Answer:

675 ft^2

Step-by-step explanation:

The radius is 15, so replace r in the formula with 15

A=\pi 15^2

A = 225 pi

A = 675

(using 3 for pi, since they specified)

Answer:

19.2 kg

Step-by-step explanation:

Amount of Bananas consumed in US per year = 5.77 million metric tons

Since 1 million = 10^{6} and 1 metric ton = 1000 kg, we can write:

Amount of Bananas consumed in US per year = 5.77 \times 10^{6} metric tons

Amount of Bananas consumed in US per year = 5.77 \times 10^{6} \times 1000 = 5.77 \times 10^{9} kg

Number of people in US = 301 million = 301 \times 10^{6}= 3.01 \times 10^{8}

We have to find how many kilograms of bananas are consumed per person in 1 year in US. For this we have to divide the total amount of bananas eaten in US per year with total number of people in US, which will be:

\frac{5.77 \times 10^{9}}{3.01 \times 10^{8}} \\\\ = 19.2

This means, 19.2 kilograms of bananas are eaten in US per person in a year.

LOTS OF POINTS!?!?!?Write a linear function f with the values f(5)=−1 and f(0)=−1.<br> f(x)=
Brut [27]

Answer:

The euation of the linear function is:

  • y = -1

Step-by-step explanation:

As the function has the values

  • at x = 5, f(5) = -1
  • at x = 0, f(0) = -1

Thus, the two points are:

  • (5, -1)
  • (0, -1)

Finding the slope between (5, -1) and (0, -1)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)

m=\frac{-1-\left(-1\right)}{0-5}

m=0

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.

so at x = 0, y = -1

Thus, the y-intercept 'b' = -1

Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation

y = mx+b

y = 0x + -1

y = -1

Therefore, the euation of the linear function is:

  • y = -1

B. If some amount of water contains 1400 oxygen atoms, how many hydrogen atoms does it contain?
Genrish500 [490]

Answer:

B: 2800 hydrogen atoms

C: 6760 hydrogen atoms

D: y=amount of oxygen atoms*2

Step-by-step explanation:

B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.

C: Same thing as B. 3380*2=6760

D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

WILL GIVE BRANLIEST!!! Pls help! Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the
iren [92.7K]

Let , coordinate of points are P( h,k ).

Also , k = 3h + 1

Distance of P from origin :

d=\sqrt{h^2+k^2}

Distance of P from ( -3, 4 ) :

d=\sqrt{(h+3)^2+(k-4)^2}

Now , these distance are equal :

h^2+(3h+1)^2=(h+3)^2+(3h+1-4)^2\\\\h^2+(3h+1)^2=(h+3)^2+(3h-3)^2

Solving above equation , we get :

P=(\dfrac{16}{21},\dfrac{23}{7})

Hence , this is the required solution.
