Option B

2 times the length of Noah's bike ride was Mai's bike ride

<h3>Solution:</h3>

Given that Mai biked 7 and 1/4 miles today and Noah biked $3\frac{5}{8}$ miles

We have to find how many times the length of Noah's bike ride was Mai's bike ride

Let "a" be the number that denotes how many times the length of Noah's bike ride was Mai's bike ride

From given information,

Distance biked by Mai = $7\frac{1}{4} \text{ miles}$

Distance biked by Noah = $3\frac{5}{8} \text{ miles}$

So to find how many times the length of Noah's bike ride was Mai's bike ride, we can frame a equation as:

"a" times distance biked by noah is equal to distance biked by mai

$\text{ Distance biked by Mai } = a \times \text{ Distance biked by Noah }$

Substituting the known values we get,

$7\frac{1}{4} = a \times 3\frac{5}{8}\\\\\frac{4 \times 7+1}{4} = a \times \frac{8 \times 3 +5}{8}\\\\\frac{29}{4} = a \times \frac{29}{8}\\\\\frac{1}{4} = \frac{a}{8}\\\\a = 2$

Thus 2 times the length of Noah's bike ride was Mai's bike ride

Answer:

y=√x+5 -1

the answer is option C,,

x=-7,y=√-7+5 -1=√-2 -1

we can't find the square root of negative values, therefore it displays as error

x=-6,y=√-6+5-1=√-1 -1

same reason

x=-5,y=√-5+5-1=√0-1=-1

x=-4,y=√-4+5-1=√1-1=0

x=-1,y=√-1+5-1=√4-1=1

x=4,y=√4+5-1=√9-1=2

A plane has an airspeed of 111 km/h. It is flying on a bearing of 79 degrees while there is a 25 km/h wind out of the northeast

qwelly [4]

Answer: Ground Speed = 91 km/hr, Bearing = 189°

Step-by-step explanation:

Step 1: Draw a picture (see attached) to determine the angle between the given vectors. Notice that I moved the wind vector 180° so the head of the wind vector would line up with the tail of the plane vector. This created an angle of 34° between the plane and wind vectors. Why?
