Answer:

112.5

Step-by-step explanation:

total discount: 25%

Answer:

Step-by-step explanation:

150*15% off =22.50 off total 127.50. Then he gets the 10% off 127.50*10%= 12.75 off total cost $114.75

It may look like 25% off at once, but most stores will do the discounts separately so they don't lose too much money.

Given:

Initial value of car = 20,000

Depreciation or decreasing rate = 10% = 0.10

To find:

The equation that gives the value of the car.

Solution:

It is given that the value then depreciates or decreases by 10% of in initial value each year. It means the depreciation value is same for each year, i.e., 10% of initial value.

[tex]10%\text{ of }20000=\dfrac{10}{100}\times 20000[/tex]

[tex]10%\text{ of }20000=2000[/tex]

So, the value of car decreased by 2000 per year.

Let y be the value of can after x years.

Then, the value decreased in x years is 2000x.

So, the values of the car is

[tex]y=20000-2000x[/tex]

Therefore, the required equation is [tex]y=20000-2000x[/tex].

Answer: 137,375,958

Step-by-step explanation:

Exponential growth equation:

[tex]y=A(1+r)^x[/tex] , where A = initial population , x= time , r =rate of growth.

As per given: r = 1.7% = 0.017

Population of Mexico in 2003 : A= 104900000

In 2019 , x = 2019-2003 = 16

Population in Mexico :  [tex]y=104900000 (1+0.017)^{16}=104900000 (1.017)^{16}[/tex]

[tex]=104900000 (1.30958968823)\approx137375958[/tex]

Population of Mexico in 2019 = 137,375,958

Answer:

34 km/h

Step-by-step explanation:

speed = distance/time

Distance = 17km

Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours

So

speed = 17/0.5

speed = 34 km/h

Answer:

Eleven digits for toll calls became standard in all of North America by the end of 1994 to allow introduction of "interchangeable NPA codes" – area codes that did not have a 0 or 1 as the middle digit and could therefore be confused with the central office code – after January 1, 1995.

Step-by-step explanation:

Answer:

x = -8/3 or 7/2

Solution:

6x^2 - 5x = 56

6x^2 - 5x - 56 = 0

6x^2 -21x +16x - 56 = 0

3x(2x-7) + 8(2x-7) = 0

(3x + 8)(2x-7) =

3x + 8 = 0  or 2x - 7 = 0

x = -8/3 or 7/2

Answer:

y = -1/5x + 5

Step-by-step explanation:

Since this is written in slope-intercept form, you need to follow this form:

y = mx + b

(where m is the slope and b is the y-intercept)

To find the slope, you need to do (rise/run) or (change in y/change in x) with (5, 4) and (15, 2):

(4 - 2) / (5 - 15)

= 2 / -10

= -1/5

so m = -1/5

To find the y-intercept, you just need to plug one of the points into the equation with the slope:

y = -1/5x + b

= 4 = -1/5(5) + b

= 4 = -1 + b

= b = 5

so b = 5

Now, you put it all together:

y = -1/5x + 5

Answer:

0.7

Step-by-step explanation:

zero and seven TENths. the place value of the 7 is tenths so on the bottom of the fraction will be 10. i'm bad at explaining so sorry.

the decimal equivalent of 7 / 10 is 0.7.

To find the decimal equivalent of 7 / 10, we divide the numerator ( 7) by the denominator ( 10).

When we perform the division, 7 ÷ 10, we get 0.7.

Therefore, the decimal equivalent of 7 / 10 is 0.7.

In decimal form, the number 0.7 represents 7 tenths or 7 parts out of 10. It indicates that the numerator ( 7) is 7 / 10th of the denominator ( 10). This decimal representation makes it easier to compare the fraction with other decimal numbers and perform arithmetic operations using decimals.

I did Geometry, I got A+

Answer:

[tex]y+1=\frac{-2}{3} (x+4)[/tex]

Step-by-step explanation:

you can use the equation point-slope of a line

(y-y1)= m(x-x1)

m is the slope =rise /run

to get from the lower point  on the line to the other you rise 4 units and run -6 units so m= -4/6= -2/3

now that you have the slope pick you need one point

pick any poin on the line for example (-4, -1)

now you substitute into the point-slope equation point (-4,-1) and slope -2/3

(y+1)= -2/3(x+4)

in standard form will be

y=[tex]\frac{-2x}{3} -\frac{2*4}{3} -1[/tex]

y=[tex]\frac{-2x}{3}- \frac{5}{3}[/tex]

Answer:

The distance between the two is 465 meters

Step-by-step explanation:

We first need to set up a triangle that shows the relative position and distances of the two friends

Please check attachment for this

To get this distance, which represents the hypotenuse of the triangle, we make use of Pythagoras’ theorem

Mathematically;

Pythagoras’ theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Thus;

D^2 = 256^2 + 388^2

D^2 = 216,080

D = √216,080

D = 464.84 which is approximately 465 m
