The length of a jogging trail is 3528 m. A jogger wants to complete the trail within 30 min. How many meters must the jogger travel each minute?
Step-by-step explanation:
We have to find the distance the jogger must travel each minute. The distance covered in one minute is:
d= 3528/1800= 1.96 m
Therefore, the distance covered in one minute, or 60 seconds is:
dt= 1.96 × 60 = 117.6 m
The solution needed is, dt=588/5 = 117 (3/5) m

A line intersects the points (0,-4) and (1,2). What is the slope-intercept equation for this line
Answer:
y = -2x
Step-by-step explanation:
First you can find the difference between the two points to find the slope.
0, 4
- 1, 2
-1, 2
Now divide: y/x = 2/-1 = -2
Slope = -2
Formula: y=mx+b
Plug in the points for the variables.
2 = -2(1) + b
2 = -2 + b
Subtract 2 from both sides to get 0 = b so this line is proportional.
Hope that helps and have a great day!

when we divide both sides inequality by a negative number, we should reverse
the symbol of the inequality
A True
B) False
Answer:
True
Step-by-step explanation:
When dividing both sides by a negative number, you reverse the inequality sign.
Answer:
(A) True!
Step-by-step explanation:
Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.

Mr. Smith is draining his pool to have it cleaned. At 8:00 A.M., it had 2000 gallons of water and at 11:00 A.M. it had 500 gallons left to drain. What is the rate of change in the amount of water in the pool?
Answer:
500 gallons per hour
Step-by-step explanation:
rate =2000-500 gallons/ 3hours
=1500 gallons/3 hours
=500gallons per hor
Using mathematical operations, we know that the rate of change is 500 gallons of water per hour.
What are mathematical operations?The rules that specify the order in which we should solve an expression involving many operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (from left to right). An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.So, the rate of change:
Hours passed is 3. (11 - 8 = 3)The water decreased after 3 hours is 1500. (2000 - 500 = 1500)Now, calculate as follows:
Rate of change = 2000 - 500/3Rate of change = 1500/3Rate of change = 500 per hourTherefore, using mathematical operations, we know that the rate of change is 500 gallons of water per hour.

The width of a piece of paper is 8.5in the length is 11in and the thickness is 0.0037inches there are 2700sheets sitting in a cabinet by the copy machine what is the volume of occupied by the paper.
Answer:
934.2 in³
Step-by-step explanation:
The following data were obtained from the question:
Width (W) = 8.5 in
Length (L) = 11 in
Thickness (T) = 0.0037 in
Number of paper = 2700 sheets
Volume occupied by the 2700 sheets of paper =?
Next, we shall determine the volume of 1 sheet of paper. This can be obtained as follow:
Width (W) = 8.5 in
Length (L) = 11 in
Thickness (T) = 0.0037 in
Volume (V) =?
Volume = Length × Width × Thickness
Volume = 11 × 8.5 × 0.0037
Volume = 0.346 in³
Thus, the volume of 1 sheet of paper is 0.346 in³
Finally, we shall determine the volume occupied by the 2700 sheets of paper as follow:
Volume of 1 sheet of paper = 0.346 in³
Volume of 2700 sheets of paper =?
1 sheet of paper occupied 0.346 in³.
Therefore, 2700 sheets of paper will occupy = 0.346 × 2700 = 934.2 in³
Thus, the volume occupied by the 2700 sheets of paper is 934.2 in³.
What is the slope-intercept form of the equation of the line through the given point and slope?
through: (2,-2), slope = -3
Answer:
b = 4
Step-by-step explanation:
Remember y = mx+b (m = slope, b = y intercept.)
We have the slope, so, no need to solve for that.
To find the y intercept, plug in the ordered pairs to y=mx+b
-2=-3(2)+b
-2=-6+b multiply like terms
4 = b Add 6 on both sides
b = 4.

if the area of the right angle to measure 308 square meters and solve an equation to find the value of y
Answer:
y = 14
Step-by-step explanation:
Area of rectangle = 308 m²
Length = (6y - 7) m
Width = 4 m
Area of rectangle = length × width
Plug in the values
308 = (6y - 7) × 4
308 = 6y×4 - 7×4
308 = 24y - 28
Add 28 to both sides
308 + 28 = 24y
336 = 24y
Divide both sides by 24
14 = y
y = 14
