If an angle is bisected to form two new 10 degree angles, what was the measure of the original angle?
Answer:
20 degrees
Step-by-step explanation:
Bisected means to cut or divide in half. After knowing this you should realize that the two new parts of the angle should be equal. They are both ten degrees, so to get the measure of the original angle add both of the sides together.
10+10=20
A car travels 60 miles due north then makes a turn due west. It travels 72 miles west. How far is the car from its starting point? Round to the nearest tenth.
Answer:
93.7 miles
Step-by-step explanation:
This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.
We need to find the hypotenuse. We can use Pythagoras rule:
[tex]hyp^2 = opp^2 + adj^2[/tex]
where opp = opposite side to the angle considered
adj = adjacent side to the angle considered
This implies that:
[tex]x^2 = 60^2 + 72^2\\\\x^2 = 8784\\\\x = \sqrt{8784} \\\\x = 93.7 miles[/tex]
The car is 93.7 miles far from its starting point.

The lengths of the sides of a triangle are consecutive odd numbers. What is the length of the longest side if the perimeter is 45?
Answer:
17
Step-by-step explanation:
Let x be the first side
x+2 is the next side ( consecutive odd number)
x+4 is the third side ( consecutive odd number)
P = x + x+2 + x+4
45 = x + x+2 + x+4
Combine like terms
45 = 3x+6
Subtract 6 from each side
45-6 = 3x+6-6
39 = 3x
Divide by 3
39/3 = 3x/3
13 =x
The longest side is
x+4
13+4 = 17
The longest side is 17
The longest side is 16.
Let the consecutive sides be y, y+1, and y+2.
The perimeter of a triangle is gotten by adding all its sides. Therefore, the perimeter will be:
y + y+1 + y+2 = 45
Collect like terms
3y = 45 - 3
3y = 42
Divide both side by 3
3y/3 = 42/3
y = 14
Therefore, the longest side will be:
y + 2 = 14 + 2 = 16
The longest side is 16.

which choice is equivalent to the quotient below?
Answer:
A.) 3
Step-by-step explanation:
Let's start with the numerator:
√36/√4
√36 = ?
We know that 36 is a perfect square, or the product of one number multiplied by itself.
6 x 6 = 36
So, √36 = 6
Let's look at the denominator:
√36/√4
√4 = ?
We know that 4 is also a perfect square.
2 x 2 = 4
So, √4 = 2
Now we have the numerator: 6
And the denominator: 2
Fraction: 6/2
If we simplify this fraction, we are left with 3 because 6 divided by 2 is 3.
Therefore, the first answer is correct.
Answer:

Step-by-step explanation:
fill in the blank. given O below you can conclude that PY is congruent to ______ .
Chord PY is congruent to Chord NL of a circle with center 0. Option A is correct.
Given,
A circle with center o is shown with two chords equidistant from the center which is 3 units.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²,
where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.
Since the property of the circle describes that chords that are equidistant from the center of the circle are equal in length,
In the given question both the given chords are equidistant from the center of the circle i.e 3 units, so the Chord PY is congruent to Chord Nl.
Thus, Chord PY is congruent to Chord NL of the circle with center o. Option A is correct.

Use the elimination method to solve the system of equations. Choose the
correct ordered pair.
7x+4y= 39
2x + 4y = 14
A. (3,2)
B. (5,1)
C. (5,4)
D. (3,4)
Answer:
The answer is B.
Step-by-step explanation:
When Elimination method is applied, you have to eliminate one of the variables from both equations. Firstly, both equations contain 4y so you can subtract it :
[tex]7x + 4y = 39 - - - (1)[/tex]
[tex]2x + 4y = 14 - - - (2)[/tex]
[tex](1) - (2)[/tex]
[tex]7x + 4y - 2x - 4y = 39 - 14[/tex]
[tex]5x = 25[/tex]
[tex]x = 25 \div 5[/tex]
[tex]x = 5[/tex]
Next, you have to substitute x = 5 to any equations. I will choose to put in (2) :
[tex]substitute \: x = 5 \: into \: (2)[/tex]
[tex]2(5) + 4y = 14[/tex]
[tex]10 + 4y = 14[/tex]
[tex]4y = 14 - 10[/tex]
[tex]4y = 4[/tex]
[tex]y = 4 \div 4[/tex]
[tex]y = 1[/tex]
Therefore, put your answer in coordinate form :
[tex]x = 5 \\ y = 1[/tex]

A model lighthouse uses a scale of 1/4 inch = 5 feet. The height of the model lighthouse is
6 3/8 inches
What is the height of the actual lighthouse?
Answer:
127 1/2 feet
Step-by-step explanation:
A model lighthouse uses a scale of 1/4 inch = 5 feet.
This means that 1/4 inch on the model represents 5 feet in actual life.
The height of the model lighthouse is 6 3/8 inches i.e. 51/8 inches.
The height of the actual lighthouse is:
1/4 inch = 5 feet
51/8 inches = x
Cross-multiply:
51/8 * 5 = 1/4 * x
=> x = 51/8 * 4 * 5
x = 127 1/2 feet
The height of the actual lighthouse is 127 1/2 feet.

For every 12 slices of pizza sold at Ping's Pizza Shop,
3 slices are pepperoni, 4 are sausage, and the rest are
cheese. What is the ratio of pepperoni to cheese?
Answer:
3:5 Is the ratio because there are five pieces of cheese.
Step-by-step explanation:
If there are 12 pieces, then you can add 4 and 3 together and get 7 and then you can take 7 from 12 and get 5 which is how many cheese pieces there are. Now you know that there are 3 slices of pepperoni and 5 pieces of cheese. Therefore the ratio is 3:5.

Sarah can eat 45 blueberries in 2 minutes. If she eats blueberries for 45 minutes straight, how many did she eat?
Answer:
1012
Step-by-step explanation:
She eats 1012 because:
If she eats 45 in 2 minutes then she eats 22.5 in 1 minute.
This is because 45 ÷ 2 = 22.5
Sarah eats blueberries for 45 minutes so we multiply 22.5 by 45
22.5 × 45 = 1012.5
She ate 1012 full berries.
