A rectangular picture measures 6 inches by 9 inches. If a copy machine makes each of the two dimensions 113 larger, by what is the percent of increase in the area of the picture
Answers
Answer:
27.7% larger
Step-by-step explanation:
6 x 113% = 6.78
9 x 113% = 10.17
Old Area = 9 x 6 = 54 sq in
New Area = 6.78 x 10.17 = 68.95
(New - Old) ÷ Old = .277 = 27.7%

What transformation was not done to the linear parent function, f(x) = x, to get the function g(x) = - 1/2(x+5) +7
Answers
Answer:
b; vertically compressed by a factor of 2
Step-by-step explanation:
Here, we want to select from the options, the transformation that was not done on the parent function;
a) shifted up seven units
This was done
as we can see, we have + 7 from the initial 0 point
b) vertically compressed by a factor of 2
This is wrong
What we had is 1/2 multiplied by x
If there is any compressor done, it is to a factor of 1/2 and not 2
This, is thus our answer

What is the length of the hypotenuse?
C =
yards
Answers
Answer:
The length of the hypotenuse is 10 yards.
Step-by-step explanation:
Given that this is a right triangle, you could apply the Pythagorean Theorem to it. Although I'm not exactly sure, given as there's no indication in your question.
The Pythagorean Theorem is a^2 + b^2 = c^2, for context.
So, 6^2 + 8^2 = ?^2.
6^2 = 36
8^2 = 64
64 + 36 = 100
However, 100 isn't the side length of c, it's c squared. To "unsquare" it, you need to find the square root of it.
In this case, the square root of 100 is 10.
6^2 + 8^2 = 10^2. Makes sense, right?
36 + 64 = 100
Hope this helps.

[tex] \tt \dfrac{x}{120} = \dfrac{65}{50} [/tex]
[tex] \tt \: x = \dfrac{120 \times 65}{50} [/tex]
X = 156 ftFind the percent of increase or decrease
x to 5x
Answers
Answer:
Step-by-step explanation:
The percentage increase from x to 5x is given by the equation P = 400 %
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage increase be P
Now , the equation will be
Let the original value be = A
The value of A = x
Now , the increased value = B
The value of B = 5x
And , the percentage increase is given by the equation ,
P = ( ( Increased value - Original value ) / Original value ) x 100 %
Substituting the values in the equation , we get
The percentage increase P = ( ( 5x - x ) / x ) × 100 %
The percentage increase P = ( 4x/x ) × 100 %
The percentage increase P = 4 x 100 %
The percentage increase P = 400 %
Therefore , the value of P is 400 %
Hence , The percentage increase from x to 5x is 400 %

One-half of a cake is divided equally among 4 people at a party. What
fraction of the cake
Answers
Answer:
1/8
Step-by-step explanation:
One half of the cake is four slices, and the entire cake (if it was all there) would be 8 slices. For the four slices to be distributed equally among the four people, each person gets 1 slice. 1 slice out of the 8 total in the cake would be 1/8 of the whole.
Answer:
Each person will get 1/8 of the whole cake but 1/4 of half of the cake.
Step-by-step explanation:
Since the cake is cut in half and then in fourths, you need to multiply 1/4 by 1/2 and get 1/8.

b) first quartile = 17
c) median = 22.5
d) third quartile = 26.5
e) maximum = 32
e) interquartile range = 26.5 - 17 = 9.5
Step-by-step explanation:
minimum and maximum values are self-explanatory
first quartile is derived by getting the median of the lower half of data (the median will divide the data into the lower half and the upper half)
third quartile is derived by getting the median of the upper half of data
the median is sometimes referred to as the second quartile
box plots are all about quartiles so that you can see where 25% of the data reside, or 50% or 75%, etc
What is the length of the hypotenuse? 1. 52 + 122 =c2 2. 25 + 144 =c2 3. 169=c2 c=
Answers
Answer:
Step-by-step explanation:
In order to solve this question we need to know that [tex]a^{2} + b^{2} = c^{2}[/tex] (were a and b are the legs of a right angle triangle and c is the hypotenuse). Now since we are given [tex]a^{2}[/tex] and [tex]b^{2}[/tex],we can solve for hypotenuse in each case. So we do......
1) 52 + 122 = [tex]c^{2}[/tex]
174 = [tex]c^{2}[/tex]
[tex]\sqrt{174} =c[/tex]
13.190905 ≈ c
2) 25 + 144 = [tex]c^{2}[/tex]
169 = [tex]c^{2}[/tex]
[tex]\sqrt{169} = c[/tex]
[tex]13 = c[/tex]
3) 169 = [tex]c^{2}[/tex]
[tex]\sqrt{169} = c[/tex]
[tex]13 = c[/tex]

What is a hypotenuse?A hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.
Given that, A right triangle has side lengths 5 inches and 12 inches.
Using Pythagoras theorem,
h = √5²+12²
h = √25+144
h = √169
h = 13
Hence, the length of the hypotenuse 13 units.
