Clare is 5 years older than her cousin. cousin How old would Clare be if her cousin is: A. 10 years old? B. 2 years old? C. X years old? Clare is 12 years old. How old is Clare's cousin?
Answers
Answer:
if her cousin is 10 clare will be 15, cousin=2 clare=7, cousin=x clare= x+5. if clare= 12 then 12-5=7
The age of cousin when Clare is 12 years old is computed as 7 years.
What is meant by mathematical operations ?Mathematical operations are defined as the operations used for calculating or computing various solutions of two or more values.
Here,
Given that, Clare is 5 years older than her cousin.
Age of Clare at different ages of her cousin is calculated.
A) 10 years old
Age of Clare = 10 + 5 = 15 years old
B) 2 years old
Age of Clare = 2 + 5 = 7 years old
C) X years old
Age of Clare = X + 5 years old
Cousin's age when Clare is 12 years old can be calculated as,
Age of cousin = 12 - 5 = 7 years old
Hence,
The age of cousin when Clare is 12 years old is computed as 7 years.

So you would square 15 and 8 then add them up to get [tex]c^{2}[/tex]. After this you just need to find the square root of [tex]c^{2}[/tex] to get "c" by itself or in this case "s".

Alice spent $131 on shoes. Flip flops cost $15 and Sneakers cost $28. If she
bought a total of 7 shoes, then how many of each kind of shoe did she
buy? Write the answer as an ordered pair...(flip flops, sneakers). Do not
include the units. *
Answers
Answer:
Flip flops = 5
Sneakers = 2
Step-by-step explanation:
Let
x = flip flops
y = sneakers
x + y = 7 (1)
15x + 28y = 131 (2)
From (1)
x = 7 -y
Substitute x = 7 - y into (2)
15x + 28y = 131
15(7 - y) + 28y = 131
105 - 15y + 28y = 131
-15y + 28y = 131 - 105
13y = 26
y = 26/13
= 2
y = 2
Substitute y = 2 into (1)
x + y = 7
x + 2 = 7
x = 7 - 2
= 5
x = 5
Flip flops = 5
Sneakers = 2

If $1=Rs. 102.50 and £ 1=Rs, 140, how many dollars equals to £5?
Answers
Answer:
$6.83= £5
Step-by-step explanation:
As £ 1=Rs 140
So, £5 = Rs 140 x 5
£5 = Rs 700 ...(i)
Now, Rs. 102.50 = $ 1
So, Rs. 1 = $ (1/102.5)
Therefore, Rs. 700 = $ (1/102.5)x 700 = $6.83
By using equation (i)
£5 = $6.83
Hence, there are $6.83= £5

What is compound interest?
What is simple interest?
Answers
Answer: Is below
Step-by-step explanation:
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.
Simple interest is a quick and easy method of calculating the interest charge on a loan. Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Answer:
See below.
Step-by-step explanation:
[tex]\boxed{\underline{\text{Compound Interest}}}[/tex]
Compound interest is earned on an investment when the interest earned for each period is added to the previous principal.
Compound interest formula:
[tex]\Longrightarrow: \sf{A=P(1+\dfrac{r}{n})^n^t}}[/tex]
A: represents the current balance or compound amount in the account.P: represents the principal (the original amount deposited).R: annual interest rate (in decimal form).N: the number of times per year that interest is compounded.T: time in years the money has been invested.[tex]\boxed{\underline{\text{Simple interest}}}[/tex]
A simple interest investment is one that earns interest only during the first period but does not earn interest thereafter.
Simple interest formula:
[tex]\Longrightarrow: \sf{I=PRT}[/tex]
I= InterestP= PrincipalR= RateT= TimeI hope this helps, let me know if you have any questions.

O {-3, -2,3}
O {-1, 2, 3}
Answers
Answer:
C, (-3, -2, 3)
Step-by-step explanation:
I literally just had this question and i got a 100. You just find what the points are, and choose the y-axis point because it's the output, like the x-axis point is the input. So for starters, we can look at the point in the upper right square corner on the grid. You would go to the left 3 times, along the x-axis, and it would be -3. Then you would go up 2 times, along the y-axis, and it would be positive 2. So the plot for that point is (-3, 2) but we want the output which is the y-axis so it would be 2. Do the same with all of the points. [you can already rule out the first 2 choices because that's giving all of the points, not just the outputs] That leaves you with the bottom 2 and only one of the choices has the positive 2 which we already found. Hence, the answer is C. Trust me, it's not hard, i didn't have to read anything, i just figured it out. And if i can, you can. You got this!

If one diagonal is 12 inches long and the other is 32 inches long, how many inches long, to the nearest hundredth of an inch, is a side of the rhombus
Answers
Answer:
17.09 inch
Step-by-step explanation:
Given that:
A rhombus with diagonals of length 12 inches and 32 inches.
To find:
The length of rhombus to the nearest hundredth of an inch.
Solution:
First of all, we need to learn about the property of a rhombus, its sides and its diagonals.
The diagonals of a rhombus intersect each other by bisecting each other and are perpendicular to each other.
And all the sides
Kindly refer to the attached image for the given dimensions.
Now, there are four right angled triangles in which we can use Pythagorean theorem to find hypotenuse which is nothing but the side of rhombus.
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow Side^{2} = 6^{2} + 16^{2}\\\Rightarrow Side^{2} = 292\\\Rightarrow Side \approx \bold{17.09\ inch}[/tex]

How do you write a slope parallel to a line?
Answers
Answer:
slope is m. Parallel means it has the same slope as the line it's parallel to. Let's say the slope of line 1 is 3, and your y intercept is 12. The equation would then be y = 3x + b and b would be 12 bc x would be 0 at y intercept making the equation become y = (0)x+b and for y to be 12, b has to be 12 in this case. So y = 3x + 12
