Answer:
1.57
Step-by-step explanation:
Circumference=2pi r
=2x3.14x.25
=1.57
Answer:
C = .5 pi inches
If we approximate pi by 3.14
C =1.57 inches
If we approximate pi by the pi button
C =1.570796327 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2* pi *r
C = 2 * pi * .25
C = .5 pi
If we approximate pi by 3.14
C =1.57 inches
If we approximate pi by the pi button
C =1.570796327 inches
The radius of a circle is three units. What is the diameter of the circle?
Answer:
6 units
Step-by-step explanation:
3x2=6
Answer: 6 units
Step-by-step explanation: The diameter of a circle which is a cord that passes through the center is always 2 times the radius.
So if we know that the radius of pour circle is 3 units,
we can simply multiply 2 by 3 to get 6 units.
So the diameter is 6 units.

Answer: $ 82,531.59.
Step-by-step explanation:
Formula to calculate the accumulated amount compounded daily:
[tex]A=P(1+\dfrac{r}{365})^{t}[/tex]
,where P=principal amount, t=time ( in days ), r =rate of interest.
Given: P= $51,123.21
r = [tex]2\dfrac{3}{8}\%=\dfrac{19}{8}\%=0.02375[/tex]
t= 20 years 2 months
[tex]= 20(365)+\dfrac{2}{12}(365)\\\\= 7360.83[/tex] [1 year = 365 days, 1 year = 12 months]
Substitute all values in the formula, we get
[tex]A=(51123.21)(1+\dfrac{0.02375}{365})^{7360.83}\\\\\approx82531.59[/tex]
hence, future value = $ 82,531.59.

in a survey of 420 people, 85% said they drink coffee. of these, 1/3 said they drink their coffee black. how many of the people surveyed drink it black?
Answer:
A.) 119
420 * 0.85 is 357 and 357 * 1/3 is 119
Hope this helps ^^
Answer:
119
Step-by-step explanation:
The total number of people who had taken the survey is 420 wich is equivalent to 100%.
The percentage of people who drink coffee is 85%.
●●●●●●●●●●●●●●●●●●●●●●●●
Let x be the number of people drinking coffee
● 420 => 100%
● x => 85%
These values are proportional so we can cross-multiply them
● x*100 = 420*85
● x = (420*85)÷100
● x = 357
The number of people who drink coffee is 357.
■■■■■■■■■■■■■■■■■■■■■■■■■
Let y be the number of people who drink black coffee.
y is 1/3 of 357 since people who drink black coffee represent the third of the total number of people drinking coffee in general.
● To get y multiply 1/3 by the total number of people drinking coffee (357)
●y = (1/3)*357
● y = 119
119 is the number of people who drink black coffee
Brainliest for whoever answers fully! Part A: Using the graph above, create a system of inequalities that only contains points C and F in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points) Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A. (3 points) Part C: Chickens can only be raised in the area defined by y > −4x + 3. Explain how you can identify farms in which chickens can be raised. (2 points)
Answer:
Hope this helps
Step-by-step explanation:
For part A, we want two inequalities that have F and D as solutions, but none of the other points. The easiest way to do this is construct two lines that pass through the origin, and then figure out which way the inequalities need to face based on the points we want to include. Our lines will be:
The first line intersects F and the second line intersects D, so we need to figure out which way to point the inequalities so both include the point they do not intersect:
So our system is:
Part B: To verify, plug in the x and y values for D and F and verify that it creates true statements in the system.
Part C: You can plug in the different x, y values for the points. The points which create true statements identify farms where chickens can be raised, while those which create false statements cannot raise chickens.

An amusement park sells adult tickets and children’s tickets, with adults tickets costing $5 and children’s tickets costing $3. If Ed bought 15 tickets and spent a total of $57, how many children’s tickets did he buy? 3 5 6 9
Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)

(a) Solve the system of linear equations:
x + y = 14
X-y=6
Answer:
x=10,y =4
Step-by-step explanation:
x + y = 14
X-y=6
Add the two equations together to eliminate y
x + y = 14
X-y=6
-----------------------
2x +0y = 20
Divide by 2
2x/2 =20/2
x = 10
Then find y
x+y = 14
10+y =14
Subtract 10 from each side
10+y-10=14-10
y =4
Answer:
x = 10, y = 4
Step-by-step explanation:
One way of doing this is by doing the substitution method
To do this you first need to put x on one side (x = y + 6)
Now where there is an x in the first equation you put that instead
(y + 6) + y = 14
After this, you solve for y (y = 4)
Lastly, you put the 4 where there is a y and then solve for x
x - 4 = 6
x = 10

I don’t want the answer to this just how to work it out. The required staff to student ratio is 2:15. If 340 people attended the excursion, how many teachers were there?? Thanks
Answer:
40 teachers.
Step-by-step explanation:
The required staff to student ratio is 2:15340 people attended the excursion.We are to find the number of teachers (staff) who attended the excursion).
For every 2 staff, there are 15 students
The number of teachers who attended the excursion is [tex]\frac{2}{17}[/tex] × 340 = 40 teachers
The number of students who attended the excursion is [tex]\frac{15}{17}[/tex] × 340 = 300
Leo had a $30 gift card to use at a coffee shop. He used the entire balance to buy regular-sized coffees, which cost $2, and large coffees, which cost $3. If he bought 13 coffees in total, how many large coffees did he buy? 2 3 4 9
Answer:
4 Large coffees
Step-by-step explanation:
4 X $3.00 = $12.00
9 x $2.00 = $18.00
$18.00 (9 small coffees) + $12.00 (4 Large Coffees ) = $30.00

Anna is saving to buy some souvenirs on a family vacation. She has already saved $125, and she saves another $2 from her allowance every day. Formulate and then graph the equation that models the total amount Anna saves, y, in terms of the number of days she adds to her savings, X.
Answer:
y = 2x + 125
Step-by-step explanation:
y = mx + c
c in this problem is $125.
It is the amount of money she has already saved, that is not going to change, so this is the y intercept.
She saves $2 every day, with the number of days being x.
So she saves $2 × x = 2x
2x is the gradient.
On your graph, your straight lien should run through 125 on the y-axis.
The line should have a gradient, or slope, of 2x.
Make sure to plot carefully, looking at the scale of the graph.
The equation is that the total amount Anna saves will be y = 2x + 125. And the graph of the line is drawn below.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Anna is saving to get a few keepsakes on a family excursion. She has previously saved $125, and she saves another $2 from her remittance consistently.
Let 'x' be the number of days and 'y' be the total cost. Then the equation is given as,
y = 2x + 125
The equation is that the total amount Anna saves will be y = 2x + 125. And the graph of the line is drawn below.

The bending of a bean varies directly as its mas. A beam is bent 20mm by a mass 0f 40kg. how much will the beam bend with a mass of 100kg?
Answer:
The beam will bend by 50 mm with a mass of 100kg?
Step-by-step explanation:
The first step in solving the problem of direct variation is setting up the relation mathematically.
We can do this as follows:
The bending of the beam varies directly as its mass.
[tex]20 \alpha 40kg[/tex]
[tex]\alpha[/tex] here is the symbol representing direct variation. To remove this and replace it with an equality sign, we have to introduce a constant of proportionality, k
[tex]20 = k \times 40[/tex]
k = 20 /40 = 0.5
We can now use this to find the distance the beam will bend with a mass of 100kg?
This will be
[tex]Bending = 0.5 \times 100 =50mm[/tex]
There fore, the beam will bend by 50 mm with a mass of 100kg?
