Help me with a. b. c. I need help

hammer [34]

Answer:

a) Perimeter = 20.5 Inches

Area is 15 Sq Inches

b) Perimeter is 61.4 Cms

Area is 210 Sq cm

c) Perimeter is 22 yards

Area is 21 Sq Yards

Step-by-step explanation:

a) Perimeter = sum of all the sides

= 8+7.5+5

=20.5

Perimeter = 20.5 Inches

Area of Triangle = $\frac{1}{2} \times height \times Base$

Base = 7.5 In

Height = 4 In

$A = \frac{1}{2} \times 4 \times 7.5$

$A = 2 \times 7.5$

$A = 15$

Hence Area is 15 Sq Inches

b) Perimeter = Sum of all the sides

P=13+23+13.4+12

P=61.4

Perimeter is 61.4 Cms

Area of trapezium = $\frac{1}{2} \times height \times (sum \ of \ parallel \ sides)$

$A= \frac{1}{2} \times 12 \times (12+23)$

$A= 6 \times 25$

$A=210$

Area is 210 Sq cm

c) Perimeter = Sum of all the sides

P = 7+4+7+4 ( as Opposite sides are equal in a parallelogram

P = 22

Perimeter is 22 yards

Area of a parallelogram = $base \times height$

$A= 7 \times 3$

$A = 21$

Area is 21 Sq Yards

There are about 1.4×109 cubic kilometers of water on Earth. About 2.5% of the water is fresh water. How much fresh water is on E

Sveta_85 [38]

Answer:

Amount of fresh water = 3.5 * 10^7 cubic kilometers

Step-by-step explanation:

Given the following

Total water on earth = 1.4×10^9 cubic kilometers

If 2.5% of it is fresh water

Amount of fresh water = 2.5% of 1.4×10^9

Amount of fresh water = 0.025 * 1.4×10^9

Amount of fresh water = 0.035 * 10^9

Amount of fresh water = 3.5 * 10^7 cubic kilometers

Billy's age is twice Joe's age and the sum of their ages is 45. How old is Billy?

Fed [463]

Answer:

30 years old

Step-by-step explanation:

Joe's age can be set to x. Since Billy is twice as old as Joe, his age can be set to 2x. They add up to 45. You can set up an equation, 2x+x=45.

Simplify the equation.

3x=45, x=15

Joe is 15. Billy is 2(15)=30.
