Answer:
50
Step-by-step explanation:
Area of a square = pi(radius squared)
Square root of 25 is 5
Diameter is radius * 2
5 * 2 = 10 (diameter of circle 1)
10 * 5 = 50 (diameter of circle 2)
Blanche bought a 5-year cd for $7100 with an apr of 2.8%, compounded quarterly, but she wants to take all her money out 9 months early. The early redemption fee for the cd is 3 months' interest on the original principal. What is the periodic interest rate of the cd
Answer:
The money she will end up earning in interest on the cd = $11,352.90
Step-by-step explanation:
The formula for getting the accumulated amount(compounded) is;
[tex]A =P(1+\frac{r}{n})^n*t[/tex]
Where
A = Accumulated amount
P = principle (deposit)
r = interest rate and
n = no of times interest applied per time period.
The interest is compounded quarterly so in one year it will be 4 times
In 5 years
n = (5×4)-3 = 17 (as she will withdraw 3 month before the completion of five years)
A = [tex]7100(1+\frac{2.8}{100} )[/tex]^17
= 7100( 1 + 0.028)^17
= 7100(1.028)^17
= 7100 * 1.599
= 11,352.90
Therefore the money she will end up earning in interest on the cd = $11,352.90

If the two triangles shown below are congruent, select the corresponding 1 point
postulate that proves they are congruent. If the triangles are not
congruent, select not congruent. *
Answer:
SSS
Step-by-step explanation:
The two triangles both share a side (the middle line), and it is shown that the other lines are congruent to each other. So all 3 sides are congruent, meaning SSS is the postulate that proves this.

Answer:
y = 4x - 3
Step-by-step explanation:
The values in the x column increase by 1 each time.
The values in the y column increase by 4 each time.
Therefore, the slope of your equation should be 4.
The y-intercept is -3 when x = 0.
The final equation would be:
y = 4x - 3

Answer:
Option A: 6 to 9 , 9/12 is the correct answer.
Step-by-step explanation:
The equivalent ratios simplify to same simple ratio.
In case of this question, we have to check which to the ratios doesn't simplify to 3:4 or 3/4
Option A:
6 to 9 , 9/12
6 to 9 can be written as:
[tex]=\frac{6}{9}\\= \frac{2}{3} \neq \frac{3}{4}[/tex]
9/12 simplifies to 3/4
But as one of the ratio doesn't simplify to 3:4 which means 6 to 9 is not equivalent to 3:4
Hence,
Option A: 6 to 9 , 9/12 is the correct answer.

Answer:
slope of st is -0.25
slope of tu is 1
slope of us is -0.25
slope of sv is 1 so it is a parallelogram. the slope of the parallel lines needs to be the same to be a parallelogram. to find the slope, you need to find the change from the points of the referenced line, for example, slope of st you would label each point as x1, y1 and x2,y2. it does not matter which one you label and you can change them for each different line. you would then find the difference by subtracting (y2-y1) divided by (x2-x1) so 4-3=1 and 1-5 is -4. you then divide 1/-4 is -0.25. you the follow the steps for each line. is the parallel lines have the same slope, it is a parallelogram

Answer:
y=-6/5x - 1
Step-by-step explanation:
Slope intercept form is y=mx+b so first lets get it into correct order by subtracting the 6x to the other side.
6x-6x+5y=-5-6x
This gives you
5y=-6x-5
Now you need to isolate the y since the 5 is being multiplied by the variable "y" we need to divide to to separate. Divide all terms by 5.
5y/5=-6/5x+(-5)/5
This gives you your final answer:
y=-6/5x - 1
Answer:
y= -6/5x +1
Step-by-step explanation:
6x + 5y=5 move variable to right and change the sign
5y =-5 -6x divide both sides by 5...
5y/5 = -5-6x/5
y= -1 -6/5x reorder terms (when yo do you need to change the sign
so the -1 becomes a positive 1.....thats using the communitive
property to reorder terms
5= -6/5x+1

Ravi wants to buy a new guitar that costs $129.99. He has $27, and decides to give music lessons to earn the rest of the money. Ravi decides to charge $22 per lesson. Which inequality would best help Ravi find m, the number of lessons he would need to give in order to buy the guitar?
A. 22m + 27 129.99
The inequality that would help Ravi the best to find m, the number of lessons he would need to give in order to buy the guitar will be 27 + 22 m ≥ 129.99.
Cost of guitar that Ravi wants to buy = $ 129.99
The amount of money that he has = $27
The amount of money that he will get per lesson = $ 22
Let the number of lessons given by Ravi be m.
Now, we know that he has to earn $ 129.99 or more to purchase the guitar.
So, the inequality will become:
27 + 22 m ≥ 129.99
Therefore, we get that, the inequality that would help Ravi the best to find m, the number of lessons he would need to give in order to buy the guitar will be 27 + 22 m ≥ 129.99.

Step-by-step explanation:
a^2 + b^2 = c^2
11^2 + 7 ^2 = c^2
121 + 49 = 170
√170 = 13.04
Answer:
c = 13.0
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
c² = 11² + 7² = 121 + 49 = 170 ( take the square root of both sides )
c = [tex]\sqrt{170}[/tex] ≈ 13.0 ( to the nearest tenth )
Roger completes a quiz with these rules: 5 points are given for each right answer, 2 points are lost for each wrong ans. Roger gets 6 questions correct and 4 questions wrong. What is roger's final score ?
Answer:
The final score of Roger is 22.
Step-by-step explanation:
The final score (F) of Roger is given by:
[tex] F = 5R - 2W [/tex]
Where R is the right answers and W is the wrong answers
Since he gets 6 questions correct (R = 6) and 4 question wrong (W = 4) we have:
[tex] F = 5R - 2W = 5*6 - 2*4 = 22 [/tex]
Therefore, the final score of Roger is 22.
