One week, the ratio of pounds of apples to pounds of oranges sold at a market was 3:8. Twelve pounds of apples were sold. how ma
Minchanka [31]
3 : 8....can be written as 3/8
12 lbs of apples were sold

apples / oranges : 3/8 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (12)(8)
3x = 96
x = 96/3
x = 32 <=== 32 lbs of oranges

notice that 3/8 = 12/32....these are equivalent fractions....because that is what proportions are, equivalent fractions

Landscape artists frequently hand-draw their landscape layouts (blueprints) because this allows them more creativity and precisi
ra1l [238]

The information given about the landscape is illustrated below:

<h3>How to explain the landscape?</h3>

a. You'll need a measuring tape, two range poles, pegs, and three people.

The first person holds the zero mark between their thumbs and fingers, the second person holds the 3m mark on the tape between their thumbs and fingers, and the third person holds the 8m. When all sides of the rope are stretched, a triangle is created, and an angle near one is a right angle.

Wrap one loop of the rope around peg A with a peg through the other loop, draw a circle on the ground, place pegs B and C where the circle crosses the base line, and place peg D half way between pegs B and C, allowing pegs D and A to form lines perpendicular to the base line, forming a right angle.

B. <u>Method 1; </u>Take a measurement of the distance between both trees and divide by 2 to get the midpoint.

<u>Method 2;</u> By use of a compass to bisect the distance between both points.

Method 3; By using a protractor to mark the 90° vertical point when placed between the two endpoints.

C The three different ways he can do this.

1) by using a protractor

2) by finding a point

3) by extending the line of the angle until it reaches the other side of the field.
