ANSWER

36 cubic inches.

EXPLANATION

The volume of a square pyramid is calculated using the formula:

[tex]V = \frac{1}{3} {l}^{2} \times h[/tex]

where l² is the area of the base and h= 6 inches is the height of the square pyramid.

We substitute the values into the formula to get,

[tex]V = \frac{1}{3} \times 18 \times 6 \: {in}^{3} [/tex]

We simplify to get:

[tex]V = 6 \times 6 =3 6 {in}^{3} [/tex]

Therefore the volume of the square pyramid is 36 cubic inches.

[tex]x = 20[/tex] or [tex]x = -5[/tex]

Step-by-step explanation:

To solve the quadratic equation we must factor the expression

Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.

You can verify that these numbers are -20 and 5

[tex]-20 +5 = -15\\\\-20 * 5 = -100[/tex]

Then the polynomial factors are

[tex](x-20) (x + 5) = 0[/tex]

 The zero product property says that if two terms [tex]a * b = 0[/tex] then

[tex]a = 0[/tex] or [tex]b = 0[/tex]

So

[tex](x-20) = 0[/tex] or [tex](x + 5) = 0[/tex]

[tex]x = 20[/tex] or [tex]x = -5[/tex]

Or  [tex]m=\frac{\delta y}{\delta x}[/tex]

Looking at the table, the change in each value of x is 10 (10 to 20 to 30 to 40).

Also, the change in each valueof y is -3 (20 to 17 to 14 to 11).

Note: change in y is negative since it is DECREASING.

Hence the slope would be -3/10

Answer:

Final answer is 10.5 gallons of water.

Step-by-step explanation:

Given that Joe is filling the washing machine to wash clothes. After one minute, there are 1.75 gallons of water in the washing machine. After two minutes, there are 3.5 gallons of water in the machine. After three minutes, there are 5.25 gallons in the machine. Now we need to determine If this pattern continues then about how many gallons of water will be in the washing machine after six minutes.

Look at the pattern of volume of the water at given minutes.

We see that 1.75 is added each minute.

then required equation of volume is

V=1.75t

So for t=6 minutes, volume is given by

V=1.75*6=10.5

Hence final answer is 10.5 gallons of water.

The amount of water in the washing machine after six minutes can be determined using an arithmetic sequence formula. The machine fills at a constant rate of 1.75 gallons per minute, so after six minutes, there will be 10.5 gallons of water in the machine.

The question provided concerns a pattern of water filling a washing machine, which falls under the subject of arithmetic sequences in mathematics. To determine how many gallons of water will be in the washing machine after six minutes, we need to recognize the sequence and apply the appropriate formula.

To solve this problem, we note that the washing machine fills at a constant rate of 1.75 gallons per minute because the amount of water increases by 1.75 gallons with each passing minute (1.75 gallons at minute one, 3.5 gallons at minute two, which is 1.75 x 2, and 5.25 gallons at minute three, which is 1.75 x 3).

Mathematically, this can be represented as an arithmetic sequence with the first term a1 = 1.75 gallons and the common difference d = 1.75 gallons. The nth term of an arithmetic sequence is given by the formula an = a1 + (n - 1)d. So, to find the amount of water after six minutes, substitute 6 for n, which yields:

a6 = 1.75 + (6 - 1) times 1.75

a6 = 1.75 + 5 times 1.75

a6 = 1.75 + 8.75

a6 = 10.5 gallons

Therefore, after six minutes, there will be 10.5 gallons of water in the washing machine if the pattern continues.

Answer:

0.64 seconds.

Step-by-step explanation:

When it hits the ground h(t) = 0.

0 = -16t^2 + 4t + 4

-4(4t^2 - t -1) = 0

t = [-(-1) +/- sqrt (1 - 4*4*-1)] / 8)

t = 0.64, -0.39

answer is 0.64 seconds.

it will take the baseball 0.64 seconds to hit the ground.

The equation representing the height is:

h = -16t² + 4t + 4

When the baseball hits the ground, the height will be 0. That is,h =0

Substitute h =0 into the equation above

0 = -16t² + 4t + 4

Rearrange the given equation to be:

16t² - 4t - 4 = 0

Solving the quadratic equation above:

t = -0.39 and 0.64

Since time cannot be negative, it will take the baseball 0.64 seconds to hit the ground.

Answer:

Jack took 6 minutes and 33 seconds longer to complete the race.

Step-by-step explanation:

54 minutes minus 47 minutes would equal 7 minutes longer, but Jack was not as far into the minute when he completed it as Ben was when he completed it, so the difference in time is actually going to be a bit less than 7 minutes. So the difference is going to be 6 minutes and the number of seconds between 39 and 12, with 39 going past the minute, that is. That equals out to 33 seconds, so the total difference in time is 6 minutes and 33 seconds.

Answer: The Order of Operations is very important when simplifying expressions and equations. The Order of Operations is a standard that defines the order in which you should simplify different operations such as addition, subtraction, multiplication and division.

Step-by-step explanation:

Given:

f(x)=4x-3

f(x) +g(x) =9x +4

To find:g(x)

Solution:

f(x) + g(x) =9x +4

Replacing f(x) with its value.

4x -3 +g(x) = 9x +4

=> g(x) = 9x+ 4 -(4x-3)

=> g(x) = 9x+4 -4x +3

=> g(x) = 5x +7

Hence;

Option A g(x)=5x+7 is the answer.

