The ratio of the number of boys to the number of girls in a dance club is 5 : 6. After 6 more boys join the club, the ratio became 13 : 12. How many people were in the club at the start?
Answers
44
Step-by-step explanation:
let boys be x and girls be y
x/y=5/6
x=5y/6....(1)
if 6 boys join the club that will be x+6
Therefore:
(x+6)/y=13/12
13y=12x+72
13y-12x=72
Recall x=5y/6
Therefore:
13y-12(5y/6)=72
13y-(2*5y)=72
13y-10y=72
3y=72
y=24 people
Therefore:
x=(5*24)/6
x=20 people
Therefore people in the club before are 20+24=44

Timothy has some coins in a jar. He has 6 pennies,8 nickels,10 dimes, and four quarters. What is the ratio of the number of nickels to the number of dimes
Answers
Answer:
8:10
Step-by-step explanation:
If Timothy has some coins in a jar. He has 6 pennies,8 nickels,10 dimes, and four quarters. Then 4:5 is the ratio of the number of nickels to the number of dimes
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
Timothy has some coins in a jar.
The number of Pennies = 6
The number of Nickels = 8
The number of dimes =10
The number of quarters =4
We need to find the ratio of the number of nickels to the number of dimes
8/10
4/5
Hence 4:5 is the ratio of the number of nickels to the number of dimes

6 boxes of 3-inch incense sticks for $22.75 is a better buy than 8 boxes for $30 and 10 boxes for $38.00
True
False
Answers
Answer:
Step-by-step explanation:
22.75/6 boxes is $3.79 per box
30/8 boxes is $3.75 a box
38/10 boxes is $3.80 a box
68/18=3.70 a box if you combine the last two.
So no, the 6 boxes at $3.79 a box is not a better buy.

There is a elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, what is the Potential Energy that the wether vane has?
Answers
Answer:
Potential Energy = 8550 Joules
Step-by-step explanation:
The potential energy of the body is the energy possessed by it due to its position therefore:
Potential energy = mgh
m = mass of the body measured in kg
g= acceleration due to gravity
h= height or distance measured in meters
But in the question asked we are not given mass but weight so
w= mg measured in newtons
We have
w= 190 N
h= 45m
PE= mgh
PE = w h= 190 * 45 = 8550 J
The unit of energy is Joule.

Answer:
42 degrees
Step-by-step explanation:
Answer:
x=42°
Step-by-step explanation:
In any triangle, when all three angles are added together, their sum will always be 180°:
∠1+∠2+∠3=180
Insert any known values:
[tex]29+109+x=180[/tex]
Simplify the addition:
[tex]138+x=180[/tex]
Use inverse operations to find angle three. Subtract 138 from both sides:
[tex]138-138+x=180-138\\\\x=42[/tex]
Therefore, the unknown angle is 42°.

In the figure shown, what additional information is needed to show that △ABC≅△DEF by SSS?
Enter your answers in alphabetical order.
Answers
Answer:
Step-by-step explanation:
They're asking for what other information is needed.
We were given triangle ABC is congruent to triangle DEF. We know for certain line AB and line DC are congruent to each other as well as lines BC and EF.
The additional information we need to know is if line AC is congruent to line DF to absolutely be sure.
Remember SSS by definition is: Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other. If all three sides in one triangle are the same length as the corresponding sides in the other, then the triangles are congruent.
SSS congruence of triangles is proved when all three sides of considered two triangles are congruent(that is, of equal measures).
Thus, the needed answer is:
Line segment DF is congruent to line segment AC
or [tex]\overline{DF} \cong \overline{AC}[/tex]
What is SSS congruence of triangles?If two considered triangles have corresponding side pairs congruent(for all three sides), then both the triangles are congruent. This proof of congruence is triangle is done by SSS congruence of triangles (Side Side Side congruence)
Since it is given that the sides CB and FE are congruent,
and since it is given that sides AB and DE are congruent too,
thus, for SSS congruence of both considered triangles, we need the third side pair of the given triangles to be congruent too.
Thus, we need the line segment DF congruent to the line segment AC.
We can write it symbolically as:
[tex]\overline{DF} \cong \overline{AC}[/tex] (remember that order doesn't matter here. You could've written [tex]\overline{AC} \cong \overline{DF}[/tex] too.)

In the diagram below, line segment AB has endpoints at A(-2,-6) and B (3,-1). Give the coordinates of line segment A'B' after a counterclockwise rotation of 90° about the origin.
Answers
Answer:
A’ (6,-2)
B’ (1,3)
Step-by-step explanation:
Here, we want to give the coordinates after a counterclockwise rotation of 90 degrees
Given a point with coordinates (x,y)
A counterclockwise rotation at 90 degrees to the origin will yield the coordinates (-y,x)
So A (-2,-6) will be A’ (6,-2) while B (3,-1) will be B’ (1,3)
