Geo joins Fitness Plus Gym. He pays a membership fee of $25 to join. Geo pays $550 for the year. Write and solve an equation to find the amount he pays per month. Let a represent the amount he pays per month
Answer:
Geo pays $43.75 per month for the gym.
Step-by-step explanation:
Given that:
Membership fee = $25
Amount paid for year = $550
Let,
a be the amount he pays per month.
And there are 12 months in a year.
Total amount = Membership fee + 12 * Per month fee
550 = 25 + 12a
550 - 25 = 12a
525 = 12a
12a = 525
Dividing both sides by 12
[tex]\frac{12a}{12}=\frac{525}{12}\\a=43.75[/tex]
Hence,
Geo pays $43.75 per month for the gym.

Solve for x
Please help
Step-by-step explanation:
[tex] \frac{x}{x + x + 6} = \frac{9}{30} [/tex]
[tex] \frac{x}{2x + 6} = \frac{9}{30} [/tex]
30x = 9(2x+6)
30x = 18x+54
30x-18x = 54
12x = 54
x = 54/12
= 27/6

Susan ate 1/6 of a pumpkin pie. Joseph ate 3/4 of the same pumpkin pie. How much pie is left
Answer:
1/12 of the pumpkin pie is left.
Explanation:
To solve this you have to add 1/6 and 3/4, but in order for you to do that, you have to change each of the fraction so they have the same denominator. To do this you have to find out what number 6 and 4 can both go into, which is 12. So since you know that 6 times 2 is 12, you would multiply two to both the numerator and denominator, and get 2/12 as the result. Next, you have to the same thing to 3/4, except since 4 times 3 is 12, you would multiply 3 to both the numerator and denominator instead, so you should get 9/12. The final thing that you have to do in order to get your answer is add 2/12 and 9/12 which would be 11/12. Since you know that 11/12 is how much Susan and Joseph ate, the remaining 1/12 is how much of the pie is left.
I hope this helped you :D

Simplify: 18q2−45q+25/9q2−25.
Answer:
[tex]\frac{(6q-5)}{(3q+5)}[/tex]
Step-by-step explanation:
Given: [tex]\frac{18q^{2}-45q+25 }{9q^{2}-25 }[/tex]
Factorizing the numerator and the denominator, we have:
18[tex]q^{2}[/tex] - 45q + 25 = 18[tex]q^{2}[/tex] - 30q - 15q + 25
= (3q - 5)(6q - 5)
and
9[tex]q^{2}[/tex] - 25 = (3q - 5)(3q + 5)
So that,
[tex]\frac{18q^{2}-45q+25 }{9q^{2}-25 }[/tex] = [tex]\frac{(3q-5)(6q-5)}{(3q-5)(3q+5)}[/tex]
= [tex]\frac{(6q-5)}{(3q+5)}[/tex]
Therefore,
[tex]\frac{18q^{2}-45q+25 }{9q^{2}-25 }[/tex] = [tex]\frac{(6q-5)}{(3q+5)}[/tex]

Step-by-step explanation:
First, find the cost to cover one pair of shoes.
Cost to cover one pair of shoes = surface area of the shoe box × cost per square inch
= 2(LW + LH + HW) × 0.02
L = 14 in.
W = 8 in.
H = 4 in.
Plug in the values
Cost to cover one pair of shoes = 2(14*8 + 14*4 + 4*8) × 0.02
= 2(112 + 56 + 32) × 0.02
= 2(200) × 0.02
= 400 × 0.02 = 8
Cost to cover one pair of shoes = $8
Cost to cover 3 pairs of shoes = 3*8 = $24

OA. Equilateral
OB. Right
Oc. Acute
DD. Scalene
OE. sosceles
F Obtuse
Answer:
Scalene and Acute
Step-by-step explanation:
We know that,
A scalene triangle is a triangle whose none of the sides are equal in measure.
A triangle is acute if all of it's angle measure below 90 degree.
Here,
The sides of the given triangle are 12.1,11,10 and 12.1≠11≠10, due to which the triangle is scalene.
All the angles of the given triangle are 51,59,70 and 51,59,70<90, Hence, the given triangle is acute

The volume of a pyramid varies jointly with its height and the area of its base. A pyramid with a height of 16 feet and a base area of 78 square feet has a volume of 416 cubic feet. If a pyramid has a base area of 102 square feet and a volume of 238 cubic feet, find its height.
Answer:
7 ft
Step-by-step explanation:
base is b feet on each side
area of base is b² square feet
height is h feet
volume varies jointly with h and b²
V = kb²h
416 = k·78·16
k = ⅓
V = ⅓b²h
b² = 102
V = 238
h = 3V/b² = 7 ft

Answer:
A, C, D
Step-by-step explanation:
All three triangles can be proved congruent, so corresponding angles are congruent.
∆JKL ≅ ∆MNO ≅ ∆PQR
__
So, the statements that are true are ...
A) rigid motion can map ∆JKL to ∆MNO
C) ∆JKL can be proved congruent to ∆PQR
D) ∠N can be proved congruent to ∠Q
_____
About the other choices
B. When triangles are congruent, there is some rigid motion that maps one to the other. It is false to say there is none such.
E. ∠L has a measure of 65° (not 55°), as do the corresponding angles in the other triangles.
