Complementary Angles
Explanation:
In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.[1] Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves define also an angle, which is the angle of the tangents at the intersection point. For example, the spherical angle formed by two great circles on a sphere equals the dihedral angle between the planes containing the great circles.
An angle formed by two rays emanating from a vertex.

Answers
Answer:
The integers are the whole numbers, both positive and negative. The next integer after 5 is 6, so there is no integer between them. Since 5 and 6 are consecutive numbers, it is not possible to squeeze another integer between them. So, the answer is none.

Gabby has entered a cooking contest with 6 rounds. In order to earn a medal, she needs a final average score higher than 75. After the first five rounds, her average score is 78. What must her score be in the sixth (final) round to earn a medal? Show your work and answer in a complete sentence.
Answers
Answer:
85
Step-by-step explanation:
We will use the formula
xbar = \sum Xi/N
xbar is the average
N is the number of rounds
\sum Xi is sum of rounds
From the formula:
\sumXi = xbar × N.
If Gabby has entered a cooking contest with 6 rounds and in order to earn a medal, she needs a final average score higher than 75, this means that;
N = 6
xbar = 75+x (since her average needs to be more than 75)
Substitute in the formula
\sumXi = 6(75+x) ....... 1
If after the first five rounds, her average score is 78, then:
At N = 5, xbar = 78
Substitute into the formula
\sumXi = 5(78)
\sumXi = 390..... 2
First we need to get x by equating equation 1 and 2:
6(75+x) = 390
450 + 6x = 390
6x = 390-450
6x = -60
x = -10
Taking x as 10
Since she needs 75+x to earn the medal, substitute x = 10 into the expression:
This means that she will need average score of 75+10 i.e 85 to win the medal

Answers
The distance droved by Charlie is about 38 miles
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
The distance between San Antonio and Houston is 190 miles. Nicholas and Rose each drove 2/5 of the total distance.
Distance droved by Nicholas = Distance droved by rose = (2/5) * 190 = 76 miles
Distance droved by Charlie = 190 - 76 - 76 = 38 miles
The distance droved by Charlie is about 38 miles

Write the point-slope form of the equation of the line that passes through the point (-1,5) and has a slope of -1. Include
your work in your final answer. Type your answer in the box provided to submit your solution.
Answers
Answer:
y= - x + 4
Step-by-step explanation:
The point-slope form of the equation of a line is:
y= m ( x - h )+ k
Where m is the slope and (h,k) is a point through which the line passes.
The slope of the line is m=-1 and it passes through (-1,5), thus the equation of the line is:
y=(-1) ( x - (-1) ) + 5
Operating:
y= - ( x + 1 ) + 5
y= - x - 1 + 5
Simplifying:
y= - x + 4

(8x + 7)
5yº
(7y -- 34)
= (2x - 4)^
Answers
Answer:
x = 11
y = 17
Step-by-step explanation:
We know that opposite angles (or vertical angles) are equal.
So
8x + 7 = 9x - 4
Subtract 8x from both sides of the equation
8x - 8x + 7 = 9x - 8x - 4
7 = x - 4
Add 4 to both sides of the equation
7 + 4 = x - 4 + 4
11 = x
Looking at the other 2 angles,
5y = 7y - 34
Subtract 7 y from both sides of the equation
5y - 7y = 7y - 7y - 34
-2y = -34
Divide both sides by -2
-2y/-2 = -34/-2
y = 17
Answer:
Step-by-step explanation:
Vertically opposite angles are equal.
8x + 7 = 9x - 4 {Add 4 to both sides}
8x + 7 + 4 = 9x
8x + 11 = 9x {Subtract 8x from both sides}
11 = 9x - 8x
x = 11
7y - 34 = 5y {Add 34 to both sides}
7y = 5y + 34 {Subtract 5y form both sides}
7y - 5y = 34
2y = 34 {Divide both sides by 2
y = 34/2
y =17

you got a bunch of apples. one third is rotten, one fourth is ripe. How much is left?
Answers
Answer:5/12
Step-by-step explanation:
1/3=4/12
1/4=3/12
=7/12
12/12-7/12=5/12
One third of 12 =1/3 *12/1
= 4
Therefore 4 apples are rotten
One fourth of 12 = 1/4 *12/1
= 3
Therefore 3 apples are ripe
Number of apples left =. 12- 3 +4
According to the DMAS rule we have to do Addition first ,so 3+4 = 7
Now we have to subtract 12-7 that will be 5
so therefore number of apples left = 5

A conference will take place in a large hotel meeting room. The organizers of the conference have created a drawing for how to arrange the room.

Answer:
The actual length of the room is 40 feet
Step-by-step explanation:
Given
[tex]Scale = \frac{1}{2}\ inch : 12\ feet[/tex]
Required
Determine the actual measurement of [tex]3\frac{1}{3}\ inches[/tex]
Represent the required actual measurement with x
i.e.
[tex]3\frac{1}{3}\ inches : x[/tex]
And we have:
[tex]\frac{1}{2}\ inch : 12\ feet[/tex]
[tex]3\frac{1}{3}\ inches : x[/tex]
Cross Multiply
[tex]x * \frac{1}{2} = 12 * 3\frac{1}{3}[/tex]
Convert fraction to improper fraction
[tex]x * \frac{1}{2} = 12 *\frac{10}{3}[/tex]
[tex]\frac{x}{2} = \frac{120}{3}[/tex]
[tex]\frac{x}{2} = 40[/tex]
Multiply both sides by 2
[tex]x = 40 * 2[/tex]
[tex]x = 80\ feet[/tex]

Solution:
We know that:
Area of triangular pane = 576 in²Height of triangular pane = 48 inArea of triangle formula = 1/2 x Base x AltitudeSubstituting the height and the area of the pane in the formula
Area of triangle = 1/2 x Base x Altitude = 576 in²1/2 x Base x 48 = 576 in²Simplifying the LHS:
1/2 x Base x 48 = 576 in²Base x 24 = 576 in²Dividing 24 both sides
(Base x 24)/24 = 576/24Base = 576/24 = 24 inThus, the measure of the base is 24 inches.

Mangojuicecosts$8.50perquartandbananajuicecosts$6.20perquart.Tyler wants to make a mixture of mange and banana juice that sells for $5.50 per quart. How many quarts "q" of mango juice should he mix with 4 quarts of banana juice to make mango-banana juice at that price? Which equation below represents the situation?
Answers
Answer:
There is no possible combination that will result in mango-banana juice that costs $5.50 per quart if its two ingredients cost $8.50 and $6.20 per quart.
Step-by-step explanation:
the equation you need to solve is:
let M = quantity of mango juice
$8.50M + (4 x $6.20) = (4 x $5.50) + $5.50M
$8.50M + $24.80 = $22 + $5.50M
$24.80 - $22 = $5.50M - $8.50M
$2.80 = -$3M
M = $2.80 / -$3 = -0.933 ⇒ the quantity of mango juice cannot be negative
