Britt needs to work 50 hours each month to accomplish her goal.
She wants to make $4,000 and she makes $8 per hour.
This means, amount of hours she need to make $4,000 is;
4000/8 = 500 hours
Since she wants this money over 10 months, it means every month she needs to work; 500/10 = 50 hours per month.
In conclusion, britt needs to work 50 hours each month to accomplish her goal.

Consider the equation: x^2-51=14x Rewrite the equation by completing the square and what the solution to the equation
Answer:
x = 17, -3
Step-by-step explanation:
I'm not sure why this is the answer I only know because I've had it before
pretty sure you have to use (b/2) ^2
The complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Rearranging the equation x² - 51 = 14
x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10
x = 7 - 10
x = -3
Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

Courtney has $4.85 in nickels, quarters, and dimes. She has12 quarters and 7 nickels. How many more dimes than nickels does she have?
A. 8
B. 12
C. 15
D. 30
Answer:
8 dimes
Step-by-step explanation:
A quarter is $0.25, so 0.25 should be multiplied by the number of quarters she has:
0.25 * 12 = 3.00
A nickel is $0.05, so 0.05 should be multiplied by the number of nickels she has:
0.05 * 7 = 0.35
If we add this together, we get 3.35, and the rest of the money Courtney has is in dimes. First, find the amount of money left:
4.85 - 3.35 = 1.50
A dime is $0.10, so divide the amount of money left by 0.10 to find the number of dimes Courtney has:
1.50 ÷ 0.10 = 15
Subtract 15 by the number of nickels Courtney has to find how many more dimes she has than nickels:
15 - 7 = 8 dimes

Solve the problem by making up an equation. A man could arrive on time for an appointment if he drove the car at 40 mph; however, since he left the house 15 minutes late, he drove the car at 50 mph and arrive 3 minutes early for the appointment. How far from his house was his appointment?
And if the appointment is x miles away from man's house the equation is
Answer:
40 miles
Step-by-step explanation:
Since we are dealing in mph, change the minutes to hr
15 min: 15/60 = .25 hrs
3 min: 3/60 = .05 hrs
:
Let t = his normal drive time to work in hrs
then
40t = the distance to work
Write a distance equation; dist = speed * time
50(t-.25 + .05) = 40t
50(t - .20) = 40t
50t - 10 = 40t
50t - 40t = 10
10t = 10
t = 1 hr normal time to work
therefore
40(1) = 40 mi to work
:
:
Confirm this by finding the dist when he went 50 mph for 48 min (.8hrs)
50(1-.25+.05) = 50(.8) = 40 mi also

Which of the following numbers are less than -0.625
A) -8/5
B) -5/8
C)-0.5
*Choose all that apply*
Answer:
A) -8/5
Step-by-step explanation:
First, convert -8/5 and -5/8 to decimals
-8/5 = -1.6
-5/8 = -0.625
-0.5 is greater than -0.625 because it is closer to 0.
So, the only number less than -0.625 is -8/5, which is equivalent to -1.6
So, the correct answer is A) -8/5

One of the roots of equation x^(2)-(3p-4)x+11p-5=0 is 8. Find the other root. Find the value of p.
Answer:
other root: x = 9
p = 7
Step-by-step explanation:
first, find p:
(8)² - (3p - 4)8 + 11p -5 = 0
64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0
91 - 13p = 0
-13p = -91
p = 7
plug in p to find the polynomial:
x² - (3(7) - 4)x + 11(7) - 5 = 0
x² - (21 - 4)x + 77 - 5 = 0
x² - 17x + 72
find the roots:
we know that 8 is one of the roots, so one factor is (x - 8)
the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8
that number is -9
so the poly nomial factors to be: (x-8)(x-9)
so the roots are x = 8 and x = 9
Answer:
p = 7
Step-by-step explanation:
x²-(3p-4)x+11p-5=0 ...(1) Root: 8, x-8 is factor
(x-8) (x- (11p-5)/8) = 0
x² -8x - ((11p-5)/8)*x + (11p-5) = 0
x² - (8 + (11p-5)/8) x + 11p-5 = 0 ----(2)
compare(1) and (2): 3p-4 = 8 + (11p-5)/8
24p - 32 = 64 + 11p - 5
13p = 91
p = 7
check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

Math page 340 what number would you multiply the dividend and divisor by to make 5.72 divide 0.52 easier to divide?
Answer:
Multiply both the divisor and the dividend by 10 to make it easier to divide
Step-by-step explanation:
As given division equation in a more suitable format that shows the dividend and the divisor that is = [tex]\frac{5.72}{0.52}[/tex]
so now we we will make the two parts to be whole number
first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places
so, that we multiplying both of them by a 10 will make them whole numbers
so so correct answer is 10
[tex]\frac{5.72\times 10}{0.52 \times 10} =[/tex] 11
