Answer:
She is 13.45 meters from her starting point.
Step-by-step explanation:
Use Pythagorean Theorem (a^2+b^2=c^2) so 9^2+10^2=c^2. Solve it algebraically and you get c= 13.45 (rounded to nearest hundredth).

Greta can bike 6 miles in 30 minutes. At that rate, how many miles can she bike in 45 minutes?
Answer: 9 miles
Step-by-step explanation:30 divided by 6 is 5. So the was biking 1 mile every 5 minutes. 45 divided by 5 is 9.
Feet up a ratio for miles over time:
6/30 = x/45
Cross multiply:
30x = 270
Divide both sides by 30:
X = 270/30
X = 9 miles
There is no options to choose from and I need to find slope help due today
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
To find the slope we need two points.
A = ( -2 , 5 ) & B = ( 0 , 2 ) & C = ( 2 , -1 )
I choose A and B .
_________________________________
We have following equation to find the slope using two points.
[tex]slope= \frac{y(B) - y(A)}{x(B) - x(A)} \\ [/tex]
Now just need to put the coordinates in the above equation.
Let's do it...
[tex]slope = \frac{2 - 5}{0 - ( - 2)} \\ [/tex]
[tex]slope = \frac{ - 3}{2} \\ [/tex]
[tex]slope = - \frac{3}{2} \\ [/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
I suggest to find the slope using A , C
and B , C to can understand exactly what did I do buddy.
Good luck ♥️♥️♥️♥️♥️

B is between A and C. AB = 5 and AC = 8. What is the length of BC
Answer:
BC = 3
Step-by-step explanation:
If you picture A, B, and C on a line, the first part of the line, AB, has a length of 5 and the total line, AC, has a length of 8 . Means that the second part of the line, BC, has a length of 3 because you would add the length of both the first and second part of the line in order to get the total length of the line.
AB + BC = AC
5 + BC = 8
BC = 3
If one Chinese yaun equals 13.2455 Japanese yen then one Japanese yen equals approximately how many Chinese yuan
Answer:
0.755 Yuan
Step-by-step explanation:
You already know it's going to be less than 1 since 1 yuan is 13.2455 yen.
Chinese Yaun : Japanese Yen
1 : 13.2455
divide both by 13.2455 to work out 1 Japanese Yen
0.0755 : 1
Multiply both 10
0.755: 10

an open tank has tge shape of circular cone. the tank is 8feet across the top and 6 feet high. watwr is pumped through the buttom of the tank. how much work is done to fill the tank from a depth of 4 feet to a depth of 6 feet? water weighs 62.4 pounds per cubic foot
Answer:
[tex]W=22652.98ft-lb[/tex]
Step-by-step explanation:
We are given that
Height of tank=6feet
Diameter of tank=8 feet
Radius of cone,r=d/2=8/2=4 feet
Let a layer of thickness dy at distance yr from the bottom at origin
y=6 feet
Using similar triangle property
[tex]\frac{r}{y}=\frac{4}{6}=\frac{2}{3}[/tex]
[tex]r=\frac{2}{3}y[/tex]
Weight of water=62.4 pounds per cubic foot
Now,
Weight of layer=[tex]62.4\times \pi r^2 h=62.4(\frac{4}{9}\pi y^2 dy[/tex]
Now, work done to fill the tank from a depth of 4 feet to a depth of 6 feet is given by
[tex]W=\int_{a}^{b}62.4\times \frac{4}{9}\pi y^2(y) dy=\int_{4}^{6}62.4\times \frac{4}{9}\pi y^3 dy[/tex]
[tex]W=\frac{62.4\times 4\pi}{9}[\frac{y^4}{4}]^{6}_{4}[/tex]
[tex]W=\frac{249.6\pi}{36}(6^4-4^4)[/tex]
[tex]W=22652.98ft-lb[/tex]
