Tyler is making a wooden post that is 3.5 feet in length he polices marks one and 1/3 in A part on the post after making 20 mark
ZanzabumX [31]

Answer:

Tyler is right

Step-by-step explanation:

Given that:

Lenght of wooden plank used = 3.5 feets

Placement of tick marks = 1 1/3 inches apart

Number of tick marks placed = 20

Recall:

1 foot = 12 inches

Hence, length of wooden post in inches :

3.5 * 12 = 42 inches on length

Total length covered by the ticks placed :

1 1/3 inches * Number of ticks placed

1. 333 * 20 = 26.6667 inches

Unmarked length = length of post - length covered by tickmark

Unmarked length = (42 - 26.6666) inches

Unmarked length = 15.3333 inches.

Hence,

Within 15 - 16 inches are yet to be marked.

John wrote that 5+5=10.
Anvisha [2.4K]

By the additive property of equality, the equations John wrote are equivalent.

<h3>Additive property of equality: Determining equivalent equations</h3>

From the question, we are to determine if the equations John wrote are equivalent.

From the given information,

John wrote that

5 + 5 = 10

Then,

He added n to both sides of the equation to get

5 + 5 + n = 10 + n

From the Additive property of equality, we have that

"<em>If we add or subtract the same number to both sides of an equation, the sides remain equal</em>."

Since, John added the same number, n, to both sides of the equation, the equations John wrote are equivalent.

WILL GIVE BRAINLIST
Sergio [31]

= 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
