Answer:

The total area for all 16 hamburgers is <u>113.04 in²</u>.

Step-by-step explanation:

Given:

Chris made hamburgers for his family and they each had a diameter of 3 in.

If he made 16 hamburgers.

Now, to find the total area for all 16 hamburgers.

So, the diameter 3 in is given and we need first to find the radius:

Radius\ (r)=\frac{Diameter}{2} =\frac{3}{2} =1.5\ in.

Now, to get the area of a hamburger we put formula:

<u><em>(Taking the value of π = 3.14.)</em></u>

Area=\pi r^2\\\\Area=3.14\times (1.5)^2\\\\Area=3.14\times 2.25\\\\Area=7.065\ in^2.

Now. to get the total area of 16 hamburgers by multiplying 16 by the area of a hamburger:

7.065\times 16\\\\=113.04\ in^2.

Therefore, the total area for all 16 hamburgers is 113.04 in².

Phyllis invested 51000 dollars, a portion earning a simple interest rate of 4 percent per year and the rest earning a rate of 7
Liono4ka [1.6K]

Answer:

Phyllis invested $11,000 at a simple interest rate of 7 percent per year and $40,000 at a simple interest rate of 4 percent per year.

Step-by-step explanation:

From the information provided, you can write the following equations:

x+y=51000 (1)

0.04x+0.07y=2370 (2), where

x is the portion earning a simple interest rate of 4 percent per year

y is the portion earning a simple interest rate of 7 percent per year

First, you can isolate x in (1):

x=51000-y (3)

Now, you can replace (3) in (2) and solve for y:

0.04(51000-y)+0.07y=2370

2040-0.04y+0.07y=2370

0.03y=330

y=330/0.03

y=11000

Then, you can replace the value of y in (3) to find the value of x:

x=51000-11000

x=40000

According to this, the answer is that Phyllis invested $11,000 at a simple interest rate of 7 percent per year and $40,000 at a simple interest rate of 4 percent per year.

stiv31 [10]

Answer:

<u>True</u>

Step-by-step explanation:

A Kilogram (kilo) is a unit of measuring metric mass. To perform this conversion you need to note that

1 Kilogram (kg) = 1000 grams

Which means that <em>converting Kilogram to Grams </em>would involve multiplying kilogram by 1000.

For example,  100 kg to grams = 100 * 1000 = 100,000 Grams
