Please help with question!
in a circle of radius 17cm calculate the length of a chord which is 8cm from the centre
Answer:
The length of the chord is 30cm
Step-by-step explanation:
Given
[tex]r = 17cm[/tex]
[tex]d = 8cm[/tex]
Required
Calculate the chord length (L)
This is calculated as:
[tex]L = 2 * \sqrt{(r^2 -d^2)[/tex]
So:
[tex]L = 2 * \sqrt{(17^2 - 8^2)[/tex]
[tex]L = 2 * \sqrt{225[/tex]
[tex]L = 2 * 15[/tex]
[tex]L = 30cm[/tex]
The distance y (in miles) that Train A travels in x hours is represented by the equation y=68x . The graph shows the distance that Train B travels. (0, 0) and (1, 64).
Answer:
For train A, the distance traveled as a function of time in hours is written as:
y = 68*x
For train B, we know that it's equation passes through the points (0, 0) and (1, 64)
Remember that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then the slope for the equation of train B is:
a = (64 - 0)/(1 - 0) = 64
Then equation of train B is something like:
y = 64*x + b
Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:
0 = 64*0 + b
0 = 0 +b
then b = 0
This means that the equation for train B is:
y = 64*x
Where again, y is the distance in miles and x is the time in hours.
If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.

A cylindrical soup can has a radius of 1.8 in. and is 6.7 in. tall. Find the volume of the can.
Volume = base area x tall
base area = π x (1.8in)²
base area = 10.179 in²
Volume = 10.179 in² x 6.7 in
Volume = 68.198 in³
Answerthe volume is 68.198 in³

Fran is struggling with her priorities for the next few weeks: homework due tomorrow, an essay due in two weeks, a research outline due by the end of the week, and a test next week. How should she list her priorities, starting with the most important task?
Answer:
C
1. homework
2. research outline
3. test
4. essay
Step-by-step explanation:
The tasks will be prioritized based on the ones with the closest date to today.
Her homework due tomorrow, therefore it is the first priority.
Her research outline due by the end of the week, therefore it is the second priority.
She has a test next week, and therefore it is the third priority.
Then finally, in 2 weeks, she has an essay and as such it should be the fourth priority.
The only option that has these tasks arranged in the correct order of priority based on the most important tasks as I have listed is Option C.

3/5b + (-1/2) = 1/4
solve for the variable.
Answer:
Step-by-step explanation:
(3b)/5-1/2=1/4
(3b)/5=1/4+1/2
(3b)/5=1/4+(1/2)(2/2)
(3b)/5=1/4+2/4
(3b)/5=3/4
3b=15/4
b=5/4
b=1.25

what is the probability of rolling a dice twice and getting a six?
[tex] \huge \boxed{ \fcolorbox{black}{aqua}{Answer}}[/tex]
There are a total of 6 x 6 = 36 possible outcomes when a fair die is rolled twice. Of the 36 possible outcomes, there are 6 doubles: 1-1, 2-2, 3-3, 4-4, 5-5, and 6-6. Thus, the probability of getting a double is 6/36 = 1/6.
Question in the picture
Answer:
y = -5x + 7
Step-by-step explanation:
Since the line you are looking for is parallel to y = -5x + 4, it will have a slope of -5
Now use the point-slope form to continue
y - 2 = -5(x - 1)
y - 2 = - 5x + 5
y = -5x + 7

Gavin drank 3/4 of a liter of orange juice from the container, which was 3/8 of the orange juice that was originally in the container. How much orange juice was originally in the container?
Answer:
Originally there were 2 liters.
Step-by-step explanation:
--
3/8 of the orange juice = 3/4 liter
1/8 of the orange juice = 3/4 ÷ 3
1/8 of the orange juice = 3/4 x 1/3
1/8 of the orange juice = 1/4 liter
Find 8/8, which is one whole.
1/8 of the orange juice = 1/4 liter
8/8 of the orange juice = 1/4 x 8
8/8 of the orange juice = 2 liters
There were originally 2 liters of orange juice in the container

3000? maybe good luck
Answer:
6,000
Step-by-step explanation:
To find the volume, you have to solve the width x length x height.
So, 1 of the containers is 20(W) x 15(L) x 10(H) which equals to a volume of 3,000.Then we have another container with the same dimensions. That means we will add 3,000 because it's the same. 3,000 + 3,000 = 6,000

Find X and missing angle
Answer:
15
Step-by-step explanation:
all triangles are 180 so 180-75-90 =15
Answer:
x = 2.22
missing angle = 15°
Step-by-step explanation:
tan 75° = 12/x
tan 75° = 3.7321
x = 12/3.7321 = 2.22
missing angle = 90° - 75° = 15°
