We are asked to find the distance Louise cycled.

Speed Louise cycled = 12 mph

Time = 11: 30 am to 12 : 15 pm

= 45 minutes

Convert 45 minutes to hour

60 minutes = 1 hour

45 minutes = 3/4 hour

<em>Speed = Total distance ÷ Total time taken</em>

<em>Distance = Speed × Time</em>

= 12 mph × 3/4 hour

= 36 / 4

= 9 miles

Therefore, the total distance Louise cycled is 9 miles

Vitek1552 [10]

Answer:

Steps 1 - 4 below explains it.

Step-by-step explanation:

The way that the soldiers get across the river and leave the boys in joint possession of the boat is;

1) The two 12- year - old boys will take the boat to the other side

2) Thereafter, one of the 12- year - old boys will return with the boat.

3) A soldier will now take the boat to the other side and the soldier will remain there while the other boy returns the boat.

4) Step 1 - 3 is a total of 4 trips. Thus, trip would be repeated the total of n times and the n number of soldiers would get across the river and leave the boys in joint possession of the boat after the total of 4n trips.

galben [10]

Answer:

second equation

Step-by-step explanation:

10a + 12p = 70  (10 goes with almonds [a], 12 goes with pistachios[p], $10 and $12 is price per pound and $70 is total price, so that's why its = to 70)

a + p = 6.3        (this is total almonds and pistachios adding up to 6.3 pounds)

a = pounds of almonds

p = pounds of pistachios

A dome of a building is in the form of a hemisphere from inside it was whitewashed at the cost of rupees 4989.60 if the cost of
Luda [366]

Answer: 249.48\ m^2; 369.168\ m^3

Step-by-step explanation:

Given

Cost of white-washing =Rs. 4989.60

Rate =20 per meter square

So, inside area of = \dfrac{4989.60}{20}=249.48\ m^2

The surface area of dome= 4\pi\ r^2=249.48

4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m

The volume of air in the dome V=\frac{4}{3}\pi r^3

V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3

Circle V is shown. Line segment T V is a radius with length 14 feet.
lawyer [7]

We have been given graph of circle V with radius 14 feet. We are asked to find the area of the circle V.

We will use area of circle formula to solve our given problem.

A=\pi r^2, where r represents radius of circle.

Upon substituting r=\text{14 ft} in above formula, we will get:

A=\pi(14\text{ ft})^2

A=\pi(14)^2\text{ ft}^2

A=\pi\cdot 196\text{ ft}^2

A=196\pi\text{ ft}^2

Therefore, the area of the circle V is 196\pi square feet and option 'c' is the correct choice.

How to find the domain and range of a function
Rasek [7]

Answer:

The domain of a function is the complete set of possible values of the independent variable. The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

Step-by-step explanation:

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero

The number under a square root sign must be positive in this section

The range is the resulting y-values we get after substituting all the possible x-values.
