Answer:   5 5/16 inches

Step-by-step explanation:

3 ways to get this.

1. Estimate. You know that 8 × 5 is 40, and 40 is close to 42.  40 ÷ 8 is  5

There is only one answer close to that so choose A.

2. Calculate. Change the numbers to a decimal and divide:  42.5 ÷ 8 = 5.3125

3 . Fraction multiplication and division: Make 42 1/2 into an "improper fraction"

and multiply.   85/2 × 1/8 = 85/16   Divide  "old style" long division to get a remainder.  85 ÷ 16 = 5, remainder 5.  Put the remainder 5 over the divisor 16 to end up with 5 5/16

serious [3.7K]

Answer:

-12\frac{81}{200}

Step-by-step explanation:

In the decimal of −12,405, leave the −12 and divide 405 by 1000 for now:

\frac{81}{200} = \frac{405}{1000}

Greatest Common Divisor [GCD]: 5

Finally, you attach this back to the −12, giving you -12\frac{81}{200}.

Find the values of x any y.
Ede4ka [16]

There are so many types of angles, let's see what we've got here!

--(5x - 17) and 48 are alternate interior angles, which means that they are congruent.

--(5x - 17) and y are supplementary angles.

--48 and y are same-side interior angles, which means that they are also supplementary.

Let's solve for x first.

5x - 17 = 48

5x = 65

x = 13

Now, let's solve for y.

48 + y = 180

y = 132

Hope this helps!! :)

The Louvre is an art museum in Paris. A glass square base pyramid sits in front of the entrance to the museum. If the pyramid is
Sveta_85 [38]

Answer:

lateral area = 2320 m²

Step-by-step explanation:

The question wants us to calculate the lateral area of a square base pyramid. The square base pyramid has a side of 40 meters.The height is 21 meters.

Half of the square base is 40/2 =  20 meters . With the height it forms a right angle triangle. The hypotenuse side is the slant height of the pyramid.

Using Pythagoras's theorem

c² = a² + b²

c² = 20² + 21²

c² = 400 + 441

c² = 841

square root both sides

c = √841

c = 29 meters

The slant height of the pyramid is 29 meters.

The pyramid has four sided triangle. The lateral area is 4 multiply by the area of one triangle.

area of triangle = 1/2 × base × height

base = 40 meters

height = 29 meters

area = 1/2 × 40 × 29

area = 580

area of one triangle = 580 m²

Lateral area = 4(580)

lateral area = 2320 m²
