What operation do we use to solve unit rate?
FAST PLEASE
Answer:
Step-by-step explanation:

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

Please help me with this math question.
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x + 4 ← is in slope- intercept form
with y- intercept c = 4 → D
At Lincoln Middle School, 1/3 of the students play a musical instrument. Of the students who play instruments, 3/4 tried out for the class play. What is the probability that a student
selected at random plays a musical instrument and tried out for the class play?
25%
33%
66%
75%
The probability that a student selected at random plays a musical instrument and tried out for the class play is 25%.
To find the probability that a student selected at random plays a musical instrument and tried out for the class play, we need to multiply the probabilities of each event happening.
Given:
Probability of a student playing a musical instrument = 1/3
Probability of a student who plays an instrument trying out for the class play = 3/4
To find the combined probability, we multiply these probabilities:
Probability = (1/3) * (3/4)
Simplifying the multiplication:
Probability = 1/4
Converting the fraction to a percentage:
Probability = 1/4 * 100% = 25%
Therefore, the probability that a student selected at random plays a musical instrument and tried out for the class play is 25%.

of a pie. What is the cost of a whole pie?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer:
$16
Step-by-step explanation:
$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:
4 x 4 = 16
And you'd get your answer, since 4/4 equals 1 whole.

Please answer correctly !!!! Will mark Brianliest !!!!!!!!!!!
Step-by-step explanation:
since they are in order points p and q are in the middle and points O and R are on the end so they say that OR=36 since you don't know the exact lengths of all of the lengths in the middle from O to R then you multiply 5,6 and 1 by x and add
5x+6x+1x=12x
so then the whole length is equal to the ratio of 12x and also 36 so set those to equal each other
12x=36
x=3
so that is just the ratio and since they are asking for the length of O to Q that means that it is just 5x+6x=OQ
11x=OQ
insert x=3
33=OQ

If the simple interest on $7,000 for 2 years is 980, then what is the interest rate?
Answer:
7%
Step-by-step explanation:
since the formula says si=ptr/100
so we have to separate r which gives us r =(i ×100)/(p×t)
now putting the values (980×100)/(7000×2)
=7
therefore the rate of interest is 7%

Algebraically find the inverse for each of the following equations
A. y = 3x-8
B. y = 1/2x+6
C. y = x+6/2
Step-by-step explanation:
A. y= 3x -8
x = 3y -8
3y = x +8
y = (x+8)/3
B x = 1/2y +6
1/2y = x-6
y = 2x - 12
C x = y + 6/2
y = x - 6/2
You start at (2, 3). You move up 6 units. Where do you end?
Answer:
(2,9)
Step-by-step explanation:
we start at the point (2,3) and moving up 6 units
when we move up or down, we are changing the value of the y-coordinate. Since we are moving up, the value of the y-coordinate increases (makes sense, if you are thinking about a graph. The further you go up, the larger the y value becomes).
However, the x-coordinate will stay the same (no instructions on moving left or right {that changes the x value}). That means the y value will increase by 6 while the x value will stay the same.
so add 6 to 3 and get 9, and add nothing to 2
therefore, the point we end on will be (2,9)

Otis has saved $18,500 so far to buy a house. He can put this amount into account that earns 5.1% simple interest, or another with 5.1% compounded annually. Which method of earning interest should he choose simpler compound and how much more interest will the account earn using that method after four years?
F. Compound interest $15,106.30
G. Simple interest $15,106.30
H. Simple interest $298.65
J. Compound interest $298.65
Answer:
J Compound interest; $298.65
Step-by-step explanation:
Interest compounding pays interest on the interest. For the same annual rate, any amount of compounding will earn more interest.
For short time periods, the effect of compounding is not great. In general, it will be a fraction of the equivalent simple interest rate. Here, the effective multiplier for annual compounding is ...
1.051^4 = 1.22024337
and the effective multiplier for simple interest is ...
1 +0.051·4 = 1.204
Then the difference in interest rate multiplier for the 4-year period is ...
1.22024337 -1.204 = 0.01614337
That fraction of the $18500 principal is $298.65.
Compound interest earns $298.65 more than simple interest in this scenario.
Hope this helps, have an amazing day!
