Find the surface area of the triangular prism. A triangular prism. The base is a right triangle with base 1 foot, height 2 feet and third side 2 point 2 feet. The height of the prism is 3 feet.

Answers

Answer 1

Answer:

17.6ft²

Step-by-step explanation:

The formula for calculating the surface area of a triangular prism is expressed as shown below:

SA= bh + pH

b= base of the triangle

h- height of the triangle

p= perimeter of the triangle

H= height of the prism

Given b = 1foot

h = 2feet

perimeter of the triangle = sum of all its sides = 1ft + 2ft + 2.2ft

p = 5.2ft

H = 3ft

Substituting the values into the formula for finding the surface area:

SA = 1(2)+5.2(3)

SA = 2+15.6

SA = 17.6ft²

The surface area of the triangular prism is  17.6ft²

Answer:

1,950 ft

Step-by-step explanation:

it is a compound shape, thus it is made up of a square and a triangle

you can find the area of the square by 30 x 50 and the area of the triangle by 30 as the height and 65 - 50 as the base, and when you add it together you get 1,950

the perimeter of a circle is 132 calculate its diameter​

Answers

Answer:

42

Step-by-step explanation:

The perimeter of circle is same as it’s circumference.

Circumference = π * D

132 = 22/7 * D

22D = 7 * 132

22D = 924

D = 924/22

D = 42

Answer:

42.0

Step-by-step explanation:

For this question we are given the circumference of a circle which is 132 and we are asked to find diameter of the circle. We need to utilise one important formula which the circumference of a circle formula

Circumference of a circle = π × d

We need to make 132 equal to the circumference of a circle formula so then we can work out the diameter by forming an equation to solve for the diameter so,

⇒ Form the equation

→ π × d = 132

⇒ Divide both sides by π to isolate d

→ d = 42.0169049763

The diameter of the circle with a perimeter of 132 is 42.0 to 1 decimal place

A ball is thrown into the air with an upward velocity of 13 ft/s. Its height h in feet after t seconds is given by the function h = −2t^2+ 13t + 24. In how many seconds does the ball reach its maximum height?

Answers

Answer:

3.25 seconds

Step-by-step explanation:

The maximum height will occur when the velocity of the ball reaches zero in the air.

Velocity is given as the derivative of height, dh/dt.

The equation of height given is:

[tex]h = -2t^2+ 13t + 24[/tex]

Differentiating height, h, with respect to time, t, we have:

[tex]v = dh/dt = -4t + 13[/tex]

When v = 0:

[tex]0 = -4t + 13\\\\=> 4t = 13\\\\t = 13 / 4 = 3.25 secs[/tex]

Therefore, it will take 3.25 seconds for the ball to reach maximum height.

Which statement about the parabola is not true?A. The focus lies on the axis of symmetry.B.The directrix of the parabola is parallel to the axis of symmetry.C. Each point on the parabola is equidistant from the directrix and the focus

Answers

Answer:

Option B

The directrix of the parabola is parallel to the axis of symmetry

Step-by-step explanation:

The directrix of the parabola is not parallel to the axis of symmetry. It is as a matter of fact, perpendicular to it.

A parabola is actually a set of points that are equidistant from a given point, the focus, and a given line the directrix.

The axis of symmetry is a line that divides the parabola into two equal halves and it always passes through the focus.

The directrix of the parabola is always perpendicular to this axis of symmetry as they always intersect at right angles.

We want to see which one of the given statements is false. We will see that the false one is B: "The directrix of the parabola is parallel to the axis of symmetry"

So in a parabola, we define the axis of symmetry as the vertical line that divides the parabola in two equal parts.

For a general parabola:

y = a*x^2 + b*x + c

The line of symmetry is at:

x = -b/2a

While we know that in a parabola the directrix is a horizontal line.

So the axis of symmetry and the directrix are perpendicular lines.

Then the statement that is false is B: "The directrix of the parabola is parallel to the axis of symmetry"

Angelica started with half a tank of gas in her car, and she used of that. Write an equation in the text box. Solve to show how much of a full tank she used.

Answers

Ans

Step-by-step explanation:

Let one full tank = x

Then by the given statement, Angelica started with x/2

Suppose she used half of that, then,

x/4. So that x/4 - x/2 = x/4

This implies that she travelled half the distance she would have, using a full tank.

Suppose her destination requires 3 full tanks, then she would stop three times for a refill.

Answer:

Step-by-step explanation:

it has to be a negative graph so a and d aren't right and the y intercept is 3 so c is right

Answer:

the answer is C

Step-by-step explanation:

1st step to write the slope intercept form then first u need to find the two points that ur going to use, then u get the slope

FIND THE SLOPE:

point 1: (2,0)

point 2: (0,3)

slope= y2-y1/x2-x1

s= 3-0/0-2

s= -3/2

2nd step is to find the y-intercept, to find that u take the slope intercept form which is y=mx+b

m=slope

b=y-intercept

and now substitute the variable for the known value

pick any of the two points, so u can substitute the variable X and Y

x=2

y=0

b=-3/2

0=2(-3/2)+b

solve to find B

distribute 2

2(-3/2)=-6/2 or -3

0=-3+b

and now add 3 to both sides

0+3=-3+3+b

b=3

now the slope intercept formula is y=-3/2x+3

to check the answer u can substitute the X and Y of one of the points and see if u get the solution as 0 or 3 (it depends on which point u chose)

Find the equation of the line parallel to 2y-3x= 4 and passing through the point (6,7)

Answers

Answer:

We have equation of a line:

2y - 3x = 4 => y = (3/2)x + 4

The equation of the line that is parallel to above line and passes through the point (6, 7) would have form y = ax + b, and

a = 3/2

6a + b = 7

=> b = 7 - 6a = 7 - 6 x 3/2 = 7 - 9 = -2

=> The equation of that line: y = (3/2)x - 2

Describe when you would need to solve a system of linear equations, instead of a single linear equation

Answers

Answer:

See explanation below

Step-by-step explanation:

A system of linear equations is a system that is formed when you have two or more variables, for example:

[tex]x=2y+z\\3y-4x=7y+2z\\2y+z=4x+3y[/tex]

In this case, we have 3 equations with 3 variables in total (x, y and z). Thus, we would need to solve a system of linear equations (they are linear because none of the variables have exponents).

On the other side, a single linear equation has only one variable that we need to find, for example:

[tex]3x=\frac{5}{3}[/tex]

In this case we would just have to solve for x

[tex]3x=\frac{5}{3} \\9x=5\\x=\frac{5}{9}[/tex]

Thus, we need to solve a system of linear equations when we have more than one variable (and more than one equations) as opposed to when we have just one variable and a single equation (single linear equation)

A waitress serves $950. Worth of dinners and recieves &95.00 in tips how much less in tips did she receive if she had gotten her 15% of the cost of meals

Answers

Answer:

She receives $47.5 less

Step-by-step explanation:

Now, the first thing to do here is to calculate what 15% if the total amount is

That would be 15/100 * 950 = $142.5

The amount she receives less is thus $142.5 -$95 = $47.5

Answer:

The amount less that she received than if she had received 15% of the cost of the meal is $47.5

Step-by-step explanation:

Here we have the amount of dinners served by the waitress = $950

Amount received in tips = $95.00

Amount the waitress would have received if she had gotten 15% of the cost of meals served = 15/100 × $950 = $142.5

Therefore, since she received $95.00, the amount less that she received than if she had received 15% of the cost of the meal is thus;

$142.5 - $95 = $47.5.
