tester [92]

Answer:

22.99

Step-by-step explanation:

Well, $24.99 dollars no matter how many miles. if she drove 200 miles, we will say that x represents miles driven. So, the cost will be $24.99+ $0.10x

to solve, substitute 20 for x.

$24.99 + $0.10(20)

$24.99 + $2

$24.99

Your answer is 22.99 dollars!

Write the vertex form of the equation of the parabola which has a vertex of (0,0) and contains the point (2,-2)
Anettt [7]
\bf \qquad \textit{parabola vertex form}\\\\&#10;\begin{array}{llll}&#10;\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\&#10;x=a(y-{{ k}})^2+{{ h}}&#10;\end{array} \qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\&#10;-------------------------------\\\\&#10;y=a(x-{{ h}})^2+{{ k}}\qquad &#10;\begin{cases}&#10;h=0\\&#10;k=0&#10;\end{cases}\implies y=a(x-0)^2+0&#10;\\\\\\&#10;y=ax^2\qquad &#10;\begin{cases}&#10;x=2\\&#10;y=-2&#10;\end{cases}\implies -2=a2^2

solve for "a", to get the coefficient, and then plug it back in the equation.

Patterinsin the multiplication table
victus00 [196]
1. The numbers in the section to the right of the diagonal (white squares) are the same as in the section to the left of the diagonal. Or, in other words, the numbers in the darker shaded section are repeated in the lighter shaded section.

2. The 10 × table is just the 10s in order (10, 20, 30, 40 and so on).

3. The 5 × table has numbers ending in 5 and 0 alternately, while the first digit increases every 2 numbers.

4. The 9 × table has the units decreasing by 1 and the 10s increasing by 1 each time (up to 10 × 9).

5. The numbers in the 3 × table have the sum of their digits coming to 3, then 6, then 9. This pattern repeats throughout the table: e.g. 12: 1 + 2 = 3; 15: 1 + 5 = 6, 18: 1 + 8 = 9.

Hope my answer helped u :)

Say you are at a grocery store and find an item without a listed unit price. How would you calculate the unit price for this ite
Aneli [31]

Answer:

Unitary Method

Step-by-step explanation:

If the item is not listed with the unit price we can use different methods to calculate its unit price.

Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.

We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.

For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:

6 pounds costs $7.00

1 pound costs: \frac{7}{6}=1.17 dollars.

And that is how we calculate the price of each unit.
