t cost Andrea $50 per day to rent a moving truck and an additional $3 for
every mile that she drove it. If Andrea spent a total of $104 after renting the
ruck for 1 day, which equation shows how many miles Andrea drove?
O A.
104
3
= 50x
OB. 50+3x = 104
OC. 3+50x= 104

Answers

The equation that shows the miles Andrea drove is $104 = $50 + $3x.

What is the equation that shows the miles Andrea drove?

The total cost of renting the moving truck is a function of the cost to rent per day and the total miles driven. The cost to rent the truck per day is the fixed cost while the cost per mile is the variable cost.

Total cost = cost to rent per day + (cost per mile x total mile driven)

$104 = $50 + $3x

Use the stem and leaf plot graph to answer the question.

Answers

Answer:   13 days

====================================================

Explanation:

Count the number of leaves marked in green.

Row One: 2 leaves (1 and 8)Row Two: 3 leaves (3, 6, and 9)Row Three: 5 leaves (2, 3, 4, 6, 7)Row Four: 3 leaves (1, 6, and 8)

There are 2+3+5+3 = 13 leaves total. This represents tickets were sold on 13 days.

Each stem and leaf combines to form a different ticket count. For instance, the stem of 1 and leaf of 8 combine to get the value 18. So 18 tickets were sold on that particular day.

May runs 10/4 miles everyday .Beth runs 5/2 miles everyda.who runs further?

Answers

Answer:  They run the same distance

Explanation:

The fraction 5/2 turns into 10/4 when you multiply top and bottom by 2

5*2 = 10

2*2 = 4

Or you could use long division or a calculator to notice that

5/2 = 2.5

10/4 = 2.5

Both result in the same exact decimal value, so the fractions must be equal. Each person runs exactly 2.5 miles everyday.

Answers

Answer:

t(n) = 4n + 1058 minutes

Step-by-step explanation:

Initial value is 10 minutes and additional time is 4 minutes per week.

This is a linear function with

y-intercept b = 10slope m = 4

The formula for the time of run after n weeks is

t(n) = 4n + 10, where t(n) - run time after n weeks

Daily run time after 8 weeks is

t(8) = 4*8 + 10 = 58 minutes

Combined, there are 182 ​Asians, Africans,​ Europeans, and Americans in a village. The number of Asians exceeds the number of Africans and Europeans by 59. The difference between the number of Europeans and Americans is 14. If the number of Africans is​doubled, their population exceeds the number of Europeans and Americans by 16. Determine the number of​ Asians, Africans,​Europeans, and Americans in this village.

Answers

Answer:

Asians - 114, Africans - 28,​ Europeans - 27, Americans - 13

Step-by-step explanation:

Let

Asians - a, Africans - b,​ Europeans - c, Americans - d

Eqautions as per question

Combined, there are 182 ​Asians, Africans,​ Europeans, and Americans in a village.

a + b + c + d = 182

The number of Asians exceeds the number of Africans and Europeans by 59.

a = b + c + 59

The difference between the number of Europeans and Americans is 14.

c - d = 14 ⇒ c = d + 14

If the number of Africans is​doubled, their population exceeds the number of Europeans and Americans by 16

2b = c + d + 16 ⇒ 2b = d + 14 + d + 16 ⇒ 2b = 2d + 30 ⇒ b = d + 15

Substitute a, b and c into the first equation and solve for d

(b + c + 59) + b + c + d = 182d + 15 + d + 14 + 59 + d + 15 + d + 14 + d = 1825d + 117 = 1825d = 182 - 1175d = 65d = 65/5d = 13

Find the other variables

b = 13 + 15 = 28c = 13 + 14 = 27a = 28 + 27 + 59 = 114

We found that

Asians - 114, Africans - 28,​ Europeans - 27, Americans - 13

What is P(A, B, and C)? They are independent.

P(A) = .66

P(B) = .52

P(C) = .78

Answers

If each of A, B, and C are mutually independent, then

P(A and B and C) = P(A) P(B) P(C)

so that the probability of the three-way intersection is

P(A and B and C) = 0.66 × 0.52 × 0.78 = 0.267696 ≈ 0.27

Find the equation of the rational function ƒ whose graph satisfies the conditions: Horizontal asymptote is y = 3, vertical asymptote is x = –5, removable discontinuity at x = 2, x-intercept is 1.

Answers

A function assigns the values. The function is f(x) = (8x - 8)/(x² + 2x).

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

A rational function has a denominator and a numerator.

Vertical asymptotes are x-values that the function approaches but never touches. By setting the denominator to zero, we may discover the vertical asymptotes.

Since the vertical asymptote is x=-2 and x=0,  our denominator of the function will be

x(x+2) = x²+2x

Horizontal asymptotes are y values that the function approaches but never touches. Because the horizontal asymptote is y=0, the numerator's degree must be less than the denominator's degree. And because the x-intercept is equal to one, our numerator will be

x - 1

At the moment, The function can be assumed to be,

f(x) = (x - 1)/(x²+2x)

Next, we need to use the condition f(2)=1.   If we plug in x=2, f(x) should equal 1. But we need to multiply the right side of the function by some constant C.

The condition f(2)=1 must then be applied. If we substitute x=2, f(x) should equal 1. However, we must multiply the right side of the function by a constant C.

1 = C(2 - 1)/(2²+2(2))

Solve for C.

1 = C / 8

8 = C

So the function will be

f(x) = [8(x - 1)] / [(x² + 2x)]

f(x) = (8x - 8) / (x² + 2x)

Hence, the function is f(x) = (8x - 8)/(x² + 2x).

You wish to buy a new set of strings for your guitar. You phone five different
music shops and obtain a quote for a set of strings from each of them. The
average price charged by the five music shops is R225,00. If the first two music
shops both charge R180,00 for the strings, while the third and fourth shops
respectively charge R280,00 and R270,00, how much did the fifth music shop
charge for the strings?

Answers

Answer:

215,00.

Step-by-step explanation:

Average price = 22500

18000*2 + 28000 + 27000 + x = 22500*5

91000 + x = 112500

X = 21500

Answer:

R215,00

Step-by-step explanation:

Let x = amount the 5th music shop charges for the strings

[tex]\sf mean=\dfrac{\textsf{sum of all the numbers}}{\textsf{amount of numbers}}[/tex]

[tex]\implies \sf 225=\dfrac{180+180+280+270+x}{5}[/tex]

[tex]\implies \sf 225\cdot 5=910+x[/tex]

[tex]\implies \sf 1125=910+x[/tex]

[tex]\implies \sf x=1125-910[/tex]

[tex]\implies \sf x=215[/tex]

Therefore, the fifth music shop charged R215,00 for the strings.
