Step-by-step explanation:
Potential energy = mgh

Answer:
n = -21/11
Step-by-step explanation:
11(n - 1) + 35 = 3
Expand the brackets.
11n - 11 + 35 = 3
Add the terms -11 and 35.
11n + 24 = 3
Subtract 24 on both sides.
11n = 3 - 24
Subtract.
11n = -21
Divide 11 into both sides.
n = -21/11
Answer:
[tex]n = - \frac{21}{11} \\ [/tex]
Step-by-step explanation:
[tex]11(n - 1) + 35 = 3 \\ 11n - 11 + 35 = 3 \\ 11n + 24 = 3 \\ 11n = 3 - 24 \\ 11n = - 21 \\ \frac{11n}{11} = \frac{ - 21}{11} \\ n = - \frac{21}{11} [/tex]

Julio takes a multivitamin and a calcium vitamin every day. One at a time, he randomly pulled 8 cherry, 5 grape, and 7 orange gummy vitamins out of the multivitamin container and put them back each time. He also randomly pulled 11 berry, 3 lemon, and 6 pineapple gummy vitamins out of the calcium container and put them back each time.
Based on this information, what is the probability that Julio will select an orange
multivitamin and a lemon calcium vitamin the next time he takes his vitamins?
Answers
Answer: 21/400
Step-by-step explanation:
Multivitamin:
8 cherry, 5 grape, and 7 orange
Total fruits in Multivitamin container :
(8 + 5 + 7) = 20
P(orange) = Total required outcome / Total possible outcomes)
P(orange) = 7/20
Calcium vitamin :
11 berry, 3 lemon, and 6 pineapple
Total fruits in calcium vitamin container:
(11 + 3 + 6) = 20
Probability of picking a lemon:
P(lemon) = Total required outcome / Total possible outcomes)
P(lemon) = 3/20
Therefore, probability of picking an orange and a lemon equals:
P(orange) × p(lemon) = (7/20) × (3/20) = 21/400

Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry of this function: (WILL GIVE THE RIGHT ANSWER BRANLIEST)
h(x) = (x − 1)2 − 9.
Answers
Answer:
Vertex : (1, -9)
Axis of symmetry : x = 1
x-intercepts : (-2, 0), (4, 0)
y-intercept : (0, -8)
Step-by-step explanation:
Quadratic function to be graphed is,
h(x) = (x - 1)² - 9
By comparing this equation with the vertex form of the parabola,
f(x) = (x - h)² + k
here (h, k) is the vertex of the parabola.
Therefore, vertex of the parabola to be graphed will be (1, -9)
Since coefficient of highest degree term (x²) is positive, parabola will open upwards.
Axis of symmetry of the parabola,
x = 1
For x-intercepts,
(x - 1)² - 9 = 0
(x - 1)² = 9
(x - 1) = ±3
x = 1 ± 3
x = -2, 4
Points of x-intercepts will be (-2, 0), (4, 0).
For y-intercepts, (x = 0)
h(x) = (0 - 1)² - 9
= 1 - 9
= -8
So the point of y-intercept will be (0, -8).
Answer:
Vertex : (1, -9)
Axis of symmetry : x = 1
x-intercepts : (-2, 0), (4, 0)
y-intercept : (0, -8)

