The following conclusions can be drawn from the circle graph:
Cable Car is the preferred transportation for 75 residents. (27% of 300 = 81 residents)
Together, Streetcar and Bus are the preferred transportation for 25% of residents. (15% + 10% = 25% of 300 = 75 residents)
The other two statements are incorrect:
Bicycle is the preferred transportation for 8% of residents, not 30. (8% of 300 = 24 residents)
Together, Bus and Bicycle are the preferred transportation for 18% of residents, not 54. (10% + 8% = 18% of 300 = 54 residents)

Answer:
790,000
Step-by-step explanation:
The 5 represents the number by itself so it would be
10x10x10x10x10=100,000
7.9x100,000=790,000
Step-by-step explanation:
if you multiply something by 10 = 10¹, you move the decimal point 1 position to the right (and fill up with a 0, if necessary).
if you multiply something by 100 = 10², you move the decimal point 2 positions to the right (and fill up with 0s as needed).
if you multiply something by 1000 = 10³, you move the decimal point 3 positions to the right (and fill up with 0s as needed).
...
you see the pattern ?
so, when multiplying by 10⁵ (100,000) we shift the decimal point 5 pairings to the right and fill up with 0s as needed.
therefore,
7.9 × 10⁵ = 790,000.-

y equals one fourth times x minus 2
y equals negative one fourth times x plus 4
y = 4x − 2
y = −4x + 3
Answer:
y equals one fourth times x minus 2
Step-by-step explanation:
Equation of straight line:
y =ax + b
Find a and b by selecting at random two pairs from among the plots.
(0, -2)
-2 = a·0 +b
b =-2
(4, -1)
-1 = a.4 +(-2)
-1 =4a -2
1 = 4a
a = 1/4
Equation is : y=(1/4)x -2 y equals one fourth times x minus 2
Option (A) y equals one fourth times x minus 2.

Determine the line of reflection.
Reflection across the x-axis
Reflection across the y-axis
Reflection across y = −4
Reflection across x = 6
Answer:
x = 6
Step-by-step explanation:
We can see that the figures are symmetrical around the vertical line:
[tex]x = 6[/tex],
meaning that one figure reflected across that line results in the other figure.
Therefore, x = 6 is the line of reflection.

John puts $70 in a savings account that earns 6% annually. The interest is not compounded. How many years will it take John to make at least $100 in interest?
Answer:
24 years
Step-by-step explanation:
If interest is not compounded, it is called simple interest.
Simple interest is calculated as a percentage of the principal amount and is applied only to the principal.
The formula for simple interest is:
[tex]\boxed{\sf I = Prt}[/tex]
where:
I = Total interest earned.P = Principal amount.r = Interest rate (in decimal form).t = Time (in years).The given values are:
I = $100P = $70r = 6% = 0.06Substitute the given values into the formula and solve for t:
[tex]\implies \sf 100=70 \cdot 0.06 \cdot t[/tex]
[tex]\implies \sf 100=4.2 t[/tex]
[tex]\implies \sf 4.2 t=100[/tex]
[tex]\implies \sf \dfrac{4.2 t}{4.2}=\dfrac{100}{4.2}[/tex]
[tex]\implies \sf t=23.8095238...\;years[/tex]
We need to round up to the next year. Therefore, it will take 24 years for John to make at least $100 in interest.
Answer:
approx. 24 years
Step-by-step explanation:
The formula to find the simple interest is:
[tex]\sf I= \frac{prt}{100}[/tex]
Here,
I ⇒ Interest ⇒ $ 100
p ⇒ principle ⇒ $ 70
r ⇒ rate ⇒ 6
t ⇒ time ( years )
Let us find the time taken using the formula.
[tex]\sf I= \frac{prt}{100}\\\\100=\frac{70*6*t}{100} \\\\100*100=420t\\\\10000=420t\\\\23.8\: years=t\\\\approx. \:24 \:years=t[/tex]

Polygon ABCD is drawn with vertices A(−4, −4), B(−4, −6), C(−1, −6), D(−1, −4). Determine the image coordinates of B′ if the preimage is reflected across y = 3.
Answer:
The image coordinates of B' will be (-4, 12).
Step-by-step explanation:
The distance from y = -6 to y = 3 is 9, so we add 9 × 2, or 18 units to the original y-coordinate of B and keep the x-coordinate the same. So we have
B'(-4, 12).

