Answer:

see below

Step-by-step explanation:

This means to be able to be given a word problem like: Jessica went to the store and spent $2.25 on candy, $2.50 on chips and $2.00 for a soda. How much did Jessica spend?

Given this you are able to write: $2.25 + $2.50 + $2.00 = $6.75

Answer: In most cases, mathematical problems of real world scenarios can be solved using slope form: y=mx+b where y is the total amount, m is number per something (ex $1.50 per candy bar), and b is the fixed amount of something (ex tax).

Step-by-step explanation: (Made up problem) Person went to a candy store with $65. Person bought an ice cream cone for $5.99 and later bought a few bags of chips. The price per chip was $3.40. How many chips did Person buy?

The equation will be set up as 65=3.40x+5.99 (It is good to write out the word problem so that it is easier to identify your options like this: 65=total amount, $3.40 per bag of chip, 5.99 for ice cream).

Subtract 5.99 on both sides: 59.01=3.40x (We are solving for x, the number of chips)

Divide 3.40 on both sides to isolate x: x≅17.35 bags of chips... so Person was ripped off by getting a bag containing less than half of the amount of chips the bag should have.

To check if the answer is correct, plug in 17 to the original equation, 65=3.40(17.35)+5.99 and solve:

65=58.99+5.99

65=64.98 (this is a made-up scenario so the measurements won't be exact).

A cone with a diameter of 12 inches has a volume of 640.88 cubic inches. find the height of the cone

BlackZzzverrR [31]

Answer:

The height of the cone is $17\ in$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

In this problem we have

$r=12/2=6\ in$ ----> the radius is half the diameter

$V=640.88\ in^{3}$

assume $\pi=3.14$

substitute the values and solve for h

$640.88=\frac{1}{3}(3.14)(6)^{2}h$

$h=640.88*3/((3.14)(36))=17\ in$

Find the surface area of the triangular prism (above) using its net (below).

r-ruslan [8.4K]

Answer:

96 square units

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.

My answer:

The length of the large rectangle is: 5
The width of the large rectangle is: 7

=> Area of the large rectangle = length × width = 7*5 = 35 square units

The length of the middle rectangle is: 7
The width of the middle rectangle is: 4

=> Area of the middle rectangle = length × width = 7*4 = 28 square units

The length of the small rectangle is: 7
The width of the small rectangle is: 3

=> Area of the small rectangle = length × width = 7*3 = 21 square units

Area of top and the bottom triangles =2* $\frac{1}{2}bh$ $= 4*3 =12$

Total surface area = 35 + 28 + 21 + 12 = 96 square units

A storekeeper has two kinds of flour, one selling for 65 cents per pound, and the other selling for 95 cents per pound. How many

Murrr4er [49]

Answer:

The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds

Step-by-step explanation:

Let

x ----> amount of 65 cents per pound flour to use

y----> amount of 95 cents per pound flour to use

we know that

$x+y=100$ ----> $y=100-x$ ----> equation A

$0.65x+0.95y=0.83(100)$ ----> equation B

substitute equation A in equation B

$0.65x+0.95(100-x)=0.83(100)$

Solve for x

$0.65x+95-0.95x=83$

$0.95-0.65x=95-83$

$0.30x=12$

$x=40\ lb$

Find the value of y

$y=100-40=60\ lb$

therefore

The amount of 65 cents per pound flour to use is 40 pounds and the amount of 95 cents per pound flour to use is 60 pounds

Can please help!

sukhopar [10]

Answer:
equation is: width = area / length
width = 62.5 yd

Explanation:
For the first rectangle:
We have:
length = 75 yd and width = 60 yd
Therefore:
area = length * width
area = 75 * 60
area = 4500 yd²

For the second rectangle:
We have:
area = area of first rectangle = 4500 yd²
length = 72 yd
area = length * width
width = area / length ............> The required equation
width = 4500 / 72
width = 62.5 yd

Hope this helps :)
