Which equation can be used to find the missing angle?
a. X + 90 = 180
b. X + 40 = 90
c. 180 - 40 = x
Answers
Answer:
A, all three angles of a triangle equal 180
Answer:
b. x + 40 = 90
Step-by-step explanation:
This is a right triangle, so we already know one of the angles is 90 degrees. The other angles combine to make the other 90 degrees. So, we have to figure out what the other angle is, as the second one is 40 degrees. To figure that out, use the equation x + 40 = 90. (This is extra, but x is 50, right?)

y = 180- x
y= 180 - 35 = 145

z = 180 - (145 +10)

The minimum distance from Earth to Moon is 226,332 miles
The maximum distance from Earth to Moon is 251,401 miles
What is an Ellipse?
An ellipse is created by a plane intersecting a cone at the angle of its base
All ellipses have two foci, a center, and a major and minor axis
The sum of the distances from any point on the ellipse to the two foci gives a constant value
The value of eccentricity for all ellipses is less than one
The standard for of equation of ellipse is
( x²/a² ) + ( y²/b² ) = 1
where a > b
The length of the major axis = 2a
The length of the minor axis = 2b
The coordinates of foci = ( ±c , 0 )
where c² = a² - b²
Given data ,
The orbit of the Moon around the Earth is an ellipse with Earth at one focus
The length of the major axis 2a = 477,736 miles
The length of the minor axis 2b = 477,078 miles
Now , the value of a = 238,868 miles
The value of b = 238,539
Now , the maximum distance from earth to moon is = a + c
The minimum distance from earth to moon is = a - c
The value of the foci is given by c² = a² - b²
Substituting the values in the equation , we get
c² = ( 238,868 )² - ( 238,539 )²
c² = 157066903
Taking square roots on both sides , we get
c = 12532.63 miles
Now , maximum distance from earth to moon is = a + c
Maximum distance = 238,868 + 12535.63
= 251,400.63 miles
≈ 251,401 miles
Now , The minimum distance from earth to moon is = a - c
Minimum distance = 238,868 - 12535.63
= 226,332.37 miles
≈ 226,332 miles
Hence ,
The minimum distance from Earth to Moon is 226,332 miles
The maximum distance from Earth to Moon is 251,401 miles

What is the value of s?
Answers
Step-by-step explanation:
Sum of angles in a triangle = 180°.
=> s° + (s/7 + 3)° + (s/7 - 3)° = 180°
=> 9/7 * s° = 180°
=> s° = 180° * (7/9) = 140°
Hence the value of s is 140.

At one farmer’s market, bananas cost $0.80 per pound. At another farmer’s market, bananas are sold in 5-pound bags for $4.50 per bag. Which explains how to find the better buy?
Divide 4.50 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0.80 per pound.
Divide 0.80 by 5 to find the unit rate for the 5-pound bag, and compare that number to $0.80 per pound.
Multiply 4.50 by 5 to find the cost for 5 pounds, and compare to $4.50 per bag.
Multiply 4.50 by 0.80 to find the cost for 5 pounds, and compare to $4.50 per bag.

A pulley rotates through 107° in one minute. How many rotations does the pulley make in an hour!
The pulley makes rotations per hour.
(Simplify your answer. Round to the nearest whole number.)
Answers
Answer:
18 rotations.
Step-by-step explanation:
As there are 360 degrees in a circle, by proportion, the time for 1 rotation
= (360/107) * 1
= 3.364 minutes.
So the number of rotations in 1 hour (60 minutes)
= 60 / 3.364
= 17.83
Number of rotations does the pulley make in an hour is 18.
Here,
A pulley rotates through 107° in one minute.
What is rotations?
The action or process of rotating on or as if on an axis or center.
Now,
As there are 360° in a circle, by proportion;
Time for one rotation = (360/107) x 1
= 3.364 minutes
Hence, number of rotations in 1 hour
= 60 / 3.364
= 17.83
So, Number of rotations does the pulley make in an hour is 18.

Triangle ABC has vertices A(-4, 1), B (-1, 3) and C (-1, 1). what would the vertices be if you graphed it’s reflection over the y axis
Answers
If this coordinates are reflected over the y-axis the resulting coordinate will be at A'(4, 1), B'(1, 3) and C'(1, 1)
Generally, if a coordinate (x, y) is reflected over the y-axis, the coordinate of the pre-image is (-x, y).
Note that the x-coordinate was negated while the y-coordinate remain the same.

C
Step-by-step explanation:
a translation over the x-axis keeps the same x value but flips the y value (makes it the opposite.)
so here, C starts at point (1,-2). when reflected over the x-axis this becomes (1,2)
a translation to the left subtracts from the x value
the coordinate changes from (1,2) to (-2,2) because 3 is subtracted from 1
