Answer:

3/4

f(x)=3•2^x

Let x = -2

f(-2)=3•2^-2

Exponents first  ( We know a^-b = 1/ a^b)

f(-2)=3• 1/2^2

What is the measure of angle 6, if lines x and y are parallel, and angle 7 measures 121°? 121° 69° 59° 49°
Marianna [84]

Answer:

59°

Step-by-step explanation:

From the diagram, shown in the attachment line x and y are parallel lines.

Angle 7 and angle 6 are angles on a straight line.

The two angles will add up to 180 degrees.

\angle 7+\angle 6=180

But angle 7 measures 121°.

This implies that:

121+\angle 6=180

Solve for angle 6 to get;

\angle 6=180-121\

\angle 6=59\degree

PLEASE HELP IM IN A BIG HURRY

First, change the fraction (decimal and percent) into gallon
Martha used 17% of the total oil, that means
Martha = 17% × 8 gallons
Martha = 0.17 × 8 gallons
Martha = 1.36 gallons

Brett used 0.18 of the total oil
Brett = 0.18 × 8 gallons
Brett = 1.44 gallons

Mike used 0.7 gallons

Second, compare the number of gallon they used
1.36
1 acts as ones
3 acts as tenths
6 acts as hundreths

1.44
1 acts as ones
4 acts as tenths
4 acts as hundreths

0.7 or 0.70
0 acts as ones
7 acts as tenths
0 acts as hundreths

Compare the ones, 1.44 and 1.36 both have 1 as the ones, however 0.7 has 0 as ones. Because 1 is greater than 0, 1.44 and 1.36 are greater than 0.7.
Now compare the tenth, 1.44 has 4 as the tenths, and 1.36 has 3 as the tenths. Because 4 is greater than 3, 1.44 is greater than 1.36.
1.44 > 1.36 > 0.7
Brett > Martha > Mike
Brett used the greatest amount of oil
