Answer:

170

Step-by-step explanation:

19 45 - 16 55

For convenience, let's find the lapse from 17 00 till 19 45, it's simple 2 hours and 45 mins.

Now add the 5 mins we neglected (from 16 55 to 17 00).

That's 2 hours and 50 mins

1 hour = 60 mins

2 hours = 120 mins

2 hour 50 mins = 170 minutes

Step-by-step explanation:

Given, 

Radius of the cylinder = 3cm

Height of the cylinder = 3cm

Therefore, 

Lateral surface area of the cylinder

$= 2\pi rh$

$= 2\pi \times 3 \times 3 {cm}^{2}$

$= 2\pi \times 9 {cm}^{2}$

$= 18\pi {cm}^{2}$

Hence,

The required value in the green box will be 18 (Ans)

Jerry’s rhombus has a base of 15 inches and a height of 9 inches. Charlene’s rhombus has a base and a height that are 13 the bas

neonofarm [45]

Answer: The area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.

Step-by-step explanation:

I will assume that the exercise says " $\frac{1}{3}$ times the base and height of Jerry’s rhombus".

The area of a rhombus can be calculated with the following formula:

$A=b*a$

Where "b" is the length of the base and "a" is the altitude or the height.

Then, you can calculate the area using the formula shown above.

Therefore, you get:

1. Jerry's rhombus:

$A_1=(15\ in)(9\ in)\\\\A_1=135\ in^2$

2. Charlene's rhombus:

$A_2=(\frac{1}{3}*15\ in)(\frac{1}{3}*9\ in)\\\\A_2=(5\ in)(3\ in)\\\\A_2=15\ in^2$

Dividing the area calculated, you get:

$\frac{135\ in^2}{15\ in^2}=9$

Therefore, you can conclude that the area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.

ANEK [815]

Answer:

$372.330

Step-by-step explanation:

if 1 mile = $0.45 and you want to find out 827.4 miles

you should multiple $0.45 × 872.4

1 mile : $0.45

827.4 × $0.45 = 372330

827.4 : $372.330
