Answer:

First table

Step-by-step explanation:

The first table shows the relationship y=1/7x

The second table doesn't show a relationship due to (6,15)

The third table doesn't show a relationship due to (3,5)

The fourth table doesn't show a relationship due to (2,10)

What does this graph tell you about the growth of the Corn stock
ladessa [460]
The question is very vague, but here's what it tells me.
We know that the coordinates are (4, 25) meaning the x is 4 and the y is 25.
Since time is x and height is y, all this is saying is this:
After 4 weeks, the corn stock is 25 inches.

You can go deeper and divide 25 by 4 to find out the rate of growth. That would give you 6.25, meaning
The corn stock grows 6.25 inches every week.

Find the volume of the cone shown below.
BlackZzzverrR [31]

Answer:

D

Step-by-step explanation:

The formula for volume of cone is  V=\frac{1}{3}\pi r^2 h

Where

V is the volume

r is the radius of the circular base

h is the height of the cone

<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>

<em>V=\frac{1}{3}\pi (9)^2(12)\\=324 \pi</em>

<em />

<em>correct answer is D</em>

75 miles to 225 miles as a fraction in simplest form
Pie

Answer:

\frac{1}{3}

Step-by-step explanation:

When reducing a number to its lowest term you use the GCF of the denominator and numerator then divide using this number. :

\frac{75}{225} ÷\frac{75}{75} = \frac{1}{3}

The gcf of 75 and 225 is 75 so we divide both the numerator and denominator by 75.

Dylan is rollerblading along an 8 mile trail in the forest park she stopped for water after 2.4 miles. After another 3.1 miles,
mr_godi [17]

Add up the amount of miles she actually reached to

2.4 + 3.1 =

5.5 = miles already traveled

And then subtract it from the 8 mile trail

8 - 5.5 =

2.5 miles

About 2.5 or 3 miles (rounded to the tenth or whole number?)

Solve the equation 2x^2 + 16x + 21 = 0 to the nearest tenth.
Crank

Answer:

Rounded to the nearest tenth the solutions to the equation are:

x = -1.7   and x = -6.3

Step-by-step explanation:

Since this is a quadratic equation of the form:

ax^2+bx+c=0

Use the quadratic formula, which tells you that the solutions would be given by:

x=\frac{-b+-\sqrt{b^2-4ac} }{2a}

So in our case, the quadratic formula gives:

x=\frac{-b+-\sqrt{b^2-4ac} }{2a}\\x=\frac{-16+-\sqrt{16^2-4(2)(21)} }{2*2}\\x=\frac{-16+-\sqrt{88} }{4}

which gives us two real solutions:

x = - 1.654792

x = -6.345207

Which rounded to the nearest tenth give:

x = -1.7   and x = -6.3
