A shopper bought 6 shirts and 8 hats for $700. A week later, at the same prices, he bought 9 shirts and 6 hats for $660. What was the cost of one shirt?

Answers

Answer:

Cost of one shirt = $ 30

Step-by-step explanation:

Let cost of 1 shirt = s

Cost of 1 hat  = h

A shopper bought 6 shirts and 8 hats for $700.

6s + 8h = 700      -------------------(I)

A shopper bought 9 shirts and 6 hats for $660

9s + 6h = 660    -----------------(II)

Multiply equation (I) with 9 and multiply equation (II) with (-6) and then add. SO, now 's' will be eliminated and we can find the value of 'h'

(I) * 9                54s + 72h  = 6300

(II)*(-6)            -54s  - 36h = - 3960   {Now add}

                                 36h = 2340

                                     h = 2340/36

                                     h = 65

Cost of one hat  =  $ 65

Substitute h = 65 in equation (I)

6s + 8 * 65 = 700

6s  + 520   = 700

            6s = 700 - 520

            6s = 180

               s = 180/6

               s = 30

Cost of one shirt = $ 30

Answer: One shirt is $30

What would the exponential equation be ?

Answers

Answer:

The equation of the exponential function will be:

[tex]f\:\left(x\right)\:=\:ab^x[/tex]

          [tex]=\:\frac{3}{2}\left(2\right)^x[/tex]

Step-by-step explanation:

Given the table

Day         Bacteria

1               3

2              6

3              12

4              24

5              48

as

the x values have the same increment i.e. +1

and

the y values have common ratio i.e. 6/3 = 2, 12/6=2, 24/12=2

so it is indeed an exponential function

As we know that the exponential function is of the form

[tex]f\:\left(x\right)\:=\:ab^x[/tex]

As we know that the y-intercept of [tex]f\:\left(x\right)\:=\:ab^x[/tex] is (0, a).

so

[tex]\frac{3}{a}=2[/tex]        ∵ common ratio = successor y-value ÷ previos y-value

[tex]a=\frac{3}{2}[/tex]

so the value of a will be: 3/2

We also know that the common factor i.e. multiplier is 2 in this table, we know the value for b is 2.

Therefore, the equation of the exponential function will be:

[tex]f\:\left(x\right)\:=\:ab^x[/tex]

          [tex]=\:\frac{3}{2}\left(2\right)^x[/tex]

Jordan throws a ball from a cliff 12 feet above the ground with an initial velocity of 32 feet per second. In the following functions, h(t) represents the height of the ball above the ground, in feet, with respect to time, t, in seconds, after the ball was thrown. Which of the following functions models the amount of time the ball is in the air?

h(t)= -4(t-1)^2 +3
h(t)= -16(t-1)^2 -4
h(t)= -16(t-1)^2 +12
h(t)= -16(t-1)^2 +28

Answers

Answer:

Your answer will be the third function

Step-by-step explanation:

The base function you need to know is h(t)= 1/2at^2

Your acceleration in this problem is going to be gravity which they give to you, 32 feet per second squared. Since the ball is falling, it means it will have negative acceleration. Now you have the equation h(t)= -16t^2. The final step is to add the initial height from which the ball was dropped giving you: h(t)= -16t^2 +12

Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her
salary on expenses each year, then how much money does Sandy have to spend on
expenses? Round your answer to the nearest whole number.

Answers

Answer:

Step-by-step explanation:

50,000 * 60%= 30,000

If Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Given that, Engineer Sandy earns a salary of $50000 per year. If Sandy spends each year 60% of her income on expenses,

We have to find the amount Sandy has to spend on expenses,

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

The amount spend on the expenses is,

Expenses = 60% of the salary

Expenses =60/100 × $50000

Expenses = 30,000

Thus, if Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.

The slope of the line is 3

The difference between the consecutive term of the sequence is (1, 3)

To get the slope of the graph, we will use the coordinate points (2, 10) and  (3, 13)

Slope = 13-10/3-2

Slope = 3/1

Slope = 3

Hence the slope of the line is 3

The difference in the term for the x-coordinate is given as:

x = 3 - 2 = 4 - 3  = 5 -4  = 1

The difference in the term for the y-coordinate is given as:

Answers

Answer:600 miles

Step-by-step explanation:

Hello!  

So you know that 348 miles is equal to 58% so you want to figure out what 1% of the total trip is

348 / 58 = 6

You know that 1% of the trip is 6 miles so now to figure out what the total trip is you multiply 6 by 100

6 * 100 = 600

So you know that the total length of the trip is 600 miles long.

A rectangular carpet measures 12 m by 5 m.
Part of the carpet is covered by a square rug of length 2 m.
What fraction of the carpet is covered by the rug? Give your answer in its simplest form.

Answers

I'm pretty sure the answer is 1/15 or 4/60 because the whole carpet measures 60m and the covered part's area is 4m and that would be 4/60 but simplified 1/15.  Sorry if this is wrong!

To find the fraction of the carpet covered by the rug, we need to determine the area of the rug and divide it by the total area of the carpet.

The area of the square rug can be calculated by squaring its side length: 2m x 2m = 4m². The total area of the rectangular carpet can be found by multiplying its length and width: [tex]12m x 5m = 60m²[/tex]. To find the fraction, divide the area of the rug by the area of the carpet: 4m² / 60m².

To simplify the fraction, we can find the greatest common divisor (GCD) of 4 and 60, which is 4. Dividing both the numerator and denominator by the GCD, we get: [tex]4m² ÷ 4 / 60m² ÷ 4 = 1m² / 15m²[/tex] . Therefore, the fraction of the carpet covered by the rug is 1/15, which means that 1/15th of the carpet is covered by the rug.

Answers

Answer:

1+1=magelan

2plus2 lapulapu

Answer:

b and d

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 6) and (x₂, y₂ ) = (- 2, 2) ← 2 points on the line

m = [tex]\frac{2-6}{-2+3}[/tex] = - 4

Using (a, b ) = (- 3, 6 ), then

y - 6 = - 4(x - (- 3)), that is

y - 6 = - 4(x + 3) → d

Using (a, b ) = (- 2, 2 ), then

y - 2 = - 4(x - (- 2)) , that is

y - 2 = - 4(x + 2) →b
