Find the value of x and y
I don’t know how
Answer:
x = 2√30, y = 2√21
Step-by-step explanation:
You can create the following equations:
(1) from the left triangle with sides x, y and 6:
y² + 6² = x²
(2) from the right triangle with sides y, 14 and... lets call it z:
y² + 14² = z²
(3) from the big triangle:
x² + z² = 20²
(4) Combine (2) and (3) to eliminate z:
x² + y² + 14² = 20²
combine (1) and (4) to eliminate x:
y² + 6² + y² + 14² = 20²
simplify
2y² = 20² - 6² - 14² = 168
y² = 84
y = √84 = 2√21
x² = y² + 6² = 84 + 36 = 120
x = √120 = 2√30

What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is 3k+5l+6l+2k.
Group like terms and simplify, we get
(3k+2k)+(5l+6l)
= 5k+11l

A: $571.89
B: $588.49
C: $722.96
D: $726.03
Answer:
B.
Step-by-step explanation:
Answer: B. $588.49
Step-by-step explanation:
Arlene's ending balance on 10/3 is $604.51
On 10/4 she makes a deposit (+) of $412.45
On 10/5 she makes an ATM withdrawal (-) of $80.00
And on 10/9 a check (-) of $348.47
$604.51+ $412.45- $80.00- $348.47= $588.49
SAT/ACT If n is divisible by 2,5, and 14, which of
the following is also divisible by these numbers?
A n+7
D n + 20
B n + 10
E n + 70
C n + 14
Answer:
Option E : n+70 is the correct answer.
Step-by-step explanation:
Given that:
n is divisible by 2,5 and 14.
We have to add a number to n which will make the resulting number also a divisible of 2, 5 and 14.
Therefore,
We will add a number that is multiple of 2,5 and 14
Here,
7 is not a multiple of 2,5 and 14.
20 and 10 are multiples of 2 and 5 but not 14.
70 is a multiple of 2,5 and 14.
14 is a multiple of 2 and 14 but not 5.
Hence,
Option E : n+70 is the correct answer.
On a highway, a random sample is taken of the speed, in mph, of 50 cars. A mean speed of 61.8 mph is calculated with a margin of error of +2.3 for a 95% confidence interval What is the interval estimate of the population mean?
A) 58.7 <h<64.9
B)59.5<h<61.8
C)59.5<h<64.1
D)61.8<h<64.1
The interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.
What is margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
The interval estimate of the population mean can be found out using the following formula:
[tex]\overline X\pm MOE[/tex]
Here, [tex]\overline X[/tex] is the average mean, and the MOE is the margin of error.
On a highway, a random sample is taken of the speed, in mph, of 50 cars.
A mean speed is 61.8 mphThe margin of error is +2.3 The confidence interval is 95%Put the values in the above formula as,
[tex]61.8\pm 2.3\\59.5,641[/tex]
Thus, the interval estimate of the population mean
[tex]59.5 < h < 61.8[/tex]
Hence, the interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.

Elaine opened a savings account with a deposit of $1000. The interest on her account is compounded each year at a rate of 2%. Elaine will not make any additional deposits to or withdrawals from her account. What will be the balance in Elaine's account at the end of 3 years? Round your answer to the nearest whole dollar.
Answer:
$1,061.21
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value (PV) = $1,000
Rate of interest compounded yearly (r) = 2%
Time period (n) = 3
So, we can calculate the future value (FV) by using following formula,
Future Value = PV(1 + r)^n
By putting the value, we get
FV = $1,000 ( 1 + 0.02)^3
= $1,000 ( 1.02)^3
= $1,000 ( 1.061208)
= $1,061.21

The value of the internal angle m from the heptagon is given by the equation m = 141°.
What is the sum of a polygon's internal angles?The formula returns the sum of the internal angles of a polygon.
The sum of the internal angles of an n-sided polygon is n = 180° (n - 2), where n is the number of sides = angle in degrees
Given the data,
Let's call the polygon a heptagon.
The polygon has n sides, which equals 7 sides.
Now, n = 180 is the sum of the interior angles of a polygon with n sides ( n - 2 )
7θ = 180 ( 7 - 2 )
7θ = 180 ( 5 )
When we simplify the equation, we obtain 7 = 900°.
A = 900° denotes the sum of the internal angles of the polygon.
And , the value of A = 120° + m° + 148° + 90° + 142° + 130° + 129°
900° = m + 759°
Subtracting 759° on both sides of the equation , we get
m = 141°
Hence , the interior angle ∠B = 141°
