Answer:

3 photo frames

Step-by-step explanation:

1 frame uses 1/4 meters. You can solve this as a proportion. 1 is to 1/4 and x is to 3/4. 1/4 x 3 is 3/4. So multiply 3 x 1 as well. You get 3.

Hope it helps!

Projectile Is shot upward from the surface of Earth with an initial velocity of 136 meters per second. Use the position

Anna007 [38]

Answer:

$v(3\,s) = 106.6\,\frac{ft}{s}$ , $v(15\,s) = -11\,\frac{ft}{s}$

Step-by-step explanation:

The velocity function of the projectile is obtained by deriving the position function:

$v(t) = -9.8\cdot t + 136$

Now, the velocities after 3 and 15 seconds are, respectively:

$v(3\,s) = -9.8\cdot (3) + 136$

$v(3\,s) = 106.6\,\frac{ft}{s}$

$v(15\,s) = -9.8\cdot (15) + 136$

$v(15\,s) = -11\,\frac{ft}{s}$

A wooden board 100 centimeters long is cut into two pieces. One piece is 16 centimeters longer than the other. What are the leng

Bezzdna [24]

x = the length of one piece

y = the length of the other piece

the total length is 100 cm this means

x + y = 100

one piece is 16 inches longer than the other

first we need to convert inches to cm:

1 in = 2.54 cm

16 in = 2.54*16 = 40.64

now we can write

x = y + 40.64

by solving the system of equations

x + y = 100

x = y + 40.64

we find

x = 70.32 cm

y = 29.68 cm

the lengths of the two pieces are 70.32 cm and 29.68 cm.
