First step to simplifying ratios is to find the ratio. The ratio would be 14:16. The next step is to find the least common factor and simplify by dividing. The least common factor is 2, so divide both numbers by 2.
[tex]\frac{14 / 2}{16 / 2} = \frac{7}{8}~or~7:8[/tex]
With that info, your answer is 7:8

We learned how to simplify ratios.Janine has 10 pieces of ribbon. She recorded the length of each piece in the line plot below. What is the total length of the four longest pieces of ribbon?
Answer:
51.25
Step-by-step explanation:
The four longest pieces are the four X’s on the farthest right.
These X’s have values of 12.75, 12.75, 12.75, and 13.
12.75 + 12.75 + 12.75 + 13
25.5 + 12.75 + 13
38.25 + 13
51.25
Therefore, my answer is correct.
Answer:
51 1/4 centimeters
Step-by-step explanation:
According to the line plot, the 4 longest pieces of ribbon are :
13, 12 3/4, 12 3/4, and 12 3/4Total length = Sum of the 4 pieces

Question 1: x=12.5
6x+4x+2x+30=180
(One full line forming a semi circle would equal to 180 degrees all the angles given would therefore equal up to that value)
Add like terms to simplify;
12x+30=180
Use inverse operations to isolate the variable!
180-30=150
150/12=12.5
Check ur work!
6(12.5)+4(12.5)+2(12.5)+30=180
75+50+25+30=180
180=180
Question 2: Angle EAF = 25 degrees
Since x equals 12.5
and the equation given to represent the angle is 2x
2(12.5)=25
Question 3: Angle DAE= 50 degrees
x=12.5
Angle DAE=4x
4(12.5) = 50
Question 4: Angle CAD= 75 degrees
x= 12.5
Angle CAD= 6x

What is the area of the trapezoid?
A trapezoid resting on a base. The top side is labeled 14 in. The bottom side is labeled 30 in. The left side is labeled 15 in. The right side is labeled 20 in. Where the left side and the bottom side meet there is a right angle box.
Answer:
29.5 inches squared
Step-by-step explanation:
The formula for the area of a trapezoid is [tex]\frac{base1 + base2 * height}{2}[/tex],
so base1 = 14 inches and base2 = 30 inches
since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches
then, 14+30+15=59 and 59/2=29.5
therefore, your answer would be 29.5 inches squared

Answer the following about estimating 321/6.
Answer:
A) 300/6. B) Underestimate.
Step-by-step explanation:
321/6 is 53.5
300/6 is 50
and 360/6 is 60.
50 is closer to 53.5 than 60 is so the closest aproximation would be 300/6

The probability of rolling 2 even numbers is,
⇒ 1 / 4
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
An experiment involves rolling two dice.
Now, Total possibilities are = 36
And, Number of possibilities to getting even numbers = 9
Hence, The probability of rolling 2 even numbers is,
⇒ 9 / 36
⇒ 1 / 4
Thus, The probability of rolling 2 even numbers is,

Answer:
8; 3 : 8
Step-by-step explanation:
to find out how many shapes there are for every 3 circles you must first reduce the ratio down to 3 : blank
divide both sides by 4
3 : 8
that means there are 8 shapes for every 3 circles
the simplified ratio is 3 : 8

65.8
WILL GIVE BRAINLIEST FOR RIGHT ANSWER! :)
Answer:65.8
Step-by-step explanation:
Now we have: 70 percent of 94 = 65.8
Question: What is 70 percent of 94?
We need to determine 70% of 94 now and the procedure explaining it as such
Step 1: In the given case Output Value is 94.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 94 = 100%.
Step 4: In the Same way, x = 70%.
Step 5: On dividing the pair of simple equations we got the equation as under
94 = 100% (1).
x = 70% (2).
(94%)/(x%) = 100/70
Step 6: Reciprocal of both the sides results in the following equation
x%/94% = 70/100
Step 7: Simplifying the above obtained equation further will tell what is 70% of 94
x = 65.8%
Therefore, 70% of 94 is 65.8

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
The two angles are said to be supplementary angles if their sum is 180 degrees.
By the above property of angle, the equation is written as,
x + 100° + 3x = 180°
Simplify the equation, then we have
x + 100° + 3x = 180°
4x = 80°
x = 80° / 4
x = 20°
The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

Jackson has a cube. Each edge of the cube is 5 centimeters long.
After the paint dries, Jackson cuts the cube in half. He makes the cut along the diagonal of one pair of
parallel faces. Rounded to the nearest thousandth, the diagonal has a length of 7.071 centimeters. Once
the cut is made, Jackson has two identical triangular prisms.
What is the combined area, in square centimeters, of the surfaces of the two prisms that were not painted?
Answer:
35.355 cm
Step-by-step explanation:
if u imagine the 3D cut triangle but at a different angle, u would imagine the legnth of the parallelogram being 7.071 which is the hypotenuse of the triangle... along with the hypotenuse given, they also gave the side lenght of the parallelogram which is 5cm... 5 x 7.071 = 35.355 cm

last week you walked your dog 12.405 miles. this week you walked your dog 15 miles. how many fewer miles did you walk last week than this week?
The dog walked 3 miles less in last week than this week.
What is approximation?An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding.
Given that, last week you walked your dog 12.405 miles. this week, you walked your dog 15 miles.
The dog walked in last week approx = 12 miles
The dog walked this week = 15 miles
The fewer miles did he walked = 15-12 = 3
Hence, the dog walked 3 miles less.
