Answer:
Step-by-step explanation:
a) 8.23 x 10^5 move the decimal over 5 places, 319000000 is 319 million move the decimal over until there is one number on the left side --> 3.19 x 10^8
b) 3.19 x 10^8 / 8.23 x 10^5 = 387.61 roughly 388 times larger
Answer:
Step-by-step explanation:
The sides of a 45°-45°-90° triangle are in the ratio 1:1:√2
The side opposite the 90° angle is 12√2.
a = c = (12√2)/√2 = 12
The sides of a 30°-60°-90° are in the ratio 1:√3:2.
The length of the side opposite the 30° angle is 12 units.
d = length of side opposite 60° angle = 12√3 units
b = length of side opposite the 90° angle = 2×12 = 24 units
The square root of 13 rounded to the nearest tenth is 3.6, so you would plot this somewhere in between 3 and 4 on a number line.
Answer:
b-80 d-6
Step-by-step explanation:
100% correct
Answer:
First we need to find 1/3 of 24. When you see "of" replace it with "×".
1/3 of 24 =
1/3 × 24 =
24/ 3 = 8
So 8 stamps are animals. Now we find 3/4 of 8 to find out how many have birds.
3/4 of 8 =
3/4 × 8 =
24/4 = 6
6 have birds
Step-by-step explanation:
24/3 = 8 stamps with pictures of animals, 8 x 3/4 = 6 stamps with birds on them. If it helps 8 has a denominator of 1 so you just multiply the top and the bottom of the fractions. 8x3=24 and you divide that by 4x1
