Answer:

  • There are 10 bags.
  • 9 of the bags have real coins, 1 bag has fakes.
  • A real coin weighs 10 g, a fake coin weighs 9 g.

Take 1 coin from the first bag, 2 coins from the 2nd bag, 3 coins from the 3rd bag, 4 coins......., 5 coins............,  .........10 coins.......

If there are no fakes at all, the total weight should be: 550 grams.

If the weight is 545 grams, there would be 5 fakes, and so the fake bag would be Bag 5. (because there is a 5 gram difference)

I hope this helps!

kieth has 8 1/2 cups of flour. he uses 5 2/3 cups to make muffins. how many cups of flour does keith have left?
Marta_Voda [28]
Hi there!

First, we need to make the denominators of the fractions the same. This can be done by multiplying 1/2 by 3/3 and 2/3 by 2/2. This gives us the fraction 3/6 and 4/6. We can subtract 4/6 from 3/6 to get -1/6, which will need to be taken out of the fraction later. Lastly, we will subtract 8-5 to get 3, of which we also need to subtract 1/6 from that. Therefore, Keith has 2 5/6 cups of flour left.

Hope this helps!! :)

Answer:

x = 35 feet.

Step-by-step explanation:

Given that,

The height of the person is 5 feet.

The height of the flag and the eye is (x-5) feet.

We can calculate using trigonometry.

\tan\theta=\dfrac{(x-5)}{30}\\\\\tan(45)=\dfrac{(x-5)}{30}\\\\(x-5)=30\\\\x=30+5\\\\x=35\ ft

So, the value of x is equal to 35 feet. The correct option is (c).

What is the volume of the rectangular prism in cubic yards?​
strojnjashka [21]

The volume of the rectangular prism is 1120 yd³.

<h3>What is a prism?</h3>

A prism is a solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

To calculate the volume of the rectangular prism, we use the formula below.

Formula:

  • V = LWH.......... Equation 1

Where:

  • V = Volume of the rectangular prism
  • L = Length of the prism
  • W = Width of the prism
  • H = Height of the prism.

From the question,

Given:

  • L = 14 yards
  • W = 8 yards
  • H = 10 yards.

Substitute thee values into equation 1

  • V = 14×8×10
  • V = 1120 yd³

Hence, The volume of the rectangular prism is 1120 yd³.

arlik [135]

Answer:

Brett's statement is true

Step-by-step explanation:

A negative times a negative will always equal a positive number.

If you see two negative numbers being multiplied together, you can ignore the negative signs and treat them both like positive numbers.

-4 x -5 = 20

4 x 5 = 20
