MIDDLE SCHOOL MATH On the subway 8 out of 10 people are carrying a briefcase. Based on this information, if there are 700 people on the subway, then about how many do NOT have a briefcase?
Answer:
140
Step-by-step explanation:
If 8 out of 10 are carrying a briefcase, that means 2 out of 10 are not carrying one.
Use a proportion to find how many don't have a briefcase with 700 people
Let x represent the number of people without a briefcase:
[tex]\frac{2}{10}[/tex] = [tex]\frac{x}{700}[/tex]
Cross multiply and solve for x
10x = 1400
x = 140
So, 140 people do not have a briefcase
Answer:
140
Step-by-step explanation:
8/10 people, there's 700 people
10 multiplied by 70 =700.
2 people dont have briefcases = 2 times 70=140

The circumference of a circle is 23 pi M what is the area in square meters express your answer in terms of pie
Answer:132.25π m²
Step-by-step explanation:The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius. Then by equating the last two expressions we get: 23π = 2πr then r = 23/2 then the area = π × r² = (23/2)²×π = (132.25)×π

Find the volume of a cone with a base radius of 6 in and a height of 12 in. Write the exact volume in terms of , and be sure to include the correct unit in your answer.
Answer:
we have
radius [r]=6in
height [h]=12in
Volume of cone = 1/3πr²h
Volume = 1/3 ×π × (6)² × 12=144πίn³or 452.38in³ is your answer.

Mrs. Soto is putting 3 tables together to make 1 long table with a total length of 250 centimeters. The first table has a length of 83 centimeters. The second table has a length of 0.9 meter. How many meters (m) long is the third table?
Hello. I hope this helps!
Let's set up an equation for this.
1st table = 83 cm
2nd table = 90 cm OR 0.9 m
3rd table = x
Total length = 250
Equation:
83 + 90 + x = 250
Now we'll solve the equation.
83 + 90 + x = 250
173 + x = 250
x = 250 - 173
x = 77 cm
