0.02 times 0.7 = 0.014 all u needed to do was 2 times 7 and add two zeros
Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
32.68346376° = B
32.7° = B
Answer:
<em>x° = 42°</em>
Step-by-step explanation:
<em>x°</em> = 180° - (70° + 68°) = <em>42°</em>
A) 150% of the original price is the increased price.
B) 66.66% of the increased price is the original price.
<u>Step-by-step explanation:</u>
Original price = $300
Increased price= $450
A) the increased price = 450
Percent of the increased price = (450/300) 100
= 150%
150% of the original price is the increased price.
B) percent of the original price= (300/450) 100
= 66.66%
66.66% of the increased price is the original price.
Answer:
no solution
Step-by-step explanation:
x+3y =9
Solve for y
Subtract x from each side
3y = -x +9
Divide by 3
3y/3 = - 1/3x +9/3
y = -1/3x +3
The y intercept is 3 and the slope is -1/3
3x+9y = 45
Subtract 3x from each side
9y = -3x +45
Divide each side by 9
y = -3/9 x +45/9
y = -1/3x +5
The y intercept is 5 and the slope is -1/3
There is no solution
The lines are parallel (same slope) but the y intercepts are different
