A = 2w+5

example: on week three, she would have the recipes from the other weeks that you have to account for as well as the extra five

2(3)+5=11 so A would equal 11 by week three.

Use multiplication because it is essentially repeated addition.

2(from week 1) + 2(from week 2) + 2(from week 3) + 5(prior to school) =11

We looking for distance

drek231 [11]

Answer:

240 m

Step-by-step explanation:

Figure is attached.

The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min. The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).

What's the area under the graph?

The red outline forms a trapezoid. The area of a trapezoid is $A=\frac{1}{2}h(b_1+b_2)$ where the <em>b</em>'s are the lengths of the two parallel base and <em>h</em> is the height (the distance between the bases).

Reading the graph carefully (notice the scales!)...

$A=\frac{1}{2}(4)(30+90)=(2)(120)=240 \text{m}$

PLEASE HELPPPPPP FINDING CIRCUMFERENCE AND AREA OF A CIRCLE

11111nata11111 [884]

Answer:

The circumference of the circle is 28.26 m.

The area of the circle is 63.585 $m^{2}$ .

Step-by-step explanation:

To solve for the circumference of the circle, start by using the circumference formula of a circle, which is $C= 2\pi r$ . However, 3.14 will be used instead of $(\pi)$ for this formula.

First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.

Next, plug in the radius into the formula, and the formula will look like $C=(2)(\pi )(4.5 m)$ . Then, solve the equation, and the answer will be 28.26 m.

To solve for the area of the circle, start by using the area formula of a circle, which is $A=\pi r^{2}$ . However, 3.14 will be used instead of $(\pi)$ for this formula.

For the area, plug the radius into the formula, and the formula will look like $A= (3.14)(4.5m)^{2}$ . Then, solve the equation, and the answer will be 63.585 $m^{2}$ .
