NemiM [27]

Answer:

-3.33 ft. per second

Step-by-step explanation:

The rate of change of an object can be calculated by finding the difference in position between the starting point and end point, and then dividing by the difference in time between the starting time and end time. Using the values provided in the question we can calculate the following

$\frac{120ft - 70ft}{15s - 0s}$ = 3.33 ft. per second

With the calculation above we can see that the rate of change during these 15 seconds is 3.33 ft. per second. Since the endpoint is further down below ground level then we were descending which means that the rate of change would be a negative (-3.33 ft. per second)

On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is

baherus [9]

Answer:

$I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Step-by-step explanation:

Let I represent inches and F represent feet.

We have been given that on he scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is 16 feet.

We will use proportions to solve our given problem as:

$\frac{\text{Length on scale}}{\text{Actual length}}=\frac{6}{16}$

$\frac{I}{F}=\frac{6}{16}$

Now, let us solve for $I$ .

$I=\frac{6}{16}\cdot F$

$I=\frac{3}{8}\cdot F$

Now, let us solve our equation for F.

$I\cdot\frac{8}{3}=\frac{8}{3}\cdot\frac{3}{8}\cdot F$

$\frac{8}{3}\cdot I= F$

$F = \frac{8}{3}\cdot I$

Therefore, our required equations would be $I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

I AM IN DESPERATE NED OF QUICK HELP PLEASEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!

rosijanka [135]

Answer:

Step-by-step explanation:

To solve this equation, we need the formula for perfect squares:

$(a + b)^2 = a^2 + 2ab + b^2$

$(a - b)^2 = a^2 - 2ab + b^2$ <em>this is the formula we will use because the signs match the one in the question</em>.

Knowing these, we can set up an equation that assumes that the answer we will end up with is a perfect square.

Work:

$(v - x)^2 = v^2 -8v + x^2$

this is the setup for being able to solve for the unknown $x$ , now we need to solve for $x$ .

$(v - x)^2 = v^2 - 8v + x^2$ (I replaced $2ab$ with $8v$ because I'm setting up this question to be a perfect square).

$(v - x) (v - x) = v^2 - 8v + x^2$

multiply the left side. Remember that your answer will not be $v^2 + x^2$ , but $v^2 - 2vx +x^2$ .

$v^2 - 2vx + x^2 = v^2 + 8v + x^2$

Divide like terms and isolate the variable. In this case, $v^2$ and $x^2$ are on both sides, so dive them and they will be canceled out.

$2vx = 8v$

divide by $2v$ and you will have your value for $x$ .

$x = 4$

Now we plug $x$ into our original equation equation for perfect squares.

$(v - 4)^2 = v^2 - 8v + 16$

Our final answer is 16.

What is the total length of the tadpoles that are 1/8 inch and 1/4 inch long?

m_a_m_a [10]

Answer: 7/8 inches

Step-by-step explanation: There are 3 x's for 1/8 so that is 3/8. There are 2 x's for 1/4 which is 2/4, but you need to have the same denominator so you do 2 times the numerator and denimator which is 4/8. 3/8 + 4/8 = 7/8
