Answer: 89.1

Step-by-step explanation: Firstly, for the square, you would multiply 8 by 8 which would result in 64. That is your first addend. Next, to find the area of the semicircle, you find the area of a whole circle, then divide by two. In this case, the area formula would be (pi)r^2. So, the radius would be 4, and in he formula that would end up with the answer being 50.24. Then, you divide by two. 25.1 (rounded to tenths) + 64 = 89.1.

Hope this helped!!

Answer:

x=11.333333

Step-by-step explanation:

1.5+.75x=10

subtract 1.5 from both sides.

1.5+.75x-1.5=10-1.5

.75x=8.5

divide .75 on both sides

.75x.75=x

8.5/.75=11.333333

Answer:

Using the formula for the distance between two points, which is generated using coordinates and absolute value, we find that the distance between these two points is of 9 units.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

This formula is generated using coordinates and absolute value.

In this question:

(3,-7) and (3,2). So

[tex]D = \sqrt{(3-3)^2+(2-(7))^2} = \sqrt{81} = 9[/tex]

The distance between these two points is of 9 units.

Answer:

there does not seem like a picture so I dont know the answer

Answer:

Quarters = 10

Dimes = 15

Step-by-step explanation:

d = number of dimes, q = number of quarters

d + q = 25 is the equation for number of coins

0.1d + 0.25q = 4 is the equation for value of coins

First, solve for d in terms of q:

d + q = 25

d = 25 - q

Then substitute that into the other equation:

0.1(25 - q) + 0.25q = 4

2.5 - 0.1q + 0.25q = 4

0.15q = 1.5

q = 10

And back to d = 25 - q, d = 25 - 10 = 15

Check the math:

0.1(15) + 10(0.25) = 1.5 + 2.5 = 4

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

a. c = 5.5n

b. Continuous

c. $33

Step-by-step explanation:

A store sells assorted nuts for $5.50 per pound.

a) Write a function in equation form to represent the total cost (c) of any number of pounds of nuts (n)

For every n, 5.5 is added to c. Thus, c = 5.5n

b) Will the graph of this function be continuous or discrete?

Continuous domains are ones that continue on in between intervals. For example, the height of someone would be continuous, because it could, for example, be between 50 inches and 70 inches. On the other hand, discrete domains are ones that can only be a set of given numbers. An example would be how much food you need to feed to a number of cats (for example, each cat needs to eat 0.5 pounds of food). Because you cannot have half a cat, the domain needs to have whole numbers.

Because you can buy 0.5 or 0.2 (or any amount of nuts), the domain is continuous.

c) What would the total cost be for 6 pounds of nuts?

Using the function from a), we know that the cost is 5.5n, where n is the amount of nuts you buy, in pounds. So, plug in "6"

5.5n = 5.5 * 6 = 33

Cost is $33

1. Isoceles and 40°(Acute)

2. Scalene and 110°(Obtuse)

3. Equilateral and 60°(Acute)

4. Isoceles and 45°(Right)

Answer:

8 + 56 = 64

Step-by-step explanation:

Even if they dont give the third given length you can obviously see its a cube so all lengths are equal so multiply 2 by itself 3 times to get 8. Then the left figure will be multiplied like this: 7 x 2 x 4 = 56. Then you add them up to get 64.

Answer:

There are five different ways to assign teams.

Step-by-step explanation:

To make the correct assignment we must bear in mind that there are two variables or students that will always be static, which are Aishu and Jeremi, so the other two students could be assigned with each of them finally 5 teams can be successfully formed.

First team:       (Aishu-Xiaoying), (Jeremy), (Daniel)

Second team:  (Aishu), (jeremy-xiaoying),(Daniel)

Third Team:     (Aishu), (Jeremy), (Daniel-Xiaoying)

Fourth Team:   (Aishu-Daniel), (Jeremy), (Xiaoying)

Fifth Team:      (Aishu), (Jeremy-Daniel), (Xiaoying)
