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.

a woman making $2500 per month has her salary reduced by 10% because of sluggish sales. one year later, after a dramatic improvement in sales, she is given a 20% raise over her reduced salary. find her salary after the raise. g
After the raise, the salary of woman becomes $2700.
Salary Reduction and RaiseThe answer was determined through simple arithmetic calculations.
First, the initial salary of $2500 was reduced by 10%, which is calculated as $2500 * 0.1 = $250.So the new salary after the reduction was $2500 - $250 = $2250.Next, a 20% raise was given over the reduced salary of $2250, which is calculated as $2250 * 0.2 = $450.Finally, the raise was added to the reduced salary, resulting in $2250 + $450 = $2700.So, the woman's salary after the raise is $2700.This method of calculation can be applied to any similar scenario where an initial salary is reduced by a certain percentage and then increased by another percentage. The formula used can be generalized as:
Final Salary = (Initial Salary - Initial Salary * Reduction Percentage) * (1 + Raise Percentage)
It's a simple and straightforward method that can be easily applied to find the final salary in similar cases.

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.

Sales of the smart phone continued to grow exponentially beyond 2011.
In 2010, approximately 39.99 million smartphones of this brand were sold worldwide.
In 2011, approximately 72.9 million smartphones of this brand were sold worldwide.
In which year did the number of smartphones the brand sold exceed 200 million?
Answer: This question can be solved using exponential growth formula:
N = N0 * e^(rt)
Where N is the number of smartphones, N0 is the initial number, r is the growth rate, t is the number of years and e is the base of the natural logarithm (approximately equal to 2.718).
First, we need to find the growth rate:
r = (ln(N/N0)) / t
Using the data from 2010 and 2011:
r = (ln(72.9/39.99)) / 1
Next, we can find the year when the number of smartphones sold exceed 200 million:
N = 200 million
N0 = 39.99 million
t = (ln(N/N0)) / r
t = (ln(200/39.99)) / r
To find the year, we need to add t to the initial year 2010.
The number of smartphones the brand sold exceeded 200 million in the year 2023.

To solve this problem using a Venn diagram, we need to start by drawing a rectangle to represent the group of 50 students, and then draw two overlapping circles to represent the subjects of Math and Science. Let's label the regions of the Venn diagram as follows:
M: Students who like MathS: Students who like ScienceMS: Students who like both Math and ScienceNeither: Students who like neither Math nor ScienceWe know that 20 students like only Math, 15 students like only Science, and the number of students who like both subjects is unknown. We also know that the number of students who like neither subject is double the number of students who like both subjects. Let's use this information to fill in the Venn diagram:
The number of students who like at least one subject is the sum of the students who like only Math, the students who like only Science, and the students who like both subjects: 20 + 15 + MS.The number of students who like neither subject is double the number of students who like both subjects: 2MS.We can set up an equation using this information:

Answer:
∠ A = 138° , ∠ C = 75°
Step-by-step explanation:
ABCD has parallel bases and is a trapezium
each lower base angle is supplementary to the upper base angle on the same side.
∠ A + 42° = 180° ( subtract 42° from both sides )
∠ A = 138°
∠ B + ∠ C = 180 , that is
12x - 3 + 9x - 6 = 180
21x - 9 = 180 ( add 9 to both sides )
21x = 189 ( divide both sides by 21 )
x = 9

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.
