Answer:

Step-by-step explanation:

The coefficients of this quadratic equation are {3, -5, -7}.  The discriminant (part of the quadratic formula) is b^2 - 4ac, which here is 25 - 4(3)(-7), or 109.

This positive discriminant indicates that there are two real, unequal roots.  

They are:

      5 ± √109

Answer:

the number of short sleeves sold is 42

Step-by-step explanation:

The computation of the number of short sleeves sold is shown below:

Given that

The clothing store sold 98 long sleeve shirts

And, the ratio of short sleeve to long sleeve is 3:7

So, the number of short sleeves sold is

= 98 × 3 ÷ 7

= 42

Hence, the number of short sleeves sold is 42

Answer:

Step-by-step explanation:

1 in^2 = 5 mi * 5 mi = 25 mi^2

2.5 in^2 (25 mi^2/in^2) = 62.5 mi^2

Answer:

A, C, and E.

Step-by-step explanation:

I looked up what half a mile was in meters, yards, and feet, and it told me these were the right answers.

The equivalent to 1/2 mile:

A. 804.5 meters

C. 880 yards

E. 2,640 feet

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

To convert 1/2 mile to other units of distance:

1/2 mile = 0.5 mile

A. 804.5 meters ≈ 0.5 miles

(1 mile ≈ 1609 meters, so 0.5 miles ≈ 804.5 meters)

B. 845 meters ≈ 0.524 miles (1 mile ≈ 1609 meters, so 845 meters ≈ 0.524 miles)

C. 880 yards ≈ 0.5 mile (1 mile = 1760 yards, so 0.5 mile = 880 yards)

D. 3,520 yards ≈ 2 miles (1 mile = 1760 yards, so 2 miles = 3520 yards)

E. 2,640 feet ≈ 0.5 mile (1 mile = 5280 feet, so 0.5 mile = 2640 feet)

F. 10,560 feet ≈ 2 miles (1 mile = 5280 feet, so 2 miles = 10560 feet)

Therefore, the distances that are equivalent to 1/2 mile are A, C, E.

Answer:

A. 288

Step-by-step explanation:

EDG 2021

The number of sedans are 288, the correct answer is A.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

We need to Write the percent as a fraction in simplest form

16.24%

So, we can rewrite it as;

16.24 / 100

16 and 24/100 or 16 6/25

So the percent as a fraction is 16 6/25

We are given that;

The percentage of sedans is 5% and the total number of vehicles is 5769.

Now,

Plugging these values into the formula, we get:

Number of sedans = (5 / 100) x 5769 Number of sedans = 0.05 x 5769 Number of sedans = 288.45

Rounding this result to the nearest whole number, we get:

Number of sedans = 288

Therefore, by the given percentage the answer will be 288.
