help!!! Find the lateral surface area of
the following square pyramid:

Answers

Given:

A square base pyramid with base length 6 cm and the slant height is 4 cm.

To find:

The lateral surface area of the given square pyramid.

Solution:

The lateral surface area of the given square pyramid is equal to the areas of 4 congruent triangles with base 6 cm and height 4 cm.

Area of a triangle is:

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

So, the area of one triangle or one side of the given pyramid is:

[tex]A_1=\dfrac{1}{2}\times 6\times 4[/tex]

[tex]A_1=\dfrac{24}{2}[/tex]

[tex]A_1=12[/tex]

Now, the lateral surface area of the given square pyramid is 4 times the area of one triangle.

[tex]LA=4A_1[/tex]

[tex]LA=4(12)[/tex]

[tex]LA=48[/tex]

Therefore, the lateral surface area of the given square pyramid is 48 cm².

Answer: 48

Step-by-step explanation: 4*6/2, and the multiply by 4 for all of the sides

If the card above is the product of Emily's and Ros's ages, state their ages, respectively. ​

Answers

Answer:

Given expression:

xy + 3x + 8y + 24

You may factor this as follows:

xy + 8y + 3x + 24 = y(x + 8) + 3(x + 8) = (x + 8)(y + 3)

We have the product of x + 8 and y + 3 and we can state that:

Ok first you need to find the radius of the cone.

Since you’re given the circumference 3.14, we can use the formula for circumference 2piR to find the radius.

3.14=2(3.14)r
R=0.5

Now that you have the radius, you can find the volume of the cone

Since you’re using 3.14 for pi, the volume will be this: V=1/3(3.14)r^2 (Height)

V= 1/3(3.14)(0.5)^2(1.5)
V=0.3925

5. An extension ladder is extended 32 feet to rest
against a wall. The bottom of the ladder is 6 feet
from the base of the wall, as shown.
32 ft.
Which of the following is closest to the distance
from the top of the ladder to the base of the wall?

Answers

Answer:

Option A

Step-by-step explanation:

As shown in the figure ABC,

AC = Length of the ladder

BC = Distance between the base of the ladder and the wall

AB = Distance from the top of the ladder and the base of the wall

By applying Pythagoras theorem in the given right triangle ΔABC,

AC² = AB² + BC²

(32)² = h² + (6.5)²

h² = 1024 - 42.25

h = √(981.75)

h = 31.33

h ≈ 31 feet

Therefore, Option A will be the correct option.

danny is installing a fence around his rectangular yard. His yard is 20feet by 45feet. If the fence cost 25 per foot based on the area what is the cost?

Answers

Answer: Find the perimeter of the yard ( the distance around the yard).

A rectangle has two sides of each dimension.

The perimeter is 20 + 20 + 45 + 45 = 130 feet.

Now multiply the total feet by the cost per foot:

130 feet x 25 per foot = $3,250 total.

Step-by-step explanation:

Answer:

$225

Step-by-step explanation:

The area to be fenced in is 20 ft by 45 ft, or 900 ft^2.  But "25 per foot based on the area" is illogical.  Please ensure that you have copied this problem down accurately, and be sure to provide units of measurement:  did you mean $25 per square foot, or per foot, or what?

The fencing cost is usually dependent on the unit cost and the length of the yard perimeter.  The perimeter is P = 2L + 2W, which here is P = 2(45 ft) + 2(20 ft), or 130 ft.  If the fencing is 25 cents per foot, $130 ft of fencing would come to $32.50.

Answers

Answer:

The table that has a consistent proportionality between Y and X of 2 is choice 2.

Step-by-step explanation:

Because the proportionality between X and Y is 2, that means for each x value, the corresponding y value will be twice as big. The only option that meets this requirement is choice 2, so that is the correct answer.

Mr. Ramirez purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under the age of 12.

Part A: Which system of equations represents the given scenario? Let a represent adults and c represent children.

A.10a + 15c = 20
a + c = 225

B.10a + 15c = 225
a + c = 20

C.15a + 10c = 225
a + c = 20

D.15a + 10c = 20
a + c = 225

Part B: What is the solution to the system of equations?
A.5 adults and 15 children
B.10 adults and 10 children
C.15 adults and 5 children
D.9 adults and 9 children

Answers

Answer:

Part A) C

Part B) A

Step-by-step explanation:

For part B I solved for a (adults) which then I got 5

I will attach an image of my work for part b

sorry for the poor quality picture

The system of equations that represents the given scenario is a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let a represent the number of adult tickets and c represent the number of children's tickets.

The total number of tickets purchased is 20, so we have:

a + c = 20

The cost of an adult ticket is $15 and the cost of a children's ticket is $10. The total cost of the tickets is $225, so we have:

15a + 10c = 225

Therefore, the system of equations that represents the given scenario is:

a + c = 20

15a + 10c = 225

Now let us solve a and c values by using substitution method.

a=20-c

Now substitute in equation 15a + 10c = 225

15(20-c)+ 10c = 225

300 - 15c + 10c = 225

-5c = -75

c = 15

Substituting c = 15 into the first equation, we get:

a + 15 = 20

a = 5

Therefore, the system of equations that represents the given scenario is

a + c = 20, 15a + 10c = 225 and the solution to the system of equations is a = 5 (adults) and c = 15 (children).

A stereo normally priced at ​$690 is on sale for 20​% off. Find the discount and the sale price.

Answers

Answer:

Discount = $138

Sale price = $552

Step-by-step explanation:

Discount =  20% of 690

Sale price  = 100% - 20% = 80% of 690

Discount)

20% = 0.2

0.2 x 690 = 138

Discount = $138

Sale price)

Method 1:

80% = 0.8

0.8 x 690 = 552

Sale price = $552

Method 2:

We know the discount = $138

So subtract the discount from the original price:

690 - 138 = 552

Sale price = $552.
