B.Longitudinal section
C.Cylindrical Section
D.Middle section

Answers

Answer 1
Answer:

Answer:

cross section

Step-by-step explanation:

The area formed by a plane cutting through a solid perpendicular to its axis is a cross section.

A cross section area is the area obtained from a three dimensional object like sphere when it is sliced at any axis perpendicular at a point. For example cross section of a cylinder sliced parallel to its base is circle.

Answers

The incenter is equidistant from all three triangle sides.
So, PJ = PK = PL.
PJ = 4x -8
PL = x + 7

Therefore,
4x -8 = x + 7
3x = 15
x = 5
So, PJ = 12
PL = 12 and
PK = 12

Money off coupons have been circulated to 300 households. Only 2/5 of these were redeemed (used) in the local supermarket to get a free shampoo. What fraction of the coupons were unused ?

Answers

if 2/5 were used wouldn't it make sense that 3/5 were unused

Answer:

150

Step-by-step explanation:

So, 300 divided by 2/5 = 750.

When you simplify:

750 - 300 = 450 (NOT DONE YET!)

450 - 300 = 150

150 is the most simplified answer.\

The sum of 555 consecutive odd numbers is 135135135.

Answers

I'm guessing you mean to say that sum of 5 consecutive odd numbers is 135. In that case, let x be the first number. Then

x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135

5x + 20 = 135

5x = 115

x = 23

So the numbers are 23, 25, 27, 29, and 31.

If you really did mean 555 consecutive odd numbers summing to 135,135,135, the process is the same, but you would find a non-integer solution so that wouldn't be possible.

Answer:

The answer is 25

If a gain of 5 yards is shown by 5, what does -5 mean?

Answers

Step-by-step explanation:

Think of all possible numbers walking back and forth, positive means walking forward, negative means walking backwards. You start at zero, so 5 represents walking 5 yards forward. This would mean that negative 5 means walking backwards, it would still be five yards. Since 5 is a gain of 5 yards, -5 would mean a loss of 5 yards.

Help me please it’s on spheres thankyou

Answers

Answer:

452.3893421 cm^2

452.4 (to one decimal place)

Step-by-step explanation:

Radius (r) - 6cm

The surface area of sphere = 4pi r^2

therefore:

4 * pi * 6^2

4 * pi * 36

144 * pi

452.3893421 cm^2

452.4 (to one decimal place)

Answer:

Surface area = 452,4

Step-by-step explanation:

radius = 6 cm

Surface area = 4πr²

Surface area = 4(3.1416)(6)²

Surface area = 12.5664 (36)

Surface area = 452, 3904

Surface area = 452,4
