Solve the quadratic equation
3x²-5x-7=0
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

Please select the best answer from the choices provided
A

D
Answer:
A. 288
Step-by-step explanation:
EDG 2021
The number of sedans are 288, the correct answer is A.
How to find the percentage from the total value?
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.

The sum of the three interior angles of any triangle equal 180 degrees. One right triangle has one acute angle of 30 degrees.
Find the second acute angle.
Paragraph: Describe how to find the second acute angle.
Answer: right triangle is a triangle with one angle equal 90. That being said, the total of all angles = 180. 1 of them is 90 which makes the sum of the 2 acute angles = 90. One acute angle = 30 => the second one = 90 - 30 = 60 degree

What is multiplication?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.
