Answer:

63 in^2

Step-by-step explanation:

Area = base x height

Base: 7

Height: 9

9 x 7 = 63

Answer:

63 inches squared or [tex]63in^{2}[/tex]

Step-by-step explanation:

The answer is 63 inches squared.

The area of a parallelogram is always base times height.

In this case, the base is seven and the height is nine.

To find the area, we must multiply nine by seven

We get 63

But, we are multiplying inches and inches together

When we multiply something by itself, it becomes squared

Since we are multiplying inches by inches, it becomes inches squared

Therefore, the area of the shape is 63 inches squared, or

[tex]63in^2[/tex]

Answer:

[tex]\frac{5}{4}[/tex]

Step-by-step explanation:

we can find the zero of the linear function

F(x)= -4x+5 ,by solving the equation -4x+5 = 0

Solving the equation:

-4x+5 = 0

⇔ -4x = -5

[tex]\Longleftrightarrow x=\frac{-5}{-4} =\frac{5}{4}[/tex]

⇔ x = 1.25

is that algebra?

Answer:

11,000 paid $14 for reserved seats.

25,000 paid $6 for general admission.

Step-by-step explanation:

First, we need to establish the system of equations:

x= number of people that pay $14

y= number of people that pay $6

14*x + 6*y= $304,000

x + y= 36,000

Now, we isolate x in one equation and substitute it in the other one:

x= 36,000 - y

14*(36,000 - y) + 6y = 304,000

504,000 - 8y = 304,000

200,000 = 8y

25,000 = y

x= 36,000 - 25,000

x= 11,000

11,000 paid $14 for reserved seats.

25,000 paid $6 for general admission.

Answer:

2 1/4 pints

Step-by-step explanation:

create a ratio with the fact there are 16 ounces in 1 cup

let 'p' = number of pints

16 = 36

 1         p

cross-multiply:  16p = 36

                            p = 36/ 16, which is 9/ 4, or 2 1/4

Answer:

Your answer is 3x = 15

Step-by-step explanation:

3x = 15

Since 3 is being multiplied by x, we divide both sides by 3.  3x/3 cancels out, and you're left with x.

15/3 = 5

x = 5

This is my take using algebraic methods.

Answer:

Option A and option B applies

Step-by-step explanation:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Marcus has opened a savings account where the yearly interest rate is 10%. He deposits $1,000 to start the account.

This means, respectively, that: [tex]r = 0.1, P = 1000[/tex]. So

[tex]A(t) = 1000(1 + \frac{0.1}{n})^{nt}[/tex]

Option A:

[tex]n = 1[/tex]. So

[tex]A(t) = 1000(1 + \frac{0.1}{1})^{t}[/tex]

[tex]A(t) = 1000(1.1)^{t}[/tex]

So option A applies

Option B:

[tex]n = 12[/tex]. So

[tex]A(t) = 1000(1 + \frac{0.1}{12})^{12t}[/tex]

0.1/12 = 0.008. So

[tex]A(t) = 1000(1 + 0.008)^{12t}[/tex]

[tex]A(t) = 1000(1.008)^{12t}[/tex]

So option B also applies.

The other options will not apply.

Answer:

the length of the fence is 37.7 feet

Step-by-step explanation:

The computation is given below:

Given that

Diameter = 12 feet

So, the radius is the half of the diameter = 6 feet

Now the length of the fence is

= 2 × π × r

= 2 × 3.14 × 6

= 37.68 feet

= 37.7  feet

Hence, the length of the fence is 37.7 feet

The length of the fence will be 37.7 feet.

Based on the information given, we are informed that the circular swimming pool is 12 feet across and is enclosed by a fence. We want to calculate the perimeter.

The perimeter of a circle will be:

= πd

where,

π = 3.142

d = 12 feet

Therefore, the length of the fence will be:

=πd

= 3.142 × 12

= 37.7 feet

The length of the fence is 37.7 feet.

Answer:the perimeter of the rectangle =A) (−14w+14v) centimeters

Step-by-step explanation:

Step 1

The perimeter of a Rectangle is given as 2 (l+ w)

If Length = 2v+3w centimeters.

and width =5v-10wcentimeters

Then Perimeter =2 (2v+3w + 5v-10w)

Perimeter=2(7v -7w)

Perimeter= 14v - 14w or can be written as -14w +14v

Answer:

Step-by-step explanation:

The conventional way to work these problems is to make use of the formulas for areas of a triangle, rectangle, and semicircle. If you've used these formulas for a while, you recognize that they give you certain relationships that may make these problems easy to do mentally.

__

1. The area of a triangle is half the product of height and width, so is equivalent to the area of a rectangle either half as high, or half as wide. We note that the width of the sail is 5 cm, so half that is 2.5 cm--exactly the same as the height of the boat's hull. That means we can add the height of the sail to the length of the boat, and the total area can be considered to be the same as that of a rectangle that is

  2.5 cm high × (12 cm + 6 cm) long = (2.5)(18) cm² = 45 cm²

__

2. The usual formula for the area of a circle is ...

  A = πr²

When expressed in terms of diameter, this becomes ...

  A = π(d/2)² = (π/4)d²

Then the area of a semicircle is half that, or (π/8)d². This is equivalent to the area of a rectangle that is "d" wide and "π/8·d" high. That is, the approximate area of the semicircle is that of a rectangle 4 cm high by (π/8·4 cm) = π/2 cm wide. In other words, the semicircle effectively adds π/2 cm to the left end of the 6 cm central rectangle of the figure.

As discussed above, the area of a triangle is equivalent to the area of a rectangle half as high. In this figure, the triangle is 10-6 = 4 cm wide, so can be considered to contribute 4/2 = 2 cm to the right end of the 6 cm central rectangle.

If we consider π ≈ 3, then the approximate area of the figure is ...

  (4 cm)(3/2 cm + 6 cm + 2 cm) = (4)(9.5) cm² = 38 cm²

__

The exact value is 4(8+π/2) = 32+2π ≈ 38.283 cm².
