Answer:
12
Step-by-step explanation:
Its 12 because when you do -16 + - 40.... then -12 you get =12 There you go
Step-by-step explanation:
Solution ,
Firstly we need to understand that
( - ) × ( - ) = ( + )
( + ) × ( + ) = ( - )
( - ) × ( + ) = ( - )
( + ) × ( - ) = ( - )
Question:
- 16 + ( - 12 ) - ( - 40 )
here ( + ) × ( - ) = ( - )
= - 16 - 12 - ( - 40 )
here ( - ) × ( - ) = ( + )
= - 28 + 40
here the ( + ) has greater variable so....
= + 12
hence 12 is the answer....
Isabel used integers to record her costs and earnings from face painting at a fair. she spent $25 on face-painting supplies. She earned $144 by painting faces.
How does Isabel record her costs and earnings?
Please help me ASAP
Answer:
-25 on painting supplies, +144 painting faces, +119 net gain
Step-by-step explanation:
spent = negative
earned = positive
net gain = earned - spent (sometimes it can be negative is you spend more than you make)

From inspection of the diagram, the problem has been modeled as a right triangle. Therefore, to find [tex]x[/tex] and [tex]y[/tex], use trigonometric ratios then compare to determine which distance is the smallest.
Trigonometric ratios
[tex]\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleH is the hypotenuse (the side opposite the right angle)To find [tex]x[/tex] use the sine trig ratio:
[tex]\implies \sf \sin(\theta)=\dfrac{O}{H}[/tex]
[tex]\implies \sin(47^{\circ})=\dfrac{x}{6}[/tex]
[tex]\implies x=6 \sin(47^{\circ})[/tex]
[tex]\implies x=4.39 \: \sf miles \:(2\:dp)[/tex]
To find [tex]y[/tex] use the cosine trig ratio:
[tex]\implies \sf \cos(\theta)=\dfrac{A}{H}[/tex]
[tex]\implies \cos(47^{\circ})=\dfrac{y}{6}[/tex]
[tex]\implies y=6 \cos(47^{\circ})[/tex]
[tex]\implies y=4.09 \: \sf miles \: (2 \: dp)[/tex]
As 4.09 < 4.39, ship 2 is currently closer to the coast guard.

What are the solutions of the equation y = -2x square + 9x - 4
Answer:
x = (-1±i√3)/2
Step-by-step explanation:
y = -2x² + 9x - 4
x = (-b±√(b²-4ac))/2a
x = (2±√((-2)²-4(-1)(-4))/2(-2)
x = (2±√(4-16))/-4
x = (2±√-12)/-4
√-12 = √12 x √-1
√12 = √4√3

A few years ago, Simon Powell purchased a home for $200,000. Today, the home is worth $350,000. His remaining mortgage balance is $150,000. Assuming that Simon can borrow up to 80 percent of the market value, what is the maximum amount he can currently borrow against his home?
The maximum amount Simon Powell can borrow against his home is $130,000.
How to calculate the maximum amount that can be borrowed against a homeThe maximum amount Simon Powell can borrow against his home can be calculated using the following formula:
Maximum amount that can be borrowed = (Current value of the home * Percentage of the market value that can be borrowed) - Mortgage balance …………………. (1)
Substituting all the relevant values into equation (1), we have:
Maximum amount that can be borrowed = ($350,000 * 0.80) - $150,000 = $130,000

fine the value of x in this screenshot
Answer:
x = 125º
Step-by-step explanation:
Angles in a triangle add to 180º so:
180 - 42 - 83 = 180 - 125 = 55º
Angles on a straight line also add to 180º so to find x:
180 - 55 = 125º
x = 125º

The point (2,5) is represented on the graph. Which point also belongs on this graph?
If the point (30, 75) satisfies the equation, then the point will lie on the line. Then the correct option is B.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The point (2,5) is represented on the graph.
Then the equation of the line passing through (2, 5) and the origin will be given as
y - 0 = [(5 - 0) / (2 - 0)] (x - 0)
y = 5/2 x
2y = 5x
If the point (30, 75) satisfies the equation, then the point will lie on the line.
2 × 75 = 5 × 30
150 = 150

Malachy rolls a fair dice 168 times.
How many times would Malachy expect to roll a number greater than 5?
Answer:

