Please please Pleas answer this question please please

for every 4 miles Vanessa jogged, Cody jogged 3 miles. if Vanessa jogged 1 mile, how far would Cody have jogged

Ksju [112]

Alright here's the breakdown:

it said every 4 miles Vanessa jogged, Cody jogged 3 miles.

so

Vanessa jogged 1 mile

that means

Cody jogged .75 of a mile ( or 75% of 1 )

because

Cody will always jog 75% of how much Vanessa joged

so say that

Vanessa jogged 50 miles

all you do is take 75% of how much Vanessa jogged

and that should be how much Cody joged

hopes this helps!

A computer sells for $ 900 $900dollar sign, 900 and loses 30 % 30%30, percent of its value per year. Write a function that gives

Kazeer [188]

Answer:

The value of the computer is given by $900(0.7)^{t}$ .

Step-by-step explanation:

A computer sells for $900.

If the price of the computer loses 30% of its value per year, then it is compounded every year.

Now, the price of the computer t years after it is sold will be

$900(1 - \frac{30}{100})^{t} = 900(0.7)^{t}$ ........... (1)

Therefore, the value of the computer is given by the above equation (1). (Answer)

Classify each sequence as arithmetic, geometric or neither

Karolina [17]

Answer:

Geometric sequence = ⁵/9, ⁵/3, 5, 15, 45. . .

Arithmetic sequence = 16, 11, 6, 1, -4 . . .

Step-by-step explanation:

A geometric sequence is a sequence of numbers, in which every number in the sequence after the first term is multiplied by a common ratio, which gives us the next term. The common ratio is the ratio of a term to the term before it.

On the other hand, an arithmetic sequence is a sequence of number have a common difference between each consecutive terms. This common difference is gotten by subtracting a term from the term before it.

Now let's examine each sequence given:

==>16, 11, 6, 1, -4 . . .

11 - 16 = -5

6 - 11 = -5

1 - 6 = -5

-4 - 1 = -5

This is an arithmetic sequence. The commons difference "-5" is the same

==>⁵/9, ⁵/3, 5, 15, 45. . .

⁵/3 ÷ ⁵/9 = ⁵/3 × ⁹/5 = ⁹/3 = 3

5 ÷ ⁵/3 = ⁵ × ⅗ = 3

15 ÷ 5 = 3

45 ÷ 15 = 3

The common ratio "3" is the same. This is a geometric sequence.

2x3y − 3x2 + 7y2x − 12y written in standard form

AlekseyPX

Hey there,

Lets solve this equation step by step.

⇒ First of all, Simplify 2x×3y to 6xy

$6xy-3x^2+7y * 2x-12y$

⇒ Now Simplify 7y×2x to 14yx

$6xy-3x^2+14yx-12y$

⇒ Gather like terms

$(6xy+14xy)-3x2-12y
 
$

⇒ Simplify everything

$20xy-3x^2-12y$

Hence Simplified.

Two less than a number and five is 12 less than the number itself

Eva8 [605]

Answer: x - 2 + 5 = x - 12

Step-by-step explanation:

At first I was confused. Then I read the question again and translated it.

Less than translated means - 2.

A number, aka X.

and means plus(+).

when you put that together you get,

x - 2 + 5.

The next step is to translate to second part of the equation.

Is means equals(=).

So far we have: X - 2 + 5 = 12.

This is where I got confused...

After solving that peice, we have the words; " 12 less than the number it's self. I wasn't sure if 2 x's could be in the same equation. Now I know they can.

Above, we established that 'a number' is x.

Now, it's talking about that number again because it says; "The number itself." At first, I thought it was talking about 12 - 12! Then I realized that it's not.

The new equation, after understanding that in the second piece isn't 12 - 12, would be none other than,

x - 2 + 5 = 12 - x

I hope this helps!!
