Answer:
Step-by-step explanation:
Sum = -5
Product = -14
Factors = 2 , (-7) because 2*(-7) = -14 and 2 + (-7) = -5
x² - 5x - 14 = 0
x² + 2x - 7x - 14 = 0
x(x + 2) -7(x + 2) = 0
(x + 2)(x - 7) =0
x + 2 = 0 ; x -7 =0
x = -2 ; x = 7
a homeowner has just installed a swimming pool with a capacity of 3.5 x 10⁴ gallons.of the pool is initially empty, how many hours will it take to fill it using only a garden hose that delivers 630 gallons of water per hour
Using proportions, it is found that it will take 55.6 hours to fill the poll.
What is a proportion?A proportion is a fraction of total amount, and the measures are related using a rule of three.
In this problem, in one hour, 630 gallons of water are delivered. How many hours are going to take to deliver 3.5 x 10⁴ gallons = 35000 gallons?
The rule of three is:
1 hour - 630 gallons
x hours - 35000 gallons
Applying cross multiplication:
[tex]630x = 35000[/tex]
[tex]x = \frac{35000}{630}[/tex]
[tex]x = 55.5[/tex]
It will take 55.6 hours to fill the poll.

The hours it would take to fill the swimming pool is 55.6 hours.
What does division mean?
Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷.
How many hours would it take to fill the swimming pool?Number of hours = capacity of the swimming pool / capacity of the hose
3.5 x 10^4 / 630
35,000 / 650 = 55.6 hours

Answer:
The answer is B
Step-by-step explanation:
Since parallelograms have a total of 360 degrees, you just have to add the 115 and 64 to get 179. The 124 is completely irrevant in this entire problem. So then 360-179=181. It is B because y is an acute angle, meaning that the value HAS to be under 90 degrees, and only B has y as an acute angle measurement.

west will the ship have traveled by 1:00 p.m.? Draw a picture!
Round to the nearest tenth.
9514 1404 393
Answer:
24.6 Nm north67.7 Nm westStep-by-step explanation:
In x-y coordinates, the direction is 70° CCW from 90° (north), so is 160° from the +x axis. In 4 hours at 18 Nm/h, the ship will travel 4×18 Nm = 72 Nm.
The coordinates in the x-y plane can be found to be ...
72(cos(160°), sin(160°)) ≈ (-67.7, 24.6)
The ship traveled 67.7 nautical miles west and 24.6 nautical miles north from the port.

Jamal needs to purchase a countertop for his kitchen. Jamal measured the countertop as 5 ft. The actual measurement is 4.5 ft. What is Jamal’s percent error?
A) 5%
B) 11%
C) 45%
D) 50%
Answer:
percent error is 11.1% (which agrees with answer B)
Step-by-step explanation:
The discrepancy (difference) between the measurement and the real length was: 5 - 4.5 = 0.5 ft
Then the percent difference is calculated as:
(difference / real value) * 100 = ( 0.5 / 4.5ft ) * 100 = 11.1%

four pieces of pie were eaten from a pie cut into equal parts. The 5 pieces that remained created an angle that measured 200°. What was the angle measure of one piece of pie
Step-by-step explanation:
The 5 pieces that remained created an angle that measured 200 degree means that the 4 pieces made 360-200 degrees 160o.
If all four made 160 then each has to be 160/4 = 40o
200/5 also gives you 40 (the five remaining)
360/9 would also give you 40 9the 5 remaining and the 4 eaten)

Hey!
So what it's asking for is the slope of the line. You can figure this out by finding two solid points on the line, such as (0,-1) and (4,2).
Knowing that these are two solid points, you can use the Rise/Run method to get the answer. The rise is how many units the slope rises (+) or falls (-) when getting to the next point. The run is how many units to the left or right it goes.
By following this, the slope is 3/4
