Suppose you got these results from a survey that was taken to determine the percentage of people in a nearby city who visited a food pantry last month.
Calculate the percentage of people who visited the food pantry last month. Be sure to show your work.
15% of the people in the city visited the food pantry last month.
What is the percentage?
A percentage is a way of expressing a number as a fraction of 100. It is a ratio that compares a number to 100, and it is often denoted using the % symbol. For example, if there are 25 blue marbles in a jar of 100 marbles, we can say that 25% of the marbles are blue. This means that 25 out of every 100 marbles are blue.
To calculate the percentage of people who visited the food pantry last month, we can use the following formula:
Percentage = (Part / Whole) x 100%
where "Part" is the number of people who visited the food pantry last month, and "Whole" is the total number of people in the city.
Plugging in the given values, we get:
Percentage = (150 / 1,000) x 100%
Percentage = 0.15 x 100%
Percentage = 15%
Therefore, 15% of the people in the city visited the food pantry last month.

You choose to invest $600 a year in a 401k which invests in an international stock mutual fund. Assuming an annual rate of turn of 9 percent, how much will this fund worth if retiring in 40 years?
By using the future value of a series formula, you can calculate the future value of your investment. In this case, if you invest $600 annually in a 401k mutual fund with a 9% annual return, you will have approximately $132,204.02 after 40 years.
Explanation:To solve this problem, we can use the future value of a series formula (also known as an annuity), which is common in business finance. The formula is:
FV = P * [((1 + r)^n - 1) / r]
Where:
FV is the future value of the money you have invested.
P is the annual investment (in this case, $600).
r is the annual rate of return (which is 9% or 0.09 as a decimal).
n is the number of years the money is invested (which is 40 in this scenario).
Applying these numbers to the formula we get:
FV = 600 * [((1 + 0.09)^40 - 1) / 0.09]
After performing the calculations, the future value (which is the amount of money you'll have at the end of 40 years) comes out to be approximately $132,204.02. Thus, if you invest $600 annually in a 401k which invests in an international stock mutual fund with a 9% annual rate of return, you will have $132,204.02 in the fund when retiring in 40 years.

What is the answer to 1/5x = 3/10?
Answer:
To solve for x, we can cross-multiply:
1/5x = 3/10
10(1/5x) = 10(3/10)
2x = 3
x = 3/2
Therefore, the solution is x = 3/2.
Answer:
To solve the equation 1/5x = 3/10 for x, we need to isolate x on one side of the equation.
First, we can simplify the equation by multiplying both sides by the reciprocal of 1/5, which is 5/1 or simply 5:
(1/5)x = 3/10
5(1/5)x = 5(3/10)
x = 3/2
Therefore, the solution to the equation 1/5x = 3/10 is x = 3/2 or 1.5.

Determine showing all calculations which supermarket will be the best value for money.
Answer:
To determine which supermarket offers the best value for money, we need to compare the cost per kilogram (kg) of potatoes from both supermarkets.
For Supermarket A:
4.5 kg cost R20, so 1 kg costs R20/4.5 kg = R4.44 per kg (excluding VAT)
For Supermarket B:
1.8 kg cost R8, so 1 kg costs R8/1.8 kg = R4.44 per kg (excluding VAT)
As both supermarkets offer potatoes at the same cost per kg, they are equal in terms of value for money. Therefore, Betty and Valencia can choose either supermarket to purchase their potatoes for the mini tuck shop.

the scale factor between 0 and 1 ____ the size of an object, or makes it ___. A scale factor of 1 ______ the size of an object; that is, the size is ____. A scale factor greater than 1 ______ an object, or make it ___.
An object's size in real life and its size on a map or a blueprint are compared using a scale factor, which is a mathematical concept. The scale factor may exceed, fall short of, or be equal to 1.
What is scale factor and how is it calculated?The size of the object is decreased and becomes smaller if the scale factor is between 0 and 1. This is so because the scale factor only approximates the object's true size. The size of the thing on the map will be half that of the real object, for instance, if the scale factor is 0.5.
When the scale factor is 1, the object's size is said to remain constant. As a result, the map or blueprint is created using the same dimensions.
In other words, the map or blueprint is created at the exact same scale as the final product.
The size of the thing is enlarged and made larger if the scale factor is greater than 1. This is so because the scale factor is a multiple of the object's actual size. The size of an object on a map will appear twice as large as it is in reality, for instance, if the scale factor is 2.
In general, it's crucial to comprehend scale variables in order to appropriately depict an object's size on maps, blueprints, and other scaled representations.

Given that arc CA measures 78 degrees and arc DB measures 32 degrees, find the measurement of angle AXC.
Angle AXC is congruent to both angle CAX (78 degrees) and angle CDX (102 degrees), its measurement is also 102 degrees.
To find the measurement of angle AXC, we need to consider that it is an inscribed angle subtended by the same arc CX as arc CA and arc DB.
Inscribed angles that subtend the same arc are congruent. Therefore, we can conclude that angle AXC is congruent to both angle CAX and angle CDX.
Since angle CAX and angle CDX are supplementary angles (they add up to 180 degrees) and we know the measurement of angle CAX, we can find the measurement of angle CDX.
angle CAX + angle CDX = 180 degrees
78 degrees + angle CDX = 180 degrees
angle CDX = 180 degrees - 78 degrees
angle CDX = 102 degrees
Since angle AXC is congruent to both angle CAX (78 degrees) and angle CDX (102 degrees), its measurement is also 102 degrees.

