It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954
Answer: x = 9.0
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is x
With m∠39 as the reference angle,
the adjacent side of the right angle triangle is 7
The unknown side represents the opposite side of the right angle triangle.
To determine x, we would apply
the cosine trigonometric ratio which is expressed as
Cos θ = adjacent side/hypotenuse. Therefore,
Cos 39 = 7/x
x = 7/cos 39 = 7/0.777
x = 9.0 to the nearest tenth
Answer:
4032?
Step-by-step explanation:
The area of the shaded region should just be basic multiplication.
Answer:
36 and 144
Step-by-step explanation:
Sum the parts of the ratio, 2 + 8 = 10 parts
Divide the sum of the 2 numbers by 10 to find the value of one part of the ratio.
180 ÷ 10 = 18 ← value of 1 part of the ratio, thus
2 parts = 2 × 18 = 36
8 parts = 8 × 18 = 144
Thus 2 numbers are 36 and 144
