The amount of jumping packs in 1 minute is 21
How to determine the amount of jumping packs in 1 minute?From the question, the given parameters are:
Number of jumping packs in a row = 84 packs
Number of minutes = 4 minutes
The amount of jumping packs in 1 minute is the quotient of the number of jumping packs in a row and the number of minutes
This is represented as
Jumping packs in 1 minute = Number of jumping packs in a row /Number of minutes
Substitute the known values in the above equation
Jumping packs in 1 minute = 84/4
Evaluate
Jumping packs in 1 minute = 21
Hence, the jumping packs in 1 minute is 21

The record holder makes 21 jumping jacks in 1 minute which is the ratio of the number of jumping jacks performed in a row to the total number of minutes.
What is the ratio?A ratio is a relationship between two amounts that is represented by the division of one by the other.
The ratio of the total number of jumping jacks performed in a row to the total number of minutes determines how many jumping jacks should be performed in a minute.
No. of jumping packs in a row = 84 packs
No. of minutes = 4 minutes
So jumping packs in 1 minute = 84/4
Apply the division operation to get
Jumping packs in 1 minute = 21
Therefore, 21 jumping jacks should be performed in 1 minute.

Use four rectangles to estimate the area between the graph of the function f(x) = V3x + 5 and the x-axis on the interval[0, 4] using the left endpoints of the subintervals as the sample points. Round any intermediate calculations, if needed, to noless than six decimal places, and round your final answer to three decimal places.
Answer:
12.123
Step-by-step explanation:
You want the area under the curve f(x) = √(3x+5) on the interval [0, 4] estimated using the left sum and four subintervals.
Riemann sumWhen the interval [0, 4] is divided into four equal parts, each has unit width. That means the area of the rectangle defined by the curve and the interval width will be equal to the value of the curve at the left end of the interval.
The area we want is the sum ...
f(0) +f(1) +f(2) +f(3)
As the attachment shows, that sum is ...
area ≈ 12.123 . . . square units
__
Additional comment
The table values in the attachment are rounded to 7 decimal places. Trailing zeros are not shown. Actual values used have 12 significant digits, as the total shows.
Such a sum is called a Riemann sum, named for a German mathematician. Four such sums are commonly used, and further refinements are possible. Those are the left sum (as here), the right sum, the midpoint sum, and a sum using a trapezoidal approximation of the rectangle area.
For left, right, and midpoint sums, n function values are required for n subintervals. When the trapezoidal approximation is used, n+1 function values are required.

please help i need to get my grade up
Answer:
See below
Step-by-step explanation:
1. Multiply m to get, m(s + z)/2 => (ms + mz)/2
2. Mutiply by 2 by both sides
2B = MS + MZ
3. Divide By M
2B = M(S+Z)
2B/M = S+Z
4. Minus Z

