3 meters of cloth is the ratio of 3:7
When given 3 meters of cloth to divide in the ratio 3 : 7 then one part of the division will have 0.9 meters and the other side will have 2.1 meters.
How to use ratio to divide?The ratio is 3 : 7 which means that the 3 meters of cloth should be divided such that one part is 3 to the 7 of the other part.
First, find the denominator:
= (3 + 7)
= 10
The smaller part of the cloth:
= 3 / 10 x 3 meters of cloth
= 9 / 10 meters
= 0.9 meters
The larger part of the cloth:
= 7 / 10 x 3 meters of cloth
= 21 / 10
= 2.1 meters

Answer:
True
Step-by-step explanation:
When data is skewed toward the high or low end, the mean can be a misleading measure of central tendency. In such a case the central tendency for the data items shifts toward either the high or low end -- away from the mean. The median then becomes the better measure.
The mean could be misleading when we don't know the spread of data items is to be considered as the true.
Role of mean:
The mean do have the high impact on the extreme observations. In the case when the observation is high so automatically the remaining observations should be low due to which the mean should be increased.
So based on this, we can conclude that The mean could be misleading when we don't know the spread of data items is to be considered as the true.

A student graphs 5x−y=7 on a coordinate plane. Which equation, when graphed on the same coordinate plane, will result in a system of equations with no solution? 5x−y=7 5 x − − y = 7 5x−y=1 5 x − − y = 1 x−5y=35 x − − 5 y = 35 x−5y=5
Answer:
5x−y=1
Step-by-step explanation:
An equation is a statement that shows the equality between two expressions.
An equation is said to have no solutions if after solving the equation and the result is a statement like a = b, where a and b are different numbers.
The equation after it is simplified would have the same coefficients and different constant.
Given:
5x−y=7
An equation that will result in a system of equations with no solution will have the same coefficient but different constant.
Hence 5x−y=1, would give a system of equations with no solution.
Simplifying gives:
7 = 1 (no solution)

Answer: 112 degrees
Step-by-step explanation:
The angles have the same measure because of the corresponding angles theorem.
[tex]\huge\boxed{112^\circ}[/tex]
To solve this problem, we need to understand the basic rules of transversals across parallel lines.
When a line crosses another line or lines, it is a transversal.
When the two lines it crosses are parallel, the eight angles formed have interesting properties that we can use.
For this question, we will look at corresponding angles. If two angles meet these two conditions, they are congruent:
Both angles are on the same side of the transversal.One angle is interior (between the parallel lines) and the other is exterior.These two conditions are met for [tex]\angle JIK[/tex] and [tex]\angle GFI[/tex], so they are congruent and their measures are equal.
This means that [tex]m\angle JIK=m\angle GFI=\boxed{112^\circ}[/tex]

The scale factor of a model plane to the actual plane is 1 to 20.
Find the wing area of the model if the wing area of the actual plane is 400 ft^2
Answer:
1 ft²Step-by-step explanation:
The scale factor = 1 : 20
The area is the product of two dimensions, so the area of the model part to actual part is:
1 ² : 20 ² = 1 : 400If the actual plane has wing area of 400 ft², then the model will have wing area:
400 ft² / 400 = 1 ft²Hannah estimated that a bottle could hold 2.2 liters. The actual volume of the bottle was 2 litters. What was the percent error in hannas measurements?
Answer:
I dont have a direct answer but i think i can help.
Step-by-step explanation:
For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.
