The radius of a circle is 7 millimeters. What is the circle's area?
r=7 mm
Use 3.14 for a.
Answer:
153.86
Step-by-step explanation:
formula - A = π × r2
3.14 x 7^2
= 153.86
Answer: 106.76 Millimeters
Step-by-step explanation:
The radius is 17 millimeters. Replace r by 17 in the formula.
C = 2r
≈2 x 3.14 x 17
≈106.76
The circumference is about 106.76 millimeters.

The rate, r, at which you drive a car is related to the distance, d, and time, t, in the
equation
d
r =
If you increase the distance and keep your rate constant (stays the same), what
happens to your time?
A.Your time will decrease
B.Not enough information to tell
C.Your time will increase
D.Your time will stay the same
Answer:
C. Your time will increase
Step-by-step explanation:
Since r= d/t, then if you increase d, t will decrease since r is staying the same

Make each expression a true statement
Answer:
( d / c ) < ( a / d )
( b / d ) < ( a / d )
( d / a ) < ( a / d )
Step-by-step explanation:
For this problem, we need to consider the given information that a > b > c > d > 0. Note that a is the greatest number and that d is the least number.
Given this fact, we can create a fraction that will result in a maximum value by simply doing the following:
a / d
The reason the fraction ( a / d ) results in a maximum, is because of the given information where a is the furthest from 0, and d is the closest to 0. Therefore, we can say that no other combination will result in a value greater than ( a / d).
So in the three given statements, we have different combinations of fractions being compared to our maximum value fraction. Our maximum value fraction ( a / d ) will always be greater than any other combination.
Thus, we will choose the sign that makes ( a / d ) greater than the other choice fractions.
Cheers.
HURRY NEED ANSWER ASAP NOW PRONTO Simplify (−8.5)(−5)( −2). 850 85 −85 −850
Answer:
−85
Step-by-step explanation:
Let us restate the problem once more;
(-8.5)(-5)(-2) = ?
In mathematical problems as such, it is best to apply the order of operation called PEMDAS;
P = Parentheses
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subtraction
Between multiplication and division, we can carryout anyone first since division can be expressed as multiplication. This is also the case of addition and subtraction.
Note also, the negative sign.
+ x + = +
+ x - = -
- x - = +
Now, let us solve the problem;
(-8.5)(-5)(-2);
we simply solve from left to right; to remove the parentheses simply introduce the multiplication sign;
- 8.5 x - 5 x - 2 = 42.5 (-2)
= -85
Therefore, the expression resolves into -85.
Answer:
-85

What is the slope of the line that passes through the points (10,5)and (15,20)
Answer:
The answer is 3Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(10,5)and (15,20)
The slope is
[tex]m = \frac{20 - 5}{15 - 10} = \frac{15}{5} = 3 \\ [/tex]

Step-by-step explanation:
1. 9 · 9 = 81
2. follow PEMDAS order of operations
5 · 2 = 10
[tex]10^{3}[/tex] = 1000
1000 ÷ 10 = 100
100 + 410 = 510
3. 2 · 2 · 2 · 2 · 2 = 32 · 3 = 96

5. the least common factor is: 24
rewriting as equivalent fractions with the LCD:
2/3 = 16/24 5/8 = 15/24
comparing the numerators of the equivalent fractions we have:
2/3 5/8
16/24 > 15/24
therefore comparison shows:
2/3 > 5/8

George Johnson recently inherited a large sum of money;he wants to use a portion of this money to set up a trust fund for his two children. The trust fund has two investment options: (1) a bond fund and (2) a stock fund. The projected returns over the life of the investments are 6 percent for the bond fund and 10 percent for the stock fund.Whatever portion of the inheritance he finally decides to commit to the trust fund, he wants to invest atleast 30 percent of that amount in the bond fund. In addition he wants to select a mix that will enable him to obtain a total return of atleast 7.5 percent.A) Formulate a linear programming model that can be used to determaine the percentage that should be allocated to each of the possible i nvestment alternativesB) Solve the problem using the graphical solution procedure.
The solution to the given question is "Optimal B = 0.3 and S = 0.7 where 0.088 was its optimal value", and further calculation can be defined as follows:
linear programmingIt is a mathematical formula with something like a system of linear as well as a set of linear programming in which there is a linear optimization problem to the Nonnegative parameters. In this, Let B compensate also for percentages of money held throughout the bond portfolio and S for both the percentage of money held throughout the bond fund.In a fund for stocks.
[tex]Max \ \ 0.06 \ b+0.1 \ S \ \ \ \\\\B \geq 0.3 \ \ \ \ \ \ \ \ \ \ \ \ \text{Bond fund minimum} \\\\0.06 \ B+ 0.1 \ S \geq 0.075 \ \ \ \ \ \ \text{Minimum return} \\\\B+S=1 \ \ \ \ \ \ \ \text{All funds invested}\\\\B,S\geq 0 \\[/tex]
For a maximization problem, just use 5 phases of the visual solution process. Start by measuring the rows which fit the disparities.[tex]B = 0.3 \\ \\0.06 \ B+0.1 \ S = 0.75\\\\ B+s =1[/tex]
It is the very first main principle to use a sign[tex]\geq[/tex], greater than or equal to, that answer is just all points because the third limitation uses an exclamation point, both places on the graph are the answer. Its colored area contains each resolution stage that concurrently fulfills all limitations its Viable Area was named as its location of the approaches to any inequalities. That ideal option exists in which there is limited restriction mostly on bond portfolio and all funds. Making investment constraints converge. Replacement B= 0.3 throughout the restriction invested throughout all resources and settle to S.[tex]B+s=1=10 \\\\0.3+s = 1 \\\\The \ \ s= 0.7 \\[/tex]
Optimal B = 0.3 and S = 0.7 where 0.088 was its optimal value.

Write the equation of the line in slope-intercept form that passes through the points (2, -2) and (-3, -17)
Answer: y = 3x - 8
Step-by-step explanation: If you’re given two points that lie on a line, and you’re asked to write the equation of the line, your first task will be to find the slope of that line using the slope formula.
The slope formula is m = y₂ - y₁ / x₂ - x₁
Substituting our points in, we have -17 - -2 / -3 - 2 which is -15/-5 or 3.
So the slope of our line is 3 which can be used with either one of our
two points to write the equation of the line in point-slope form.
So let's go with the point (2, -2).
Point-slope form is written y - y₁ = m(x - x₁).
Since we're using the point (2, -2), y - y₁ would be y - -2 or y + 2.
Now, m would be 3 and x - x₁ would be x - 2.
So we have y + 2 = 3(x - 2).
To put this equation into slope-intercept form, we would first distribute
the 3 through the parentheses which gives us y + 2 = 3x - 6.
Move the number to the right side of the equation by
subtracting 2 from both sides and we have y = 3x - 8.
So the equation of the line would be y = 3x - 8.
PLEASE HELP!! Find x for all.

What is the measure of angle 1?
2 parallel lines are crossed by a transversal to form 8 angles. Clockwise from top left, the angles are blank, 92 degrees, blank, blank; blank, 2, 1, blank.
A.86°
B.88°
C.90°
92°
Answer:
92°
Step-by-step explanation:
because 1 is parallel to the 92°
Answer:
88 degrees
Step-by-step explanation:
Angle 2 will be equal to 92 degrees since they are corresponding angles
Since angle 1 and angle 2 form a linear pair,
the sum of angle 1 and 2 will be 180 degrees, and since we know the measure of angle 2, we can find the measure of angle 1
angle 1 + angle 2 = 180
angle 1 = 180 - 92
angle 1 = 88 degrees
