What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
<------------6m----------------->
Ball ____________________
Ball_________
<------3m------>
Distance traveled by the ball.
= 6 m + 3m
= 9 m
Displacement is the shortest distance traveled by the ball.
= 6 - 3
= 3m
Thus,
Displacement is 3m.

In 1978, the amount of earnings required to earn one Social Security credit was $250. Thirty years later, in 2008, this amount was $1,150. What was the percent increase in the amount required to earn a credit, over this 30-year span? Use a percent sign .
Answer:
the percentage increase is 360%
Step-by-step explanation:
The computation of the increase in percentage is shown below;
Given that
SOcial security credit as on 1978 is $250
And, the social security tax as on 2008 is $1,150
Now based on the above information
The percentage increase is
= ($1,150 - $250) ÷ ($250)
= 360%
Hence, the percentage increase is 360%
Water flows into a tank according to the rate F(t) = t+6/1+t, and at the same time empties out at the rate E(t) = ln(t+2)/t+1, with both F(t) and E(t) measured in gallons per minute. How much water, to the nearest gallon, is in the tank at time t = 10 minutes. You must show your setup but can use your calculator for all evaluations.
Answer:
12.29minutes
Step-by-step explanation:
The net flow rate = flow in - flow out = F(t) - E(t) = t+6/1+t - ln(t+2)/t+1 = [(t + 6) - ln(t+2)]/(t+1)
So, the amount of water present in the tank at time, t is A = net flow rate × time = [(t + 6) - ln(t+2)]/(t+1) × t = t[(t + 6) - ln(t+2)]/(t+1)
At t = 10 minutes,
A = t[(t + 6) - ln(t+2)]/(t+1)
A = 10[(10 + 6) - ln(10+2)]/(10+1)
A = 10[16 - ln12]/11
A = 10[16 - 2.485]/11
A = 10[13.515]/11
A = 135.15/11
A = 12.29 minutes
Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the j$ fare among the 3 of them. Angela also paid a $5, tip. How much did Angela pay in total?
Answer:
[tex]$\frac{j}{3}+5$[/tex]
Step-by-step explanation:
It is given Angela shared a cab with her 2 friends.
Total number of people = 3
Total fare = j $
Tip paid by Angela = $ 5
The total fare was equally divided by the 3 friends.
So, fare paid by angle = [tex]$\frac{j}{3}$[/tex]
Total money paid by Angela is = fare + tip

Sharon is buying a circular rug for her room. The diameter of the rug is 8 feet which measurement is closest to the area of the rug in square feet
Answer:
50.24 feet²
Step-by-step explanation:
Given that:
Diameter of circular rug = 8 feets
To obtain the area of the circular rug, we use the formula for the Area of a circle = πr²
A = πr²
r = Radius of circle = diameter / 2 = 8 /2 = 4 feets
Area of circular rug = π * 4²
Area of circular rug = 3.14 * 16 = 50.24 feet²

Step-by-step explanation:
Reference angle = x°
Opposite = 17
Hypotenuse = 19
Apply the trigonometric function, SOH:

Substitute
[tex] sin(x) = \frac{17}{19} [/tex]
[tex] x = sin^{-1}(\frac{17}{19}) [/tex]
x = 63.474648° ≈ 63.5° (nearest tenth)

The measure of angle ∠1 and angle ∠3 will be 85° and 55°, respectively.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
In the figure, ∠2 = 55° and ∠4 = 85°.
Angle ∠1 and angle ∠4 are vertically opposite angles. Then we have
∠1 = ∠4
∠1 = 85°
Angle ∠2 and angle ∠3 are vertically opposite angles. Then we have
∠3 = ∠2
∠3 = 55°
The measure of angle ∠1 and angle ∠3 will be 85° and 55°, respectively.
