Answer:

180 sq ft

Step-by-step explanation:

12 x 15 = 180

The total amount of carpet Mrs. Ownes bought for her rectangular room of 12 ft by 15 ft is 180 sq ft.

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

A=a\times b

Here, (a)is the length of the rectangle and (b) is the width of the rectangle

Mrs. Owens laid carpet in a rectangular room, 12 ft by 15 ft. Here, the length of the rectangular carpet for the room should be 15 ft and width should be 12 ft.

Thus, the area of the carpet is,

[tex]A=15\times12\\A=180\rm\; ft^2[/tex]

Thus, the total amount of carpet Mrs. Ownes bought for her rectangular room of 12 ft by 15 ft is 180 sq ft.

Answer:

D. 80

Step-by-step explanation:

Given:

f(x) = 5x - 4,

g(x) = x² - 1

Required:

(g o f)(-1)

SOLUTION:

(g o f)(-1) = g(f(-1))

Plug in -1 for x into the function, f(x) = 5x - 4:

g(f(-1)) = g(5(-1) - 4)

= g(-5 - 4)

= g(-9)

Plug in -9 for x in the function, g(x) = x² - 1

g(-9) = (-9)² - 1

= 81 - 1

= 80.

Therefore, (g o f)(-1) = g(f(-1)) = 80

D. 80 is the correct answer.

Step-by-step explanation:

because integers are positive and negative numbers

Answer:

She is not correct

Step-by-step explanation:

This is the answer because:

1) We know that an integer is either a negative or positive number which has no fractional components/ no relation to fractions.

2) This means that an integer should not be expressed in the x/y form, also known as the fraction form.

3) Integers should always be a whole number that is negative or positive. An integer should never be a "part" of a number.

Therefore, 3/5 in not an integer

Answer:

s = 9t + 18

Explanation:

Set up your equation

s - 15 = 9t + 3

Now get s by itself by adding 15 to both sides

s + 0 = 9t + 3 + 15

s = 9t + 18

If you know the value of t, plug that into the equation to solve further.

Answer:

-14y + 34

Step-by-step explanation:

Step 1: Write out equation

6(5 - 3y) + 4(y + 1)

Step 2: Distribute

30 - 18y + 4y + 4

Step 3: Combine like terms

-14y + 34

Answer:

34-14y

this is simplifed

Step-by-step explanation:

I take it that you're trying to solve for the variable (x), so by using the order of operations (PEMDAS), the first step is to add 40 to both sides of the equation as addition cancels out subtraction.

[tex] - 32x - 40 = 0[/tex]

[tex] - 32x = 40[/tex]

From there you will divide by -32 and simply the fraction.

[tex]x = - \frac {40}{32} [/tex]

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

I hope this helps, but please let me know if this is not what you're trying to do.

Step-by-step explanation:

(4 + 4)/2 = 8/2= 4

(8 + 6)/2= 14/2= 7

(4, 7) the midpoint

Answer:

the answer got that would be -4

We have to simplify and get the value of x from this inequality given:

Given inequality,

[tex]3(x - 4) > 5x + 2[/tex]

Now let's simplify by using distributive property,

[tex]3x - 12 > 5x + 2[/tex]

We need to find x, so let's isolate x to the letter side of the inequality for calculation at ease.

[tex]3x - 12 - 5x - 2 > 0[/tex]

[tex] - 2x - 14 > 0[/tex]

Now, dividing -2 from both sides.

Note : As we are dividing a negative number from both sides, the sign of the inequality will be reversed.

[tex] \dfrac{ - 2x - 14}{ - 2} > \dfrac{0}{ - 2} [/tex]

[tex]x + 7 < 0[/tex]

Now subtracting -7 from both sides,

[tex]x + 7 - 7 < 0 - 7[/tex]

[tex]x < - 7[/tex]

Or, Interval of the equal [tex](- \infin, -7 ][/tex]

Answer:

it's A :)

Step-by-step explanation:

can I have brainlest please

Answer:

Step-by-step explanation:

The question is incomplete. Find the complete question a=below;

A golf ball is hit with a club from the ground on a flat surface. The height of the ball, h(t), in feet, t seconds, after it was hit can be modeled by the function h(t)=40t-16t2. After how many seconds does the golf ball strike the ground?

The ball strikes the ground when the height h(t) = 0. To get the time wen the golf ball strikes the ground, we will substiute h = 0 into the modeled equation and calculate t as shown;

h(t)=40t-16t2

0 h(t)=40t-16t2

40t-16t² = 0

add 16t² to both side

40t-16t²+16t² = 0+16t²

40t = 16t²

40 = 16t

divide both sides by 16

t = 40/16.

t = 2.5secs

Hence the golf ball hit the ground after 2.5secs

Answer:

when the ball is hit as 0 second it has a height of 0 feet (because it hasnt done anything yet). The ball's height increases until it reaches its maximum height of 40 feet after 1.25 seconds (40t= 2.5/2). The balls height then decreases until it reaches 2.5 seconds after it was hit.
