Answer:

c.15L +55≥205

Step-by-step explanation:

More than means greater than or equal to and is represented by the symbol

≥

Michael earned $15 per lawn he mowed this month plus an additional $55 in tips. He earned more than $205 in total.

Hence,

$55 + $15 × L ≥ $205

55 + 15L ≥ 205

Therefore, the inequality that best represents the situation, where L represents the number of lawns Michael mowed this month is

Option c.15L +55 ≥ 205

Answer:

The distribution peaks at 5. This is the only right answer

Step-by-step explanation:

The distribution is NOT symmetrical- the distribution is skewed to right. If you divide the plot in half (make a vertical line going between 3 and 4 in your head) you'll that both sides are not the same

The data set has a range of 3- 5 minus 2 equals 3

The distribution is skewed to the right, not the left (most of the data is on the right side of the plot aka 4 and 5. this goes back to the distribution not being symmetrical)

Answer:

The distribution peaks at 5.

The distribution is symmetrical.

The data set has a range of 5.

Answer:

8.40

Step-by-step explanation: This means the cost of the item to you is $8.4. You will pay $8.4 for a item with original price of $12 when discounted 30%. In this example, if you buy an item at $12 with 30% discount, you will pay 12 - 3.6 = 8.4 dollars.

Answer:

The new total will be $8.40.

Step-by-step explanation:

The 30% off discount gives you $3.60 off of your purchase.

Answer:

m∠FAN = 80°

Step-by-step explanation:

Area of a sector is given by the expression,

Area of the sector = [tex]\frac{\theta}{360}\pi r^{2}[/tex]

Here, θ = central angle subtended by the arc

r = Radius of the circle

By substituting the values from the question,

288π = [tex]\frac{\theta}{360}(\pi )(36)^2[/tex]

θ = [tex]\frac{288\pi }{1296\pi }\times 360[/tex]

θ = 80°

Therefore, m∠FAN = 80° will be the answer.

Answer:

Area of the image rectangle = 4(Area of the original rectangle)

Step-by-step explanation:

Length of the rectangle given in the graph = 4 units

Width of the rectangle = 2 units

Area of the rectangle = Length × Width

                                    = 4 × 2

                                    = 8  square units

Since, scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]

2 = [tex]\frac{\text{Length of the image}}{\text{Length of the original}}[/tex]

Length of the image rectangle = 2(4)

                                                   = 8 units

Similarly, width of the image rectangle = 2(2)

                                                     = 4 units

Area of the image rectangle = 8 × 4

Area of the image = Area of the original × 4

Area of the image = 4(Area of the original)

Area of the image rectangle = 4(Area of the original rectangle)

Answer:

No, she cannot fit all the 51 boxes in the storage container.

Step-by-step explanation:

The storage container is shaped like a rectangular prism , hence,

The formula for the volume of the storage container = Length × Width × Height

We are given the dimensions of the Storage container as

3 feet long = Length

2 feet wide = Width

8 ft tall = Height

Hence, Volume = 3 ft × 2 ft × 8 ft

= 48 ft³

We are told that 51 boxes , each as volume of 1 cubic foot

Hence, the total volume of the boxes = 51 × 1 cubic foot = 51 ft³

From the calculations above, we can conclude that she cannot fit all the 51 boxes in the container.

for the trapezoid/trapezium

the formula for finding the area of a trapezoid is A=(a+b)/2*h, and if you didnt know, a and b are always parallel.

for the parallelogram

it will always be b*h, this one is pretty easy to remember, also parallelograms include squares, rectangles, and anything with 4 sides.

the example

lets just say that we are missing a, which is the top one. now we have to fill in the missing little bit marked by a green square. this particular trapezoid is symmetrical, so we dont have to find the other side, but if it wasn´t, then you have to find the other side with the Pythagorean thoream. That is what we are going to do now. We have a and c and we need to find b in a²+b²=c², so plug in our values for a and c

(10)²+b²=(13)²

100+b²=169

now just isolate b and solve

b²=69

how to undo a square is by taking the square root of the other side of the equation

sqrt(69) is about 8.3

Answer:

  A.  y = 0.45x +7

Step-by-step explanation:

When the y/x come out different, it means the relation is not a proportion. So, the "rate of change" need to be computed from ∆y/∆x, not y/x.

