Answer:
(-35) * (100 - 1)
Step-by-step explanation:
She was able to find the value of (-35) * 99 without using the missing 9 button on her calculator.
The easiest way to do this is to replace 99 with another set of numbers that has the same value as 99.
(100 - 1) has the same value as 99. So, Teena can replace 99 with (100 - 1):
(-35) * (100 - 1)
It will yield the desired result.

In football seasons, a team gets 3 points for a win, 1 point for a draw and 0 points for a loss. In a particular season, a team played 34 games and lost 6 games. If the team had a total of 70 points at the end of the season, what is the difference between games won and games lost?
Answer:
The difference between games won and games lost is 15.
Step-by-step explanation:
Since the team played 34 games and lost 6, the number of games where they got points is 28, therefore the number of wins plus draws, must be equal to that:
[tex]win + draws = 28[/tex]
Since each win values 3 points, while each draw values 1 point, then the number of points earned is given by:
[tex]3*win + draws = 70\\[/tex]
We now have a system of equations, which we can solve.
[tex]win + draws = 28\\3*win + draws = 70\\[/tex]
Multiplying the first equation by -1:
[tex]-win- draws = -28\\3*win + draws = 70[/tex]
Adding both equations:
[tex]2*win = 42\\win = 21[/tex]
Since the team won 21 games and lost 6, the difference is 15.
1) A camera costs £180 in a 10% sale. What was the pre-sale price
Answer:
£200
Step-by-step explanation:
Let the original price of the camera be x.
The 10% discounted price of the camera is £180. This means that 10% of x was deducted from x to give £180:
x - (10/100 * x) = 180
x - 0.1x = 180
0.9x = 180
x = 180 / 0.9 = £200
The pre-sale price was £200.

Answer:
(-9, 16)
Step-by-step explanation:
If (x, y) = (-9, 4), then (x, 4y) = (-9, 4·4) = (-9, 16).
A line that passes through the point (x,y), with a y intercept of band a slope of m, can be represented by the equation y = mx + b.
A line is drawn on the coordinate plane that passes through the point (3.-6) and has a slope of 4. The y intercept of the line is
Answer:
y = 4x - 18
Step-by-step explanation:
Write out y = mx + b.
The slope of the line in question is 4. Thus we have y = 4x + b.
Finally, substitute -6 for y, 3 for x and solve for b:
-6 = 4(3) + b, or -6 = 12 + b. Then b = -18, and the equation of this line is
y = 4x - 18
Answer:
18
Step-by-step explanation:
y=4x-18 is the solution and 18 is the y-intercept because the b (18) is the y-intercept.
What force is exerted on a test charge of 3.25 E−5 C, if it is placed in an electric field of magnitude 1.40 E4 N/C? Remember to identify all data (givens and unknowns), list equations used, show all your work, and include units and the proper number of significant digits to receive full credit.
Answer:
0.46 newtons
Step-by-step explanation:
For these kinds of problems, you can employ the formula
[tex]E=\dfrac{F}{q}[/tex]
where E represents the field in N/C, F represents the force in newtons, and q represents the charge in coulombs. You can therefore set up the following equation:
[tex]1.4\times 10^4 N/C=\dfrac{F}{3.25\times 10^{-5}C} \\\\[/tex]
[tex]F=(1.4\times 10^4 N/C) \times (3.25 \times 10^{-5} C)=4.6 \times 10^{-1} N[/tex] (following sig figs)

sally has a part time job mowing lawns so she can save money for a new car. she charges $5 per hour define the independent and dependent variables
Answer:
Independent: Amount of hours she works
Dependent: Amount of money she makes
Step-by-step explanation:
The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.
The dependent variable is what you measure in the equation. In this case, the amount of money she makes depends on the amount of time she works.

The sum of the digits of a two-digit number is 14. If the number formed by reversing the digits is less than the original number by 18. Find the original numbers.
Answer:
86
Step-by-step explanation:
1. a+b=14 ⇒ a= 14-b
2. 10a+b=18+10b+a ⇒ a= 2+b
comparing 1 and 2:
14-b= 2+b ⇒ 2b= 12 ⇒ b= 6
a= 14-b= 8
number = 86
reversed number = 68
Which two equations represent parallel lines?
A. Y=2x-5
B. Y=-1 over 2x +5
C. Y=1over2x-5
D. Y=2x+ 5
And why?
Answer:
A&D
Step-by-step explanation:
Lines with the same slope are parallel. 2x-5 and 2x+5 have the same slope
Answer:
A and D are parallel.
Step-by-step explanation:
Refer to the slope-intercept equation (y = mx + b).
M = the slope
If the slopes are equal, then the lines are parallel.
The slope for line A is 2, and so is the slope for line D.
Line A and line D are parallel.

You flip a coin.
What is P(not tails)?
Simplify your answer and write it as a fraction or whole number.
Answer:
1/2 or 0.5
Step-by-step explanation:
since there are two options, heads and tails, the probability of not flipping tails is 1/2, since the probability of flipping heads is 1/2
Answer:
1/2
Step-by-step explanation:
There are 2 sides of a coin.
Heads or Tails.
That means you have a 1/2 chance of getting tails. This also means you have 1/2 chance of not getting tails, in other words, getting heads.

7. Diana took 2 hours to cycle from town X to town Y. Her average speed was 10 kilometers per
hour.
a) Find the distance between the two towns. (2 marks)
b) If her average speed was increased by 2 kilometers per hour, how much time would she take
for the journey? (2 marks)
Answer:
a.) 20 kilometers
b.)1.67 hours
Step-by-step explanation:
a.) formula= speed =distance/time
Speed= 10km/hr
Distance=unknown
Time=2hrs
Therefore from formula, distance=speed x time
10 x 2
20 kilometers
b.) If average speed is increased by 2km/hr then
total speed= 2+10=12km/hr
Distance remains constant therefore distance= 20km
Therefore time =distance/speed
20/12
= 1.67 hours

Answer:
x = 67.5°
Step-by-step explanation:
A circle's angles add up to 360°
So,
x+3x+90 = 360
4x+90 = 360
4x = 360-90
4x = 270
Dividing both sides by 4
x = 67.5°
