Speedy crawled 5/9 yards. Slimy crawled 4 times as far as speedy. How far did slimy crawl?

ELEN [110]

Answer:

2 2/9 yards or 20/9 yards

Step-by-step explanation:

Slimy went 4 times as much as Speedy did so that means 5/9 x 4 yards which is the same thing as 5 x 4/9 so 5 x 4/9 equals 20/9 or 2 2/9 so Slimy crawled 2 2/9 yards.

A mosaic tile is shown below. Dan wants to cover a 600-square-inches area. How many mosaic tiles does Dan need?

alina1380 [7]

Answer:

B. 30

Step-by-step explanation:

The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;

Area of a trapezium = $\frac{1}{2}$ (a + b)h

where: a and b represent the length of its plane sides, and h is the height.

Area of a mosaic tile = $\frac{1}{2}$ (4 + 6) 4

= 10 x 2

Area of a mosaic tile = 20 square inches.

But, Dan wants to cover a 600 square inch area.

So that the number of tiles needed = $\frac{600}{20}$

= 30

The number of mosaic tiles needed by Dan is 30.
