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

slope: 10 m/srepresents speed in meters per secondStep-by-step explanation:
The slope is the change in the quantity on the vertical scale, divided by the corresponding change in the quantity on the horizontal scale.
Here, the line goes from 0 to 100 meters on the vertical scale, corresponding to a change from 0 to 10 seconds on the horizontal scale. So, the slope is ...
m = (100 m)/(10 s) = 10 m/s . . . . slope of the line
The ratio of distance to time is given the name "speed", so ...
the slope represents the sprinter's speed in meters per second.

The corner store sells one of its magazines for $ 6.75 including tax. On one weekend the store collected $ 114.75nfrom the sale of this particular magazine. What expression can be used to find the number of magazines, n, sold by the store for that weekend?
6.75÷114.75=n
6.75÷n = 114.75
6.75n=114.75
6.75 + n= 114.75

Answer:
(c) 6.75n=114.75
Step-by-step explanation:
If one magazine sells for 6.75, then n magazines will sell for a total of 6.75n. That total is said to be 114.75, so we have ...

What is the value of n??
9514 1404 393
Answer:
73.6°
Step-by-step explanation:
The whole is the sum of the parts:
n = 44.5° +29.1°
n = 73.6°
Answer and Step-by-step explanation:
To find the value of n, we must add the two given angles first.
Why?
We add these two angles together because we are shown that angle n encompasses both angles, meaning that the value of n must be the combination of the angles added together.
29.1 + 44.5 = n
Add.
73.6° = n
The value of n is 73.6°.

Hey please help with this one I promise I’ll mark you brainliest real anwsers tho :3
Answer:
Area is 364
Step-by-step explanation:
A parallelogram's area is equal to base times height. So it doesn't depend on the angle at all, as long as the base and height are constant.
That means that the area of the parallelogram on the left is the same as if it was a rectangle (an extension of the rectangle part on the right).
This brings us to the answer - the area is the same as the area of a 14x26 rectangle.
14*26=364
Alternatively, let's compute the area of the rectangle on the right:
18*14 = 252
And the area of the parallelogram
14 * (26-18) = 14*8 = 112
And the area of the composite figure is 252+112 = 364
Ans: 720cm

The ratio of the number of Malay students to the number of Indian students to the
number of Chinese students in a school is 5:4:8.
There are a total of 468 Indian and Chinese students.
What is the total number of students?
Ans:
Answer:
663
Step-by-step explanation:
the total number of students can be determined using this equation :
(total ratio of Chinese and Indian students / total ratio of students) x n = 468
total ratio of Chinese and Indian students = 4 + 8 = 12
total ratio of students 4 + 8 + 5 = 17
N = TOTAL NUMBER OF STUDENTS
12/17) x n = 468
multiply both sides of the equation by 17/12
n = 663
Find the circumference and the area of a circle
with the dimensions listed. Use the value 3.14 for π
,and do not round your answers. Be sure to
include the correct units in your answers.
a) diameter of 3 cm
b) radius of 5 ft
In response to the question, we may say that As a result, the radius of the circle is 9.42 cm and its area is 7.065 cm sq
What is circle?A circle seems to be a two-dimensional component that is defined as the collection of all places in a jet that are equidistant from the hub. A circle is typically shown with a capital "O" for the centre and a lower portion "r" for the radius, which represents the distance from the origin to any point on the circle. The formula 2r gives the girth (the distance from the centre of the circle), where (pi) is a proportionality constant about equal to 3.14159. The formula r2 computes the circumference of a circle, which relates to the amount of space inside the circle.
a) 3 cm diameter: The radius (r) of a circle is half its diameter, hence r = 3 cm/2 = 1.5 cm
The formula C = 2r gives the circumference of a circle, where is approximately equivalent to 3.14.
As a result, C = 2 3.14 1.5 cm = 9.42 cm.
The formula A = r2 calculates the area of a circle.
As a result, A = 3.14 (1.5 cm)2 = 7.065 cm sq.
As a result, the radius of the circle is 9.42 cm and its area is 7.065 cm sq
