Answer:
x = 9 cm
y = 30 cm
Step-by-step explanation:
Here, we want to get the lengths of the missing sides
Mathematically if two shapes are similar, the ratio of their corresponding sides are equal
Thus, we have that:
15/50 = x/30
50 * x = 15 * 30
x = (15 * 30)/50
x = 450/50
x = 9 cm
Also;
y/50 = 18/30
30 * y = 50 * 18
y = (50 * 18)/30
y = 30 cm
Convert 6/7 to a decimal. Round to the nearest hundreths.
Answers
Answer:
Step-by-step explanation:
6/7 = 0.8571428571 = 0.86
The fraction 6/7 value in decimal form is 0.86.
To convert the fraction 6/7 to a decimal, you need to divide the numerator (6) by the denominator (7). Here's how you can do it:
Divide 6 by 7: 6 ÷ 7
= 0.8571428571428571 (long division)
To round the decimal to the nearest hundredths, look at the digit in the thousandths place (the third digit after the decimal point).
In this case, the digit is 7.
Since the digit 7 is greater than or equal to 5, we round up the hundredths digit.
The hundredths digit is the second digit after the decimal point.
The rounded decimal is 0.86 (rounded to two decimal places).

Answer:
What is the value of x?
x = 40 degrees.
What is the measure of angle AFE?
Angle AFE = 140 degrees
What is the measure of angle BFD?
Angle BFD = 140 degrees.
Step-by-step explanation:
Angle AFC is 90 degrees.
To find angle x, we have to subtract angle BFC.
90 - 50 = 40 degrees.
Line BFE is 180 degrees.
To find angle AFE, we have to subtract angle x from 180 degrees.
We have solved x already.
180 - 40 = 140 degrees.
Angle BFD is just 90 degrees plus 50 degrees.
90 + 50 = 140 degrees.
Answer:
x = 40
m<AFE = 140
m<BFD = 140
Step-by-step explanation:
1. Finding X
As one can see, AD is a straight line (hence the three angles that add up to is equal 180 degrees). It is given that m<CFD is 90 degrees (signified by the box).
Given;
AD - straight line
m<AFB + m<BFC + m<CFD = 180
( m<AFB, m<BFC, m<CFD form line AD, the degree measures in al ine equal 180, hence m<AFB + m<BFC + m<CFD = 180)
m<BFC = 50
m<CFD = 90 (signified by box around it)
m<AFB + m<BFC + m<CFD = 180 parts whole postulate
x + 50 + 90 = 180 substitution
x + 140 = 180 algebra
x = 40
2. Finding m<AFE and m<BFD
When two straight lines intersect, four angles are formed. The angles that are opposite to each other are called vertical angles, and vertical angles are congruent in other words, have the same measure.
Given;
m<BFD = m< AFE
m<BFC + m<CFD = m<BFD
m<BFC = 50
m<CFD = 90
m<BFC + m<CFD = m<BFD Given (parts whole postulate)
50 + 90 = m<BFD substitution
140 = m<BFD algebra
140 = m<BFD = m<AFE substition

A number is first decreased by 40% and then again decreased by 60%. Find the percentage increase or decrease in the whole sum...please tell quickly
Answers
Answer:
It is decreased by 76 percent.
Step-by-step explanation:
The key skills are percentage and multiplication with percentages.
You first have to get a variable. Let's use the letter o as a variable (o For orginial cost). Then we have to find out how much it is when o is decreased by 40 percent. 100% (or the whole) - 40% is 60%. Therefore, with a 40 percent decrease, It would be 60% of o, or 0.6o. Then, if it decreases by 60 percent, the final number would be 100% - 60 % or 40% of 0.6o. This means itbwould be 0.4 × 0.6o which is 0.24o0.24o means that o is 24 percent of its orginial number, which is 100% - 24% or a 76 percent decrease.Hope you understood and have a nice day!
Which of the following will always be true of a graph that is non-proportional?
please help.
Answers
Given:
Consider any graph that is non-proportional.
To find:
The correct statement that is true of a graph that is non-proportional.
Solution:
We know that, if y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
In these cases if x=0, then y=0. It means the graph always pass through the origin, i.e., (0,0).
So, if a graph is not passes through (0,0), then it is non-proportional.
Thus, non-proportional graph will not pass through (0,0).
Therefore, the correct option is A.
