Find the surface area of this triangular prism

Mathematics
1 answer:
Karo-lina-s [1.5K]3 years ago
7 0

Answer:

This may not be the numbers but just follow the way in how i did it hope it helps!!!

Step-by-step explanation:

SA= 2lw x 2lh x 2wh

Length - 5m

Width - 4m

Height - 6m

= 2 (5 x 4)+2 (5 x 6)+2 (4 x 6)

=2 ( 20)+2 (30)+2 (24)

= 40 + 60 + 48

=148

The dimensions of a second rectangular prism that will have the same surface area will be the below:

Length - 6m

Width -  5m

Height - 4m

SA = 2lw + 2lh + 2wh

= 2(6 x 5)+2 ( 6 x 4) +2 ( 5 x 4)

=2(30)+2 (24)+2 (20)

=60 + 48 + 40

= 148

Which equation represents the line that passes through the points (2, 4) and (1, -3)?
zhannawk [14.2K]

Answer:

y = 7x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (1, - 3)

m = \frac{-3-4}{1-2} = \frac{-7}{-1} = 7, thus

y = 7x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 4), then

4 = 14 + c ⇒ c = 4 - 14 = - 10

y = 7x - 10 ← equation of line

Please help I don’t understand
nikitadnepr [17]

Answer:

5 people

Step-by-step explanation:

For each people Ms Hernandez bring to the zoo, she will pay $15.50, so if she go alone, 1×15.50, if she go with one person, 2×15.50, with three 3×15.50, and keep growing this way. The price each person pay is constant and equal to 15.50, and what will determine the final price is the number of people. Also remember that she always will have to pay $ 10 on parking, so you can write an equation with this:

15.50x +10 = y, as x being the number of people and y being the final price.

She have $100, so this is the max she can spend. Two know the number of people she can bring to the zoo, put 100 in place of y and find the value of x:

15.50x + 10 = 100

15.50x = 100 - 10

15.50x = 90

x = 90/15.50

x = 5.8

But there's no way to bring 0.8 person, so the max she can bring are 5 people, including her

Find the slope of the line that contains<br> the points (6, 8) and (2, 1).
yawa3891 [41]

Answer:

7/4 or 1.75

Step-by-step explanation:

Assuming this is a linear function, you can use the slope formula of change in y-values divided by change in x-values. Take your y-values (8 - 1), which is seven. Then take your x-values (6-2), which is equal to 4. Then your slope is just 7/4 or 1.75.

Answer this really quick
ivann1987 [24]

Answer:

the equation is y = ax + b (a ≠ 0)

see in the graph, the line passed through (0;3) and (1;5)

=>b = 3

   a + b = 5

<=> a = 2

     b = 3

=> the equation is y = 2x + 3
