A triangular prism and two nets are shown:

leonid [27]

The net for a triangular prism consists of
2 identical triangles, here all nets have sides 5,12, and 13.
3 rectangles, all with a common dimension: the height H=14 of the prism.

Each of the 3 rectangles should have dimensions
H=14 plus one of the following:
each of 5, 12, 13 corresponding to one side of the base (triangle).

So the dimensions of the rectangles are
5x14, 12x14, 13x14

And dimensions of the triangles are
5,12 and 13.

The total surface area is therefore
(5+12+13)*14 + 2*(5*12/2)
=420+60
=480.

There is only one net that satisfies this condition.

Is the open sentence 3z=2z+5 true or false when z=5? A. True B. False

inna [77]

Hey there!

If z = 5

we replace "z" with "5"

So, let's test out the problem to see if it is true or false

Problem becomes: $3(5) = 2(5) + 5$

Let's work this out

$3(5) = 15$

Problem becomes: $15 = 2(5) + 5$

$2(5) = 10$

Problem becomes: $15 = 10 + 5$

$10 + 5 = 15$

So, therefore it looks like this statement/ sentence is $True$ !

Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost

vitfil [10]

Answer:

The answer is $8.00.

Step-by-step explanation:

First, you have to find how much for each app so you have to divide by 3 :

3 apps = $2.40

1 app = $2.40 ÷ 3

1 app = $0.80

Next, you have to multiply it by 10 :

1 app = $0.80

10 apps = $0.80 × 10

10 apps = $8.00
