A ratio shows us the number of times a number contains another number. The ratio of DE to EF is 3:2. The ratio of DE to EF is 3:1.
What is a Ratio?A ratio shows us the number of times a number contains another number.
1.)
DE = √(6² + 3²)
= √45
= 3√5
EF = √(4² + 2²)
= √20
= 2√5
Ratio = 3√5 / 2√5 = 3/2
Hence, the ratio of DE to EF is 3:2.
2.)
PQ = √(6² + 3²)
= √45
= 3√5
QR = √(1² + 2²)
= √5
Ratio = 3√5/√5 = 3:1
Hence, the ratio of DE to EF is 3:1.

What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the equation of the graph be represented as A
Now , the value of A is
Since the graph is that of a parabolic curve ,
It is a quadratic equation of the form y = ( x + a )² - b
And , the graph is shifted right to 4 units and down by 3 units
So , the equation of graph is G ( x ) = ( x + 4 )² - 3

The perimeter of a book is 70cm. Its length is 20cm. What is the width?
Answers
The perimeter of an object is the sum of all sides.
a book is a rectangle which has 4 sides. 2 sides would be the length and 2 sides would be the width.
Set up the equation:
70 = 20 + 20 + x + x

70 = 40 + 2x
Subtract 40 from both sides
30 = 2x
Divide both sides by 2

Can someone please help me
Answers
Answer:
(3, 0)
Step-by-step explanation:
So with the 2 equations you can either choose which to start with but you need to make the X or Y the opposite from the other equation.
1.
3x + y = 9 (keep as is)
x + 2y = 3 --> -3( x + 2y = 3) In this case I chose to make the X the opposite of each other
--
3x - 3x = 0 (forced to get rid of)
y - 6y = -5y (Get the -6 by -3 x 2)
9 - 9 (Get the -9 by -3 x 3)
Left with:
-5y = 0 (Divide both sides by -5 to get X alone)
y = 0
----------------------------------------------------------
(Choose any ORIGINAL equation)
x + 2y = 3
x + 2(0) = 3 (substitute)
Left with:
x = 3 (x + 0 = 3)
-------------------------------------------------------------
Optional:
Chose the other equation (the opposite from above)
Substitute X and Y in 3x + y = 9
3(3) + (0) = 9
Left with: 9 = 9 (check)

Suppose a city with population 800,000 has been growing at a rate of 5% per year. If this rate continues, find the population of this city in 22 years
Answers
Answer:
2,340,208.5 or 2,340,209
Step-by-step explanation:
You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times. But that would take a while.
we got 1.05 because the formula says that y = a( 1 + r ) power t
for a we will give it 1
so y = 1 ( 1 + 0.05) power t
it will give us 1.05
to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.
So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209

which interest rate and time would result in the lowest total loan repayment for a %50,000 loan earning simple interest?
A. 30 years at 3%
B.25 years at 3.5%
C.15 years at 6%
D 20 years at 4.5%
Answers
Answer: Choice B
Explanation:
Convert each percentage mentioned to decimal form. Example: 3% = 0.03
Then multiply each time value with the decimal form of the interest rate.
A) 30*0.03 = 0.9B) 25*0.035 = 0.875C) 15*0.06 = 0.9D) 20*0.045 = 0.9Choice B yields the smallest result, so it will lead to the lowest amount of interest to pay on top of the principal. Therefore, option B is the best route to have the lowest total repayment.

Harry took out an 80/20 mortgage to buy a house costing $175,000. The first
(80%) mortgage has an interest rate of 4.75%, and the second (20%)
mortgage has an interest rate of 7.525%. Both the first mortgage and the
second mortgage are 30-year fixed-rate mortgages. What is his total
mortgage payment for this house?
Answers
Answer:
WEll the answer is d
Step-by-step explanation:
The first (80%) mortgage has an interest rate of 4.75%, and the second (20%) mortgage has an interest rate of 7.525%. Both are 30-year fixed-rate mortgages.
======================================================
Explanation:
The formula we'll be using is
P = (L*i)/( 1-(1+i)^(-n) )
where,
P = monthly paymentL = loan amounti = interest rate per month in decimal formn = number of months---------------------
For the first mortgage (80%), we need to find out the L value
L = 80% of 175,000 = 0.80*175,000 = 140,000
The monthly interest rate is the annual rate over 12
i = r/12 = 0.0475/12 which I'll keep as a fraction
Lastly, this mortgage goes for 30 years aka 30*12 = 360 months. So n = 360.
To summarize the input values we'll use, we have,
L = 140,000i = 0.0475/12n = 360Let's compute the monthly payment
P = (L*i)/( 1-(1+i)^(-n) )
P = (140,000*0.0475/12)/( 1-(1+0.0475/12)^(-360) )
P = 730.30627110436 approximately
P = 730.31
The first mortgage has a monthly payment of $730.31
We'll use this later.
---------------------
Now onto the second mortgage (20%)
L = 20% of 175,000 = 0.20*175,000 = 35,000
i = r/12 = 0.07525/12 which I'll keep in fraction form
n = 360 months (same as before)
In short,
L = 35,000i = 0.07525/12n = 360So,
P = (L*i)/( 1-(1+i)^(-n) )
P = (35,000*0.07525/12)/( 1-(1+0.07525/12)^(-360) )
P = 245.32451498724 approximately
P = 245.32
The second mortgage has a monthly payment of $245.32
---------------------
The last step is to add the two monthly payments (found at the conclusion of each previous section)
730.31 + 245.32 = 975.63

What is the justification for step 2 in the solution process?

Step 1: 1/2r+1/2=-2/7r-29/7
Step 2: 1/2r=-2/7r-65/14
A.) The subtraction property of equality
B.) The multiplication property of equality
C.) The division property of equality
D.) The addition property of equality
Answers
Answer:
Option AStep-by-step explanation:
At Step 2 you subtract 1/2 from both sides of the equation:
1/2r = - 2/7r - 29/7 - 1/21/2r = - 2/7r - 58/14 - 7/141/2r = - 2/7r - 65/14Its justification is therefore is:
A) The subtraction property of equalityCan you solve (x-2)(x+3) = 5 by solving x - 2 =5 and x + 3 =5? Why or why not?
Answers
Answer:
no we cannot because when we solve x-2=5 it gives x=7 and x+3=5 gives x=2 if we place the x value as 7 then it does not justify (x-2)(x+3)=5, if we put x= 2 then again it does not justifies (x-2)(x+3)=5
Step-by-step explanation:
x-2=5
x=5+2
x=7
x+3=5
x=5-3=2
putting x=7 in given equation
(7-2)(7+3) is not equal to 5
putting x=2 in given equation
(2-2)(2+3) is not equal to 5
that's why we can't solve

Answers
Charlene’s new net income will be $113.70.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the monthly salary of Charlene is $3,410. While her net income is 7% of her monthly income. Therefore, the net income of the Charlene is
[tex]7\%\ of\ \$3410 = \text{Charlene Net income}\\\\\dfrac{7}{100} \times 3410 = \text{Charlene Net income}\\\\ \text{Charlene Net income} = \$238.7[/tex]
Thus, Charlene's net income is $238.7.
Now since Charlene is going to reduce her net income by $125 each month, therefore,
Charlene New Net Income = Charlene Net Income - $125
= $238.7 - $125
= $113.70
Hence, Charlene’s new net income will be $113.70.
