Answer 1

Answer: We have an triangle:
base=4 in
height=3 in,
This triangle can be dividided into two equal triangles, we need calculate the hypotenuse.
leg₁=4 in/2=2 in
leg₂=3 in

Pythagoras law:
hypotenuse²=leg₁²+leg₂²
hypotenuse²=(2 in)²+(3 in)²
hypotenuse²=4 in²+9 in²
hypotenuse²=13 in²
hypotenuse=√13 in.

Now, we can find the surface area.
Surface area=2 *(rectangle area)+base area + 2(triangle area)
rectangle area=10 in x √13 in=10√13 in²
base area=10 in x 4 in=40 in²
Triangle area=(4 in x 3 in)/2=6 in²

Surface area=2(10√13 in²)+40 in²+2(6 in²)=(20√13+52) in²≈124.11 in²

Answer: 124.11 in²

Answer 2

Answer: if im correct its 22 in (4x3+10)

Tickets for the fall dance are 5$ per person or $8 for couples. In order to cover expenses, at least $1200 worth of tickets must be sold. Write an inequality that represents this situation.

Answers

✡ Answer: $5+$8p=1200 ✡

- - Why?

If you take the cost per person and for couples, you are adding them together.

Now you are going to multiply it by "x" because in this case, x is representing the number of people who actually bought the tickets.

Now you want to write a equal sign because you need it to solve up to $1200 (the cost you need to atleast get)

How do you find the absolute value of a positive number ?

Answers

Absolute value is the distance a number is away from 0. What I do is just put the # down. Ex. The absolute value of 5 is 5. The absolute Value of 98624 is 98624.

this is how you do absolute value from positive to negative...

It takes 154 cubes with side lengths of 1/2 inch to fill a rectangular prism. What is the volume of the rectangular prism? Show your work or justify your solution.

Answers

Answer:

The volume of the rectangular prism is 19.25 inches³.

Step-by-step explanation:

Given:

It takes 154 cubes with side lengths of 1/2 inch to fill a rectangular prism.

Now, to find the rectangular prism's volume.

We first find the volume of a cube to fill in the rectangular prism.

The side length of the cube = $(1)/(2)\ inch.$

Now, to get the volume of cube we put formula:

$Volume=(side)^3\n\nVolume=((1)/(2))^3 \n\nVolume=(1)/(8)\ inch^3.$

Thus, the volume of a cube is $(1)/(8) \ inch^3.$

Number of cubes = 154.

According to question, it takes 154 cubes to fill the rectangular prism.

So, to get the volume of prism we need to find the volume of 154 cubes.

Now, to get the volume of 154 such cubes we multiply the volume of a cube by number of cubes:

$(1)/(8)* 154\n\n =(154)/(8)\n\n =19.25\ inches^3.$

Therefore, the volume of the rectangular prism is 19.25 inches³.

How to solve and graph this equation ?

Answers

Start by adding 2y so that the equation becomes 2y= -3x-4 then divide by 2 on both sides so it cancelled out. (This if for if your trying to get it in y=mx+b form)
