Which ballon was father from the town at the beginning, and which traveled more quickly.

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour, and then walked

RUDIKE [14]

The system of equations that represents this situation are:

q + p = 2

4q + 5p = 8

Solution:

Let q be the number of hours it took Courtney to walk from her house to the beach

Let p be the number of hours it took her to walk from the beach to the park

The entire walk took 2 hours

Therefore,

q + p = 2 ------- eqn 1

The total distance Courtney walked was 8 kilometers

Total distance = 8 km

Courtney walked from her house to the beach at a constant speed of 4 kilometers per hour

Then walked from the beach to the park at a constant speed of 5 kilometers per hour

Distance is given as:

$distance = speed \times time$

From her house to the beach:

$distance = 4 \times q = 4q$

From the beach to the park:

$distance = 5 \times p = 5p$

We know that,

Total distance = 8 km

Therefore,

4q + 5p = 8 ------ eqn 2

Thus the system of equations that represents this situation are:

q + p = 2

4q + 5p = 8

What is m∠HLK? thanks

Katen [24]

The answer is 80°.

If there is a line segment in a triangle which cuts two sides in half or if there is a line segment between two midpoints of a triangle's sides, that line segment must be parallel to the remaining side.

In this case, point L is the midpoint of FH, and point K is the midpoint of HG. So, LK is parallel to FG.

When a line cuts two parallel lines, there are angle pairs which are equal. In the problem above, the line segment FH cuts KL and GF.

The angles KLH and GFH are what we called "Corresponding Angles" and they are equal.

So if HFG is 80°, HLK must be equal to 80°

Tyler filled up his bathtub, took a bath, and then drained the tub. The function

TiliK225 [7]

Answer:

B(0) = 0 depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0

B(1) represents the function one minutes after filling began.

B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.

Step-by-step explanation:

The function gives depth of water in inches 7 minutes after filling began

A.) B(0)=0

The statement B(0) = 0 means the depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0

B.) B(1)

B(1) represents the function one minutes after filling began.

C.B(9)=11

B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.

You want to buy a trampoline. You found one online that has a circumference of 6.28 yards. What is the area?

gizmo_the_mogwai [7]

The area of the trampoline is mathematically given as

a = 3.14

Question Parameters:

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference is mathematically given as

C = 2*pi*r

Thererfore

6.28 = 2*3.14*r

r = (6.28)/(6.28)

r = 1

In conclusion, where radius is

$a= pi*r^2$

a = 3.14*1^2

a = 3.14
