Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school. If Angela works alone, it will take her five and a half hours. If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
Answer:
3.08 hours
Step-by-step explanation:
Preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours.
If Brandon works alone, it will take him 7 hours. If they work together, it will take them approximately hours ?
This is calculated as:
The Number of hours they worked together = T
1/5.5 + 1/7 = 1/T
= 7 + 5.5/(5.5)(7)
= 12.5/38.5
1/T = 12.5/38.5
Cross Multiply
12.5T = 38.5
T = 38.5/12.5
T = 3.08 hours
The time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
[tex]W_1=\dfrac{1}{n}[/tex]
In preparation for the homecoming football game, members of the student body are painting the spirit rock in front of the school.
If Angela works alone, it will take her five and a half hours. The work done by Angela in one hour is,
[tex]A=\dfrac{1}{5.5}\\A=\dfrac{2}{11}[/tex]
If Brandon works alone, it will take him 7 hours. The work done by Brandon in one hour is,
[tex]B=\dfrac{1}{7}[/tex]
The work done in one hour, when the work together,
[tex]A+B=\dfrac{2}{11}+\dfrac{1}{7}\\A+B=\dfrac{14+11}{77}\\A+B=\dfrac{25}{77}\\A+B=\dfrac{1}{3.08}[/tex]
Thus, the time required when Angela and Brandon work together, for the preparation for the homecoming football game, is 3.08 hours.

Rob is flying a kite with a string that makes a 70-degree angle with the ground. If the kite string is 27 meters long, how high is the kite above the ground?
(Please use the exact ratio to calculate the missing side and round your answer to the nearest hundredth.)
The kite is meters above the ground.
Answer:
25.37
Step-by-step explanation:
Use SOH or Sin∅=[tex]\frac{opposite}{hypotenuse}[/tex]
So Sin(70)= [tex]\frac{x}{27}[/tex]
Multiply both sides of the equation to end up with 27Sin(70)=x

What percentage of the total does Leah have?
A
3.33%
B.
30%
с
70%
D
33.95%
Answer:
B
Step-by-step explanation:
30 % of the total does Leah have.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Leah wants to buy a necklace for her mother's birthday that costs $48.50.
Leah has currently $14.55.
We need to find 14.55 is what percentage of 48.55.
Let x be the percentage.
48.55x=14.55
Divide both sides by 48.55
x=14.55/48.55
x=0.299
Now multiply with 100
x=0.299×100=29.9
x=30%
Hence, 30 % of the total does Leah have.

Given Point A (3,-4) and Point B (8,6) on directed line segment AB, what is the y-coordinate of Point F
that partitions AB in the ratio of 3:2?
Answer:
(6,2) y-coordinate is 2
Step-by-step explanation:
The coordinates of the point F on directed line segment AB that partitions AB in the ratio 3 :2 are: (6, 2)
What is Coordinate geometry?The formula for finding the coordinates of a point that divides the line in ratio m:n are given by:
We are given that Point A (3,-4) and Point B (8,6) on directed line segment AB.
Here (x1,y1) and (x2,y2) are coordinates of the two points line passed through
(x1,y1) = A(-3,-4)
(x2,y2) = B(8,6)
Ratio: 3 : 2
m = 3
n = 2
Putting the values in the formula
( x, y) = (3 x 8 + 2 x 3 /5 , 3 x 6 + 2 x (-4) /5 )
( x, y) = (24 + 6 / 5 , 18 - 8 /5)
( x, y) = (30/5, 10/5)
( x, y) = (6, 2)
Hence,
The coordinates of the point F are: (6, 2)

En 4 años, Jake será dos veces mayor que Jane. Actualmente, Él es tres veces mayor que Jane. ¿Cuántos años tendrá Jake en 5 años?
Answer:
17 años
Step-by-step explanation:
Deje que la edad de Jane sea x
Deja la edad de Jake por y
y = 3x ------- 1
y + 4 = 2 (x + 4)
y = 2x + 8 - 4
y = 2x + 4 ------- 2
x = y / 3 ------- 3
Sustituye 3 en 2
y = 2 (y / 3) + 4
Multiplicar por 3
3y = 2y + 12
3 años - 2 años = 12
y = 12
Pero y = 3x
Por eso;
x = 12/3
x = 4
Dentro de cinco años

The ratio of fish to turtles in a pond is
20:3. There are 80 fish in the pond.
How many turtles are in the pond?
A 10
14
C 12
D 16
Answer:
C : 12
Step-by-step explanation:
Answer:
12 turtles
Step-by-step explanation:
First, if the ratio of fish to turtles is 20:3 and there are 80 fish, then we know that you have to divide 80 by 4 to get the answer 20. However, to find out how many turtles there are you need to do the opposite and multiply instead of dividing. So you do 3 x 4, which get you your answer.
