Fernando spent $20 of his $50 weekly allowance on snacks. What percent of his weekly allowance did he spend snacks?

**Answer:**

is the answer of 50 and spend 20 you have 30 left

**Answer:**

40%

**Step-by-step explanation:**

A good way to remember how to do percentages is starting with 10% of overall.

Overall, 10% of the $50 would be $5

you just move the decimal from $50.00 to $5.00

moving it to the left once, for ten percent

theres $20 so thats the 10x2

20 goes into 100, 5 times ...

It just so happens in this scenario, its 20% just like the $20 ... doesnt always happen like this.

How is the domain of a function related to the numbers in the sequence?

How is the range of the function related to the numbers in the sequence?

**Answer:**

A sequence is a function whose domain is the set of natural numbers or a subset of the natural numbers. We usually use the symbol an to represent a sequence, where n is a natural number and an is the value of the function on n.

Julia loves collecting baskets. Every month she adds two new baskets to her collection. In the month of March she has 60 baskets. She’s worried she will soon run out of room in her apartment to keep her baskets. Write an equation that represents the percent of change of her basket collection from the beginning of the year to the end of the year, then solve.

The linear function that represents the amount of baskets in the xth month of the year is given as follows:

The percentage of her collection that she needs to get rid of is of 3.85%.

Linear Function:-

The definition of a linear function is:

y = b + mx

In which the parameters of the equation are given as follows:

•b is the value of y when x=0

•m is the rate of change for each unit of x

Every month she adds 2 new baskets to her collection, hence the slope is of : m = 2

Then: y = b + 2x

From the March amount, when x = 3, y = 60, hence the intercept b is given as follows:

60 = b + 6

b = 54

Hence the equation is: y = 54 + 2x

At the end of the year (12 months) the amount of baskets that she will have is of:

y = 54 + 2 × 12 = 78

Hence, she has to get rid of 3 baskets, as 78 - 75 = 3, and the percentage is of:

p = 3/78 × 100% = 3.85%.

**Answer: **

**Step-by-step explanation: The linear function that represents the number of baskets in the month of the year is given as follows:**

**The percentage of her collection that she needs to get rid of is of 3.85%.**

1 x 7 - 13 x 56 divided by 7 -5 x 500 is what?

**Answer: -2597**

**Step-by-step explanation: First, you multiply 1 x 7 to get 7, then subtract 13 from that, and multiply that by 56. Then you find what 7 -5 x 500 is, and divide it by the first part you got, to ger -2597. I'm sorry If I'm wrong .**

**Answer:**

-2597

**Step-by-step explanation:**

Using PEMDAS, M would be multiplying so you you multiy 1x7 then times 56 then S is for subtraction so then you subtract 13, save that first set (1x7-13x56) to the side and now lets do the other set (7-5x500) first you would multiply it by the 500 and you get 3,500 then subtract it now get your two answers and divide it, then youll get -2597

3 plus 4 times a number is 5 times the number. What is the number?

Because first the “ number” is X so then the problem would be turned into 3 + 4x = 5x and you need to get all the numbers on one side and the X’s on the other side

Distance between points (-1.5, 1.25) and (-1.5, -0.75) is 2

The vertical **distance **between the **points **A and B are D = 2 units

Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )

The **distance **from A to B is the same as the distance from B to A

**Distance **between two **points **is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

This formula is used to find the **distance **between any two points on a coordinate plane or x-y plane

Given data ,

Let the **distance **between 2 points be represented as D

Now , let the first point be A ( -1.5 , 1.25 )

Let the second point be B ( -1.5 , -0.75 )

The **distance **D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

And , the vertical **distance **between A and B = |y-coordinate of A - y-coordinate of B|

So , the value of D = |1.25 - (-0.75)|

D = 2 units

Hence , the vertical **distance **is D = 2 units

Sam’s Soups is open 6 days a week, 76 hours in all. Its hours are the same every day, except on Saturday and Sunday. On those days, it is open 2 hours longer. How long is Sam’s Soups open on Sunday? Use an equation to solve.

Answer:

14 hours

Step-by-step explanation:

Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday.

Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:

4x + 2(x + 2)= 76

4x+ 2x + 4 = 76

6x=72

x = 12

Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x

+ 2. Thus, that is 12 + 2 = 14 hours.

14 hours

Step-by-step explanation:

Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday.

Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:

4x + 2(x + 2)= 76

4x+ 2x + 4 = 76

6x=72

x = 12

Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x

+ 2. Thus, that is 12 + 2 = 14 hours.

**Answer:**

**i think it is 45.70**

**Step-by-step explanation:**

**Answer:**

$48.55

**Step-by-step explanation:**

**Equation: **

17% = 0.17

Why? *The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.*

0.17 × (Britain Value Including Tax) 58.50 = 9.945 **to be exact but I rounded it up to 9.95 for easier use **

58.50 - 9.95 = 48.55

The answer is 8 so its a direct proportion

I think...

The **constant **of **Proportionality **is 8.

If the **ratio **of one variable to the other is constant, then there is a proportional **relationship **between the **two variables**. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also **express **it as x is to y at times.

Given:

**Total **Baseball **Caps**= 30

Total **amount **of Cap= $240

let the **number **of caps sold be c.

Then, the **equation **is

30 c= 240

and, c= 240/30

c= 8
