Answer:
Step-by-step explanation:
so... 60% of his entire book is 114 pages...
let x represent his entire book
turn ur percent to a decimal
" of " means multiply and " is means equals
0.60x = 114...divide both sides by 0.60
x = 114/ 0.60
x = 190 pages left <===
There are 2000 pounds in a ton - so the rino weighs 3.75 x 2000 = 7500 pounds
a percentage can be converted to a decimal - if you want to know what 3.8% of a number is, move the decimal two spaces to the left 3.8% is 0.038 -
Multiply 7500 pounds by 0.038 - the answer is 285 pounds.
3.4+0.5y +1.1=-4.5
3.4+1.1+0.5y= -4.5
4.5+0.5y=-4.5
move 4.5 to the other side
sign changes from +4.5 to -4.5
4.5-4.5+0.5y= -4.5-4.5
0.5y= -4.5-4.5
0.5y=-9
divide both sides by 0.5
0.5y/0.5= -9/0.5
Answer: y= -18
<span>Standard deviation is the square root of variance. Variance is always a non-negative number, since you can't take the square root of a negative number. So neither can be negative </span>
Answer:
7/6
Step-by-step explanation:
the original line has a slope of -6/7, so the line perpendicular is 7/6. we swap the numerator and denominator, and if the starting slope is positive, the perpendicular slope would be negative, and the other way around.
