Answer:
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because.

Given: AC and BD bis, each other.
Prove: ABCD is a parallelogram
Answer:
because AC and BD bis => AX = XC; BX = XD
ΔAXD ≅ ΔCXB (SAS) because: AX = CX
DX = BX
m∠AXD = m∠BXC ( 2 opposing angles)
because ΔAXD ≅ ΔCXB (SAS)
=> AD = BC and m∠DAX = m∠BCX
because m∠DAX = m∠BCX => AD//BC
ABCD has AD = BC and AD//BC => ABCD is a parallelogram

The angles are equal to eachother so 4x-26 = 3x+14
Anyone can help me with this problem
Answer:
R=50 degrees
Step-by-step explanation:
All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:
180= (3x+5) + (11x-1) + (5x+5)
You then combine like terms:
180= (3x+11x+5x) + (5-1+5)
180= 19x+9
Then, subtract 9 from 180:
171= 19x
Then, divide 171 by 19:
9= x
Finally, you plug the value of x into the equation representing angle R:
5 x 9 + 5
45 + 5
50
Find the slope from the points given:
(18, -5), (18, 20)
Answer:
UNDEFINED
Step-by-step explanation:
change in y over the change in x is how you'd find slope, however, x is the same in both of these, making this a limitation not an equation, therefore the slope is undefined 18-18 = 0 -> Anything divided by zero as a slope is undefined.

Step-by-step explanation:
Tara has two bags of marbles. The first bag contains 6 red marbles, 5 blue marbles, and 4 green marbles. The second bag contains 3 red marbles, 2 blue marbles, and 4 green marbles. Tara will randomly select 1 marble from each bag.
What is the probability that Tara will select a blue marble from each bag?
Answer:
The first bag, 1 in 3 and the second, 2 in 9.
Step-by-step explanation:
If there are 15 total marbles in the first bag, and 5 blue, there is a 5 in 15 chance, or 1 out of 3 chance she could pull a blue out of the first bag. The second bag, has 9 in total and 2 blue, so there is a 2 in 9 chance she could pull out a blue from the second bag. Hope this helps!

Answer:
1- A. 3(10÷2) +2·7
2- A. 0.4
3- B. -2.8
4- C. n·6 - 12 = 60
Step-by-step explanation:
Heres the work in case teachers ask:
1. The given expression evaluates to ...
30÷2 + 2·7 = 15 + 14 = 29
A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true
B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29
C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29
D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29
2. You can divide the equation by 10 to find the appropriate value of x.
4/10 = 10x/10 = x . . . . . 4/10 matches choice A
3. The expression simplifies to ...
7.5 -10.3 = -2.8 . . . . . . matches choice B
4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...
n×6 - 12 = 60 . . . . . . . . matches selection C

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number is 40% of 1602
Answer:
A. 160 Out of 40 is 400%./// B. The answer is 25/// C. The answer is 3905%
Step-by-step explanation:
( A ) One step solution:
You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.
So, 160 is 40% of = 160 X 100 = 400
40
( B ) The same thing as A but the numbers are switched
One step solution:
You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.
So, 40 is 160% of = 40 × 100 = 25
160
( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:
1602 - 40 = 1562
Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:
1562 = 39.05
40
We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?
39.05 x 100 = 3905%
160 is percentage of 40, 40 is 160% , number is 40% of 1602 are 64 , 64 and 640.8 respectively.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Problem A,
40% of 160 = 160 x 40 / 100
= 64
Problem B,
160% of 40 = 160 x 40 / 100
= 64
Problem C,
40% of 1602 = 1602 x 40 / 100
= 640.8
Therefore, 160 is percentage of 40, 40 is 160% , number is 40% of 1602 are 64 , 64 and 640.8 respectively.

8а +а – 3 = 6а – 2а - 3
Answer:
a=0
Step-by-step explanation:
Answer: a=0
Step-by-step explanation:
8a+a−3=6a−2a−3
Step 1: Simplify both sides of the equation.
8a+a−3=6a−2a−3
8a+a+−3=6a+−2a+−3
(8a+a)+(−3)=(6a+−2a)+(−3)(Combine Like Terms)
9a+−3=4a+−3
9a−3=4a−3
Step 2: Subtract 4a from both sides.
9a−3−4a=4a−3−4a
5a−3=−3
Step 3: Add 3 to both sides.
5a−3+3=−3+3
5a=0
Step 4: Divide both sides by 5.
5a /5= 0/5
Answer: a=0

Jack wants to buy a piggy bank at 6000 dollars . Black Friday is coming at November 6th and there are 80%of all goods how much will he now pay ?
Answer: 1,200 dollars
Step-by-step explanation:
We know that the cost before the discount is 6,000.
The discount price is 80% off.
So, subtract 4,800 by 6,000 because 80% of 6,000 is 4,800.
Now, we have to add the two zeros. We get 1200.

Julio pald 1.2 times his normal hourly rate for each hour he works over 30 hours a week Last week he worked 43 hours and earned $574.56
Answer:
482.70
Step-by-step explanation:
First, find out how much he earned per hour last week. 576.56 divided by 43 is 13.41.
Second, multiply his hourly earnings by 1.2, 1.2*13.41=16.09 So he earns 16.09 per hour
Lastly, multiply 16.09 by 30, 16.09*30=482.7 So he earns about $482.70 each week.

. Consider the following standards.
MAFS.912.F-BF.1.1b: Combine standard function types using arithmetic operation. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model. MAFS.912.F-BF.1.1c: Compose functions. For example, if T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.
Part A: Describe the difference in combining functions and composing functions.
Part B: Give a real-world example of combining functions.
Part C: Give a real-world example of composing functions.
Part A:
A combined function is defined by combining with existing functions using addition, subtraction, multiplication or division.
A composite function is created by plugging one function into another.
