Consider the pairs of ratios given in the first column and determine whether or not the ratios form a proportion.
Answers
Answer:
Options 1 and 2 are proportional, the last one isn't.
Step-by-step explanation:
I found option 1 by dividing 8 / 1, then multiplying it by 2 to see if I get 16. I got 16 so it's proportional.
I found the 2nd option by dividing 9 / 4, and then multiplying it by 8 to see if I get 18. I got 18 so it's proportional.
I found option 3 by dividing 16 / 6, and then multiplying it by 4 to see if I get 10. I didn't 10, so it isn't proportional.

Answer:
1920 cm³
Step-by-step explanation:
The volume of a cuboid is the product of its dimensions:
V = LWH
__
These two cuboids have the same width and depth, so can be stacked on top of each other to give a cuboid with the dimensions ...
(14 +10) = 24 cm high
8 cm deep
10 cm wide
Then the volume is ...
V = LWH = (8 cm)(10 cm)(24 cm) = 1920 cm³
The total volume is 1920 cubic centimeters.

Eric is designing a logo for a company. The logo consists of two identical parallelograms joined at their longest sides. One of the parallelograms has a base of 2.5 centimeters and a height of 1.25 centimeters. What is the area of the logo
Answers
Answer:
6.26 cm
Step-by-step explanation:
To find the area of a parallelogram, the formula is just
B * H
so the equation would be
2.5 * 1.25
which would equal
3.13
Since in the question, the logo consists of two identical parallelograms, you would multiply 3.13 by 2 so the equation would be
3.13 * 2
which would equal
6.26

I need to figure out what the value of x is
Answers
Answer:
52
Step-by-step explanation:
The square means that the angle is a right angle, measuring 90 degrees.
90 = 50 + (x - 12)
Subtract 50 from both sides.
40 = x - 12
Add 12 to both sides.
52 = x
it’s a right angle so the entire thing is 90. you already know the 50 so put it aside for now. take the whole 90 and add 12 bc you gotta do the opposite of what it says (-12) and then you get 102. then subtract the 50 and you get 52.

How find a missing length in a triangle system by similarity propertiesIn the figure given below we have a system of three distinct right triangles connected by three colinear segments. Given that the three triangles are similar, we can make of geometry properties for similarity to determine the length of the missing line segment.
In this question we must find a missing length by similarity properties, which is represented mathematically by proportions. From the figure we have the following relationship:
5/y = (5 - x)/(5 - y) = x/1 (1)
From (1) we have the following two formulas:
x = 5/y (2)
x = (5 - x)/(5-y) (3)
(2) in (3):
y = 3

Two angles are complementary. One angle is equal to x + 6 degrees. The other is 3x +9 degrees. What is the measure of x?
Answers
Answer:153
Step-by-step explanation:3x9=27 so then you do 180-27=153 then 153 is your answer i'm sorry if this is incorrect
Hey there!
=> x + 6 + 3x +9 = 90°
=> 4x + 9 + 6 = 90°
=> 4x + 15 = 90°
=> 4x = 90° - 15
=> 4x = 75
=> [tex] \frac{4x}{4} = \frac{75}{4} [/tex]
=> [tex]x = \frac{75}{4} [/tex]
=> x = 18.75
Then ,
=> 18.75 + 6, 3(18.75) + 9
=> 24.75, 65.25
Therefore, the two angles are 24.75 and 65.25
Joey dirves his car 80 miles per hour on the highway. Write an equation that ralates his distance traveled (d) to the time elapsed (t)
Use your equation to determine how many hours it will take joey to travel 320 miles
Answers
Answer:
d=80+t
Step-by-step explanation:
An equation that relates his distance travelled (d) to the time elapsed (t) is d = 80t and the time taken to travel 320 miles is 4 hours.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Joey drives his car 80 miles per hour on the highway.
For 1 hours, the distance travelled is 80 miles,
For t hours, the distance travelled will be 80t miles.
So, distance, d = 80t, which is the required equation.
When the distance is 320 miles, the time taken to travel it is,
t = d / 80
t = 320 / 80
t = 4 hours
Hence the time taken to travel 320 miles is 4 hours.
