Digit in tens place = 5
value = 50
54,450
Digit in hundreds place = 4
value = 400

A family drove to a resort at an average speed of 30 mph and later returned over the same road at an average speed of 50 mph. Find the distance to the resort if the total driving time was 8 hours.
Answer:
150 Miles
Step-by-step explanation:
Let's say it takes x time to get there.
X x 30=(8 - 6) x 50 (The distance is the same)
30X=400 - 50X=7 X=5 hours.
So the distance is 5 x 30=150 miles.
Angel sum theorem ……….
Answer:
y = 42º
Step-by-step explanation:
The unmaked angle of the bottom triangle is 90º
The sum of the angles is 180
y + 90 + 48 = 180
combine like terms
y + 138 = 180
subtract 138 from both sides
y = 42º

Find the factorization of the polynomial below. 81X2 - 18x+1
A. (18x-1)2
B. (9x-1)2
C. (9x + 1)2
D. (18x + 1)2
Answer:
B.(9 x -1)^{2}
Step-by-step explanation:
Rewrite the expression into the form of a^2\pm 2ab+b^2:(9 x)^{2} - 2 \times 9 x + 1^{2}
Factor the expression using a^{2}\pm 2ab+b^{2}=(a\pm b)^{2}:(9 x -1)^{2}
we have 81x^2 - 18x+1 = (9x)^2 -2.9x + 1 = (9x -1)^2

Lucy is going to watch a movie in her collection. She has 5 action movies, 4 comedies, and 3 dramas.
She will randomly select one movie. What is the probability that the movie she selects is not a drama?
Write your answer as a fraction in simplest form.
Answer:
3/4
Step-by-step explanation:
5 action+4 comedy+3 drama= 12 total movies
12 will be the denominator of our fraction.
The question asks: What is the probability that the movie she selects is NOT a drama?
So, we add the number of action and comedy movies.
5+4=9
9 is our numerator.
But wait! We have to simplify the fraction 9/12!
9 divided by 3= 3
12 divided by 3= 4
Reduced answer: 3/4

LeAnnne has $4 in dimes and nickels. She has 10 more dimes than nickels. How many nickels does she have?
Answer:
21 she has 21 nickels
Step-by-step explanation:
Googel
The number of nickels LeAnne has 20 and the number of dimes LeAnne has 30.
Given that, LeAnnne has $4 in dimes and nickels.
Let the number of dimes be d and the number of nickels be n.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
She has 10 more dimes than nickels.
That is, d=n+10
So, 0.05n+0.10d=4
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
5n+10(n+10)=400
5n+10n+100=400
15n=300
n=20
d=n+10
d=30
Therefore, the number of nickels LeAnne has 20.

A pool with a square bottom is to have a volume of 2000 cubic feet. The owners plan to use a fancy tile to complete the pool. The sides of the pool will cost $80 per square foot and the bottom of the pool will cost $40 per square foot. Find the pool dimensions that will minimize the cost of construction.
The pool dimensions that will minimize the cost of construction are length of square bottom = 20 ft and height of pool = 5 ft
Let l be the length of side of the square bottom of the pool and h be the height of the pool.
Its volume V = l²h
Now, the total surface area of the pool equal the area of its sides plus the area of its base.
The area of its 4 sides is 4lh.
Since the cost of the side of the pool is $80 per square foot, the total cost for the sides of the pool is C = $80 × 4lh = $ 320lh
Also, The area of its square bottom is l².
Since the cost of the side of the pool is $40 per square foot, the total cost for the square bottom of the pool is C' = $40 × l² = $ 40l²
So, the total cost of the pool is C" = C + C' = 320lh + 40l²
C" = 320lh + 40l²
Since the volume equals 2000 ft³, V = l²h
2000 = l²h
h = 2000/l²
Substituting h into C", we have
C" = 320lh + 40l²
C" = 320l × 2000/l² + 40l²
C" = 640000/l + 40l²
To find the value of l which makes C" minimum, we differentiate C" with respect to l and equate it to zero.
So, dC"/dl = d(640000/l + 40l²)/dl
dC"/dl = d(640000/l)/dl + d(40l²)/dl
dC"/dl = -640000/l² + 80l
Equating dC"/dl to zero, we have
-640000/l² + 80l = 0
-640000/l² = -80l
Cross-multiplying, we have
640000 = 80l³
Dividing through by 80, we have
l³ = 640000/80
l³ = 8000
Taking cube root of both sides, we have
l = ∛8000
l = 20 ft
We differentiate C" twice to determine if this value of l gives a minimum for C".
So, d²C"/dl² = d(-640000/l² + 80l)/dl
d²C"/dl² = d(-640000/l²)/dl + d(80l)/dl
d²C"/dl² = 640000/l³ + 80
Substituting l = 20, we have
d²C"/dl² = 640000/l³ + 80
d²C"/dl² = 640000/20³ + 80
d²C"/dl² = 640000/8000 + 80
d²C"/dl² = 80 + 80
d²C"/dl² = 160 > 0
Since d²C"/dl² = 160 > 0. So, l = 20 ft gives a minimum for C".
Since h = 2000/l²
Substituting l = 20 into the equation, we have
h = 2000/l²
h = 2000/20²
h = 2000/400
h = 5 ft
So, the pool dimensions that will minimize the cost of construction are length of square bottom = 20 ft and height of pool = 5 ft

Which number is a zero of the given function?
g(x) = (x^2– 36) (x + 7)
The zeros of the function g(x) = (x² - 36)(x + 7) are x = 6 and x = -6.
To find the zeros of the function g(x) = (x² - 36)(x + 7), we need to identify the values of x that make the entire function equal to zero.
For a function to be equal to zero, at least one of its factors must be zero. Therefore, we set each factor to zero and solve for x:
Setting the first factor, x² - 36, to zero:
x² - 36 = 0
Now, add 36 to both sides of the equation:
x² = 36
Next, take the square root of both sides:
x = ±√36
x = ±6
Setting the second factor, x + 7, to zero:
x + 7 = 0
Now, subtract 7 from both sides of the equation:
x = -7
The zeros of the function g(x) = (x² - 36)(x + 7) are x = 6 and x = -6.
