Answer:
-278
Step-by-step explanation:
3 x 11 = 33
33 - 78 = -45
-45 x 6 = -270
-270 - 8 = -278
I think I might of did it wrong.... :C
Answer: The number is 14
Step-by-step explanation:
11x - 78 = 6x - 8
11x -6x = -8 + 78
5x = 70
x = 14

A man sold a bag for Rs 1,368 at 5% loss. Calculate her profit or loss percent if she had sold it for Rs 1,512.
help!!
Answer:
Profit %age = 6.55 %
Step-by-step explanation:
Selling Price = Rs 1,368
Loss % age = 5 %
Finding Cost Price:
Let Cost Price be x
So,
x = 1368 + 0.05x
x - 0.05x = 1368
0.95 x = 1368
=> x = Rs 1440
If he had sold it for Rs 1512, she would be having a profit of Rs 72
Profit %age:
Profit %age = [tex]Profit*100/CP[/tex]
Profit %age = 72 * 100 / 1440
Profit %age = 7200 / 1440
Profit %age = 5 %
Which equation can be used to find B in the triangle below? Right triangle A B C is shown. Side A B has a length of 6, side B C has a length of 10, and side A C has a length of 8. tangent B = Eight-tenths Tangent B = eight-sixths cosine B = Ten-sixths Cosine B = ten-eighths
Answer:
Tangent B = eight-sixths
Step-by-step explanation:
Data
AB: 6 unitsAC: 8 unitsFrom tangent definition:
tan(β) = opposite/adjacent
where β is some angle, and opposite and adjacent are the opposite and adjacent sides (or legs) to that angle.
In our case, B is the angle, opposite to angle B is side AC, and adjacent to angle B is side AB. Replacing with data:
tan(B) = AC/AB
tan(B) = 8/6

Helen Ming receives a travel allowance of $220 each from her company for time away from home. If this allowance in taxable and she has a 10% income tax rate, what amount will she have to pay in taxes for this employee benefit?
Initially I thought it was $22, but it says it's wrong.
Answer:
$33
Step-by-step explanation:
From the question, $22 is correct
If Helen Ming receives travel allowance of $220 from her company for time away from home
She has a 10% income tax rate
The amount she has to pay in taxes for the employee benefits is
10% of $220
10/100*$220
=0.1*$220
=$22
So you are correct
The only reason why you could be wrong is if the question is different from what you posted above just like the below question
Helen Ming receives a travel allowance of $220 each week from her company for time away from home. If this allowance is taxable and she has a 15 percent income tax rate, what amount will she have to pay in taxes for this employee benefit?
Here the amount she has to pay for the employee benefits is
15% of $220
15/100*$220
=0.15*$220
=$33

A gust of wind forces a rock to fall off a cliff that's 20 feet high. This is represented by the function h(t) = –16t2 + 20, where t represents the time measured in seconds, and h represents height above the ground. Approximate how many seconds it takes for the rock to hit the ground.
Answer Options:
A.) 1.25 seconds
B.) 1.5 seconds
C.) 1.12 seconds
D.) 1 second
Answer: C.) 1.12 seconds
Step-by-step explanation:
Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:
h (t) = –16t2 + 20
Solving for t (time)
0= –16t2 + 20
16t2=20
t2=20/16
t=√1.25 =1.12 seconds (option C)

∠A=5x−15 ∘ start color #11accd, angle, A, end color #11accd, equals, start color #11accd, 5, x, minus, 15, degrees, end color #11accd ∠ B = 2 x + 2 1 ∘ ∠B=2x+21 ∘
Answer: 45°
Step-by-step explanation:
Given that :
∠A=5x−15°---(1)
∠B=2x+21°----(2)
Equating
∠A = ∠B
(5x−15)° = (2x+21)°
5x - 15 = 2x + 21
Collecting like terms
5x - 2x = 21 + 15
3x = 36
x = 12
Substitute x = 12 in either angle A or B since both are congruent
∠A=(5x−15)°
∠A = (5(12) - 15)°
∠A = (60 - 15)°
∠A = 45°
∠A = ∠B = 45°
Use a graph to find the range of the function f(x) = 5/x^2
on the domain -5 < x < 5.
Answer:
Option A.
Step-by-step explanation:
The given function is
[tex]f(x)=\dfrac{5}{x^2}[/tex]
We need to find the range of the function f(x) on the domain [tex]-5\leq x\leq 5[/tex].
At x=-5,
[tex]f(-5)=\dfrac{5}{(-5)^2}=\dfrac{5}{25}=\dfrac{1}{5}[/tex]
At x=5,
[tex]f(5)=\dfrac{5}{(5)^2}=\dfrac{5}{25}=\dfrac{1}{5}[/tex]
As x approaches to 0, then the function approaches to positive infinity.
Draw the graph of given function as shown below.
In the graph x-axis represents the domain and y-axis represents the range.
From the graph it is clear that on the domain [tex]-5\leq x\leq 5[/tex] the value of function is greater than or equal to [tex]\dfrac{1}{5}[/tex].
So, range is [tex]f(x)\geq \dfrac{1}{5}.[/tex]
Therefore, the correct option is A.

