Harvey collects marbles. He has 112 marbles. Each tray holds an equal number of marbles. If he uses 7 trays to hold all of the m

Galina-37 [17]

Harvey has 112 marbles and 7 trays that hold an equal number of marbles each. To find the number of marbles in 3 trays, you need to find the number of marbles that each tray holds. In order to do this, you need to divide:

112/7 = 16
(number of marbles divided by the number of trays)

This gives you 16, which is the number of marbles in 1 tray. To find the number of marbles in 3 trays, you need to multiply the number of marbles in each tray times the number of trays:

16 x 3 = 48

So, Harvey will display 48 marbles on 3 trays.

In the diagram abc=adb=90, ad=p and dc=q. Use similar triangles to show that x2=pz<br> plzz anyoneee

kramer

Answer:

By comparing the ratios of sides in similar triangles ΔABC and ΔADB,we can say that $x^{2} =pz$

Step-by-step explanation:

Given that ∠ABC=∠ADC, AD=p and DC=q.

Let us take compare Δ ABC and Δ ADB in the attached file , ∠A is common in both triangles

and given ∠ABC=∠ADB=90°

Hence using AA postulate, ΔABC ≈ ΔADB.

Now we will equate respective side ratios in both triangles.

$\frac{AB}{AC}= \frac{AD}{AB}=\frac{BD}{BC}$

Since we don't know BD , BC let us take first equality and plugin the variables given in respective sides.

$\frac{x}{z}= \frac{p}{x}$

Cross multiply

$x^{2}=pz$

Hence proved.
