Find the volume, in cubic inches, of a right rectangular prism with the measurements below. Length: 3/2" Width: 5/2" Height: 4

Answers

Answer:

Step-by-step explanation:

The volume of a rectangular prism can be calculated by multiplying the area of its base by its height.

Mathematically, we have

The volume of prism = base area X  height

At this point, it is important to note that a rectangular prism is a solid shape that has its base as a rectangle; so the area of its base, is the same thing as the area of a rectangle.

Where base area = length X breadth

hence, volume = length X breadth X height

volume = 3/2 X 5/2 X 4 = 15 cubic inches

What is the surface area?​

Answers

Answer:

The total area is 685

Step-by-step explanation:

First get the area of the square; the area of the square is the height times the width. Because its a square all of its sides are equal, 15 times 15 equals 225. Next we go to figuring out the triangles´ area; the formula to figure out a triangles area is 0.5 times height times width. Because there are 4 of the exact same triangles we only have to figure out one and we have the area for each of them. 0.5 times 20 times 15 equals 115, with that information we are able to obtain all the information we need to discover the total area.

The area of the square: 225

The area of each of the triangles: 115

If there are 4 exact triangles of 115 then that equals all the triangles together to be 460, then add the square 460 plus 225 equals 685.

Malik bought a pack of erasers for $3.50 and some pencils for $0.99 each. He paid a total of $10.43. Which equation can be used to find the number of pencils Andrew bought? \

Answers

Answer:

The equation that can be used to find the number of pencils Andrew bought is:

x=(c-3.50)/0.99

Step-by-step explanation:

With the information provided, you can say that the total amount paid would be equal to the price of the pack of erasers plus the price per pencil for the number of pencils purchased, which can be expressed as:

c=3.50+0.99x, where:

c is the total cost

x is he number of pencils purchased

Now, you can solve for x in order to find the equation to calculate the number of pencils Andrew bought:

c-3.50=0.99x

x=(c-3.50)/0.99

According to this, the answer is that the equation that can be used to find the number of pencils Andrew bought is:

x=(c-3.50)/0.99

write an equation for a function that has vertical asymptotes at x=3 & x=-10

Answers

Answer:

[tex] \frac{5}{ {x}^{2} + 7x - 30} [/tex]

Step-by-step explanation:

We can write a rational function.

We need to make sure our denominator both have zeroes at 3 and 10.

Set an equation equal to zero to find the function

[tex]0 - x = 3[/tex]

[tex]0 - x = - 10[/tex]

[tex]0 - ( - 3) = = 3[/tex]

[tex]0 - 10 = 10[/tex]

So we would represent that's as

[tex]x - 3[/tex]

and

[tex]x + 10[/tex]

Multiply the two binomial together.

[tex](x - 3)(x + 10) = {x}^{2} + 7x - 30[/tex]

Let our numbetator be any interger.

Use any equation as long as the quadratic is the denominator and the interger is the numerator.

[tex] \frac{5}{ {x}^{2} + 7x - 30 } [/tex]

Hello!

We can solve the quadratic by using the Quadratic Formula.

Standard form of a Quadratic: [tex]ax^2 + bx +c= 0[/tex]

Quadratic Formula: [tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex]

Given our equation: [tex]x^2+5x+3 = 0[/tex]

a = 1b = 5c = 3

Plug it into the formula and solve:

[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-5\pm\sqrt{5^2 - 4(1)(3)}}{2(1)}[/tex][tex]x = \frac{-5\pm\sqrt{25-12}}{2}[/tex][tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex]

This cannot be simplified further. The answer is [tex]x = \frac{-5\pm\sqrt{13}}{2}[/tex].

Sam kicks a ball from the ground with a starting velocity of 32 feet per second. The ball soars into the air, arcs down with parabolic motion, and lands back on the ground. Write an equation to describe the height of the ball as a function of time, using h(t)=-16t^2+vt+s. PLS HELP!!!!!!

Answers

Answer:

The function that describes the height of the ball in time is  [tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex].

Step-by-step explanation:

Let suppose that ball experiments a free fall motion, which means that the ball is accelerated because of gravity and gravitational acceleration can be considered constant since height reached by the object is too small in comparison with the radius of the Earth. Therefore, we can assume that ball is accelerated uniformly.

Hence, the kinematic formula for the height of the ball ([tex]h(t)[/tex]), in feet, is described below:

[tex]h(t) = s + v\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)

Where:

[tex]s[/tex] - Initial height with respect to the ground, in feet.

[tex]v[/tex] - Initial velocity, in feet per second.

[tex]t[/tex] - Time, in seconds.

[tex]g[/tex] - Gravitational acceleration, in feet per square second.

If we know that [tex]s = 0\,ft[/tex], [tex]v = 32\,\frac{ft}{s^{2}}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that describes the height of the ball in time is:

[tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex] (2)

Someone please help me lol !

Answers

Answer:

x = 9

Step-by-step explanation:

Formula

The secant and tangent lines bear the following relationship

(tangent line )^2 = the outside secant line * length of the whole line

Givens

tangent line = 15

outside secant line = x

length of whole secant line = x + 16

Solution

15^2 = x ( x + 16)

15^2 = x^2 + 16x

225 = x^2 + 16x

x^2 + 16x - 225 = 0

Answer and Discussion

The equation has two factors.

(x - 9)(x + 25) =0

x + 25 has no meaning. There cannot be a negative length in this level of geometry.

The answer is x - 9 = 0

1- highest was 98 lowest was 74!

Answer:

1: The highest score is 98, the lowest score is 74.

2: 55% of the scores are greater than 84

Step-by-step explanation:

Solution 1-1:

Starting from the top left and going from left to right row by row we compare the largest number we come across with the current number we are inspecting.

Starting with 92 then we look at 88, 92 is greater than 88 so we keep 92, next is 95, 95 is greater than 92 so we keep 95, next is 74, 95 is greater than 74 so we keep 95 and so on until we have compared all of the numbers. We are left with 98

Solution 1-2:

Using a similar method to finding the greatest number we go through the list of numbers in search of the smallest number. Starting with 92 we then look at 88, 88 is less than 92 so we keep 88. Next is 95, 88 is less than 95 so we keep 88. Then 74, 74 is less than 88 so we keep 74 and so on. We are left with 74

Solution 2:

There is a total of 20 numbers in the table. By comparing the numbers in the table to 84, we can determine that 11 numbers are greater than 84.

By dividing 11 by 20 we get 0.55 which is equal to 55%
