Answer:

128

Step-by-step explanation:

A triangle's angles must add up to 180 degrees, so 180 = 40 + 12 + x which is the same as 180 - 40 - 12 = x

x = 128

145 is what percent of 620
Oksanka [162]

Hello There!

145 is 23.39% of 620

<u><em>HOW TO SOLVE</em></u>

<u><em></em></u>

<u><em>Equation: Y = P% * X</em></u>

<u><em>We need to solve our equation for "P"</em></u>

<u><em>P% = Y/X</em></u>

<u><em>P% = 145/620</em></u>

<u><em>p = 0.2339</em></u>

<u><em></em></u>

<u><em></em></u>

<u><em>Convert decimal to percent:</em></u>

<u><em>Percent = 0.2339 * 100 = 23.39%</em></u>

The top of a storage container is a hemisphere with a diameter of 28 feet. What is the volume of the storage container? Round yo
creativ13 [48]

Answer:

5749.3 cubic feet

Step-by-step explanation:

The volume of the  storage container would be defined by the volume of the shape; a hemisphere

The volume V of  a hemisphere is given as

V = 2/3 π r^3

where r is the radius of the hemisphere

Given that the diameter is 28 feet, the radius = 14 feet

hence the volume

= 2/3 * π * 14^3

= 5749.333333

To the nearest tenth

= 5749.3 cubic feet

Find the value of x<br><br>d:6​
Phantasy [73]

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

Let's solve for x ~

\qquad \sf  \dashrightarrow \: 5x = 3x + 12

[ by vertical opposite angle pair ]

\qquad \sf  \dashrightarrow \: 5x - 3x = 12

\qquad \sf  \dashrightarrow \: 2x = 12

\qquad \sf  \dashrightarrow \: x = 12 \div 2

\qquad \sf  \dashrightarrow \: x = 6

Therefore, the correct choice is D. 6

I need the description of how to draw a parallel line and a perpendicular line.
EleoNora [17]
How to Draw Parallel Lines:
1. Draw a straight line any length

2. Draw another straight line any length

(note : ensure the lines will never intersect)

They shall never horizontally or vertically.

How to Draw Perpendicular Lines:
1. Draw a straight line vertically

2. Draw a straight line horizontally

(note : length does not necessarily matter)

The two lines must cross at right angles to each other!!

With the parallel line instructions, simply just draw lines but, when given the slopes of two lines, you must get graphing paper or make your own, and graph it by plotting points and then getting a ruler and tracing it.

With the perpendicular lines it helps with showing a relation between situations along with given slopes. They shall intersect always and meet at a 90° angle. Use the equations and plot them then take a ruler and trace them and notice the intersection. Solve it yourself and see that the intersection and the answers you got are the same.
