The floor of a cargo truck is 22 1/2 square feet. What is the volume of the storage space in cubic feet if the truck is 7 1/5 feet high? Show, label, and explain your work.
Answer:
162 ft^3
Step-by-step explanation:
volume = area of base * height
V = 22 1/2 ft^2 * 7 1/5 ft
Change the mixed numerals into fractions.
V = 45/2 ft^2 * 36/5 ft
Multiply the fractions.
V = 45/2 * 36/5 ft^3
Switch the denominators.
V = 45/5 * 36/2 ft^3
Simplify each fraction.
V = 9 * 18 ft^3
V = 162 ft^3

what is the value of x in simplest radical form?
Answer:
25
Step-by-step explanation:
For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.
Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.
NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!
With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.
This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.
This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.
And that, my friend, is your answer. Hope this helped :)

PLZ HELP To multiply (7x+3)(7x−3),
you can use the pattern:
(a+b)(a−b)=a2−b2.
What are the values of a and b?
Enter your answers in the boxes below.
a=
b=
Answers:
a = 7xb = 3==========================================================
Explanation:
Match up (7x+3)(7x-3) with (a+b)(a-b)
We have
(7x+3) pair up with (a+b)(7x-3) pair up with (a-b)We can see that a = 7x and b = 3
Furthermore, we can say,
(a+b)(a-b) = a^2 - b^2
(7x+3)(7x-3) = (7x)^2 - (3)^2
(7x+3)(7x-3) = 49x^2 - 9
The values of a and b are 7x and 3 respectively
(7x+3) (7x−3)
Using the format
Factorisation(a + b)(a − b) = a² − b²
Therefore,
a = 7x
b = 3
Therefore,
From (a + b)(a − b) = a² − b²
(7x+3) (7x−3) = (7x)² - 3²
(7x+3) (7x−3) = 49x² - 9

90 = x + 2x
90 = 3x
90 / 3 = 20
3x / 3 = x

Solve for x if -10x + 67 = 17
A) x=4
B) x= -50
C) x=5
D) x=10
Answer:
x=5
Step-by-step explanation:
First off, you need to subtract 67 from 17 to get the variable alone.
That will leave you with -10x=-50
Then you need to divide -10 and -50,
Two negatives make a positive so
x=5

Answer:
f(1) = 4
Step-by-step explanation:
f(1) means let x=1 and find the y value at that point on the graph
At x=1 there is an open circle and a closed circle. The open circle means that the function does not have a value at that point, so we use the closed circle
f(1) = 4

write an equation of the line that passes through the point (0,3) and whose slope is 2
Answer:
y - 2x = 3
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:
y - 3 = 2(x - 0), or
y - 3 = 2x, or
y - 2x = 3
Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b: it is 3.

Anyone know how to solve this? Im losing brain cells
Answer and Step-by-step explanation:
The answer is A.
y = x + 2 and y = -2x + 4
This is because:
- The graph going from left to right matches the first equation, in which the graph has a slope of 1 and has a y-intercept at (0, 2).
- The graph going from right to left matches the second equation, in which the graph has a slope of -2 (Since it is going from right to left), and has a y-intercept at (0, 4).

A researcher takes a random sample of 2,496 drivers and finds that 1,603 put their phone in "drive mode” to not be distracted while driving. A 90% confidence interval for the proportion of drivers who use "drive mode” on their phones is (0.626, 0.658). Which statement correctly interprets the interval? The researcher can be 90% confident that 64% of all drivers will use “drive mode” while driving. There is a 90% probability that the proportion of drivers who use “drive mode” lies between 0.626 and 0.658. The researcher can be 90% confident that the interval from 0.626 to 0.658 captures the true proportion of all drivers who use “drive mode.” If this procedure is repeated many, many times, the true proportion of drivers who use “drive mode” will be captured 90% of the time.

work out the circumference of a cirlce with a diameter of 1.8m
Answer:
5.56 m
Step-by-step explanation:
Circumference = 2πr
r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:
1.8 ÷ 2 = 0.9
Circumference = 2 × π × 0.9
= 5.56 m ( in 3 significant figures )

Intercepts: independent practice Write the ordered pair describing the coordinates of each intercept. 1. X-intercept: -6 2. Y-intercept: -2.3 3. Y-intercept: 3/4
Answer:
[tex](-6, 0)[/tex]
[tex](0, -2.3)[/tex]
[tex](0,\frac{3}{4})[/tex]
Step-by-step explanation:
Solving (1). x-intercept: -6
At x intercept, [tex]y= 0[/tex]
So, the ordered pair is: [tex](-6, 0)[/tex]
Solving (2): y-intercept: -2.3
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0, -2.3)[/tex]
Solving (3): y-intercept: 3/4
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0,\frac{3}{4})[/tex]
