Answer:

$75\text{ miles, }28\text{ miles}$

Step-by-step explanation:

GIVEN: Emma started biking to the coffee shop traveling $15 \text{mph}$ , after some time the bike got a flat so Emma walked the rest of the way, traveling $7 \text{mph}$ If the total trip to the coffee shop took $9 \text{hours}$ and it was $103 \text{miles}$ away.

TO FIND: how long did Emma travel at each speed.

SOLUTION:

Let the distance traveled by Emma through bike is $\text{x}$

Total time taken when traveled by bike $=\frac{\text{x}}{15}$

Distance traveled through feet $=103-\text{x}$

Total time taken when traveled by feet $=\frac{103-\text{x}}{7}$

Now,

Total time taken $=9\text{hours}$

$\frac{\text{x}}{15}+\frac{103-\text{x}}{7}=9$

$8\text{x}=600$

$\text{x}=75$

Distance traveled through feet $=103-75=28\text{miles}$

Hence distance traveled using bike is $75\text{miles}$ and by feet is $28\text{miles}$

the radius of wheel of a bicycle is 40 cm. taking pie =3.14, a)find tthe circumference of the wheel.b) find the distance covered

monitta

Answer:

a)=251.2 cm b)=50240 cm

Step-by-step explanation:

a) The formula for calculating the circumference of a circle is c=d*pie, where D is the diameter of the circle.

Therefore, C = 2 * 40 * 3.14 = 251.2 cm

b) The distance covered by 200 revolutions of the wheel is 200 times the circumference, 200*251.2=50240 cm.So to think about this we can assume that there is a point A on the wheel, the distance that point A travels when it rotates 200 times.

Answer:

- 1/4

Step-by-step explanation:

Where you see X, substitute with 1/3

Solve the power/exponent first:

6(1/3) = 2

That is ; - 4(1/4)^2

Solve the parenthesis:

(1/4)^2 = 1/16

-4(1/16)

= - 1/4
