assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]
given log(ab) = log(a) + log(b)
log_2(48) = log_2(3) + log_2(16)

The United States has a total area of 3,796,742 square miles.
Estimate the total square area as a single digit times a power of
10. (use rounding and then convert it into scientific notation)
Show work.
Answer:
4 * 10^6
Step-by-step explanation:
3,796,742 is about 4,000,000
4 * 10^? = 4,000,000
4 to 4,000,000 is an extra 6 zeroes
? = 6

Number of basketball players that have signed up for a new league. What is a possible scenario that would be modeled by this equation? Consider how many teams in the league and the number of players on each team this equation could describe
Complete question :
consider the equation x/5-2=11. if x represents the number of basketball players that have signed up for a new league, what is a possible scenario that would be modeled by this equation?
Answer:
Kindly check explanation
Step-by-step explanation:
The Number of players that signed up for a new league can be modeled using the following information :
The number of players per team
The number of teams in the league
For the equation given :
x/5 - 2=11
x could represent the total number of players, with the number of teams in the league being 5 ;
if 2 players were to leave any of the teams ; we have 11 players in that team.
Answer:
The equation could model a scenario determining the number of players on each team in a league of five teams, if 2 players have to be taken out of the possible players to be referees and to keep score. There will be 11 players on each team.

Elena walked 20 minutes more than Lin. Jada walked twice as long as Elena. Jada walked for 90 minutes. The equation 2(x + 20) = 90 describes this situation. Match each amount in the story with the expression that represents it
Answer:
ANSWER BELOW
Step-by-step explanation:
2(X+20)=90
X+20= 90/2
X+20=45
X= -20+45
x=25
^ Lin walks 25 minutes, representing "x".
in the expression (x+20)= The amount Elena walks cause she walks 20 more minutes than Lin.
Therefore Elena walks for (25+20)=45 minutes . (i subsituted 25 for x)
this part -> (x+20) = represents the amount elena walks.
Jada walks 2 times as much as elena= therefore
2(25+20)=90 minutes

Answer:
x = 5.8 ( rounded to nearest tenth)
Answer:
5.8 foot
Step-by-step explanation:
With reference angle 71
perpendicular (p)= x
base(b) = 2
Now
tan 71 = p/b
2.9 = x / 2
x = 5.8 foot

Robert's new hybrid car has a gas tank that holds 12 gallons of gas. When the tank is full, they can drive 420 miles. Assume that their car uses gas at a steady rate.
a. What is the unit rate:
b. Write the equation:
c. Use your equation to find out how many gallons of gas Robert will need to drive 287 miles. 287miles =
gallons of gas
Answer:
sorry i only know the answer of c
it's 8.2 gallons
Step-by-step explanation:
12 gallons = 420 miles
12 gallons = 420 miles? gallons =287 miles
420 miles ÷ 12 gallons = 35miles/gallon
420 miles ÷ 12 gallons = 35miles/gallon287 miles ÷ 35 miles/gallon = 8.2 gallons
Answer:
Step-by-step explanation:
Unit rate = (420 miles)/(12 gallons) = (420/12 miles)/gallon = (35 miles)/gallon
:::::
Fuel consumption = (number of miles) × (1 gallon)/(35 miles)
:::::
287 miles × (1 gallon)/(35 miles) = 8.2 gallons

Question 19
I need answer plss
Answer:
D. 720 kmph
Step-by-step explanation:
Distance = rate • time.
First, we must find the distance covered when the airplane flies 240 km/hr in 5 hours.
D = 240 • 5
D = 1200 km.
Now the question is asking us, to travel 1200 km in 1 2/3 or 5/3 hours, how fast must we travel at? We can use the same equation, except this time we know the distance and the time, we need to solve for the rate.
1200 = r • 5/3
1200 ÷ (5/3) = r
1200 ÷ 5/3 = 1200 • 3/5 = 0.6 • 1200 = 720.
Therefore, the airplane must travel at a speed of 720 kilometers per hour.

Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56
