Lyle shot three times as many baskets as cliff, while kyle shot 12 more baskets than cliff. if lyle and kyle shot the same number of baskets, how many baskets did each of them shoot?
Cliff shot 6 baskets, Lyle shot 18 baskets, and Kyle also shot 18 baskets.
Explanation:Let's represent the number of baskets Cliff shot as C.
Lyle shot three times as many baskets as Cliff, so Lyle shot 3C baskets.
Kyle shot 12 more baskets than Cliff, so Kyle shot C + 12 baskets.
Since Lyle and Kyle shot the same number of baskets, we can set their expressions equal to each other: 3C = C + 12.
Solving this equation, we find that C = 6.
Therefore, Cliff shot 6 baskets, Lyle shot 3C = 3(6) = 18 baskets, and Kyle shot C + 12 = 6 + 12 = 18 baskets.

This graph shows the amount of rain that falls in a given amount of time.
What is the slope of the line and what does it mean in this situation?
Select from the drop-down menus to correctly complete each statement
The slope of the line is ___
This means that ___ mm of rain falls every ___
To find the slope, we use the formula for slope,
[tex]m=\frac{y_{2}-y_{2}} {x_{2}-x_{1}}[/tex]
Letting the point (2,5) be [tex](x_{1},y_{1})[/tex] and the point (4,10) be [tex](x_{2},y_{2})[/tex].
Now plugging in these values in the formula for slope, we get,
[tex]m=\frac{10-5}{4-2} =\frac{5}{2}[/tex]. The slope is [tex]\frac{5}{2}[/tex].
This basically means 5 mm of rain falls in every 2 hours, or 2.5 mm of rain falls every hour ([tex]\frac{5}{2} =2.5[/tex])
ANSWER: Slope is [tex]\frac{5}{2}[/tex] and 5 mm of rain falls every 2 hours.

If the decay of 742 mg of an isotope is described by the function A(t)= 742e-0.03t, where t is time in years. Find the amount left after 84 years. Round your answer to the nearest mg.
Answer:
The amount left after 84 years is 59.70 mg.
Step-by-step explanation:
Given : If the decay of 742 mg of an isotope is described by the function [tex]A(t)= 742e^{-0.03t}[/tex], where t is time in years.
To find : The amount left after 84 years?
Solution :
The function of decay of 742 mg of an isotope is given by,
[tex]A(t)= 742e^{-0.03t}[/tex]
We have to find the amount left after 84 years.
i.e. put t=84 in the given function,
[tex]A(84)= 742e^{-0.03\times 84}[/tex]
[tex]A(84)= 742e^{-2.52}[/tex]
[tex]A(84)= 59.701[/tex]
Therefore, The amount left after 84 years is 59.70 mg.

Step-by-step explanation:
A sealed rectangular box measuring 8 x 6 x 18 contains 864 sugar cubes, each measuring 1 x 1 x 1. How many sugar cubes are touching the box?
Final answer:
A total of 456 sugar cubes touching the box.
Explanation:
To calculate the number of sugar cubes touching the box, we must consider the cubes that lie along each face of the box without double-counting the cubes that touch corners and edges.
The box dimensions are 8 x 6 x 18 inches, and each sugar cube is 1 x 1 x 1 inch.
For the top and bottom faces (6 x 18), we have
6*18 = 108 sugar cubes touching the box on each face, totaling 216 for both the top and bottom.
For the front and back faces (8 x 18), since we must exclude the top and bottom rows, we have
(8-2) x (18-2) = 6 x 16 = 96 sugar cubes for one face and 192 for both.
For the sides (8 x 6), excluding the top and bottom rows again, we have
(8-2) x (6-2) = 6 x 4 = 24 sugar cubes on one side and 48 in total for the two sides.
Adding all these together, we get 216 (top and bottom) + 192 (front and back) + 48 (sides) = 456 sugar cubes touching the box.
Remember, this method assumes a single layer of sugar cubes is in direct contact with the inside surface of the box.
Solve x + 9 = 18 - 2x
The solution to the equation x + 9 = 18 - 2x is x = 3.
What is the solution to the equation?Given the equation in the question:
x + 9 = 18 - 2x
To solve the equation x + 9 = 18 - 2x, first, collect and combine the x terms on one side of the equation and the constant terms on the other side:
x + 9 = 18 - 2x
Add 2x to both sides of the equation:
x + 2x + 9 = 18 - 2x + 2x
x + 2x + 9 = 18
3x + 9 = 18
Subtract 9 from both sides of the equation:
3x + 9 - 9 = 18 - 9
3x = 18 - 9
3x = 9
Isolate x by dividing both sides by 3:
x = 9/3
x = 3
Therefore, the value of x is 3.

what is the value for x (5x+15) (3x-3)
The value of x in the expression (5x+15) (3x-3) is 15x^2 + 30x - 45.
Explanation:The expression (5x+15) (3x-3) represents the multiplication of two binomials. To find the value of x, we can use the distributive property to simplify the expression:
Multiply the terms within the first set of parentheses: 5x * 3x = 15x^2.Multiply the terms within the second set of parentheses: 5x * -3 = -15x.Multiply the terms between the parentheses: 15 * 3x = 45x.Multiply the constant terms within the parentheses: 15 * -3 = -45.Putting it all together, we have 15x^2 - 15x + 45x - 45. Combining like terms, the expression simplifies to 15x^2 + 30x - 45.
So, the value for x in the given expression is 15x^2 + 30x - 45.

What is the slope of a line that is perpendicular to the line that goes through (5,4) and (-2,-3)?
First, let us solve for the slope of the line which it intersects with:
m’ = (y2 – y1) / (x2 – x1)
m’ = (-3 – 4) / (-2 – 5)
m’ = 1
The slope of the perpendicular line is the negative reciprocal, therefore:
m = - 1 / m’
m = - 1 / 1
m = -1
So the slope of the line is -1.

7(x - 3) = 4(x + 5)
7(x-3) = 4(x+5)
distribute:
7x-21 = 4x+20
add 21 to both sides
7x = 4x +41
subtract 4x from both sides
3x = 41
divide both sides by 3
x = 41 /3 = 13.67 ( repeating 6's) so it can be 13 2/3 as a fraction
the answer is 13 2/3