Answer:

Lani's mom will need 80 ft of fencing

Step-by-step explanation:

We are looking for the perimeter of the garden. We know that the garden is 22 ft x 18 ft. This means that we can find the perimeter using this equation

[tex]22(2)+18(2)=80[/tex]

Here all you need to know to solve this exercise:

1) When you write the equation of a line in the form

[tex]y=mx+q[/tex]

the slope is the coefficient m.

2) When you know that the line passes through a point [tex](x_0,y_0)[/tex] and has slope m, the equation of the line is given by

[tex]y-y_0=m(x-x_0)[/tex]

3) Let [tex]m_1,m_2[/tex] be the slopes of two lines. If the lines are parallel, then [tex]m_1=m_2[/tex]. If the lines are perpendicular, then [tex]m_1m_2=-1[/tex].

In the first exercise, using point 1, you can see that the slope of the given line is 2. We want a parallel line passing through the given point. So, our line has the same slope, and its equation is (see point 2)

[tex]y-2=2(x+1) \iff y = 2x+4[/tex]

Similarly, in the second exercise, the original slope is 1/3, so the perpendicular slope is -3. The equation will be, imposing the passage through the given point,

[tex]y-6 = -3(x-0) \iff y = -3x+6[/tex]

Answer:

see explanation

Step-by-step explanation:

19

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c yje y- intercept )

y = 2x - 3 is in this form with slope m = 2

• Parallel lines have equal slopes, hence

y = 2x + c ← partial equation of parallel line

To find c substitute (- 1, 2) into the partial equation

2 = - 2 + c ⇒ c = 2 + 2 = 4

y = 2x + 4 ← equation of parallel line

20

Rearrange x - 3y = 5 into slope- intercept form

Subtract x from both sides

- 3y = - x + 5 ( divide all terms by - 3 )

y = [tex]\frac{1}{3}[/tex] x - [tex]\frac{5}{3}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, so

y = - 3x + c

The line passes through (0, 6) ⇒ c = 6

y = - 3x + 6 ← equation of perpendicular line

Answer:

(a) What is the probability that you roll a 6?

1/6

(b) What is the probability that you either roll a 6 or do not roll a 6?

1

(c) What is the probability that you don't roll a 6?

5/6

Step-by-step explanation:

(a) What is the probability that you roll a 6?

In a 6- sided cube, a 6 occurs only once. That is only one face is labelled 6. Therefore, the probability that you roll a 6 is;

(number of faces labelled 6)/(totals number of sides) = 1/6

(b) What is the probability that you either roll a 6 or do not roll a 6?

The probability of rolling a 6 was found to be, 1/6.

On the other hand, the probability of not rolling a 6 is;

(number of faces not labelled 6)/(totals number of sides) = 5/6

Therefore, the probability that you either roll a 6 or do not roll a 6 is;

1/6 + 5/6 = 1

These two events are mutually exclusive and exhaustive.

(c) What is the probability that you don't roll a 6?

The probability of not rolling a 6 is;

(number of faces not labelled 6)/(totals number of sides) = 5/6

We have 5 faces not labelled 6 out of 6 possible faces or outcomes

2. Plug in 25 into the formula

3. [tex]c = 25\pi[/tex]

Answer

[tex]25\pi[/tex]

The circumference of the circle is approximately 78.54 cm.

To find the circumference of the circle, we first need to find the length of the hypotenuse (which is also the diameter of the circle) using the Pythagorean theorem. Then, we can use the formula for the circumference of a circle, which is C = π * d, where C is the circumference and d is the diameter.

Let's calculate it step by step:

Step 1: Find the length of the hypotenuse using the Pythagorean theorem:

[tex]a^2 + b^2 = c^2[/tex]

where a and b are the lengths of the chords (24 cm and 7 cm, respectively), and c is the length of the hypotenuse (diameter).

[tex]24^2 + 7^2 = c^2\\\\576 + 49 = c^2\\\\625 = c^2[/tex]

c = √625

c = 25 cm

Step 2: Calculate the circumference using the formula C = π * d:

C = π * 25 cm

C ≈ 78.54 cm

The circumference of the circle is approximately 78.54 cm.

Answer:

linear:  slope =10,y-intercept=25

Step-by-step explanation:

Yes, a linear equation can be used to model the situation because for any two given pints, there is a constant value of 10 for change in (p) over change in (n).

The slope is given by:

[tex]m=\frac{Change\:in\:p}{Change\:in\:n}[/tex]

Using (1,35) and (5,75) from the table, we have:

[tex]m=\frac{75-35}{5-1}[/tex]

[tex]m=\frac{40}{4}=10[/tex]

Therefore the slope is 10.

Using the formula

[tex]y=mx+b[/tex], and the point (1,35) we have:

[tex]35=10(1)+b[/tex]

[tex]\implies 35-10=b[/tex]

[tex]\implies 25=b[/tex]

Therefore the y-intercept is 25.

Each shirt cost $7  and each pair of shorts cost $17 .

Step-by-step explanation:

let shirts be represented as x

let shorts be represented as y

Younger brother spent $79 on 4 new shirts and 3 pairs of shorts.

4 x + 3 y = $79    .......equation 1

Older brother purchased 7 new shirts and 8 pairs of shorts and paid a total of $185.

7 x + 8 y = $185  .......equation 2

multiply equation 1 by 7 and equation 2 by -4 and add both equations to get the value of y.

7 × (4 x + 3 y = $79)     ⇒             +28 x + 21 y = $553

-4 × (7 x + 8 y = $185)  ⇒             -28 x - 32 y = - $740

                                                          0   - 11 y   = - $187     ⇒  -11 y   = - $187

y = [tex]\frac{- $187}{- 11}[/tex]   ⇒   y = $17

shorts = y = $17

put value of y in equation 1
