Answer:
D - No, the ordered pair (4,9) is a solution to this problem.
Step-by-step explanation:
If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)
In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;
(2, 4.5)
(3, 6.75)
(4, 9)
So that is why the ordered pair of (4,9) would be a solution to this problem.
Hope that makes sense!
Answer:
x = 135°
Step-by-step explanation:
The angle x is the same fraction of 360° that the shaded area is of the area of the circle.
The area of a circle is given by the formula ...
A = πr²
For a radius of 12 cm, the area of the circle is ...
A = π(12 cm)² = 144π cm²
Then the measure of angle x is ...
x = (54π cm²)/(144π cm²)×360°
x = 135°
The answer is 7 ^39 in the field.
Please correct me if I'm wrong!! :)
Dividing by 100 is the same as multiplying by 1/100 or 0.01, because when you divide by a fraction, in this case 100/1, you actually multiply by the reciprocal, which would be 1/100. For example 4/100 = 4 x 1/100 = 4/100 = 1/25 = 0.04.
You can also just move the decimal two place values to the left to divide by 100. For example, 4/100 = 4. /100 = 0.04 = 1/25
