what is the mean of the ages of the dance instructors?
IM GIVING BRAINLIEST‼️
Answers
Answer:
the answer to this is 25
Answer: 25
To find mean you first need to add up all the ages, which gives you 125. Then you divide that number by how many people. In this case it's 5, so divide 125 by 5 which gives you 25. And that's your answer.

solve the system of equations 2x+7y=-5 and-x-6y=10
Answers
Answer:
x=8 and y= -3
Step-by-step explanation:
2x + 7y= -5. eqn 1 ×6
-x -6y = 10. eqn 2 ×7
12x + 42y = -30
+
-7x - 42y = 70
= 5x= 40
x= 8
to find y
substitute x into eqn 2
-8-6y=10
-6y=10+8
-6y=18
therefore 6=-3

divide 90kg into the ration 2:3:7
Answers
the answer would have to be 465
Answer:
Weight of a pile of sand = 90 Kg
Ratio of weight of sand in three bags =
2 : 3 : 7
Let the weights be 2x kg, 3x kg and 7x kg respectively
A.T.Q.
=> 2x + 3x + 7x = 90
=> 12x = 90
=> x = 90/12
=> x = 7.5 Kg
___________________________
Weight of sand in small bag =
=> 2 × 7.5
=> 15 Kg ANS
Weight of sand in medium bag =
=> 3 × 7.5
=> 22.5 Kg ANS
Weight of sand in large bag =

Step-by-step explanation:
To simplify this we will need to use the distributive property
we can start with
6*4x=24x
then we can do
6*3=18
and since their is a negative sign in the middle that is what we do, so it will be

Danny reads for one half hour every day.
At the end of four weeks, how many hours has Danny read?
Answers
There are 7 days in a week.
1/2 hour x 7 days = 3 1/2 hours per week.
3 1/2 hours per week x 4 weeks = 14 hours
He read for a total of 14 hours
Answer:
14 hours
Step-by-step explanation:
half hour = 30 minutes
1 week = 7 days
30(minutes) x 7(days) = 210 minutes
210(minutes) x 4(weeks) = 840 minutes
Now we know how much time Danny has read (840 minutes), but we need to know what that is in hours.
840 minutes = how long Danny has read in minutes
60 minutes = hour
840(minutes) ÷ 60(minutes) = 14(hours)

Acute

Obtuse
Answers
Answer:
3) Obtuse
4) Right
Step-by-step explanation:
3)
11 + 13 > 25 It is a triangle
11² + 13² = 25²
121 + 169 = 625
290 ≠ 625
Since hypotenuse is larger, the triangle is obtuse
4)
21 + 28 > 35 It is a triangle
21² + 28² = 35²
441 + 784 = 1225
1225 = 1225
Since the hypotenuse is equal to the legs, it's a Right triangle
A heavy rope, 50 ft long, weighs 0.6 lb/ft and hangs over the edge of a building 120 ft high. Approximate the required work by a Riemann sum, then express the work as an integral and evaluate it.
Exercise (a)
How much work W is done in pulling the rope to the top of the building?
Exercise (b)
How much work W is done in pulling half the rope to the top of the building?
Answers
Answer:
Exercise (a)
The work done in pulling the rope to the top of the building is 750 lb·ft
Exercise (b)
The work done in pulling half the rope to the top of the building is 562.5 lb·ft
Step-by-step explanation:
Exercise (a)
The given parameters of the rope are;
The length of the rope = 50 ft.
The weight of the rope = 0.6 lb/ft.
The height of the building = 120 ft.
We have;
The work done in pulling a piece of the upper portion, ΔW₁ is given as follows;
ΔW₁ = 0.6Δx·x
The work done for the second half, ΔW₂, is given as follows;
ΔW₂ = 0.6Δx·x + 25×0.6 × 25 = 0.6Δx·x + 375
The total work done, W = W₁ + W₂ = 0.6Δx·x + 0.6Δx·x + 375
∴ We have;
W = [tex]2 \times \int\limits^{25}_0 {0.6 \cdot x} \, dx + 375= 2 \times \left[0.6 \cdot \dfrac{x^2}{2} \right]^{25}_0 + 375 = 750[/tex]
The work done in pulling the rope to the top of the building, W = 750 lb·ft
Exercise (b)
The work done in pulling half the rope is given by W₂ as follows;
[tex]W_2 = \int\limits^{25}_0 {0.6 \cdot x} \, dx + 375= \left[0.6 \cdot \dfrac{x^2}{2} \right]^{25}_0 + 375 = 562.5[/tex]
The work done in pulling half the rope, W₂ = 562.5 lb·ft

Playland Park charges $25 admission plus $2 per ride. Funland Park charges $35 admission plus $1 per ride. For what number of rides is the total cost the same at both parks? Does any body know the answer to this question?
Answers
Answer:
10 rides
Step-by-step explanation:
Make an equation.
25 + 2x = 35 + 1x
Subract 1x from the 2x to get 1.
New Equation: 25 + 1x = 35
Subtract 25 from 35 to get 10.
New Equation: 1x = 10
Divide 1 from both sides.
Answer: 10 rides

Kent is 12 4/5 years old. Lane is 1 1/6
Years Older than kent and jane
is 1 1/3 year older than lane
How old is jane?
Answers
Answer:
[tex]Jane = 15\frac{3}{10}[/tex]
Step-by-step explanation:
Given
[tex]Kent = 12\frac{4}{5}[/tex]
[tex]Lane = 1\frac{1}{6} + Kent[/tex]
[tex]Jane = 1\frac{1}{3} + Lane[/tex]
Required
Determine Jane's age
Substitute [tex]Kent = 12\frac{4}{5}[/tex] in [tex]Lane = 1\frac{1}{6} + Kent[/tex]
[tex]Lane = 1\frac{1}{6} + 12\frac{4}{5}[/tex]
[tex]Lane = \frac{7}{6} + \frac{64}{5}[/tex]
Take LCM
[tex]Lane = \frac{45+384}{30}[/tex]
[tex]Lane = \frac{419}{30}[/tex]
Substitute [tex]Lane = \frac{419}{30}[/tex] in [tex]Jane = 1\frac{1}{3} + Lane[/tex]
[tex]Jane = 1\frac{1}{3} + \frac{419}{30}[/tex]
[tex]Jane = \frac{4}{3} + \frac{419}{30}[/tex]
Take LCM
[tex]Jane = \frac{40+419}{30}[/tex]
[tex]Jane = \frac{459}{30}[/tex]
[tex]Jane = 15\frac{3}{10}[/tex]