Step-by-step explanation:
<DEF = 1/2 × 150°
<DEF = 75°
The measure of angle m<DEF is 75 degrees
The point where 2 lines meet is known as an angle.
Angles in a circle are created from the intersection of two or more lines. To get the unknown value from the circle geometry given, we will use the theorem that states that "the angle at the centre of a circle is twice the angle at the circumference"Angle at the centre = 150 degrees
Angle at the circumference = m<DEF
Using the theorem;

Answer:
y = (1/2)(x) + 1/2
Step-by-step explanation:
The x-intercept is (-1, 0) and the y-intercept appears to be (0, 1/2).
As we go from the x-intercept to the y-intercept, x increases by 1 and y increases by 1/2. Thus, the slope of the line is m = rise / run = 1/2.
Knowing that m = 1/2 and b = (0, 1/2), we can write the equation of this line in slope-intercept form as
y = (1/2)(x) + 1/2
A baseball team has won 7 less than 4 times
as many games as it has lost. It has lost n
games, so it has won 4n - 7 games.
If n is 26, what is 4n – 7?
Answer:
4n – 7 = 97 if n = 26
Step-by-step explanation:
Problem statement : If n is 26, what is 4n – 7
To solve this problem we will substitute 26 in place of n in 4n-7
Solving it
4*26 - 7
=> 104 -7 = 97
Thus, number of games won by the team is 97.

Eric throws a biased coin 10 times. He gets 3 tails. Sue throw the same coin 50 times. She gets 20 tails. Aadi is going to throw the coin once. 1. Which one of the following statements is, cotlrrect about the probability of Aadi getting Tails? A. Sue's estimate is best because she throws it 50 times. B. Sue's estimate is best because she gets more Tails. C. Sue's estimate is best because she throws it more times than Eric 2. Use Eric's and Sue's results to work out an estimate for the probability that Aadi will get Tails. Write out your fraction in the form a/b P. S WILL MARKS AS BRAINIEST AND THANK IF YOU ANSWER DECENTLY
Answer:
(1) Correct option (A).
(2) The probability that Aadi will get Tails is 0.40.
Step-by-step explanation:
The information provided is:
Eric throws a biased coin 10 times. He gets 3 tails.Sue throw the same coin 50 times. She gets 20 tails.The probability of tail in both cases is:
[tex]P(T|E)=\frac{3}{10}=0.30[/tex]
[tex]P(T|S)=\frac{20}{50}=0.40[/tex]
Here,
P (T|E) implies the probability of tail in case of Eric's experiment.
P (T|S) implies the probability of tail in case of Sue's experiment.
(1)
Now, it is given that Aadi is going to throw the coin once.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
In this case we need to compute the probability of Aadi getting Tails in a single toss.
As Sue uses a larger number of trials in the experiment, i.e. n = 50 > 30 times, according to the Central limit theorem, Sue's estimate is best because she throws it .
Thus, the correct option is (A).
(2)
As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:
[tex]P(\text{Aadi will get Tails})=P(T|A)[/tex]
[tex]=P(T|S)\\\\=0.40[/tex]
Thus, the probability that Aadi will get Tails is 0.40.
Answer:
The correct answer is C and 23/60
Step-by-step explanation:
Sue's estimate is best because she throws it more times than Eric.
This is because the more you throw a coin the more reliable the results will be compared to data from a coin that has been thrown less, therefore the answer is C.
For the second half you need to add the number of tails together to get you numerator and then add the amount of times the coin was thrown to get your denominator, (giving you 23/60)
Hope this helped :)
