To be able to determine what fraction of a day is 45 minutes, let's first determine how many minutes are there in a day.
1 day
Step-by-step explanation:
3, 2
2.5
2.25
Answer:
$100
Step-by-step explanation:
First add up how much she spent
$115+75= $190
Then Subtract from how much she had to spend
$290-190= $100
hope this helps:)
Answer:
x=12
Isosceles triangle
Step-by-step explanation:
The lines on the sides means that the two sides are equal. Two equal sides means that it is an isosceles triangle. The angles at the base must be equal
35 = x+12
Subtract 12 from each side
35-12 = x+12-12
23 = x
According to the direct inspection, we conclude that the best approximation of the two solutions to the system of <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)
<h3>What is the solution of a nonlinear system formed by two quadratic equations?</h3>
Herein we have two parabolae, that is, polynomials of the form a · x² + b · x + c, that pass through each other twice according to the image attached to this question. We need to estimate the location of the points by visual inspection on the <em>Cartesian</em> plane.
According to the direct inspection, we conclude that the best approximation of the two solutions, that is, the point where the two parabolae intercepts each other, to the system of two <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)
