Answer:
Number of T-SHIRT sold = x = 110
Number of sweatshirt = y = 40
Step-by-step explanation:
Let
Number of T-SHIRT sold = x
Number of sweatshirt = y
The number of T-shirts sold was 10 fewer than three times the number of sweatshirts sold.
x = 3y - 10
Cost of each T-SHIRT = $11
Cost of sweatshirt = $19
Total cost = $1,970
Total = x + y
1,970 = 11(3y - 10) + 19y
1970 = 33y - 110 + 19y
1970 + 110 = 33y + 19y
2080 = 52y
y = 2,080/52
y = 40
Substitute y = 40 into
x = 3y - 10
x = 3(40) - 10
x = 120 - 10
x = 110
Number of T-SHIRT sold = x = 110
Number of sweatshirt = y = 40
Answer:
110

[tex]x = \frac{22}{3}[/tex]
Step-by-step explanation:
Since both CB and ED intersect AD perpendicularly, we can say they are parallel and that ΔACB is similar to ΔAED from Thales intercept theorem. Now, we can set up a proportion from the definition of similar triangles:
[tex]\frac{AB}{AD} = \frac{BC}{DE}[/tex]
We can say that AD = AB + BD(segment addition postulate) and substitute to get AD = 11. Now we can plug in the numbers we have to the proportion:
[tex]\frac{6}{11} =\frac{4}{x}[/tex]
We can cross-multiply to get:
[tex]6x = 44[/tex]
and divide by 6 to get
[tex]x = \frac{22}{3}[/tex]

The population of a city can be modeled by the expression P(1.06)^t where T represents the number of years since 1990 and P represents the population in 1990. Which statement is correct
Answer:
D. the yearly growth rate of the population is 6%
Step-by-step explanation:
Given the exponential growth function : P(1.06)^t
Recall the general form of the function :
P(t) = P0(1 + r)^t
Where, P0 = Initial population ; r = rate ; t = time
Comparinv the equation and the function Given :
We can Evaluate :
1 + r = 1.06
r = 1.06 - 1
r = 0.06
To percentage :
0.06 * 100%
= 6%

Max went to a shopping mall with $45 in his wallet. He spent 4/5 of the money he had in his wallet at the bookstore. How much money, in dollars, did he have left? *
Answer:
Amount of money Max have left = $9
Step-by-step explanation:
Given:
Amount of money Max had = $45
Part pf money spend by max = 4/5
Find:
Amount of money Max have left
Computation:
Amount of money spend by Max = [Amount of money Max had][Part pf money spend by max]
Amount of money spend by Max = [45][4/5]
Amount of money spend by Max = [9][4]
Amount of money spend by Max = $36
Amount of money Max have left = Amount of money Max had - Amount of money spend by Max
Amount of money Max have left = 45 - 36
Amount of money Max have left = $9

Explain what the equation 3x = 6 means without using the word equal. Explain why 2 is a solution of the equation.
Answer:
See explanation
Step-by-step explanation:
Given
[tex]3x = 6[/tex]
Solving (a): What the expression means
3 when multiplied by x, gives 6
Solving (b): Why 2 is the solution
We have:
[tex]3x = 6[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} = \frac{6}{3}[/tex]
[tex]x = \frac{6}{3}[/tex]
[tex]x = 2[/tex]

Given the parallelogram, solve for x and find the measure of segment WX
Answer:
The answer is 17.
Step-by-step explanation:
Since it's a parallelogram, VY = WX.
Therefore, [tex]5x + 2 = 6x - 1[/tex].
Solving for x we get: [tex]x = 3[/tex]
To get the measure of segment WX, substitute [tex]x = 3[/tex] back into the side [tex]6x - 1[/tex]. Therefore [tex]6x - 1 = 6(3) - 1 = 17[/tex]

Ezgi's mom took Ezgi and her five friends to the circus for her birthday party. Her mom got a $12.50 ticket
and the same snack for each child from the concession stand. She paid $105 for all of the tickets and
snacks.
Which equations represent this situation, where s represents the cost of one snack in dollars?
Select all that apply.
Answer:
5*(s+12) = $105
Step-by-step explanation:
5 snacks + 5 tickets makes the total 105 so the equation
5*(s+12) = $105 is the answer to the question.

(a) Construct, using a compass and straightedge, the midpoint of UV and label it M. Then
draw TM, the median from 2T to side UV.
(b) Prove algebraically that the median TM is not perpendicular to UV. Explain.
Please helpppppp
Step-by-step explanation:
a) for the first part, you take your compass and stretch it more than halfway on to line UV. Place the fixed point at V and draw a curve. make sure you keep your compass the same size, put the fixed part of your compass on point U and draw a curve again. both curves should go both upward and downward. Now, your curves should meet at two points. use your straight edge to draw the line that meets at both points. I have drawn an example of what it should approximately look like. for the second part you are simply using your straight edge to draw a line from T down to the median M you previously found. I have drawn a second picture to show you.
b) now to check if they are perpendicular, we must find the slope of each line. I will not be able to do this accurately since I didn't use an exact method to find M, so you must follow my steps.
Step 1: find the slope of UV. To do so, we must take two points from the line. I will take points U and V because they are easiest to see. To find the slope, we can use the equation:
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
where m is the slope.
so, let's define our points.
Point V is (4,4), let's call this point one.
Point U is (14,6), let's call this point two.
So,
x1= 4
y1= 4
and
x2= 14
y2= 6
now, we can plug these into our slope equation.
[tex]m = \frac{6 - 4}{14 - 4} = \frac{2}{10} = \frac{1}{5} [/tex]
You must then use the points T and M in order to solve the second slope. Where T is (2,12). I will keep M as (x1, y1) for now.
The equation should then look like:
[tex]m = \frac{2 - y1}{12 - x1} [/tex]
now, in order for it to be perpendicular to our original slope, it must be the opposite reciprocal, which is the number flipped and made negative. The opposite reciprocal of 1/5 will be -5.
It should NOT be, as we have been told. So, we can state:
"I know that TM is not perpendicular to UV because the UV has a slope of 1/5 and TM has a slope of x, which is NOT the opposite reciprocal on 1/5."
Hope this helps! :)
