Four friends are told that the average (mean) of their grades for their favorite class is 83.75%.
Kevin got 94%, Elizabeth got 78%, and Katherine got 83%.
Tyler's grade was not revealed. What's Tylers grade?
Answer:
Tyler got 80%.
Step-by-step explanation:
Represent Tyler's average by t.
Then .94 + .78 + .83 + t
-------------------------- = 83.75%
4
Multiplying both sides by 4, we get 2.55 + t = 3.35
so that t = 3.35 - 2.55 = 0.80
Tyler got 80%.
solve 5/8 + 3/4 divided by -2/3 - 5/

Answer:
176 cm^2
Step-by-step explanation:
Area of a triangle = 1/2(b)(h)
*b means base and h means height*
Since there are four separate triangles here, we have to find the area for each and add each area together.
1/2(8)(16)
1/2(128)
64
We can multiple 64 by 2, because there are two triangles of this same size in the kite.
64(2) = 128
1/2(8)(6)
1/2(48)
24
We can also multiply 24 by two since the kite includes two triangles of this same size.
24(2) = 48
48 + 128 =

Refer to the table shown. If the pattern continues what algebraic expression can be used to find the plants height for any month? What will be the plants height at 12 months?
Answer:Answer is 36 inches high.
Step-by-step explanation:
Each term is 3 times the number of months. So, the
expression is 3n.
3 3(12) n
Replace n with 12.
36
At the end of 12 months, the plant will be 36 inches high.

Gordon types 3,136 words in 49 minutes. Find the unit rate.
Answer: Gordon types 64 words per minute.
Step-by-step explanation: Because Gordon is typing 3,136 words in 49 minutes, you would divide the words by the minutes. 3,136 ÷ 49 = 64. So, the units would be 64 words per minute.

1. I roll a standard six-sided die 6 times in a row. What is the probability that the numbers alternate between odd and even?
2. We draw a card from a standard deck. What is the probability that it is a Jack, Queen, King, or it is red?
3. A student applies to four colleges, all of which decide admissions through random lotteries. The probability of admissions to each college is given in the table below. If the student applies to all four of these colleges, what is the probability that he is admitted to at least one of them? Express your answer as a fraction in simplest form.
College 1: 1/7
College 2: 1/8
College 3: 1/9
College 4: 1/10

Find the area of this circle. Use 3.14 for pie .
Answer:
8820.26 m^2
Step-by-step explanation:
The diameter is 106
The radius is 1/2 of the diameter
1/2 ( 106) = 53
The area of a circle is
A = pi r^2
= (3.14) ( 53)^2
= 8820.26 m^2
32 ÷ 4 x (16 x 1/2) -2
32 ÷ 4 x (16 x 1/2) -2
= 32 ÷ 4 × 8 -2
= 8 × 8 - 2 = 64-2
= 62
Answer:
62
Step-by-step explanation:
32/4 x (16 x 1/2) -2
8 x 8 - 2
64-2

Step 1: Define
f(x) = -2x + 3
g(x) = 2x + 3
f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
Step 2: Solve
Substitute in x [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3Multiply: f(3) + g(7) = -6 + 3 + 14 + 3Add: f(3) + g(7) = -3 + 14 + 3Add: f(3) + g(7) = 14Cara's Candles Cara likes candles. She also likes mathematics and was thinking about using algebra to answer a question she had about two of her candles. Her taller candle is 16 cm tall. Each hour it burns makes the candle lose 2.5 cm in height. Her short candle is 12 cm tall and loses 1.5 cm in height for each hour that it burns.
Write an equation for both candles and solve it by either substitution or elimination.
(If someone could please help me out with this, I would really appreciate it. I've been trying to do this for days now and I just can't figure it out..)
(By the way, the equation for the 16 cm candle is y = -2.5x + 16, and the equation for the 12 cm candle is y = -1.5x + 12, I just don't know how to solve it using substitution or elimination.)
please help I don't understand
I WILL give branliest to whoever's right
I really need the answers
Answer: Substitution
Step-by-step explanation: I think that because you have the equations already, you just have to solve for a variable using substitution. Do this by substituting one of the variables with another number. For example, make x=2 in both equations. Now you are free to solve for y and get your answer.
y=-2.5(2)+16
y=11
y=-1.5(2)+12
y=9
You can substitute in any number that makes it easy for you. Also, if you want x, you can substitute y. I'm really, really sorry if that is not helpful, I just told you what I know!

A compound event image occurs when any of the shaded outcomes in the sample space occurs. What is the probability of image?
A.
image
Answer:
[tex]Pr(E) = \frac{1}{9}[/tex]
Step-by-step explanation:
Given
Compound event E
replace "image" with E in the question
Required
The probability of E
From the question, 4 outcomes were shaded.
This implies that
[tex]n(E) = 4[/tex]
And we have:
[tex]n(S) = 36[/tex] --- Sample size
The probability of E is:
[tex]Pr(E) = \frac{n(E)}{n(S)}[/tex]
This gives:
[tex]Pr(E) = \frac{4}{36}[/tex]
Simplify
[tex]Pr(E) = \frac{1}{9}[/tex]
