Can you please help me with this. -9m-86=-75+2m
Answer:
m = - 1
Step-by-step explanation:
Given
- 9m - 86 = - 75 + 2m ( subtract 2m from both sides )
- 11m - 86 = - 75 ( add 86 to both sides )
- 11m = 11 ( divide both sides by - 11 )
m = - 1
What is the length of ABC?
Please help!.!.!
I’ll give Brainliest to whoever answers first!
All of them are the same length because if you see the picture the red dot is in the middle of the circle so that's how there all the same length.
Step-by-step explanation:
Circumference of the circle
= 2πr = (2)(π)(12 in) = 24π in.
Length of arc ABC
= 24π in * (210°/360°)
= 14π in
= 43.98 in.
The price of an item has been reduced by 20%. The original price was $55. What is the price of the item now?
Answer:
The price is now $44
Step-by-step explanation:
The original price is $55
The discount percent is20%
Calculate the savings: 20% of $55 = $11
Subtract the savings from the original price to get the sale price: $55 - $11 = $44

Answer:
11. x = 3 and BC = 8.
Step-by-step explanation:
FA = 2BC so
3x + 7 = 2(3x - 1)
3x + 7 = 6x - 2
-3x = -9
x = 3
and BC = 3(3) - 1 = 8.

Simplify the expression to a form in which 2 is raised to a single integer power. fraction numerator open parentheses 2 to the power of 10 close parentheses cubed 2 to the power of short dash 10 end exponent over denominator 2 to the power of short dash 7 end exponent end fraction
Answer:
2^27
Step-by-step explanation:
Given the following expression:
[(2^10)^3 x (2^-10)] ÷ 2^-7
This can be easily simplified. Let us simplify the numerator first. To do that, we have
(2^10)^3 making use of the power rule of indices that says:
(A^a)^b = A^ab where a and b are powers, we have:
2^(10x3) = 2^30
Therefore the numerator becomes:
2^30 x 2^-10. Also making use of the multiplication rule that says:
A^a x A^b = A^(a + b), we have
2^30 x 2^-10 = 2^(30 – 10) = 2^20.
Now we have:
(2^20) ÷ (2^-7)
To simplify this, we need the division rule of indices which says:
A^a ÷ A^b = A^(a – b)
Therefore we have:
(2^20) ÷ (2^-7) = 2^[20 – (–7)] = 2^(20+7) = 2^27
Following are the solution to the given expression:
Given:
[tex]\to \frac{[(2^{10})^3 \times (2^{-10})]}{2^{-7}}[/tex]
To find:
value=?
Solution:
[tex]\to \frac{[(2^{10})^3 \times (2^{-10})]}{2^{-7}}[/tex]
Using formula:
[tex]\to (A^a)^b = A^{ab}\\\\\to A^a \div A^b = A^{(a - b)}[/tex]
Solve the equation:
[tex]\to \frac{[(2^{30}) \times (2^{-10})]}{2^{-7}} \\\\\to \frac{(2^{30})}{2^{-7}} \times \frac{(2^{-10})}{2^{-7}} \\\\ \to \frac{(2^{30})}{2^{-7}} \times \frac{(2^{-10})}{2^{-7}} \\\\\to (2^{30 - (-7)}) \times (2^{-10- (-7)}) \\\\\to 2^{37} \times 2^{-3} \\\\\to 2^{37 -3} \\\\\to 2^{34} \\\\[/tex]
Therefore, the final answer is "[tex]\bold{2^{34}}[/tex]".

The probability of rolling a number less than 3 on a number cube is Jennifer rolls a
number cube 60 times.
How many times should Jennifer expect to roll a number less than 3?
A 10
Question:
The probability of rolling a number less than 3 on a number cube is 2/6 . Jennifer rolls a number cube 60 times. How many times should Jennifer expect to roll a number less than 3?
Answer:
The expected value is 20
Step-by-step explanation:
Given
[tex]n= 60[/tex] --- Number of rolls
[tex]p = \frac{2}{6}[/tex] -- probability
Required
Determine the expected value
Expected value (E(x)) is calculated using:
[tex]E(x) = n * p[/tex]
Substitute values for n and p
[tex]E(x) = 60 * \frac{2}{6}[/tex]
[tex]E(x) = \frac{120}{6}[/tex]
[tex]E(x) = 20[/tex]

Find an nth-degree polynomial function with real coefficients satisfying the given conditions. n = 3; 4 and 2 *i* are zeros; f(2) = -16
9514 1404 393
Answer:
f(x) = x^3 -4x^2 +4x -16
Step-by-step explanation:
If 2i is a zero, then its conjugate, -2i, is also a zero. When p is a zero, then (x-p) is a factor. For the three given zeros, the factors are ...
f(x) = (x -4)(x -2i)(x +2i)
f(x) = (x -4)(x^2 +4)
f(x) = x^3 -4x^2 +4x -16 . . . . . . multiplied out to standard form
Now, f(2) = (2 -4)(2^2 +4) = (-2)(8) = -16. This is the required value, so we're done.*
f(x) = x^3 -4x^2 +4x -16
_____
* If the required value were something else, then we would have to multiply the f(x) we found by some factor to make the value of f(2) come out right. That factor would be ...
k = (desired f(2))/(f(2) for our function so far)
In this case, ...
k = -16/-16 = 1
A store increases the price of a sweater from $20 to $22.
What is the percent of increase?
1. 0.1
2. 0.1
3. 2
4. 9
5. 10
6. 20
The percent of increase is 10% or 5. If you multiply 20 x 0.1, you get 2. Then, you add 20 and 2 together to result with $22. Therefore, the answer is 10% or a 10% increase.

What’s the proportion
Answer:
10/k=8/4
10*4=8k
K=40/8
K=5
Hey there!
“10 / k = 8 / 4”
FIRST: CROSS MULTIPLY
10(8) = 4(k)
10(8) = 80
4(k) = 4k
NEW EQUATION: 80 = 4k
SECOND: FLIP/TURN the EQUATION
4k = 80
THIRD: DIVIDE both SIDES by 4
4k / 4 = 80 / 4
CANCEL: 4 / 4 because that gives you 1
KEEP: 80 / 4 because that gives you the value of k
NEW EQUATION: 80 / 4 = v ; v = 80 / 4
FOURTH: SOLVE above and you have the k-value
Answer:
k = 5☑️

Explain why the area of a rectangle increases by a factor of 4 when the side length is doubled
The explanation behind the area of a rectangle increases by a factor of 4 when the side length is doubled is due to the fact that;
The length and width are double which translates to a product of 4 which means the area will increase by a factor of 4.
We know that area of a rectangle is;
A = length x width
Now, let us say we have a sample rectangle with length of 7 cm and width of 3 cm.
This means area is; A = 7 x 3 = 21 cm²
Now, if we double the side lengths, it means our length is now 7 x 2 = 14 cm² and width now 3 x 2 = 6
Our new area is now 14 x 6 = 84 cm²
If we look at the initial area we will see that it has been increased by a factor of 4 to obtain 84.
The reason behind this is due to the fact the length and width are double which translates to a product of 4 which means the area will increase by a factor of 4.Read more at; https://brainly.in/question/7159811
