Answers

Answer: The third choice.

A net is a flat version of a three dimensional shape. Imagine that you have a tissue box. If you cut along the edges and laid out the pieces, you would have the net of the shape. The third choice gives the correct net that would fold back up to a rectangular solid with the given dimensions.

Final answer:

The correct net for a rectangular prism with width 3 cm, height 8 cm, and length 7 cm would consist of three rectangles side by side with a width of 3 cm, where the first and third rectangles have a length of 8 cm and the middle one 7 cm, and three additional rectangles underneath the middle one with widths of 8 cm, 3 cm, and 8 cm respectively.

Explanation:

We are trying to match a net with a solid figure, specifically a rectangular prism with dimensions of width 3 cm, height 8 cm, and length 7 cm. To find the correct net, we need to consider the faces of the rectangular prism and how they would lay out flat.

The correct net for this prism would need three rectangles side by side for the sides with a width of 3 cm. The lengths of these side rectangles should be equal to the height of the prism, which is 8 cm. The middle rectangle represents the base or the top of the prism and should have a length equal to the length of the prism, which is 7 cm. Moreover, attached to this middle rectangle, there should be three flaps representing the remaining faces of the prism; two with widths equal to the height (8 cm) and one width equal to the width of the prism (3 cm).

The only net description that matches our rectangular prism dimensions is: "A net is shown with 3 rectangles attached side by side all with width 3 centimeters. The length of the first and third rectangle is 8 centimeters and the middle is 7 centimeters. Underneath the middle rectangle are 3 more rectangles with the same length but widths of 8 centimeters, 3 centimeters, and 8 centimeters."

The cost of 7 drinks is $16.38. What is the cost of each drink?

$1.54
$1.88
$2.34
$2.73

Answers

the answer to thus question is $2.34

The cost of each drink if 7 drinks cost $16.38 is $2.34.

What is Division?

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that the cost of 7 drinks is $16.38. Therefore, the cost of each of the drink will be:

Cost of each drink = Cost of all the drinks / Number of drinks

= $16.38 / 7

= $2.34

Hence, the cost of each drink is $2.34.

How much compound interest is earned on $2050 at 4% interest for 3 years, compounded annually? Give your answer in dollars and cents. Don’t forget to subtract P from A.

Answers

To solve for the amount + interest for compounding interest you will use this formula:
[tex]A = P ( 1 + \frac{r}{n}) ^{nt} [/tex]

Where A = Accrued amount
P = Principal amount
r = rate in decimal
t = number of years
n = compounding periods per unit of time
Your given:
P = $2050
r = 4% or 0.04
t = 3 years
n = 1 per yr
Now we insert that into your formula:
[tex]A = P ( 1 + \frac{r}{n}) ^{nt} [/tex]
[tex]A = 2050 ( 1 + \frac{0.04}{1}) ^{1.3} [/tex]
[tex]A = 2050 ( 1 + 0.04) ^{3} [/tex]
[tex]A = 2050 ( 1.04) ^{3} [/tex]
[tex]A = 2050 (1.124864 ) [/tex]
[tex]A = $2305.97 [/tex]

Now to get the interest just remember that:
I = A - P
I = $2,305.97 - $2,050
I = $255.97
So that is equal to 255 dollars and 97 cents

$255.97 is the correct answer

what is the intersection points of f(x)=2x+7 and g(x)=x^2-1

Answers

intersecting means f(x)=g(x)
2x+7=x²-1
x²-2x-8=0
(x-4)(x+2)=0
x=4, or x=-2
when x=4, f(x)=g(x)=15
when x=-2, f(x)=g(x)=3
so the intersecting points are (4, 15) and (-2, 3)

The price of a pair of headphones is $49.99 before tax. Ron bought the headphones for a 50% discount. He then paid sales tax of 8% on the discounted price.

Part A: How much did Ron pay in sales tax? Show all work and steps in your solution.
Part B: What is the total amount that Ron paid for the headphones? Show all work and steps in your solution.

Answers

Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00

Part B:
Total price: $24.99 + $2.00 = $26.99

456 000 has been rounded to the nearest thousand. What was the smallest possible number this could have been?

Answers

The smallest possible number could have been 455,500

Answer:

The smallest possible number this could have been = 455500

Step-by-step explanation:

456000 has been rounded to the nearest thousand.

