What Is The Length Of BC In The Right Triangle Below?

Answers

Answer 1

Answer:

A. 122

Step-by-step explanation:

in right-angle triangle,

AB² + AC² = BC²

22²+120² = BC²

2²×11² + 2⁶×5²×3²= 2²(121+16×25×9)

4(121+3600) = 14884

BC=√14884 = 122

Amy graphed a point to represent the absolute value of a number on a number line. If the original number is less than −10, describe all the possible values for the point Amy graphed on the number line.

Answers

Answer:

x>= 11 or x>10

Step-by-step explanation:

Absolute value can be used to represent the positive counterpart of a negative number. In this case, we are asked to find a number that is less than -10, meaning from -11 to negative infinity. Since we are asked to take absolute value, we would take |-11| which equals 11, and |-∞| = ∞.

So Amy graphed a value on the number line that is greater than or equal to 11, or any value greater than 10.

*Infinity is not a real number, it represents the largest number possible, which doesn't exist since numbers can continue on forever, so it can be disregarded.*

x = 180-147

x =33

Answer: 33

Step-by-step explanation:

A triangle is equal to 180 degrees. So you add 124 and 23 to get 147. You would then subtract 180-147=33 and then you have your answer. Hope this helps!

Pre college which is correct

Answers

Answer:

x = 7 and y = -8      ordered pair is (7, -8)

Step-by-step explanation:

0.1x + 0.3y = - 1.7

0.3x - 0.5y = 6.1

Solving the first equation for x    0.1x = -0.3y - 1.7

                                                     0.1x/0.1 = -0.3y/0.1 - 1.7/0.1

                                                          x = -3y - 17

Substitute into the second equation.

0.3(-3y - 17) - 0.5y = 6.1

 -0.9y - 5.1 - 0.5y = 6.1

-1.4y - 5.1 = 6.1

-1.4y = 5.1 + 6.1

-1.4y = 11.2

     y = 11.2/-1.4

     y = -8

     Substitute y into the first  equation and solve for x

               x = -3y - 17

                x = -3(-8) - 17

                x = 24 - 17

                x = 7

Find the rate if a principal of $1,800 earned $378 interest in 6 years

Answers

Answer:

Interest rate (r ) = 0.035 or 3.5%

Step-by-step explanation:

Given the principal amount of $1,800, and an interest payment of $378 earned in 6 years:

Use the simple interest formula and algebraically solve for variable, interest rate, r :

I  =  P × r × t

Where:

I = interest payment = $378

P = principal amount = $1,800

t = time (in years) = 6

r = interest rate

Divide both sides by P × t to isolate r :

[tex]\displaytext\sf{\frac{I}{P\:\times\:t}\:=\:\frac{P\:\times\:r\:\times\:t}{P\:\times\:t}}[/tex]

[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{I}{P\:\times\:t}}[/tex]

Substitute the given values into the formula for the interest rate:

[tex]\displaytext\sf{interest\:rate\:(r)\:=\:\frac{378}{1800\:\times\:6}\:=\:\frac{378}{10800}}[/tex]

Interest rate (r ) = 0.035 or 3.5%

Therefore, the interest rate is 3.5%.

Answers

g(x) = 2x^2

for g(- 4), you just plug in - 4 for x

g(- 4) = 2(- 4)^2

g(- 4) = 2(16)

g(- 4) = 32

Answer:

g(-4) = 32

Step-by-step explanation:

Given the quadratic function, g(x) = 2x², finding the output value given g(-4) involves substituting the value of the input, x = -4, into the function.

Solution:

g(x) = 2x²

g(-4) = 2(-4)² = 2(-4)(-4)

g(-4) = 2(16)  

g(-4) = 32

Therefore, g(-4) = 32.

. You intend to draw a random sample of 36 items from this population.

Find the probability that the mean of this sample is less than 105.4.

Answers

The probability that the mean of this sample is less than 105.4 is 14.46%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\x=raw\ score, \sigma=standard\ deviation, \mu=mean,n\ is\ sample\ mean\\\\\\Given\ that\ \sigma=45,\mu=124.5,n\ =36,hence:\\\\For\ x<105.4:\\\\z=\frac{105.4-124.9}{45/\sqrt{36} }=-1.06[/tex]

From the normal distribution table, P(x < 105.4) = P(z < -1.06) = 0.1446 = 14.46%

The probability that the mean of this sample is less than 105.4 is 14.46%
