The Temperature at 7PM
Step-by-step explanation:
You can buy 3 T-shirts for $24. Write a proportion that gives the cost c of buying 7 T-shirts. $$
Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
B. The school prom committee sold presale tickets for
$18 each. Couples that showed up on the day of the
dance has to pay $24 each. There were 334 tickets
that were sold and the committee made $7320. How
many students purchased tickets at the dance?
Answer:
218 students purchased tickets at the dance.
Step-by-step explanation:
Let,
x be the number of presale tickets
y be the number of tickets sold at the dance
According to given statement;
x+y=334 Eqn 1
18x+24y=7320 Eqn 2
Multiplying Eqn 1 by 18
18(x+y=334)
18x+18y=6012 Eqn 3
Subtracting Eqn 3 from Eqn 2
(18x+24y)-(18x+18y)=7320-6012
18x+24y-18x-18y=1308
6y=1308
[tex]\frac{6y}{6}=\frac{1308}{6}\\y=218[/tex]
Therefore,
218 students purchased tickets at the dance.

out of these numbers which of them differ by 46. 29,17,38,71,35,63,24
Answer:
71
Step-by-step explanation:
Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd
71
We do not need to look at all differences.
We need to find two numbers fairly far appart,
and not all look promising.
You could look at approximate differences,
or you could look at the last digit.
71-35 and 63-17 are the only promising differences,
because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,
and when you calculate the last digit you calculate
11-5=6 and 13-7=6.
71-35=36

Ten gallons of a 25% salt solution are to be obtained by mixing solutions that are 13% salt and 33% salt
respectively. How many gallons of each are needed?
Answer:
salt + salt = salt
0.13x +3.3-0.33x =2.5
-0.20x=-0.8
x= 4 gallons (amt of 13% solution to be mixed)
10-x= 6 gallons (amt of 33% solution to be mixed)

14. Mrs. Buchanan is planning marching routines for the school band. The band has 36 members. Band members can march in any number of rows as long as each row has the same number of members. The marching path, however, limits members to 6 per row.
Question:
Make a list of the different arrangements that Mrs. Buchanan could use.
Answer:
[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]
Step-by-step explanation:
Given
[tex]Members = 36[/tex]
[tex]Rows\ Limit = 6[/tex]
Represent the rows with x and the column, y.
This means that:
[tex]x * y = 36[/tex]
Make y the subject:
[tex]y = \frac{36}{x}[/tex]
The list is then generated as follows:
When x = 6.
[tex]y = \frac{36}{6} = 6[/tex]
[tex](x,y) = (6,6)[/tex]
When x = 5
[tex]y = \frac{36}{5} = 7.2[/tex]
This result can not be use because the result of the number of columns must be an integer
When x = 4
[tex]y = \frac{36}{4} = 9[/tex]
[tex](x,y) = (4,9)[/tex]
When x = 3
[tex]y = \frac{36}{3} = 12[/tex]
[tex](x,y) = (3,12)[/tex]
When x = 2
[tex]y = \frac{36}{2} = 18[/tex]
[tex](x,y) = (2,18)[/tex]
When x = 1
[tex]y = \frac{36}{1} = 36[/tex]
[tex](x,y) =(1,36)[/tex]
So, the possible list is:
[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]
John says the transformation rule (x, y) = (x + 4, y + 7)
can be used to describe the slide of the pre-image (4,5)
to the image (0, -2). What was his error?
Answer:
The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

You place a 16 foot ladder against a building. The angle that the ladder forms with
the ground is 60 degrees. How far from the base of the building is the bottom of
the ladder? round to the nearest foot.
Answer:The base of the ladder should be placed so that it is one foot away from the building for every four feet of hight to where the ladder rests against the building. This is known as the 4 to 1 rule.

3. What is the length of segment AB? Show or explain how you know.
Answers
I got answer 16.9
Step-by-step explanation:
1. Let's first look at triangle XYC. We know angle Y is 90 degrees because it has the symbol. and it is given that Angle X 45 degrees. Using the triangle interior angle theoreom, a triangle has 180 degrees so Angle C is 45 degrees. Know let find the sides, First we can deduce XY is 5 cm because of the triangle midsegment theorem XY is half of BC so since we know BC is 10 that means XY is 5. Then applying 45-45-90 triangle rules, XY=5, YC=5 and XC=[tex]5\sqrt{2}[/tex].
2.Now let look at the triangle XBC. Let find one missing angles. In the triangle . A angle bisector XC bisects XY and BC . Using that information Angle C of XYC = Angle C of XBC. So angle C=45 degrees. Knowing looking at the main triangle ABC Angle A=30, Angle C= 45+45=90 and Angle B=60 by interior triangle theorem. So going back to Angle X so angle x is 75 degrees due to interior triangle theorm. Also since Y=90 degrees it forms a linear pair to triangle AXY so Y=90 for AXY
Now let apply 30-60-90 triangle rules to AXY. XY =5, AY=[tex]5\sqrt{3}[/tex] and AX=10.
Finally. Apply 30-60-90 triangle rules to ABC. AC=[tex]5\sqrt{3}[/tex] +5 BC=10 and AB should turrn out to be 16.9.
This may not be right,but good luck:)
