Find the perimeter of the figure below.
Answer:
30 ft
Step-by-step explanation:
The Pythagorean theorem can be used to find the length of the unknown side. It tells you the sum of the squares of the legs is equal to the square of the hypotenuse.
12² +a² = 13²
a² = 169 -144 = 25
a = √25 = 5
The sum of the side lengths is ...

subtract the following mixed numbers 4 3/6 - 2 1/3
Answer:
13/6 or 2 1/6
Step-by-step explanation:
In order to solve this, we have to make the denominators equal
To do that, we will need to multiply 1/3 by 2/2 which will get us 2/6
Now that we have like denominators we can convert the mixed fractions to improper fractions:
4 3/6 ---> 27/6
2 2/6 ---> 14/6
Now we can comfortably subtract the two values and simplify if needed
27/6-14/6= 13/6
So:
4 3/6 - 2 1/3 = 13/6 or 2 1/6
Find the zeros of the function g(x) = 3x^2 + 42
Answer:
There are no zeroes.
Step-by-step explanation:
If you look at the y intercept. It is 42. Furthermore, since there is an asymptote under that, the function is always increasing. Thus, there are no zeroes.

Find the value of each variable in the parallelogram.
Diagonals bisect eachother in a paralleogram
So
2u+2=5u-103u=12u=4And
v/3=6v=6(3)v=18Answer:
u = 4
v = 18
Step-by-step explanation:
The diagonals of a parallelogram bisect each other (bisect means to divide into two equal parts).
2u + 2 = 5u - 10
Add 10 to both sides:
⇒ 2u + 12 = 5u
Subtract 2u from both sides:
⇒ 12 = 3u
⇒ 3u = 12
Divide both sides by 3:
⇒ u = 4
[tex]\sf \dfrac{v}{3}=6[/tex]
Multiply both sides by 3:
⇒ v = 18

The answer for your question is C.
what is the value of x in the equation 0.3x = 0.2 - 0.2x?
Hey there!
0.3x=0.2−0.2x
Step 1: Simplify both sides of the equation.
0.3x=0.2−0.2x
0.3x=0.2+−0.2x
0.3x=−0.2x+0.2
Step 2: Add 0.2x to both sides.
0.3x+0.2x=−0.2x+0.2+0.2x
0.5x=0.2
Step 3: Divide both sides by 0.5.
0.5x/0.5=0.2/0.5
x=0.4
Therefore, x = 0.4

The number of ways is an illustration of combination
There are 1012 ways to send at least 2 and no more than 9 pledges to work
How to determine the number of waysThe given parameters are:
Pledges = 10
To send between 2 and 9 pledges
Start by calculating the number of ways to send all the pledges
[tex]n = 2^{10}[/tex]
Also,
0th pledge can be sent in 1 way1st pledge can be sent in 1 way10th pledges can be selected from any of the 10 pledgesThe number of ways the pledges can be sent is then calculated using the following complement rule

Find the measure of angle RPF
Answer: 124°
Step-by-step explanation: Notice that angles CPF and RPB are vertical <'s.
Vertical angles are two angles that share a common
endpoint and whose sides form opposite rays.
Since these angles have the same measure,
we can setup the equation 4t + 88 = 2t + 72.
Now subtract 2t from both sides and we have 2t + 88 = 72.
Now subtract 88 from both sides to get 2t = -16.
Solving from here, we find that t = -8.
Now notice that <FPB is a straight angle which
means that it measures exactly 180 degrees.
So let's substitute a 4 into the measure of angle CPF.
So we have 4(-8) + 88 or -32 + 88 which is 56°.
Since FPC and CPB are a linear pair, we know that are supplementary.
If two angles are supplementary, then the sum of their measures is 180 degrees which means we take 180 minus the measure of <CPF.
So we have 180 - 56 which is 124°.
Now since <CPB and <FPR are vertical angles
So<FPR must also measure 124°
The value of a house increased by 6%.
The house then had a value of £265000.
Work out the value of the house before the increase
+ 6% = x (1 + 6%) = x 1,06
with V = value before the increase
V x 1,06 = 265,000
so V = 265,000 : 1,06 = 250,000
The value of the house before the growth in its value was £250,000.
What do we mean by growth?We know that the value of most of the things in this world changes from time to time. When the value of an article is increased, we say that there's a growth in its value.
Growth is determined by the formula,
V = V₀(1+r), where V is the final price, V₀ is the initial price and r is the rate.
How do we solve the given question?We are told that the value of a house increased by 6%, reaching £265,000. We are asked to calculate its initial value.
Since the value has increased, we will use the formula for growth,
with V = £265,000, r = 6%, and V₀ is to be determined.
The formula is: V = V₀(1+r)
or, V₀ = V/(1+r) = 265000/(1 + 6%) = 265000/(1 + 6/100) = 265000/(106/100)
or V₀ = 265000*100/106 = 250000
∴ The initial value of the house is £250,000.
