Step-by-step explanation:
120/20=6g
50/20=2.5g
170/20=8.5g
for one shortbread ^^
6*50=300g
2.5*50=125g
8.5*50=425g
for 50 shortbread ^^
Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
Answer:
<h2> x =
-5 - √15 or x = -5 + √15</h2>
Step-by-step explanation:

Answer:
20 and 90
Step-by-step explanation:
We use the given data above to calculate the volume of gasoline that is being burned per minute by commercial airplanes.
Amount burned of 1 commercial airplane = <span>3.9 × 10³ ml of gasoline per second
Number of airplanes = </span><span>5.1 × 10³ airplanes
We calculate as follows:
</span> 3.9 × 10³ ml of gasoline per second / 1 airplane (5.1 × 10³ airplanes)(60 second / 1 min ) = <span>1.2 x 10^9 mL / min</span>
