Answer:

$3.40

Step-by-step explanation:

Final answer:

To determine the cost Geraldo will pay for 4 pounds of apples, we find the cost per pound from his previous purchase and multiply by the desired weight. At $0.85 per pound, Geraldo will pay $3.40 for 4 pounds of apples.

Explanation:

Last week, Geraldo bought 7 pounds of apples for $5.95. To find out how much he will pay for 4 pounds of apples this week at the same price, we first need to calculate the cost per pound of the apples. We do this by dividing the total cost by the total weight in pounds from the previous purchase.

The cost per pound is $5.95 divided by 7 pounds, which equates to approximately $0.85 per pound (rounding to two decimal places).

So, for 4 pounds of apples, Geraldo will pay 4 times $0.85, which results in a total of $3.40.

Therefore, Geraldo will pay $3.40 for 4 pounds of apples.

Step-by-step explanation:

The cone is sliced by a plane, which produces a smaller cone on top.  This cone is similar to the original cone.  Therefore:

R / H = r / h

2 / 8 = r / 4

r = 1

The radius of the circle at the intersection of the plane and the cone is 1.

To find the radius of the circle at the intersection of the plane and the cone, we start by understanding the geometry of the cone and the slicing plane.

Given:

- Cone height ( h = 8 )

- Cone radius ( r = 2 )

- The plane slices the cone halfway along its height, so the distance from the vertex to the plane is  [tex]\( \frac{8}{2} = 4 \)[/tex].

Let's denote:

- ( R ): Radius of the circle at the intersection of the plane and the cone.

At height ( h ) from the vertex of the cone, the radius ( R ) of the circle formed by the intersection with the plane is related to the similar triangles formed by the cone and the slice plane.

The ratio of corresponding sides of similar triangles gives us:

[tex]\[ \frac{R}{r} = \frac{h - 4}{h} \][/tex]

Substitute the given values:

[tex]\[ \frac{R}{2} = \frac{8 - 4}{8} = \frac{4}{8} = \frac{1}{2} \][/tex]

Now, solve for ( R ):

[tex]\[ R = 2 \cdot \frac{1}{2} = 1 \][/tex]

Therefore, the radius of the circle at the intersection of the plane and the cone is [tex]\( \boxed{1} \).[/tex]

Answer:

[tex]x\geq 0[/tex]  Domain

y = 40+1.5x  relationship

[tex]y \geq 40[/tex]  range

Step-by-step explanation:

The domain is the amount of carpet installed.  We can install zero carpeting or any positive amount of carpeting.

[tex]x\geq 0[/tex]

Now writing the equation for the cost

They charge 40 flat rate plus 1.50 per square foot

y = 40+1.5x

Let x = 0

y = 40+0

Even if they do not install anything, they still charge 40 dollars flat rate.  That is the minimum amount we have to pay.  As x increases, the cost will increase.

That is the range, or the values of y

[tex]y \geq 40[/tex]

We want to get the equation for the total cost and its domain and range.

The equation is:

c(x) = $40 + $1.50*x

domain: x > 0ft^2

range: y > $40.

First, let's get the equation.

We know that the carpet installer charges a flat rate of $40 plus $1.50 per square feet.

So if he/she works for x square feets, the cost is:

c(x) = $40 + $1.50*x

This is the cost equation.

Now we want to find the domain and range of this. The domain is given by the possible values of x that we can input in the function. Here we know that x must represent the number of square feet that are worked on, so it only must be a number larger than zero.

x > 0ft^2.

While the range is the set of the possible outputs.

The smallest possible output is the one we get when we evaluate the function in the smallest value of the domain, so we get:

y > $40.

These two define the domain and range.

Answer:

10 peaches and 5 bananas

Step-by-step explanation:

To solve the problem increase the cost by adding more peaches and less by adding more bananas

7 peaches = 3.50

8 bananas = 3.20 + 3.50 = 6.70

We need 30 more cents so add three more peaches

10 peaches = 5

5 x 0.4 = 2

2 + 5 = 7

Final answer:

To determine the number of bananas and peaches Samantha bought, we can set up a system of equations and solve for the variables. By using substitution, we find that Samantha bought 5 bananas and 10 peaches.

Explanation:

To determine the number of bananas and peaches that Samantha bought, we can set up a system of equations. Let x represent the number of bananas and y represent the number of peaches. From the given information, we know the cost of each banana is $0.40 and the cost of each peach is $0.50. We can write two equations to represent the total cost of the bananas and peaches:

$0.40x + $0.50y = $7 (equation 1)

x + y = 15 (equation 2)

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

From equation 2, we know that x = 15 - y. We can substitute this value of x into equation 1:

$0.40(15 - y) + $0.50y = $7

Simplifying the equation, we get:

$6 - $0.40y + $0.50y = $7

Combining like terms, we have:

$0.10y = $1

Dividing both sides by $0.10, we get:

y = 10

So, Samantha bought 10 peaches. Substituting this value of y back into equation 2, we can solve for x:

x + 10 = 15

Subtracting 10 from both sides, we get:

x = 5

Therefore, Samantha bought 5 bananas and 10 peaches.

Answer:

  8/12 yard or 2/3 yard

Step-by-step explanation:

The sum of the two lengths is ...

  5/12 yd + 3/12 yd = (5+3)/12 yd = 8/12 yd

This fraction can be reduced by removing a factor of 4 from numerator and denominator.

  8/12 yd = 2/3 yd

If the arm portions are end-to-end, the total length is 2/3 yard.

X=32 and Y=12

The two numbers are 32 and 12

Step-by-step explanation:

Let the number be represented by X and Y

X = 20 + Y-------- equation 1

3X - Y = 84------- equation 2

solving the equation by substitution;

we substitute equation 1 into equation 2, we have;

3(20+Y)-Y = 84

expanding the bracket;

60 + 3Y - Y = 84

60 + 2Y = 84

2Y = 84 - 60

2Y = 24

divide both sides by 2;

2Y/2 = 24/2

Y = 12

from equation 1, we can find X by using the value of Y;

X = 20 + Y

X = 20 + 12

X = 32

Answer:

0.4 U.S dollars-4 I guess

The stock purchased for $77 grew by 17.9%, which equals an increase of $13.78. Therefore, the current stock price is $90.78.

To solve this problem, we need to calculate the percent increase of the stock's price. A percent increase of 17.9% means that the stock price has increased by 17.9% of the original price. To calculate the amount of the increase, we multiply the original price ($77) by the percent increase (17.9%), remembering to convert the percentage to a decimal (0.179).

So, $77 times 0.179 equals ~$13.78. This is the amount by which the stock price has increased. To find the new price of the stock, we add this increase to the original price, which gives us $77 (Original price) + $13.78 (Increase) = $90.78, so the stock is worth $90.78 now.

A = 6 * 14

A = 84

[tex]r^{}} = \sqrt{\frac{V}{\pi h }[/tex] is the equation correctly shows the radius.

Option B

Step-by-step explanation:

The cylinder’ volume (density) indicates how much amount of materials it can able to carry or how much amount of material it can immerse in it. The formula for volume of cylinder is given as:

                      [tex]V = \pi r^{2}h[/tex]

where

V = volume of cylinder

r = radius of cylinder

h = height of cylinder

In order to find radius following simplifications are done:

⇒[tex]V = \pi r^{2}h[/tex]

Keep the factor 'r' in one side and keep other in one side as below,

⇒ [tex]\frac{V}{\pi h } = r^{2}[/tex]

Taking square root on both sides,

⇒[tex]\sqrt{r^{2}} = \sqrt{\frac{V}{\pi h }[/tex]

⇒[tex]r^{}} = \sqrt{\frac{V}{\pi h }[/tex]

Therefore, option b is correct as [tex]r^{}} = \sqrt{\frac{V}{\pi h }[/tex].

Option A: [tex]y=-\frac{1}{2} x+5[/tex] is the equation of the line.

Explanation:

It is given that the equation has a slope is [tex]m=-\frac{1}{2}[/tex]

It also contains the point [tex](8,1)[/tex]

We need to find the equation of line in slope - intercept form.

First, we shall determine the value of y - intercept(b).

Let us substitute the slope [tex]m=-\frac{1}{2}[/tex] and the point [tex](8,1)[/tex] in the slope - intercept form [tex]y=mx+b[/tex] , we get,

[tex]1=-\frac{1}{2} (8)+b[/tex]

Simplifying, we have,

[tex]1=-4+b[/tex]

Adding both sides of the equation by 4, we have,

[tex]1+4=b[/tex]

     [tex]5=b[/tex]

Thus, the y - intercept is [tex]b=5[/tex]

Now, substituting the slope [tex]m=-\frac{1}{2}[/tex] and the y - intercept [tex]b=5[/tex] in the slope - intercept form [tex]y=mx+b[/tex] , we get,

[tex]y=-\frac{1}{2} x+5[/tex]

Thus, the equation of the line is [tex]y=-\frac{1}{2} x+5[/tex]

Hence, Option A is the correct answer.
