Answer:
7.6
Step-by-step explanation:
you just need to multiply 3.8 × 2= 7.6
Answer:
(a) x + y = 63 OR 3x = 63
(b) 21
(c) 42
Step-by-step explanation:
Let Vijay's age be x and Ajay's be y.
Ajay is <u>twice</u> as old as Vijay
==> Ajay's age = 2 × Vijay's age
==> <u>y = 2x</u>
<h3>(a)</h3>
<u>Sum</u> of their ages = 63
==> x + y = 63
<em>Substituting</em><em> </em><em>2</em><em>x</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 2x = 63
==> 3x = 63
<h3>(b)</h3>
<em>Solving the above-obtained equation:</em>
<u>==> x = 21</u>
<h3>(c)</h3>
Ajay's age = 2 times that of Vijay
==> y = 2x
==> y = 2×21
<u>==> y = 42</u>
Answer: 8 and 10 Step-by-step explanation: Consecutive means right beside. For example, the consecutive of 4 is 5 and 3. Since it's asking for EVEN integers, you need to add 2 to the x... for example, the nearest consecutive even number to 4 is 6 (you add 2). Then, solve like normal!
Taking K as the right angle =>
cos (L) = segment LK / hypotenuse
=> cos(L) = segment LK / √ [ (segment LK)^2 + (segment KJ)^2 ]
Answer:
to find the volume use this formula
V=l*w*h
so we multiply 3 by 1 by 2 which makes 6
V=3*1*2
V=6 cubic ft
