The cost of filling the planter with soil is $6.24. option C

What is the cost of filling the planter with soil?

Length = 2 ft

Width = 2 ft

Height = 6 ft

Volume of the square based pyramid = ⅓ × length × Width × height

= ⅓ × 2 × 2 × 6

= ⅓ × 24

= 8 cubic feet

Cost of soil per cubic foot = $0.78

Therefore,

Cost of filling the planter with soil = Volume of the square based pyramid × Cost of soil per cubic foot

= 8 × $0.78

= $6.24

Complete question:

A planter in the shape of a square pyramid with dimensions 2 ft by 2 ft by 6 ft is being filled with soil. Soil cost $0.78 per cubit cubic foot What is the cost of filling the planter with soil?

The rug will fit on the floor of her room

Step-by-step explanation:

The floor's area is given as 108

Will the rug fit this area of 108 sq. ft.?? We have to find the area of the rug and if it is less than 108, then definitely it will fit.

The rug is in the shape of a rectangle. The area of a rectangle is length times width.

Given length 10 and width 6, the area is:

Area of Rectangle = 10 * 6 = 60

Area of Rug = 60

Is 60 less than 108?? Yes, definitely!

The rug will fit on the floor of her room

Answer:

x/2=87.2

Step-by-step explanation:

Pip was thinking of a number - Let's call this number x

Pip halve the number - So half of x = x/2  (or 1/2 x)

And gets an answer of 87.2  - x/2=87.2

So your equation would be x/2=87.2

I hope this helps :)

Final answer:

Pip's mystery number is found by taking the equation x / 2 = 87.2, where x is the original number. By solving it, we find that x = 174.4.

Explanation:

Pip is thinking of a number. When Pip halves this number, the result is 87.2. To formulate an equation with x based on this information, we consider that halving a number is equivalent to multiplying that number by 0.5 or dividing it by 2.

Therefore, we can represent the situation with the equation x / 2 = 87.2. This equation states that half of Pip's unknown number (x) equals 87.2.

To solve for x, we multiply both sides of the equation by 2:

x = 87.2 × 2

Which simplifies to:

x = 174.4

This means that Pip was thinking of the number 174.4.

Answer:

Amount of caffeine left after 5 hours = 36 mg

Step-by-step explanation:

We are told that the cup has 310 mg of caffeine originally.

Since it decreases by 35 percent or 0.35 each hour, it means that for each additional hour, the new amount of caffeine would be (1 - 0.35) x previous amount i.e. 0.65 x previous amount. Thus;

After 0 hour, we have; 310 mg

After 1 hour, we have; 310(0.65)

After 2 hours, we have; 310(0.65)(0.65)

After 3 hours, we have; 310(0.65)(0.65)(0.65)

We can see this follows a pattern of;

A(t) = 310(0.65)^(t)

Where;

A(t) is the amount left after t hours

And t is time t hours

Thus, amount left after 5 hours is;

A(5) = 310(0.65)^(5)

A(5) = 310 x 0.11603

A(5) ≈ 36 mg

Answer:

36 mg

Step-by-step explanation:

Answer:

90 pounds, 210 pounds

Step-by-step explanation:

Given:

A storekeeper wants to mix two types of flour to get 300 pounds, so he can sell it by 2.50$ per pound.

He uses flour worth $2.40 a pound with another flour worth $3.00 a pound.

Question:

How many pounds of each does he use?

Solution:

Let pounds of one type of flour mixed = [tex]x[/tex]

Then pounds of another type of flour mixed = [tex]300-x[/tex]

Cost of 1 pound of one type of flour = $2.40

Cost of [tex]x[/tex] pounds of one type of flour = [tex]2.4x[/tex]

Similarly,

Cost of 1 pound of another type of flour = $3

Cost of  [tex]300-x[/tex] pounds of another type of flour = [tex]3(300-x)=900-3x[/tex]

Cost of mixed flour per pound = $2.5

Total cost of mixed flour per pound = $2.5 [tex]\times[/tex] 300 = $750

Cost of [tex]x[/tex] pounds of one type + Cost of  [tex]300-x[/tex] pounds of another type = $750

[tex]2.4x+900-3x=750\\\\ -0.6x+900=750\\ \\ Subtracting\ both\ sides\ by\ 900\\ \\ -0.6x+900-900=750-900\\ \\ -0.6x=-150\\ \\ Minus\ canceled\ by\by\ minus\\ \\ 0.6x=150\\ \\ Dividing\ both\ sides\ by\ 0.6\\ \\ x=90[/tex]

Pounds of one type of flour mixed = [tex]x[/tex] = 90 pounds

Pounds of another type of flour mixed = [tex]300-x[/tex] = 300 - 90 = 210 pounds

Thus, 90 pounds of one and 210 pound of another type of flour mixed.

