Answer:
d. 250π/3
Step-by-step explanation:
A = πr²
A = 3.14(10)² = 314.159
A = 314.159*(5/6) = 261.799
A = 261.799 = 250π/3
Answer:
D
Step-by-step explanation:
You need to set up a ratio between the area of the sector & the area of the circle vs the angle of the sector & 360 degrees.
[tex]\frac{SectorAngle}{360} =\frac{SectorArea}{CircleArea}[/tex]
That above is your formula you need to remember for these equations.
Now let's solve. You've been given the sector angle, which is 300 degrees, and you've been given the radius of the circle, 10 feet.
The area of a circle is the formula: A = πr²
Given that formula and you know the radius. You plug in 10 feet for r and solve for the area.
[tex]A=\pi10^2\\A=314.159[/tex]
Now lets solve for the missing variable (Sector Area).
[tex]\frac{300}{360} = \frac{x}{100\pi }\\100\pi * \frac{300}{360} = \frac{x}{314.159}*100\pi\\100\pi* \frac{300}{360} = x\\\frac{250\pi }{3} = x[/tex]
I kind of messed up since I didn't realize the answer choices were simplified, make sure for the area you don't completely solve the area, keep the pi simple if the answer choices include pi.

Two forces of 25 pounds and 20 pounds act on a body with an angle of 25 degrees between them. What is the magnitude of the resultant force?
a) 13.23 pounds
b) 38.78 pounds
c) 43.95 pounds
d) 53.23 pounds
Answers
Answer:
C) 43.95 pounds
Step-by-step explanation:
got it right on edge :)
The magnitude of resultant force is 43.95 pounds.
The option c is correct.
Resultant force:Two forces are given that,
[tex]F_{1}=25, F_{2}=20,\theta=25 degree[/tex]
The resultant force is calculated by using formula,
[tex]F=\sqrt{F_{1}^{2}+F_{2}^{2}+2F_{1}F_{2}cos \theta } \\\\F=\sqrt{25^{2}+20^{2}+2*25*20*cos25 }\\\\F=\sqrt{625+400+906.307}\\ \\F=\sqrt{1931.307}=43.95[/tex]
Hence, the magnitude of resultant force is 43.95 pounds.

Raja claims that to add two fractions with unlike denominators, first you need to determine the smallest number that is a multiple of both denominators. Then change the denominators in both fractions and keep the numerators the same.
Answers
Answer:
Incorrect
Step-by-step explanation:
This is incorrect. In order to add two fractions that have unlike denominators, it is true that you first need to find a common denominator. When you change a fractions denominator you must also change it's numerator in proportion to the change in the denominator. For example, if you change the denominator in the fraction [tex]\frac{1}{2}[/tex] into a 4 then you are multiplying the denominator by 2, therefore you will also need to multiply the numerator by 2 which would give you a new fraction of [tex]\frac{2}{4}[/tex]

Lamar drinks 8 ounces of water with breakfast, 6 ounces of water with his vitamins, 16 ounces of water with his lunch, 16 ounces of water with his dinner, and 32 ounces of water from a bottle he carries throughout the day. Write and evaluate a numerical expression for the amount of water in ounces that he drinks in a week.
Answers
Given:
Lamar drinks water with,
Breakfast = 8 ounces
Vitamins = 6 ounces
Lunch = 16 ounces
Dinner = 16 ounces
Bottle = 32 ounces
To find:
The a numerical expression for the amount of water in ounces that he drinks in a week.
Solution:
One day consumption of water by Lamar is
[tex]8+6+16+16+32=78[/tex]
We know that,
1 week = 7 days
One day consumption of water = 78 ounces
1 week (7 days) consumption of water = 7× One day consumption of water
= 7×(8+6+16+16+32) ounces
= 7×78 ounces
= 546 ounces
Therefore, the required numerical expression for the amount of water in ounces that he drinks in a week is 7×(8+6+16+16+32) ounces and the value is 546 ounces.

(ABCD) = (A'B'C'D'). If A is (6, −8), A' is (−2, 4), and B is (4, −6), what are the coordinates of B'?
Answers
Answer: (6, 6)
In this problem the point is moved over 2 up and 2 to the right form A to A'
The coordinates of B' are (-4, 6).
What is translation?A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Since (ABCD) = (A'B'C'D'), we know that corresponding points in the two quadrilaterals have equal coordinates.
Therefore, we can use the coordinates of A and A' to find the translation vector that takes A to A'.
We can then apply this same vector to B to find its image B'.
The translation vector that takes A to A' is given by the difference A' - A:
A' - A = (-2, 4) - (6, -8) = (-8, 12)
So, the same translation vector takes B to B', and we have:
B' = B + (-8, 12) = (4, -6) + (-8, 12) = (-4, 6)
Therefore, the coordinates of B' are (-4, 6).

When you find a point on a graph that you think is the intersection, the best way to double check your answer is to:
substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.

substitute in the y value to see if one of the x values of one of the equations matches the one you approximated from the graph.
substitute in the x value to see if both of the x values of both of the equations match the one you approximated from the graph.
Answers
Answer: Substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
Step-by-step explanation:
I guess that we are working with systems of equations like:
y = f(x)
y = g(x)
Where an intersection is a solution that works for both equations, which means that the graphs will intersect each other in that point.
This means that for a given value x = x0, we must have:
f(x0) = g(x0).
Now, when you find a point that you think that is an intersection, you should substitute the x value in both functions, and see if the y-values coincide.
This will be equivalent to look if f(x) = g(x) for that particular value.
then the correct option is:
substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
slope = 5, goes through the point (2, 7)

Answers
Answer:
Step-by-step explanation:
Let us represent
Let the wood bat = w
Let the base ball bats = b
Savelot offers two types of baseballs bats the wood bat sell for 24$ and the metal bats sell for 30 in one day save lots sold 23 base ball bats these recipts for those bats totaled $606 how many of each type of bat was sold
System of Equations
w + b = 23.... Equation 1
b = 23 - w
24w + 30b = 606..... Equation 2
We substitute:30 - w for b
Hence:
24w + 30(23 - w) = 606
24w + 690 - 30w = 606
24w - 30w = 606 - 609
-6w = -84
w = -844/-6
w = 14 wood bats
b = 30 - 14
b = 16 base ball bts
