0.45 Km / min and 0.9 Km

note that 1 hour = 60 minutes

divide by 60 to get Km / min

27 Km / hour = \frac{27}{60} = 0.45 Km / min

distance in 2 minutes = 0.45 × 2 = 0.9 Km

*ANSWER ASAP* Earth has a diameter of approximately 7926 miles. Determine the volume of Earth.
frutty [35]

Answer:

Rounding to the nearest whole number, 49 moons can fit in the earth.

Rounding to the tenth place, 50 moons can fit in the earth.

Step-by-step explanation:

To find how approximately how many moons could fit inside the earth, you would need yo find the volumes the earth and the moon.

V = 4/3 π r^3

Earth:

d = 2r

d = 7926 miles

7926 = 2r

3963 miles = r

V = 4/3 π (3963)^3

V = 4/3 π (62240377347)

V = 82987169796π cubic miles

Moon:

d = 2r

d = 2159 miles

2159 = 2r

1079.5 miles = r

V = 4/3 π (1079.5)^3

V = 4/3 π (1257963209.88)

V = 1677284279.83π cubic miles

Now you divide the volume of earth by the volume of moon to find how many moons can fit in earth

82987169796π ÷ 1677284279.83π =

approx 49

URGENT!! A student needs 3 pieces of wire for a science project. The second piece must be 3 times as long as the first. The thir
Marianna [84]

Answer:

Part a) The inequality that represent the situation is

x+(3x)+(6x) \leq 350\ in  

Part b) The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to 35\ inches

Step-by-step explanation:

Let

x------> the length of the first wire

3x---> the length of the second wire

2(3x)=6x -----> the length of the third wire

Part a) WRITE AN *INEQUALITY* THAT MODELS THE SITUATION

we know that

The inequality that represent the situation is

x+(3x)+(6x) \leq 350

Part b) WHAT ARE THE POSSIBLE LENGTHS OF THE SHORTEST PIECE OF WIRE?

we know that

The shortest piece of wire is the first wire

so

Solve the inequality

x+(3x)+(6x) \leq 350

10x \leq 350

x \leq 35\ in

The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to 35\ inches
