Find the length of the arc
A.8 pie ft
B.32 pie ft
C.64 pie ft
D. 361 pie/ 12 ft

Answer:

Measured and Counted.

Step-by-step explanation:

Continuous data are usually “Measured”, but discrete data are usually “Counted”.

The continuous data are the data that can be measured, for example, Height of children, time in the race, length of leaf, etc. In this case, the data is taken within the range. While the discrete data is the data that can be counted. For example, the number of employees in the office, the number of students in the school, the result of rolling dice, etc. In this case, the data is a fixed number. Accordingly, the continuous data is measurable and discrete data is countable.

Answer: 312

Step-by-step explanation:

First you start with 50 dollar

then multiply 12.50 by 12

then multiply 14.00 by 8

last add everying thing up; 50+150+112

and you get 312 dollars

aka: $312.00

Answer:  The distance is 30

Step-by-step explanation:

To find the distance between the two points,find the difference between the x and y values, square them and add them to find their square root.

10 - (-14) = 24

-16 - 2=   -18

24^2 + 18^2 = d^2  where d is the distance

576 + 324 = d^2  

900 =d^2

d = [tex]\sqrt{900}[/tex]

d= 30

Answer:

d=30

Step-by-step explanation:

distance between 2 points: d

d=√(x2-x1)²+(y2-y1)²     (-16,10) and (2,-14)

d=√(2-(-16)²+(-14-10)²

d=√18²+(-24)²

d=√324+576

d=√900

d=30

Answer:

150 g

Step-by-step explanation:

The 2 part of the ratio represents 60 g , thus

60 g ÷ 2 = 30 g ← value of 1 part of the ratio, then

5 parts = 5 × 30 g = 150 g ← amount of flour required

Answer:

≤

Step-by-step explanation:

First we solve 5(x + 2) ≥ 2(x + 8).

5x + 10 ≥ 2x + 16

3x ≥ 6

x ≥ 2.

Now we place an equal sign into the box:

4(x - 6) = 2(x - 10)

4x - 24 = 2x - 20

2x = 4

x = 2.

For the solution to only have 1 value, the solution must be x = 2.

Therefore we must have x ≥ 2 and x ≤ 2.

Answer:

  you're nearly there

Step-by-step explanation:

You have obviously determined the correct entry in the top box of each pair. What you seem to have failed to observe is that the bottom box in each pair needs exactly the same entry as the top box.

_____

You figure this out by looking at the stuff that is outside the box. The numbers and symbols for the second box show how the function indicated outside the first box is evaluated. That is f(x) at the top becomes 4x at the bottom, where x (in this case) is x/4 for both.

area of triangle formula = ½ × B × H

28in2 = ½ × B × (8)

28in2 = 4 × B

28 ÷ 4 = B

Therefore, length of base = 7 inches

Answer:

1800 people were at the concert.

Hello there! :D

Its math time!!

Alright, let's write out all the percentages.

60%= adults

25%= boys

There are thirty girls.

We can find out what percentage of the people there are girls by adding the percentages of the adults and boys and subtracting that from 100.

60+25= 85

100-85=15

So, 15% of the audience are girls. That is equal to 30 people.

I also know that 60 is divisible by 15 and 4. So, if we multiply 30 by 4 we can find out how many adults are at the concert.

30*4= 120 adults

We can also take 15 and divide it by 3 (as well as 30)  so we can find out how many people there are for 5% of the concert. That will make it easier to find out how many boys there are.

15/3= 5%

30/3=10

Now we just need to know how many fives go into 25, which is 5.

5*10= 50

Add that to the number of adults and girls:

50+120+30= 200 people

There are 200 people at the concert!

I hope this helped you and you have a wonderful day,

Answer:

[tex]u<-1\text{ or } u>2[/tex]

Step-by-step explanation:

So we have the equation:

[tex]-3|2-4u|+5<-13[/tex]

First, subtract -5 from both sides:

[tex]-3|2-4u|<-18[/tex]

Divide both sides by -3. Since we are dividing by a negative, we will flip the sign:

[tex]|2-4u|>6[/tex]

Definition of absolute value:

[tex]2-4u>6\text{ or } 2-4u<-6[/tex]

Note that we flip the sign on the right because we multiplied 6 by a negative.

