On the map, the scale is 1inch=125 miles.what is the actual distance between two cities if the distance on the map is 4 inches
Answer:
The total distance between the two cities in miles it 500 miles.
Step-by-step explanation:
In this example, we know that 1 inch on a map equals 125 miles in real life. The distance between 2 cities is 4 inches. We need to find the distance between these two cities in miles.
125 x 4 = 500
Therefore, the total distance between the two cities in miles it 500 miles.

A new car is purchased for 19900 dollars. The value of the car depreciates at 7.5% per year. What will be the value of the car after 8 years? Round to the nearest hundredth.
Answer:
$10665,64
Step-by-step explanation:
S=19900*(1-(7,5/100))^8=10665, 64
Answer:10665.64
Step-by-step explanation: Exponential Functions:
y=ab^x
A= starting value = 19900
r=rate = 7.5%=0.075
Exponential Decay:
b=1-r=1-0.075=0.925
Write Exponential Function:
y=19900(0.925)^x
Plug in time for x:
y=19900(0.925)^8
y= 10665.6404317

118 + 560 is the same as
100 +
Answer:
578
Step-by-step explanation:
118
+560
answer:678
678-100=578
The sum of 118 and 560 is the same as adding 100 to 578.
To find the sum of 118 and 560, we can add the hundreds, tens, and ones separately.
Starting with the ones, 8 + 0 = 8.
Then, moving on to the tens, 1 + 6 = 7.
Finally, adding the hundreds, 1 + 5 = 6. Combining these results, we get 678 as the sum.
However, if we add 100 to 578, we get 678, which is the same as the previous result. This happens because when we add 100 to the sum of 118 and 560, we essentially increase the hundreds place by 1 while keeping the tens and ones the same.
The final answer is 578.

Joey's age is 3 less than twice his brother's age. Joey is 13 years old. How old is his brother?
Joey's age is 3 less than twice his brother's age. Joey is 13 years old. How old is his brother?
Answer:Joey's brother is 8 years old.
Solution and Explanation:Let's assume that:
Joey's brother's age = x years oldJoey's age = y years oldAs per the provided information, we are given that Joey's age is 3 less than twice his brother's age, we can write an equation:
[tex]\Large\qquad\quad\bigstar\:\:\boxed{\rm{\:\:y = 2x - 3\:\:}}[/tex]
We know that Joey is 13 years old. So we can substitute 13 for Joey's age in the equation and solve for x:
[tex]\Large\begin{aligned}\rm{13}&=\rm{2x - 3}\\\rm{13 \red{+3}}&=\rm{2x - \cancel{3 \red{+3}}}\\\rm{16}&=\rm{2x}\\\rm{\dfrac{16}{\red{2}}}&=\rm{\dfrac{\cancel{2}x}{\cancel{\red{2}}}}\\\bold{8}&=\rm{x}\end{aligned}[/tex]

Answer:
45.1 cm^2
Step-by-step explanation:
We can break up the area of quadrilateral ABCD into the sum of the areas of right triangle ABD and triangle BCD.
Triangle ABD is a right triangle, so the legs can be used as base and heightto find the area.
area of triangle ABD = bh/2
area of triangle ABD = (AD)(AB)/2
sin <ADB = opp/hyp
sin 55 = AB/10
AB = 10 sin 55
cos <ADB = adj/hyp
cos 55 = AD/10
AD = 10 cos 55
area of triangle ABD = (10 cos 55)(10 sin 55)/2
area of triangle ABD = 23.5 cm^2
Triangle BCD is a scalene triangle. We know the measures of 2 angles and the length of the included side.
Find the measure of angle C.
m<BDC + m<CBD + m<C = 180
44 + 38 + m<C = 180
m<C = 98
Use the law of sines to BC.
BD/(sin C) = BC/(sin <BDC)
10/(sin 98) = BC/(sin 44)
BC = (10 * sin 44)/(sin 98)
BC = 7.01485
Now use BC and m<CBD to find the length of the altitude from C to side BD. Call the altitude h.
sin 38 = opp/hyp
sin 38 = h/BC
sin 38 = h/7.01485
h = 7.01485 * sin 38
h = 4.3188
Now use BD as the base and h as the height to find the area of triangle BCD.
area of triangle BCD = base * height/2
area of triangle BCD = BD * h/2
area of triangle BCD = 10 * 4.3188/2
area of triangle BCD = 21.6 cm^2
Now we add the areas of the triangles.
area of quadrilateral ABCD = 23.5 cm^2 + 21.6 cm^2
area of quadrilateral ABCD = 45.1 cm^2

Answer:
C. The city population increases by 1000 every year.
Step-by-step explanation:
A linear function of time means that over time, the city's population also changes and it is like a relationship between time and the growth. A and B only says that during that one year, it increased by 1000 so it is a temporary change and no growth was mentioned. C and shows that every year, there is a steady change (1000 per year) so it is a linear function. D's increase would be too drastic as the 10% increase would increase so it would not be a steady line so it is not a linear function.

the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.

Help!Write the equation in slope- intercept form of the line that passes through (−1, 11) and is parallel to the graph of y = −8x − 2
Answer:
y = -8x + 3
Step-by-step explanation:
plug in the point and the slope into the slope intercept formula (y=mx+b)
the slope will be the same since you want the line to be parallel
11 = -8(-1) +b now solve for b
11 = 8 + b
-8 -8
3 = b
now write the equation with only the slope and the y intercept
y = -8x + 3
The equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.
What is the slope intercept form of a line?The slope intercept form of a line is given by -
y = mx + c
m is the slope of line
c is the y - intercept
Given is a line that passes through (-1, 11) and is parallel to the line -
y = − 8x − 2.
Since, the line is parallel to the line → y = − 8x − 2, therefore, their slope will be same and is equal to m = - 8.
Now, in the slope intercept form, assume that the equation of line looks like -
y = - 8x + c
Now, the line passes through the point (-1, 11), we can write -
11 = -8 x -1 + c
11 - 8 = c
c = 3
Hence, we can write the equation of the line as -
y = - 8x + 3
Therefore, the equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.
