If the following ratios are proportional, what is the missing quantity? 10.2/3 ; 17/5; _____/11; 57.8/17
Answer:
37.4Step-by-step explanation:
Use one of ratios to find the missing quantity:
17/5 = x/11Cross-multiply:
5x = 17*11x = 17*11/5x = 37.4The scatterplot below shows the number of hours that some high school students spend on working and on video games.
A graph title Working and Video games has weekly working hours on the x-axis and weekly hours of video games on the y-axis. Points are grouped together and decrease.
Which statement about the scatterplot is true?
In general, the number of hours spent working does not affect the number of hours spent on video games.
In general, the amount of weekly time spent working is equal to the amount of weekly time spent on video games.
As the amount of time spent working increases, the amount of time spent on video games increases.
As the number of hours spent working increases, the amount of time spent on video games decreases.

For each of the 6 pairs of triangles below, determine if the triangles can be proved congruent. If yes, tell which of the patterns it fits (SSS, SAS, ASA, or AAS)
Answer:
a. is congruent by SSS
b. is congruent by AAS
c. is congruent by ASA
d. is congruent by SAS
Step-by-step explanation:
a. is SSS because all sides are marked
b. is AAS because the point where the two triangles meet are vertical angles and the one side of the triangle is marked congruent making AAS
c. is ASA because the angles are on segment FG and segment BC and there is a congruent line in between the two angles making ASA
d. is SAS because the triangles share the segment QS and when two triangles share a segment, that segment is congruent. the outside segment is congruent and then there is an angle and then the inside segment is congruent
Twice a number increased by seven is equal to five. Which of the following represents the equation and solution for this statement?
2 n + 7 = 5; n = -4.5
2 n = 7 + 5; n = 6
2 n + 7 = 5; n = -1
2( n + 7) = 5; n = -4.5
Hey there!
The answer to your question is the third option: 2n + 7 = 5; n = -1
"twice a number increased by 7" would represent 2n + 7, and if it's equal to 5, it would be 2n + 7 = 5. That rules out the last option, and the second option. Now, we have to solve for "n":
2n + 7 = 5 Step 1: Write the equation.
2n = -2 Step 2: Subtract 7 from both sides.
n = -1 Step 3: Divide both sides by 2.
Therefore, "n" is equal to -1, and the third option would be correct.
Hope it helps! Have a great day, and good luck on your assignment!

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)

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:)
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
Divide € 165 into the ratio 1:2:12
Answer:

Step-by-step explanation:
1 + 2 + 12 = 15
165 ÷ 15 = 11
1 × 11 = 11
2 × 11 = 22
12 × 11 = 132

Answer:
15/20 16/20 <
Step-by-step explanation:
First, make a common denominator for both, which is 20. So, 3/4 = 15/20. Then 4/5= 16/20. 15/20 < 16/20, so 3/4 < 4/5.

A student tried to solve the following equation but made a mistake.
Step 1: 4 – 8x = -28
Step 2: -8x = -24
Step 3: x = 3
What mistake did the student make?
9514 1404 393
Answer:
in Step 2, the student added 4 on the right and subtracted 4 on the left
Step-by-step explanation:
In Step 2, the student subtracted 4 on the left side of the equation, but incorrectly added 4 on the right. (The same operation needs to be performed on both sides of the equation.) The correct step 2 would be ...
-8x = -32 . . . . correct step 2
x = 4 . . . . . correct step 3
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.

Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she has $4.05 how many nickels and dimes does laura
Answer:
Number of dimes = 34
Number of nickels = 13
Step-by-step explanation:
Total number of coins = 47
Coins are in the form of nickels and dimes.
Value of a nickel = 5 cents
Value of a dime = 10 cents
Total value of coins = $4.05 or 405 cents
To find:
Number of nickels and dimes?
Solution:
Let number of nickels = [tex]x[/tex]
Money value of nickels = 5[tex]x[/tex]
Let number of dimes = [tex]y[/tex]
Money value of dimes = 10[tex]y[/tex]
Total value of coins = [tex]5x+10y[/tex]
This value is given as equal as 405.
As per question statement, the equations can be written as:
[tex]5x+10y = 405 ..... (1)\\x+ y = 47 ...... (2)[/tex]
Multiplying equation (2) with 5 and subtracting from equation (1):
[tex]10y - 5y = 405 - 235 \\\Rightarrow 5y = 170\\\Rightarrow y = 34[/tex]
Number of dimes = 34
Number of nickels = 47 - 34 = 13
