Answers

Answer: 840

Step-by-step explanation: 50% is half. All I did was add 420  two time since 420 is half of what this person has to spend.

Answer:

the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.

0.50 times 420= 210

210 is the correct answer and have a great day.

[tex]\boxed{\sf volume = 320 \ ft^3}[/tex]

Explanation:

Volume of triangular prism = 1/2 × Base × Height × Length

Identify the following:

Base: 6 2/3 ftHeight: 8 ftLength: 12 ft

Find Volume:

1/2 × 6 2/3 × 8 × 121/2 × 640320 ft³
Question :- Volume of the triangular prism.

Given in the figure:- height = 8 ftlength = 12ft width = 6⅔ ft

Formula:-Volume = area of triangle (2D ) × length Area of triangle = ½ × height× width

Explanation:-

[tex]Area \: of \: triangle = ½ × height× width \\ area = \frac{1}{2} \times 8 \times \frac{20}{3} \\ area = \frac{{ \cancel8} {}^{ \: \: 4} }{ \cancel2} \times \frac{20}{3} \\ area = \frac{80}{3} {ft}^{2} [/tex]

Now for volume :-

Volume = area of triangle (2D ) × length

[tex]volume = area \times length \\ vol = \frac{80}{3} \times 12 \\ vol = \frac{80}{ \cancel3} \times { \cancel{12}} {}^{ \: \: 4} \\ volume = 320 {ft}^{3} [/tex]

Answer:- volume = 320 ft³

Vivek is making a perpendicular segment in the middle of segment JR.

First, he drew an arc centered at J.
Then, he used the same radius to draw an arc centered at R.
Next, he found the points where the arcs intersected.

What MUST be true?

Line J R. Point P is above the line and point N is below the line. Arcs centered at J and R go through points P and N.
CLEAR CHECK

P is the same distance from N as J is from R.


PN is equal to JR.


Any point on PN will be equidistant from J and R.

Answers

Answer:

x = 3

y = 1

Step-by-step explanation:

So to solve this by addition we have to add both x's, y's and the numbers on the other side of the equal sign:

x + y = 4

x - y = 2

Both y's will cancel out because we are subtracting y from y

Adding 4 +2 = 6

2x = 6          (adding both x gets 2x)

x = 3

Now that we found x we can find y by plugging it into either equation:

3 + y = 4

y = 1

We can check these in both equations:

3 + 1 = 4        4 = 4

3 - 1 = 2        2 = 2

These answers are then proven correct!

I hope this helps! Good luck!

Answers

Answer:

59°

Step-by-step explanation:

The total of all the angles in a triangle should amount to 180°. So:

64° + 57° = 121°

180° - 121° = 59°

Answer: 121

First you need to find the angle of the third unknown space within the triangle. To do this, add 57 and 64. The answer to this is 121. Then, subtract 121 from 180. The answer to this is 59. Now that you know the unknown angle within the triangle, subtract 59 from 180 to find the measure of angle 1.