How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.The slope and the intercept for the function in this problem are given as follows:
Slope of -1.22, meaning that for an increase of one degree Fahrenheit, the predicted decrease in the cost is of $1.22.Intercept of 96.2, meaning that the predicted heating cost for a month with temperature of 0 ºF is of $96.20.Hence, the predicted cost for a month with temperature of 25ºF is given as follows:
y = -1.22(25) + 96.20 = $65.70.

Which math ratio represents efficiency?
A). Fi x do/Fo x di
B). Fo x di/Fi x do
C). Fi x di/Fo x do
D). Fo x do/Fi x di
The math ratio that represents efficiency is option D). Fo x do / Fi x di.In this ratio:Fi represents the input force or input quantity.di represents the input distance or input time.Fo represents the output force or output quantity.do represents the output distance or output time.Efficiency is typically calculated by comparing the output to the input. In the case of mechanical systems, it is often measured as the ratio of output work or energy to input work or energy.Therefore, the ratio Fo x do / Fi x di represents the output work or energy divided by the input work or energy, which is commonly used to determine efficiency in various contexts.
Which of the following equations represents a linear function?
x = −2
y = 5x − 6
y equals negative one fifth times x squared
−3x + 2 = 4
Answer:
The equation that represents a linear function is:
y = 5x - 6
Step-by-step explanation:
This equation has a constant rate of change, which means that for every unit increase in x, there is a consistent and constant increase or decrease in y. This is a characteristic of linear functions, where the relationship between x and y is a straight line.
y = 5x - 6 is represents a linear function.

2√(4)√(5/4)3√(1)√(2/1)2√(1)√(3/1)How do we approximate the square roots using the perfect squares?To approximate the square roots using the perfect squares method, we need to find the largest perfect square that is less than each of the given terms, and then simplify.
For 2√5:
The largest perfect square less than 5 is 4, so we can write 2√5 as 2√(4)√(5/4).
Simplifying, we get:
2√(4)√(5/4)
= 2(2)√(5/4)
= 4√(5/4)
= 4√5/√4
= 4√5/2
= 2√5.
For 3√2:
The largest perfect square less than 2 is 1, so we can write 3√2 as 3√(1)√(2/1).
Simplifying, we get:
3√(1)√(2/1)
= 3(1)√(2/1)
= 3√2/√1
= 3√2.
For 2√3:
The largest perfect square less than 3 is 1, so we can write 2√3 as 2√(1)√(3/1).
Simplifying, we get:
2√(1)√(3/1)
= 2(1)√(3/1)
= 2√3/√1
= 2√3.

A grocery store receives a crate with contents that weigh 180 pounds. The contents consist of six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes. Choose an equation that represents the number of bags of potatoes in the crate.
A: 6(10) + 180 = 5x
B: 10 + 6 + 5x = 180
C: 180 = 5 + 60x
D: 6(10) + 5x = 180
Answer:
6(10)+5x=180
Step-by-step explanation:
This is because there are 6 10-pound bags that we know of, so it would be 6(10).
Then, there are an unknown number of 5-pound bags, in which the variable would be x, so it would be 5x.
Lastly, the content weighs 180 pounds, so that's what the equation would be equal to.

In order to find this out, we first take 3/5 and convert it into a decimal by dividing the numerator by the denominator
3 ÷ 5 = 0.6
Then, we can set up this equation to figure out how many gallons of gasoline were used:
0.6 x 61.5 = 36.9
Answer: 36.9 gallons used

Answer:
The area of the given figure is 142.5 sq. cm.
Step-by-step explanation:
The area of a parallelogram is given by the base multiplied by the height. The base in the given figure is 15 cm whereas the height is 9.5 cm.
15 × 9.5 equals 142.5
Hence, the area is 142.5 sq. cm.
