What is the factored form of this expression? 5p^3-10p^2+3p-6
Answer:
[tex](5p^2+3)(p-2)[/tex]
Step-by-step explanation:
In this problem, we need to write the factor form of expression [tex]5p^3-10p^2+3p-6[/tex].
It can be done as follows :
[tex]5p^3-10p^2+3p-6=(5p^3+3p)+(-10p^2-6)[/tex]
Taking common form the terms as follows :
[tex]=p(5p^2+3)-2(5p^2+3)[/tex]
It can be also written as :
[tex]=(5p^2+3)(p-2)[/tex]
Hence, the factored form of [tex]5p^3-10p^2+3p-6[/tex] is [tex](5p^2+3)(p-2)[/tex]
Answer: (p-2)(5p^2+3)

For a slope intercept for, you have the formula y=mx+b where you would place the slope in the spot of m and the y-intercept in the spot of b.
New York City has a population of 8.55 million and 300 square mile. Manhattan has 1.64 million and 23 square miles. How much greater is the population of Manhattan than New York City?
Given :
New York City has a population of 8.55 million and 300 square mile area .
Manhattan has 1.64 million and 23 square miles area .
To Find :
How much greater is the population density of Manhattan than New York City.
Solution :
Population density of New York City :
[tex]D_{NY}=\dfrac{8.55}{300}=0.029 \ million/mile^2\\\\D_{M}=\dfrac{1.64}{23}=0.071 \ million/mile^2[/tex]
Now ,
[tex]D_{M}-D_{NY}\\\\(0.071-0.029)=0.042\ million/miles^2[/tex]
Therefore , population density of Manhattan is [tex]0.042\ million/miles^2[/tex] greater than New York City .
Hence , this is the required solution .
A water tank holds 486 gallons but leaking at a rate 4 gallons per week. A second water tank holds 648 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the 2 tanks? The amount of water that holds the two tanks will be the same in _ weeks.
The first tank contains
486 gal - (4 gal/week) t
gal of water after t weeks.
Similarly, the second tank contains
648 gal - (7 gal/week) t
gal of water.
The tanks hold the same amount of water when these two amounts are equal:
486 gal - (4 gal/week) t = 648 gal - (7 gal/week) t
(7 gal/week) t - (4 gal/week) t = 648 gal - 486 gal
(3 gal/week) t = 162 gal
t = (162 gal) / (3 gal/week)
t = 54 weeks
Which of the following numbers would appear first if we were listing the numbers in descending order?
List the first 4 terms of the sequence. f(1) = 7, f(n) = f(n-1)+4
Answer:
7, 11, 15, 19
Step-by-step explanation:
Using the recursive rule with f(1) = 7 , then
f(2) = f(1) + 4 = 7 + 4 = 11
f(3) = f(2) + 4 = 11 + 4 = 15
f(4) = f(3) + 4 = 15 + 4 = 19
The first 4 terms are 7, 11, 15, 19

Step-by-step explanation:
4x+4(x-6)=3(2x+4)
distribute
4x+4x-24=6x+12
combine like terms
8x-24=6x+12
carry across equal sign
2x-24=12
carry across equal sign
2x=36
divide
x=18
Answer:
X = 18
Step-by-step explanation:
4x + 4(x -6) = 3(2x + 4)
4x + 4x -24 = 6x + 12
8x -24 = 6x + 12
+24 +24
8x = 6x + 36
-6x -6x
2x = 36
Divide 2x and 36 by 2
X = 18

It rained 0.84 inches on Saturday and 0.8 inches on Sunday. How much did it rain on Saturday and Sunday combined?
Answer:
1.64
Step-by-step explanation:
The first step to do is to line up the decimal points. We have to add a zero to 0.8 so that the decimal points will align (this does not change the value).
0.84
+0.80
Then bring down the decimal point into the answer column, and add like normal.
0.84
+0.80
1.64

In the figure at right, line l is a line of symmetry, m∠B=8x-4°, and m∠D=2x+14°. Use this information to write an equation and solve for x. Hint: Set ∠B = ∠D
Answer:x=3
Given: angle B = angle D
So, 8x-4=2x+14
8x-2x=14+4
6x=18
Therefore, x=3

At a grocery store, Rick bought 4 loaves of bread and 3 gallons of milk for $20. Danny bought 6 loaves of bread and 2 gallons of milk for $25. Identify the cost of a loaf of bread and a gallon of milk
Hey there! I'm happy to help!
Let's call the cost of a bread loaf b and the cost of a milk gallon m. Here is the info we have.
4b+3m=20
6b+2m=25
We solve one equation for b or m (we will solve the first one for b.
4b+3m=20
Subtract 3m from both sides.
4b=20-3m
We divide both sides by 4.
b=5-3/4m
We plug this value of b into the second equation to solve for m.
6(5-3/4m)+2m=25
We use distributive property to undo the parentheses.
30-4.5m+2m=25
We combine like terms.
30-2.5m=25
We subtract 30 from both sides.
-2.5m=-5
We divide both sides by -2.5
m=2
We plug this m into one of the original equations to find b.
4b+3(2)=20
4b+6=20
Subtract 6 from both sides.
4b=14
Divide both sides by 4.
b=3.5
So, a loaf of bread costs $3.50 and a gallon of milk costs $2.00.

There are two options for buying crickets option A.7 pounds of crickets for 3.15 option B.3 pounds of crickets for 1.47 which option is better to buy justify your answer
Answer: 7
pounds for 3.15 is a better option
Step-by-step explanation:
Here in this question, we want to know which of the two options is a better option for buying crickets.
To know the better option, we shall be needing the unit price in whatever system to be used;
7 pounds of crickets for 3.15;
so the unit price here will be 3.15/7 = 0.45 per pound
For the second system, we have 3 pounds for 1.47 so the unit price will be 1.47/3 = 0.49 per pound
As we can see, the first option commands a cheaper price per unit, so it is the better option to buy

[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex]
Step-by-step explanation:
Step 1. Turn the second fraction upside down (it becomes a reciprocal):
[tex]\frac{4}{5}[/tex] becomes [tex]\frac{5}{4}[/tex]
Step 2. Multiply the first fraction by that reciprocal:
[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex] = ?
3 x 5 = 15
7 x 4 = 28
[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex] = [tex]\frac{15}{28}[/tex]
