Alexandra buys sweatshirts for $12 each. In her store, she sells each sweatshirt for $30.
Part B
During a clearance sale, Alexandra discounts the Halloween sweatshirts by 55%. What is the percentage of profit Alexandra will make on each Halloween sweatshirt she sells? Show your work or explain your answer.
Please and thank you!! And please if you can explain how you got the answer.
Answer:
A is 360
Step-by-step explanation:
Answer:
Step-by-step explanation:
Multiply $30 by .25 you get, it's $7.50so you subtract $7.50 from $30 and you get $22.50. Then multiply 2 (sweaters) by $22.50 and you get $45,but wait you still have to multiply that sales tax so you multiply .04 by $45 and you get $1.80, later you subtract $1.80 from $45 and you get $43.20(the cost of the two sweaters) I did part1 only cuz' no I have no time left Sorry for the inconvenience
There are 486 hamsters at a private showing of a new documentary about humans. If there are 12 seats in each row, about how many rows will the hamsters fill? Choose the best estimate.
A. 20
B.4
C.40
D.60
Answer:
C, 40
Step-by-step explanation:
If there are 12 seats in each row, and 486 hamsters total, then we can safely assume one hamster takes up one seat.
To find out how many rows they can take, we need to divide the number of hamsters by the number of seats to get 486 / 12 approximately equals 40.
Answer:
C.
Step-by-step explanation:
Take the first two numbers of 486.
How many times does 12 fit into 48?
4 times.
Since all of the estimations do not have any form of individual single digits (as they do normally), we would dismiss the 6 and use its place just as a '0.'
40.

In ABC, mC = 30 and a = 8. If the area of the triangle is 12, what is the length of side b?
show work pls
9514 1404 393
Answer:
b = 6
Step-by-step explanation:
The area is given by the formula ...
Area = 1/2·ab·sin(C)
12 = (1/2)(8)b·(1/2) . . . . . fill in the given values
12 = 2b . . . . . . . . . . . simplify
6 = b . . . . . . . . . . . divide by 2
The length of side b is 6 units.

Answer: x = 2.5
Explanation:
5.2 * 9.3 * x = 120.9
120.9 / 5.2 = 9.3 * x
23.25 = 9.3 * x
23.25 / 9.3 = x
x = 2.5

o Line UR and Line QS are parallel.
o ZQRT and ZT RU are supplementary.
O Line TX and Line OS are perpendicular.
The measure of ZSW X is 108.
Based on the linear pair postulate, the statement that is true is: D. m∠SWX = 108°.
What is the Linear Pair Postulate?According to the linear pair postulate, the sum of angles that form a linear pair equals 180 degrees.
72° and ∠SWX are a linear pair. Therefore:
m∠SWX = 180 - 72
m∠SWX = 108°
The statement that is true is: D. m∠SWX = 108°

Answer:
see belowStep-by-step explanation:
Question-6:we are given a equation
[tex] \sf \displaystyle \: \log_{4}( - x) + \log_{4}( 6 - x) = 2[/tex]
to solve so
recall logarithm multiplication law:
[tex] \sf \displaystyle \: \log_{4}( - x \times (6 - x)) = 2[/tex]
simplify multiplication:
[tex] \sf \displaystyle \: \log_{4}( - 6 x + {x}^{2} ) = 2[/tex]
remember [tex]\displaystyle \log_{4}(4^2)=2[/tex]
so
[tex] \sf \displaystyle \: \log_{4}( - 6 x + {x}^{2} ) = \log_{4}( {4}^{2} ) [/tex]
cancel out [tex]\log_4[/tex] from both sides:
[tex] \sf \displaystyle \: - 6 x + {x}^{2} = {4}^{2} [/tex]
simplify squares:
[tex] \sf \displaystyle \: - 6 x + {x}^{2} = 16[/tex]
move left hand side expression to right hand side and change its sign:
since we are moving left hand side expression to right hand side there'll be only 0 left in the left hand side
[tex] \sf \displaystyle \: - 6 x + {x}^{2} - 16 = 0[/tex]
rewrite it to standard form i.e ax²+bx+c=0
[tex] \sf \displaystyle \: {x}^{2} - 6x - 16 = 0[/tex]
rewrite -6x as 2x-8x:
[tex] \sf \displaystyle \: {x}^{2} + 2x - 8x - 16 = 0[/tex]
factor out x and 8:
[tex] \sf \displaystyle \: x {(x}^{} + 2) - 8(x + 2) = 0[/tex]
group:
[tex] \sf \displaystyle \: (x - 8){(x}^{} + 2) = 0[/tex]
[tex] \displaystyle \: x = 8 \\ x = - 2 [/tex]
[tex] \therefore \: x = - 2[/tex]
Question-7:move left hand side log to right hand side:
[tex] \displaystyle \: \log(x ) + \log(x - 21) = 2 [/tex]
use mutilation logarithm rule;
[tex] \displaystyle \: \log( {x}^{2} - 21x) = 2 [/tex]
[tex]\log(10^2)=2[/tex] so
[tex] \displaystyle \: \log( {x}^{2} - 21x) = \log({10}^{2} )[/tex]
cancel out log from both sides:
[tex] \displaystyle \: {x}^{2} - 21x = 100[/tex]
make it standard form:
[tex] \displaystyle \: {x}^{2} - 21x - 100= 0[/tex]
factor:
[tex] \displaystyle \: {(x} + 4)(x - 25)= 0[/tex]
so
[tex] \displaystyle \: x = 25[/tex]

