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.

Step-by-step explanation:
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

Step-by-step explanation:
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%.

25 POINTS AND BRAINLIEST Which choice passes through (12, 10) and is parallel to y = 3x + 6?
A. Y= -1/3x + 14
B. Y= -1/3x + 10
C. Y= 3x - 12
D. Y= 3x - 26
Answer:
D
Step-by-step explanation:
The equation of the line passes through the point (12, 10) and parallel to the line y = 3x + 6 is Y= 3x - 26. The correct option is D.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the line passes through (12, 10) and is parallel to y = 3x + 6.
The slope of the line will be the same as that of the slope of the line which is parallel.
The equation of the line will be written as,
y = 3x + c
The y-intercept will be calculated as,
10 = (3 x 12 ) + c
c = -26
The equation of the line will be,
y = mx + c
y = 3x - 26
Therefore, the equation of the line passes through the point (12, 10) and parallel to the line y = 3x + 6 is Y= 3x - 26. The correct option is D.

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
