Answer:

157 inches squared

Step-by-step explanation:

Divide the figure into smaller figures (see image for one way):

Then, find the area of each figure. In my example:

= (4x5)+(5x12)+(11x7)

= 20+60+77

= 80+77

= 157 inches squared

On the following equation: y = -7/3 + 4. Which one is the slope? *
Alex

Answer:

If you look at the slope-intercept form equation: y = mx + b

y is the output, m is the slope, and b is the y-intercept. To find the slope, you need to look at mx for your equation.

Since it is y=-\frac{7}{3}x +4 you need to look at the number before the x, which in this case will be -7/3

So your slope will be m = -7/3

Please explain as well, solve the trigonometric equation
aliina [53]

Given:

The trigonometric equation is:

\tan x\sin x=\tan x\cos x

To find:

The solutions for the given equation over 0^\circ.

Solution:

We have,

\tan x\sin x=\tan x\cos x

It can be written as

\tan x\sin x-\tan x\cos x=0

\tan x(\sin x-\cos x)=0

\tan x=0 and (\sin x-\cos x)=0

The solutions over 0^\circ are:

x=90^\circ,180^\circ and \sin x=\cos x

x=90^\circ,180^\circ and x=45^\circ, 225^\circ

Therefore, the correct option is D.

Find the volume of a sphere, to the nearest tenth, that has a radius of 7cm
Natali [406]

The formula of a volume of a sphere with radius R:

V=\dfrac{4}{3}\pi R^3

We have R = 7cm. Substitute:

V=\dfrac{4}{3}\pi\cdot7^3=\dfrac{4}{3}\pi\cdot343=\dfrac{1372\pi}{3}\ cm^3

\dfrac{1372\pi}{3}\approx1436.0\ cm^3

<h3>Answer: V = 1436.0 cm³</h3>

A bag contains four red marbles, three blue marbles, and three yellow marbles. You randomly pick three marbles without replaceme
Dennis_Churaev [7]
4 red, 3 blue, 3 yellow ....total = 10

P(red) = 4/10 reduces to 2/5
without replacement
P(blue) = 3/9 reduces to 1/3
without replacement
P(red) = 3/8

P( all this happens) = 2/5 * 1/3 * 3/8 = 6 / 120 reduces to 1/20 <=
