Can someone help me out with this ??
Answer:
1. b > -2
2. x <= 3
Step-by-step explanation:
Question 1:
-2(b + 5) < -6
Divide both sides by -2. Remember to change the inequality sign.
b + 5 > 3
Subtract 5 from both sides.
b > -2
Question 2:
-(x - 10) >= 7
Divide both sides by -1. Remember to change the inequality sign.
x - 10 <= -7
Add 10 to both sides.
x <= 3
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)

The amount of money, in dollars, Sarah has in her savings account is modeled as a function of time in months. This function is represented by the graph below. What is the average rate of change for the amount of money, in dollars per month, from month 0 to month 12? A $25 per month B $50 per month C $300 per month D $500 per month
Answer:
The average rate of change for the amount of money is A) $25 per month
Step-by-step explanation:
From the graph we can see Sarah earn $50 every two months, 50/2 = 25/1 so we can determine Sarah's average rate of change from month 0 to month 12 is $25 dollars per month. Hope this helped, let me know if you have any questions! :)
A fair 6 sided die is rolled five times. What is the probability that the sequence of rolls is 4,6,1, 5, 3?
Answer:
Probability = 1/7776
Step-by-step explanation:
We know that probability is given by:
Probability = No. of Desirable outcomes / Total no. of outcomes.
If a die is rolled 5 time, we need to find the probability that the sequence of rolls is 4, 6, 1, 5, 3.
If a die is rolled first time, the probability that it will get 4 is:
Probability (4) = 1/6
Similarly if a die is rolled second time, the probability that it will get a 6 is:
Probability (6) = 1/6
Similarly the probability of each number on each roll is 1/6
To find the collective probability of 5 rolls, we'll multiply all the 5 probabilities to get the answer.
Probability = P(4) · P(6) · P(1) · P(5) · P(3)
Probability = 1/6 · 1/6 · 1/6 · 1/6 · 1/6
Probability = 1/7776
CORRECT ANSWER GETS A BRAINLIEST
Answer:
B. N(c) = (c-20)/n
Step-by-step explanation:
Given
C(n) = 10n+20
we have to find the inverse of this function
we have to express n in terms of C(n)
C(n) = 10n+20
we have make n independent of n and remove any other term containing on the side of n
subtracting 20 from LHS and RHS
C(n) - 20 = 10n+20 - 20
C(n) - 20 = 10n
dividing LHS and RHS by 10
C(n)/10 - 20/10 = 10n/10
=> n = (C(n) - 20)/10
Now given in problem, N(c) is no of bushels picked
and c is the cost of apple
so in function n = C(n) - 20/10
we replace C(n) with c
and n with N(c)
and then we have
N(c) = (c-20)/n Answer

The solution of the given equation will be y = -14/13
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
We are given the equation as;
10y+11=25−3y
We need to solve for y;
10y+11=25−3y
10y =25−3y - 11
10y =−3y - 14

When the outlier(s) are removed, how does the mean change? dot plot with 1 dot over 15, 1 dot over 23, 1 dot over 24, 1 dot over 25, 1 dot over 26, 1 dot over 27, and 1 dot over 35 The mean doesn't change. The mean increases by 2. The mean decreases by 2. There are no outliers.
Answer:
C
Step-by-step explanation:
The mean will increase by 2. The outlier is 15. When you remove it, the mean will increase.
With the outliers the mean is 25, how?
well if we put down the numbers 15,23,24,25,26,27,35 and add them together 15+23+24+25+26+27+35 we get 175 now we have to divide by how many numbers are there 175/7=25. That is the mean WITH the outliers.
Now, WITHOUT the outliers. The outliers are 15 and 35. We know this because, there is a huge gap between 15 and 23, and 27 and 35. We basically do the same thing but without the outliers. 23+24+25+26+27=125 we divide by how many numbers are there 125/5 then we get 25.
So the answer is A-The mean doesn't change

Work out the size of angle DEF, You must give a reason for your answer (Angles are on the picture below)
Answer:
420°
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;
150 = 2m<DEF
m<DEF = 150/2
m<DEF = 75degrees
Hence the measure of angle m<DEF is 75 degrees

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.
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 %

In DEF,the measure of F=90, FD=75 feet, and EF=95 feet. Find the measure of D to the nearest tenth of a degree
Answer:
The found angle D is:
D = 51.7°
Step-by-step explanation:
We have a right angle triangle with the right angle at F.
The given right angle triangle is shown in the diagram below.
EF = 95ft ⇒ Perpendicular of the triangle
FD = 75 ft ⇒ Base of the triangle
We have to find angle D.
Lets find angle D by using tan.
We know that
tan D = Perpendicular of the triangle / Base of the triangle
tan D = 95/75
D = tan⁻¹ (95/75)
D = 51.70983°
Rounding off the found angle to nearest 10th of a degree.
D = 51.7°
