Answer:
3/5 hour
4 1/3 miles per hour
6 1/15 miles per hour
Step-by-step explanation:
Given that the object is travelling at a steady speed of 8 2/3 miles per hour and covers 5 1/5 miles
Recall that distance = speed * time
hence
5 1/5 miles = 8 2/3 miles per hour * time t
26/5 = 26/3 * t
Multiply both sides by 3/26
26/5 * 3/26 = t
t = 3/5 hour
If the object reduces its speed by 1/2, the new speed
= 1/2 * 8 2/3 miles per hour
= 1/2 * 26/3
= 13/3 miles per hour
= 4 1/3 miles per hour
If the object reduces its speed by 30%, the new speed
= 8 2/3 miles per hour - 30% * 8 2/3 miles per hour
= 0.7 * 8 2/3 miles per hour
= 7/10 * 26/3
= 91/15
= 6 1/15 miles per hour

A gallon of water weighs 8.34 pounds. The Sanchez family has a round, 15 foot diameter, above- ground pool. How much weight is added to the pool when it is filled with 5,305 gallons of water?
==========================================================
Work Shown:
1 gallon = 8.34 pounds
5305*(1 gallon) = 5305*(8.34 pounds)
5305 gallons = 44,243.7 pounds
Note: the information about the 15 foot diameter is not used at all.
The weight of the water that needs to be added to the pool when it is filled with 5,305 gallons of water is 44,243.7 pounds option (B) is correct.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
It is given that:
A gallon of water weighs 8.34 pounds. The Sanchez family has a round, 15-foot diameter, above-ground pool.
Let x be the weight of the water that needs to be added to the pool when it is filled with 5,305 gallons of water.
As we know,
1 gallon = 8.34 pounds
5305×(1 gallon) = 5305×(8.34 pounds)
5305 gallons = 44,243.7 pounds
Thus, the weight of the water that needs to be added to the pool when it is filled with 5,305 gallons of water is 44,243.7 pounds option (B) is correct.

How many solutions are shown by the graph of the quadratic function? A zero B one C two D three
A solution to a quadratic is the same as the root or x intercept (when talking about real numbers). The graph shows that we have exactly one x intercept, which is where the parabola touches the x axis. So we have one root.

Answer:
-4
Step-by-step explanation:
In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).
Here, the coefficient of x is -4.
The slope is -4.
_____
Additional comment
Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...
y = kx . . . . . with no added constant
"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):
y = mx + b

gjj h 7/4 to the third power Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

A teenager who is 5 feet tall throws an object into the air. The quadratic function LaTeX: f\left(x\right)=-16x^2+64x+5f ( x ) = − 16 x 2 + 64 x + 5 is where f(x) is the height of the object in feet and x is the time in seconds. When will the ball be 10 feet in the air?
Answer:
At approximately x = 0.08 and x = 3.92.
Step-by-step explanation:
The height of the ball is modeled by the function:
[tex]f(x)=-16x^2+64x+5[/tex]
Where f(x) is the height after x seconds.
We want to determine the time(s) when the ball is 10 feet in the air.
Therefore, we will set the function equal to 10 and solve for x:
[tex]10=-16x^2+64x+5[/tex]
Subtracting 10 from both sides:
[tex]-16x^2+64x-5=0[/tex]
For simplicity, divide both sides by -1:
[tex]16x^2-64x+5=0[/tex]
We will use the quadratic formula. In this case a = 16, b = -64, and c = 5. Therefore:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Substitute:
[tex]\displaystyle x=\frac{-(-64)\pm\sqrt{(-64)^2-4(16)(5)}}{2(16)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{64\pm\sqrt{3776}}{32}[/tex]
Simplify the square root:
[tex]\sqrt{3776}=\sqrt{64\cdot 59}=8\sqrt{59}[/tex]
Therefore:
[tex]\displaystyle x=\frac{64\pm8\sqrt{59}}{32}[/tex]
Simplify:
[tex]\displaystyle x=\frac{8\pm\sqrt{59}}{4}[/tex]
Approximate:
[tex]\displaystyle x=\frac{8+\sqrt{59}}{4}\approx 3.92\text{ and } x=\frac{8-\sqrt{59}}{4}\approx0.08[/tex]
Therefore, the ball will reach a height of 10 feet at approximately x = 0.08 and x = 3.92.

Answer:
graph needs a solid dot at 13(c) ... at least 130 miles. ... at least 13 weeks.Step-by-step explanation:
The ≥ symbol means "greater than or equal to". In English, it is equivalent to "at least". On a graph, the boundary dot is drawn as solid to indicate the value represented by the dot is part of the solution.
The inequality is recognizable as the sum of miles added each week (6x) and the number of miles already completed (52). That is said to be greater than or equal to 130, so we presume the road crew's goal is "at least 130 miles."
The solution to the inequality is graphed as x ≥ 13, so we presume the time required to meet the goal will be "at least 13 weeks."
These statements match the 3rd choice.
