4 * 16 = 64, or 4 * 15 = 20.
Hope that hepls.
Answer:
Step-by-step explanation:
To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that
Substituting a,b,c and d for 8,15,2 and 13 we obtain that
Answer:
m∠A + m∠B = 155
Step-by-step explanation:
ABC is an isosceles triangle that has a 130° angle at vertex B
then
m∠A = (180 - 130)/2 = 50/2 = 25 = m∠C
then
m∠A = m∠C = 25°
Answer:
B) {x| x<-12 or x>-6}
Step-by-step explanation:
-2/3x>8
change -2/3 as -3/2 and multiply both sides by -3/2x
-2/3x•(-2/3)x<-3/2•8
calculate
reduce
x<-3•4
multiply numbers
-----------
x<-12
-----------
now we're done with the first equation, let's do the other equation to find the answer!
-2/3x<4
multiply both sides by -3/2 and again change -2/3 by -3/2
-3/2•(-2/3)x>-3/2•4
calculate
reduce
x>-3•2
multiply numbers
----------
x>-6

Answer:0.27
Step-by-step explanation:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
4 / 15 = 0.266
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 266
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule II applies, so 4/15 (or 0.266) rounded to the nearest hundredth in decimal format is:
0.27
