Answer 1
Area of a prism is area of cross section x length. Area of triangle is 1/2 base times height. Surely that makes it easy for you now m8.
Answer 2

Answer and Step-by-step explanation:

First, lets write down the volume of an equilateral triangular prism.

The volume of a triangular prism is as follows:

\(V = \frac{1}{2} * b * h * l\)

Where:

b = base length (edge)

h = height

l = length.

\(V = \frac{1}{2} * 4*10*2\sqrt{3} = 40\sqrt{3} = 69.2820\)

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.​

Answers

To solve this problem, let's denote the mass of the dog as D and the mass of the lion as L.

We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:

0.80D = 0.24L

We are also given that the mass of the lion is 105 kg more than the mass of the dog:

L = D + 105

We can use these two equations to find the values of D and L.

Substituting the value of L from the second equation into the first equation:

0.80D = 0.24(D + 105)

Now, let's solve for D:

0.80D = 0.24D + 0.24(105)

0.80D - 0.24D = 25.2

0.56D = 25.2

D = 25.2 / 0.56

D ≈ 45

Now that we have the value of D, we can find the value of L by substituting it back into the second equation:

L = 45 + 105

L = 150

Therefore, the total mass of the dog and the lion is:

D + L = 45 + 150 = 195 kg

So, the total mass of the dog and the lion is 195 kg.

Answers

Answer:

  4320 in²

Step-by-step explanation:

You want the total surface area of the 3-tiered pedestal shown in the figure.

Front area

The area of the front of the stand is that of the three 20-inch wide pedestals stacked on top of each other for a total height of 11 +15 +7 = 33 inches. That area is ...

  A = LW = (20 in)(33 in) = 660 in²

Lateral area

Lateral area of the pedestal is the product of its depth (20 in) and the perimeter of the front. The front perimeter is the equivalent of the perimeter of a rectangle 60 inches wide and 15 inches high, which is ...

  P = 2(60 +15 in) = 150 in

Total area

The total surface area of the stand is the sum of front and back areas and the lateral area:

  SA = 660 in² +660 in² +(20 in)(150 in) = 4320 in²

The total surface area of the stand is 4320 square inches.

Answers

Answer:

y = 12

Step-by-step explanation:

the equation is

y = 3x

You find the constant or proportionality by put y/x

(15,45) is in the form (x,y)  The x is 15 and the y is 45.  Put this in the form y/x and you get 45/15 or 3.  3 is the constant of proportionality.

y = 3x

y = 3(4)

y = 12

Zahra needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged her $66 for parts. The total was $184.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

Answers

Answer:

25

Step-by-step explanation:

1st Step, Find how much she paid for 4.75 hours

184.75 - 66 = 118.75

2nd Step, find how much she did in 1 hour

118.75/4.75 = 25

25 dollars per hour

After solving the equation, we found that the cost of labor per hour is $25.

Let us denote the cost of labor per hour as = "x";

The total cost consists of two components: the labor cost and the cost of parts.

We know that : the technician worked for 4.75 hours and charged $66 for parts, the total-cost is $184.75,

Using the equation:

Total Cost = Labor Cost + Parts Cost,

Substitute the given values,

$184.75 = 4.75x + $66,

Now, solve for "x",

4.75x = $184.75 - $66,

4.75x = $118.75,

Divide both sides by 4.75,

x = $118.75/4.75,

x = $25,

Therefore, the cost of labor per-hour (x) is $25.
