An item had an original price of $5.00. It had a percent markup of 45%. What was the value of the markup?
Answer:
markup price = $2.25
Step-by-step explanation:
markup = 45% of $5
markup = 45/100 x 5
markup = $2.25
selling price = $5 + $2.25
selling price = $ 7.25

Solve for x:
(-3/2)x-9=-27
- 24
-12
11
12
i love these kind of questions :D
okay so lets write our problem down 1st:
(-3÷2)x-9=27
okay so you take one of your answers lets do A 1st and put is as x like this:
(-3÷2)-24x(-9)=27 now solve:
(think of PEMDAS)
P = perenthesis
E = exponents (which you dont have in this problem)
M = multiply
D = divide
A = add
S = subtract
do perenthesis 1st which would be (-3÷2)
(-1.5)-24x(-9)
now multiply 24x(-9)
(-1.5)-216 = (-214.5) does it equal -24 (which was what you plugged in for x)
no it doesnt so A cant be your answer. now do it for the rest of your answers :D
15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?
Answer:
annual rate: r = 0.068
Step-by-step explanation:
The formula is r(t) = P(1+r)^t
Since the time is already in years we just have to solve for the rate
1 + r = 1.068
r = 0.068
The rate of change in the value of account is 0.068
What is rate of change?
'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'
According to the given problem,
Annual rate:
r = 0.068
The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]
Therefore, solving for the rate
⇒ 1 + r = 1.068
⇒ r = 0.068

find the coordinates of point which divides the line segment joining the points (a+b,a-b) and (a-b,a+b) in the ratio 3:2 interally
Answer:
Coordinate of 0 = [tex]\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)[/tex]Step-by-step explanation:
Let AOB be the line segmentPoint 'O' divides the line segment into m:n = 3:2Given:
Coordinate of a = (a+b, a-b)Coordinate of b = (a-b, a+b)Ratio = 3:2ToFind:
Coordinate of 0 (zero)Solution:
ATQ,
[tex]\dfrac{m}{n}=\dfrac{3}{2}[/tex]Coordinate of a = (x[tex]_{1}[/tex], y[tex]_{1}[/tex])Coordinate of b = (x[tex]_{2}[/tex], y[tex]_{2}[/tex])As we know that,
[tex]\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}[/tex]
[tex]\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}[/tex]
[tex]\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}[/tex]
[tex]\implies\:\:\red{x = \dfrac{5a - b}{5}}[/tex]
Similarly,
[tex]\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]
[tex]\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}[/tex]
[tex]\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}[/tex]
[tex]\implies\:\:\red{y = \dfrac{5a+b}{5}}[/tex]
Hence,
Coordinate of 0 is [tex]\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}[/tex]

A softball team has 12 girls on it. The coach needs to arrange 9 girls for the batting order. If the lineup is selected at random, what is the probability that you will be the lead-off batter (the first person to bat)?
Answer: P = 1/12 = 0.083
Step-by-step explanation:
Out of the 12 girls, there will be only one that is the lead-off batter.
we can assume that this is the first being selected at random, then the probability that you will be the lead-off batter, is equal to the quotient between 1 (the outcome where you are selected) and 12 (the total number of outcomes)
Then the probability is:
P = 1/12 = 0.083
The fact that there will be an arrange of only 9 girls does not affect the probability of you getting the position of the lead-off batter.

Answer:-3<y<2
The answer should be D
which equation is represented by this graph?
A. y = 2/3x - 2
B. y = 2/3x + 3
C. y = 3/2x - 2
D. y = 3/2x + 3
3/2x-2
C. it should be this one
9514 1404 393
Answer:
A. y = 2/3x - 2
Step-by-step explanation:
The line intersects the y-axis at -2, so eliminates choices B and D, which have y-intercepts of +3.
The line has a rise of 2 grid squares for a run of 3 grid squares, so has a slope of ...
m = rise/run = 2/3 . . . . . eliminates choice C
The appropriate choice is the one with a slope of 2/3 and a y-intercept of -2:
A. y = 2/3x - 2
