Kobe has collected 750 football cards and 660 baseball cards. He wants to divide them into piles so that each pile has only one

Harrizon [31]

Answer: 30 cards

Step-by-step explanation:

To find the greatest possible number of cards in each pile such that there is the same number of cards in each pile we need to find the greatest common factor of 750 and 660.

Using Euclid division method , we have

$750=1(660)+90\\\\660=7(90)+30\\\\90=3(30)+0$

Hence, the greatest common factor of 750 and 660 = 30

Thus, there will be 30 cards in each pile.

A golfer takes a swing from a hill twenty feet above the cup with an initial upwards velocity of 76 feet per second. How long do

jeka94

Answer:

t = 5 seconds

Step-by-step explanation:

A golfer takes a swing from a hill twenty feet above the cup with an initial upwards velocity of 76 feet per second.

We need to find how long does it take the ball to land on the ground near the cup.

The equation for the path of the ball is given using second equation of kinematics as follows :

$-16t^2+76 t+20=0\\\\\text{or}\\\\-4t^2+19t+5=0\\\\-4t^2+20t-t+5=\\\\-4t(t-5)-1(t-5)=0\\\\(t-5)(-4t-1)=0\\\\t=5, t=\dfrac{-1}{4}\ s$

Neglecting negative value,

It will take 5 seconds for the ball to land on the ground near the cup.

May somebody help me? I’m just tryna catch up because this assignment is a deadline

Elina [12.6K]

Answer:

$\sqrt{\frac{36}{169} } = \frac{6}{13}$

Step-by-step explanation:

First, transform the fraction inside the square root into the following:

$\frac{\sqrt{36}}{\sqrt{169}}$ .

Next, you can take the square root of 36 ( $\sqrt{36}$ ), which is 6 ( $6^{2} = 36$ ).

$\frac{\sqrt{36}}{139} = \frac{6}{\sqrt{169}}$

Then, you can take the square root of 169 ( $\sqrt{169}$ ), which is 13 ( $13^{2} = 169$ )

$\frac{6}{\sqrt{169}} = \frac{6}{13}$

michelle and rosa are researching the deepest lakes in the united states for a school project. lake tahoe has a depth of 1,644 f

Hatshy [7]

Answer:

Rosa is closer to the correct depth.

Step-by-step explanation:

To show that two measurements are nearly equivalent, we must convert one of the measurements to the other unit.

1 m = 3.281 ft

$\text{Depth } = \text{1644 ft} \times \dfrac{\text{1 m}}{\text{3.281 ft}} = \textbf{501.1 m}$

Neither is correct but Rosa is closer to the correct depth.
