Answers
The countertop is 8.37 square metersStep-by-step explanation:LetL > the length of the countertopW > the width of the countertopwe know
Answer:
19.83 square meters
Step-by-step explanation:
So, if we are finding the area of a rectangular countertop, we need to multiply the length by the width. A=lw l=length w=width
First, we multiply the length and width of the countertop (13 and 5).
13x5=65 square feet 65 is the area of thecountertop in feet.
Next, we have to multiply that by 0.305 to convert it into meters.
65*0.305=19.825 square meters If we round it, its 19.83 square meters.

long.
How long, in feet, will the table be when the carpenter builds it?
Answers
Using proportions, it is found that the table will be 110 feet long when the carpenter builds it.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In the drawing, 0.75 inches represent 11 feet. The drawing is of 7.5 inches, and the real dimension is of d, hence the rule of three is given by:
0.75 inches - 11 feet.
7.5 inches - d feet
Applying cross multiplication:
0.75d = 7.5 x 11
d = 7.5 x 11/0.75
d = 110.
The table will be 110 feet long when the carpenter builds it.

The scale model of the table would ensure that the actual table is bigger than the scale model
The length of the table would be 110 feet
How to determine the table length?The scale model is given as:
Ratio = Scale : Actual
So, we have:
Ratio = 3/4 inches : 11 feet
For a table of 7 1/2 inches, we have the following ratio
Ratio = 7 1/2 inches : Actual
Equate both ratios
7 1/2 inches : Actual = 3/4 inches : 11 feet
Express as decimals
7.5 inches : Actual = 0.75 inches : 11 feet
Rewrite as:
7.5 : Actual = 0.75 : 11 feet
Express as fraction
Actual/7.5 = 11 feet/0.75
Multiply both sides by 7.5
Actual = 7.5 * 11 feet/0.75
So, we have:
Actual = 110 feet
Hence, the length of the table would be 110 feet

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
The two angles are said to be supplementary angles if their sum is 180 degrees.
By the above property of angle, the equation is written as,
x + 100° + 3x = 180°
Simplify the equation, then we have
x + 100° + 3x = 180°
4x = 80°
x = 80° / 4
x = 20°
The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

Answers
Answer:
The machine takes 25 minutes to make 5 chairs. It would take the machine 160 minutes to make 32 chairs.
Step-by-step explanation:
Divide 2 chairs by 10 minutes to find the amount of chairs made per minute.
2/10 = 0.2 chairs per minute
Divide 5 chairs by 0.2 chairs per minute to find how much time it takes to make 5 chairs.
5/0.2 = 25 minutes
It takes the machine 25 minutes to make 5 chairs.
Divide 32 chairs by 0.2 chairs per minute to find how much time it takes to make 32 chairs.
32/0.2 = 160 minutes
It takes the machine 160 minutes to make 32 chairs.
