A cheater travels at a rate of 90 ft./s the distance d traveled by the cheetah is a function of seconds traveled t right rule fo

HACTEHA [7]

So the equation for this would be y= 90x where y would be the distance in feet covered in x seconds and x would be seconds. So to find out the distance covered in 25 seconds you would plug in 25 for x.

y= 90(25)
y= 2250

So to answer the question you would say that the cheetah would cover 2,250 feet in 25 seconds.

Convert the following equation into<br> standard form.

kicyunya [14]

Answer:

7x+9y=45

Step-by-step explanation:

Standard equations always mean that you have to get x and y on one side so that they equal the coefficient.

Do this by adding the fraction that is combined with x to the other side where y is. The equation should now read $\frac{7}{9} x + y = 5$

Standard form cannot have fractions, so now you must multiply by the denominator (9) on both sides of the equation in order to cancel it out. Don't forget to multiply EACH variable by 9. This leads you to the answer.

The length of the diogonals of a rectangular garden is 34m. If it's longer side measures 30m, find the perimeter of garden.

MakcuM [25]

Answer:

92 m

Step-by-step explanation:

Use the Pythagorean theorem to find the length of the shorter side.

Let w = length of the shorter side.

$w^{2} + 30^{2} = 34^{2} \\ w^{2} + 900 = 1156\\w^{2} = 256\\w = \sqrt{256} = 16$

The perimeter is 2l + 2w = 2(30) + 2(16) = 60 + 32 = 92 m

In a pile of coins there are 7 more quarters than nickels. If there is a total of$2.65 in coins, how many quarters are there?

Alinara [238K]

<span>A quarter is equivalent to 25 cents or $0.25 and a nickel is equal to 5 cents or $0.05. In the given in this item, if there are x nickels then, there are x + 7 quarters. With these and the total amount known, we can now compute for the value of x.
(x)(0.05) + (x + 7)(0.25) = 2.65
Simplifying,
0.05x + 0.25x + 1.75 = 2.65
Simplifying further,
0.3x = 0.9
The value of x from the equation is 3. Hence, there are 10 quarters.</span>
