Answer:
D.1767.1 in³
Step-by-step explanation:
volume of a sphere=4/3πr³
where r=radius of the sphere
Given diemeter= 15in
so radius=15/2=7.5in
volume=4/3×π×(7.5)³
=4/3×22/7×(7.5)³
=1767.1in³

How many real solutions exist for this system of equations? Y = -x + 1 y = -x2 + 4x − 2 A. Zero B. One C. Two D. Infinite
Answers
Answer:
Two solutions
Step-by-step explanation:
Given the functions Y = -x + 1 y = -x² + 4x − 2
Since they are both y values, we will equate them to have:
-x+1 = -x² + 4x − 2
Equate to zero
x²-x-4x+1+2=0
x²-5x+3 = 0
Since the resulting equation is quadratic (highest degree being 2), hence there will be two solutions to the equation
Jlvesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is
the height of the rocket in centimeters, and the rocket was fired from the ground at timet = 0, where t is
measured in seconds.
Jivesh also has a more powerful Model B rocket. For this rocket, he uses the equation h=-90t4 + 300t.
When is the height of the Model B rocket 250 centimeters? Round your answers to the nearest
hundredth.
After t =
seconds, the rocket will have reached a height of 250 centimeters.
Answers
Answer:
After t = 1.67 seconds, the rocket will have reached a height of 250 centimeters.
Step-by-step explanation:
Given
[tex]h = -90t^2 + 300t[/tex] --- correct expression
Required: When does height = 250 cm
To do this, we have:
[tex]h = 250[/tex]
This gives:
[tex]250 = -90t^2 + 300t[/tex]
Rewrite as:
[tex]90t^2 - 300t + 250 = 0[/tex]
Divide through by 10
[tex]9t^2 - 30t + 25 = 0[/tex]
Expand
[tex]9t^2 - 15t - 15t + 25 = 0[/tex]
Factorize:
[tex]3t(3t - 5) -5(3t - 5) = 0[/tex]
[tex](3t - 5)(3t - 5) = 0[/tex]
This gives:
[tex]3t - 5 = 0[/tex]
Solve for 3t
[tex]3t = 5[/tex]
Solve for t
[tex]t = \frac{5}{3}[/tex]
[tex]t = 1.67s[/tex]
The radius of a circle is 1 inch. What is the area?
r=1 in
Give the exact answer in simplest form.
Answers
Answer:
3.14 square inches or π square inches
Step-by-step explanation:
The radius of a circle is 1 inch. What is the area?
r=1 in
The formula for the area of a circle is given as:
πr²
The radius (r) = 1 inch
Hence,
Area of the circle = π × 1²
= 3.1415926536 square inches
Approximately = 3.14 square inches or we can say that the Area of the circle = π square inches

A.
y = 0.28x + 0.75
B.
y = 0.75x +0.56
C.
y = 0.75x + 0.28
D.
y = 0.56x + 0.75
Answers
Answer:
A.
y = 0.28x + 0.75
Step-by-step explanation:
Check all that applies using teaspoons of baking powder, x = 5
A.
y = 0.28x + 0.75
When x = 5
y = 0.28x + 0.75
= 0.28(5) + 0.75
= 1.4 + 0.75
y = 2.15
B.
y = 0.75x +0.56
When x = 5
y = 0.75x +0.56
= 0.75(5) + 0.56
= 3.75 + 0.56
= 4.31
C.
y = 0.75x + 0.28
When x = 5
y = 0.75x + 0.28
= 0.75(5) + 0.28
= 3.75 + 0.28
= 4.03
D.
y = 0.56x + 0.75
When x = 5
y = 0.56x + 0.75
= 0.56(5) + 0.75
= 2.8 + 0.75
= 3.55
The equation represents the height of fudge brownies with x teaspoons of baking powder is
y = 0.28x + 0.75

Answers
Answer:
124
Step-by-step explanation:
To find the surface area, we add the area from all faces or the prism.
the first face, we can put 8 times 2.5, which is 20. There are two of these faces, so we have 40 in our area so far.
next the other face. 4 times 2.5 is 10, and there are two of these faces. 60 in out area.
now the top and bottom faces. 8 times 4 is 32. there are two of these faces, and 60 +64 = 124

11. A bag contains 2 blue marbles and 2 green marbles. What is the probability of drawing a blue marble followed by a green marble, without replacing the first marble before drawing the second marble?
Please show work ty
Answers
Answer: your answer should be 50%
Step-by-step explanation: This is because there are only four marbles in the bag total and only 2 are blue and only 2 are green so your chances of pulling out either is 50%
Answer:
33%
Step-by-step explanation:
2 blue marbles + 2 green marbles = 4 marbles
1st draw for blue: 2/4 (2 blue marbles out of 4 marbles)
2nd draw for green: 2/3 (1 less marble from 4, marble not put back in)
2/4 x 2/3 = 4/12 = 1/3 = 0.33 or 33%

Write and solve an equation to determine the unknown variable. Then find the measure of the unknown angles.
Your options are:
A. x + 7 + 2x - 40 = 180 One angle is 78 degrees and the other is 102 degrees
B. x + 47 = 180 The unknown angles are both 133 degrees
C. x + 7 + 2x - 40 = 90 One angle is 48 degrees and the other is 42 degrees
D. x + 7 = 2x - 40 The unknown angles are both 54 degrees
Answers
Answer:
Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

A. 33 in.
B. 400 in.
C. 3,600 in.
D. 1,200 in.
Answers
Step-by-step explanation:
400 in. is the correct answer
For a pyramid, volume= (1/3) x b x h where
B= base area, and
h= height .
So, volume= (1/3) x (200in^2) x (6in) = 400in^3.

Group A parallelogram, Group B Quadrilateral.
Answer: Parallelogram and Quadrilateral.
The two ways of classifying shapes are: Parallelogram and Quadrilateral.
There are different ways to classify an item.
How do one identify the type of quadrilateral?Quadrilaterals can be known by;
It is a polygon with four sides.
Since rectangle is known to be a parallelogram that has four right angles.
A trapezoid is regarded as a quadrilateral with only one pair of parallel sides.
And Parallelograms are known to be shapes that has four sides with only two pairs of sides that are known to be parallel.
So we conclude that Group A parallelogram, and Group B Quadrilateral.
