The inequality in the total amount of purchase is the greater than inequality
The inequality to find the additional amounts x you can spend to get free delivery is 24.00 + x > y
How to determine the inequality?The given parameters are:
Small pizza = $4.50
Salad = $3.75
The cost of two small pizzas and four salads is:
Total = 2 * 4.50 + 4* 3.75
Evaluate
Total = 24.00
Let the amount to get free delivery be y.
So, the inequality would be:
24.00 + x > y

What is 9C7 ?
A. 66
B. 55
C. 45
D. 36
Answer:
D. 36
Step-by-step explanation:
The formula for a combination :
ⁿCₓ = n! / (n - x)! x!Here we have ⁹C₇.
⁹C₇ = 9! / (9 - 7)! 7! = 9! / 2! x 7!9 x 8 x 7! / 2! x 7!9 x 8 / 236There are 36 different ways to arrange ⁹C₇. Therefore, the correct answer is option D.
Given that, ⁹C₇.
The number of combinations of n different things taken r at a time, denoted by nCr and it is given by, nCr=n!/r!(n−r)!,where 0 ≤ r ≤ n.
⁹C₇ = 9!/7!(9-7)!
= 9×8×7!/7!×2!
= 9×8/2×1
= 9×4
= 36
Therefore, the correct answer is option D.

The equation of the circle is (d) (x -3)^2 +(y - 1)^2 = 58
How to determine the circle equation?The given parameters are:
Center, (a,b) = (3,1)Point, (x,y) = (0,-6)Start by calculating the radius using:
r^2 = (x -a)^2 +(y - b)^2
So, we have:
r^2 = (0 -3)^2 +(-6 - 1)^2
Evaluate
r^2 = 58
The circle equation is then calculated using:
(x -a)^2 +(y - b)^2 = r^2
This gives
(x -3)^2 +(y - 1)^2 = 58
Hence, the equation of the circle is (d) (x -3)^2 +(y - 1)^2 = 58

FIND THE VALUES OF X AND Z FOR BRAINLIEST! :)))
Answer:
x = 20
z = 87
Step-by-step explanation:
Suplementary angles:
9x - 87 + 87 = 180
9x = 180
x = 20
Vertical angles:
z = 87
Answer:
z=87 x=20
Step-by-step explanation:
z=87 because vertical angles are congruent
87x2=174
360-84 =186
186/2=93 (the other 2 vertical angles are 93 each)
9x-87 =93
9x=180
x=20
What is the radius of a circle with a Circumference of 64 pi yards?
Please give me the answers to all three I will mark u brilliant
Answer:
First know the formula for the area of a circle;
A = π[tex]r^{2}[/tex]Where 'π' represents pi(3.14 or 22/7), and 'r' stands for the radius being squared.
For the first problem, we can see that 12 is our diameter.
And to find the radius, we need to find 1/2 of the diameter (half of the diameter), so;
D/2 = R
Replace with actual values;
12/2 = 6, 6 is our radius.
Now we plug this into our formula:
A = π[tex]r^{2}[/tex]
A = 3.14(6^2)
A = 3.14(36)
A = 113.04 centimetres is the area of the circle.
For the second problem, we can see that 18 is our diameter.
And to convert the diameter into the radius, we do what we did to the past problem, find 1/2 of the diameter.
So;
D/2 = R
18/2 = 9, 9 is our radius.
Now we plug this into our formula:
A = π[tex]r^{2}[/tex]
A = 3.14(9^2)
A = 3.14(81)
A = 254.34 inches is the area for this circle.
For the third problem, we can see that our radius is already given, 5.
So now we just simply and easily plug this into our formula;
A = π[tex]r^{2}[/tex]
A = 3.14(5^2)
A = 3.14(25)
A = 78.5 meters is the area for this circle.

Vera has challenged Alexey to a round of Marker Mixup. Marker Mixup is a game where there is a bag of 5 red markers numbered 1 through 5, and another bag with 5 green markers numbered 6 through 10
Alexey will grab 1 marker from each bag, and if the 2 markers add up to more than 12 he will win If the sum is exactly 12, he will break even, and If the sum is less than 12, he will lose $6
What is Alexey's expected value of playing Marker Mixup?
Answer:
Step-by-step explanation:
The total possble combinations = 5 * 5 = 25 ways.
The number of ways to get exactly 12
= 2,10 3,9 4,8 5,7 = 4 ways.
The ways to get > 12
= 3,10 4,9 4,10 5,8 5,9 5,10 = 6 ways.
So the number of ways to get < 12 = 25 - 4 - 6 = 15 ways.
Expected value

Step-by-step explanation:
(3)
Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{4}[/tex] x + 5 ⇒ m = [tex]\frac{1}{4}[/tex]
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]
y = [tex]\frac{1}{6}[/tex] x + 4 ⇒ m = [tex]\frac{1}{6}[/tex]
y = - [tex]\frac{1}{6}[/tex] x + 5 ⇒ m = - [tex]\frac{1}{6}[/tex]
y = [tex]\frac{1}{6}[/tex] x + 3 ⇒ m = [tex]\frac{1}{6}[/tex]
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{6}[/tex]
the 2nd and 4th lines are perpendicular

How to calculate the interior angle of a triangleA triangle is a 2-dimensional shape with 3 sides an interior angle
Since the sum of the interior angles of a triangle is 180 degrees, hence;
8x - 4 + 76 + 44 = 180
8x + 116 = 180
8x = 180 - 116
8x = 64
x = 64/8

The basketball team has four players who can play the center position. Their heights (in
inches) are 78, 80, 77, and 80.
a) List all 6 possible SRSs of size n = 2, calculate the mean height for each sample.
b) Display the sampling distribution of the sample mean on a dotplot.
c) If the sample size was increased to n = 3, what would happen to the sampling distribution?
(statistics)
The mean height for each sample from the basketball team will be 79, 77.5, 79, 78.5, 80, and 78.5
How to calculate mean?For sample 1, the mean will be:
= (78 + 80)/2 = 79.
For sample 2, the mean will be:
= (78 + 77)/2 = 77.5
For sample 3, the mean will be:
= (78 + 80)/2 = 79
For sample 4, the mean will be:
= (80 + 77)/2 = 78.5
For sample 5, the mean will be:
= (80 + 80)/2 = 80
For sample 6, the mean will be:
= (77 + 80)/2 = 78.5
When the sample size was increased to n = 3, the shape of the sampling distribution becomes bell shaped on the population mean.

Jacob wants to determine the principal amount still owed on his mortgage loan. He knows that the interest portion of his last monthly payment was $391.42. If he is paying interest at the rate of 11½%, what was the outstanding balance of the loan before that last payment was made?
If the interest rate is 11½%. The outstanding balance of the loan before that last payment was made is:$40,843.83.
Loan Oustanding balanceFirst step is to find the annual interest
Annual interest= $391.42 x 12
Annual interest= $4,697.04
Second step is to calculate the outstanding balance
Outstanding balance=Annual interest/Interest rate
Oustanding balance= $4,697.04/ 11½%,
Outstanding balance =$40,843.826
