w2 – 16w – 19 = 0
Answers
Answer:
Factoring w2-16w+19
The first term is, w2 its coefficient is 1 .
The middle term is, -16w its coefficient is -16 .
The last term, "the constant", is +19
Step-1 : Multiply the coefficient of the first term by the constant 1 • 19 = 19
Step-2 : Find two factors of 19 whose sum equals the coefficient of the middle term, which is -16 .
-19 + -1 = -20
-1 + -19 = -20
1 + 19 = 20
19 + 1 = 20
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
w2 - 16w + 19 = 0

Step-by-step explanation:
Multiply 56 by 7/8 to determine the amount of red marbles.
*56 can be put over 1.
Multiply;
[tex] \frac{56}{1} \times \frac{7}{8} = \frac{392}{8} [/tex]

So these apple pies have a ratio of 15 apples to 3 pies. How many apples do you need for 12 pies?
Answers
Answer:
60
Step-by-step explanation:
since 15 apples makes 3 pies you divided 15 by 3 and get 5. 5 apples for one pie so that would be 5 x 12 = 60
Answer:
Since with 15 apples we are able to make 3 pies, this means that in each pie there are 5 apples (15apples divided by 3 pies = 5 apples.)
If there are 12 pies we simply have to multiply 12x5 which equals 60, this means that if we needed to make 12 pies we would need 60 apples.
15apples:3pies = 60apples:12pies
Patty wants a triangular garden in her backyard to grow vegetables. She plans to use three pieces of edging that measure 7 feet, 10 feet and 8 feet. In at least two complete sentences, answer the following questions: a) Will her garden be in the shape of a right triangle? b)Why or why not?
Answers
Answer: Yes.
Step-by-step explanation: With a triangle, the hypotenuse, or the longest side, would be on the bottom. The legs, or the other two sides, pretty much build off of that hypotenuse, which makes it a right triangle.

27) Electric vehicles often have been proposed as an environmentally sound alternative to the gasoline engine for transportation. In response to state initiatives, several car manufacturers now include electric vehicles among their available models. In spite of these state initiatives, the penetration of electric vehicles into the transportation sector of the United States, as well as other countries, remains modest. (a) Identify and describe two environmental benefits to using electric vehicles in place of gasoline-powered engines for transportation. (b) Estimate the potential reduction in petroleum consumption (in gallons of gasoline per year) that could be achieved in the United States by introducing electric vehicles under the following assumptions: 1. The mileage rate for the average car is 25 miles per gallon of gasoline. 2. The average car is driven 10,000 miles per year. 3. The United States has 150 million cars. 4. 10 percent of United States cars could be replaced with electric vehicles. (c) Some people have suggested that electric vehicles only shift the emission of air pollutants from dispersed sources to point sources. Explain and defend or refute this statement. (d) Propose two potential new United States government policies that would encourage the widespread use of electric vehicles. Explain.
Answers
It can be deduced that the environmental benefits of using electric vehicles are decreased levels of carbon monoxide and carbon dioxide.
What are the environmental benefits of using electric vehicles?
It improves human health by decreasing rates of headaches, drowsiness. A decrease means less global warming, decreased greenhouse effect, as well as decreased acid precipitation.
The potential reduction in petroleum consumption will be:
= (150 million cars) × (10,000 miles per year)/25 miles per gallon × 0.1
= 6 billion
Electric vehicles only shift the emission of air pollutants from dispersed sources because most electric cars are powered by an electrical generating source identified as using combustion such as fossil fuels and coal.
Some incentives that would encourage the use of electric vehicles include mandated production for electric vehicles, reduced tolls, etc.

If the nth term of a number sequence is 4n^2+ n find the first 3 terms and 10th term
Answers
Answer:
1st term = 7, 2nd term = 18, 3rd term = 39, 10th term = 403
Step-by-step explanation:
To find the 1st term substitute 1 for n in the equation:
4(1)² + 1 = (4 × 1) + 3 = 4 + 3 = 7
To find the 2nd term substitute 2 for n in the equation:
4(2)² + 3 = (4 × 4) + 3 = 16 + 3 = 18
To find the 3rd term substitute 3 for n in the equation:
4(3)² + 3 = (4 × 9) + 3 = 36 + 3 = 39
To find the 10th term substitute 10 for n in the equation:
4(10)² + 10 = (4 × 100) + 3 = 400 + 3 = 403

ground.
^ 3.0
Step-by-step explanation:
The ladder makes an angle, 0 with the
ground thus forming a right angle triangle
with the wall of the house.
The length of the ladder represents the
hypotenuse of the right angle triangle.
The ground distance from the base of the
wall to the foot of the ladder represents the
adjacent side of the right angle triangle.
Therefore, to determine how high up is the
top of the ladder on the wall, ×, we would

You move down 6 units. You end at (10, 4). Where did you start?
Answers
Answer:
(10,10)
Step-by-step explanation:
coordinates are (x,y)
x is horizontal(left and right), y is vertical (up and down)
going down 6 means subtracting 6 from the second number
lets reverse that to go up and add 6 back
4+6=10
so the original point was (10,10)
If you move DOWN, then that means you are moving in the "y" direction (up and down).
Thus, you are moving the unit "4" not "10". Since you are moving down, you must add to know where your starting position is. You add "4" and "6" together to make "10".
Answer:
You start at (10,10)
Find the solution of the system of equations. 3x-8y = 19

Answers
Step-by-step explanation:
the height from the 90° angle (which is y here) in a right-angled triangle is the square root of the Sergent lengths of the Hypotenuse.
y = sqrt(3×9) = 3×sqrt(3)
and x we get via Pythagoras :
x² = y² + 9² = 27 + 81 = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)
so, A is correct.
