Answer:
JL = √38.
a = 1 and b = 38.
Step-by-step explanation:
Using Pythagoras:
(JL)^2 = (√8)^2 + (√30)^2
(JL)^2 = 8 + 30 = 38.

What is the value of x? NEDD HELP ASP
A x=15
B x=30
C x=37.5
D x=52.5
Answer:
The value of x is 15 .
Option (A) is correct.
Step-by-step explanation:
As given
∠1 and ∠2 are complementary.
i.e the sum of ∠1 and ∠2 is 90° .
Thus
∠1 + ∠2 = 90°
x° + (3x+30)° = 90°
x + 3x + 30 = 90
4x = 90-30
4x = 60
x = \frac{60}{4}x=
4
60
x = 15
Therefore the value of x is 15 .
Option (A) is correct.
Answer:
A. x=15
Step-by-step explanation:
To solve this problem, we can combine like terms.
3x + (1)x are like terms.
3x + (1)x = 4x.
Since 3x and (1)x are the only pair of like terms, we are done with this step.
Complementary angles have a sum of 90°.
4x + 30 = 90.
Next, we subtract 30 from 90.
90 - 30 = 60.
Then, we divide 60 from 4.
60 / 4 = 15.
15 is the final answer.
Therefore, the value of x is 15.

You save $1400 from a summer job. You decide to put it into an account that earns simple annual interest. After 9 months, your balance is $1421. Find the annual interest rate.
Answer:
2%
Step-by-step explanation:
Calculate annual interest amount first:
annual interest x 9/12=21
Annual interest =21x12/9
annual interest amount=$28
calculate annual interest rate
1400 x interest rate = annual interest
$1400 x interest rate = $28
interest rate =$28/1400
interest rate=.02 or 2%

Step-by-step explanation:
Initial co-ordinate of p = ( 2, -2)
Rule for rotation 180° about the origin
(x,y) ----> ( -x , -y )
Meaning of the rule: To find the coordinates of a point that was rotated 180° about the origin all we have to do is add negative signs in front of the x and y values of the coordinates. THE NUMBER STAYS THE SAME. THE ONLY THING THAT CHANGES IS THE SIGN
* add - to the coordinates *
- ( 2 , -2 )
-1 * 2 = -2
-1 * -2 = 2
we end up with ( -2, 2 )
Hence the answer is B
For this one a rectangle was dilated and we have to find the scale factor and the new width.
We are given the pre image width (3) and length (4) and the new image length (12)
We can find the scale factor by dividing the new image length by the pre image length ( Note that you have to use corresponding sides. Like pre image height over new image height or pre image length over new image length. etc. )
So scale factor = 12 / 4 or 3
Now to find the new image width
We can do this by multiplying the pre image width (3) by the scale factor (3)
So new image width = 3 * 3
3 * 3 = 9
Hence the width of the enlarged print is C 9 inches
For this one we need to find x using angle rules
The angles shown are supplementary angles meaning that the sum of the two angles is 180
That being said we can create an equation to solve for x
180 = 64 + 4x + 16
Now we just solve using basic algebra
step 1 combine like terms
64 + 16 = 80
now we have 180 = 4x + 80
step 2 subtract 80 from each side
80 - 80 cancels out
180 - 80 = 100
now we have 100 = 4x
step 3 divide each side by 4
100/4 = 25
4x/4=x
we're left with x = 25

Joe, Marty, and Sally all decide to buy a new car for $15,000. Each one decides to pay for their car in a different way. Compare each of their stories and decide who you think made the best decision when they bought their car.
Joe decided he wanted to pay cash for his car, so he saves $1,000 per month until he has enough money in the bank to buy the car. How long will it be before Joe can buy his car?
Answer: 15 months
Step-by-step explanation: bc if you multiply 15 times the amount he is saving a month which is $1,000. you multiply them two together and get 15,000. (sorry if i over explained it)

Step-by-step explanation:
Volume of a triangular pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]
= 360 cm³
2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
= [tex]\frac{1}{2}(8)(5)[/tex]
= 20 cm²
Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]
= 80 cm³
5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here, r = radius of the circular base
h = Height of the cone
Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]
= [tex]\frac{16\pi }{3}[/tex]
= 16.76 cm³

The number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.
What is the Permutations?Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.
The given digits are 4, 6 and 8.
We know that, P(n, r)= n!/(n-r)!
Here, n=3 and r=2
Now, 3!/(3-2)!
= 3×2
= 6
Using C(n, r)= n!/r!(n-r)!
Now, 3!/2!(3-2)!
= 3
So, 6×3
= 18
Therefore, the number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Hey guys. So I'm doing a basic program for a battle game in Javascript, and I've having trouble on this one question. (subtraction)
If I have one number like 20, then 3 numbers such as 2, 4 and 7, I could easily find out which number in those 3 i subtracted by. For example if I had 18 as the answer, then I could do 20 - 18 and get 2 from the 3 numbers.
But how do I do that twice? or three or more after that one time? how would I know which one I picked after? (after the number is used once, it can still be used forever on, it's always random)

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has two opportunities for a two-point conversion. He misses the first attempt 50% of the time. When he misses the first attempt, he misses the second attempt 15% of the time. What is the probability of missing both two-point conversion attempts?
Answer:
P = 0.075 P = 7.5%
Step-by-step explanation:
We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.
We know for a fact that the probability that the quarterback fails the first attempt is:
p(1) = 0.5
and we know that the probability that the quarterback fails the second attempt after failing the first is:
p(2/1) = 0.15
Then the probability of failure of both attempts is:
P(2/1) = p(1 and 2) / p(1)
p(1 and 2) = P(1) * P(1/2)
p(1 and 2) = 0.5 * 0.15
and that is
p(1 and 2) = 0.075