∆y is the difference between two y-values. If we use the first two columns of the table, we have ...

  ∆y = 6.2 -5.4 = 0.8

  ∆x = 3 - 1 = 2

Then the rate of change shown in the table is ∆y/∆x = 0.8/2 = 0.4.

__

For the equations, the rate of change is the coefficient of x. Those are ...

  0.45, -1/2, 0.2, 1/10

If we were to put these rates of change in order on a number line, that order would be ...

  -1/2 < 1/10 < 0.2 < 0.4 < 0.45

A: y = 0.45x+7 has a greater rate of change than shown in the table.

Answer:

1. 20 half of 20 is 10(new radius),

10^10 = 100

100 x 3.14 = 314

314 divided by 2 = 157

2. 8 x 8 = 64, 64 divided by 2 ( x 1/2) = 32

half of 8 is 4(new radius)

4 ^4 = 16, 16 x 3.14 = 50.24

50.24 divided by 2 = 25.12

25.12 + 32 = 57.12

3. Half of 7 is 3.5(new radius)

Just find the area of a full circle since two semi circles make a full circle.

3.5^2 = 12.25

12.25 x 3.14 = 38.465,

21 x 7 = 147

147 + 38.465 = 185.465

4. Half of 6 is 3(new radius)

3^3 = 9

9 x 3.14 = 28.26, 28.26 divided by 2 = 14.13

11 x 6 = 66, 66 divided by 2 (x 1/2) = 33

14.13 + 33 = 47.13

5. 81 divided by 4 = 20.25

half of 20.25 is 10.125(new radius)

10.125 x 2 x 3.14 = 63.585 rounded = 63.59

Answer:

11:40 in the morning

Step-by-step explanation:

Given that for every 550 m, Bella the eagle flies, she is blown back fifty meters by the wind. Her nest is 5 km and she flies 550 m in 1 minutes.

Therefore for Bella to reach her nest which is 5 km (5000 m) away, the required distance (d) she needs to travel is:

d - (d/550)50 = 5000

d - 50d/550 = 5000

500d / 550 = 5000

d = (550 * 5000) / 500 = 5500

d = 5500 m = 5.5 km

speed = distance / time = 550 m / 1 minutes = 550 meters per minute

The time t required to cover 5500 m is:

speed = distance / time

550 meters per minute = 5500 m / t

t =  5500 m  / 550 meters per minute

t = 10 minutes

If Bella lives at 11:30 am in the morning and then travels for 10 minutes to reach her nest, the time Bella will reach her nest is 11:40 am

Answer:

Yes they are wrong, rational & irrational ones down below.

Step-by-step explanation:

So, lets start this by asking, what is a rational and irrational number?

Rational numbers are literally any numbers that arent pi, e, or other symbols, as well as square roots.

Irrational numbers are exactly the opposite, being the numbers that are symbols, including square roots.

Note that the symbols listed above such as pi are values that are neverending.

Now, using what we know of rational and irrational numbers, let see which answers are rational and which are not.

So, we start off with:

-13/3

I do not see a square root.

I do not see a symbol such as pi either.

It is not a ever going number.(number that continues infinitly)

So -13/3 is a rational number.

Next we have [tex]\sqrt{37}[/tex]

immediatly we tell it has a square root.

So [tex]\sqrt{37}[/tex] is a irrational number.

Next we have 0.1234

This is not a every going number.

There isnt a square root.

And it isnt a symbol.

So 0.1234 is a rational number.

Next we have [tex]-\sqrt{100}[/tex]

Again, we can immediatly know it has a square root.

So  [tex]-\sqrt{100}[/tex] is a irrational number.

Next we have -77

This is not every going.

It doesnt have a square root.

It doesnt have a symbol.

So -77 is a rational number.

Lastly we have   [tex]-\sqrt{12}[/tex]

Like the other ones, we can imediatly tell it has a square root.

So [tex]-\sqrt{12}[/tex] is a irrational number.

Bascially, to answer further questions, here is the criteria for a number being rational:

If one of these criterias are not met, then you know its a irrational number.
