and which passes through the point ( –2, 11)
The required equation of the line whose slope is 5 and passes through the point (-2, 11) is (y - 11) = 5(x+2) or y = 5x + 21.
An equation for the line whose slope is 5 and which passes through the point ( –2, 11) is to determined.
A line can be defined by the shortest distance between two points is called a line. The standard equation of the line is y =mx + c, where m and c are the slope and y-intercept of the line respectively.
Slope ( m ) = 5 and an ordered pair ( -2 , 11 ) is given in question
Equation of line is given as
[tex]y-y_1= m(x-x_1)\\[/tex]
y - 11 = 5 (x + 2)
y - 11 = 5x + 10
y = 5x + 10 +11
y = 5x + 21
Thus, the required equation of the line whose slope is 5 and passes through the point (-2, 11) is (y - 11) = 5(x+2) or y = 5x + 21.

What is the area of the paper used to wrap a can of soup if the can is 11 cm tall and has a diameter of 7.5 cm. Show all formulas and work.
Notice that a can is a cylinder, which is basically two circles and one rectangle. Now, the question wants area of this rectangle.
You know the width of the rectangle (or the paper), which is 11cm. How do you find the length then?
Notice that the length of the rectangle is also the circumference of the circles. From here, use C = πd where C is circumference and d is diameter. The d is given, which is 7.5 cm. Depending on the question, π can be 3.14, 22/7 or the actual pi.
multiply π and 7.5cm and you get the circumference. Multiply this to 11cm and you get area of the rectangle.
