Correct answer is Option A: 18/48 = 21/56

You’ll have to divide the numerator by the denominator of each fraction to see whether they have the same quotient:

18/48 = 0.375
21/56 = 0.375


The other options are not proportional.

B) 20/28 = 15/18:

20/28 = 0.714
15/18 = 0.833

Thus, 20/28 ≠ 15/18

C). 3/5 = 13/10
3/5 = 0.6
13/10 = 1.3

Hence, 3/5 ≠ 13/10

D) 7/10 = 10/7
7/10 = 0.7
10/7 = 1.43

Thus, 7/10 ≠ 10/7

These solutions prove that the correct answer is A) 18/48 = 21/56

It is possible to measure the length of a line
zubka84 [21]

Answer:

In summary, a line segment is a part of a line with two distinct end points. You can find the length of a line segment by solving an equation when the length of two lines segments is known. The length of line segments on the Cartesian plane can be found by counting the units that the line segment covers.

Step-by-step explanation:

Measure line segments. While the length or the measure is simply written AB. The length could either be determined in Metric units (e.g. millimeters, centimeters or meters) or Customary units (e.g. inches or foot). Two lines could have the same measure but still not be identical.

The force on an area 16 m by 12 m is 24,000 N. What is the pressure per square meter?
Dmitrij [34]
Recall that 
Pressure = Force ÷ Area

In this context we have,
Pressure = 24,000 ÷ (16 × 12)
               = 24,000 ÷ 192
               = 125 Pa

Answer:

D. x=8.57

Step-by-step explanation:

We can see from our graph that triangle CED is similar to triangle CBA. Side length BA corresponds to ED and Side length AC corresponds to DC.

Since we know that corresponding sides of two similar triangle are in the same proportion. To find value of x we will set proportion of the corresponding sides of our given triangles equal.

\frac{x+15}{15} =\frac{11}{7}          

Upon cross multiplying our given equation we will get,

7(x+15)=11\times 15

Upon distributing 7 we will get,

7x+105=11\times 15

7x+105=165

7x=165-105

7x=60  

x=\frac{60}{7}

x=8.5714285714285714\approx 8.57

Therefore, x equals 8.57 and option D is the correct choice.

A liquid substance was left at the scene of the crime. Krisann uses a beaker that measures to the nearest tenth of a liter and f
AVprozaik [17]
4.85 <= x < 4.95 .  does not intersect x > 5.No it does not need to be sent to the lab. B.
<span>yes, since the beaker meaures to the nearest tenth of a liter , the range of the actual value is plus or minus 0.1 liters , which means there could be up to 5 liters of the substance </span>
