Answer:
[tex]r \cdot 4 = z[/tex]
Step-by-step explanation:
An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.
John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.
[tex]r \cdot 4 = z[/tex]
r = how much he runs per day
4 = how many days he runs
z = how much he runs this week
This is your expression!
Answer:
r * 4 = a
Step-by-step explanation:
If John runs the same amount everyday (r) for the past four days, we can multiply 4 by r
r * 4
We don't have enough information to write the answer to the expression so in its place we can put a variable. (In this case, I chose a)
r * 4 = a
So a possible expression for this problem is r *4 = a
Hope this helps! Have a great day! :)
If a pencil is 13.5 cm long and if 1 cm is 0.39 inches what is the length of a pencil in feet to the nearest hundredth
Answer:
0.44 feet
Step-by-step explanation:
The value of the length of the given pencil will be 0.43875 feet.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
Another example could be kilo gram to gram.
Given the length of the pencil
Lenght = 13.5 cm
Also,
1cm = 0.39 inches
So,
Lenght = 13.5 × 0.39 = 5.265 inches.
Now,
Since 12 inches = 1 feet ⇒ 1 inch = 1/12 feet
So,
Length = 5.265/12 = 0.43875 feet.
Hence "The value of the length of the given pencil will be 0.43875 feet.".

Step-by-step explanation:
5-(-7) = 12/2 = 6 so 6 units from 5 is -1 and 21-(-9) is 30/2=15 so 15 from 21 is 6
A cardboard box, which weighs 0.6 pound when empty, is filled with 15 bags of beans and a 4-pound bag of rice. The total weight of the box and the contents inside it is 25.6 pounds. One way to represent this situation is with the equation 0.6+15b+4=25.6 Select all equations that are also equivalent to 0.6+15b+4=25.6
Step-by-step explanation:
Given that,
When a cardboard box is empty, its weight is 0.6 pounds.
It is filled with 15 bags of beans and a 4-pound bag of rice.
The total weight of the box and the contents inside it is 25.6 pounds.
Let the weight of 15 bean bags is 15b. The given scenario can be represented by the equation as follows :
0.6+15b+4=25.6 ....(A)
Taking like terms together,
15b=25.6-0.6-4 ...(1)
15b = 21 ....(2)
Equation (1) or (2) can be the equivalent equation for the equation (A).

The animal shelter had a special on adoption rates for their dogs and cats. Each dog adoption fee was $75 and each cat adoption fee was $35. On Christmas Eve, the animal adopted out 8 total animals and brought in $400 in total adoption fees. How many dogs and how many cats were adopted out on Christmas Eve?
dogs:
cats:
Answer:
3 dogs and 5 cats were adopted out on Christmas eve.
Step-by-step explanation:
Let the number of dogs adopted out on Christmas eve be x and the number of cats be y.
From the question,
On Christmas Eve, the animal adopted out 8 total animals
That is, x + y = 8 ...... (1)
and brought in $400 in total adoption fees.
Also from the question,
Each dog adoption fee was $75 and each cat adoption fee was $35.
∴ On Christmas Eve,
75x + 35y = 400 ...... (2)
Now, to determine how many dogs and how many cats were adopted out on Christmas Eve, we will solve the two equations simultaneously.
From equation (1)
x + y = 8
Make x the subject of the relation.
∴ x = 8 - y ...... (3)
Substitute the value of x into equation (2)
75(8 - y) + 35y = 400
600 - 75y + 35y = 400
600 -40y = 400
600 - 400 = 40y
200 = 40y
∴ 40y = 200
y = 200/40
y = 5
Substitute the value of y into equation (3)
x = 8 - y
x = 8 - 5
x = 3
∴ x = 3 and y = 5
Hence, 3 dogs and 5 cats were adopted out on Christmas eve.
What is the best description of slope (m) in a word problem?
The total at a certain time
The starting point
The rate of change
The amount of time
Answer:
Word problems with linear equations (that is, with straight-line models) almost always work this way: the slope is the rate of change, and the y-intercept is the starting value.

what is the probability of drawing a 9 or diamond from a standard deck of cards?
Explanation:
In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).
Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 9.
With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).
Our denominator here is 52 - the number of cards from which we can pull 1.
Our numerator is both all the diamonds, 13 cards, and all the nines, 4 cards, but we need to subtract 1 to account for the double counting of the 9 of diamonds.
In all we get:
13+4 - 1/52 =
≈ 16/52
=4/13
Answer: 0.3077
Probabilities are used to determine how likely an event is, to happen. The probability of drawing a 9 or diamond is: 4/13
In a standard deck of cards, we have:
[tex]n = 52[/tex] --- There are 52 cards in total
[tex]n(9) = 4[/tex] ---- Cards with number 9 are 4
[tex]n(Diamond) =13[/tex] ---- there are 13 diamonds
[tex]n(9\ n\ Diamond) = 1[/tex] ---- Diamond cards with number 9
The probability of drawing a 9 or diamond is:
[tex]P(9\ or\ Diamond) = P(9) + P(Diamond) - P(9\ n\ Diamond)[/tex]
So, we have:
[tex]P(9\ or\ Diamond) = \frac{n(9)}{n} + \frac{P(Diamond)}{n} - \frac{n(9\ n\ Diamond)}{n}[/tex]
This gives:
[tex]P(9\ or\ Diamond) = \frac{4}{52} + \frac{13}{52} - \frac{1}{52}[/tex]
Take LCM
[tex]P(9\ or\ Diamond) = \frac{4+13-1}{52}[/tex]
[tex]P(9\ or\ Diamond) = \frac{16}{52}[/tex]
Simplify
[tex]P(9\ or\ Diamond) = \frac{4}{13}[/tex]
Hence, the probability of drawing a 9 or diamond is: 4/13
