Ok... we'll do the same here, elimination
g = carbs in one glass of milk
b = carbs in a snack bar
in this, we can simply multiply by -2 at the bottom to get a -4g, and thus "eliminate" the g-variable
Answer:
25%
Step-by-step explanation:
when we count, we know that there are 8 possible outcomes as to where the spinner will land.
<em>{the following will be assuming each section has an equal chance of being landed on; that the spinner is not weighted}</em>
<em />
We know that two of these 8 possibilities are "A"
This means that A has a 2/8 chance of being landed on
we can simplify 2/8 to 1/4; because they are equivalent ratios/fractions
to calculate percentage, we can follow through with our equation of 1/4
[divide 1 by 4]
1 / 4 = 0.25
We multiply this number by 100 to find percentage,
0.25 × 100 = 25
meaning that A has a 25% chance of being spun
hope this helps!! have a lovely day :)
Right isosceles triangle <3
Its a right triangle, and the two sides are equal so its isosceles
Dividing by a fraction is equivalent to multiply by its reciprocal, then:
Now, we need to express the quadratic polynomials using their roots, as follows:
where y1 and y2 are the roots.
Applying the quadratic formula to the first polynomial:
Applying the quadratic formula to the second polynomial:
Applying the quadratic formula to the third polynomial:
Applying the quadratic formula to the fourth polynomial:
Substituting into the rational expression and simplifying:
