4. An isosceles triangle has sides that measure 7cm and 15cm. Find the third side of the
Advocard [28]

Answer:

Third side is 15cm. Perimeter is 37cm.

Step-by-step explanation:

In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.

So if the third side is 7cm

7+7=14cm which is less than 15 cm.

hence third side is 15 cm as

15+15=30cm which is greater than 7cm

15+7=22cm which is greater than 12cm

then

perimeter=15+7+15=37cm

The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth o
ICE Princess25 [194]
Given:
radius : 3.5 ft
height : 14 ft

Surface Area of a cylinder = 2πrh + 2πr²
S.A. = 2 * 3.14 * 3.5ft * 14ft + 2 * 3.14 * (3.5ft)²
S.A. = 307.72ft² + 2 * 3.14 12.25ft²
S.A. = 307.72ft² + 76.93ft²
S.A. = 384.65 ft²  

Volume of a cylinder = πr²h
V = 3.14 * (3.5ft)² * 14ft
V = 3.14 * 12.25ft² * 14ft
V = 538.51 ft³

Which of the g-values satisfy the following inequality?
sleet_krkn [62]

Answer:

B: g=5

C: g=6

Step-by-step explanation:

Given

7 \ge 12 - g

Required

All possible values of g

We have:

7 \ge 12 - g

Collect like terms

7 - 12\ge  - g

-5\ge  - g

Divide both sides by -1 [The inequality changes because of negative division]

5\le  g

Swap both terms

g \ge 5

This implies that g is greater than of equal to 5

i.e.

g= \{5,6,7.....\}

Hence:

(b) and (c) are correct
