1. Determine the lateral and total surface
area of the pyramid.

(I need full explanation on how to solve

Answers

Answer:

Laterial surface area: 73 cm²Total surface area: 93 cm²

Step-by-step explanation:

The laterial surface area is the sum of the areas of the triangles. There are two triangles with dimensions: base = 4 cm, height = 8cm and two triangles with dimensions: base = 5cm, height = 8.2cm.

The laterial surface area LSA is:

LSA = 2 • ( 4.8/2) + 2 • ( 5 • 8.2/2)

LSA = 4 • 8 + 5 • 8.2

LSA = 73 cm²

The total surface area SA is the LSA plus the area of the base of the pyramid, which is a rectangle with dimensions: 4cm x 5cm:

SA = LSA + 4 • 5

SA = 73 cm + 20 cm²

SA = 93 cm²

Answer:

(v -7)/(5v^2)

Step-by-step explanation:

Cancel common factors from numerator and denominator.

[tex]\dfrac{v^2-49}{20v^3}\times\dfrac{4v^2-24v}{v^2+v-42}=\dfrac{4}{20}\cdot\dfrac{(v-7)(v+7)(v)(v-6)}{v^3(v+7)(v-6)}\\\\=\dfrac{1}{5}\cdot\dfrac{v-7}{v^2}\cdot\dfrac{v(v+7)(v-6)}{v(v+7)(v-6)}=\boxed{\dfrac{v-7}{5v^2}}[/tex]

Which is the vertex point of the equation y = (x - 1)2 - 16

Answers

Answer:

The vertex is at (h, k), which here is (1, -16).

Step-by-step explanation:

Compare the given y = (x - 1)2 - 16 (which should be y = (x - 1)^2 - 16 )

to y = (x - h)^2 - 16.

We can readily see that h = 1 and k = -16.

The vertex is at (h, k), which here is (1, -16).

What is the volume of this rectangular prism?

Jasper built a dollhouse for his younger sister.

A rectangular prism has a length of 24 inches, width of 8 inches, and height of 10 inches. A triangular prism has a triangular base of 24 inches and height of 6 inches. The height of the prism is 8 inches.
Which equation shows how to determine the volume of the dollhouse?
V = 24 (10) (8) + one-half (6) (24) (8)
V = 24 (10) (8) + one-third (6) (24) (8)
V = 24 (10) (8) + one-half (6) (24) (10)
V = 24 (10) (8) + one-third (6) (24) (10)

what two number multiply to 24 and add to -11

Answers

Answer:

8 and 3

Step-by-step explanation:

Brainliest Please

Answer:

One example is x = -8, y = -3

Step-by-step explanation:

Lets make a system of equations.

Let x be the first number and y be the second.

x * y = 24

x + y = -11

Solve for x and substitute.

x = 24/y

24/y + y = -11

24 + y^2 = -11y

y^2 + 11y + 24 = 0

Factor.

(y + 8)(y+3) = 0

So one example is x = -8, y = -3

A company rents out 17 food booths and 24 game booths at the county fair. The fee for a food booth is $50 plus $6 per day. The fee for a game booth is $80 plus $9 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.

Answers

Given that 15 food booths were rented out for ‘d’ days at $100 plus $5 per day. On the food booths only, the company will earn 15($100+$5d) = $1500 + $75d Given that 20 game booths were rented out for ‘d’ days at $50 plus $7 per day. On the game booths only, the company will earn 20($50 + $7d) = $1000 + $140d

The total amount that the company is paid is therefore, $1500 + $75d + $1000 + $140d = $2500 + $215d

2/5 of 35 is 14.So 14 green marbles.

. Find the sum of the infinite series, if it exists.

-270+135-67.5+⋯

Answers

Answer:

-180

Step-by-step explanation:

135/-270 = -1/2

67.5/135 = -1/2

The series is an infinite geometric series with r = -1/2

Since -1 < |r| < 1, the series has a sum

and equals a/(1 - r) a = -270

S = a/(1 - r) = -270/(1 + 1/2) = -270/(3/2) = -180

the question is find the product of -8 and the sum of -2(10x + 3y) and -5(6y -7x)

Answers

Answer:

Step-by-step explanation:

-2(10x + 3y)

-20x -6y [-2 multiplied by 10x = 20x, negative + positive = negative]

-5(6y -7x)

-30y + 35x

-20x -6y -30y +35x

35x - 20x -30y -6y

15x - 36y

Answer = 15x -36y

Answer:

- 120x + 288y

Step-by-step explanation:

Begin by summing the 2 expressions

- 2(10x + 3y) - 5(6y - 7x) ← distribute parenthesis

= - 20x - 6y - 30y + 35x ← collect like terms

= 15x - 36y

Now multiply the result by - 8

- 8(15x - 36y) ← distribute

= - 120x + 288y

3x+5y=27.50 & 6x+3y=27

Answer:

z = 15 degrees, 5z = 75 degrees

Step-by-step explanation:

AYB is 180 degrees

CYD is 90

so the two missing angles sum to 180 - 90 = 90

z + 5z = 90

6z = 90

z = 15

5z = 75
