WILL MARK BRAINLIEST!! Complete the statements to find the measurements of ∠a and ∠b .
Answer:
angles b and a both equal 60 degrees
Step-by-step explanation:
a and b are both equal to 60 degrees. A flat angle is 180 and you have the one that’s 120 so that one is 60 and then the last side must be 60 as well because when you add them then subtract it from 180 you get 60

Explicit formula for the sequence -3,-14,-25,-36
ANSWER
[tex]a_{n}=a_{n-1} - 11 \: \: ,a_1 = - 3[/tex]
EXPLANATION
The given sequence is
[tex]-3,-14,-25,-36,...[/tex]
The first term of the sequence is
[tex]a_1=-3[/tex]
The common difference is
[tex]d = - 14 - - 3[/tex]
[tex]d = - 11[/tex]
The recursive formula is
[tex]a_{n}=a_{n-1} - 11 \: \: ,a_1 = - 3[/tex]
Answer:
aₙ = aₙ₋₁ -11
Step-by-step explanation:
We have given the sequence:
-3,-14,-25,-36
We have to find the explicit formula.
The first term in this sequence is:
a₁ = -3
The common difference is:
a₂-a₁= -14-(-3) = -11
a₃-a₂ = -25-(-14) = -11
a₄-a₃ = -36-(-25)= -11
Common difference d = -11
The general formula is :
aₙ = aₙ₋₁ +d
Here d = -11 so,
aₙ = aₙ₋₁ -11 is the explicit formula.
Simplify the expression square root of 6 times the square root of 33 plus 7
Answer:
3√(22) + 7
Step-by-step explanation:
The way this is worded can be interpreted two different ways so just to cover the bases, I'll do both. I'm confident they are asking for way 1 though because it wants you to simplify the expression, not evaluate. Way 2 gives you a solution rather than an exact equation.
Number 1
√(6) x √(33) + 7
= √(6 x 33) + 7
= √(198) + 7
= √(9 x 22) + 7
= 3√(22) + 7
Number 2
√(6) x √(33 + 7)
= √(6) x √(40)
= √(6) x (4√(10))
= 4√(60)
= 8√(15)
The simplified expression for [tex]\sqrt{6} \times \sqrt{33} + 7[/tex] is [tex]3\sqrt{22} + 7[/tex]
To simplify square root of 6 times the square root of 33 plus 7 we need to first write it mathematically. We get:
[tex]\sqrt6 \times \sqrt{33}+7[/tex]
Using BODMAS, we first multiply the roots. This will give us:
[tex]\sqrt{6} \times \sqrt{33} + 7 = \sqrt{6 \times 33} +7[/tex]
Now we need to expand the digits in square by expressing them as a product of their prime factors so that common pairs can be taken out of the root. This can be done as follows:
[tex]\sqrt{6 \times 33} +7 = \sqrt{(3 \times 2)\times (3\times11)} +7[/tex]
We can see that there are two pairs of 3. Thus we extract 3 times 3 as it is a perfect square for 9 and we get:
[tex]3\sqrt{( 2\times 11)} +7 = 3\sqrt{2}+7[/tex]
Thus, the simplified expression for [tex]\sqrt{6} \times \sqrt{33} + 7[/tex] is [tex]3\sqrt{22} + 7[/tex]
according to the graph of F(x), which of the statements below are true? check all that apply
Answer:
B, E and F
Step-by-step explanation:
This graph is a log which has an asymptote. This means the function does not cross it and does not have in its domain certain numbers. The asymptote is at -2. This means the domain is greater than -2.
The range is the y-values. With no restrictions here, the function includes all numbers.
This means B, E, and F are true.

