2 answers:

Judging by the given information i would say A. it seems like there should be a diagram to accompony. But, c is wrong because its not rounded to .25
D. is just an outliar
it's between A and B. a diagram would answer that. it depends which the point is closer to. I'm saying A. because it sounds like the exercise wants you to use the decimal.

Answer:

Option (a) is correct.

14.25 inches is the most appropriate way to report length using this ruler

Step-by-step explanation:

Given : A ruler measures length to the nearest 0.25 inches.

We have to find the most appropriate way to report length using this ruler.

Since, the ruler measures length to the nearest 0.25 inches thus, it appropriately measure only that length which has 0.25 in its decimals.

Thus, out of given options (a) 14.25 inches is only option that has 0.25 in its decimals.

Thus, option (a) is correct.

14.25 inches is the most appropriate way to report length using this ruler

What is the difference in Fahrenheit degrees between a temperature of 0C and a temperature of 15C?

slamgirl [31]

Answer:

$27^{\circ}F$

Step-by-step explanation:

Use formula

$F=1.8C+32$

to convert Celsius to Fahrenheit.

When $C_1=0^{\circ}C,$ then

$F_1=1.8\cdot 0+32\\ \\F_1=32^{\circ}F$

When $C_2=15^{\circ}C,$ then

$F_2=1.8\cdot 15+32\\ \\F_2=27+32=59^{\circ}F$

Difference:

$F_2-F_1=59^{\circ}F-32^{\circ}F=27^{\circ}F$

A certain radioactive isotope has leaked into a small stream. Three hundred days after the leak, 3% of the original amount of t

sesenic [268]

If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days

Brian tied a 136-foot rope around the perimeter of his rectangular house. He knows that the length of the house is 10 feet less

STALIN [3.7K]

Answer:

length 42 cm and width 26 cm

Step-by-step explanation:

Given

Since Brian tied 136 foot rope around the perimeter , hence perimeter of house is 136 foot.

Given that shape of house is rectangular.

formula to calculate perimeter of rectangle can be used which is 2*(L+B)

where L is length of rectangle and B width of rectangle

Let the L and B be length of rectangular side of house

According to question

length of house is 10 feet less than twice the width of house

mathematically it can be represented as

L = 2*B - 10 --->eq. 1

Perimeter of house = 136 feet

using formula of Perimeter of rectangle

136 = 2*(L+B)

substituting the value of length in terms of width from eq. 1 in formula of perimeter

=> 136/2 = 2*B - 10 + B (2*B+ B = 3B)

=> 68 = 3*B - 10

=> 78 = 3*B

B = 78/3 = 26

Therefore B which is width = 26 CM

length = 2*B - 10= 26*2 - 10 = 52-10=42

length of house = 42 cm

Hence dimension of Brian's house is length 42 cm and width 26 cm
