Answer:

  3) x = 9

  4) x = 3

Step-by-step explanation:

3) The two short segments are indicated as having a sum equal to the long segment.

  (x +2) +(-5 +x) = 15

  2x = 18 . . . . . . . . . . . . add 3

  x = 9 . . . . . . . . . divide by 2

(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

__

4) Same deal.

  3x +3 = 4x

  3 = x . . . . . . . . subtract 3x

(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)

Answer:

96

Step-by-step explanation:

The ratio of the measure of sides of a triangle are 8:15:17

The perimeter is 480

8x + 15x + 17x= 480

40x= 480

x = 480/40

x = 12

Therefore the measure of the shortest side of the triangle can be calculated as follows

8x

8×12

= 96

Answer:1,2,3,5

Step-by-step explanation:

Answer:

[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]

Step-by-step explanation:

First find the midpoint of the segment  from (2, -6) to (-4, -16)

((2 - 4)/2, (-6 - 16)/2)

(-2/2, -22/2)

(-1, -11) is the midpoint and is the center of the circle

Now find the distance between the 2 given points and divide by 2 to get the radius of the circle

d = [tex]\sqrt{(2 + 4)^{2} + (-6 + 16)^{2} }[/tex]

  = [tex]\sqrt{6^{2} + 10^{2} }[/tex]

  = [tex]\sqrt{36 + 100}[/tex]

  = [tex]\sqrt{136}[/tex]

r = [tex]\sqrt{136}[/tex]/2

[tex]r^{2}[/tex] = 136/4 = 34

Equation of circle with center at (-1, -11) and radius = [tex]\sqrt{34}[/tex] is

[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]

Answer:

A: 4:3:5

Step-by-step explanation:

Al ate 1/3 of the pizza. 1/3 can also be written as 4/12. Barb ate 1/4 of the pizza. 1/4 can also be written as 3/12. 4/12 plus 3/12 is equal to 7/12. One whole would be 12/12, so to get the remaining amount of pizza, do 12/12-7/12, to give you 5/12. 4:3:5. We needed to make all of the fractions have a common denominator in order to solve this particular problem.

The slope is a zero slope. This means that the line is a straight, horizontal line.

Step-by-step explanation:

Use the slope formula.

Step-by-step explanation:

Area of triangle (A1)

= 1/2 * b *h

= 1/2 * 1 * 1

= 1/2 ft

Area of rectangle (A2)

= L * b

= 3 *1

= 3 ft

Total area

= A1 + A2

= 1/2 + 3

= (1 + 6 ) / 2

= 7/2 ft²

= 3.5 ft²

Answer:

4

Step-by-step explanation:

cos(-π) = -1 [in radians]

3-(-1) = 4

There are many ways to answer this but, I'll try to explain it.

You can see that you are computing a limit when some n approaches negative PI. You get to substitute negative PI instead of n and compute cos(-pi) which is -1.

Then compute f(x) - (-1) = 3 - (-1) = 4 which is a result.

The way you can imagine cos(-pi) or cos(-90deg) is by dragging point in a unit circle beneath x-axis and to the bottom y-axis (-90 angle), the y coordinate tells you the cosine value at (-90) and because you have dragged the point on the unit down to y-axis the value is -1.

Hope this helps.

Step-by-step explanation:

Answer:

2400 foot pounds

Step-by-step explanation:

The amount of work done by the four men is  1200 ft-lbs. so option B is correct.

The muscular work done by each man is equal to the weight of the boxes carried multiplied by the vertical distance moved.

The weight of each box is 5 pounds, and each man carries 20 boxes, so the total weight carried by each man is:

20 boxes x 5 pounds/box = 100 pounds

The vertical distance moved is the height of the ramp, which is 30 feet.

Therefore, the muscular work done by each man is:

Muscular work = weight x vertical distance

Muscular work = 100 pounds * 30 feet

Muscular work = 3000 ft-lbs

Since there are four men carrying boxes, the total muscular work done is:

Total muscular work = 4 * 3000 ft-lbs = 12000 ft-lbs

Therefore, the answer is B. 1200 ft-lbs.
