Explain how to estimate the product of 12 x 6. Use complete sentences in your answer.
WRITER
I need a written response pls not just the answer
Answer:
10×6 with 20% added = 60+12 = 72
Step-by-step explanation:
There are several ways to estimate the product of these numbers. One way is to round 12 to 10, then multiply 10×6 to get 60 as an estimate. You know this estimate is low, because you rounded down from 12 to 10. You know that a better estimate will be about 20% higher, because 12 is 20% higher than 10.
The product can be computed mentally by recognizing that 12 is 6×2, so the product will be 6²×2. Most schools have you memorize your times tables at least through 10×10, so you already know that 6² is 36. Doubling that value (to 72) gives you the value of 6×12.
Another way to estimate the product is to round 12 to 10 and 6 to 5. Again, you know each of these "stand-in" values needs to be increased by 20% to match the real values. Then the product estimate is 10×5 = 50, and you judge that to be low by 20% +20% = 40%. 40% more than 50 gives you a refined estimate of 70, but you know that, too, is low by a small amount. (Percentage changes can only be added accurately when they are very small. The true error is 44%, which is 20%+20%+(20%)(20%).)
Which expression is equivalent to −2.1+(−5.9)+(−3.7) ?
(2.1+5.9)+(−3.7)
−(2.1−5.9)+(−3.7)
(2.1+5.9+3.7)
−2.1−(5.9+3.7)
Answer:
The last one, −2.1−(5.9+3.7)
Step-by-step explanation:
−2.1+(−5.9)+(−3.7) = -2.1-5.9-3.7 = -11.7
the only expression that will come out as -11.7 is the last one
Answer:
The Answer is
-2.1 - (-5.9 + 3.7)

A manufacturer who is considering the implementation of a one-week training program for all new employees decides to test the program with the next 100 employees hired, and then compare their productivity rate to the productivity rate of new employees based on past records–a rate that is normally distributed with a mean of 60 and a standard deviation of 8. The new program needs to produce a minimum improvement of 4 to be considered worthwhile. What is the comparison distribution's standard deviation?
Answer:
0.8
Step-by-step explanation:
From the given information:
The population mean = 60
The standard deviation = 8
The sample size = 100
The sample distribution which follows a normal distribution is the set of values taken by this statistic on each sample from the same population.
The standard deviation of the comparison distribution's = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]
The standard deviation of the comparison distribution's = [tex]\dfrac{8}{\sqrt{100}}[/tex]
The standard deviation of the comparison distribution's = 8/10
The standard deviation of the comparison distribution's = 0.8

The area of the top face of a cube is 16 square inches. Use 8 of these cubes to make a rectangular
prism. What is the volume of the rectangular prism? Hint: The shape of each face of a cube is a
square.
Answer:
The volume of the rectangular prism is 512 inches³
Step-by-step explanation:
Any cube has 6 square faces
Area of any square = L × L, where L is a length of each side
The volume of the cube = L × L × L
∵ The area of the top face of a cube = 16 inches²
→ Find which number multiply by itself = 16
∵ 16 = L × L
∵ 16 = 4 × 4
∴ L = 4 inches
Let us find the volume of 1 cube
∵ The volume of the cube = L × L × L
∵ L = 4 inches
∴ The volume of each cube = 4 × 4 × 4
∴ The volume of each cube = 64 inches³
∵ We will use 8 of this cube to make a rectangular prism
→ That means the volume of the rectangular prism is 8 times
the volume of 1 cube
∴ The volume of the prism = 8 × volume of 1 cube
∵ The volume of each cube = 64 inches³
∴ The volume of the prism = 8 × 64
∴ The volume of the prism = 512 inches³
The volume of the rectangular prism is 512 inches³
Solve for n. 2 (4 + n) = 28
Answer:
n = 10
Step-by-step explanation:
=> 2(4 + n) = 28
=> 2(4) + 2(n) = 28
=> 8 + 2n = 28
=> 2n = 28 - 8
=> 2n = 20
=> n = 20/2
=> n = 10
Answer:
n = 10
Step-by-step explanation:
2(4 + n) = 28
Distribute:
(8 + 2n) = 28
Eliminate Parenthesis:
8 + 2n = 28
Cancel Out:
2n = 20
Divide:
n = 10

Carla wants to know how many batches of birdseed she can make with 1/2 cup of sunflower seeds. She puts 1/6 cup of sunflower seeds in every batch. Carla divides 1/2 by 1/6 to find the answer. She says this is the same as multiplying 1/6 by 2; explain what Carla did wrong and show the correct solution.
Answer:
she was wrong because when you divide 1/2 by 1/6 its not the same as multiplying 1/6 by 2 but you do get the same answer its just the wrong equation
Step-by-step explanation:
9514 1404 393
Answer:
Carla inverted the numerator when she should have inverted the denominator before multiplying3Step-by-step explanation:
Any division problem is the same as a multiplication problem with the multiplier being the reciprocal of the denominator. So to divide 1/2 by 1/6, we could multiply 1/2 by (1/(1/6)) = 6/1. The result would be ...
[tex]\dfrac{1}{2}\div\dfrac{1}{6}=\dfrac{1}{2}\times\dfrac{6}{1}=\dfrac{6}{2}=\boxed{3}[/tex]
__
Carla's mistake was inverting 1/2 instead of 1/6 in her solution to the problem.

If the slope of line c is given, the slope of
which other line is known?
Answer:
Line d
Step-by-step explanation:
Since, transversal b is forming equal degree of angles (95°) with lines c and d.
So, line c || line d
As we know that parallel lines have same slope.
So, If the slope of line c is given, the slope of line d is also known.

A cell phone plan costs $30 per month for unlimited calling plus $10 per GB of data used. If Alejandro can only afford for his cell phone bill to be $60 a month, how many GB’s can he use in a month, maximum? Your answer will be a whole number. *
1 point
Answer:
3 GB
Step-by-step explanation:
If the cell phone plan cost $30 per month
then subtracting this amount from $60 we have
$60 - $30 = $30
it 1 GB costs $10
therefore dividing this amount with $30
we have
$30/$10 = 3
Alejandro can only afford 3GB per month.

72 red roses, 60 pink roses, and 48 yellow roses. What is the greatest number of bouquets that the florist can make if no roses are left over?
Answer:
12 bouquets
Step-by-step explanation:
Determine what the greatest common factor is in this case...
72/12 = 6 red roses
60/12 = 5 pink roses
48/12 = 4 yellow roses
As you can see the greatest common factor is 12. Therefore the greatest number of bouquets that the florist can make if no roses are left over should be 12 bouquets.

Solve for x
8x+12=4x−16
Answer:
X= -7
Step-by-step explanation:
When you get X to one side and simplify you get -7
8x + 12 = 4 x - 16
Subtract 12 from both sides
8x = 4x - 28
Subtract 4x from both sides
4x = -28
Divide both sides by 4 to get rid of the coefficient so we know what x alone is equal to, instead of what we have currently which shows what 4 x's equals
x = -28/4
x = -7
Understanding the answer1x = - 7
One x is equal to - 7 units.
