Samuel drove 28 miles in 32 minutes. Beverly drove 42 miles in 48 minutes.
Are the ratios of miles to minutes for Samuel and Beverly proportional?
Drag and drop to correctly complete the statement.
= Ratio of minutes to miles in which Samuel drove = 28 : 32
= Ratio of minutes to miles in which Beverly drove = 42 : 48
To find whether the time they drove and the distance they covered were proportional or not , let us first change them into a fraction and then simplify them .
= 28 : 32 = 28/32
= 28/32
Both the numerator and the denominator is divisible by 4 .
= 28 ÷ 4 / 32 ÷ 4
= 7/8 = 7 : 8
Samuel = 7 : 8
Beverly = 42 : 48 = 42/48
= 42/48
Both the numerator and the denominator is divisible by 6 .
= 42 ÷ 6 / 48 ÷ 6
= 7/8
Therefore, the ratio of miles to minutes drove by Samuel and Beverly is proportional , 7:8 :: 7:8
Answer:
7:8 7:8
Step-by-step explanation:
if you subtract 28 from 42 and subtract 32 from 48 then you get 14-16. then double it and you get 28-32 then add 14-16 to those again and you get 42-48. because they add up and are equal, take 14-16 and simplify it to 7:8.

AM I CORRECT DO I NEED TO ADD AN ANSWER OR TAKE AWAY ONE
You should take off E and add C and D because perpenidcular bisector means not only does it form a right angle to the line, it also bisects it, or cuts it into 2 equal portions. Also, If you look at triangles BED and BEF, they are congruent as both have right angles and equal sides BE, and DE = EF. So, BD = BF.
E is wrong because you don't know if line AC is perpendicular to DA, nor do you know if it's parallel to DF. And you don't know if DA is parallel to BE either. You ONLY know that BE is the perpendicular bisector of DF.

Answer:
-45
Step-by-step explanation:
Sum of two integers = -30

x = -45
so the other number is -45

Answer:
Vertical stretch of 2
Step-by-step explanation:
Since there is no fraction, it wouldn't be a shrink, and there's a negative symbol therefore it would also be a reflection, and it wouldn't translate down because it's not inside parenthesis or the square root, and it would actually translate up three, therefore it's a vertical stretch of two

|x + 7| = 3x - 5
Answer:
x=6
Step-by-step explanation:
x+7=3x-5
add 5 to both sides
x+12=3x
subtract x from both sides
12=2x
divide by 2 on both sides
6=x

The number 51 is decreased to 26. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
Answer:
-49%
Step-by-step explanation:
i know this one by doing a long math formula
Answer:
49.0%
Step-by-step explanation:
take the 2 numbers and find the difference
51 - 26 = 25
take the difference and divide it by the orginal number
25÷51 = 0.49019607843
then times that number by 100
(25÷51) × 100 = 49.0196078431
so the number was decreased by 49.0 %

8x + 4.3= 2(x+6) + 6x - 7.7
Answer:
Step-by-step explanation:
8x=2x+12+6x-7.7-4.3
8x=2x+12+6x-12
8x=8x
x=x
X could be any number
Example : If x=4
4*8+4.3=2(4+6)+6*4-7.7
32+4.3=20+24-7.7
36.3=36.3

Given f(x)=2x+1, find the range value if the domain value is 1.75. *
Answer:
4.5
Step-by-step explanation:
Domain means that value of x and range means the value of f(x) so
[tex]f(x)=2x+1 \\f(1.75)=2(1.75)+1\\f(1.75)=4.5[/tex]
so the range value is 4.5
