Rosa can run 4 miles in 56 minutes.How many miles does rosa run if she runs 42 minutes?

2 answers:

6 0

Rosa runs 3 miles in 42 minutes.

I divided 42 by 56 to get the percentage that will be multiplied to 4 miles to get the number of miles Rosa runs in 42 minutes.

42 / 56 = 0.75 * 100% = 75%

75% * 4 miles = 3 miles.

3 miles within 42 minutes

A bean plant grows at a constant rate for a month. After 10 days, the plant is

777dan777 [17]

Answer:

B. y - 35 = 2(x - 10)

Step-by-step explanation:

The height of the plant, y, after x days could be modeled by the equation

<h3>y-y0=k(x-xo) (1),</h3><h3>where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.</h3><h3>From equation (1), k could be evaluated as follows:</h3><h3>k=(y-y0)/(x-x0) </h3><h3>From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.</h3><h3>Thus,</h3><h3>k=(55-35)/(20-10)=2</h3><h3>Therefore, the model equation becomes</h3><h3>y-35=2(x-10)</h3><h3></h3>

HELP I'M SOOOOOO ANGRYYYYY PLEASE HELPPPP<br>determine the values of X for which g(x) is defined

tiny-mole [99]

Answer: Any real number x as long as $x \ne 0$ and $x \ne -\frac{2}{3}$

In other words, anything but 0 or -2/3 is valid.

========================================================

Explanation:

Set the denominator equal to zero and solve for x

2(3x^2 + 2x) = 0

3x^2 + 2x = 0

x(3x + 2) = 0

x = 0 or 3x+2 = 0 .... zero product property

x = 0 or 3x = -2

x = 0 or x = -2/3

If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x) will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.

Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.

.A square field has a side 30m. Find the cost of fencing its four sides at Rs. 10 per metre

Ratling [72]

Answer:

1,200

Step-by-step explanation:

So first we need to find the perimeter

$P=30+30+30+30\\\\P=120$

so it costs 10 per meter

$120\times 10=1,200$
