Answer:
BC = 100°
Step-by-step explanation:
You want the measure of arc BC formed by two chords that intersect at 85° and intercept an opposite arc of 70°.
Angle at crossing chordsThe angle formed by crossing chords is the average of the angles they intercept. Here, that means ...
85° = (? +70°)/2 . . . . the crossing angle is 85°
170° = ? +70° . . . . . . multiply by 2
100° = ? . . . . . . . . . subtract 70°
The intercepted arc BC is 100°.

8) The percent of people that said that Pinocchio was their favorite Disney Movie is of: 28%.
9) The percent of people that said that Pinocchio or Cars was their favorite Disney movie is of: 39%.
10) The two movies that about half the people say were their favorite is of: Pinocchio and Toy Story.
How to obtain the percentages?From the pizza graph, the sum of all the percentages must be of 100%, hence the Pinocchio percentage is obtained as follows:
10 + 11 + 14 + 15 + 22 + P = 100
72 + P = 100
P = 100 - 72
P = 28%.
Then the percentage for Pinocchio or Cars is of:
28 + 11 = 39%.
The percentage for Pinocchio or Toy Story is of:
28 + 22 = 50%.

Write two expressions (with at least two terms each) that when added together have a sum of -4 n + 6.
100 POINTS AND BRAINLIEST
The requried expressions that when added together have a sum of -4 n + 6 are -3n - 2 + 7n + 8 and -5n - 1 + 9n + 7.
What is the equation model?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
We can write two expressions that when added together have a sum of -4n + 6 as follows,
-3n - 2 + 7n + 8
Here, the first expression is -3n - 2, and the second expression is 7n + 8.
When we add these two expressions together, we get:
(-3n) + (7n) + (-2) + 8 = 4n + 6
So the sum of the two expressions is -4n + 6.
Again,
-5n - 1 + 9n + 7
Here, the first expression is -5n - 1, and the second expression is 9n + 7.
When we add these two expressions together, we get:
(-5n) + (9n) + (-1) + 7 = 4n + 6
So the sum of the two expressions is -4n + 6.
Thus, the requried expression that when added together have a sum of -4 n + 6 are -3n - 2 + 7n + 8 and -5n - 1 + 9n + 7.

The top of a coffee table is in a shape of a rectangle.The length of the top of the coffee table is 3.5 feet and the area is 14 square feet.What is the widthof the topof the coffee table?
Answer:
4 feet
Step-by-step explanation:
We can use the formula for the area of a rectangle to find the width of the coffee table:
Area = Length x Width
Substituting the given values, we get:
14 = 3.5 x Width
To solve for the width, we can divide both sides by 3.5:
Width = 14 / 3.5
Simplifying the right-hand side, we get:
Width = 4
Therefore, the width of the top of the coffee table is 4 feet.

Applying the centroid theorem, the length of QK in the triangle is: 10.
What is a Centroid of a Triangle?The centroid of a triangle is the point of intersection of the three medians of the triangle. A median is a line segment that connects a vertex of a triangle to the midpoint of the opposing side. T
What is the Centroid Theorem?The Centroid Theorem states that the centroid of a triangle is located two-thirds of the distance from each vertex to the midpoint of the opposite side.
In other words, if G is the centroid of triangle ABC, then AG = (2/3)AD, BG = (2/3)BE, and CG = (2/3)CF, where D, E, and F are the midpoints of sides BC, AC, and AB, respectively.
Therefore, given that:
Q is the centroid of ΔJKL
PQ = 5
Thus, PQ = 1/3(PK) [according to the centroid theorem]
Substitute:
5 = 1/3(PK)
15 = PK
PK = 15
QK = PK - PQ
QK = 15 - 5

which equation can be used to find the measure of angle fge?
The measure of angle fge is 53.13°.
The equation used to find the measure of angle fge is the Law of Cosines. The Law of Cosines states that for any triangle, the square of the length of any side is equal to the sum of the squares of the other two sides, minus twice the product of those sides and the cosine of the angle opposite the side.
Using the Law of Cosines, we can solve for the measure of angle fge as follows:
[tex]fge = cos-1((a^2 + b^2 - c^2) / 2ab)[/tex]
For example, if the length of side a is 3, the length of side b is 4, and the length of side c is 5, then the measure of angle fge can be calculated as follows:
fge =[tex]cos-1((3^2 + 4^2 - 5^2) / 2(3)(4))[/tex]
fge = [tex]cos-1(1/6)[/tex]
fge = 53.13°

The Jones family will take a drive for one and one-half hours. They need to reach their destination by 1:15 PM. What is the latest time they can leave and still reach their destination on time?
PLEASE I NEED THE ANSWER NOW⁉️⁉️
Answer:
If the Jones family needs to reach their destination by 1:15 PM and their drive will take one and a half hours, we can work backwards to determine the latest time they can leave.
Subtracting 1.5 hours from 1:15 PM, we get:
1:15 PM - 1.5 hours = 11:45 AM
Therefore, the latest time the Jones family can leave and still reach their destination on time is 11:45 AM.

The principal investment was $[tex]1,200.[/tex] Answer: $[tex]1,200.[/tex]
What is the savings account?We know that after 5 years, the amount of money earned on the savings account is $ [tex]1,422[/tex], and the equation that relates the amount A to the principal P and the time t is:
[tex]A = P(1 + 0.037t)[/tex]
We can use this equation to find the value of P:
A = $[tex]1,422[/tex]
t = 5 years
[tex]0.037[/tex] is the interest rate per year
[tex]A = P(1 + 0.037t)[/tex]
$[tex]1,422 = P(1 + 0.037\Ttimes 5)[/tex]
$[tex]1,422 = P(1.185)[/tex]
To solve for P, we divide both sides of the equation by 1.185:
