In the diagram, AABC = AWRS. What is the
perimeter of AWRS?
10 units
11 units
12 units
13 units
Answer:
12 units
Step-by-step explanation:
Both triangles have the same perimeter, so we can figure out 1 and have the answer for both.
The legs of triangle AABC are 3 and 4, so we can use the Pythagorean Theorem to figure out the other side.
3² + 4² =
9 + 16 = 25
√25 = 5
To find the perimeter, just add the three sides.
3 + 4 + 5 = 12 units
The perimeter of the triangle WRS is 12 units, Option C is correct.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
As we observe the two triangles ABC and WRS
The given triangles are similar triangles.
So if we find the perimeter of any triangle then it will be equal to other triangle.
From the triangle ABC
AB =3 units
BC =4 units
By pythagoras theorem let us find AC
AB²+BC²=AC²
3²+4²=AC²
9+16=AC²
25=AC²
Take square root on both sides
AC=5 units
To find the perimeter we need to add the three sides.
3 + 4 + 5 = 12 units
Hence, the perimeter of the triangle WRS is 12 units, Option C is correct.

Compute the probability of drawing two clubs from a standard deck of 52 cards. Round your answer to four decimal places. Answer: Compute the probability of drawing two face cards from a standard deck of 52 cards. Round your answer to four decimal places. Answer: Compute the probability of drawing two aces from a standard deck of 52 cards. Round your answer to four decimal places. Answer:
The 0.0588 = 5.88% probability of drawing two clubs from a standard deck of 52 cards.
0.0498 = 4.98% probability of drawing two faces from a standard deck of 52 cards.
0.0045 = 0.45% probability of drawing two aces from a standard deck of 52 cards
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
We know standard deck has 52 cards.
And 13 cards are for clubs.
(a).
The probability,
= number of favorable outcomes / number of outcomes
= 13 x 12 / 52 x 51
= 0.0588
0.0588 = 5.88% probability of drawing two clubs from a standard deck of 52 cards.
(b). 12 faces in a deck.
The probability,
= number of favorable outcomes / number of outcomes
= 12 x 11 / 52 x 51
= 0.04977
= 0.0498
0.0498 = 4.98% probability of drawing two faces from a standard deck of 52 cards.
(c). There are 4 aces in the deck.
The probability,
= number of favorable outcomes / number of outcomes
= 4 x 3 / 52 x 51
= 0.0045
0.0045 = 0.45% probability of drawing two aces from a standard deck of 52 cards.
Therefore, the probabilities are 0.0588, 0.0498 and 0.0045.

Bubba’s car needed work. The mechanic charged him $160 for parts plus $38 per hour for labor. If the bill totaled $300, how many hours of labor were required.
Answer:
3.7 hours
Step-by-step explanation:
h = hours in labor
t = total money
--------------------
160 + 38h = t
160 + 38h = 300
-------------------
Solve:
160 + 38h = 300
38h = 140

For the function y=x+1 what is the range if the domain is 0,1,2
Step-by-step explanation:
the domain is the interval or set of the valid values of x.
the range is the interval or set of the valid values of y.
the domain here is 0, 1 and 2.
to find the range we just have to try all 3 values of x and check the results :
x = 0
y = 0 + 1 = 1
x = 1
y = 1 + 1 = 2
x = 2
y = 2 + 1 = 3
so, the range is 1, 2, 3

if you invest $10,000 at 10% interest account compounded monthly, how much money you will have in 20 years?
Answer:
$73280.74
Step-by-step explanation:
We will use the compound interest formula to find the answer
A = P (1 + r/n)^(nt)
Where A is the total amount of money, P is the principal investment amount (how much you put in initially), R is the interest rate, N is the number of times interest is applied per period and T is the number of time periods elapsed.
$10,000 would be the principal investment amount
10% would be the interest rate
12 would be the number of times interest is applied per period (since it is paid monthly)
and 20 would be the number of time periods (as it's the number of years)
A = 10000(1+0.1/12)^(12*20)
A = 10000(7.3280736)
A = 73280.74

Step-by-step explanation:
Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs k(x)=(300+10x)(5-0.2x)
The value of [tex]x[/tex] associated to the extreme value of the quadratic equation [tex]k(x) = (300+10\cdot x)\cdot (5-0.2\cdot x)[/tex]. The extreme value is [tex]k\left(-\frac{5}{2} \right) = \frac{3025}{2}[/tex].
First, we need to expand the polynomial as follows:
[tex]k(x) = (300+10\cdot x)\cdot (5-0.2\cdot x)[/tex]
[tex]k(x) = 300\cdot (5-0.2\cdot x)+10\cdot x\cdot (5-0.2\cdot x)[/tex]
[tex]k(x) = 1500-60\cdot x +50\cdot x -2\cdot x^{2}[/tex]
[tex]k(x) = -2\cdot x^{2}-10\cdot x +1500[/tex]
[tex]-2\cdot x^{2}-10\cdot x +[1500-k(x)] = 0[/tex]
By the quadratic formula, we know that a value of [tex]x[/tex] pass through the axis of symmetry of the parabola if and only if the discriminant is zero:
[tex]-100-4\cdot (-2)\cdot [1500-k(x)] = 0[/tex]
And the value of [tex]x[/tex] is:
[tex]x = -\frac{(-10)}{2\cdot (-2)}[/tex]
[tex]x = -\frac{5}{2}[/tex]
And the extreme value is:
[tex]k\left(-\frac{5}{2} \right) = -2\cdot \left(-\frac{5}{2} \right)^{2}-10\cdot \left(-\frac{5}{2} \right) + 1500[/tex]
[tex]k\left(-\frac{5}{2} \right) = \frac{3025}{2}[/tex]
The value of [tex]x[/tex] associated to the extreme value of the quadratic equation [tex]k(x) = (300+10\cdot x)\cdot (5-0.2\cdot x)[/tex]. The extreme value is [tex]k\left(-\frac{5}{2} \right) = \frac{3025}{2}[/tex].
