<em>Greetings from Brasil... </em>
Check Attachment!!!
According to the statement of the question, we have:
a/b = 3/4
<em>Note that according to the attached figure, </em><em>b > a</em><em>, then the correct proportion will be </em><em>a</em><em> to </em><em>3</em><em>, as well as </em><em>b</em><em> to </em><em>4</em><em>, because </em><em>b > a</em><em> and </em><em>4 > 3</em>
Isolating a and b:
a = 3b/4
b = 4a/3
From Pythagoras:
h² = a² + b² - as a = 3b/4 and b = 4a/3, so
<h3>b = 4h/5</h3><h3>a = 6h/5</h3>
For Area:
A = b.a/2
as b = 4h/5 and a = 6h/5, so
<h3>A = 12h/25</h3>
Answer:
Step-by-step explanation:
You turn 5 3/5 into an improper fraction, to do that you do 5 x 5 = 25 then 25 + 3 = 28/5
so in a 7 day period she swims 5.6 kilometers. So you have to do 5.6/7 = 0.8
So it would be 0.8 kilometers in a day which is 4/5 kilometers so I don't know if the answers were just wrong?
Answer:
rational, integer, whole, natural, real
Step-by-step explanation:
Trailing zeros after the decimal point do not change the value of a number. This number is 1, a rational, real, integer, whole, natural number.
Answer: x=10 7/8
Step-by-step explanation:
Subtract 3/4 from both sides. Multiply both sides by 3. Divide both sides by 2 (basically just isolate x on one side of the equal sign).
Answer:
<em>20 sq yd</em>
Step-by-step explanation:
To find the total amount of sq yd's of paint needed, you have to find the area.
The area of a triangle is: A = 1/2 bh
We know:
b = base = 8
h = height = 5
Plug in and solve:
A = 1/2 (8) (5)
A = 1/2 (40)
A = 20
