Answer:
56
Step-by-step explanation:
Answer:
B = 56
Step-by-step explanation:
A + B = 90 degrees
(6x - 8) + (5x + 21) = 90
6x - 8 + 5x + 21 = 90
(6x + 5x) + (-8 + 21) = 90
11x + 13 = 90
11x + 13 - 13 = 90 - 13
11x = 77
11x/11 = 77/11
x = 7
Plug into (5x + 21).
5(7) + 21 =
35 + 21 = 56
B = 56

Working together ,Ann and Jane painted a total of 480 square feet in 3 hours they each painted the same num of sq feet what is the average rate that ann and Jane each painted in square feet per hour
The average rate that Ann and Jane each painted is 80 square feet per hour.
What is rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now it is given that,
Total area painted by Ann and Jane = 480 square feet
Time taken in painting 480 square feet = 3 hours
Now let x and y be the amount painted by Ann and Jane.
Since,they each painted the same number of sq feet
⇒ x = y
Therefore, Total area painted = x + y = 2x
or, 2x = 480 square feet
⇒ x = 240 square feet
So, the same num of sq feet painted by both is 240 sq feet each
Now average rate = num of sq feet painted by each/time taken
⇒ average rate = 240/3 square feet per hour
or, average rate = 80 square feet per hour
Thus, The average rate that Ann and Jane each painted is 80 square feet per hour.

Identify all of the roots of the function f(x) = x^3 - 5x^2-2x+24
The roots are -2, 3 and 4.
What are roots?A solution to an equation, usually expressed as a number or an algebraic formula.
Given:
x³-5x²-2x+24
As, x+2 divides the x³-5x²-2x+24 gives quotient x²−7x+12.
Now,
x²−7x+12.
=x²− 4x -3 x+12.
=x(x-4) - 3(x-4)
=(x-4)(x-3)

A pool estimate that 43% of likely voters are in favor of additional restrictions on teen drivers the Poll has a margin of error of plus or minus 4%. Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Estimated number of voters in favor of additional restriction = 43%
Margin of Error = ±4%
Write and solve the absolute value equations to find the minimum and maximum percent of voters that support the restriction:
Minimum percentage of voters = 4% lesser than the estimated number of voters
Maximum percentage of voters = 4% greater than the estimated number of voters
Let number of voters = v
|v - 43%| = ±4%
v = - 4% + 43% = 39% = minimum percentage
v = +4% + 43% = 47% = maximum percentage
39% ≤ v ≤ 47%

Answer:
B. the slope is -2, and the y-intercept is 12.
Step-by-step explanation:
i cant really explain stuff that well but basically you have to find the slope. you have to subtract 18-12 and you would get 6. then subtract -3-0 and that would be -3.
you then have to divide 6 (-3) and you would get -2. i never knew how to get 12 tho- sorry lol

Answer:
c = 0
Step-by-step explanation:
Step 1: Write equation
15 - 5(4c - 7) = 50
Step 2: Solve for c
Distribute -5: 15 - 20c + 35 = 50Combine like terms: -20c + 50 = 50Subtract 50 on both sides: -20c = 0Divide both sides by -20: c = 0Step 3: Check
Plug in c to verify it's a solution.
15 - 5(4(0) - 7) = 50
15 - 5(-7) = 50
15 + 35 = 50
50 = 50

For questions 18-20, if l \\ m, find the values of x and y
Answer:
Step-by-step explanation:
18). l║m and a transverse is intersecting these lines.
(11y - 32)° = (6x + 7)° [Vertical angles]
-6x + 11y = 39 -------(1)
(3x - 16)° + (6x + 7)°= 180° [Same side exterior angles]
9x - 9 = 180
9x = 189
x = 21
Now substitute the value of x in the equation (1)
-6(21) + 11y = 39
11y = 39 + 126
y = 15
19). l║m and a transversal is intersecting these lines.
(8x - 14)° + (5y + 16)° = 180° [Linear pair of angles]
8x + 5y = 178 --------(1)
(8x - 14)° = (5x + 34)° [Alternate exterior angles]
8x - 5x = 48
3x = 48
x = 16
From equation (1)
8(16) + 5y = 178
128 + 5y = 178
5y = 178 - 128
y = 10
20). From the figure attached,
m∠CAB = (5y - 23)°
Since sum of interior angles of a triangle is 180°
m∠CAB + m∠ACB + m∠ABC = 180°
(5y - 23)° + (2x + 13)° + (47)° = 180°
2x + 5y = 143 ------(1)
(5y - 23)° = 3x°
3x - 5y = -23 -----(2)
Equation (1) + Equation (2)
(2x + 5y) + (3x - 5y) = 143 - 23
5x = 120
x = 24
From equation (1)
2(24) + 5y = 143
48 + 5y = 143
5y = 95
y = 19
Samir begins riding his bike at a rate of 6 miles per hour. Twelve minutes later, Chris leaves from the same point and bikes along the same route at 9 miles per hour. How long after Chris begins riding does he catch up to Samir? 4 min 12 min 24 min 40 min
Answer:
The correct option is C) 24 min.
Step-by-step explanation:
It is given that:
Speed of Samir riding his bike = 6mph
Speed of Chris riding his bike = 9 mph
Let the time taken by Chris be x min. Then the time was taken by Samir be x+12
We know that the formula for the distance is
Where d is the distance, t is the time and r is the rate.
According to the question:
[tex]9x=6(x+12)\\9x=6x+72\\9x-6x=72\\3x=72\\x=24[/tex]
Hence, after 24 minutes Chris will catch up to Samir.
Therefore the correct option is C) 24 min.
