Two friends shop for fresh fruit. Jackson buys a watermelon for $8.85 and 3 pounds of cherries. Tim buys a pineapple for $3.35 and 2 pounds of cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Jackson spent.
Answer + Step-by-step explanation:
Jackson spent $8.85 on watermelon and p*3 dollars on cherries, which simplifies to 8.85 + 3p dollars.
Tim spent $3.35 on pineapple and p*2 dollars on cherries, which simplifies to 3.35 + 2p dollars.
To find how much more Jackson spent than Tim, we can subtract Tim's total cost from Jackson's total cost, giving:
(8.85 + 3p) - (3.35 + 2p) = 5.50 + p
So Jackson spent $5.50 + p more than Tim.
Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted:
rectangle with a length of x plus 25 and width of x plus 15 with a rectangle in the bottom right corner labeled bench that has a length of 10 and width of 3
Write an equation to determine the area, A, of the patio that will be painted.
A = (x + 18)(x + 35)
A = (x + 15)(x + 25) + 30
A = (x + 5)(x + 22)
A = (x + 25)(x + 15) − 30
Answer:
A = (x + 18)(x + 35)
Step-by-step explanation:
Answer:
A = (x + 25)(x + 15) − 30
Step-by-step explanation:
Area of the patio:
Sp = lwl = x +25w = x + 15S = (x + 25)(x + 15)Area of bench:
Sb= lw = 10*3 = 30Area A to be painted is the area of patio minus area of bench:
A = (x + 25)(x + 15) - 30So the last choice is the correct one.

James places 1 counter in the first box.he placed 2 counters in the second box,4 counters in the third box ,8 counters in the fourth box ,and continues the pattern until he gets to the tenth box how many counters did James place in the tenth box?
He placed 512 counters in the tenth box
Because... If you do a (number pattern aka a list of numbers that follow a certain sequence or pattern) your pattern will be 1,2,4,8,16,32,64,128,256,512, So in the tenth box it will be 512 because I did the pattern and reached the tenth number, which is 512 so me and Avajcantu are correct.
You can also say 2 to the power of 9 or 10 to get 512 it’s the same thing. ⇒I hope this helped <3 and don’t copy without permission thank you!
Which matrix represents the system of equations shown below? 3x-5y=12 4x-2y=15
Answer:
[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]
Step-by-step explanation:
When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:
a column for the values of x in each equationa column for the values of y in each equationa column for the independent values of each equationsince our system of equations is:
[tex]3x-5y=12\\ 4x-2y=15[/tex]
we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:
[tex]\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right][/tex]
Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:
[tex]\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right][/tex]
Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:
[tex]\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right][/tex]
usually there is a line separating the columns for the values of x and y, and the independent values:
[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]
this is the matrix of the system of equations

15 POINTSSS ANSWER ASAP PLEASE!!!!! What is the equation, in point-slope form, of the line that is
parallel to the given line and passes through the point (4, 1)?
y-1=-2(x - 4)
y-1=-{(x-4)
oy-1= (x-4)
y-1 = 2(x - 4)
Answer:
The Answer is : D
Step-by-step explanation:
First find the slope of the line that the equation should be parallel to. In this case it is 2/1 which simplified is 2.
Next insert the X (4) of the point (4,1) and solve to see if you get the Y(1).
y-1 = 2 (4-4)
y-1= 2 (0)
y-1= 0
y= 1
In this case D is correct.
TIP*
If you see the question ask you about a parallel formula, look at the slopes of them to see if they match up. Parallel formulas have the same slope, just a tip because you can see in the answer choices none of the equations have the same slope as the line on the graph except for D.

What number multiplied by 8 will give a product of 9.6?
Answer:
1.2
Step-by-step explanation:
Write out the equation and let mbe the missing number:
8 × m = 9.6
Divide 8 to both sides:
[tex]\frac{8}{8}[/tex] × m = [tex]\frac{9.6}{8}[/tex]
Simplify for M
m = 1.2
The number that needs to be multiplied by 8 to yield the product of 9.6 is 1.2. This is calculated by dividing 9.6 by 8.

Answer: [tex]x = 11[/tex]
Solving for variable x
Move all terms containing x to the left, all other terms to the right
Add -2x to each side of the equation
[tex]-61 + 3x + -2x = -50 + 2x + -2x[/tex]
Combine like terms: 3x + -2x = 1x
[tex]-61 + 1x = -50 + 2x + -2x[/tex]

The volume of a cylinder is 63.6 cubic inches,
and its height is 9 inches. Find the diameter of
the base of the cylinder.
Final answer:
To find the diameter of the base of the cylinder, use the formula for the volume to solve for the radius, then double the radius to find the diameter.
Explanation:
To find the diameter of the base of the cylinder, we need to first find the radius. We can use the formula for the volume of a cylinder, V = πr²h, where V is the volume, r is the radius, and h is the height. Rearranging the formula to solve for the radius, we have r = √(V/πh).
Plugging in the given values: V = 63.6 cubic inches and h = 9 inches, we can find the radius: r = √(63.6/3.142 x 9).
Calculating the values: r ≈ √(20.2649) ≈ 4.5055 inches. The diameter is twice the radius, so the diameter ≈ 2 x 4.5055 ≈ 9.011 inches.

Suppose a normal distribution has a mean of 79 and a standard deviation of 7. What is P(x > or = to 86)?
Answer:
P(X >= 86) = P (Z >= 1) = 0.1587 from the Z-scores table
Step-by-step explanation:
Hopefully this time I will not make an algebraic mistake.
Ok
so mean u = 79, and standard dev = s = 7
We want P(X >= 86)
Standardize:
P ( (X - u)/s >= (86 - 79)/7 ) = P (Z >= 1) = 0.1587 from the Z-scores table
if it is P(x<=86) the answer is 0.84
