Answer:
shaded area = 601 mm²
Step-by-step explanation:
Area of rectangle = Length * Breadth
Area of first section = 12 * 16 = 192 mm²
Area of 2nd middle section = 8 * ( 16 - 10 ) = 48 mm²
Area of the bottom section = 19 * 19 = 361 mm²
Area of total therefore = 192 mm² + 48 mm² + 361 mm²
= 601 mm²
Answer:
250 cubic centimeters of water
Step-by-step explanation:
In this question, we are asked to calculate the volume of water in cubic centimeters given to each of the plants.
The total volume of water is 3 * 1 = 3 liters of water
Now 12 plants was watered, this means the amount of water used on each plant would be 3/12 = 0.25 liters
Answer is wanted in cubic centimeters. This means that we will have to convert.
Mathematically;
1L = 1000 cubic centimeters
0.25 L is thus 0.25 * 1,000 = 250 cubic centimeters
Answer:
<h2>0.05x+11<27 for x<=320</h2>
Step-by-step explanation:
Step one:
Plan 1
charges = $27 monthly
the total charges is expressed as
y=27------1
Plan 2
charges= $11 monthly
extral= $0.05 per call
let x be the number of calls
the total is expressed linearly as
y=0.05x+11--------2
Step two:
equating 12 and 2 we have
27=0.05x+11
collect like terms
27-11=0.05x
16=0.05x
divide both sides by 0.05
x=16/0.05
x=320
the inequality for which plan A is more economical is
0.05x+11<27 for x<=320
Answer:
Lay the proper scale next to the item on the drawing and take the measurement. The scale will translate for you. As an example, a 1/4 inch = 1 foot architect scale will have markings that increase by 1 foot every 1/4 inch; a 4 foot wall is represented by a 1-inch length, if measured with a conventional ruler.