Answer:

Step-by-step explanation:

Kevin’s verbal score is 610 is 140 points above the mean,which is 470. the standard deviation is 121 so his verbal score is 140/121≈1.16 standard deviations above the mean. Kevins quantitative score of 700 is 150 points above the mean, which is 500. The standard deviation is 148, so his quantitative score is 150/148 ≈ 1.01 standard deviation above the mean.Thus, Kevins verbal score is better than his quantitative score.

Answer:

∠ABC=[tex]70^0[/tex]

Step-by-step explanation:

In the attached diagram,

If Angle ADC =[tex]35^0[/tex]

Since the center of the circle is at B

∠ABC is the angle subtended at the center by arc AC.

∠ADC is the angle subtended at the circumference by arc AC.

Theorem

The angle subtended by an arc at the center of a circle is double the size of the angle subtended by the same arc at the circle's circumference.

Therefore by the theorem above

∠ABC = 2 X ∠ADC

=2 X 35

∠ABC=[tex]70^0[/tex]

Step-by-step explanation:

The percent change in the value of the car from 2006 to 2015 is approximately -66.67%, meaning the car's value decreased by about 66.67% over that time period.

The subject of this problem is percent change, and it is a mathematical concept used to understand the degree of change over time. In this case, the percent change in the value of the car from 2006 to 2015. As per the problem, the value of the car in 2006 was $28,350. In 2015, the value dropped to a third of the original value. Therefore, the value of the car in 2015 was $28,350 / 3 = $9,450.

Now, to find the percent change, you use the formula:

Percent Change = ((New Value - Original Value) / Original Value ) * 100

Substituting the given values in the formula, you get:

Percent Change = (($9,450 - $28,350) / $28,350) * 100

Simplifying that further, you find that the percent change is approximately -66.67%. This means, the value of the car decreased by approximately 66.67% from 2006 to 2015.

Answer:

39 feet

Step-by-step explanation:

In this problem, the height of the football at time t is modelled by the equation:

[tex]h(t)=-16t^2+vt+s[/tex]

where:

s = 3 ft is the initial height of the ball

v = 48 ft/s is the initial vertical velocity of the ball

[tex]-32 ft/s^2[/tex] is the acceleration due to gravity (downward)

Substituting these values, we can rewrite the expression as

[tex]h(t)=-16t^2+48t+3[/tex]

Here we want to find the maximum height reached by the ball.

This is equivalent to find the maximum of the function h(t): the maximum of a function can be found requiring that the first derivative of the function is zero, so

[tex]h'(t)=0[/tex]

Calculating the derivative of h(t), we find:

[tex]h'(t)=-32 t+48[/tex]

And imposing it equal to zero, we find the time t at which this occurs:

[tex]0=-32t+48\\t=-\frac{48}{-32}=1.5 s[/tex]

And substituting back into h(t), we can find the maximum height of the ball:

[tex]h(1.5)=-16\cdot (1.5)^2 + 48\cdot 1.5 +3=39 ft[/tex]

Using the vertical motion model, the time when the football reaches maximum height is calculated to be 1.5 seconds. Substituting this into the model, the maximum height of the football is found to be 39 feet.

To find the maximum height, we consider the vertical motion model h = -16t^2 + vt + s, where v is initial velocity in feet per second and s is the initial height of the football. The information provided include: initial velocity v = 48 feet/sec and initial height s = 3 feet.

The maximum height reached by the football is achieved when the velocity becomes zero (time at which the ball reaches its highest point). This time can be calculated using the formula t = v / (2 * g), with g being half the coefficient of t^2 (g = 16 feet/sec^2 in this case). Substituting v and g gives us approximately t = 1.5 seconds.

We then substitute this time into our initial equation to find the maximum height. This gives: h = -16*(1.5)^2 + 48*1.5 + 3 = 39 feet. Therefore, the maximum height reached by the football is 39 feet.

Equivalent expression are expressions that have equal values, when expanded. The equivalent expression of ln(2x)^4  is 4ln(2) + 4ln(x))

The expression is given as:

[tex]\ln(2x)^4[/tex]

Apply the following logarithmic rule to the above equation

[tex]\ln(a)^b = b\ln(a)[/tex]

So, we have:

ln(2x)^4  = 4ln(2x)

Next, apply the following product rule of logarithm to the above equation

ln(ab) = ln(a) + ln(b)

So, we have:

ln(2x)^4  = 4 * [ln(2) + ln(x)]

Expand the bracket

ln(2x)^4  = 4ln(2) + 4ln(x))

Hence, the equivalent expression of ln(2x)^4  is 4ln(2) + 4ln(x))
