Kelly bought a computer that was 20% off the regular price of $1,060. If a 7% sales tax was added to the cost of the computer, what was the total price Kelly paid for it?
Answer: $ 1361.04
Step-by-step explanation:
Discount will be 1060 * 20% = 212
Sales price 1060 + 212 = 1272
Tax 7% = 89.04
Kelly paid 1272 + 89.04 = 1361.04
Solve for x
x/5 + 1 = 7
Steps:
Step 1: Simplify both sides of the equation.
1 /5x+1=7
Step 2: Subtract 1 from both sides.
1/5x+1−1=7−1
1/5x=6
Step 3: Multiply both sides by 5.
5*(1/5x)=(5)*(6)
Description:
Since we are solving for x first steps is to Simplify both sides of the equation. Then subtract 1 from both sides. After that multiply both sides by 5 and you will get your answer. The correct answer for this question is x=30.
Answer: x=30
Please mark brainliest
Hope this helps.
The value of x from the given equation is 30.
The given equation is x/5 +1=7.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, x/5 +1=7
Transpose 1 to other side of the equation, we get
x/5 =7-1
x/5 = 6
Transpose 5 to other side of the equation, we get
x = 6×5
x = 30
Therefore, the value of x from the given equation is 30.

Simply the expression [tex]\frac{x-7}{3} - \frac{5-x}{2}[/tex]
Answer: [tex]\frac{5x-29}{6}[/tex]
Step-by-step explanation:
To simplify the equation, we can just subtract the 2 fractions. First, we need to make sure they have a common denominator.
[tex]\frac{2(x-7)}{6} -\frac{3(5-x)}{6}[/tex]
Now that the fractions have the same denominator, we can distribute the numerator and subtract.
[tex]\frac{2x-14}{6} -\frac{15-3x}{6} =\frac{2x-14-15+3x}{6} =\frac{5x-29}{6}[/tex]

All else being equal, a study with which of the following error ranges would be
the most reliable?
A. +-6 percentage points
B. +-15 percentage points
C. +-9 percentage points
D.+- 112 percentage points
The study with an error range of +-6 percentage points would be the most reliable.
As larger error ranges, such as options B, C, and D, indicate a greater degree of uncertainty and variability in the dat This reduces the reliability and precision of the study's findings.
So, when all other factors are equal, a study with a smaller error range, like with +-6 percentage points, would be considered more reliable.
Thus, with an error range of +-6 percentage points, has the smallest range.

There are 130 people in a sport centre. 73 people use the gym. 62 people use the swimming pool. 58 people use the track. 22 people use the gym and the pool. 29 people use the pool and the track. 25 people use the gym and the track. 11 people use all three facilities. A person is selected at random. What is the probability that this person doesn't use any facility
To find : Probability that person doesn't use any facility
Given : Total people = 130 ; People using gym (G), Swimming Pool (S), Track (T) = 73, 62, 58 respectively. People using G & P, P & T, G & T = 22, 29, 25. People using P & G & T = 11
So : Prob (G) = 73/ 130 , Prob (S) = 62/130 , Prob (T) = 58/130
P (G ∩ P) = 22 / 130 , P (P ∩ T) = 29 / 130 , P (G ∩ T) = 25 / 130 , P (P ∩ G ∩ T) = 11 / 130
Prob [ Person uses either P or G or T ] :
P (PUGUT) = P(G) + P (S) + P (T) - P (G ∩ P) - P (P ∩ T) - P (G ∩ T) - 2 P (P∩G∩T) = ( 73 + 62 + 58 - 22 - 29 - 25 - 22) / 130 = 95 / 130
Prob [Person uses neither P or G or T] : 1 - Pr [Person uses either P or G or T] = 1 - P (PUGUT) = 1 - (95 / 130) = 35 / 130
Hence, Probability that person doesn't use any facility = 35 / 130

What is the decimal multiplier to increase by 99%?
Answer:To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2.
Step-by-step explanation:
The decimal multiplier of a number to increase by 99% will be 1.99.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Let's consider the number x.
To increase it by 20% we need to find 20% of it so 0.20x
Now, add this 20% to x so that it will increase by 20% as,
0.20x + x = 1.20x
Thus,to increase the number by 20% we need to multiply 1.20
Similarly to increase a number by 99% we need to multiply with 1.99.
Hence "The decimal multiplier of a number to increase by 99% will be 1.99".

At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
r + f ≥ 16
4r + 2f ≤ 40What is the maximum number of ride tickets she can buy?
Answer:
The maximum number of ride tickets is 4
Step-by-step explanation:
r = number of ride tickets
f = number of food tickets
r + f ≥ 16
4r + 2f ≤ 40
Using these as equations
f = 16 -r
Using this in the second equation
4r+ 2 (16 -r) = 40
4r +32 -2r = 40
2r +32 = 40
2r = 8
r = 4
The maximum number of ride tickets is 4

The names of 5 boys and 5 girls are in a hat. What is the probability of first drawing a girl’s name and then a boy’s name from the hat?
Answer:
9/20
Step-by-step explanation:
The probability of drawing a girl's name is 0.5, since there are 5 girls in 10 kids here. If that girl's name is not replaced, then the probability of drawing a boy's name is 5/9, since there are still such names but the total number of names is now 9.
Thus, the probability of this joint event is (0.5)(9/10) = 4.5/10 = 9/20
Answer:
so drawing a girls name from the hat would be 5/10 since 5 girls are there out of 10 students in total. After, you pick the girls name the total number of student names would become 9 and since there are 5 guys, you get a 5/9 probability

Answer:
24.49 units
Step-by-step explanation:
The circumference of the circle is 153.86 units.
The circumference of a circle is given as:
C = 2 * pi * r

Therefore:
r = C / (2 * pi)
=> r = 153.86 / (2* pi) = 24.49 units
