The thickness of a quarter is approximately 2 millimeters. How many quarters would you need to make a two kilometer high pile? a

Romashka-Z-Leto [24]

We need 1,000,000 quaters to make a two kilometer pile

Solution:

The thickness of a quarter is approximately 2 millimeters

We need to find the quarters needed to make two kilometer high pile

Let us first convert 2 km to millimeters

Use the conversion factor

1 kilometer = 1000000 millimeters

Therefore,

2 kilometer = 2 x 1000000 = 2000000 millimeters

We need 2,000,000 mm to make a 2 km pile

Given that, Each quarter is 2 millimeters thick

thickness of quarter = 2 millimeters

Divide the total milimetres by the thickness of a quarter

$\rightarrow \frac{2000000}{2} = 1000000$

Thus we need 1,000,000 quaters to make a two kilometer pile

A 3 ounce serving of tuna provides 21 grams of protein. Use equivalent ratios to find how many grams of protein are in 9 ounces

denis-greek [22]

Answer:

There would be 63 grams of protein in 9 ounces of tuna.

Step-by-step explanation:

Equivalent ratios compare two different quantities the have the same rate regardless of the amount. In this example, for every 3 ounces of tuna, there are 21 grams of protein. We can write this as a ratio of: 3/21. Like fractions, we can simplify ratios by dividing the numerator and denominator by the same greatest common factor. In this case, we would divide both the numerator and denominator by 3: (3÷3)/(21÷3) = 1/7. So, our new ratio is for every ounce of tuna, we have 7 grams of protein. Using equivalent ratios, we can set up our ratios to solve for the grams of protein in 9 ounces of tuna: 1/7 = 9/x. Since we have to multiply both the numerator and denominator by the same factor, in this case 9, then our x = 63 grams of protein.

A right triangle is drawn on a coordinate plane. Two vertices of the triangle are points A(−2,4) and B(3,−2) . The third vertex

SVEN [57.7K]

As you can see in the image, point C must be (-2, -2), because it is the only point that will create a right triangle that is in the third quadrant.

To find the distance between point A and point C, just subtract the y-values.

$\sf 4-(-2)=\boxed{\sf 6}$
