Mathematics

e-lub [12.9K]3 years ago
5 0

Answer:

4 44/49

Step-by-step explanation:

7 7/9 is 70/9

then u use 70/9 multiply by 7/4(I call it keep, change, flip method for division of fraction)

You keep the 1st fraction and because it is a mixed fraction, changing it to improper fraction is easier to solve it later on.

after that, you change the division sign to multiply sign(÷ to ×)

then you flip the 2nd fraction, which means 7/4 becomes 4/7

So overall it becomes 60/7 × 4/7 =240/49,4 44/49 as a mixed fraction.

Answer is 4 44/49

Andre45 [30]

Answer:

  20 ft

Step-by-step explanation:

The formula for the surface area of a pyramid is often written in terms of the base dimensions and the slant height. We can solve that formula for the slant height.

  SA = base area + lateral area

  SA = b² + 2bs . . . . . where b is the base dimension, and s is the slant height

  SA -b² = 2bs . . . . . subtract the base area

  s = (SA -b²)/(2b) . . . . divide by the coefficient of s

Using the given values for surface area and base length, we find ...

  s = (896 -16²)/(2·16) = 640/32 = 20 . . . feet

The slant height of the pyramid is 20 feet.

Lana71 [14]
Set s(t) = 0 which means it hits the ground.  The formula doesn't fit the parameters given as it shows that the pitcher is standing on something 37 feet high.
<span>s(t)=-16t^2+140t+37 and has an initial velocity of 140.
Graphing or solving this, t= 9 seconds when it hits the ground.
The velocity V(t) is the derivative of s(t)
V(t) = -32t+140
V(9) = -148 ft/second which is going down

Umnica [9.8K]

Answer:

The answer is t\geq 20.

Step-by-step explanation:

To solve the inequality, start by solving for the variable t.

To solve for the variable t, subtract 3.5t from both sides. The inequality will look like 6.5t\geq 130.

Then, divide both sides by 6.5 in order to get the variable t by itself. The inequality answer will look like t\geq  20.
