Answer:

Reflection over the x-axis

Step-by-step explanation:

To get from Triangle A to Triangle B, Triangle A must be reflected over the x-axis. On Triangle A, the left-most point is at (1, -2). The corresponding point on Triangle B is at (1, 2). The rule for reflecting over the x-axis is (x, y) -> (x, -y). So, (1, -2) -> (1, 2).

I hope this helps :))

The picture is kind of grainy but it looks like:
4u = 56

Add 4's to both sides:
4u/4 = 56/4

cross out both 4's on left side and divide on the right:
u = 14

Find the volume of a sphere with a great circle area of 201.06 square inches

Vikentia [17]

Assuming you meant a "circular cross-section" of 201.06 in².

so, we know if we cut the sphere like a cantaloupe, in half, the circular inner-part of the cantaloupe will have an area of 201.6 in².

keeping in mind that, the radius of that circular section, is the same radius of the sphere, what is it anyway?

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
-----\\
A=201.06
\end{cases}\implies 201.06=\pi r^2
\\\\\\
\cfrac{201.06}{\pi }=r^2\implies \sqrt{\cfrac{201.06}{\pi }}=r\\\\
-------------------------------$

$\bf \textit{volume of a sphere}\\\\
V=\cfrac{4\pi r^3}{3}\qquad \qquad \implies V=\cfrac{4\pi \left( \sqrt{\frac{201.06}{\pi }} \right)^3}{3}\implies V=\cfrac{4\pi \left( \frac{\sqrt{201.06^3}}{\sqrt{\pi ^3}} \right)}{3}
\\\\\\
V=\cfrac{4\pi \cdot \frac{\sqrt{201.06^3}}{\pi \sqrt{\pi }}}{3}\implies V=\cfrac{\frac{4\sqrt{201.06^3}}{\sqrt{\pi }}}{3}\implies V=\cfrac{4\sqrt{201.06^3}}{3\sqrt{\pi }}$

James, Priya, and Siobhan work in a grocery store. James makes $9.00 per hour. Priya makes 20% more than James, and Siobhan make

s344n2d4d5 [400]

Answer:

Siobhan makes $9.18 per hour.

Step-by-step explanation:

9*20% is 1.8 so add that to 9 to get 10.80 then times 10.80 by 15% to get 1.62 so you subtract 1.62 from 10.80 to get $9.18

A fruit company ships boxes of apples and pears in a crate that measures

vfiekz [6]

Answer:

none of the above

Step-by-step explanation:

The crate has a volume of ...

V = LWH = (15 in)(18 in)(24 in) = 6480 in³

The apple box has a volume of ...

V = LWH = (15 in)(15 in)(10 in) = 2250 in³

The pear box has a volume of ...

V = LWH = (12 in)(12 in)(12 in) = 1728 in³

Together, one box of each fruit takes up a volume of ...

(apple box) + (pear box) = (2250 in³) + (1728 in³) = 3978 in³

Then the part of the crate not filled has a volume of ...

6480 in³ -3978 in³ = 2502 in³ . . . . not among the answer choices

What is the frequency heard by a person driving at 15 m/s toward a blowing factory whistle (800. Hz) if the speed of sound is 34

bija089 [108]

Answer:

Answer:

835.29 Hz

Explanation:

When moving towards the source of sound, frequency will be given by

f*=f(vd+v)/v

Where f is the freqiency of the source, vd is the driving speed, v is the speed of sound in air, f* is the inkown frequency when moving forward.

Substituting 800 Hz for f, 340 m/s for v and 15 m/s for vd then

f*=800(15+340)/340=835.29411764704 Hz

Rounded off, the frequency is approximately 835.29 Hz
