Step-by-step explanation:
What is Joey's total distance run on the first day?
Joey runs 5 laps around the track, which we can assume is 1 mile per lap. So, she runs 5 miles. Additionally, she runs 1.5 miles, so her total distance run on the first day is 5 + 1.5 = 6.5 miles.
What is Joey's total distance run on the second day?
Joey runs 3 laps around the track, which we can assume is 1 mile per lap. So, she runs 3 miles. Additionally, she runs 4 miles, so her total distance run on the second day is 3 + 4 = 7 miles.

Shalu cycles to her school at an average speed of 12 km/hr. It takes her 20 minutes to reach the school. If she wants to reach her schoo n 15 minutes, what should be her average speed?
Answer:
She should walk at a rate of 16 km/hr
Step-by-step explanation:
At a rate of 12 km/hr, she would have traveled 4 km in 20 minutes. This can be calculated by finding the ratio of 20 minutes to 1 hour which is 1/3. We then multiply this ratio by the rate to find the distance Shalu needs to walk to school.
We then need to find the necessary km/hr in order for Shalu to travel 4 km in 15 minutes. 15 minutes is a quarter of 1 hr. Therefore a rate of 4 km/15 minutes is equal to a rate of 16 km/hr. This means that the average speed Shalu would have to walk is 16 km/hr.

Lesley's fruit salad contains 40% grapes. Which figure represents 40%?
A. A hundred grid with five columns of ten squares shaded
B. A hundred grid with four columns of seven squares shaded
C. A hundred grid with three columns of ten squares shaded
D. A hundred grid with four columns of ten squares shaded
Answer:
The answer is D
Step-by-step explanation:
Percentages can be represented in Hundred Grid. It is a 10*10 grid that helps solves problems like yours.
In your case, it says 'Which figure represents 40% ?'
This means that you must shade 4 whole columns.
Because number 1, Each row or column contains 10 squares which can also represent 10%. And if you were to shade 2 rows or columns that would mean it is 20%.
So to sum it up:4 whole columns = 40% out of 100
So a hundred grid with 4 columns of ten square shaded should be your answer.

Two types of memberships are available for a water park
an unlimited use membership for $70 per month, or
a monthly $10 fee plus $5. 00 per visit
enter an equation that can be used to find the number of visits (v) per month needed for the two membership types to cost the same amount
Answer:
10+5v=70
Step-by-step explanation:
this is because you need to consider the outright monthly cost of $10 first. then you don't know how many visits you'll need so you have to fill in v and multiply it by the cost per visit. and it must equal 70 so that it is equal to the other membership.
The equation 70 = 10 + 5v is used to determine the number of visits per month needed for two membership types to cost the same. Solving the equation would provide that 12 visits a month will make both memberships cost the same.
Explanation:The subject of this question is Mathematics, and it is related to the topic of linear equations. Given the problem, we know that there are two types of membership options:
An unlimited use membership for $70 per month. This can be represented as: Y = 70, A membership that costs a monthly $10 fee plus $5 per visit. This can be represented as: Y = 10 + 5v.Here, Y represents the total cost of the membership each month and v represents the number of visits to the water park per month. You can set these two equations equal to each other in order to find the number of visits (v) needed for the two membership types to cost the same amount:
70 = 10 + 5v
You solve the equation for v to get: v = (70 - 10) / 5 = 12
Therefore, it would take 12 visits per month for both memberships to cost the same.

Find the HCF :
2x^3+x^2-3x and x^3-x
Answer: To find the highest common factor (HCF) of two polynomials, we can use the Euclidean algorithm for polynomials. The Euclidean algorithm involves dividing the larger polynomial by the smaller polynomial and continuing the division process until the remainder is zero. The last non-zero remainder is the HCF of the two polynomials.
In this case, we have:
2x^3 + x^2 - 3x = (2x^3 - x^3) + x^2 - 3x
= x^3 + x^2 - 3x
Now, we divide x^3 + x^2 - 3x by x^3 - x
x^3 + x^2 - 3x = x^3 - x * (1 + x - 3)
= x^3 - x * (x^2 - 2x + 3)
We cannot simplify this expression further, so the HCF of 2x^3 + x^2 - 3x and x^3 - x is x^3 - x.

A Six Sigma program has how many defects per million? 27006 times the standard deviation3410003.4
By standard deviation, 3.4 defects per million that a six sigma program has. Whereas the remaining ones are not appropriate in this context.
What does standard deviation mean ?
The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean.
Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.
Describe standard deviation using an example?
The dispersion of the data around the mean value is measured by the standard deviation. It might be helpful when comparing data sets that may have the same mean but a different range.
The means of the two numbers 15, 15, 15, 14, 16, and 2, 7, 14, 22, 30 are the same, for instance. The second is, however, obviously more dispersed.

find n
(2²n)4x(2^n)2=2^16-1
The value of "n" is approximately 2.6666667.
What is exponent ?Exponent is a mathematical operation that represents repeated multiplication of the same number.
We can start by simplifying the left side of the equation:
(2^(2n))^4 * (2^n)^2 = 2^16 - 1
Using the exponent rules:
a^m * a^n = a^(m + n)
We can simplify the left side of the equation further:
2^(4n + 2n) = 2^16 - 1
Combining the exponents:
2^(6n) = 2^16 - 1
Now we can use the fact that if a^m = a^n, then m = n to solve for "n":
6n = 16
Dividing both sides by 6:
n = 16/6 = 8/3
Therefore, The value of "n" is approximately 2.6666667.

3. A bumblebee of mass 0.015 kg is traveling at 21.0 m/sec when it collides with a windshield. How much kinetic energy does the bee have as it hits the windshield? Show work thanks for the help
Answer:
Step-by-step explanation:
KE = (1/2) * m * v^2
where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
We are given the mass of the bumblebee as 0.015 kg and its velocity as 21.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:
KE = (1/2) * m * v^2
= (1/2) * 0.015 kg * (21.0 m/sec)^2
= (1/2) * 0.015 kg * 441.0 m^2/sec^2
= 2.92625 J
Therefore, the bumblebee has 2.92625 Joules of kinetic energy as it hits the windshield.
Answer:
The kinetic energy of the bumblebee as it hits the windshield is given by the equation KE = 0.5 x 0.015 kg x (21.0 m/s) squared. This gives us a total of 945 J of kinetic energy.

According to the question, the depth of the water is 11 feet.
What is the depth ?The depth of something refers to how deep or far down it goes. It can refer to physical measurements such as the depth of a lake or ocean or the depth of a hole, or to metaphorical measurements such as the depth of knowledge or the depth of emotions. In terms of physical measurements, depth is usually referred to in terms of length or distance.
Let x be the depth of the water
The reed is 11 feet tall (10 feet in the water + 1 foot above the water)
The circumference of the pool is 10π feet
The volume of water in the pool = (circumference x depth) = 10πx
The volume of the reed = (area of base x height) = π(5²) x 11 = 275π
The total volume of the pool and reed = 10πx + 275π
10πx + 275π = 10π(11)
10πx = 110π

Round your answer to the nearest tenths place if needed.
For rectangle ABCD, the value of x is 6.44 inches
Consider the following diagram.
From this figure we can observe that the dimansions of the rectangle: length is given by expression (7x + 1) and width is given by expression 'x'
We know that tha formula for the perimeter of the rectangle,
P = 2 × (length + width)
Here, the perimeter of rectangle ABCD is 105 inches.
Using above formula of perimeter we get an expression,
P = 2 × ((7x + 1)+ x)
