Answer:
B. 1/10 the value of
Step-by-step explanation:
In our base-10 place-value number system, the place value of a number is multiplied by 10 when it moves 1 place to the left. It is multiplied by 1/10 when it moves 1 place to the right.
A digit has 1/10 the value of the same digit one place to its left.
Answer:
Part a) 2.36 quarts
Part b) 47.2%
Step-by-step explanation:
Let
x ---> percentage of the resulting mixture that is antifreeze
Remember that
we know that
3 quarts of a solution multiplied by 0.22 (percentage in decimal form) plus 2 quarts of a solution multiplied by 0.85 (percentage in decimal form), must be equal to 5 quarts of a solution multiplied by x (percentage of the resulting mixture)
so
The linear equation that represent this situation is
solve for x
Convert to percentage
therefore
The percentage of the resulting mixture that is antifreeze is 47.2%
To find out how many quarts of antifreeze are in the resulting mixture, multiply the total quarts of the resulting mixture by the percentage in decimal form
Let's use our trigonometric skills to solve for this one:
Answer:
1. a
2. mode is 14,so I think C
3. a because it was around 100
4. a
5. a
6. b
7. a
8. a
9. b
Answer:
A) 50°, 65°, 65°
B) 45°, 50°, 85°
C) 20°, 60°, 100°
Step-by-step explanation:
To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).
<u>A) 50° + 65° + 65° = 180° (Good!)</u>
<u>B) 45° + 50° + 85° = 180° (Good!)</u>
<u>C) 20° + 60° + 100° = 180° (Good!)</u>
<em>D) 30° + 60° + 70° = 160° (Bad!)</em>
<em>E) 20° + 45° + 120° = 185° (Bad!)</em>
