The ratio of the number of left-handed batters to the number of right handed batters is 5:8. There are 45 left-handed batters. f
Anuta_ua [19.1K]
Answer=15:39

Step1(find the number of right handed batters)

Left-handed batters=45

 5    45
__=___
8      x


Cross multiply
5x=360
divide both sides by 5
x=72
Right-handed batters=72

Step 2 (find the number of total batters)
total batters=45+72=117

Step3 (find the ratio of left handed batters to total batters)

Left-handed batters to total batters= 45/117
45/117 can be shortened to 15/39

Answer=15:39

the initial vertical velocity of a rocket shot straight up is 42 meters per second. How long does it take for the rocket to retu
Snowcat [4.5K]
It takes 4.3 seconds for the rocket to return to earth.

The equation is:
0=-9.8t^2+v_0t+h_0
where -9.8m/sec² is the acceleration due to gravity, v₀ is the initial velocity, and h₀ is the initial height.  We will go from the assumption that the rocket is launched from the ground, so h₀=0, and we are told that the initial velocity, v₀, is 42.  This gives us:

0=-9.8t^2+42t

We will use the quadratic formula to solve this.  The quadratic formula is:
x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Plugging in our information we have:
t=\frac{-42\pm \sqrt{42^2-4(-9.8)(0)}}{2(-9.8)}
\\
\\=\frac{-42\pm \sqrt{1764-0}}{-19.6}
\\
\\=\frac{-42\pm \sqrt{1764}}{-19.6}
\\
\\=\frac{-42\pm 42}{-19.6}=\frac{-42-42}{-19.6} \text{ or } \frac{-42+42}{-19.6}
\\
\\=\frac{-84}{-19.6}\text{ or }\frac{0}{-19.6}
\\
\\=4.3\text{ or }0

x=0 is when the rocket is launched; x=4.3 is when the rocket lands.

98 divided by 7


1. 98-round to 100
    7-round to 10

100 divided by 10=10

So 98 divided by 7 is about 10

That is one way
