Answer:
1. 37.5 metres.
2. 33.33 metres (May be wrong due to the answer but I used the correct solution to find the answer)
3. Refer to explanation.
Step-by-step explanation:
1. Find out how much Logan and Mila both swam.
1/3 of an hour =
60 minutes ÷ 3 = 20 minutes
Logan swam 750 metres for 20 minutes.
Mila swam 2/3 of Logan's distance.
Find out how much is 1/3 of Logan's distance in 1/4 of an hour.
3/3 = 750
1/3 = 750 ÷ 3 = 250
2/3 = 250 x 2 = 500
1/4 of an hour =
60 minutes ÷ 4 = 15 minutes
Mila swam 500 metres in 15 minutes.
To find out Logan's average swimming speed, here's the formula:
Total distance/total elapsed time
So it is 750/20 which is 37.5 metres.
2. Use the same formula I mentioned above in question 1 for average swimming speed, so it is...
500/15 = 33.33 metres
3. Other ways to compare Mila's and Logan's swimming speed is to find out the difference of the distance of how long they swam.
Use Mila's average swimming speed and find out how much metres she would swim if she swam for 20 minutes.
33.33 metres x 20 minutes = 666.6 metres

Step-by-step explanation:
we need to find the length of the rectangle. To do that, we must find the hypotenuse of the right triangle below the rectangle.
Finding the hypotenuse of a right triangle uses the Pythagorean theorem, or a² + b² = c²
let a be 9 and b be 7.
9² + 7² = c²
81 + 49 = c²
130 = c²
√130 = c
c = approx. 11.4
Now, we know the length of the rectangle.
Once a rectangle is cut diagonally, it forms 2 equal right triangles. We will use the same process to find the hypotenuse of the second right triangle.
9² + 11.4² = c²
81 + 130 = c²
81 + 130 = approx. 211
c² = 211
√211 = c
c = approx. 14.5

what is the slope help pls?
Answer:
y=7x-6
Step-by-step explanation:
You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say
y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.

How many solutions are shown by the graph of the quadratic function? A zero B one C two D three
A solution to a quadratic is the same as the root or x intercept (when talking about real numbers). The graph shows that we have exactly one x intercept, which is where the parabola touches the x axis. So we have one root.
in the interval 0° ≤ x ≤360°, find the values of x for which tan x =1.3562 Give your answers to the nearest degree
Answer:
The answers are 54 degrees and 234 degrees
Step-by-step explanation:
mathematically we have the tan positive on only two axes
these are the first (0-90) degrees and the 3rd quadrant (180-270)
We start by find the arc tan of the angle value
Thus;
x = arc tan (1.3562)
x = 54 degrees
On the third quadrant, we have it that;
180 + 54 = 234 degrees

A flower garden is circular. The diameter of the garden is 20 feet. Which is the closest to the total area of the garden?
Answer:
40
Step-by-step explanation:
The total area of the garden is 31.75 sq meters
The first step is to calculate the radius if the circle
The diameter of the garden is 20 feet
2π × radius= 20
2π × 3.14= 20
6.28π= 20
π= 20/6.28
π= 3.18
The area of the flower garden can be calculated as follows
= π × radius²
= 3.14 × 3.18²
= 3.14 × 10.1124
= 31.75 sq meters
Hence the total area of the garden is 31.75 sq meters
