Answer:
B. 21 and 19/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
21.76=21.761
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
21.761×100100=2176100
Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,
2176÷4100÷4=54425
Simplify the improper fraction,
=211925
In conclusion,
21.76=211925
Answer:
3.29 s
Step-by-step explanation:
We are given that
Height of building=240
Initial velocity=20ft/s
The height of the ball after t seconds is given by

When the ball strike the ground then
h(t)=0


Quadratic formula:

Using the quadratic formula




Time cannot be negative .Therefore,
t=3.29 s

Answer:
x is 12
Step-by-step explanation:
» From scalar properties:

Here is some pro tips, I take algebra 1, and I’m in middle school too.
x * x = x^2
If you see anything like (x + 5)(x - 5), solve using FOIL, (front, outer, inner, last), it’s basically the distributive property for four numbers and x’es.
Distributive property is a must know.
And also, if you are feeling nervous, remember, even if you fail the leap test, it doesn’t make you less of a intelligent, kind, and caring person.
