Answer:
19.99
Step-by-step explanation:
use the formula
[tex]\pi {r}^{2} h = v[/tex]
change it up so that you solve for height
[tex] \frac{v}{ {r}^{2} \times \pi } = h[/tex]
substitute values in and solve
Answer:
20.00 mm to the nearest hundredth.
Step-by-step explanation:
V = π r^2 h
22,670.8 = π * 19^2 * h
h = 22,670.8 / π * 19^2
= 22,670.8 / 1134.115
= 19.9899
The radius, R, of a sphere, is 6.3cm. Calculate the sphere's volume, V.
Use the value 3.14 for, and round your answer to the nearest tenth. (Do not round any intermediate computations.)
Answer:
V = 1046.9
Step-by-step explanation:
The equation for volume is (4/3)pi r^3
substitute 3.14 in for pi and 6.3 in for r so (4/3)*3.14*6.3^3
Jalece and Kaylyn are making brownies and muffins for a bake sale. They make 40 more muffins than brownies. They made a total of 126 sweet items for the sale. How many of each type of baked good did they make?
I really don't know I hope you can figure it out
Answer: 43 brownies and 83 muffins.
Step-by-step explanation: There are 126 sweet items in total. Jalece and Kaylyn make 40 more muffins than brownies, which means that there are more muffins than brownies. Let's try 83 muffins and 43 brownies to see if it suits what we need. With 83 muffins and 43 brownies, there are 40 more muffins than brownies, so that's correct. 83 and 43 also add up to 126, which is the total that we need.
Therefore, there are 43 brownies and 83 muffins.
Let me know if this is right! :)
Drag the tiles to the correct boxes to complete the pairs.
Match each object with the characteristic it represents.
a broom handle
the letter T
a sun ray
a cookie crumb
the horizon
rows of seats on
an airplane
ray
line segment
point
line
perpendicular lines
parallel lines
Answer:
a broom handle - line segment
the letter T - perpendicular lines
a sun ray - ray
a cookie crumb - point
the horizon - line
row of seats of airplane - parallel lines
Step-by-step explanation:
a broom handle is straight and has a beginning and end, same goes for a line segment
the letter T has two lines that intersect with one another, these lines are perpendicular
a sun ray is well, a ray
a cookie crumb is small and round, similar to a point
lines do not have a beginning or end, like the horizon line
and the row of seats on an airplane all line up together like lines that are parallel.
Hope this helps :)

Answer:
The area of figure = 260 cm²
Step-by-step explanation:
Area of figure = area of rectangle+ area of triangle
=> l×b + 1/2 ×b×h
=> 10×20 + 1/2 × 20 × 6
=> 200 + 60
=> 260 cm²
Answer:
260 cm²
Step-by-step explanation:
Area of the rectangle
= l × w
= 20 × 10
= 200 cm²
Area of the triangle
= ½bh
= ½ × 20 × 6
= ½ × 120
= 60 cm²
Area of the total figure
= Area of the rectangle + Area of the triangle
= 200 cm² + 60 cm²
= 260 cm²

A giant tortoise can walk about
1/10 meter per second on land. A cooter turtle can walk about
1/2 meter per second on land.
How long would it take a giant tortoise to travel 2 meters?
2 ÷ 1/10 = 2 ? 10 =
Answer:
its already on brainy hope this helps
Step-by-step explanation:
The rate of giant tortoise is 1/10 meters per each second.
The rate of cooter turtle is 1/2 meters per each second.
How long would it take a giant tortoise to travel 5 meters?
1 second : 1/10 m = X : 5 m
1/10x = 5
x = 50 seconds
How much longer would it take a giant tortoise than a cooter turtle to travel 10 meters on land?
1 second : 1/2 m = X : 10 m
1/2x = 10
x = 20 seconds
So the giant turtle can travel 5 meters in 50 seconds.
So the cooter turtle can travel 10 meters in 20 seconds.
How many solutions does the system formed by x - y = 2 and ay - ax + 2a = 0 have for a nonzero
number a? Give your answer and complete the explanation.
The system has (select)
solution(s). Rearranging the left side of the 2nd equation and
subtracting 2a from both sides gives-ax + ay =
a. Dividing both sides by-a gives
x-y=
So, the equations describe the same line.
Answer:
1
y = 0
x = 2
Step-by-step explanation:
The first thing we want to do to solve a system of equations is to solve one of them in terms of a single variable.
Lets start with x - y = 2
If we add y to both sides we get: x = 2 + y
Now to solve the system of equations we can substitute that value for x into the other equation. In any system of equations a solution for one must be a solution for the other as well.
ay - ax + 2a = 0
When we substitute our value of x into this equation and get the folowing:
ay - a(2 + y) +2a = 0
ay -2a - ay + 2a = 0
All of the terms cancel out on the left side leaving us with:
0 = 0
This means that the only way this system can be solved is if y is equal to 0.
Going back to the first equation x - y = 2
x - 0 = 2 so x = 2
This is the only solution to that system of equations, which means it forms a point instead of a line.

Mr. Althouse has 3/4 of a quart of orange juice in a pitcher he is using to pour drinks. He needs to fill cups that hold 1/8 of a quart. How many cups will he be able to fill if he uses half of the juice in his pitcher?
Answer:
the answer should be 6.
Step-by-step explanation:
You have to make the fractions have the same denominator, this can be done by converting the 3/4. In this case you multiply both the denominator and the numerator by 2 to get 6/8. Complete the equation 6/8 ÷ 1/8 to get 6 as the full amount. half of this number would be 3 so the final result is 3.

Answer:
x=40 m∠A=100° m∠B=80° m∠C=65°
Step-by-step explanation:
Step 1: Find relationships between the angles (corresponding, alternate exterior, alternate interior, consecutive interior, or consecutive exterior)
Step 2: m∠A + m∠B = 180°
So, (3x-20)° + (2x)° = 180°
Step 3: Solve for x (x=40)
Step 4: Plug in x to the angles
m∠A= 3(40) - 20
m∠B= 2(40)
m∠C= 2(40)-15

A hot-air balloon is flying at an altitude of 2958 feet. If the angle of depression from the pilot in the balloon to a house on the ground below is 28, how far is the house from the pilot?
Answer:
6300.70 feetStep-by-step explanation:
Let the distance between pilot and house be d.
The three points form a right triangle, with height of 2958 ft and opposite angle 28 degrees.
Find d using trigonometry
sine = opposite / hypotenusesin 28° = 2958/dd = 2958/sin 28°d = 6300.70 feetLets see