Let the weight of P coffee in 800g of X be 3x, then the weight of Q coffee in 800g of X is 13x.
The total weight of X is 800g, so we have:
3x + 13x = 800
16x = 800
x = 50
Therefore, the weight of P coffee in 800g of X is:
3x = 3(50) = 150g
And the weight of Q coffee in 800g of X is:
13x = 13(50) = 650g
(b) To find the weights of type P coffee and type R coffee in 800g of Y, we can use the ratio of the three types of coffee in the blend, which is 1:7:12 by weight.
Let the weight of P coffee in 800g of Y be x, then the weight of Q coffee in 800g of Y is 7x and the weight of R coffee in 800g of Y is 12x.
The total weight of Y is 800g, so we have:
x + 7x + 12x = 800
20x = 800
x = 40
Therefore, the weight of P coffee in 800g of Y is:
x = 40g
And the weight of R coffee in 800g of Y is:
12x = 12(40)
= 480g
(c) To find the ratio of the three types of coffee in a third standard blend Z, formed by mixing equal weights of X and Y, we first need to find the total weight of X and Y that will be used to make Z. Since we are mixing equal weights of X and Y, the total weight of X and Y in Z will be:
800g + 800g = 1600g
The ratio of P coffee to Q coffee in Z can be found by adding the weights of P coffee in X and Y, and then dividing by the total weight of X and Y:
(150g + 40g) / 1600g = 0.1125
Similarly, the ratio of Q coffee to the total weight in Z can be found by adding the weights of Q coffee in X and Y, and then dividing by the total weight of X and Y:
(650g + 7(40g)) / 1600g = 0.5063
The ratio of R coffee to the total weight in Z can be found by adding the weights of R coffee in Y, and then dividing by the total weight of X and Y:
(12(40g)) / 1600g = 0.3
Therefore, the ratio of the three types of coffee in Z is approximate:
P : Q : R = 0.1125 : 0.5063 : 0.3
(d) To find the weight of type P coffee in 800g of Z, we can use the ratio of P coffee to the total weight in Z, which is 0.1125.
Therefore, the weight of P coffee in 800g of Z is:
0.1125 * 800g = 90g

given: trapezoid abcd where ba is congruent to cd angle abc is congruent to angle dcb
prove bd is congruent to ac
By the hypotenuse-leg congruence theorem (HL theorem), triangles ABD and CBD are congruent.
What is Trapezoid ?
A trapezoid is a four-sided polygon with at least one pair of parallel sides. It is also known as a trapezium in some countries.
To prove that BD is congruent to AC, we will use the fact that the opposite sides of a trapezoid are parallel.
Since AB and CD are parallel, and BC is a transversal, we know that angles ABC and DCB are supplementary (they add up to 180 degrees).
From the given information, we know that angle ABC is congruent to angle DCB. Therefore, both angles must be equal to 90 degrees (since their sum is 180 degrees).
Now consider the right triangles ABD and CBD.
In triangle ABD, we have a right angle at angle ABD, and we know that AB is congruent to CD (given).
In triangle CBD, we have a right angle at angle BCD, and we know that BC is congruent to BC (reflexive property).
We also know that angle ABD is congruent to angle BCD (since they are both equal to 90 degrees minus angle ABC/DCB).
Therefore, by the hypotenuse-leg congruence theorem (HL theorem), triangles ABD and CBD are congruent.
This means that BD is congruent to AC (the corresponding sides of congruent triangles are congruent).
Therefore, we have proven that BD is congruent to AC in trapezoid ABCD.

Determine if it is Exponential growth.
Use the information below to plug in the numbers to the formula. f(x)=a(1+or-r)^x
The value of x for each value of f(x) will lie between two consecutive whole numbers. List the whole numbers.
initial value: 1,000
decay rate: 20%
f(x) = 500
The value of x that corresponds to f(x) = 500 lies between 0 and 1. The whole numbers between 0 and 1 are 0 and 1, so the answer whole numbers are 0 and 1.
Describe Exponential Growth?Exponential growth is a mathematical concept that describes a process where a quantity grows at an increasing rate proportional to its current value. In other words, the larger the quantity, the faster it grows. This leads to a graph that is characterized by a rapid upward curve that becomes steeper and steeper over time.
Exponential growth is often represented by the equation y = abˣ, where y is the final amount, a is the initial amount, b is the growth factor or base, and x is the time or number of periods.
The function f(x) = a(1 - r)ˣ represents exponential decay, where "a" is the initial value, "r" is the decay rate as a decimal, and "x" is the time variable.
In this case, the initial value is 1,000, and the decay rate is 20%, or 0.20 as a decimal. Therefore, the equation for the function becomes:
f(x) = 1,000(1 - 0.20)ˣ = 800ˣ
To find the whole numbers that correspond to a value of f(x) = 500, we can set the equation equal to 500 and solve for x:
500 = 800ˣ
Taking the natural logarithm of both sides, we have:
ln(500) = ln(800ˣ)
Using the property of logarithms, we can bring down the exponent:
ln(500) = x ln(800)
Solving for x, we divide both sides by ln(800):
x = ln(500) / ln(800) ≈ 0.717
Therefore, the value of x that corresponds to f(x) = 500 lies between 0 and 1. The whole numbers between 0 and 1 are 0 and 1, so the answer is:
The whole numbers are 0 and 1.
