Answer 1

Answer:

Answer: x= 45 degrees

Step-by-step explanation: The angle of a square is 90 degrees and it already tell you the other side is 45 degree so 90 - 45 = 45. So that means the answer is 45 degrees.

Answer 2

Answer:

Since the sum of all the angles of any triangle is 180 degrees, just add 90 and 45 (the answer being 135), then subtract 135 from 180 (answer is 45).

Therefore, the missing answer is 45 degrees.

$2,642.77
$2,715.77

Answer:

The new balance of her saving account is $ 2252.79

Step-by-step explanation:

Given : Ellen Saver went to her bank. She had a balance of $2,447.67 in her savings account. She withdrew $231.49 and the teller credited her account with $36.61.

We have to determine the new account balance.

Since inital balance is $ 2,447.67

ans she withdraw $ 231.49 that is taken ouu so we subtract from inital balance.

thus, balance after withdraw is (2447.67 - 231.49) = $ 2216.18

Now, the teller credited the account with $ 36.61 that is $ 36.61 is added to the account.

So, new balance after credit $ 36.61 is $(2216.18 + 36.61) = $ 2252.79

Thus, the new balance of her saving account is $ 2252.79

Given:

Beginning Balance: 2,447.67
Less: Withdrawal 231.49
Total 2,216.18
Add: Credit to acct 36.61
Ending Balance 2,252.79

The new balance is $2,252.79

Given:

The figure of a right angle triangle.

A line segment intersect the two sides and parallel to third side of the triangle

To find:

The value of x.

Solution:

According to basic proportionality theorem, if a line segment intersect the two sides and parallel to third side of the triangle, then it divides the two sides proportionally.

Using basic proportionality theorem, we get

$(8)/(20-8)=(6)/(x)$

$(8)/(12)=(6)/(x)$

$(2)/(3)=(6)/(x)$

On cross multiplication, we get

$2* x=6* 3$

$2x=18$

$x=(18)/(2)$

$x=9$

Therefore, the value of x is 9.

A recursive rule for a geometric sequence is a1=3;an=1/2(an−1) What is an explicit rule for this sequence?

Answers

Answer:The explicit rule for this sequence:

$a_n=a_1(r)^(n-1)=3((1)/(2))^(n-1)$

Step-by-step explanation:

$a_1=3$

$a_n=(1)/(2)a_(n-1)$

Where $a_n$ = n'th term in a sequence

$a_2=(1)/(2)a_((2-1))=(1)/(2)a_1=(1)/(2)* 3=(3)/(2)$

The value 'r' is geometric mean is given as:

r = common ratio

$r=(a_2)/(a_1)=((3)/(2))/(3)=(1)/(2)$

The explicit rule for this sequence:

$a_n=a_1(r)^(n-1)=3((1)/(2))^(n-1)$

A recursive rule for a geometric sequence is a1=3;an=1/2(an−1)
explicit rule
an = (3)(1/2 )^n−1

The answer is D. Because all that you do to get a reciprocal is flip the fraction and 1 isn't relevant when it's on the bottom so you drop it and it's just 5.

Suppose a jar contains 9 red marbles and 24 blue marbles. If you reach in the jar and pull out 2 marbles at random, find the probability that both are red. Round your answer to 4 decimal places.

Answers

Answer: 0.0727

Step-by-step explanation:

We can use the concept of probability:

In this case, we have 9 red marbles and 24 blue marbles, so the total number of marbles is 9 + 24 = 33.

Since there are 9 red marbles out of 33 total marbles, the probability of drawing a red marble on the first draw is 9/33.

There will be 8 red marbles left out of the remaining 32 marbles in the jar. So, the probability of drawing a second red marble after the first red marble is 8/32.

To find the probability of both marbles being red, we multiply the probabilities of the fractions together. (9/33) * (8/32).

Now let's round the answer to 4 decimal places!

(9/33) * (8/32) ≈ 0.0727

Therefore, the probability that both marbles drawn are red would be 0.0727. Sorry if it's nonsense, I'm just an average 6th Grader : D

Final answer:

The probability of pulling out 2 red marbles from the jar is approximately 0.0727.

Explanation:

To find the probability of pulling out two red marbles from the jar, we need to calculate the probability of pulling out a red marble on the first draw and then a red marble on the second draw.

The probability of pulling out a red marble on the first draw is 9/33, since there are 9 red marbles out of a total of 33 marbles. After the first marble is removed, there are now 8 red marbles left out of a total of 32 marbles. So, the probability of pulling out a red marble on the second draw is 8/32.

To find the probability of both events happening, we multiply the probabilities together: (9/33) * (8/32) = 0.0727 (rounded to 4 decimal places).
