Answer:
420
Step-by-step explanation:
V = whl is the volume of a rectangular prism. w*h is the area, so V is area times height.
This gives us: V = 30 * 14 = 420.
Can you reflect an angle over the line y = -x? Explain.
O No, there is not a way to map the vertex of the preimage angle to the vertex of the image angle.
Yes, only angles can be reflected over diagonal lines.
O No, you cannot reflect angles over diagonal lines.
O Yes, you can reflect angles, or any object, in the coordinate plane over any line in the plane.
Answer: Yes, only angles can be reflected over diagonal lines.

7/16 = ___% ai need it step by step
Answer:
43.75%
Step-by-step explanation:
Step 1: Divide 7 by 16 to get the number as a decimal. 7 / 16 = 0.44
Step 2: Multiply 0.44 by 100. 0.44 times 100 = 43.75. That's all there is to it!
7.7 cm
A company is designing a new cylindrical water
bottle. The volume of the bottle will be 115 cm3.
The height of the water bottle is 7.7 cm. What is
the radius of the water bottle? Use 3.14 for r.
Step-by-step explanation:
I guess the 3.14 is to be used for pi (and not r, which is what we need to find out).
the volume of a cylinder is ground area × height.
the ground area is the area of a circle, which is pi×r².
so, we have
pi×r²×height = 115 cm³
3.14×r²×7.7 = 115 cm³
3.14×r² = 14.93506494...
r² = 4.756390107...
r = 2.18091497... cm

The population of Atlanta Georgia in the year 2000 was 417,000 people. If the population increases at a rate of 1.2% each year, find the approximate population of Atlanta in
2020.
Step-by-step explanation:
geometric sequence :
a0 = 417,000
a1 = a0 × 1.012 (that is adding 1.2% for 2001)
a2 = a1 × 1.012 = a0 × 1.012²
an = a0 × 1.012^n
a20 (for the year 2020 after starting in 2000) =
= a0 × 1.012²⁰ = 417,000 × 1.012²⁰ = 529,354.1291...
if we need to round that to a full number, we get
≈ 529,534
our round it to full thousands
≈ 530,000

Dr. Bayer measured the masses of newborn twins. Baby A weighs 2.8 kilograms. Baby B weighs 2,950 grams. What is the difference between the masses of these newborn twins in grams? OPTIONS
Convert 2.8 kilograms into 2800 grams.
Baby A weighs 2800 grams, baby B weighs 2950 grams -> The difference between the masses = 2950 - 2800 = 150 grams.

By analyzing when the piecewise function increases and when it decreases, we can conclude that the true statement is:
"The function is increasing over the interval −8≤x≤−2."
Which statements are true?We know that our function is made of straight lines that connect:
Point (-8, 3) with (-2, 8) {This is an increasing line}Point (-2, 8) with (2, 8) {This is a horizontal line}Point (3, 0), and (7, -7) {This is a decreasing line}(to see if it increases or decreases, compare the y-value of the second and first point.

Step-by-step explanation:
You take the number of each x then times by the number on the bottom so in this case, you have 3 15s that would be 45. for the 16s you have 5 so you do this math and you end up with 80 and keep going until you did all of them then add them up and that's your answer.
Let's analyze the data
Three players got 15 strikeoutsFive players got 16 strikeoutsTwo players got 17 strikeoutsTwo players got 18 strikeoutsNow lets solve:
Total number of strikeouts = 3 * 15 + 5 * 16 + 2*17 + 2*18

In the diagram, secant AP intersects the circle at points A and B, and secant CP intersects the circle at points C and D. The lines intersect outside the circle at point P.
What is the length of AP?
(There are no answer options you must enter the correct value)
Answer AP might be 12
Step-by-step explanation:
The length of AP when secant AP intersects the circle at points A and B, and secant CP intersects the circle at points C and D. is 12 units.
The length of AP can be found using the following steps:
Draw a radius from the center of the circle to point P.
Let the radius intersect secant AP at point E.
Since AP and PE are secant segments, they share a common external tangent at point P.
Therefore, the two triangles, APE and BPF, are similar triangles.
The ratio of corresponding sides in similar triangles is equal, so:
AP/PB = PE/PF
We know that PB = 5 and PF = 20, so:
AP/5 = PE/20
Solving for AP, we get:
AP = 5 * 20/5 = 20
The diagram shows the two similar triangles, APE and BPF. The two triangles are similar because they share a common external tangent at point P. The ratio of corresponding sides in similar triangles is equal, so we can use the ratio of AP to PB to find the length of AP.
