Heather paid $2,022.30 for a computer. If the price paid includes a 7% sales tax, which of the following equations can be used to determine the price of the computer after tax? (Let x represent the cost of the computer and y represent the total cost after tax.)

Answer:

2.94

Step-by-step explanation:

3.29 - 35/100 = 2.94

Answer:

x = 20°

Step-by-step explanation:

So basically, since the 2 values are on the opposite side of an "x," you just set the 2 values each to each other and solve for x.

6x - 20 = 100

+20 +20

6x = 120

÷6 ÷6

x = 20

Answer:

$616 in debt

Step-by-step explanation:

5.5% is equal to 0.055 so you multiply that by $1400 to get $77.

$77 is the interest rate.

You then multiply $77 by 8 months.

Answer:

65

Step-by-step explanation:

I'm not completely sure if this is correct but this is what I got:

cherry candies: c ; grape candies: g

the ratio of the cherry candies to the grape candies is 3:5 so c/g=3/5 so c=3/5g

when you eat 1 cherry candy and half of the grape candies the ratio becomes (c-1)/(g/2)=7/6

I used substitution so now it becomes (3/5g-1)/(g/2)=7/6 if you solve this g will equal to 60. This number means that there was 60 grape candies originally. With this,  you can solve for the number of cherry candies that you originally had (which is 36 because the ratio is 3:5)

so now you halve the number of grape candies which is 30 and take one off from the cherry candies which is now 35 (cherry:grape = 7:6 = 35:30)

there are now 65 candies altogether

A ratio shows us the number of times a number contains another number. The total number of candies that are left in the bag is 65.

A ratio shows us the number of times a number contains another number.

The ratio of cherry candies to grape candies in a bag is 3:5. Therefore, we can write the ratio of the cherry to grapes as,

Cherry / grapes = 3/5

Multiply both the numerator and the denominator of the ratio with x,

Cherry / grapes = 3x/5x

Therefore, the number of Cherry and grapes in the initial was 3x and 5x, respectively.

Further, it is given that your friend eats half of the grape flavored candies and only one cherry flavored candy, the ratio of cherry to grape candies is 7:6. Therefore, we can write the ratio as,

[tex]\dfrac{3x - 1}{\frac{5x}{2}} = \dfrac{7}{6}[/tex]

Now, to get the real numbers we can write,

[tex]\dfrac{3x - 1}{\frac{5x}{2}} = \dfrac{7}{6} \times \dfrac{y}{y}\\\\\dfrac{3x - 1}{\frac{5x}{2}} = \dfrac{7y}{6y}[/tex]

Thus, we got two equations,

3x - 1 = 7y

5x/2 = 6y

Solving the second equation for x,

5x/2 = 6y

5x = 12y

x = 12y/5

Substitute the value of x in the first equation,

3x - 1 = 7y

3(12y/5) - 1 = 7y

y = 5

Furthermore, the total number of candies can be written as,

6y + 7y

= 6(5) + 7(5)

= 30 + 35

= 65

Hence, the total number of candies that are left in the bag is 65.

Thus, the 2nd or lower graph represents the graph of  [tex]y\:=\:4^x[/tex].

The correct graph is also attached below.

Step-by-step explanation:

Given the function

[tex]y\:=\:4^x[/tex]

Let us determine the y-intercept by setting x=0, and then determining the corresponding y-value.

now substituting x = 0 in the function

[tex]y=\:4^0\:[/tex]

Apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]

[tex]y = 1[/tex]

Thus, the y-intercept is (0, 1)

Now, if we closely observe the 2nd graph or lower graph, the y-intercept of the lower graph is (0, 1)

Thus, the 2nd or lower graph represents the graph of  [tex]y\:=\:4^x[/tex].

The correct graph is also attached below.

Answer:

D) The car stops at a distance from the starting point because the portion shows a constant function away from the starting point.

Step-by-step explanation:

For this case, the first thing you should keep in mind is the following definition:

d = v * t

Where,

d: distance

v: speed

t: time

For the portion of the chart labeled J we have:

The time increases

The distance is the same

We have then that the speed is zero.

Therefore, the car is stopped at a distance far from the starting point.

Given:

The diameter of a bicycle wheel is 28 inches.

To find:

The circumference of the wheel as it relates to diameter.

Solution:

We have,

Diameter: [tex]d=28\text{ inches}[/tex]

We know that,

Radius: [tex]r=\dfrac{d}{2}[/tex]

[tex]r=\dfrac{28}{2}\text{ inches}[/tex]

The circumference of a circle is

[tex]C=2\pi r[/tex]

Putting [tex]r=\dfrac{28}{2}[/tex], we get

[tex]C=2\times \pi \times \dfrac{28}{2}[/tex]

[tex]C=28\times \pi[/tex]

Therefore, the correct option is (H).

Answer:

The second term is 12.6

Step-by-step explanation:

Let us solve the question

∵ The recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11

∵ f(1) = 4

→ To find the 2nd term, sunstitute n by 2

∵ n = 2

∴ f(2) = 0.4 · f(2 - 1) + 11

∴ f(2) = 0.4 · f(1) + 11

→ Substitute f(1) by 4

∵ f(2) = 0.4 · 4 + 11

→ Simplify the formula

∴ f(2) = 1.6 + 11

∴ f(2) = 12.6

∴ The second term is 12.6
