Answer:

Jimmy reads 0.5 hours.

Step-by-step explanation:

Given:

Number of hours read by Laura = 2 hours

Now Given:

Conner read twice as long as Laura.

So we can say that;

Number of hours read by corner will equal to 2 times Number of hours read by Laura.

framing in equation form we get;

Number of hours read by corner = 2\times 2 =4\ hours

Also Given:

Heather read only one- forth the time that of Conner.

So we can say that;

Number of hours read by heather will be equal to \frac{1}{4} times Number of hours read by Corner.

framing in equation form we get;

Number of hours read by Heather = \frac{1}{4}\times 4 =1\ hours

Again Given:

Jimmy read half the amount of time that heather read.

So we can say that;

Number of hours read by Jimmy will be equal to \frac{1}{2} times Number of hours read by Heather.

framing in equation form we get;

Number of hours read by Jimmy = \frac{1}{2}\times 1 =0.5\ hours

Hence Jimmy reads 0.5 hours.

to estimate the height of the jin mao tower in shanghai , a tourist sights the top of the tower form a mirror that is 86.7 meter
Ray Of Light [21]

Answer:

The height of the tower = 420.48 meters

Step-by-step explanation:

For better understanding of the solution, see the figure attached below :

Let the height of the tower be x meters

Now, using the laws of reflection : angle of reflection = angle of incidence

Also, both the tower and the tourist are standing parallel to each other

⇒ ∠A = ∠i ( Alternate interior angles are equal)

Similarly, ∠D = ∠r ( Alternate interior angles)

But, ∠i = ∠r

⇒ ∠A = ∠D

Also, the tourist and the tower is perpendicular to the ground surface.

⇒ m∠B = m∠E = 90°

Now, in ΔABC and ΔDEC

∠A = ∠D (Proved above)

m∠B = m∠E = 90°

So, by AA postulate of similarity of triangles, ΔABC ~ ΔDEC

As the sides of similar triangles are proportional to each other

\frac{AB}{DE}=\frac{BC}{EC}\\\\\implies\frac{1.92}{x}=\frac{0.4}{87.6}\\\\\implies x=\frac{87.6\times 1.92}{0.4}\\\\\bf\implies x = 420.48\textbf{ meters}

Hence, The height of the tower = 420.48 meters

5. A gardening club has 21 members, of which 13 are males and the rest are
Misha Larkins [42]

If you know that there are 21 members and 13 are females, if you subtract 13 from 21, you will get 8. There are 8 females in the gardening club.

Now you have to figure out the ratio to females to all club members. You already know that there are 8 females and 21 club members. The ratio would be 8:21.

I hope you found this helpful :)
