Answer:
2√5
Step-by-step explanation:
The side ratios in a 30-60-90 triangle are ...
1 : √3 : 2
The longest side (x) is 2 times the length of the shortest side (√5), so ...
x = 2√5
Answer:
B = 40° and D = 60°
Step-by-step explanation:
Just subtract the angles you already know from 90° (since perpendicular means right angle, which is 90°).
1.)100+80+7+0.5+0.04 or you could do it like 2.)1x100+8x10+7x1+5x0.1+4x0.01
11 miles in 1/4 hour
1/4 of an hour is 15 minutes
so 11 in 15 minutes
x /60 = 11/15
cross multiply
x*15 = 60 * 11
15x = 660
divide both sides by 15
x = 44
the unit rate of the hikers in miles per hour is 44 mph.
You can also solve like this
1/4 of hour is 15 minutes
to get to the whole hour you would multiply by four
so you'd (11miles in 1/4 hour) * 4
44 miles in 1 hour
Hope this helps :)
The normal price is gotten by find the 5% discounted price and adding it to the amount paid.
The normal price is £580
<h3>Prices and Discounts</h3>
Given Data
Discount = 5%
Amount paid = £551
Let the normal price be x
let us find 5% of x
= 5/100 *x
=0.05x
Hence the discounted amount is £0.05x
We know that the amount paid = Normal Price - Discount
Substituting our data
551 = x-0.05x
551 = 0.95x
Divide both sides by 0.95
x = 551/0.95
x = £580
