Answer 1

Answer:

The requried solution for each percentage is
1. 350 is 70% of 500 2. 37.5% of 64 is 24
3. 40% of 6.50 is 2.60 4. 20 of 140 is 28.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
We have to determine a number, whose 70% is 350
Let eh number x,

According to the question,
70% of x = 350
x = 350/ 70%
x = 350/0.70
x = 500

Similarly,
37.5% of 64 is 24
40% of 6.50 is 2.60
20 of 140 is 28.

Thus, the requried solution for each percentage is shown above.

Answer 2

Answer: learn this , it will help u with all of these percent problems.
percent formula : is/of = %/100

350 is 70% of what number....
is = 350
% = 70
of = x
now sub
350/x = 70/100
cross multiply
70x = 35000
x = 35000/70
x = 509....so 350 is 70% of 500.
=====================
is/of = %/100

what percent of 64 is 24...
% = x
is = 24
of = 64
now sub
24/64 = x/100
cross multiply
64x = 2400
x = 2400/64
x = 37.5..so 37.5% of 64 is 24
====================
u get the idea....
the last 2 answers are : 40% and 28

A telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $155 for 100 megabytes and $245 for 200 megabytes. An equation can be written to show the relationship between the total megabytes of data used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph? Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 0.9 Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 1.1 Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 1.1 Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

Answers

Answer:

Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9

Step-by-step explanation:

x variable represents total megabytes of data used

y variable represents total monthly charges

The company charges $155 (y) for 100 megabytes (x) means that the point (100, 155) belongs to the equation.

The company charges $245 (y) for 200 megabytes (x) means that the point (200, 245) belongs to the equation.

With these two points, the slope is computed as follows:

(245 - 155)/(200 - 100) = 0.9

A house on the land measures 45 feet by 38 feet,a wooded area covers 118 feet by 60 feet,and the front yard is 78 feet by 40 feet.The remainder of the land is farmed.How many acres of land are farmed?Round to the nearest tenth.Explain your answer.(Hint: 1 acre = 43,560 square feet)

Answers

The figure is composed of 2 shapes. A rectangle and a right triangle.

Area of the Rectangle = 600 ft * 200 ft = 120,000 ft²
Area of the right triangle = (600 ft * 450 ft)/2 = 270,000 / 2 = 135,000 ft²

Total area = 120,000 ft² + 135,000 ft² = 260,000 ft²

Area of the house = 45 ft * 38 ft = 1,710 ft²
Area of the woods = 118 ft * 60 ft = 7,080 ft²
Area of the front yard = 78 ft * 40 ft = 3,120 ft²

Area of farmed land = 260,000 - 1,710 - 7,080 - 3,120 = 248,090 ft²

248,090 ft² * 1acre/43,560 ft² = 5.695 acres
