Answer:

The constant of proportionality is 0.3, or K=0.3.

Step-by-step explanation:
The chart I attached shows points that are plotted on the proportional line. In order to find the constant of proportionality from these points, you have to divide the amount of change by the number of years. For example, 3 divided by 10 or 6 divided by 20. This results in 0.3, which means that every year, there is 0.3 centimeters of change in the sea level.

Christy draws 3 cards from the deck one at a time without replacement. What is the probability of selecting the cards in the ord

Inga [223]

Start with a deck of 52 cards. Draw 1 card. Probability of drawing a diamond first:

$\dfrac{\binom{13}1}{\binom{52}1}$

Now draw another single card from the deck, which now contains 51 cards. Probability of drawing a spade:

$\dfrac{\binom{13}1}{\binom{51}1}$

Draw 1 last card. The deck has 50 cards left, and 12 of these are diamonds. Probability of drawing a diamond:

$\dfrac{\binom{12}1}{\binom{50}1}$

So the probability of drawing a diamond, then a spade, then another diamond is

$\dfrac{\binom{13}1}{\binom{52}1}\cdot\dfrac{\binom{13}1}{\binom{51}1}\cdot\dfrac{\binom{12}1}{\binom{50}1}=\dfrac{13}{850}$

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile

STALIN [3.7K]

Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon
gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.

Answer:

Step-by-step explanation:

It's essential that you use the symbol " ^ " to indicate exponentiation.

Expanding f(x) = (x + 14)^2 results in x^2 + 28x + 196 (which is in standard form)

You need gas for your car, and just as you are approaching where you normally get gas, the radio station announces that the Chea

schepotkina [342]

Answer: Yes

Step-by-step explanation:

Given that:

Distance from present location to CheapGas = 4 miles

Price of gas at CheapGas is $0.37 cheaper

Hence, the decision to make a U-turn back to CheapGas or continue on intended destination will rely on two factors ;

1) The number of gallons of gas to purchase

2) The cost of gas required to return to cheap gas.

If a substantial amount of gas is to be purchased, may be 50, 100 or more gallons, the amount saved by making a turn back to cheapGas and purchase gas at $0.37 cheaper per gallon.
