Step-by-step explanation: 1. A=1/2*base*height
12/2=6
2. 6*16*4=512
Answer:
8/3 km
Step-by-step explanation:
we can represent the given information on a table:
Kilometers time (hours)
2/5 ⇔ 1 1/2
and since we want to know how many kilometers (x) will be paved on 10 hours:
Kilometers time (hours)
2/5 ⇔ 1 1/2
x ⇔ 10
The relationship these 3 numbers have can be described by using the <u>rule of three,</u> which is to multiply the cross quantities on the table (2/5 by 10) and then divide by the remaining amount (1 1/2):
x = ÷
x = ÷
we use
x = ÷
and we make the division:
x = ÷ =
we simplify the fraction by dividing the numerator and denominator both by 5, and we get the result:
x =
thus, in 10 hours the crew will pave 8/3 km. Which is about 2.66 km.
Aaa I thought this was a question and was ready to get into full answering mode lol
= sin O - cos O - (sin^2 O + cos^2 O + 2 sin O cos O)
= sin O - cos O - ( 1 + sin 2O)
= sin O + cos O - sin 2O - 1
Answer: Lcm = 600
Step-by-step explanation: Find the prime factorization of 120
120 = 2 × 2 × 2 × 3 × 5
Find the prime factorization of 200
200 = 2 × 2 × 2 × 5 × 5
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:
LCM = 2 × 2 × 2 × 3 × 5 × 5
LCM = 600
