A practice field is 350 feet long. The game field is 40% longer than the practice field. How long is the game field?
kifflom [539]

Answer: 490 feet

Step-by-step explanation: Since the game field is 40% longer than the practice field, it is 140% or 1.4 times the practice field. 350•1.4 is 490 feet.

Please help me!<br> Hint: the number is negative
wel

Answer:

-36 goes into the box

Step-by-step explanation:

Let the number be x,  then


(m^x)^{\frac{1}{3}}=m^{-12}


We now use the following property of exponents to simplify the left hand side of the equation.

(a^m)^n=a^{mn}

This implies that;

m^{x\times \frac{1}{3}}=m^{-12}


\Rightarrow m^{\frac{x}{3}}=m^{-12}


Since the bases are the same, we equate the exponents to get;


{\frac{x}{3}=-12


We now multiply both sides by 3 to get;


\frac{x}{3}\times 3=-12\times 3


\Rightarrow x =-36


Therefore the number that goes into the box is -36

Give the coordinates of Point P without using any new variables. <br><br> (Please show your work.)
poizon [28]

Answer:

(a-b, c)

Step-by-step explanation:

The midpoints of the two diagonals are the same, so we have ...

(P + (-a, 0))/2 = (O +(-b, c))/2

Multiplying by 2 and subtracting (-a, 0), we get ...

P = (0, 0) +(-b, c) -(-a, 0)

P = (a-b, c)

The ratio of the heights of two similar cylinders is 1:3. If the volume of the smaller cylinder is 67cm cubed, find the volume o
irina1246 [14]

Answer:

volume = 1809 cm³

Step-by-step explanation:

The ratio of the height of two similar cylinder is 1:3 . The volume of the smaller cylinder is 67 cm³. The volume of the larger cylinder can be computed below:

If 2 object are similar and the ratio of the corresponding sides is x ,then the ratio of their volume is x³.

ratio of height = 1/3

ratio of volume = (1/3)³ = 1/27

volume of smaller cylinder/volume of larger cylinder = 1/27 = 67/x

where

x = volume of the larger cylinder

x = 27 × 67

x = 1809  cm³

volume = 1809 cm³