On both the left and right, subtract 2:

[tex]-4u>4\text{ or } -4u<-8[/tex]

Divide both equations by -4. Since we're dividing by a negative, flip the signs:

[tex]u<-1\text{ or } u>2[/tex]

So, our final solution is:

[tex]u<-1\text{ or } u>2[/tex]

And we're done!

Answer:

x = 45

45 years old

Step-by-step explanation:

x + 3 = 4(x - 33)

x + 3 = 4x - 132

x - 4x = - 132 - 3

-3x = -135

x = -135/-3

x = 45

Answer: 3x-x+2=4

Step-by-step explanation:

Answer:

The correct answer i would think would be A. 1 + -1= 0

Step-by-step explanation:

Given :

The number of goals they scored over the first 7 games of the season are :

3, 7, 3, 0, 5, 8, 2 .

To Find :

The mean number of goals the Strikers scored each game .

Solution :

We know , mean of numbers is given by :

[tex]M=\dfrac{\text{Sum of all numbers}}{\text{Total numbers}}\\\\M = \dfrac{3+7+3+0+5+8+2}{7}\\\\M=\dfrac{28}{7}\\\\M=4[/tex]

Therefore , the mean number of goals the Strikers scored each game is 4 .

Hence , this is the required solution .

Answer:

x = 135°

Step-by-step explanation:

Sum of interior angles of a pentagon is 540°

x + 80 + 110 + 95 + 120 = 540

--> x = 540 - 80 - 110 - 95 - 120 = 135

Answer:

Nick get = $10

Pam get = $28.25

Step-by-step explanation:

Given:

Total amount paid = $38.25

Nick work = 1 hour 5 minutes = 1.0833 hr

Pam work = 3 hour

Find:

Amount they get

Computation:

Assume each get x in 1 hour

So,

3x + 1.0833x = 38.25

4.0833x = 38.25

x = 9.3674

Nick get = 1.0833(9.3674) = 10.14 = $10

Pam get = $38.25 - $10 = $28.25

Answer:  see below

Step-by-step explanation:

Write each equation in y = mx + b format where m is the slope and b is the y-intercept.

Left side: -4 ≤ x < -1

If you continue the line through the y-axis it will pass through (0, 4) --> b = 4

The rise over run is -1 over 1 --> m = -1

y = (-1)x + (4)   -->    y = -x + 4

Right side: -1 < x < 4

The line passes through (0,0) --> b = 0.

The rise over run is -1 over 1 --> m = -1

y = (-1)x + (0)    -->    y = -x

[tex]\large\boxed{f(x)=\bigg\{\begin{array}{ll} -x+4&;-4\leq x<-1\\ -x&;-1<x<4 \end{array}}[/tex]

Answer:

Step-by-step explanation:

d = number of dimes

2.80 = 0.1d + 0.25 (d + 8 )

2.80 = 0.1d + 0.25d + 2            Combine like terms

2.80 = 0.35d + 2                       Subtract 2 from both sides

0.80 = 0.35d                             Divide both sides by 0.35

d ≈ 2.29

No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.

Answer:

2 3/4 gallons in each container

Step-by-step explanation:

Gallons of water = 11

Containers = 4

Larry pours 11 gallons of water equally into 4 containers

Gallons of water in each container = Total gallons of water / number of containers

= 11 / 4

= 2 3/4

There are 2 3/4 gallons of water in each containers

The equation is

Gallons of water in each container = Total gallons of water / number of containers

Answer:

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

Step-by-step explanation:

plz forgive me if my answer is wrong

Domain = looking for the very far left value and the very far right value on the x-axis, and only x-axis, so the farthest left x-axis value and the farthest right x-axis value.

Range = very bottom y-value, and very top y-value

In both cases, if the arrows extend forever then that means you could have the value of infinity.

Answer:

81 miles

Step-by-step explanation:

From the question 7/10 of the trip has been said to be downhill. It therefore means that 3/10 is not downhill.

Miles = 270

Downhill = 7/10

Not downhill = 3/10

Now we have To calculate Miles that are not downhill (uphill)

But first I calculated for the number of downhill miles

270x7/10

Downhill = 189 miles

To get the number of not downhill miles

I subtracted 189 from the total number of miles on the question.

270 - 189

= 81 Miles.

Therefore 81 Miles of the trip are not downhill.
