t < 73.68
Hello There!
The answer you have selected, (D) is correct!
To get the answer you simply add the two fractions together. and 9 + 4 = 13.
13/10 is also called an irrational fraction, the more you know~
Have a great day, and maybe brainliest?
Answer:
A = 48, and B = 52
Step-by-step explanation:
Simplify 8 = 2 hours to 4 = 1 hour, then multiply 4 times 12 to get the answer to a. The answer to b would be multiplying 4 times 13.
Answer:
x = 3.85
Step-by-step explanation:
Given equation:
6ˣ = 1,000
now,
on taking log both sides, we get
⇒ log(6ˣ) = log(1,000)
or
⇒ log(6ˣ) = log(10³)
now we know the property of log function that
log(aᵇ) = b × log(a)
thus, applying the above property, we get
⇒ x × log(6) = 3log(10)
or
⇒ x × log(2×3) = 3log(10)
now,
we have another property of log function as":
log(A) = log(A) + log(B)
therefore,
x × [log(2) + log(3)] = 3log(10)
also,
log(10) = 1
log(2) = 0.3010
log(3) = 0.4771
Thus,
⇒ x × [0.3010 + 0.4771 ] = 3 × 1
or
⇒ x × 0.7781 = 3
or
⇒ x = 3.85
Answer:
29.5cm^2
Step-by-step explanation:
3 × 4 = 12
4 × 2.5 = 10
3 × 2.5 = 7.5
12+10+7.5=29.5
