Answer:
8 Hours
Step-by-step explanation:
Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.
4 people x 14 hours = House
56 hours = House
56 hours is required to paint a house.
7 people x H hours= House
7 people x H hours = 56
(7 people x H hours)/ 7 = 56 / 7
You divide 7 on both sides to isolate H on one side.
H hours = 8
So H = 8 which is the amount of hours needed.

Step-by-step explanation:
If k is the midpoint of, jk=11x-7 and kl=6x+2, find jl
Answers
Answer:
JL = 118/5
Step-by-step explanation:
Because K is the midpoint, we know that JK and KL are going to equal each other because of the Segment Addition Postulate.
JK + KL = JL
So we know that JK = 11x-7 and KL = 6x+2
Now, we solve for X.
11x-7 = 6x+2
In order to get X alone, we must get the X's all to one side and the numbers to one side.
11x-7 = 6x+2
+7 +7
11x = 6x + 9
-6x -6x
5x = 9
x = 9/5
Now, we plug X into the equations.
JK = 11x - 7
JK = 11(9/5) - 7
JK = 99/5 - 7
JK = 64/5
KL = 6x + 2
KL = 6(9/5) + 2
KL = 54/5
Now, we add the numbers (fractions, really) together so that we can get the whole value of the line.
64/5 + 54/5 = 118/5

Answer:
8Step-by-step explanation:
Given the expression 3 * 2 2/3
This can also be expressed as;
3 * 2 2/3
= 3 * 8/3
= (24/3)
= 8
hence the product of both numbers is 8
The equivalent value of the fraction is A = 8
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first fraction be represented as p
Let the second number be represented as q
Now , A = pq
when the value of p = 2 2/3
And , when the value of q = 3
On simplifying the equation , we get
A = ( 2 2/3 ) / ( 3 )
So , the left hand side of the equation is equated to the right hand side by the value of ( 2 2/3 ) / ( 3 )
A = ( 2 2/3 ) / ( 3 )
A = ( 8/3 ) / ( 3 )
On simplifying , we get
Multiply by 3 on the fraction , we get
A = ( 8 x 3 ) / 3
A = 8
Therefore , the value of A = 8
Hence , the fraction is A = 8

Answer:
z + y = 52; z - y = 10; z = 31; y = 21; $9.85 total
Step-by-step explanation:
The variables are defined in the problem statement. The equations could be ...
z + y = 52 . . . . . . total number of coins
z - y = 10 . . . . . . . 10 more quarters than dimes
These equations can be solved by adding them together.
(z +y) +(z -y) = (52) + (10)
2z = 62 . . . . . . . simplify
z = 31 . . . . . . . . . divide by 2
31 -10 = y = 21 . . . . find the number of dimes
There are 31 quarters and 21 dimes.
The value of the coins is ...
31($0.25) +21($0.10) = $7.75 +2.10 = $9.85

Answers
Answer:
7569.36
Step-by-step explanation:
Given that a quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days,
First convert 1.25 days to hours
1.25 × 24 = 30 hours
Using exponential equation
N = No ( 1 - R% )^t
Where N = new value of the quantity
No = initial value
R = rate
t = time
N = 7800 ( 1 - 0.001 )^30
N = 7800 ( 0.999 )^30
N = 7800 × 0.97043
N = 7569.36154
N = 7569.36 to the nearest hundredth.
Therefore, the value of the quantity after 1.25 days is 7569.36

Answers
Answer:
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface
Step-by-step explanation:
At the surface of the water in the swimming pool, the height of elevation is 0.
Thus, if you swim 60 ft below the surface, it means you are going in the negative direction when we consider a number line. Thus, distance = -60 ft
Now, when you swim back up by 30 ft, it is in the positive direction. Thus, total distance is now; -60 + 30 = -30 ft
Thus value denotes a negative direction and it means you are 30 ft below the surface of the water.

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A lacrosse goalie saved 9 of 12 shots. How many additional consecutive saves must the goalie make to raise his percentage to 0.850?
Answers
he would have to take 8 more shots.
Step-by-step explanation:
9saves divided by 12 shots = .75
if you keep adding a shot and a save each time, you get to 17saves divided by 20shots=.85.
Hope this helps!
The percentage can be determined by multiplying the fraction to 100. In order to raise his save percentage to 0.850 goalie has to make one additional save.
Given that,
The number of shots saved out of 12 = 9.
Save percentage = (number of saves ÷ number of shots faced)
In the given case save percentage is as below,
= 9 ÷ 12
= 0.75
Suppose the number of saves to increase the save percentage to 0.85 be N.
Then as per the question,
0.85 = N ÷ 12
=> N = 12 × 0.85
=> N = 10
Thus, the number of additional saves is given by 10 - 9 = 1.
Hence, goalie must make one additional save to raise his percentage to 0.850.

What is complex number?The complex number is a combination of real number and imaginary number. The representation of complex number is like, a + bi.
where a is real part and b is imaginary part, the value of i is √-1.
i × i = -1
i⁴ = 1
Given that, pair of complex numbers
(6 +3i )×( 6 - 3i) = 6×6 -6×3i + 6×3i - (3i × -3i)
= 36 - 18i + 18i + (-3i × 3i)
= 36 + 9
= 45
(4-5i) × (4+5i) = 4×4 + 4×5i - 4×5i - (5i × -5i)
= 16 - 20i + 20i + (-5i × 5i)
= 16+25
= 41
(-3+8i) × (-3-8i) = -3×-3 + (-3× -8i) - 3×8i + (8i × -8i)

Step-by-step explanation:
so the first step to this is to create and equation for each
for guys gym the equation would be 5x+100 and for bob's gym the equation would be 8x+160
because we want them to equal each other we write the equation
5x+100=8x+160 and solve for x to see how many months it will take for the gyms to charge the same amount
step 1 subtract 100 from each side
5x=8x+60
step 2 subtract 8 from each side
-3x=60
step 3 divide each side by -3
x=-20 it will take -20 week for them to charge the same amount
