Step-by-step explanation:
Each crate is in the shape of a rectangular solid. Its dimensions are length, width, and height. The rectangular solid shown in the image below has a length
4 units, width 2 units, and height 3
units. Can you tell how many cubic units there are altogether? Let’s look layer by layer.
Breaking a rectangular solid into layers makes it easier to visualize the number of cubic units it contains. This
4 by 2 by 3 rectangular solid has 24 cubic units.
A rectangular solid is shown. Each layer is composed of 8 cubes, measuring 2 by 4. The top layer is pink. The middle layer is orange. The bottom layer is green. Beside this is an image of the top layer that says
Altogether there are 24 cubic units. Notice that 24 is the length × width × height.
The top line says V equals L times W times H. Beneath the V is 24, beneath the equal sign is another equal sign, beneath the L is a 4, beneath the W is a 2, beneath the H is a 3.
The volume, V, of any rectangular solid is the product of the length, width, and height.
V = L W H
We could also write the formula for the volume of a rectangular solid in terms of the area of the base. The area of the base, B, is equal to length × width. B = L ⋅ W
We can substitute
B for L ⋅ W in the volume, formula to get another form of the volume formula.
The top line says V equals red L times red W times H. Below this is V equals red parentheses L times W times H. Below this is V equals red capital B times h.
We now have another version of the volume formula for rectangular solids. Let’s see how this works with the
4 × 2 × 3
Besides the solid is V equals Bh. Below this is V equals Base times height. Below Base is parentheses 4 times 2. The next line says V equals parentheses 4 times 2 times 3. Below that is V equals 8 times 3, then V equals 24 cubic units.
The measures of three of the interior angles of a quadrilateral are 60°, 110°, and 90°. What is the measure of the fourth angle of this quadrilateral?
Answer:
100°
Step-by-step explanation:
all four angles added together total 360°
x = 360° - 60° - 110° - 90°
x = 100°

What is the median of the first half of the data? (first quartile)
Answer:
$273
Step-by-step explanation:
1. Find the first half of the list (There are 8 numbers in the list, so the first four)
2. List them from least to greatest ($196, $248, $298, $379)
3. find the middle of the numbers ($248, $298)
4. Since there are 2, we find the mean of the 2 numbers ($273)
5. So the answer is $273

Chris can do 30 pushups in 60 seconds. At this rate
how many pushups can he do in 360 seconds?
Answer: 180 pushups
Step-by-step explanation: First set up a proportion. The proportion would be 30 pushups over 60 seconds equal x over 360 seconds. Then you would cross multiply which is 60 times x which is 60x .After that do 30 times 360 which is 10,800.Now you have 60x = 10,800.NOw divide both sides by 60 which gives you 180 as x.

A collar of Styrofoam is made to insulate a pipe. Find its volume. The large radius R is to the outer rim. The small radius r is to the edge of the insulation. Use pi ≈ 3.14 r=2 R=4 h=20
Answer:
753.6 cubic units
Step-by-step explanation:
A collar of Styrofoam is made to insulate a pipe. Find its volume. The large radius R is to the outer rim. The small radius r is to the edge of the insulation. Use pi ≈ 3.14 r=2 R=4 h=20
The volume of the pipe formula is given as:
Use pi ≈ 3.14 r=2 R=4 h=20
Volume =h × π (R² -r²)
Volume =20 × 3.14 × (4² - 2²) cubic units
Volume = 62.8 × ( 16 - 4) cubic units
= (62.8 × 12 )cubic units
= 753.6 cubic units

There are 360 seals. Of them are 9/20 are pups. The rest are adult seals . How many pups are the beach .
Answer:
162 pups are on the beach
Step-by-step explanation:
9/20 of 360
The key word "of" tells us to multiply
Variable x = number of pups
9/20 × x/360
Cross multiply
9 × 360 = 20 × x
3,240 = 20x
Divide both sides by 20
162 = x
Check our work:
9/20 = 162/360
Cross multiply
9 × 360 = 20 × 162
3,240 = 3,240

Manuel incorrectly claimed that the surface area of the cylinder
shown is about 621.7 in.. Use a formula to find the surface area of the cylinder.
Use 3.14 for it. What was his likely error?
11 in
The surface area of the cylinder is about
(Round to the nearest tenth as needed.)
Answer:
25.9%
Step-by-step explanation:
Since, the actual dimensions of the cylinder is not given we can assume the some dimension to explain the problem
Let us assume the dimension of the cylinder be
radius= 3in
height= 5 in
The expression for the total surface area of a cylinder is
T. S. A. =2πrh+2πr^2
Let us plug in the values to to find TSA
T. S. A. =2×3.14×3×5+2×3.14×3^2
Solving we get
T. S. A. =94.26+56.556
T. S. A. =150.816 in^2
Now let us find the error
we know that error % is calculated as
%error= [actual value-expected value/expected value]×100
%error= [190 -150.816/150.816]×100
%error= [39.184/150.816]×100
%error= 0.259×100
%error= 25.9%

Identify the lateral area and surface area of a right cone with radius 6 cm and slant height 13 cm.
Answer:
The lateral surface area is about = 269.747749 m squared
The surface area is about = 382.787749 m squared
Step-by-step explanation:
Answer:
L = 245 cm2 ; S = 358.1 cm2
Step-by-step explanation:
The lateral area of a right cone with radius r and slant height l is L=πrl.
The figure shows a right cone.
Apply the formula for the lateral area of a right cone L=πrl.
Substitute the known values for the radius r=6 cm and the slant height l=13 cm.
L=π(6)(13)=78π
Use a calculator to approximate. Round your answer to the nearest whole number.
L≈245
The lateral area of the cone is 245 cm2.
The surface area of a right cone with lateral area L and base area B is S=L+B, or S=πrl+πr2.
Substitute the given value for the radius r=6 cm into the formula for the area of a circle, B=πr2.
B=π(6)2=36π
Therefore, the base area is 36π cm2.
To calculate the surface area of the cone, substitute the known values into formula for surface area.
S=78π+36π=114π
Use a calculator to approximate. Round your answer to the nearest tenth.
S≈358.1
Therefore, the surface area of the cone is about 358.1 cm2.
Is a parabola a one-to-one function?
Answer:
no
Step-by-step explanation:
The function f(x)=x2 is not one-to-one because f(2) = f(-2). Its graph is a parabola, and many horizontal lines cut the parabola twice. The function f(x)=x 3, on the other hand, IS one-to-one. If two real numbers have the same cube, they are equal.

given g(x)=-x-3, solve for x when g (x) =6
Answer:
x = - 9
Step-by-step explanation:
Given g(x) = - x - 3 and g(x) = 6, then equate, that is
- x - 3 = 6 ( add 3 to both sides )
- x = 9 ( multiply both sides by - 1 )
x = - 9
Answer:
-9
Step-by-step explanation:
g(-6) = -6 - 3
g(-6) = -9
