Given points A(4,5) and B(-4,11). Find the distance AB to the nearest tenth.

If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

A bag of coins contains 2 quarters, 5 dimes, 3 nickels, and 4 pennies. If 2 coins are randomly chosen from the bag, one after the other, and not replaced, and if the total value of the chosen coins is 26 cents, what is the probability that a third coin randomly chosen from the bag will be a penny?

Answer:

B

Step-by-step explanation:

The 2 coins that have a combined value of 26 cents are a quarter and a penny. That means that 1 quarter and 1 penny must have already been removed from the bag. For this reason, the bag now contains 1 quarter, 5 dimes, 3 nickels, and 3 pennies. Therefore, the probability that a third coin randomly chosen from the bag will be a penny is

Jorge needs to ship a thin metal rod to a metalworking shop. The only boxes available for shipping are 7-inch cubes. To the nearest inch, what is the length of the longest metal rod that can be sent? 11 inches 12 inches 13 inches 14 inches

Answer:

The length of the longest metal rod that can be sent is 12 inches.

Step-by-step explanation:

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

D=\sqrt{x^{2}+x^{2}+x^{2} }

= \sqrt{3} x

Here, x is 7 inches.

So, Diagonal is = \sqrt{3} \times7

= 1.732\times7=12.12 inches.

Rounding this to nearest whole number we get 12.

So, the length of the longest metal rod that can be sent is 12 inches.

There are 10 boys and 13 girls in Ms. Kelso’s homeroom. She is going to select one boy and one girl to act as homeroom representatives for student council. How many different pairs of students could Ms. Kelso choose? A.) 10 B.) 23 C.) 130 D.) 230

The notation for this is {10 \choose 1} \cdot {13 \choose 1}.

Where you should know that {n \choose k} =  \frac{n!}{k!(n-k)!}

When choosing only one boy and one girl, it becomes simple-ish:

\frac{10!}{9!} \cdot \frac{13!}{12!} = 10 \cdot 13 = 130

So I would vote for C, hoping I didn't overlook anything...

The data shows the number of grams of fat found in 9 different health bars. 11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19 What is the IQR (interquartile range) for the data? a. 6.25 b.7 c.14.5 d.17.5

Answer:

Option A. 6.25

Step-by-step explanation:

The data shows the number of grams of fat found in different health bars is

11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19

Now we will arrange the data in ascending order

10.5, 11, 11.5, 14.5, 14.5, 17, 17, 18, 19

Middle of the numbers is 14.5 which is median of the data.

We know IQR = Median of first quartile - median of second quartile

Median of first quartile = \frac{1}{2}(11+11.5)=11.25

And median of second quartile = \frac{1}{2}(17+18)=\frac{35}{2}=17.5

Now IQR = 17.5 - 11.25 = 6.25

Therefore Option A 6.25 is the correct option.

Anna adds (8x + 12y) and (ax − 6y). If the correct answer is 5x + 6y, what is the value of a? A) −3 B) −5 C) 13 D) 3

Answer:

A) -3

Step-by-step explanation:

Given,

When (8x + 12y) is added to (ax − 6y) the answer is (5x + 6y)

(8x+12y)+(ax-6y)=(5x+6y)

8x+12y+ax-6y=5x+6y

(8+a)x+6y = 5x+6y      ( By combining like terms )

By comparing,

8+a = 5

\implies a = 5 - 8 = -3

Hence, the value of x is -3,

Option A is correct.

Triangle ABD is similar to triangle ACD. AB = 10, BC = 12, BE = 4, and CD = y. Find y.

There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

Paige borrows $700 from her parents for a new computer. She repays $100 the first month, then begins to repay her parents $75 per month. Which recursive formula models the total amount of money still owed, mc022-1.jpg?

Answer:

Option B is correct

a_n = a_{n-1}-75 ; a_1 = 600

Step-by-step explanation:

The recursive formula for the arithmetic sequence is given by:

a_n = a_{n-1}+d              .....[1]

where,

d is the common difference.

n is the number of terms.

As per the statement:

Paige borrows $700 from her parents for a new computer.

She repays $100 the first month, then begins to repay her parents $75 per month.

Now, she only has to pay back after then,  $700 - $100 = $600

then,  begins to repay her parents $75 per month.

The sequence we get;

600, 525, 450, ....

This is the arithmetic sequence.

here, a_1 = 600

and d = -75

Since,

525-600 = -75

450-525 = -75 and so on...

Substitute the given values in [1] we have;

a_n = a_{n-1}-75

Therefore, the recursive formula models the total amount of money still owed is:

a_n = a_{n-1}-75 ; a_1 = 600
