Hi, I don't need this really fast, but I really don't understand how to do surface area and lateral surface area with rectangular prisms, triangular prisms and cylinders. Any tips will be greatly appreciated. I will give you brainlist. ( idk how to spell lol ) :)
Answer:
The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid.
Answer:
The volume of a pyramid
V=1/3⋅B⋅h
The area of the rectangle:
A=C⋅h
A=12.6⋅6
A≈75.6
To find the volume of a cylinder we multiply the base area (which is a circle) and the height h.
V=πr2⋅h

Jack works after school. Each day he is paid a set amount, plus an hourly wage. Look at the table. Choose the linear function f Jack can use to find his pay. Hours 1 1.5 2 2.5 3 Pay 18 23 28 33 38 A. f(x) = 10x + 8 B. f(x) = 15x + 3 C. f(x) = 0.5x + 1 D. f(x) = x + 18
Answer:
The correct linear equation is;
f(x) = 10x + 8
Step-by-step explanation:
To choose the correct linear function, we just need to take a specific point, then substitute in each of the equations given to get the one right
The correct one will be the one in which when the x-value is substituted, we will get the y-value
Let us pick (1,18)
Let us begin testing;
A. f(x) = 10x + 8
f(1) = 10(1) + 8 = 10 + 8 = 18
Let us use another point to test this
The second point is (1.5,23)
f(1.5) = 10(1.5) + 8
= 15 + 8 = 23
What is the value of the ratio 1/2:3?
The value of the ratio 1/2: 3 is 1/6
A ratio is a comparison of two things or two quantities. It is the relative size of two quantities expressed as the quotient of one divided by the other.
We need to find the value of 1/2 : 3
This can be written as 1/2 : 3/1
On further simplification, this can be wriiten as
1/2 x 1/3
which is equal to 1/6
This can be written in the form of ratio as 1 : 6
Therefore, the value of the ratio 1/2: 3 is 1/6

Answer:
∠ AED = 92°
Step-by-step explanation:
The chord- chord angle ADE is half the sum of the arcs intercepted by the angle and its vertical angle, that is
∠ AED = [tex]\frac{1}{2}[/tex] ( arc AD + arc BC )
= [tex]\frac{1}{2}[/tex] (146 + 38)°
= [tex]\frac{1}{2}[/tex] × 184°

In the equation a= 3/b is a positive, real number. As the
value of b is increased so it becomes closer and closer to
infinity, what happens to the value of a ?
Answer:
The value of a tends to zeroStep-by-step explanation:
Given the expression a = 3/b
as the denominator of the of the expression b increases the value of the output is known to be decreasing. if the value of b now goes so large to become an infinite, value then the value of a will goes to zero as shown;
If b = ∞
a = 3/∞
a = 0
Note that for any constant value a, the ratio a/∞ will always tends to zero

Write a linear function f with f(0)=7 and f(3)=1.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
a = ( 0 , 7 ) & b = ( 3 , 1 )
First need to find the slope using the following equation :
[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]
[tex]slope = \frac{1 - 7}{3 - 0} \\ [/tex]
[tex]slope = \frac{ - 6}{3} \\ [/tex]
[tex]slope = - 2[/tex]
_________________________________
We have following equation to find the point-slope form of the linear functions using the slope and one of the through points .
[tex]y - y(0) = m \times ( \: x - x(0) \: )[/tex]
[tex]x(0) = x - coordinate \: \: of \: \: through \: \: point \\ [/tex]
[tex]y(0) = y - coordinate \: \: of \: \: through \: \: point \\ [/tex]
[tex]m = slope[/tex]
I choose point (( a )) to put in the equation.
[tex]y - 7 = - 2 \times (x - 0)[/tex]
[tex]y - 7 = - 2x + 0[/tex]
[tex]y - 7 = - 2x[/tex]
Add sides 7
[tex]y - 7 + 7 = - 2x + 7[/tex]
[tex]y = - 2x + 7[/tex]
This the slope-intercept form .

Plums cost $0.77 per pound Mangoes cost $1.32 per pound Write an expression that can be used to find the cost of buying p pounds of plums and m pounds of mangoes
Answer:
The graphs below show the cost y of buying x pounds of fruit. One graph shows the cost of buying x pounds of peaches, and the other shows the cost of buying x pounds of plums.
Which kind of fruit costs more per pound? Explain.
Bananas cost less per pound than peaches or plums. Draw a line alongside the other graphs that might represent the cost y of buying x pounds of bananas.
IM Commentary
This task allows students to reason about the relative costs per pound of the two fruits without actually knowing what the costs are. Students who find this difficult may add a scale to the graph and reason about the meanings of the ordered pairs. Comparing the two approaches in a class discussion can be a profitable way to help students make sense of slope.
Solutions
Solution: Slope as Unit Rate
The graph that represents the cost of x pounds of peaches is steeper, so it must have a larger slope. The slope can be interpreted as the unit rate; in this case it tells you the cost of a single pound of fruit.
Since the slope for the peach graph is greater than the slope of the plum graph, the cost of a pound of peaches is greater than the cost of a pound of plums.
For b, students should realize that the cost per pound of bananas will be represented by a slope that is less than either of the other two, and draw a line through the origin labeled "Bananas" and lying below both of the other graphs.
Solution: Adding a scale to the graph
Students who prefer to work with specific numbers can approach this problem by sketching in a scale on the x-axis and y-axis. For example, if they decided that a pound of peaches might cost a dollar, then they might plot the point (1,1) on the line labeled "Peaches", then fill out the rest of the scale accordingly. They could then read off the cost of a pound of plums and see that it is less than for peaches.
For the second question, they could choose any price per pound b for bananas that is less than the one they read off for plums, and then draw a line from the origin through the point (b, 1), and label it "Bananas".
Find the measurement?
Answer:
HG = 28
Step-by-step explanation:
The midsegment MN is half the sum of the 2 parallel bases, that is
[tex]\frac{HG+JF}{2}[/tex] = MN , that is
[tex]\frac{HG+16}{2}[/tex] = 22 ( multiply both sides by 2 )
HG + 16 = 44 ( subtract 16 from both sides )
HG = 28
Jerome wrote the following scenario to match the algebraic expression s 4 − 16: “16 fewer than four times the number of songs on my mp3 player” Does his scenario match the expression? Explain.
Answer:
No, because the expression s/4 - 16. In the word formed she times 4 and the letter, she should have to dived it.
Step-by-step explanation:
No, because the expression s/4 - 16. In the word formed she times 4 and the letter, she should have to dived it.
Answer:
No, Jerome’s scenario does not match the expression. The term s
4
means the number of songs is divided by four, but the scenario uses the word ‘times,’ which means multiplication. The scenario should say ‘16 fewer than one-fourth the number of songs.
