Two angles are vertical angles. One angle measure is 95°. What is the measure of the
other angle?
A
85°
B
95°
C
90°
D
45°
By using the definition of vertical angles, we will see that the correct option is B, the measure of the other angle is 95°.
What is the measure of the other angle?We define by vertical angles as angles that share a vertex and are in opposite sides of the two intersecting lines that form that vertex.
Vertical angles always have the same measure, in this particular case, we know that one of the vertical angles has a measure of 95 degrees, then the other vertical angle (whose measure we want to find) will also be 95 degrees, just by definition of vertical angles.
In that way, we conclude that the correct option is B: 95°

a) Let x be the number of games played and let y be the total price.
What in mathematics is a linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
(b)
Pin Lanes: y = 10 + 3x
Strike Lanes: y = 4 + 6x
(c) To find the number of games at which the total price is the same at both places, we can set the two equations equal to each other and solve for x:
10 + 3x = 4 + 6x
6x = 6
x = 1
So the total price would be the same if you played 1 game at both Pin Lanes and Strike Lanes.
(d) Since you want to play 4 games, you can substitute x = 4 into the equation for each place:
Pin Lanes: y = 10 + 3(4) = 22
Strike Lanes: y = 4 + 6(4) = 28
Since 4 games at Pin Lanes costs $22 and 4 games at Strike Lanes costs $28, it would be cheaper to play at Pin Lanes.

B. How much interest did latoya pay on the loan
The total amount that Latoya ended up paying for the machinery, was $ 13, 080 .96
The amount of interest that Latoya paid was $ 980.96

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices. Its opposite sides are parallel to each other. We can also think of a square as a rectangle with equal length and breadth.
What is a square?The wood left over after making the frame and the sandbox is 10 inches.A square is a two-dimensional figure that has four sides and all four sides are equal.Definition. Square is a regular quadrilateral, which has all the four sides of equal length and all four angles are also equal. The angles of the square are at right-angle or equal to 90-degrees. Also, the diagonals of the square are equal and bisect each other at 90 degrees.A square is a four-sided figure whose sides are all the same length and whose angles are all right angles measuring 90 degrees.Square is slang for a person who is conventional and old-fashioned, similar to a Fuddy-duddy.

Elijah is going to send some flowers to his wife. Kingwood Florist charges $1 per rose, plus
$20 for the vase. Anita's Flowers, in contrast, charges $3 per rose and $10 for the vase. If
Elijah orders the bouquet with a certain number of roses, the cost will be the same with
either flower shop. How many roses would there be?
Answer:
There will be 5 roses.
Step-by-step explanation:
Let r = the number of roses.
Total cost =
numberof Roses × price per rose AND cost of vase
Total at Kingwood's
= 1r + 20
Total at Anita's
= 3r + 10
We are looking for r (the number of roses) when the totals at either place are the same.
Set them equal to each other.
1r + 20 = 3r + 10
Subtract 1r.
20 = 2r + 10
Subtract 10.
10 = 2r
Divide by 2.
10/2 = r
5 = r
When Elijah buys 5 roses, the cost is the same at either florist.
Check:
at Kingwood's
= 1r + 20
= 1(5) + 20
=25
At Anita's
= 3r + 10
= 3(5) + 10
= 15 + 10
= 25
5 roses costs $25 at either florist.

Answer:
x = 7
Step-by-step explanation:
You want to know the value of x when the base of a triangle measures 5x+35, and its midsegment measures 35.
MidsegmentThe base of the triangle is twice the length of the midsegment, so you have ...
5x +35 = 2(35)
5x = 35 . . . . . . . . . . subtract 35
x = 7 . . . . . . . . . . divide by 5

Additional comment
The midsegment joins the midpoints of the sides of the triangle.
In more formal terms, the smaller triangle is similar to the larger one with a scale factor of 1/2. That means the parallel segments are related by that scale factor of 1/2: (1/2)(5x +35) = 35.