If the value is more than 456500 the value rounded to the nearest thousand is 457000.

If the value is less than 455500 the value rounded to the nearest thousand is 455000.

In between 455500 and 456500 the value rounded to the nearest thousand is 456000.

So, The smallest possible number this could have been = 455500

The histogram will show that the mean time is greater than the median time of 7.4 minutes. The shape of the histogram can be approximated with a normal curve. The histogram will show that most of the data is centered between 6 minutes and 9 minutes. ITS A, D, E, I JUST TOOK THE QUIZ!!!

Answers

The histogram is especially useful in comparing mean and median values of a variable. We have that 5.5+6+7+10+7.5+8+9.5+9+8.5+8+7+7.5+6+6.5+5.5=111.5 Since there are 15 values, their mean is 111.5/15=7.43 which is very close to the mean. We also have that 7 onservations are lower than 7.4 while 8 are bigger than 7.4; hence, the diagram is rather balanced and not left-skewed. We cannot tell immediately which one is larger since the values are too close. Any such random process can usually be approximated to a greater or smaller degree by a normal curve; the more points, the better. The histogram shows this (it is kind of a discrete normal curve); all points except 4 will be in this interval of bars.

find the slope of the line that passes through each set of points

Answers

You didn't provide any points, but you'd need only two per line.

If the points are (a,b) and (c,d), the slope would be (d-b)/(c-a).

Slope really means "how much does the y change when the x advances by 1?"

In above two points, the y-difference is d-b. However, the x-difference is not 1, but it is c-a. If we divide by c-a, we get the y difference as if x advanced by 1.

D(4,5) E(-3,-9)

Let (4,5) = (x₁ , y₁) and (-3,-9) = (x₂ , y₂)
Slope = (y₂ - y₁) / (x₂ - x₁)
Slope = (-9 -5) / (-3 -4)
Slope = 14/7
Slope = 2

OR
Let (4,5) = (x₂ , y₂) and (-3,-9) = (x₁ , y₁)
slope = (5 - (-9)) / (4 - (-3))
slope = 14/7
slope = 2

A 100 N horizontal force is applied to a 5.0 kg box causing the box to move at a constant speed of 3.0 m/s. What is the value of the friction force on the box?

Answers

The friction force must be acting to oppose the 100 N applied force, so it should be -100 N.
The reason for this is that the box is moving at a constant speed, with no acceleration. For there to be no acceleration, there must also be zero net force.

The sum of r and t is equal to 42. Let r = 25. What is the value of t?

Answers

r + t = 42
r = 25

Plug in 25 for r

(25) + t = 42

Isolate the t by subtracting 25 from both sides

t + 25 (-25) = 42 (-25)
t = 42 -25
t = 17

Hope this helps

Since r = 25, t must equal a number that, when added to 25, equals 42.

42 - 25 = 17. t must equal 17.

17 + 25 = 42.

Dennis can load the car in 28 min. If Andy helps him it takes 21 min to load the car how long will it take Andy alone?

Answers

let the load car = y , and Andy will take time x (min.) to load the car
So,
    The rate of Andy to load the car = y/x

And we given that: Dennis load the car in 28 min.
So,
    The rate of Dennis to load the car = y/28

If both are loading the car in time = t = 21 min
then:
         y = (y/x) t + (y/28) t     ⇒ divide all equation by y and substitute with t
∴      1 = (21/x) + (21/28)     ⇒ multiply all equation by 28x
        28x = 21*28 + 21x
        28x - 21 x = 588
        7x = 588
∴      x = 84 min.

Which mean Andy will take 84 min. to load the car alone.

If the circumference of a circle measures 3/2 π cm, what is the area of the circle in terms of π?

Answers

Final answer:

The area of the circle with a circumference of 3/2 π cm is 9/16 π cm².

Explanation:

The question is asking about finding the area of a circle when the circumference is given. The formula to find the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle. Given that the circumference is 3/2 π cm, we can use this information to find the radius.

From the circumference equation, r = C/2π = (3/2π)/ 2π = 3/4 cm. Having the radius, we can then use the formula for the area of a circle, which is A = πr². As a result, the area of the given circle is π(3/4)² cm² which simplifies to 9/16 π cm².