The table shows the proportional relationship between the number of computers
a company sold, x, and the profit that the company made, y. The profit, y, can be
written in terms of x, the number of computers sold: y = What expression
completes the equation?
Profit on Sales
Number of Computers Sold
Profit (dollars)
3
450
7
1050
11
1650
15
2250
Answer:
y = 150x
Step-by-step explanation:
There is a proportional relationship between number of computers sold (x) and profit generated (y)
y ∝ x
y = kx
Here, k = proportionality constant
From the table given,
At y = 450 and x = 3,
450 = k(3)
k = 150
Therefore, expression that represents the proportional relationship will be,
y = 150x

Show Your Reasoning.
Answer:
[tex]4\frac{19}{24}[/tex]
Step-by-step explanation:
I hope I did this right:
So first thing to do is set up the equation.
[tex]K + \frac{1}{3} = 5\frac{1}{8}[/tex]
Next thing to to is subtract 1/3 from both sides to get:
[tex]K = 5\frac{1}{8} - \frac{1}{3}[/tex]
Next up, you will multiply each of the fractions by the opposing value
(multiply 1/8 by 3 and 1/3 by 8)
[tex]K = 5\frac{3}{24}[/tex][tex]-\frac{8}{24}[/tex]
Alright almost done, by multiplying 24 by 5 you get 120, that will go in the numerator to make the math a lot easier.
K = [tex]\frac{123}{24}[/tex][tex]-\frac{8}{24}[/tex]
Finally, you subtract 123 over 24 by 8 over 24.
K = [tex]\frac{123}{24} - \frac{8}{24} = \frac{115}{24}[/tex]
Then just simplfy the 115/24 to get
[tex]4\frac{19}{24}[/tex]

Plzz I asked this three times! The Functions r and s are defined as follows.
r(x)=-2x+2
s(x)=x^2+2
Find the value of s(r(2)).
Answer:
s(r(2)) = 6
Step-by-step explanation:
You would first solve for r(2). You then input r(2) which equals -2 into s(r(2)).
r(x)= -2x + 2
r(2)= -2(2) + 2
r(2)= -4 +2
r(2)= -2
s(x)=x² + 2
s(r(2)) = (-2)² +2
s(r(2)) = 6

a team of 10 players is to be selected from a class of 6 girls and 7 boys. match each scenario to its probability
Step-by-step explanation:
The selection of r objects out of n is done in
many ways.
The total number of selections 10 that we can make from 6+7=13 students is
thus, the sample space of the experiment is 286
A.
"The probability that a randomly chosen team includes all 6 girls in the class."
total number of group of 10 which include all girls is C(7, 4), because the girls are fixed, and the remaining 4 is to be completed from the 7 boys, which can be done in C(7, 4) many ways.
P(all 6 girls chosen)=35/286=0.12
B.
"The probability that a randomly chosen team has 3 girls and 7 boys."
with the same logic as in A, the number of groups were all 7 boys are in, is
so the probability is 20/286=0.07
C.
"The probability that a randomly chosen team has either 4 or 6 boys."
case 1: the team has 4 boys and 6 girls
this was already calculated in part A, it is 0.12.
case 2, the team has 6 boys and 4 girls.
there C(7, 6)*C(6, 4) ,many ways of doing this, because any selection of the boys which can be done in C(7, 6) ways, can be combined with any selection of the girls.
the probability is 105/286=0.367
since case 1 and case 2 are disjoint, that is either one or the other happen, then we add the probabilities:
0.12+0.367=0.487 (approximately = 0.49)
D.
"The probability that a randomly chosen team has 5 girls and 5 boys."
selecting 5 boys and 5 girls can be done in
many ways,
so the probability is 126/286=0.44

Step-by-step explanation:
Given the Trapezoid ABCD
Find the length of AD
Pls hellpppp
Given:
In trapezoid [tex]ABCD, AD\parallel BC, MN[/tex] is the mid-segment of [tex]ABCD, AD=30x-10,MN=31x+1,BC=30x+28[/tex].
To find:
The length of [tex]AD[/tex].
Solution:
We know that the length of the mid-segment of a trapezoids is half of the sum of lengths of two parallel sides of the trapezoid.
In trapezoid [tex]ABCD[/tex],
[tex]MN=\dfrac{AD+BC}{2}[/tex]
[tex]31x+1=\dfrac{30x-10+30x+28}{2}[/tex]
[tex]31x+1=\dfrac{60x+18}{2}[/tex]
[tex]31x+1=30x+9[/tex]
Isolate variable terms.
[tex]31x-30x=9-1[/tex]
[tex]x=8[/tex]
Now,
[tex]AD=30x-10[/tex]
[tex]AD=30(8)-10[/tex]
[tex]AD=240-10[/tex]
[tex]AD=230[/tex]
Therefore, the length of [tex]AD[/tex] is 230.
