Yeah you have a square garage 366 ft.² floor space she recently built in addition to the garage is the square but I have 50% more force base what is the length of one side of the garage originally what is the length of one side of the garage now what was the percent increase in the length of one side
Answer:
a) The original length of the garage is 19.13 feet.
b) The new length of the garage is 23.43 feet.
c) Percentage increase in the length of one side is 22.5%.
Step-by-step explanation:
The original area of the garage = 366 [tex]ft^{2}[/tex]
a) Area of a square = length x length (since it has equal length of sides)
= [tex]l^{2}[/tex]
So that;
366 = [tex]l^{2}[/tex]
l = [tex]\sqrt{366}[/tex]
= 19.131
The original length of the garage is 19.13 feet.
b) 50% more force base = 50% x 366
= 0.5 x 366
= 183
The new area of the garage = 366 + 183
= 549 [tex]ft^{2}[/tex]
So that;
549 = [tex]l^{2}[/tex]
l = [tex]\sqrt{549}[/tex]
= 23.431
The new length of the garage is 23.43 feet.
c) Increase in the length of one side = 23.431 - 19.131
= 4.3 ft
Percentage increase in the length of one side = [tex]\frac{4.3}{19.131}[/tex] x 100%
= 22.48 x 100%
≅ 22.5%
Percentage increase in the length of one side is 22.5%.

Khali and Juan are using ribbon to decorate their art project. The ratio of the length of Khali's ribbon to the length of Juan's ribbon is 8:5 If Khali used a total of 72 cm of ribbon, how much did Juan use?
Answer:
45 cm
Step-by-step explanation:
It is given that,
The ratio of the length of Khali's ribbon to the length of Juan's ribbon is 8:5.
We need to find the length of ribbon used by Juan if Khali used a total of 72 cm of ribbon. ATQ,
[tex]\dfrac{K}{J}=\dfrac{8}{5}\\\\\dfrac{8}{5}=\dfrac{72}{J}\\\\J=\dfrac{5\times 72}{8}\\\\J=45\ cm[/tex]
So, Juan uses 45 cm of the ribbon.
What numbers show the factors of 28
The factors of 28 are the numbers, which on multiplication in pairs results in the original number. These factors are 1,2,4,7,14 and 28. Since, 2 x 14 = 28, therefore (2,14) is a pair factor of number 28.
Answer:
1,2,7,4,14,28 prime factor are2,2,7

If y varies directly as x, and y=6 when x=2, what is the value of y when x=7
Answer:
21
Step-by-step explanation:
y∞x
y=kx(where k is the constant)
6=2k
6/2=k
3=k
there the relationship between y,k and x is y=3x
y=3(7)
y=3×7
y=21

Find a so that the point (-1,3) is on the graph of f(x) = ax^2 + 2
Answer:
a = 1
Step-by-step explanation:
Plug in the point into the equation, then solve for a:
f(x) = ax² + 2
3 = a(-1²) + 2
3 = a + 2
1 = a
So, a = 1
The points on a graph are the true values of the graph
The value of a is 1
The equation is given as:
[tex]f(x) = ax^2 + 2[/tex]
At point (-1,3), the equation becomes
[tex]3 = a(-1)^2 + 2[/tex]
Evaluate the exponent
[tex]3 = a(1) + 2[/tex]
This gives
[tex]3 = a + 2[/tex]
Subtract 2 from both sides
[tex]a =1[/tex]
Hence, the value of a is 1

Suppose a five minute overseas call cost $6.45 in a 10 minute call cost $11.40 the cost of the car in the length of the call are related write an equation to show the cost of the call of any duration approximately how long can you talk on the phone if you have $51 to spend
Answer:
The Equation for this is given as
C = $0.99m + $1.50
Where m = number of minutes
C = Cost of the call
If you have $51 to spend , the duration of the call is approximately 50 minutes
Step-by-step explanation:
Step 1
We find the difference in the cost of the calls.
$11.40 - $6.45
= $4.95
The cost for a 5 minute call =
$4.95 ÷ 5 = $0.99
Hence, The extra charges for the 5 minutes call =
$6.45 - $4.95 = $1.50
The Equation for this is given as
C = $0.99m + $1.50
Where m = number of minutes
C = Cost of the call
If you have $51 to spend, the number of minutes you would get is :
$51 = $0.99m + $1.50
$51 - $1.50 = 0.99m
$49.50 = 0.99m
m = $49.50/0.99
m = 50 minutes
Therefore, If you have $51 to spend , the duration of the call is approximately 50 minutes

From the diagram, we can see that angle A and angle C are base angles of an isoceles triangle. Hence they are equal. i.e
m∠A = m∠C
(3x+10) = (2x+30)
3x+10 = 2x+30 (subtract 2x from both sides)
3x + 10 - 2x = 30
x + 10 = 30 (subtract 10 from both sides)
x = 30 - 10
x = 20
