Answer:
-12
Step-by-step explanation:
I am assuming that you want (f*g)(4), which is the product of f and g at x = 4.
If this is actually the case, then one way to evaluate (f*g)(4) is to find f(4) and g(4) separately and then multiply the results together. This gives us
f(4)*g(4) = (8 + 4)*(-4 + 3) = -12

Find the length of the variable w
Answer:
w = 3
Step-by-step explanation:
Δ BDE and Δ BAC are similar, then the ratios of corresponding sides are equal, that is
[tex]\frac{BD}{BA}[/tex] = [tex]\frac{DE}{AC}[/tex] , substitute values
[tex]\frac{w}{w+2}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5w = 3(w + 2) ← distribute
5w = 3w + 6 ( subtract 3w from both sides )
2w = 6 ( divide both sides by 2 )
w = 3

If you rent a canoe for 3 hours, you will pay $45.
Write a linear equation to represent the total cost (y) of renting the canoe for x hours.
Answer:
y = 15x
Step-by-step explanation:
I'm assuming there is no up-front cost. This means that per hour, you need to pay $45/3 = $15, since $45 is for 3 hrs.
y = 15x

Solve for b at the top
And x at the bottom
I’ll give 17 points
Answer:
b = -1
x = 1
Step-by-step explanation:
8 - (b - 2) = 11
subtract 8 from both sides
- (b - 2) = 3
distribute
-b + 2 = 3
subtract 2 from both sides
-b = 1
now, to make the b positive, we make the other side negative by multiplying.
b = -1
-2x+ 4 = 5 -3x
subtract 4 from both sides
-2x = 1 -3x
add 3x to both sides
1x = 1
divide by 1
x = 1

The number of people that attended the first basketball game of the season was 840. The number of people attending the last basketball game of the season increased by 30%. How many people attended the last basketball game
Answer:
1092 people attended the last basketball game.
Step-by-step explanation:
Given that:
Number of people who attended the first basketball game = 840
Percent increase for last game = 30%
Total people who attended last game = (100+30)% = 130% of first game
Number of people who attended last game = [tex]\frac{130}{100}*840[/tex]
Number of people who attended last game = 1.30*840 = 1092
Hence,
1092 people attended the last basketball game.
Question 5
Reduce in LOWEST terms: 4 dimes and 2 nickels
Answer:
2 quarters
Step-by-step explanation:
4 dimes = 40 cents
2 nickels = 10 cents
40 + 10 = 50 cents
So 50 pennies = 50 cents
So 10 nickels = 50 cents
So 5 dimes = 50 cents
So 2 quarters = 50 cents

PLS HELP pls pls pls
Answer:
y=0
Step-by-step explanation:
Simplifying
y + y = 0
Combine like terms: y + y = 2y
2y = 0
Solving
2y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = 0
Simplifying
y = 0
Answer:
The correct answer is,
[tex]2y[/tex]

Evan has equal numbers of pop songs, jazz songs, and rock songs loaded on his personal music player. He has it set to play songs on a random shuffle. Suppose Evan is designing a simulation that could be used to estimate the probability that the next two songs to play are both jazz songs.
Which simulation design could Evan use to estimate the probability?
A. Coin
Let heads (H) = jazz
Let tails (T) = pop or rock
Toss coin three times. Repeat.
B. Number cube
Let 1 = pop
Let 2 jazz
Let 3 = rock
Roll cube four times. Repeat.
C. Number cube
Let 1,2 = pop
Let 3,4 = jazz
Let 5, 6 = rock
Roll cube two times. Repeat.
D. Random Digits
Let 1,2,3 = jazz
Let 4,5,6 = pop
Let 7,8,9,0 = rock
Select two random digits. Repeat.
Answer:
I think it is C. Number cube
Let 1,2 = pop
Let 3,4 = jazz
Let 5, 6 = rock
Roll cube two times. Repeat.
Step-by-step explanation:
A zebra runs 15 miles per hour faster than an elephant. The zebra runs 8 miles in
the same time that an elephant runs 5 miles. Write and solve an equation to
calculate the speed of each animal.
Answer:
elephant: 25 mph; zebra: 40 mph
Step-by-step explanation:
The time required is the same in each case, so we need to set up an equation of the form distance1/speed1 = distance2/speed2:
8 miles 5 miles
------------- = time = -------------
speedz speede
From this we get:
8 5
------------------ = -------------------
speede + 15 speede
Cross multiplying, we get: 8(speed e) = 5(speede) + 75, or
3(speede) = 75, or
speede = 25 mph
Then speedz = 25 mph + 15 mph = 40 mph = speedz
Mrs.Butter is a wonderful baker and she makes delicious cookies, Last Saturday she sold 72 peanut harger cookies. She also sold seme oatmeal cookies. If the ratio of peanut butter cookies sold to oatmeal okies sold was 9:1. how many peanut butter and oatmeal cookies did she sell altogether?
Answer:
she sold 8 oatmeal cookies
total = 72+8=80 cookies sold
Step-by-step explanation:
72 at a 9:1 ratio, would be 72:8
so she sold 8 oatmeal cookies
total = 72+8=80 cookies sold
Further explanation:
for every 9 PB cookies she sold, she sold one OM cookie.
She sold 72 PB cookies, so she sold 8 OM cookies because 72/9=8.
