Answer:

This ratio is not proportional. (๑・ω-)～♥”

Answer:

$ 10.50

Step-by-step explanation:

we can use a proportion to answer this question

25 : 100 = x : 7

x = (25 * 7)/100 = $1.75 (value of the discount)

Final price = 7 - 1.75 = $5.25

she bought two = 5.25 x 2 = $10.50

Answer:

If both pumpkins are 7 dollars in total than it would be 5.25 if its 7 dollars each and a discount on each it would be 10.5

Answer:

I agree with Noah's Method because following PEMDAS you have to do exponents first. 10^3 is 1000 and then you can add the 20. Jada's method is incorrect because you cannot add the two together.

I don't know how to explain this other than use a calculator.

Hope that this helps!

Step-by-step explanation:

tan 60 = 21 ÷ y

1.73 = 21 ÷ y

y = 21 ÷ 1.73

y = 12.14

tan 30 = x÷ 12

0.6 x 12 = x

x = 7.2

The probability that he will pull out a yellow block it 1/4.

Step-by-step explanation:

There are 4 blocks in the bag, each a different color. Since there is only one yellow out of 4 different blocks, the fraction would be 1/4.

Answer:

  f(x) = (π-2)x^2/4

Step-by-step explanation:

The area of the triangle is ...

  A = 1/2(x)(x) = (1/2)x^2

The hypotenuse of the triangle is x√2, so the radius of the circle is x/√2. That means the area of the semicircle is ...

  A = 1/2πr^2 = (π/2)(x/√2)^2 = (π/4)x^2

The shaded area is the difference between the semicircle area and the triangle area.

  f(x) = (π/4)x^2 -(1/2)x^2

  f(x) = (π-2)x^2/4

Answer:

1 : 15

2: 12

3: 52

4: 27.3

Step-by-step explanation:

For #1:

if line m and n are perpendicular then they will create right angles

Right angles have a measure of 90 degrees

That being said we can find the measure of the missing angle by subtracting the measure of the known angle (75) from 90

so k = 90 - 75

90 - 75 = 15

Hence k = 15.

For #3 ( very similar to #1, only difference is the values of the angles )

so R = 90 - 38

90 - 38 = 52

Hence, R = 52

For #2 and #4

Complementary angles have a sum of 90°

So like the previous questions we can find the measure of the missing angle by subtract the measure of the given angle from 90

∠V = 90 - 78

90 - 78 = 12

Hence ∠V = 12

∠Y = 90 - 62.7

90 - 62.7 = 27.3

Hence ∠Y = 27.3

Answer:

3/700

Step-by-step explanation:

Let

x = the quantity

3/7% of x

= 3/7 ÷ 100 * x

= 3/7 × 1/100 * x

= (3*1)/(7*100) * x

= 3/700 * x

= 3/700x

3/7​% of a quantity = 3/700 of the quantity

Answer:

The space remaining in the truck is 1,276 cubic feet

Step-by-step explanation:

Given that the dimensions of the haul of the moving truck are;

The length of (the haul) of the moving truck = 16 feet

The width of (the haul) of the moving truck = 10 feet

The height of (the haul) of the moving truck = 8 feet

The number of boxes in the truck = 2 boxes

The dimensions of the boxes in the truck = 2 feet cubes

From the given dimensions, we have;

The volume of the boxes, [tex]V_{boxes}[/tex] = 2 ft.³ + 2 ft.³ = 4 ft.³

The volume of the haul, [tex]V_{haul}[/tex] = 16 feet × 10 feet × 8 feet = 1,280 ft.³

The amount (volume) of space remaining, V = [tex]V_{haul}[/tex] - [tex]V_{boxes}[/tex]

∴ V = 1,280 ft.³ - 4 ft.³ = 1,276 ft.³

The amount of space remaining, V = 1,276 ft.³

Answer:

13

Step-by-step explanation:

Once again we are looking at inscribed angles and intercepted arcs. Like stated previously an inscribed angle is equal to half its intercepted arc

That being said we want to create an equation to solve for x

The equation would be 7x + 5 = 192/2

We now solve for x

step 1 simplify

192/2=96

now we have 7x + 5 = 96

step 2 subtract 5 from each side

5 - 5 cancels out

96 - 5 = 91

7x = 91

step 3 divide each side by 7

7x/7 = x

91 / 7 = 13

we're left with x = 13

Answer:

The last expression.

Step-by-step explanation:

The last expression is not a polynomial because x is in the denominator of the second term.

Answer:

[tex]4x^2+\frac{5}{x} -6[/tex]

Step-by-step explanation:

A rule for polynomials, is that if they have variables, the powers should be positive whole numbers. Basically, this means you cannot divide by a variable, but in option 4, second term, you are dividing 5 by x, which is the same as[tex]5*x^{-1}[/tex]. This means you are not raising the variable to a positive power, which means the whole 4th option is not a polynomial.

Answer:

Step-by-step explanation:

You have the right answer

========================================================

Work Shown:

p = number of items sold

855 = cost per item

855p = total revenue = total amount of money earned

6780 = total expenses

profit = revenue - expenses = 855p - 6780

profit = 855p - 6780

------------------

Now plug in p = 250

profit = 855p - 6780

profit = 855*250 - 6780

profit = 213,750 - 6,780

profit = 206,970 dollars

This is the profit the company makes in one month if p = 250 items are sold.

The CEO earns 15% of this profit, so,

15% of 206,970 = 0.15*(206,970) = 31,045.50

The CEO earns $31,045.50

Answer: 5 5/7

Step-by-step explanation:

Number of pizza bought = 20

Fraction of pizza ate = 2/7

Therefore, the number of pizzas that have been eaten will be:

= Fraction of pizza eaten × Number of pizza bought

= 2/7 × 20

= 40/7

= 5 5/7

Therefore, 5 5/7 pizza have been eaten
