6th grade maths easy help!
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]
A store buys a piano from the vendor for $6000 then marks the price up 15% before they sell it to the public. What is the retail price of the piano?
Answer:
$6900
Step-by-step explanation:
Lets find 15% of 6000 first.
6000 x 15% = 900
So just add 900 now to 6000
6000 + 900 = 6900
Hope this helps!
Answer:
6900
Step-by-step explanation:
first you get 6000 times 15
then you get 900 and then add that to the 6000
in order to get 6900

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:
48 inches
Step-by-step explanation:
The perimeter is the distance around the shape. To find it, add the length of each side together. Assuming each side has two small squares, then each side would be 12 inches. Add 12 + 12 + 12 + 12, in order to get 48

Hannah 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.

Dani decides to add the cost of each shirt and the cost of each bag together, and then multiply by seven to find the total cost. Write an algebraic expression for the total cost of the gifts using Dani’s method. Remember, use t and b as your variables. (3 points)
Answer:
Total cost of 7 pair = 7(t + b)
Step-by-step explanation:
Given:
Cost of each shirt = t
Cost of each bag = b
Number of pair = 7
Find:
Total cost
Computation:
Total cost of each pair = t + b
Total cost of 7 pair = 7(t + b)

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)

The mean can be misleading if you don't know the spread of data items. True or false...
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.
