Answer:

$3(7)/(10)$

Step-by-step explanation:

In Mathmatics there are certain words to describe symbols for example of in this situation of is used as a multiplication sign there are also other words used to describe multiplication like per, times, and doubles.

So now that we know the of is a multiplication sign we can insert it in the problem. $(2)/(3) * 1(4)/(5) + 2(1)/(2)$

So using PEMDAS which stands for

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

So we first multiply $(2)/(3) * 1(4)/(5)$ and we get $1(1)/(5)$ .

Then we add $1(1)/(5) + 2(1)/(2)$ and we get $3(7)/(10)$ .

Help!!A restaurant uses a container that is shaped like a right triangular prism to package carry out sandwich orders. A net of the container is shown below. What is the surface area? I need this question ASAP!! Thanks

Answers

145.9 square inches is the surface area of the container.

Split the container as per the given picture,

Area of rectangle 1 with dimension 8 by 3 = 24

Area of rectangle 2 with dimension 11.3 by 3 = 33.9

Area of a triangle with dimension 8 by 8 = 1/2*8*8 = 32

Thus,

Surface area of the container = 2*Area rectangle 1 + 2*area of the triangle + Area of the rectangle 2

Surface area of the container = 2 * 24 + 2 * 32 + 33.9

The surface area of the container = 145.9 in²

Therefore, the surface area of the given container is 145.9 square inches.

Max was on vacation twice as long is Jared and half as long as Wesley. The boys were on vacation a total of three weeks. How many days with each boy on vacation?

Answers

To begin with, the question is asking for the answer in days, so let's change 3 weeks to days. There are 7 days in 1 week; 3 weeks times 7 days = 21 days.
21 total days of vacation.

Max + Jared + Wesley = 21 days
(Let's use the first letter of their name to represent their vacation time)

M + J + W = 21 [This is the equation we'll be coming back to]

Now, we can use the clues given in the question to have an equation for each variable/boy.

Max was on vacation twice as long as Jared. We can interpret this as M= 2J Max was on vacation only half as long as Wesley. We can interpret this as M = (1/2)W.

So far we have these three equations: M + J + W = 21M = 2J M = (1/2)W

To have an equation for each individual boy, we must rearrange the last two equations in the list.

First, M = 2J.
Divide both sides by 2
M/2 = 2J/2
(1/2)M = J

Second, M = (1/2)W
Multiply both sides by 2
2M = W

New equations:
M + J + W = 21 [From the old list]
J = (1/2)W
W = 2M

Now we can substitute the last two equations into the first one.
M + J + W = 21
M + (1/2)W + 2M = 21
[Combine Like Terms]
(7/2)M = 21

Then, solve for M (Max's vacation days):
Multiply both sides by 2/7
$((2)/(7))* ((7)/(2)m)= ((2)/(7))*(21)$
M = 6

Now we know Max was on vacation for 6 days.

If Max was on vacation twice as long as Jared, that means Jared was on vacation HALF as long as Max.

So...
J = (1/2)M
J = (1/2) * 6
J = 3
Jared was on vacation for 3 days

Wesley was on vacation twice as long as Max so... W = 2M
W= 2*6
W = 12
Wesley was on vacation for 12 days.

Let's double check our answer:
M + J + W = 21 days6 + 3 + 12 = 21
The numbers work out so the math is correct. Hope this helps and makes sense!
