If we multiply 0.8 by 1/50, we get 0.8 × 1/50 = 0.8/50 = 0.016 meter. So, we can say 0.016 meter wide should the door be on the scale drawing, if the ratio is 1 to 50.
Answer:
the ratio is 1:50
this means that 1 meter in the drawing is equal to 50 meters in real life, but that is a complicated way of stating something simple since drawings are not generally measured in meters.
the door is 0.8 meters wide or 80 centimeters wide
in our drawing, the door should be 80 / 50 = 1.6 centimeters wide
the whole purpose of a scale is to allow us to work with smaller units, that is why we have to work with them. It is true that 0.016 meters = 1.6 centimeters, but as I said before, writing the answer in meters just complicates things and makes them harder to understand. You could also say it is 0.000016 kilometers wide and it would be right, but too confusing.
Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the number of minivans sold each week.
Answer:
An inequality 'c ≥ 5' represents this situation.
Step-by-step explanation:
We know that the inequality symbol '≥' represents 'at least'.
For example, 'x≥y' means 'x' is greater than or equal to b. It means 'x' is at least equal to 'y'.
Let 'c' represent the number of minivans sold each week.
As a car dealer ship sells at least 5 minivans. It means the dealer can also sell more than 5.
i.e. c ≥ 5
Therefore, an inequality 'c ≥ 5' represents this situation.
What is the point-slope form of an equation for a line that passes through the point (5, –5) with the slope of 2?
Answer:
y + 5 = 2(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (5, - 5) , thus
y - (- 5) = 2(x - 5) , that is
y + 5 = 2(x - 5)

A balalaika is a Russian stringed instrument. Show that the triangular parts of the two balalaikas are congruent for x = 6.
*the diagram of the Russian stringed instrument is attached below.
Answer/Step-by-step explanation:
To show that the traingular parts of the two balalaikas instruments are congruent, substitute x = 6, to find the missing measurements that is given in both ∆s.
Parts of the first ∆:
WY = (2x - 2) in = 2(6) - 2 = 12 - 2 = 10 in
m<Y = 9x = 9(6) = 54°.
XY = 12 in
Parts of the second ∆:
m<F = 72°
HG = (x + 6) in = 6 + 6 = 12 in
HF = 10 in
m<G = 54°
m<H = 180 - (72° + 54°)
m<H = 180 - 126
m<H = 54°
From the information we have, let's match the parts that are congruent to each other in both ∆s:
WY ≅ FH (both are 10 in)
XY ≅ GH (both are 12 in)
<Y ≅ <G (both are 54°)
Thus, since two sides (WY and XY) and an included angle (<Y) of ∆WXY is congruent to two corresponding sides (FH and GH) and an included angle (<G) in ∆FGH, therefore, ∆WXY ≅ ∆FGH by the Side-Angle-Side (SAS) Congruence Theorem.
This is enough proof to show that the triangular parts of the two balalaikas are congruent for x = 6.

Xiaoming is making cookies. Each batch of cookies uses3 eggs. If Xiaoming has 20 eggs, and assuming he has enough of the other ingredients to make the cookies what is the greatest number of batches that he can make ?
Answer:
6
Step-by-step explanation:
3(1)=3 3(2)=6 3(3)=9 3(4)=12 3(5)=15
3(6)=18 3(7)=21 3(8)=24
----------------------------------------------------
3(6)=18 is closest to 20
so the greatest number of batches Xiaoming can make is 6.
Explain why when dividing fractions with the same denominator, you can find the quotient by dividing the numerators. Support your answer with an example using one or more mixed numbers.
By dividing fractions with the same denominator, you can find the quotient as the same as numerators.
To explain when dividing fractions with the same denominator, you can find the quotient to as the same as the numerators.
Here,
Let's assume a fraction a / b
While dividing the fraction a / b with the fraction with the same denominator 1 / b,
= a / b ÷ 1 / b
While dividing the fraction by another fraction then the result shows the fraction as multiplication of the numerator of one fraction with the denominator of another fraction over the multiplication of the denominator of one fraction with the numerator of another fraction.
= a / b * b / 1
= a
Thus, by dividing fractions with the same denominator, you can find the quotient as the same as numerators.

A manufacturing plant has 60
supervisors. If 27 of the supervisors are
men, then
O 45% are women
55% are men
55% are women
O 75% are men
O 75% are women
Answer:
55% are women
Step-by-step explanation:
27÷60= 0.45
0.45x100=45
100-45=55
45% men
55% women
There are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have:
A manufacturing plant has 60 supervisors. If 27 of the supervisors are men.
The number of women = 60 – 27 = 33
The percent of women = (33/60)×100
= 0.55×100
= 55%
Thus, there are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

insert three arithmetic means between 7 and 15
Answer:
9, 11 , 13
Step-by-step explanation:
Find the average of 7 and 15, that is
[tex]\frac{7+15}{2}[/tex] = [tex]\frac{22}{2}[/tex] = 11
We now have 7, 11, 15
Now find the average of 7 and 11, 11 and 15
[tex]\frac{7+11}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9
[tex]\frac{11+15}{2}[/tex] = [tex]\frac{26}{2}[/tex] = 13
Thus the 3 arithmetic means between 7 and 15 are

An item is originally priced 68.89 dollars. It was on sale for 42 percent of the original price. Which is an estimate of the sale price? A. 2.00 dollars B.3.50 dollars C. 20 dollars or D. 28 dollars.
Answer:
D. 28 dollars
Step-by-step explanation:
42% = .42
"of" means to multiply
68.89 × .42= 28.9
28 is the closest answer.
Answer:
The answer would be D.28 dollars
Step-by-step explanation:
Its 28 dollars because,
Discount = Original Price x Discount %/100
Discount = 68.99 × 42/100
Discount = 68.99 x 0.42
You save = $28.98
Final Price = Original Price - Discount
Final Price = 68.99 - 28.9758
Final Price = $40.01