SR =3
Step-by-step explanation:
SR + RQ = SQ
2x+23 + x+21 = 14
Combine like terms
3x+44 = 14
Subtract 44 from each side
3x+44-44= 14-44
3x = -30
Divide each side by 3
3x/3 = -30/3
x = -10
SR = 2x+23 = 2(-10)+23 = -20+3 =3
Answer: 3
Step-by-step explanation:
We can start by making an equation.
Since we know the total length of SQ we can add SR + RQ to equal SQ.
[tex](2x+23)+(x+21)=14[/tex]
The parenthesizes are not necessary but they help for understanding the parts of the equation.
We will remove the parenthesizes and combine like terms.
[tex]3x+44=14\\[/tex]
Now subtract 44 from both sides to cancel it out from the side with x.
[tex]3x=-30[/tex]
Now divide by 3 to isolate x.
[tex]x=-10[/tex]
So x = -10.
Now we can plug in the value of x into SR.
[tex]2(-10)+23 = SR[/tex]
Solve
So SR = 3
Three pieces of ribbons measuring 0.5km, 1005cm and 1,800mm respectively are joined end to end form a single one. How long is the new ribbon? Find the cost of the single so formed at the rate of Rs.12 per meter?
Answers
Answer:
The new ribbon is 511.85 meter long.
The total cost Rs. 6142.2
Step-by-step explanation:
First of all we convert all lengths to the standard unit that is meter.
0.5 km =500 meter
1005 cm = 10.05 meter
1800 mm = 1.8 meter
total length in meters
500+10.05+1.8= 511.85
total cost at the rate of Rs. 12 per meter will be
511.85×12=6142.2
The length of the new ribbon is 511.85m.
The cost of the single ribbon formed is Rs. 6142.20.
What are different units of length? How are they related?Common units of length are Millimeter(mm), centimeter(cm), meter(m), and kilometer(km).
The S.I. unit of length is the meter.
All units relate to the meter in the following way:
1000mm = 1m ⇒ 1mm = 1/1000m ⇒ 1mm = 0.001m
100cm = 1m ⇒ 1cm = 1/100m ⇒ 1cm = 0.01m
1km = 1000m
How do we solve the given question?The lengths of three pieces of ribbon are given as 0.5km, 1005cm, and 1800mm.
We are asked to find the length of the ribbon formed by joining these 3 ribbons.
To find the total length, we need to add them, but to add we need lengths in equal units. So we convert the three lengths into the common unit meter.
0.5km = 0.5 * 1000 m = 500m (∵ 1km = 1000m)
1005cm = 1005 * 0.01m = 10.05m (∵ 1cm = 0.01m)
1800mm = 1800 * 0.001m = 1.8m (∵ 1mm = 0.001m)
∴ The length of the new ribbon = 500 + 10.05 + 1.8 m = 511.85m.
Cost of the ribbon = Rs. 12 per meter
∴ Cost of the single ribbon formed = Rs. 12 * 511.85 = Rs. 6142.20.

Andrew is trying to create a number puzzle for his younger sister to solve. He challenges his sister to find the mystery number. “When 4 is subtracted from half of a number the result is 5.” The equation to represent the mystery number is 1/2−4=5.
Andrew’s sister tries to guess the mystery number.
a. Her first guess is 30. Is she correct? Why or why not?
b. Her second guess is 2. Is she correct? Why or why not?
c. Her final guess is 4 1/ 2. Is she correct? Why or why not?
Answers
None of these guesses are correct.
Let's work this problem in reverse.
Try it this way.
1/2x-4=5
This is actually quite simple to solve.
Because half of x minus 4 will equal 5, we just need to add 4 and 5 to get half of our mystery number. 4+5=9. So, 9 is half of x. Add 9 to 9 to get our mystery number, which is 18.
30 is not correct because Half of 30 is 15, and 15-4 is 11, not 5.
2 is also not correct because half of 2 is one, and 1-4 is -3, not 5.
4 1/2 is not correct as well because half of 4 1/2 is 2 1/4, and 2 1/4-4 is -2 1/2, not 5.
Hope this helped!
None of her guesses are correct. “When 4 is subtracted from half of a number the result is 5.” The number should be 18.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
When 4 is subtracted from half of a number the result is 5.”
Let the number be x
x/2-4=5
We need to find the value of x
x/2=5+4
x/2=9
x=18
a. Her first guess is 30. Is she correct
No, the number should be 18 not 30 because half of 30 is 15 and when we subtract 4 from 15 we get 11
b. Her first guess is 2. Is she correct
No, the number should be 18 not 2 because half of 2 is 1 and when we subtract 4 from 1 we get -3.
Even 4 1/ 2 is not correct hence 18 is not correct.
