Answer: From my math I got 145 so I hope that's right
Step-by-step explanation:
100%/x%=4.6/6.67
(100/x)*x=(4.6/6.67)*x - we multiply both sides of the equation by x
100=0.689655172414*x - we divide both sides of the equation by (0.689655172414) to get x
100/0.689655172414=x
145=x
x=145
7300 tons<span>, or </span><span>7.3 million kilograms</span>
Percent means parts out of 100
65%=65/100=0.65
'of' mens multiply
'is' means equals or '='
65% of what number is 26
0.65 times what=26
divide both sides by 0.65
0.65/0.65 what=26/0.65
1 what=40
what=40

Answer:
x1=2 and x2 =-3/2
Step-by-step explanation:
2x^2-x-6=0 (quvadratic equation)
a=2, b=-1, c=-6
x1=(-b+sqrt(b^2-4ac))/2a
x1=(-(-1)+sqrt((-1)^2 - 4*2*(-6)))/2*2
x1 =(1+sqrt (1+48))/4
x1= (1+sqrt(49))/4
x1 =(1+7)/4
x1=8/4
x1=2
x2=(-b-sqrt(b^2-4ac))/2a
x2=(1-7)/4
x2=-6/4
x2=-3/2
A right triangle has a perpendicular corner in it. This means that one of its angle has a measure of 90 degrees. The sum of all angles in the triangle is 180. To determine the acute angle, or more importantly, the last missing angle, it would be,
180 = 90 + 63.7 + x
x = 180 - 90 - 63.7
x = 26.3 degrees
This is an acute angle because it is less than 90. So, the answer is 26.3 degrees.
