Answer 1

Answer:

Step-by-step explanation:

This question is the same as x^8 + 3^8

X^5 + 3^5

It will look like this, x×x×x×x×x×x×x×x + 3×3×3×3×3×3×3×3 all over x×x×x×x×x + 3×3×3×3×3

Your final answer becomes x^3 + 3^3

Stephanie has a recipe that calls for 2/3 tablespoon of vanilla to make 3 1/2 dozen cookies. How many tablespoon of vanilla are needed per dozen cookies.​

Answers

4 / 21 spoonful of vanilla
Step-by-step explanation:
3 1/2 dozens = 42 cookies
Let x = spoonful of vanilla for 1 dozen of cookies
2/3 : 42 cookies
x : 12 cookies
2/3 ÷ 42 = x ÷ 12
2/3 × 1/42 = x / 12
2 / 126 = x / 12
Cross product
2*12 = 126*x
24 = 126x
Divide both sides by 126
x = 24 / 126
= 4 / 21
x = 4 / 21 spoonful of vanilla
Per dozen of cookies requires 4/21 spoonful of vanilla
Check:
4/21 per dozen × 3 1/2 dozens
4/21 × 7/2
28 / 42
2/3 spoonful for 3 1/2 dozens

Mrs. Anderson's car can go 464 miles on 16 gallons of gasoline. How many miles
can the car travel on 22 gallons of gasoline?

Answers

Answer:

638 miles

Step-by-step explanation:

Key skills needed: Proportions, Unit Rates

1) The car can go 464 miles with 16 gallons of gasoline. We need to find how many miles each gallon gasoline results in.

To find the miles per gallon, we would do 464 miles/16 gallons --> 29 mpg

This means each gallon lets the car run 29 miles.

2) To find out how many miles 22 gallons is, we then do 29 x 22, which is 638 miles.

Therefore, your answer is 638.

Hope you understood and have a nice day!!

What is 3х – 18y = 4

Answers

The answer is no solution

Simplifying
3x + -18y = 4

Solving
3x + -18y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18y' to each side of the equation.
3x + -18y + 18y = 4 + 18y

Combine like terms: -18y + 18y = 0
3x + 0 = 4 + 18y
3x = 4 + 18y

Divide each side by '3'.
x = 1.333333333 + 6y

Simplifying
x = 1.333333333 + 6y

An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers. Which equation could be used to find n, the total number of markers in stock?

Answers

Answer: n= 80 ×48+ 34×20

Step-by-step explanation:

Given: Number of large boxes = 80

Number of small boxes = 34

Number of markers in each large box = 48

Number of markers in each small box = 20

Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)

Total number of markers = n (given)

Then, n= 80 ×48+ 34×20

Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20

What could be the answer? ​

Answer:

D = 1 8.87961173

Round off to the whole number

D= 19m

Explanation of results

So to find d you will use the trigonometry formula

So you are given the

Degree which is 39°

and the hypotenuse which is 30m

Using the sin θ = Opposite Side/Hypotenuse you are going to put in the numbers where they should go in the formula so,

[tex] \sin(39) = \frac{d}{30} [/tex]

then you are going to isolate d on the right by multiplying 30 on both sides.

It will look like

30 Sin 39

So, just put this in the calculator

Solve the following system of equations by substitution. Make sure to check your solution. x + y = 5 3x - y = -5

Answers

First pick one that turns out to be a positive or negative

Answer:

(0.5)

Step-by-step explanation:

x + y = 5

3x - y = -5

Put "y" on one side to isolate

3x - y = -5

3x = y - 5

3x + 5 = y

Plug "3x + 5" in for "y" in the second equation

x + (3x + 5) = 5

4x + 5 = 5

4x = 0

x = 0

Plug  "0" in for "x" in any one of the equations

0 + y = 5

y = 5

To check, plug in "0" for "x" into the first equation and make sure they get the same answers

3(0) - y = -5

0 - y = -5

y = 5

Find the total surface area of this prism where the cross-section is an isosceles triangle
please help me
I am giving 25 points.

Answers

Answer:

620 cm²

Step-by-step explanation:

First I'll describe the net. There are 3 rectangles and 2 triangles. The triangles are identical and 2 out 3 of the rectangles are the same.

So, we know that the two similar rectangles have measurements of 13cm x 10cm. So, that's 130 cm² for one such rectangle. Add the other one and we get 260 cm².

The bottom rectangle has dimensions of 10cm x 24 cm, or 240 cm². Add that to our previous total and we'll get 500 cm².

On to the triangles. Now, we know that 1. these are isosceles triangles, and 2. they have a height of 5 cm. We can pretend to cut them in half at their highest point, which would give us 4 triangles with height 5 and length 12. Now, if you put two identical triangles together, it's a four-sided shape, and you can just multiply length by width. Let's do that.

Now we have 2 rectangles, each with width 5 and length 12. Calculate the area for each, and now we have 2 rectangles with area 60 cm². Add them together....120cm².

Add that to our previous total, and we'll get 620 cm². That should be the surface area of your prism :D

Step-by-step explanation:

The length of a rectangle is five inches less than three times its width. If the perimeter
of the rectangle is 150 inches, find the dimensions.

L=40 in. ; W=35 in.
L=60 in. ; W=45 in.
L=50 in. ; W=25 in.
L=55 in. ; W=20 in.

Answers

Answer:

L = 55 in, W = 20 in

Step-by-step explanation:

Hi there!

First we have to set up an equation for the length, which can be written as 3x - 5.

The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.

l = 3x - 5

w = x

[tex]2(3x-5) + 2(x) = 150[/tex]

Now we just have to solve!

[tex]6x - 10 + 2x = 150[/tex]

When we combine like terms and add ten to both sides, we are left with

[tex]8x = 160[/tex], which means x = 20

Using this, that means the width is 20

We can find the perimeter by plugging 20 in for x. [tex]l = 3(20) -5[/tex]

This means the length is 55.