What is the likelihood that a fair coin will land heads or tails?
which would it be?
0.5
1
0
0.25
Answer:
I believe it is 0.5
Step-by-step explanation:
If you flip a normal coin (called a “fair” coin in probability parlance), you normally have no way to predict whether it will come up heads or tails. Both outcomes are equally likely. There is one bit of uncertainty; the probability of a head, written p(h), is 0.5 and the probability of a tail (p(t)) is 0.5. The sum of the probabilities of all the possible outcomes adds up to 1.0, the number of bits of uncertainty we had about the outcome before the flip. Since exactly one of the four outcomes has to happen, the sum of the probabilities for the four possibilities has to be 1.0. To relate this to information theory, this is like saying there is one bit of uncertainty about which of the four outcomes will happen before each pair of coin flips. And since each combination is equally likely, the probability of each outcome is 1/4 = 0.25. Assuming the coin is fair (has the same probability of heads and tails), the chance of guessing correctly is 50%, so you'd expect half the guesses to be correct and half to be wrong. So, if we ask the subject to guess heads or tails for each of 100 coin flips, we'd expect about 50 of the guesses to be correct. Suppose a new subject walks into the lab and manages to guess heads or tails correctly for 60 out of 100 tosses. Evidence of precognition, or perhaps the subject's possessing a telekinetic power which causes the coin to land with the guessed face up? Well,…no. In all likelihood, we've observed nothing more than good luck. The probability of 60 correct guesses out of 100 is about 2.8%, which means that if we do a large number of experiments flipping 100 coins, about every 35 experiments we can expect a score of 60 or better, purely due to chance.
Answer:
The correct answer option is 0.5.
Step-by-step explanation:
If we have a fair coin then it means that it has a 50 % chance of landing heads up and a 50% chance of landing tails up.
A fair coin is one which has two sides: head and tail.
Since their are two sides to each fair coin, so the probability of landing for each of the side should add up to 1 (which is the total probability).
Therefore, likelihood that a fair coin will land heads or tails is 0.5.
A point located at (3, -2) is translated right 3 units and down 4 units. What are the coordinates of the image? (0, -2) (6, -6) (6, 2) (0, -6)
Answer:
(6,-6)
Step-by-step explanation:
Because if you move to the right 3 units you add 3 to the x-axis number or in this case 3, so 3+3=6, and if you move down 4 units its the same as subtracting 4 from the y-axis number or in this case -2 so, -2-4=-6. Which gives you (6,-6).

Solve the inequality by using inverse operations.

w > 9
Like solving equations, inequalities should be solved using inverse operations. However, unlike equations, when you divide or multiply by a negative the sign changes.

full-time job usually means you will work how many hours per week? A. 20 B. 35 C. 40 D. 55 Please select the best answer from the choices provided A B C D
Answer:
C. 40 or B. 35
Step-by-step explanation:
Full time jobs are typically jobs that vary from 35-40 hours a week.
Hope this helps :)
Answer:
C) 40 hours
Step-by-step explanation:
Usually, a full-time job employee works 8 hours per day. There are 7 days in a week where most of employees work 5 days a week, remaining 2 days week off.
Therefore, the number of hours per week = 5 days * 8 hours per day
= 40 hours
Hence, the answer is C) 40

Will give brainliest and all my points
Answer:
Angelo : 4
Luis : 2.9
Xavier : 3.8
Angel : 3.4
Step-by-step explanation:
As mentioned in the question, tip is 20% of the bill. Therefore, to calculate the tip each person should leave can be calculated by sum of all items and taking 20% of of the amount
1) Angelo = 2 + 8 + 10 = 20
total tip = 20% of 20 = 20/100 * 20 = 4
2) Luis = 1.50 + 8 + 5 = 14.5
total tip = 20% of 14.5 = 20/100 * 14.5 = 2.9
1) Xavier = 2 + 10 + 7 = 19
total tip = 20% of 19 = 20/100 * 19 = 3.8
1) Angel = 2 + 5 + 10 = 17
total tip = 20% of 17 = 20/100 * 17 = 3.4
Answer:
Angelo : 4
Luis : 2.9
Xavier : 3.8

The function f(x) is shown in this graph
Answer:
The correct statement is:
The slope of f(x) is same as the slope of g(x)Step-by-step explanation:
We see that the graph of the function f(x) is a line that passes through (0,2) and (1,-1)Hence, the equation of the function f(x) is calculated by a two-point formula as:
[tex]y-2=\dfrac{-1-2}{1-0}\times (x-0)\\\\y-2=\dfrac{-3}{1}\times x\\\\y-2=-3x\\\\y=-3x+2[/tex]
( On comparing the equation of f(x) with slope intercept form.
i.e. y=mx+c
where m is the slope and c is the y-intercept)
We get slope of f(x)= -3
and y-intercept= 2
The function g(x) is given by:[tex]g(x)=-3x-6[/tex]
Hence, slope of g(x) = -3
and y-intercept= -6
Hence, we get that the slope of f(x) and g(x) is same.
