Answer:

105 ft.

Step-by-step explanation:

5 x 12 = 60

So 5 feet is 60 inches.

60 + 3 = 63

That makes the ridge 63 inches long.

When the lion went up the ridge, it traveled 63 inches.

When the lion went back down the ridge, it traveled another 63 inches, totaling 126 inches.

The lion did this 10 times.

126 x 10 = 1260

Divide 1260 by 12 to find the measurement in feet.

1260 ÷ 12 = 105

Answer:

y=5x/7-16/7

Step-by-step explanation:

make y the subject formulae

7y=5x-16

divide by 7 both sides

y=5x/7-16/7

here,

U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g),

now,

A-B = {a,b}

A n B = { c,d,e}

Answer:

It would be 98.12 dollars

Step-by-step explanation:

Hope this helps. :D

The original price of the car stereo before any discounts or taxes was approximately $187.14.

We have,

Gina paid $131 for the car stereo after it was discounted by 30%.

Let's represent the original price of the stereo as "x" dollars.

The discounted price would be 70% (100% - 30%) of the original price:

Discounted price = 0.70 * x

Given that Gina paid $131, we can set up the equation:

0.70 * x = 131

Now, solve for "x" by dividing both sides of the expression by 0.70:

x = 131 / 0.70

x ≈ 187.14

So, the original price of the stereo before the discount was approximately $187.14.

There was also 7% sales tax on the purchase.

To find the sales tax amount, we calculate 7% of the original price:

Sales tax = 0.07 * 187.14 ≈ 13.10

Now, to find the total original cost before the sales tax, we add the original price and the sales tax:

Total original cost = Original price + Sales tax

Total original cost ≈ 187.14 + 13.10 ≈ 200.24

Therefore,

The original price of the car stereo before any discounts or taxes was approximately $187.14.

Answer:

3.16

Step-by-step explanation:

3+3/4x=5/8

First multiply everything by 8 because of the LCM

You should get 24+6x=5

Next, Move the 24 to the other side.

You should get 6x=5-24

Now calculate it and you should have 6x=-19

Dividing both sides by 6 will give you -19/6 (duh)

You can turn that into a whole number which is 3.16

Step-by-step explanation:

-2u = 2i + 10j

V = 4i - 6j

(-2u).V = (2x4) - (10x-6)

= 8 - (-60)

= 68

f - 6 = -2f + 3(f - 2)

f - 6 = -2f + 3f - 6

f + 2f - 3f = -6 + 6

0 = 0

The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).

The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].

The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].

Overall, this function has a domain of

[-4, 1) U [-1, 2] U (2, 5]

(where U means "union" in the set-theoretic notion)

But this also simplifies to the interval [-4, 5].

These correspond to the first and last choices.

Ratios are used to show proportions of related quantities.

The ratio table equivalent to $10 per 15 tickets is:

[tex]\begin{array}{cc}{Amount}&{Tickets}&10&15&20&30&30&45&40&60\end{array}[/tex]

Given that:

Ratio = $10 per 15 tickets

Using proper notation, we have:

[tex]Ratio = 10:15[/tex]

To generate a ratio table, we simply multiply or divide each part of the ratio by the same unit.

For instance,

Multiply by 2

[tex]Ratio = 20:30[/tex]

Divide the original ratio by 5

[tex]Ratio = 2:3[/tex]

A possible ratio table is:

[tex]\begin{array}{cc}{Amount}&{Tickets}&10&15&20&30&30&45&40&60\end{array}[/tex]

The additive structure

From the above table, we can see that as the amount (x) increases by 10 units, the number of tickets (y) increases by 15 units.

So, the additive structure of the above table is:

[tex](x,y) \to (x_i+10,y_i + 15)[/tex]

The multiplicative structure

The multiplicative structure simply implies that the amount (x) and the number of tickets (y) be multiplied by the same unit.

So, the multiplicative structure of the above table is:

[tex](x,y) \to n(x_i,y_i)[/tex]
