Answer:

  (0, 5), (10, 0)

Step-by-step explanation:

It can be useful to graph the equation and plot the points. Alternatively, you can evaluate the equation at the offered points.

Right away, you will notice that x must be even if y is to be an integer. The first point is the y-intercept, which the equation tells you is (0, 5). Then the only remaining candidate point is (10, 0), which also satisfies the equation:

  0 = (-1/2)(10) +5 = -5 +5

A girl scout leader rented a bus for a trip to the museum. The bus company charged $275 plus $.35 for each mile traveled over 35
slava [35]

Answer: The trip was 440 miles

Step-by-step explanation:

A girl scout leader rented a bus for a trip to the museum.

Let x represent the number of miles

traveled over 350 miles.

Let y represent the total cost of travelling x miles

The bus company charged $275 plus $.35 for each mile traveled over 350 miles. This means that for x miles, the cost will be

y = 275 + 0.35x

If the bus trip cost $429, it means that y = 429

To determine the number of miles,we will substitute y = 429 into the equation. It becomes

429 = 275 + 0.35x

0.35x = 429 - 275 = 154

x = 154/0.35 = 440

x = 440 miles

List 0.5 1/5 0.35 12/25 4/5 from least to greatest
Anika [276]
One way is to make them all decimals or all fractions:

.5   .2  .35  .48  .80  are the numbers above changed to decimals.
I will make them the same length (two digit past the decimal point) to compare
.50   .20  .35  .48 and .80

Now it is easy to put them in order

.2  .35  .48   .5  and .80

Let's put them into all fractions

5/10   1/5   35/100   12/25 and 4/5

Instead of finding a common denominator let's try this:
Think of them as test scores - the person who got 1 out 5 did the worst
Next came the person who got only 35 out of 100 - they only did better than the one above (1/5)
12/25 is almost 1/2 but a little below half the questions right
5/10 is exactly half the questions right (so it is bigger than 12/25 by a little).
4/5 is the best score (and the only one who passed).
So 1/5, 35/100, 12/25, .5 and 4/5 are in order least to greatest and match the answer above in bold.

What is the area?? Please help
Olegator [25]

Answer:

<h3>324 ft²</h3>

Step-by-step explanation:

We have the triangle and the rectangle.

The formula of an area of a triangle:

A_{\triangle}=\dfrac{1}{2}bh

b - base

h - height

The formula of an area of a rectangle:

A_{\boxed{\ }}=lw

l - length

w - width

We have b = 24 ft, h = 7 ft, l = 24 ft and w = 10 ft.

Substitute:

A_\triangle=\dfrac{1}{2}(24)(7)=(12)(7)=84\ ft^2

A_{\boxed{\ }}=(24)(10)=240\ ft^2

The area of the figure:

A=A_{\triangle}+A_{\boxed{\ }}

Substitute:

A=84+240=324\ ft^2
