In a bag of gumballs, 50% of the gumballs are blue. There are 40 blue gumballs in the bag. How many total gumballs are in the bag?

80
58
200
42

Answers

Answer 1

Answer:

80

Step-by-step explanation:

40*2=80

Answer 2

Answer:

It is 80.

Step-by-step explanation:

50% is half and there are 40 blue gumballs in the bag. If you wanted to know the total, you would double 40 because 40 is 50% of the bag, so you are just adding half of it in to get the whole. When you double it, you get 80.

Answers

Answer:

15.1657508881 or 15.17

Step-by-step explanation:

I believe you are supposed to use the hypotenuse of a right triangle equation

a2+b2=c2

Let's begin! 27 feet is the hypotenuse (the longest part of a right triangle)(c)

so 7*7 is equal to 49

and 27*27 is equal to 279

Now you put the numbers back into the equation

49+b2=279, Now let's solve for b

279-49=230 b2=230

230 squared is 15.1657508881

Hope this makes sense!

E $2,500,000


Based on the data, should Jasper use the mean or the median to make an inference about the house values in his neighborhood? (10 points)
Group of answer choices

He should use the mean because it is in the center of the data.

He should use the median because it is in the center of the data.

He should use the median because there is an outlier that affects the mean.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation is:

7x - 5y = 28

From the above equation:

y = mx + c

On comparing:

y = (7/5)x - 28/5

m = 7/5

c = -28/5

After plotting the graph of the equation:

From the graph:

B. (−1, −7)

D. (−6, −14) are the ordered pairs in the form (x, y) that are solutions to the equation.

Thus, options B. (−1, −7) and D. (−6, −14) are correct which are the solutions to the equation.

At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75. They decide to leave a 20% tip based on the total bill before tax. What is the total value of the tip they will leave?

Answers

Answer:

leave a $3.25 tip

Step-by-step explanation:

All decide to leave a 20% tip based on the total bill before tax.

Total value of tip is $5.85

Given :

At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75.

Total bill = appetizer cost for three persons + entree fee

Total bill =[tex]6.50 (3)+9.75=29.25[/tex]

So total bill is $29.25

Tip left is 20% of the total bill

Now we find the total value of tip

Total value of tip =20% times 29.25

[tex]Total \; value =0.20 \cdot 29.25=5.85[/tex]

The total value of tip is [tex]5.85[/tex] dollars

Step-by-step explanation:

A 2-column table with 3 rows. Column 1 is labeled x with entries 16, 32, 48. Column 2 is labeled y with entries 1, 2, 4.

No, as x= 4 ⇒ y =64 not 48

A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 5, 6. Column 2 is labeled y with entries 5, 20, 30.

No, as x = 5 ⇒ y = 25 not 20

Yes, as 2*7 = 14, 4*7= 28, 6*7= 42

A 2-column table with 3 rows. Column 1 is labeled x with entries 0, 1, 3. Column 2 is labeled y with entries 25, 70, 90.

In order to find the solution, You would first line line the equation up. then, you would subtract -200 by 15. The answer would be -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive. If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative.

Included: Negative, positive, equivalent.
