Simplifying

0.5p + -3.45 = -1.2

Reorder the terms:

-3.45 + 0.5p = -1.2

Solving

-3.45 + 0.5p = -1.2

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '3.45' to each side of the equation.

-3.45 + 3.45 + 0.5p = -1.2 + 3.45

Combine like terms: -3.45 + 3.45 = 0.00

0.00 + 0.5p = -1.2 + 3.45

0.5p = -1.2 + 3.45

Combine like terms: -1.2 + 3.45 = 2.25

0.5p = 2.25

Divide each side by '0.5'.

p = 4.5

Simplifying

p = 4.5

Answer:

Step-by-step explanation:

Cone

Givens

r = 1.5 inches

h = 4 inches

Formula

V = 1/3 pi r^2 h

V = 1/3 3.14 * 1.5^2 * 4

V = 1/3* 3.14 * 2.25 * 4

V = 9.42

Semi sphere

Givens

r = 1.5

Formula

V = 2/3 * pi * r^3

Solution

V = 2/3 * 3.14 * 1.^3

V = 7.065

Total

V = 9.42 + 7.065

V = 16.485

Rounded to the nearest 1/100

V = 16.49

Find x and the measure of each side. Round to two decimal places, if necessary.
natta225 [31]

The values of the triangles are as follows:

  • x = 7 units
  • GH = 21 units
  • HI = 21 units
  • GI = 12 units

<h3>How to find angles and side of a triangle?</h3>

The triangle is an isosceles triangle because two sides and angles are equal. Therefore,

4x - 7 = 2x + 7

4x - 2x = 7 + 7

2x = 14

x = 14 / 2

x = 7 units

GH = 4(7) - 7 = 28 - 7 = 21

HI = 2(7) + 7 = 14 + 7 = 21

GI = 7 + 5 = 12
