Answer:
6(4d + 5)(4d - 5)
Step-by-step explanation:
First, we find the GCF of the two terms. We can notice that both terms are divisible by 6, so we can start by factoring that out:
6(16d^2 - 25)
Now, we can notice that the expression inside the parenthesis models after the special product a^2 - b^2 which factors to (a + b)(a - b). In this case, 16d^2 would correspond to a^2 and 25 would correspond to b^2. We can find the values of a and b:
a^2 = 16d^2
a = 4d
b^2 = 25
b = 5
We can substitute the values fo a and b into the factored form of the special product:
(a + b)(a - b)
(4d + 5)(4d - 5)
We also have the 6 we factored out earlier, so our final answer would be
6(4d + 5)(4d - 5)

Aaron is a chocolate vendor. He finds that he needs 25 identical sweet boxes to pack all the chocolates he has if he puts 24 chocolates per box. How many sweet boxes will he need to pack all the chocolates, if he puts only 30 chocolates in a box?Immersive Reader (1 Point)
Answer: 20 boxes of chocolates
Step-by-step explanation:
First find out the total number of chocolates he has:
= 25 boxes * 24 chocolates per box
= 600 pieces of chocolate
The number of boxes needed if the chocolates are packed 30 in a box is:
= Total number of chocolates / Number of chocolates per box
= 600 / 30
= 20 boxes of chocolates

u = 9
Step-by-step explanation:
5u + 11 = 56
Subtract 11 from each side.
5u + 11 - 11 = 56 - 11

Tara uses 8.8 pints of white paint and blue paint to paint her bedroom walls. 4 5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
the blue paints of 1.76 pints is used to paint her bedroom walls
Step-by-step explanation:
Given that
Tara uses 8.8 pints of white paint
And, the 4 by 5 of this amount represent the white paint
We need to find out the number of paint used by the blue paint
So,
= 8.8 - (8.8 × 4 ÷ 5)
= 8.8 - 7.04
= 1.76 pints
Hence, the blue paints of 1.76 pints is used to paint her bedroom walls

You have started keeping track of your spending habits. You have noticed that after 12 days you have
$1281 left in your account. You check again after 17 days have passed and your account is now at $861.
How many days will it take before you run out of money (assume you are spending money at a constant
rate)? Marks will be awarded only for the use of equations where t is the time elapsed in days and m is
the money left in your account in dollars.
Answer:
Time taken to elapse the remaining $861 = 10.25 days
Step-by-step explanation:
Assuming that I am spending at a rate of -x dollars per day
Let initial amount be A
The rate of expenditure = 1281-861/5 = 84 dollars per day
Time taken to elapse the remaining $861 = $861/$84 per day
= 10.25 days
Solve each equation using the substitution method.
8+=56

QUESTION: A pentagon has angles that measure 110°, 90°, 80°, 115°, and v. What is v?
Answer:
145
Step-by-step explanation:
angles in a pentagon add up to equal 540
Hence, 110 + 90 + 80 + 115 + v = 540
( note that we just created an equation that we can use to solve for v )
We now solve for v using the equation created
110 + 90 + 80 + 115 + v = 540
step 1 combine like terms
110 + 90 + 80 + 115 = 395
we now have 395 + v = 540
step 2 subtract 395 from each side
540 - 395 = 145
395 - 395 cancels out
we're left with v = 145
According to the National Association of Colleges and Employers, the mean salary for a new college graduate is $45,327. A small college wants to know if the mean salary of their most recent graduates is greater than $45,327. A random sample of 10 recent graduates from the small college was selected and the mean and standard deviation of the salary for those graduates was found. With all conditions for inference met, a significance test was conducted and a p-value of 0.045 was obtained. Which of the following statements is the most appropriate conclusion using a significance level of a = 0.05?
Answer:
There is convincing statistical evidence that the mean salary for all recent college graduates from the small college is greater than $45,327.
Step-by-step explanation:
Because the p-value of 0.045 < α = 0.05 we have convincing statistical evidence that the mean salary for all recent college graduates from the small college is greater than $45,327.

Step-by-step explanation:
A truck is bought at the price of $60,000. The value decreases at the rate of .25 every year (t). The exponential expression 60,000(0.75)t describes this situation. Find the value of the truck at 2 years.
Answer:
$33750
Step-by-step explanation:
Replace t with 2. The correct formula is
[tex]60000(.75)^t[/tex] (t is an exponent)
With t = 2, the value of the truck is
[tex]60000(.75)^2=33750[/tex]
What is the surface area of a cylinder with the given dimensions?
Express your answer to nearest hundredth. Use 3.14 for pi.
Diameter = 14cm.; Height = 6 cm.
Answer:
The surface area of a cylinder with the given dimensions is 571.48 [tex]cm^2[/tex].
Step-by-step explanation:
To find the surface area, you need to use the formula [tex]2\pi r^2 + h * 2\pi r[/tex] where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height. In this problem, the expression would be [tex]7^2 * 3.14 * 2 + 3.14*14*6[/tex] = [tex]49 * 6.28 + 3.14 * 84[/tex] = [tex]307.72+263.76[/tex] = 571.48 [tex]cm^2[/tex].
