10:18 and 15:27 because whenyou mutiply the numerator and denominatorby any number the answer would be equivalent to 5/9
Answer:
It's 40
Step-by-step explanation:
Arithmetic Sequence.
Common Difference:
160−163=−3
157−160=−3
d=−3
Explicit Formula:
an=a1+(n−1)d
a42=163+(41)(−3)
a42 = 40
Answer:
$1.98
Step-by-step explanation:
1.65/5=0.33
1.65+0.33=1.98
check: 1.98/6 =0.33
0.33x5=1.65
<h3>
Answer: x*a^2 or a^2*x</h3>
======================================
Work Shown:
a^(b+2) = a^b*a^2 ... break up the exponent
a^(b+2) = x*a^2 ... replace a^b with x
We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.
Answer: 1100 boys
Step-by-step explanation:
45% students are girls
45% girls in number = 900
1% be = 900x45= 20
55% students are boys
55% boys in number= 55x20= 1100 boys
