90% of what equals 81?? Please show how you got the answer!!
Answer:
90Step-by-step explanation:
First you want to divide 81 by 90%. You do this because 81 is the number you have and 90 is the percent you have.
81/90% = 90
Doing this will get you 90. This works for all percentages too.
Also you can check your answer by reversing this.
90 × 90% = 81

A middle school football player, Bo, is just learning how to kick field goals. Currently, he only makes 1/3 of his kicks. A die is being used to simulate the result of Bo's kicks where the numbers 1 or 2 represent a made field goal the numbers 3, 4, 5, or 6 represent a missed field goal. Use the following 20 trials of rolling a fair die to answer the question.
Based on the outcomes given, what is the estimate of the probability that Bo does not make any field goals? Write your answer as a fraction
Answer:
The correct answer is 75%.
Step-by-step explanation:
If you count all the misses in each trial as one whole miss, then you will have 15 total misses which would then leave to 5 makes. Then you divided 15 by 20 which would give you a perfect 75% of him missing the field goal. So basically, your answer is 75%.

If f(x) = x^3 + 8x² + 11x-20 and x+5 is a factor of f(x), then find all of the zeros of f(x) algebraically
Answer:
The zeros are (-5,-4,-1)
Step-by-step explanation:
Since we have a linear factor, we can use the method of long division to get the other factors
What this mean is that we simply divide the polynomial by the linear expression
we have this division result as;
By dividing, we have the other factor as ;
x^2 + 3x - 4
so we simply factorize this
x^2 -x + 4x - 4
x(x-1) + 4(x-1)
(x + 4)(x-1)
So the complete factors are;
(x + 5)(x + 4)(x-1)
To get the zeros, we simply equate each of the terms to zero
and we have our answer as;
-5 , -4 , 1

By angle bisector property:
[tex] \frac{6}{x} = \frac{8}{4} \\ \\ \frac{6}{x} = 2 \\ \\ x = \frac{6}{2} \\ \\ x = 3[/tex]
The value of given triangle of x is 3.
Angle bisector theorem states that an angle bisector of a triangle divides the opposite side into two segments that are proportional to the other two sides of the triangle. An angle bisector is a ray that divides a given angle into two angles of equal measures.
We have the given triangle is:
The triangle is ABC
and divide into two parts.
Triangle ADC and Triangle CBD.
The value also given in the figure.
AB = 6
BC = 8
AD = x
DC = 4
We have to find the value of x:
By using the Angle bisector theorem :
[tex]\frac{AB}{AD} =\frac{BC}{DC}[/tex]
Plug all the values in above formula:
[tex]\frac{6}{x}=\frac{8}{4}[/tex]
=> 6/x = 2
x = 6/2
x= 3
The value of given triangle of x is 3

round 0.009 to the nearest hundredth
Answer:
0.01
Step-by-step explanation:
Rounded to the nearest hundredth 0.009 is 0.01.
The term "Rounding off" means the process of approximating a number to a specified degree of accuracy by replacing it with a neighboring value that is efficient to work with, and makes calculation easy or more meaningful in a given context. This involves reducing the number of significant digits or decimal places in a numerical value while retaining its overall magnitude.
To round off 0.009 to the nearest hundredth, 1 is added to the digit in second place after the decimal, i.e., 0, and the digit in the third place after the decimal, i,e, 9 is replaced by 0.
Thus, when rounded to the nearest 100th, 0.009 results as 0.01.

What is the equation of the line that includes the points (1,6) and (2,8)?
Answer: y = 2x + 4
Step-by-step explanation:
y = mx + b
(1,6) and (2,8)
Finding Slope:
(8 - 6) / (2 - 1)
=> 2/ 1 or 2
y = 2x + b
Finding "B":
y = 2x + b
=> 6 = 2(1) + b
=> 6 = 2 + b
=> b = 4
so y = 2x + 4

If I have 50 envelopes I put equal amounts of money in each one how much will I have at the end of 50 days
Answer:
At the end of 50 days , Amount of money = $2500x
where x is the value that added every day.
Step-by-step explanation:
Let daily amount added in 1 envelope = $x
As, we have 50 envelope,
so, daily added amount in 50 envelope = $ 50x
⇒ Each day , we add money = $ 50 x
After 50 day, it becomes $50×50x = $2500x
For example -
If we add $ 1 every day in each envelope
then ,
Total amount added in 50 envelope each day = $50×1 = $ 50
Then,
After 50 days,
Total amount = $ 50×50 = $2500
∴ we get
At the end of 50 day, total amount we have = $2500

Answer:

Step-by-step explanation:
2/3y-6=6
Combine 2/3 and y
2y/3-6=6
Move all terms not containing y to the right side of the equation :
2y/3=12
Multiply both sides of the equation by 3/2
3/2*2y/3=3/2*12
Simplify both sides
y=18