Given:
Angle A = 120 degrees
Side opposite angle C = 150 meters
Side opposite angle B = 275 meters
Find:
Angle B
Solution:
Since we have two sides given and an included angle, we can use cosine law.
Let's look for the length of the side opposite Angle A first.
[tex]a^2=b^2+c^2-2bc\cos A[/tex]where a = length of the side opposite Angle A or side BC
b = side opposite Angle B or Side AC
c = side opposite Angle C or Side AB
A = Angle A
Since we already have the data above, let's plug it in to the formula we have.
[tex]a^2=275^2+150^2-2(275)(150)\cos 120[/tex]Then, solve a.
[tex]\begin{gathered} a^2=75,625+22,500-82,500(-0.5) \\ a^2=98,125+41,250 \\ a^2=139,375 \\ \sqrt[]{a^2}=\sqrt[]{139,375} \\ a\approx373.3296\approx373.33 \end{gathered}[/tex]Hence, the length of side opposite a or Side BC is approximately 373.33 meters.
Now, to solve for Angle B, we can use the sine law.
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}[/tex]Let's plug in the value of Angle A, side BC or a, and side AC or b to the formula.
[tex]\frac{\sin120}{373.3296}=\frac{\sin B}{275}[/tex]Then, solve for Angle B.
[tex]\begin{gathered} \sin B=\frac{275\sin 120}{373.3296} \\ \sin B=0.6379268552 \\ B=\sin ^{-1}0.6379268552 \\ B\approx39.64 \end{gathered}[/tex]Therefore, the bearing of ship C from ship B is approximately 40 degrees. (rounded off to the nearest degree)
hello i have a upcoming test and want to know how to solve this
Expression given:
[tex]g>1[/tex]To know how to graph the given expression, it is easier if we determine what it means in words. In this case, this expression means all the values above one (without including one).
We know that one is not included as it has the sing ">", if the value were included, then it would have the sing "≥" or "≤".
This is important because when you are graphing, a discontinuous line is drawn for values not included, and a continuous one for included values.
Now, we would have to evaluate if it is the independent variable (generally called x), or the dependent variable (generally called y).
Assuming that g is the dependent variable, then the graph would be like this:
However, if the variable was de independent variable, then it would look like this:
We have to note that both graphs go from 1 to bigger values.
Bob's Golf Palace had a set of 10 golf clubs that were marked on sale for $840. This was a discount of 10% off the original selling price.Step 2 of 4: If the golf clubs cost Bob's Golf Palace $390, what was their profit? Follow the problem-solving process and round youranswer to the nearest cent, if necessary.
Consider that the Bob's Golf Palace bought the set of golf clubs by $390.
Moreover, take into account that the golf clubs were markes on sale for $840.
The profit is only the difference between the marked on sale and the money Bob's Golf Palace payed:
$840 - $390 = $450
Hence, the profit was $450

For the function f(x), = 10 (√x + 9), find f-¹(x).
The inverse of the function f(x) = 10 (√x + 9) is f⁻¹(x) = (x - 90)² / 100
Given,
The function, f(x) = 10 (√x + 9)
We have to find the inverse of the function, f⁻¹(x)
Here,
f(x) = 10 (√x + 9)
f(x) = 10√x + 90
Replace f(x) with y.
y = 10√x + 90
Swap x with y;
x = 10√y + 90
Solve for y
That is,
x = 10√y + 90
x - 90 = 10√y
(x - 90) / 10 = √y
Square both sides
((x - 90) / 10)² = √y²
(x - 90)² / 100 = y
Replace y with f⁻¹(x)
That is,
f⁻¹(x) = (x - 90)² / 100
Therefore,
The inverse for the function f(x) = 10 (√x + 9) is f⁻¹(x) = (x - 90)² / 100

A flower garden is shaped like a circle. Its diameter is . A ring-shaped path goes around the garden. The width of the path is .The gardener is going to cover the path with sand. If one bag of sand can cover , how many bags of sand does the gardener need? Note that sand comes only by the bag, so the number of bags must be a whole number. (Use the value for .)
The number sand bags required are 84 approximately.
Given, we have:
Diameter of garden = 38 yd
Width of path = 5 yd
Diameter of garden with path = 38 + 2 x 5 = 48 yd
We need to find area of path.
Area of path = Area of garden with path - area of garden
Area of path = π × 48²/4 - π × 38²/4
Area of path = 7234.56/4 - 4534.16/4
Area of path = 1808.64 - 1133.54
Area of path = 675.1 yd²
Area covered by one sand bag = 8 yd²
Number of sand bags required = Area of path/Area covered by one sand bag
=675.1/8
= 84.38 ≈ 84
Number of sand bags needed = 84

From a group of 6 people, you randomly select 5 of them.
What is the probability that they are the 5 oldest people in the group?
Give your answer as a fraction
The probability that they are the 5 oldest people in the group is 1/6.
Given that we have a group of 6 people, and we randomly select 5 of them.
We need to find the probability that they are the 5 oldest people in the group.
The total number of ways to select 5 people from a group of 6 people is given by 6C5 which is equal to 6.
This means that there are only 6 possible outcomes when we randomly select 5 people from a group of 6 people.
We know that the 5 oldest people in the group can be selected only in one way.
So, the number of favorable outcomes is 1.
Hence, the probability of selecting the 5 oldest people from the group when 5 people are randomly selected is: Probability = favorable outcomes/total outcomes Probability = 1/6
Therefore, the probability that they are the 5 oldest people in the group is 1/6.
