There are 7 girls and 10 boys taking gymnastics lessons. Write the ratio that compares the number of girls taking gymnastics lessons to the total number of students taking gymnastics lessons
Answer:
7:17
Step-by-step explanation:
There are 7 girls and 10 boys taking gymnastics lessons. Write the ratio that compares the number of girls taking gymnastics lessons to the total number of students taking gymnastics lessons
Total number of students taking gymnastics classes = 7 girls + 10 boys = 17 students
Hence:
the ratio that compares the number of girls taking gymnastics lessons to the total number of students taking gymnastics lessons
= 7 : 17

Step-by-step explanation:
When invested at an annual interest rate of 4.7%, an account earned $1,290.33 of simple
interest in 3 years. How much money was originally invested? If necessary, round to the
nearest cent.
O $82,361.49
O $9,151.28
O $20.22
O $91,512.77
Answer:
The answer is 82,361.49
Step-by-step explanation:
after simplifying the equation, the problem is 1290.33 divided by .27 times 3 - the quotient is 82,362.49 (in simplified form)
The amount of money that he originally invested will be $9,151.28. Then the correct option is B.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
I = (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
When contributed at a yearly loan fee of 4.7%, a record acquired $1,290.33 of straightforward interest in 3 years.
Then the amount of money that he originally invested will be given as,
1290.33 = (P x 4.7 x 3)/100
Simplify the equation, then we have
1290.33 = (P x 4.7 x 3)/100
129033 = 14.1 x P
P = 129033 / 14.1
P = $9,151.28
The amount of money that he originally invested will be $9,151.28. Then the correct option is B.

If m<2= 123, m<12=38 and m<18=100, find the measure of each missing angle.
Answer:
see below
Step-by-step explanation:
a) ∠1 = 180 - 123 = 57°
b) ∠3 = 100° (congruent to ∠18)
c) ∠4 = 180 - 100 = 80°
d) ∠5 = 123° (opposite to ∠2)
e) ∠6 = 57° (opposite to ∠1)
f) ∠7 = 38° (alternate angle to ∠12)
g) ∠8 = 180 - ∠7 - ∠9 = 180 - 38 - 100 = 42°
h) ∠9 = 100° (congruent to ∠18)
i) ∠10 = 57° (congruent to ∠1)
j) ∠11 = 180 - ∠10 - ∠12 = 180 - 57 - 38 = 85°

Which is a needed step to prove that △ABF≅△EDG?
∠BCD≅∠BCD
△CFG is isosceles.
line GF≅line GF
∠BCG≅∠DCF
Answer:
ΔCFG is an isosceles triangle.
Step-by-step explanation:
From the picture attached,
From ΔABF and ΔEDG,
Conditions for ΔABF and ΔEDG by SSS property of congruence,
1). AB ≅ DE [Given]
2). (BC + CF) = (DF + CG)
CF = CG [Given → BC = DF]
3). FA ≅ EG
(AG + GF) ≅ (EF + GF)
AG ≅ EF
Since, two sides of ΔCFG are equal in measure
ΔCFG is an isosceles triangle.
This can be determined by property of congruency. Hence, [tex]\bold{2^{nd}}[/tex]option i.e. ΔCFG is an isosceles triangle is most appropriate.
Given :
From figure ΔABF and ΔEDG are congruence by SSS property.
Proof:
From ΔABF and ΔEDG in figure,
Conditions for ΔABF and ΔEDG by SSS property of congruence,
1). AB ≅ DE [Given]
(BC + CF) = (DC + CG)

Below are the daily rental costs for ski equipment at Benton Mountain Ski Resort. Robert rents one set of skis, two sets of poles, and two pairs of boots. The sales tax for the rental was $7.69. He paid with a $100 bill. SKI RENTALS Item Price Skis $25.00 Poles $7.95 Boots $14.50 How much change should Robert receive from the $100 bill? (Use the circle to select the correct answer below.)
Answer:
$22.41
Step-by-step explanation:
In order to calculate the amount of change that Robert should receive we need to add the cost of each item including the sales tax and then subtract that total from the $100 bill that Robert paid with. Which would be the following...
25 + 7.95 + 7.95 + 14.50 + 14.50 + 7.69 = 77.59
100 - 77.59 = 22.41
Finally, we can see that the total bill was $77.59 which means that Robert should receive $22.41 in change.
Lucy cuts 4 squares with side length x in. From the corners of a 6 in. By 9 in. Cardboard rectangle. She folds the remaining cardboard to make a tray that is x in. High. Write and simplify a function for the volume V of the tray in terms of x.
Answer:
4x³ - 30x² + 54x
Step-by-step explanation:
Length of the rectangular cardboard = 9 inches
Width of the rectangular cardboard = 6 inches
if the square of sides x inches is cut from each corner of the rectangular cardboard and folded to make a tray, then we have
Length of the tray = length of cardboard - 2(side of square )
= 9 - 2x
Width of the tray = width of cardboard - 2( side of square)
= 6 - 2x
height of tray = sides of square
= x
volume of tray = Length × width × height
= (9 - 2x) (6 - 2x) (x)
Open the parenthesis
= (54 - 18x - 12x + 4x²)(x)
= 54x - 18x² - 12x² + 4x³
= 54x - 30x² +4x³
Re-arrange
4x³ - 30x² + 54x
Volume, V of the tray in terms of x = 4x³ - 30x² + 54x
Answer:
4x^3-30x^2+54x

I thinks its 180 degrees conter clockwise
so one square thing is 90 degrees
and it goes 2 times
u welcome and good luck :)
Answer:
The answer is rotation 180 degrees counterclockwise about the origin.
Step-by-step explanation:
The first choice.
Looking at the other choices when u do a reflection across the y-axis then 8 units up point b doesn’t match up.
Second choice.
When you do a reflection across the x-axis you would have to do 10 units to the left not 4.
Third choice.
If u just do a rotation 90 degrees the triangle wouldn’t be in the right quadrant.
Therefore the choice is 4 the last one

A company has determined that 2 out of every 5255 bolts that it ordered is defective. What is the probability that that a worker will pick a bolt that is not defective? Enter your answer as a reduced fraction using / for the fraction bar. Do not use any spaces in your answer.
Answer:
5253 out of 5255 times.
[tex] \frac{5253}{5255} [/tex]
Step-by-step explanation:
Being that the we are determining the probobility of it not bein defecteve, then we simply count the bolts not defective rather then defective ones. We can do this simply by subtracting the defective bolts from 1, or total bolts recieved.
[tex]1 - \frac{2}{5255} [/tex]

The sum of all the angles of a triangle is 180 degrees.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is the sum of the measures of the interior angles of a triangle
As discussed above, the sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
Therefore, the sum of all the angles of a triangle is 180 degrees.
