Answer:
Step-by-step explanation:
a.
y=0.75x
y-y1=(y2-y1)/(x2-x1)×(x-x1)
y-3=(6-3)/(8-4) (x-4)
y-3=3/4(x-4)
y-3=3/4 x-3
y=3/4 x-3+3
y=3/4 x
if y=f(x)
f(x)=0.75x
c.

Explain why 3/4 of 16 is the same as 3 x 16 divided by 4
Please Help
Answers
Answer:
I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.
Step-by-step explanation:
Since 3/4 is a fraction, all fractions can be converted into decimals.
3/4 is also known as 75%, which can be simplified into 0.75 in decimal terms.
Now that you know that 3/4 can be simplified to 0.75, you now need to take that 0.75, and multiply it by 16. You can use a calculator to do this, or you could work it out on a sheet of paper.
An easy way to do this, is to know that 25%, (0.25) of 16 is 4. This is because 4 times 4 is 16. Knowing this, if you are looking for 75% of 16, (0.75) you can multiply 4 by 3, knowing that it is 75% of 16.
The answer to that is 12.
3 x 16 = 48 and if you take 48 and divide it by 4, you will get 12.
You can explain this by writing; I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.

hope this helps
brainliest appreciated
good luck! have a nice day!
Explanation: Since you are rounding to the nearest hundred, your answer will have 2 digits after the decimal. When the third digit is equal to or greater than 5, you round up previous digit. If the third digit number is lower than 5, you leave the the previous digit as it is.
In this case, the third digit is the number “8” and since it is greater than 5, you round up the digit before it. The 16.7[5]8 turns into 16.7[6].

You increase the lengths of the sides of a cube by the factor 2. What is the ratio of the new cube to the original.
a. 8:1
b. 4:1
c. 1:2
d. 2:1
Answers
Answer:
Answer a (8:1)
Step-by-step explanation:
Surface area or volume?
I will assume it's volume.
The volume formula is V = s^3, where s is the length of one side of the cube. If we double s, we get V2 = (2s)^3, or 8s^3, which is 8 times greater than thevolume of the cube with side length s.
The ratio is then 8s^3/s^3 or 8/1 or 8:1.
What is the probability of tossing a coin twice and getting a head and a tails?
Answers
Answer:
Probability for flipping a coin twice and getting heads: 1/2
Probability for flipping a coin twice and getting tails: 1/2
Probability for getting heads AND tails: 0
Probability for getting heads or tails: 1/2
Step-by-step explanation:
Probability is how likely something happens. Since there is only 2 options, the probability for getting one of them would be 1/2 and getting both of them 0, because you can only get one of them. Probability for getting heads or tails would be the same. I'm not sure what your question was, so I did all possible answers. Hope this helps!

Step-by-step explanation: Again, you have to write the expression. In this case, it would be 3.14x(9.3x9.3)xY=3000. If you simplify, it would be 3.14x86.49xY=3000. You would than multiply 3.14 and 86.49, and it would be about 271. Then, you divide 3000 with 271, and it would be about 11 if you round to the nearest whole number

Triangle DEF is similar to triangle ABC. What is the length of segment EF? (HINT use scale factor) (Leave answer as a fraction)
Answers
We have been given two similar triangles. We are asked to find the length of segment EF.
We know that corresponding sides of similar triangles are proportional, so we will use proportion to solve our given problem.
[tex]\frac{EF}{DF}=\frac{BC}{AC}[/tex]
Upon substituting measure of our given side lengths, we will get:
[tex]\frac{EF}{1}=\frac{5}{13}[/tex]
[tex]EF=\frac{5}{13}[/tex]
Therefore, the length of segment EF is [tex]\frac{5}{13}[/tex] units.

Answer:
h(x) = 10 [tex](0.4)^{x}[/tex]
Step-by-step explanation:
The exponential is of the form
h(x) = a [tex](b)^{x}[/tex]
Use the ordered pairs from the table to find a and b
Using (0, 10 ), then
10 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] - 1 ), thus
a = 10
h(x) = 10 [tex]b^{x}[/tex]
Using (1, 4 ), then
4 = 10 [tex]b^{1}[/tex] , hence
b = [tex]\frac{4}{10}[/tex] = 0.4
h(x) = 10 [tex](0.4)^{x}[/tex]

Answers
Answer:
y = 3[tex]\sqrt{2}[/tex] + 4
Step-by-step explanation:
Create 2 equations using values from the table to find a and b.
Using (0, 10), then
10 = acos0° + b ( cos0° = 1 ), thus
a + b = 10 → (1)
Using (90, 4), then
4 = acos90° + b ( cos90° = 0 ), thus
b = 4
Substitute b = 4 into (1)
a + 4 = 10 ( subtract 4 from both sides )
a = 6
Thus
y = 6cosx° + 4
When x = 45°, then
y = 6cos45° + 4 = 6 × [tex]\frac{\sqrt{2} }{2}[/tex] + 4 = 3[tex]\sqrt{2}[/tex] + 4
