Answer:
Emma
Step-by-step explanation:
Emma ran (3 1/2)×(1000 m) = 3500 m compared to Grace's 380 m. 3500 m is farther, so Emma ran farther.
Answer:
(0,-5) x= 0; y= -5
Step-by-step explanation:
You can solve by using substitution. This means to solve for x on one of the equations then substituting x for the other equation and solving it.
So the plane of Olivia travels from west to east with an elevation of 6.3 km. To summarize everything and to get the speed of the plane, I used the Angle Side Angle Triangle Theorem and also the law of sine and the formula would be the following:
First is to get the distance traveled by the plane within the range of 3 minutes. To get that distance you must get the following variable.
total distance = distance travel from west to Todds position + distance traveled from Todds position to the reach of the elevation
Dt = D1 + D2
first is getting the D1
D1 = sin41 (6.3) / sin 49
(by following the law of sine and the angles is based on the triangle)
D1 = 5.477 km
then get D2,
D2 = 6.3 sin 65 / sin 25
D2 = 13.510
After that get the total distance
Dt = D1 + D2
Dt = 18.987 km
To get the speed of the plane, you must divide the distance to the time (in minutes) then multiply it by 60 to make it as an hour.
Speed = 18.987 /3 * 60 = 379.74 km/hr
Answer:
Yes
Step-by-step explanation:
3 medium cars to 1 small car can be made into a fraction like this: 
or 
. But you must be consistent if the denominator represents medium cars or small cars.
For this, I'm just going to make medium cars the numerator.
18 medium cars to 6 cars can be made into a fraction like this : 
.
When you divide both fractions in a calculator (or in your head), you will realize that they both are the same value (equivalent).
These ratios are equivalent.
