Answer:
y=2x+4
Step-by-step explanation:
y-(-6)=2(x-(-5))
y+6=2(x+5)
y+6=2x+10
y=2x+10-6
y=2x+4
Joel had a coin collection. He had two hundred coins,
which were dimes and quarters. The total value of his
collection was worth $32.
Remember to define your variables.
Create 2 equations
(Each equation should have a "common theme" for
example in this problem one equation will be the the
total number of coins and the other will be the total
value of the coins)
The next step is to solve the problem. Remember to
think of the best method for problem solving
Answer:
Joel's coin collection had 120 dimes and 80 quarters.
Step-by-step explanation:
Given that Joel had a coin collection of two hundred coins, which were dimes and quarters, and the total value was worth $32, to determine how many coins of each type he had, the following equations must be performed:
0.25 - 0.10 = 0.15
200 x 0.10 = 20
32 - 20 = 12
12 / 0.15 = 80
200 - 80 = 120
(80 x 0.25) + (120 x 0.1) = X
20 + 12 = X
32 = X
Therefore, Joel's coin collection had 120 dimes and 80 quarters.
What is the area of the triangle?
16
8
10
Answer:
64
Step-by-step explanation:
Find the area of both triangles inside the bigger triangle and add them together.
Use the Pythagorean theorem to find the missing length of the leg in the smallest triangle:
a² + b² = c²
8² + b² = 10²
64 + b² = 100
36 = b²
6 = b
Calculate the area of the smaller triangle:
1/2(bxh)
1/2(6 x 8)
1/2(48)
24
Calculate the area of the bigger triangle:
We know that the longer leg is 10 units because we were able to subtract the length of the smaller triangle's leg from 16.
1/2(bxh)
1/2(10 x 8)
1/2(80)
40
Add both areas to find the area of the largest triangle:
40 + 24 = 64

Step-by-step explanation:
The average daily balance of a credit card for the month of November was $700, and the unpaid balance at the end of the month was $1,400. If the monthly interest rate is 1.3% of the average daily balance, what is the total balance on the next billing date December 1? Round your answer to the nearest cent.
Answer:
This answer is on quizlet
Step-by-step explanation:
Answer:3255.20
Step-by-step explanation:
First, calculate the interest using the APR in decimal form (divided by 12) and the average daily balance.
Interest =0.27612×$2,400=$55.20
Then add the interest to the unpaid balance.
Total Balance =$3,200+$55.20=$3,255.20

add the total amount of bows then find out of that much how many are purple
Answer:
4/10 (2/5)
Step-by-step explanation:
Add all the bows together and then add ur number to the fraction.
EX: 1 blue bow, 6 purple bows, 6, pink bows what is the possibility to get a blue bow?
Add them all together, and then the denominator would be 13. So, there is one bow which means 1 in a 13 chance you will get the blue bow.

3. Is the function increasing or decreasing?
4. What is the domain and range of the function?
Answer:
See below.
(I only answered the first one b/c the second log function doesn't really make sense, sorry!)
Step-by-step explanation:
1. f(x) = 5 × [tex]3^{x}[/tex]
Plug in 5 points.
x = -2, f(x) = [tex]\frac{5}{9}[/tex]
x = -1, f(x) = [tex]\frac{5}{3}[/tex]
x = 0, f(x) = 5
x = 1, f(x) = 15
x = 2, f(x) = 45
2. Attached below.
3. Increasing
4. Domain: x = all real numbers
Range: f(x) > 0 (because the line never goes below the x-axis)

PLEASE HELP!!!!!! ILL GIVE BRAINLIEST *EXTRA 40 POINTS** !! DONT SKIP :((
the answer is no. the solution is (1.333, 7.333)
Answer: No, it is not a solution
Step-by-step explanation:
Substitute the value of x as 1 and y as 6
y = x + 6
6 = 1 + 6
6 = 7 (no)
-----------------------------------------
y = 4x + 2
6 = 4(1) + 2
6 = 4 + 2
6 = 6 (Yes)
-----------------------------------------
Even though the solution works in the second equation, it does not work in the first
Therefore (1,6) is not a solution to the system of equations

What is the probability of landing on an 8 and then landing on a 7?
Write your answer as a fraction or whole number.
two over four is the probability that you will land on seven or eight
Answer:
P( landing an an 8 then on a 7 ) = 1/ 16
What is a Probability?
Its is the branch of mathematics concerning numerical description of how likely an event is to occur .
P( landing an an 8 then on a 7 ) = P ( landing on an 8) * P ( landing on a 7 )
P(Landing on an 8) = 1/4
P(Landing on an 7) = 1/4
P = 1/4 * 1/4

The height of a cuboid whose volume is 385 cu cm and base area is 35 sq cm is
Answer:
11cm
Step-by-step explanation:
Given data
Volume of cuboid =385 cm^3
Base area= 35cm^2
We know that
Volume = Area* Height
substitute and solve for Height
385=35*H
H= 385/35
H= 11cm
Hence, the height is 11cm

A usability test was conducted to evaluate the design of a store website. The times to complete a certain task were recorded for a sample of 48 users. The sample mean time was 70 seconds with a 95% margin of error of 10 seconds. In other words, researchers estimated with 95% confidence that the mean time to complete the task was between 60 and 80 seconds for all website users. Only one of the following statements is true. Select the correct statement.
1. the probability that the mean time μ will fall between 60 and 80 is 0.95.
2. If many samples are collected from the same population, about 95% of the samples will produce confidence intervals that contain the population mean μ.
3. If a second sample from the same population is selected and a 95% confidence interval is constructed, the new confidence interval will be the same as the 95% C.I. defined in the first study.
4. If the study is repeated, and a new 95% confidence interval is computed, there is 95% chance that the new interval contains the sample mean value >= 40 seconds.
Answer:
2. If many samples are collected from the same population, about 95% of the samples will produce confidence intervals that contain the population mean μ.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
So the correct option is given by:
Option 2, as we will be 95% sure that the population mean will be in the interval, which can be interpreted that from many samples, about 95% will contain the population mean.

0.99 is what percent of 9.90?
Answer:
10%
Step-by-step explanation:
first let's write out the problem
0.99 is what percent of 9.90 = 0.99=9.90*x
We need to what c is so we would do the opposite operation of multiplication, division so we get,
0.99/9.90= .1
now we turn .1 into percent and get out answer
0.1= 10%
Answer:
Step-by-step explanation:
ahh that's like a math tongue twister :P
so just remember that when you are given the final amount, as the 0.99 is, then you want to divide by the total, like this
0.99 / 9.90 =
we don't really need a calculator for this, b/c you can see that the answer will come out to a one, but, where is the decimal, huh
my calculator put the decimal here 0.1
so that's 10% right? which totally makes sense.. right? 0.99 is 10% of 9.90... just move the decimal one place in the 9.9 to get .99 see? so that kinda helps us know where the decimal goes in the answer, if that make sense? The decimal gets moved one place to the LEFT of the one, in our answer when we just did the math in our head.
anyway.. leave a comment if you have more questions :)
