Answer:
B. 9πx^6
Step-by-step explanation:
Putting the given radius into the area formula gives ...
A = πr^2
A = π(3x^3)^2 = π(3^2)(x^(3·2))
A = 9πx^6

find the circumference of the pizza use 3.14 the pizza is 7 inches
Answer:
45 inches
Step-by-step explanation:
C = (pi)(diameter).
Assuming that the radius of the pizza in this case is 7 inches, the diameter is twice that, or 14 inches.
Thus, the circumference of the pizza is C = (3.14)(14 inches) = 45 inches
approximately.

Helen has a box of marbles.
12
of the marbles are yellow.
18
of the marbles are red.
The rest of the marbles are blue.
Helen pulls one marble out of the box at random, records its color, replaces it, and mixes up the marbles again. If she does this 200 times, how many blue marbles should she expect to pull out?
Answer:
I don't know because I don't know how many total marbles there are. If you know how many marbles there are in total that would help me figure out the problem.
Step-by-step explanation:
Samir has a bag that contains pineapple chews, lemon chews, and lime chews. He performs an experiment. Samir randomly removes a chew from the bag, records the result, and returns the chew to the bag. Samir performs the experiment 45 times. The results are shown below:
A pineapple chew was selected 34 times.
A lemon chew was selected 8 times.
A lime chew was selected 3 times.
Based on these results, express the probability that the next chew Samir removes from the bag will be lemon chew as a decimal to the nearest hundredth
Answer:
0.18
Step-by-step explanation:
Answer:
.18
Step-by-step explanation:
The experiment occurred 45 times, lemon was selected 8 times.
Probability the next chew will be lemon:

Find the discriminant of the following quadratic equation then state the number of rational, irrational, and imaginary solutions.
Equation: −6x2−6=−7x−9
Discriminant: Answer
Solutions:
Answer:
-6x² - 6 = -7x - 9-6x² + 7x - 6 + 9 = 0-6x² + 7x + 3 = 06x² - 7x - 3 = 0Discriminant:
D = (-7)² - 4*6*(-3) = 49 + 72 = 121Since D > 0, there are 2 real solutions:
x = (- (-7) ±√121 )/12x = (7 ± 11)/12x = 1.5, x = -1/3Consider the following system of equations.
3x + 5y = 18
6x − 5y = 20
Decide which procedures eliminate the x variable and which eliminate the y variable. Drag and drop each procedure that will eliminate one of the variables into the appropriate category.
Subtract the second equation from the first equation.
Add the first and second equations. Multiply the first equation by −2; then add the two equations.
Divide the second equation by −2; then add the two equations. Subtract the first equation from the second equation.
Multiply the first equation by 2 then add the two equations.
Eliminate x Eliminate y
Answer:
Option B
On adding the first and second equations y can be eliminated
Step-by-step explanation:
The two equations are as follows
3x + 5y = 18 -- Eq (1)
6x − 5y = 20 -- Eq (2)
Adding equation 1 and 2, we get -
3x + 6x + 5y -5y = 18
9x = 18
x = 2
y = (18-3*2)/5
y = 12/5 = 2.4

Step-by-step explanation:
The given point (-3, -9) is reflected over X-axis
Answer:
The correct answer is (3, 9)
Step-by-step explanation:
The rule for reflecting over the X-axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X-axis and mapped onto point P', the coordinates of P' are (5,-4).

The following are the last 10 run scores Colin got in cricket:
18, 9, 7, 35, 30, 21, 33, 12, 30, 31
a) Work out Colin's mean score.
b) Colin plays cricket again on Sunday. He gets 27 runs.
What is his new mean score?
Give your answers as decimals.
Answer:
a) 22.6
b) 23
Step-by-step explanation:
a)
Step 1: 18 + 9 + 7 + 35 + 30 + 21 + 33 + 12 + 30 + 31 = 226
Step 2: 226/10 = 22.6
b)
Step 1: 226+27 = 253
Step 2: 253/11 = 23
please solve this geometry equation with the work ! for 40 points and brainliest
Answer:
D. 16 times.
Step-by-step explanation:
Volume of a cylinder = π r^2 h
π r^2 h = 432
Now if the diameter is reduced by 1/4 then the radius is reduced by a fourth also.
Let the new height be H, then:
432 = π (r/4)^2 H
so π r^2 h = π(r/4)^2 H
r^2 h = r^2 H / 16
h = H/16
H = 16h.

ANSWER FOR BRAINLIEST AND 50 POINTS:
The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MEAN of the temperatures. Round to the nearest tenths place.
A. 82.3
B. 89
C. 83
D. 78
Answer:
A.
mean=82.286
Rounded to the tenths place would be= 82.3
Step-by-step explanation:
The Mean is found by adding all of the values together
Then dividing it by how many values there are.
In this instance, all the values added up equal 576
576 now will be divided by how many temperatures are recorded.
576/7=82.286
82.286 Rounded to nearest tenth=82.3

Which statement about cones is true? If a cone is intersected by a plane parallel to the base, then the cross section is a triangle. If a cone is intersected by a plane parallel to the base, then the cross section is a triangle. If a cone is intersected by a plane parallel to the base, then the cross section is a square. If a cone is intersected by a plane parallel to the base, then the cross section is a square. If a cone is intersected by a plane parallel to the base, then the cross section is a rectangle. If a cone is intersected by a plane parallel to the base, then the cross section is a rectangle. If a cone is intersected by a plane parallel to the base, then the cross section is a circle.
Answer: If a cone is intersected by a plane parallel to the base, then the cross section is a circle.

needs to be fenced is 50 feet long. Did Mr.
Hernandez buy enough fencing? Determine the
number of feet Mr. Hernandez still needs to buy
or how many extra feet he has purchased.
(1 meter = 3.28 feet.)
Answer:
well yes he has 2.4 extra
Step-by-step explanation:
1 meter is 3.28 feer so 3.28 x 16 is 52.4 and he only need 50.
hoped this hlepd and you have to give me brailyest. i just want to help...
