A park is in the shape of a rectangle. The park authorities are planning to build a 2-meter-wide jogging path in the park (shown

Burka [1]

First, we need to find the area of the two rectangles in this picture. We know that area = l*w.

So for the larger rectangle, we know the l = 100 m, and the w = 60 m. Let us find the area:

$A=100*60=6000 m^{2}$

So the larger rectangle area is 6000 m.

The smaller rectangle has dimensions that are 2 m less on every side. So we can recalculate these dimensions as l = 96 m and w = 56 m.

Let's find the area of the smaller rectangle:

$A=96*56=5,376 m^{2}$

So we know that the area of the smaller rectangle is 5,376 m.

The area of the jogging path is going to be the difference between these two rectangles. Let us solve:

$6,000-5,376=624 m^{2}$

So now we know that the area of the jogging path is $624 m^{2}$ .

PLEASE help with these questions??<br> there are 7 of them!<br> Thank you!!

svetlana [45]

We know in these kind of triangles that have a 90 degrees angle, we can do:

${a}^{2} + {b}^{2} = {c}^{2}$

so the first question:

$\sqrt{ {99}^{2} + {20}^{2} } = 101$

and then:

$b = \sqrt{ {17}^{2} - {15}^{2} } = 8$

so , when you want to rationalize , usually you must multiply the irrational factor as 1:

$\frac{ \sqrt{15} }{ \sqrt{15} } = 1$

so , now multiply:

$\frac{3}{ \sqrt{15} } \times \frac{ \sqrt{15} }{ \sqrt{15} } = \frac{3 \sqrt{15} }{15} = \frac{ \sqrt{15} }{5}$

in the next question,we know negative numbers in radical don't have any solution so 2 is correct,

Izzo's Pizza sells four types of pizza crust. Last week, the owner tracked the number sold of each type, and this is what he fou

11111nata11111 [884]

Answer:

797

Step-by-step explanation:

First, we need to find the number of pizzas sold last week by finding the sum of the pizzas sold:

307 + 224 + 161 + 191 = 883

Next, we need to find the proportion of stuffed crust and pan style pizzas sold last week by adding the number of both sold and dividing by the total number of pizzas sold:

(191+161) / 883 = 352 / 883

Now we need to multiply this proportion by 2000 to find the expected number of stuffed crust or pan style pizzas:

(352 / 883) * 2000 = 797.28 = 797

Find the Area of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place

mart [117]

Step-by-step explanation:

Area of Figure

= Area of Parallelogram + Area of Semicircle

= (26)(13) + 0.5π(24/2)²

= 338 + 72π

= 564.2.
