The lateral area of that prism consists of 4 rectangles.
h = 0.3 dm = 30 cm.
The lateral area:
A = ( a + b + c + c ) · h
A = (  5 + 3  + 4 + 4 ) · 30
A = 16 · 30 = 480 cm²
Answer: The lateral area of the prism is 480 cm².

Answer:JKL and ∠RST are complementary.

m∠JKL = 36° and m∠RST = ( x + 15)°.

Find the value of x and the measure of ∠RST .

complementary angles are two angles whose sum is 90°

36%2Bx+%2B+15=90°

51%2Bx+=90°

x+=90-51°

x+=39°

->the measure of ∠RST== ( 39 + 15)=54°

0.8% of 150 is what numbers and how do you write the equation with a variable in it.
Tanzania [10]

Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: \frac{0.8}{100} * 150 = x

2. Now, let's solve for x!

  • \frac{0.8}{100} * 150 = (0.008)(150)
  • (0.008)(150) = \frac{6}{5}
  • \frac{6}{5} = 1\frac{1}{5}
  • 1\frac{1}{5} = 1.2
  • 1.2

Therefore, 0.8% of 150 is 1.2!

Answer:

Yes

Step-by-step explanation:

They are exact and you can't mess up or accidentally slide the compass or straightedge around. This is just my opinion though.
