Answer:
120 students are predicted to like chocolate chip ice cream best.
Step-by-step explanation:
40% = 0.4
Multiply 300 by 0.4 to get 40% of 300.
300 × 0.4 = 120
Answer:
He saw <u>1 duck</u> and <u>3 dogs</u>.
Step-by-step explanation:
Given:
Evan went to the park and saw four animals.
Each animal was either a duck or a dog.
He saw a total of 14 legs.
Now, to find the number of each animal he had seen.
Let the number of duck be
And the number of dog be
So, total number of animals:
Now, the total number of legs he did see:
<em>As we know the legs of a duck are 2 and a dog are 4.</em>
Adding both sides by -16 we get:
Dividing both sides by -2 we get:
The number of duck = 1.
Now, putting the value of in above equation we get:
The number of dogs = 3.
Therefore, he saw 1 duck and 3 dogs.
An increase in miles driven, increases the total charge, by the rate
multiplied by the distance in miles.
<h3>The correct responses;</h3>
- The equation that represents the situation is; <u>y = 2.2·x + 2.5</u>
- <u>The y-intercept represents the flat fee</u>
<h3>Method by which the above equation is arrived at:</h3>
The amount the Yellow Cab Company charges for pick up = $2.50
Amount the cab company charges per mile = $2.20
The equation that represents the situation is;
- Total charge, <u>y = 2.2·x + 2.5</u>
Where;
x = The number of miles driven
<h3>Details on the y-intercept's meaning;</h3>
The above equation is in the form of the equation of a straight line in slope and intercept form, y = m·x + c
Where;
m = The slope
c = The y-intercept
The y-intercept is the y-value when <em>x</em> = 0
- At x = 0, the y-intercept is; y = 2.2 × 0 + 2.5 = 2.5
Therefore;
- <u>The y-intercept represent the flat fee for picking someone up</u>.
