27 km
36 km
What is the length of the hypotenuse?
Answer:
The length of hypotenuse is 45 kilometers
Step-by-step explanation:
Assuming that given lengths are of perpendicular and hypotenuse, and the triangle is a right angled triangle
Perpendicular = P = 27 km
Base = B = 36 km
Hypotenuse = H = ?
We can use Pythagoras theorem for finding the length of hypotenuse
The Pythagoras theorem is given by:
[tex]H^2 = B^2+P^2[/tex]
Putting the values, we get
[tex]H^2 = (36)^2 + (27)^2\\H^2 = 1296 + 729\\H^2 =2025[/tex]
Taking square root on both sides
[tex]\sqrt{H^2} =\sqrt{2025}\\H =45[/tex]
Hence,
The length of hypotenuse is 45 kilometers

An ice cream shop uses 6 bananas to make 4 identical sundaes. How many bananas are used in each sundae?
Answer: 1.5 bananas per sundae
Step-by-step explanation:
There was a total of 6 bananas used in making 4 sundaes.
To find the number of bananas used per sundae, you should divide the number of bananas by the number of sundaes.
= No. of bananas / No. of sundaes
= 6 / 4
= 1.5 bananas per sundae

Answer:
[C] 52
Step-by-step explanation:
If line SQ bisects angle RST, that means it splits it in half. This would make angles RSQ and QST equivalent.
So that means that angle RSQ would equal 26
Since the question is asking for angle RST (the whole angle), you would add both of the angles
26 +26 = 52

Line of best fit: b = 0.40n+30 The average cost of each extra call is 40 cents.Pete pays 43.60 dollars in a month when he makes 34 calls.Please read the disclaimer below.
=============================================
Explanation:
Disclaimer: The issue is that without the coordinate values, it's impossible to determine the regression line. It's not clear where some (or most) of the red points are located. Often that's why a table is needed. I would ask your teacher for clarification.
With that said, I'll still give it a shot.
---------------
Part 1
The blue regression line appears to go through the two points (0,30) and (50,50). Let's find the slope through this line
m = (y2-y1)/(x2-x1)
m = (50-30)/(50-0)
m = 20/50
m = 0.40
The y intercept is b = 30 since the blue line appears to cross the y axis at this location.
So y = mx+b turns into y = 0.40x+30
Replace x with n and replace y with b
We go from y = 0.40x+30 to b = 0.40n+30 which is the regression line.
Again this is all based on the assumptions that the blue line goes through (0,30) and (50,50).
---------------
Part 2
Assuming we have the correct regression equation, we can immediately see that each extra call costs $0.40 which is the same as 40 cents. So it's 40 cents per call. This is the slope value, which is the rate of change. Each time n goes up by 1, b goes up by 0.40
Because the regression line estimates the actual observed values, we won't always land on a red point. But the goal is to get as close as possible.
----------------
Part 3
Again assuming we have the correct regression equation, we plug in n = 34 and evaluate to determine the bill
b = 0.40*n + 30
b = 0.40*34 + 30
b = 43.60
Pete would pay $43.60 if he made 34 calls.

The weather forecast says there’s 70% probability of rain tomorrow. What are the odds against rain
Answer:
30%
Step-by-step explanation:
Key skills needed: Probability
1) There is a 70% chance of rain.
2) We need to find the chances against rain.
3) To do this, we need to use the fact that
70% + x = 100% (Since all the probabilities add up to 1 or 100%)
4) If you subtract 70% from both sides, x = 30%
5) This means the probability against rain is 30%.

please just explain how to do this lol ty <3
Step-by-step explanation:
1. Increase amount = 40-25=15 Increase percent = (15/25)×100%= 60%.
2.Increase amount = 30-15 = 15. Increase percent = ( 15/15)× 100% = 100%.
3. Increase amount= 50-18=32 Increase percent= (32/18) x100% = 177.77%
4. Increase amount= 80-22=58 Increase percent= (58/80) x 100% = 72.5% -----> 73% (when rounded of to the nearest 10's).
5. Increase amount= 18-16=2 Increase percent = (2/18)×100 %= 11.111...% -----> 11% (when rounded of to the nearest 10's).
6. Increase amount = 10-3=7 Increase percent= (7/10)×100% = 70%.
7. Increase amount = 100-85 = 15 Increase percent = ( 15/100) × 100% = 15%
