Step-by-step explanation:

First find the angle BAC

BAC= 180 -(90+50) ( interior angle of triangle is 180)

BAC= 180- 140

= 40 degrees

sin 40= opposite/ hypotaneus

sin 40 = 2/ hyp

0.6427 = 2/ hyp

hypotaneus = 2/ 0.6427

hypotaneus = 3.1118

AB= 3.1118

to nearest hundredth = 3.11

What is the answer to 8 and 9 please help thank you

2|x-5|<16 has several integer solutions. What are they?

First, div. both sides by 2, obtaining |x-5| < 8.

One way to solve this would be to add 5 to both sides: |x| < 13.

This inequality has several integer soltuions. One such solution is 12. Notice how |12| < 13 is true. Another solution is -12. Show that this is true.

Then the solution set is {-12, -11, -10, .............. , 11, 12}

It takes Emma 18 minutes to type and spell check 14 pages of a manuscript. Find how long it takes her to type and spell check 77

NNADVOKAT [17]

Answer:

99 minutes, or an hour and 39 minutes.

Step-by-step explanation:

It takes Emma 18 minutes to do 14 pages. That means that we can set up a proportion, where Emma uses 18 minutes to do 14 pages, which is equal to x minutes per page!

$\frac{18}{14} =\frac{x}{1}$

14x = 18

7x = 9

x = 9/7

So, each page takes 9/7 minutes for Emma to finish.

She will do 77 pages. 77 * (9/7) = 11 * 9 = 99.

So, it will take Emma 99 minutes, or an hour and 39 minutes, to type and spell check 77 pages.

Hope this helps!

Find the area of the shape below 11 ft 7 ft 10 ft 8 ft 2 ft

dimaraw [331]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

Area of whole shape = Area of greater rectangle - area of smaller rectangle

Area of greater rectangle :

$\qquad \sf \dashrightarrow \:11 \times 10$

$\qquad \sf \dashrightarrow \:110 \: \: ft {}^{2}$

Area of smaller rectangle :

$\qquad \sf \dashrightarrow \:7 \times 8$

$\qquad \sf \dashrightarrow \:56 \: \: ft {}^{2}$

Area of composite figure :

$\qquad \sf \dashrightarrow \:110 \: ft {}^{2} - 56 \: ft {}^{2}$

$\qquad \sf \dashrightarrow \:54 \: {ft}^{2}$

Given a soda can with a volume of 15 and a diameter of 2, what is the volume of a cone that fits perfectly inside the soda can?

Naddika [18.5K]

Check the picture below.

so, a cone, that fits inside the cylinder, will have the same height "h" and radius "r". Thus

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\qquad \boxed{\pi r^2 h}=15
\\\\\\
\textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\implies V=\cfrac{\boxed{15}}{3}$
