Answer:

91in^2

Step-by-step explanation:

SA of base =  7x7 = 49in^2

SA of each triangle = 1/2 x 7 x 3 = 10.5in^2

SA of all 4 triangles = 10.5 x 4 = 42in^2

SA Total = 49 + 42.= 91inch^2

Every time Martina orders Chinese food, she gets egg drop soup. So, she decides to learn how to make it herself. Her recipe call
MrRa [10]

Answer:

2 cartons

Step-by-step explanation:

Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.

Next, we need to find what we need to know, how many fluid ounces are in a cup? <em>There are 8 fluid ounces in 1 cup!</em>

Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).

<em>8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces</em>

So! Martina needs 64 fluid ounces of broth to be able to create her recipe!

<em>But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!</em>

<em>64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons</em>

Melina needs to buy 2 cartons of broth to be able to complete her recipe.

Hope this Helps! :)

What do you call it when a plane comes down in garbage heap
natita [175]

It is called "trash landing". :)

This is a show of word play which sounds similar to “crash landing” (trash/crash), crash landing is actually an organized landing made by an airplane because of a crisis containing a fast approaching or continuous danger to the well being and activity of the flying machine, but in this case as the plane land in garbage the word “crash” is replaced by “trash” giving a humorous meaning to the phrase.

Hope this helped :)

A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s2, what is their final velocity aft
igomit [66]

<u>Statement</u><u>:</u>

A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s².

<u>To </u><u>find </u><u>out:</u>

The person's final velocity after 3 s.

<u>Solution</u><u>:</u>

  • Initial velocity (u) = 3.7 m/s
  • Acceleration (a) = 2 m/s²
  • Time taken (t) = 3 s
  • We know, the equation of motion,
  • v = u + at
  • Putting the values in the above equation, we get,
  • v = 3.7 m/s + 2 m/s² × 3 s
  • or, v = 3.7 m/s + 6 m/s
  • or, v = 9.7 m/s

<u>Answer</u><u>:</u>

The final velocity is 9.7 m/s in the direction of the motion.

Hope you could understand.

If you have any query, feel free to ask.
