find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x
16x + 8
10x + 4
12x + 4
8x + 2
Answer:
12x+4
Step-by-step explanation:
To find the perimeter of any shape you just have to take the sum of all the sides.
In this case you would write:
4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)
Now you just have to simplify the expression which would give you:
12x+4 (after collecting like terms)
So the final answer will be 12x+4

Find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards.
Answer:
A deck of cards contains RED cards numbered 1,2 and BLUE cards numbered ... Patricia will draw 8 cards from a standard 52-card deck with replacement. ... Outcome: any of the possible results of an experiment in probability. ... Correct answers:$\frac{7}{9}$7/9 ... Event A: rolling a 6-sided fair number cube and getting 1Step-by-step explanation:
The probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.
To find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards, we need to calculate the probabilities of each event and then multiply them together since the events are independent (the outcome of one event does not affect the outcome of the other event).
1. Probability of rolling an odd number on a fair number cube:
A fair number cube has 6 faces with numbers 1 through 6. Out of these, three numbers are odd: 1, 3, and 5. So, the probability of rolling an odd number is 3/6, which simplifies to 1/2.
2. Probability of drawing a 7 of any suit from a standard deck of cards:
A standard deck of cards has 52 cards. There are four 7s in the deck (one for each suit: hearts, diamonds, clubs, and spades). So, the probability of drawing a 7 is 4/52, which simplifies to 1/13.
Now, multiply the probabilities together:
Probability = (Probability of rolling an odd number) * (Probability of drawing a 7)
Probability = (1/2) * (1/13)
Probability = 1/26
Therefore, the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.

Jeff had $20. He spent 3/8 of his money on lunch. How much money does jeff have left?
Answer:
$12.50
Step-by-step explanation:
3/8 x 20/1 = 7.5
20 - 7.5 = 12.50
Jeff has $12.50 left after spending 3/8 of his money on lunch.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Jeff had $20.
Jeff spent 3/8 of his money on lunch.
To find the money he left after spending on lunch we get by subtracting three by eight from one.
1 - 3/8
=8-3/8
= 5/8 of his money left.
To find out how much money Jeff has left, we can multiply the remaining fraction by his initial amount of money:
Intitial amount is 20
The money left is 5/8.
Multiply five by eight with twenty.
Money left = (5/8) × $20
Five divided by eight times of twenty.
=100/8
When hundred is divided by eight we get twelve point five.
= $12.50
Therefore, Jeff has $12.50 left after spending 3/8 of his money on lunch.

If 47 Mph was a unit rate, how many hours would it take to travel 1 Mph?
Answer: um i think you asked the question wrong. But ok.
Step-by-step explanation:
= 47 miles per hour
This is a fraction equal to
47 miles ÷ 1 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
47 miles ÷ 1
1 hours ÷ 1
=
47 miles
1 hour
=
47 miles
hour
= 47 miles per hour
Answer:
It would take you a total of .021 of an hour to get there.
Step-by-step explanation:
So, you are asking if 47 mph was a unit rate, how long would it take to travel 1 mile? Ok, so you would convert this to a unit rate, which would be 1 hour.47 miles because you are trying to get the 47 to a 1. Next, you will divide both numbers by 47, giving you .0212765957/1. This rounds to .021/1.
