one leg of a right triangle is twice as long as the other leg, If the hypotenuse side is 5cm long then what is the measure of the shorter leg (you can leave your answer as a decimal or in radical form)
Step-by-step explanation:
Let x be the other leg or the base and the first leg is y or the perpendicular. ATQ,
One leg of a right triangle is twice as long as the other leg,
y = 2x
Hypotenuse, H = 5 cm
For a right angled triangle, using Pythagoras theorem,
[tex]H^2=B^2+P^2[/tex]
Putting all the values,
[tex]5^2=x^2+(2x)^2\\\\25=x^2+4x^2\\\\25=5x^2\\\\x^2=5\\\\x=\sqrt{5}\ cm[/tex]
Other leg,
[tex]y=2x\\\\=2\sqrt{5} \ cm[/tex]
Hence, the measure of the shorter leg is [tex]\sqrt{5} \ cm[/tex]

Isaac's website has been getting more popular, primarily through word-of-mouth advertising.
Each month, he sees a 5% increase in page views. If Isaac's site had 32,400 page views this
month, how many page views can he expect 8 months from now?
Answer: 590.98217751
Step-by-step explanation:
32,400(1+0.05)^8
32,400(1.05)^8
590.98217751
Answer:
47,870
Step-by-step explanation:
Plug in 32,400 page views for the initial amount, 0.05 for the rate of increase, and 8 months for the time elapsed.
y
= a(1+r)t
y
= 32,400(1+0.05)8 Plug in values
y
= 32,400(1.05)8 Add
y

When Jocelyn runs the 400 meter dash, her finishing times are normally distributed with a mean of 61 seconds and a standard deviation of 2 seconds. Using the empirical rule, what percentage of races will her finishing time be between 57 and 65 seconds?
Answer:
95% of races will her finishing time be between 57 and 65 seconds.
Step-by-step explanation:
Mean=61 seconds
Standard deviation =2
Empirical rule says,
68% of data covered between mean±1 standard deviation
95% of data covered between mean ±2 standard deviation
99.7% of data covered between mean ± 3 standard deviation.
I'll upload the Empirical rule curve.
Because 57 is 61-2(2) and 65 is 61+2(2), so, 95% of data covered.
So, according to Empirical rule, 95% of races will her finishing time.

Constance wrote a total of 10 pages over 5 hours.
How many hours will Constance have to spend writing this week in order to have written a total of 20 pages?
Step-by-step explanation:
10 pages in 5 hours.
our focus is on pages (how long for 20 pages).
so, if we don't see the ratio right away, let's norm the original relationship to 1 page :
10 pages in 5 hours
so,
1 page in 5/10 = 0.5 hours = 1/2 hours
and now : how long for 20 pages ?
1 × 20 pages in 1/2 × 20 hours
20 pages in 10 hours.
formally, we are dealing with a ratio, which is a fraction :
10 pages in 5 hours = 10/5
to keep the value of the fraction, in order to change one of the 2 values to a target value (like 10 pages to 20 pages in our case), we need to multiply the other with the same factor :
10/5 × 2/2 = 20/10
so, again, this tells us 20 pages in 10 hours.

Step-by-step explanation:
y equals mx plus c, where m is the gradient(slope of line) & c is the constant
∴y equals (5/4)x-5,where 5/4 represents the "m" & -5 is the constant.
Therefore,5/4 is "m" which is the slope(gradient).
