Answer:
Step-by-step explanation:
This is actually a very important question and it is very subtle. Let's just take an ordinary segment.
Suppose we have a segment that is this long
=========o=========
The segment up to the o is nine equal signs long.
The segment after the o is also nine equal signs long.
Here's the crunch. Since they are equal, the ratio is 1 to 1. The segment is divided in half.
Now take the second half of the question.
======o============
The left side of the o is 6 equal signs long.
The right side of the o is 12 equal signs long.
The ratio is 1:2. There are still 18 equal signs but now they are divided as 6/12 which is not the same thing as 9/9
Very interesting question.
Answer:
A ratio of 1:2 means that there are 3 parts in total. One part will be before the desired point, and 2 parts will be after the desired point. This is the same as finding the point that is 1/3 the length. Half the length of the segment would mean there would only be two pieces, each of equal size.

Annie lives 12 miles directly south of her school. The grocery store is 5 miles east of Annie's house. Annie needs to stop by the grocery store before driving down the road that connects the store to her school. How far does Annie drive to get to school?
Answer: 18 miles.
Step-by-step explanation:
We can think on this as a triangle rectangle, where one cathetus is 12miles, and the other cathetus is 5 miles. (so the vertex of the triangle rectangle are Annie's house, the school, and the store)
The path that Annie would do is:
From her house to the store (so she drives 5 miles)
And from the store to the school, so here she drives through the hypotenuse of the triangle rectangle.
Then we need to find the length of this triangle rectangle.
We know that the square of the hypotenuse is equal to the sum of the squares of the cathetus, then:
H^2 = (12mi)^2 + (5mi)^2
H = √( (12mi)^2 + (5mi)^2) = 13mi
Then she first drives 5 miles from her house to the store, and then drives 13 miles from the store to the school, then the total distance that she drives is:
5 miles + 13 miles = 18 miles.
Holly has 46 quart of potato salad. She gives 26 quart to a friend. How much potato salad does she have left? Explain.
Answer:
Holly has 20 quart of potato salad left.
Step-by-step explanation:
Holly has 20 quart of potato salad because she originally has 46 quart of potato but gave her friend 26, subtracting 26 from the original amount of quart of potato she had.

Find the length of the third side. If necessary, write in simplest radical form 8 5
Answer: c = [tex]\sqrt{89}[/tex]
8² + 5² = c²
64 + 25 = c²
[tex]\sqrt{89}[/tex] = [tex]\sqrt{c^{2} }[/tex]
[tex]\sqrt{89}[/tex] = c
The length of the third side is 9.4.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
Applying Pythagorean theorem.
Third side = x
x² = 8² + 5²
8 x 8 = 64 and 5 x 5 = 25
So,
x² = 64 + 25
x² = 89
x = √89
x = 9.4333
Rounding to the nearest tenth
x = 9.4
Thus,
The length of the third side is 9.4.

Of the shapes shown, 1/3 are circles and 1 1/2 are rectangles. What fraction of the shapes are either circles or rectangles?
Answer: 1 5/6
Step-by-step explanation:
From the question given, we are told that out of some shapes shown, 1/3 of the shapes are circles and 1 1/2 are rectangles.
The fraction of the shapes that are either circles or rectangles, will be gotten by adding the shapes that are circle to those that are rectangle. This will be:
= 1/3 + 1 1/2
We should make the fraction have a common denominator.
= 2/6 + 1 3/6
= 1 5/6
The answer is 1 5/6.

A 30-foot long escalator forms a 41° angle at the second floor. Which is the closest height of th
141
30 feet
A 20 feet
B. 22.5 feet
C. 24.5 feet
D. 26 feet
Answer:
[tex]\huge\boxed{\text{B) } 22.5 \ \text{feet}}[/tex]
Step-by-step explanation:
We can use basic trigonometric functions to find the closest height of the escalator.
Let's set up a picture from what we already know. The length of the escalator is 30 feet, and it forms a 41 degree angle with the top. Since it will form a 90 degree angle with the ground, we can find the angle between the ground and the beginning of the escalator.
Since all triangles have an angle sum of 180:
[tex]90+41+x=180[/tex] [tex]131+x=180[/tex] [tex]x = 180-131[/tex] [tex]x=49[/tex]Now we know that the triangle looks something like this.
/ | 41°
/ |
/ |
/ |
30 / |
/ |
/ |
/ |
/__________| 90°
49°
We need to find the length of the side between the 41 and 90° angle.
To find which trigonometric operation to use on this triangle, we can use the acronym SOH CAH TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
We can use the sine of the 49 degree angle (opposite / hypotenuse) to find our missing side (since we know the hypotenuse).
Let's set up an equation and solve with our calculator.
[tex]\text{sin}(49) = \frac{\text{opposite}}{\text{hypotenuse}}[/tex] [tex]\text{sin}(49) = \frac{x}{\text{30}}[/tex] [tex]30 \cdot \text{sin}(49) = x[/tex]We can calculate the sine of 49 with our calculator. We'd end up multiply 30 and that value and get 22.6.
Since the closest value to 22.6 on the answer choices is 22.5, the correct answer would be B) 22.5 feet.
Hope this helped!

Subtract 5 from each side
12 + 11/6x - 11/6x -5 ≤ 5+3x-11/6x-5
7 ≤ 3x-11/6x
