The perimeter of a triangle is 65 meters. The second side is 5 meters less than the first side.The third side is 7 meters more than the first side. What is the length of each side?
Answer:
The length of each side of triangle is:
First side of triangle = 21 inches
Second side of triangle = 16 inches
Third side of triangle = 28 inches
Step-by-step explanation:
Perimeter of triangle = 65 meters
Let
First side of triangle = x
Second side of triangle = x-5 (The second side is 5 meters less than the first side.)
Third side of triangle = x+7 (The third side is 7 meters more than the first side.)
We need to find length of each side.
The formula used is:
[tex]\mathbf{Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle}[/tex]
Putting values and finding value of x
[tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\65=x+x-5+x+7\\65=3x+2\\Switching\:sides\\3x+2=65\\Subtracting\:2\:from\:both\:sides\\3x+2-2=65-2\\3x=65-2\\3x=63\\Divide\:both\:sides\:by\:x\\\frac{3x}{3}=\frac{63}{3}\\x=21[/tex]
So, We get value of x = 21
Now, finding the length of each side of triangle:
First side of triangle = x = 21
Second side of triangle = x-5 =21-5 =16
Third side of triangle = x+7 = 21+ 7 = 28
The length of each side of triangle is:
First side of triangle = 21 inches
Second side of triangle = 16 inches
Third side of triangle = 28 inches
a savings account earns 8% interest each year, compounded quarterly (4 times a year). If a person invests $100 and makes no further deposits or withdrawals, what is the balance in the account after 3 years?
===========================================
Work Shown:
The given values are
P = 100 = amount deposited (principal)r = 0.08 = decimal form of the annual interest raten = 4 = compounding frequencyt = 3 = number of yearsWhich means,
A = P*(1+r/n)^(n*t) .... compound interest formula
A = 100*(1+0.08/4)^(4*3) .... plug in given values
A = 126.824179456254 ..... value is approximate
A = 126.82 ...... round to the nearest cent
The balance of the account after three years is $126.82
Answer:
124 dollars
Step-by-step explanation:
.08 times 100 equals 8
eight times three is twenty four
that is the simplest answer. if the question had any further interests it might of been 126 or even 125.97

Answer:
226.08 in^2
Step-by-step explanation:
The formula for area of a circle is pi*r^2
3^2 = 9
9*3.14 = 28.26
The formula for volume of a cylinder is surface area times height

what is an equation of the line that passes through the points (-2,1) and (-8,4)
Answer:
y = -1/2 x
Step-by-step explanation:
slope = Δy / Δx
= 4 - 1 / -8 - (-2)
= 3 / -6
m = - 1/2
y = mx + b
1 = (-1/2)(-2) + b
1 = 1 + b
b = 0
eqn of the line : y = -1/2 x

What is the product of (3a + 2)(4a2 – 2a + 9)? 12a3 − 2a + 18 12a3 + 6a + 9 12a3 − 6a2 + 23a + 18 12a3 + 2a2 + 23a + 18
Answer:
12a3 + 2a2 + 23a + 18
Step-by-step explanation:
Vertical multiplication works well when you have a binomial times a trinomial.
Multiply 2 times the trinomial and get 8a2 - 4a + 18 then multiply 3a times the trinomial to get 12a3. -6a2 + 27a
Then combine like terms.
The product of the givens expressions is 12a³ + 2a² + 23a + 18.
Product of the given expressionsThe product of the givens expressions is obtained by multiplying all the variables in the bracket as shown below.
(3a + 2)(4a² – 2a + 9) = 3a(4a² – 2a + 9) + 2(4a² – 2a + 9)
= 12a³ - 6a² + 27a + 8a² - 4a + 18
simplify by collecting similar terms together
= 12a³ + 2a² + 23a + 18
Thus, the product of the givens expressions is 12a³ + 2a² + 23a + 18.

Answer:
(-7)2 = -14
Step-by-step explanation:
The parenthesis basically mean "multiply". So, this is a simple equation meaning -7 x 2. And remember, anytime we multiply a positive by a negative, you get a negative. So, simply multiply 7 x 2 = 14 and add a negative sign to make the solution true. So, -7 x 2 or (-7)2 = -14
Hope this helps! If you have any additional questions, please don't hesitate to ask me or your teacher to be sure you master the subject. Also thank you for the generous points!! Stay safe and please mark brainliest!!
Answer:
-14
Step-by-step explanation:
just act as if -7 were positive then you know 7x2 = 14 cause' "()" means multiplication.
last, since 7 was negative in the first place then you turn your product back to a negative and you get -14

3) Substitution Property 4) Transitive Property
Answer:
2) Subtraction Property of Equality Properties

Step 1: Define
4m + 1 = 7 → 4m = 6
Step 2: Identify
We see that we subtracted on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

Answer:
The change should Sara receive from the $10 bill is $3.56.
Step-by-step explanation:
Given:
The table shows the prices of some breakfast items at a restaurant.
Item Price
One egg $1.69
Slice of bacon $1.49
Glass of orange juice $1.09
Sara ordered 2 eggs, a slice of bacon, and a glass of orange juice for breakfast.
The sales tax for the order was $0.48.
She paid for her breakfast with a $10 bill.
Now, to find the change should Sara receive from the $10 bill.
Bill for the Sara's breakfast:
2 eggs = 2 x 1.69 = 3.38
A slice of bacon = $1.49.
A glass of orange = $1.09.
The sales tax = $0.48.
Total bill = 3.38 + 1.49 + 1.09 + 0.48 = 6.44
Sara paid for the breakfast bill = $10.
Now, to get the change Sara should receive we subtract the amount of bill from the money Sara paid for the bill:
sara paid for the breakfast bill - total bill
=10 - 6.44
=3.56
Therefore, the change should Sara receive from the $10 bill is $3.56.
hope it helps!
What is 1/3 + 4/9 and how to solve
Answer:
7/9
Step-by-step explanation:
To add fractions, you have to have like denominators. First find the LCM (Least Common Multiple) of both denominators. That is 9. The second fraction already has a denominator of 9, so leave it as is. The first fraction doesn't so what will happen is you will be converting it into a fraction with a denominator of 9. Multiply the denominator by 3 to get 9. Then multiply the top by 3 because whatever you do to the bottom you do the top. You will then get 3/9. 3/9+4/9 is equal to 7/9 because you just add the numerators, but keep the denominators the same.

what is the sum of three consecutive even numbers is 30?
Answer:
here:
you can make an equation
x + ( x + 2) + (x + 4) = 30
then by combining like items you get
3x + 6 = 30
then solve
3x = 30 - 6 ; then 3x = 24 , and x = 8
so the three numbers are 8 ; 10 and 12.
Can someone help pls?
Answer:
Step-by-step explanation:
Let the original width be x
Then the original length = x + 11
Area = x * (x + 11)
If you decrease each side by 7 you get
Area 1 = (x - 7)(x + 4)
So area - area1 =
x (x + 11) -98 = (x - 7)(x + 4) Remove the brackets
x^2 + 11x - 98 = x^2 - 7x + 4x - 28 Combine the like terms
x^2 + 11x - 98 = x^2 - 3x - 28 Add 98 to both sides
x^2 + 11x = x^2 - 3x + 70 Cancel the x^2
11x = -3x + 70 Add 3x to both sides
14x = 70 Divide by 14
x = 70 / 14
x = 5
=====================
Original conditions
Answer width = 5
Length = 16