Step-by-step explanation:
On a fair die, the probability of rolling a 6, the only number greater than 5, is 1/6. So in 168 rolls of this die, Malachy can expect a 6 on 1/6 × 168, or 28 times.
The two stadiums with the largest capacity is are Marshfield Stadium and Browden stadium. The capacity of Marshfield Stadium exceeds that of Bowden by 4,465 people. Combined, the two stadiums have a capacity of 210,355 people. Find the capacity of each stadium.
Step-by-step explanation:
x = capacity of Marshfield
y = capacity of Browden
x + y = 210,355
x = y + 4,465
so, using the second equation in the first
(y + 4,465) + y = 210,355
2y + 4,465 = 210,355
2y = 205,890
y = 102,945 (Browden)
x = y + 4,465 = 102,945 + 4,465 = 107,410 (Marshfield)

Money needed to raise $1000, sell a dozen of cookies for $3 a dozen. how many dozen of cookies need to be sold to raise $1000?
Answer:
334 dozen cookies.
Step-by-step explanation:
1000=3x
Let x = dozen of cookies sold
3x=1000
x=1000/3
x=333.33
Since 333.33 isn't a whole number, we need to round it up to 334 since rounding it down to 333 won't raise 1000 dollars.

NEED HELP ASAP!!! 20 POINTS!!!!
Answer:
Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by
surface area of prism = 2 * area of base + perimeter of base * H
So for the rectangular prism in your example..
surface area = 2LW + 2(L+W)H
= 2 * 7 * 4 + 2*(7+4)*5
= 56 + 2 * 11 * 5

Which of the following is a quadratic equation that has the roots x = 2 and x = −7? (4 points)
Answer:
x^2 + 5x - 14
Step-by-step explanation:
We can assume that if there is 2 options for x, this is a quadratic equation that equals 0.
Therefore, we can put this into brackets as one bracket must equal 0.
(x - 2) (x + 7)
After this we expand, which is a process easier to search up
The answer is:
x^2 + 7x - 2x - 14
We can simplify this to:
x^2 + 5x - 14
x^2 represents x squared in case you were wondering
Therefore, the answer is:
x^2 + 5x - 14
the time taken, t, for a journey of fixed distance is inversely proportional to the average speed of travel, s. If the journey takes 2 hours 15 minutes travelling at an average speed of 50km/hour, how long will it take if the average speed is 27km/hour. Give your answer in hours and minutes
[tex]\huge{\color{red}{\fbox{\textsf{\textbf{Answer}}}}} [/tex]
4 hours 12 minutes
Step-by-step explanation:
We need to convert time in hours by diving 15 by 60
[tex] \sf 2 \frac{15}{60} \\ \\ \sf 2 \frac{1}{4} [/tex]
as it is mixed fraction we will convert into improper
[tex] \sf \frac{(2 \times 4) + 1}{4} \\ \\ \sf time = \frac{9}{4} hours[/tex]
Now we need to find distance
[tex] \sf \green {distance = speed \times time}[/tex]
Here speed is 50km/h
[tex] \sf \implies distance = 50 \times \frac{9}{4}km \\ \\ \sf \implies distance = \frac{25 \times 9}{2}km \\ \\ \sf \implies distance = \frac{225}{2} km \\ \\ \sf \implies \red {distance = 112.5km}[/tex]
Now we have to have time at new speed at 27km/h
and distance is same
[tex] \sf \pink{ time = \frac{distance}{speed} }[/tex]
Now substituting the value of speed and distance
[tex] \sf \implies time = \frac{112.5}{27} [/tex]
Now we will remove point(.) from the distance by multiplying 10 with 27
[tex] \sf \implies time = \frac{1125}{27 \times 10} \\ \\ \sf \implies time = \frac{41.6}{10} [/tex]
now we will convert it into mixed fraction
[tex] \sf \implies time = 4 \frac{1}{5} hours [/tex]
Now we will convert fraction hours into minutes by multiply with 60
[tex] \sf \implies time = 4 \: hours \: \frac{1}{5} \times 60 \: minutes \\ \\ \sf \implies \orange{ time = 4 \: hours \: 12 \: minutes}[/tex]
Find the measure of B
Answer:
<B = 52°
Step-by-step explanation:
The triangle is 180° Angle A and B add up to 118°
4y° + (3y + 7)° = 112°
7y + 7 = 112°
7y = 105
y = 15
Since you solve for y, plug your y into the angles to solve.
<B = 3y + 7
<B = 3 * 15 + 7
<B = 45 + 7
<B = 52°
