Holding a ruler upright at arm’s distance (24 in.), Ronnie aligned the bottom of the ruler with a mark on the utility pole that
atroni [7]

Answer:

10 feet

Step-by-step explanation:

Drawing obviously not to scale but... Red segment is the ruler, at least the part between 5 and 6 inches, 1 inch long. Brown segment is the pole, ground to the top. Leftmost point is the eye, green line is the horizontal. The triangles are similar (AAA, the vertical lines are parallel), the ratio of the side is the same as the ratio of the heights. The height of the larger triangle (measured across the green line is

40 yd \times 3\frac{ft}{yd} \times 12\frac{in}{ft}= 1440''.

Ratio of the height is then 1440\div24 = 60.

At this point the height of the pole is 60 times the length of the measure on the ruler, or 60 inches, that is 5 feet. Add the 5 feet the pole was starting from, it's 10 feet.

A company has cups for its water cooler. Each cup has a height of 14 cm and the base has a radius of 3 cm. How much water is nee
Nitella [24]

Answer:

125 cups can hold  49.5 liters of water.

Step-by-step explanation:

The volume of the cup will tell how much water is needed to fill each cup.

The volume of the cup can be determined by the formula

V= base area* height

V= πr²* h

V= 22/7 (3)² (14)

V= 396cm³

125 cups can hold 125 * 396 cm³= 49500cm³

But 1 cm³= 0.001 Liters

Therefore = 49500*0.001= 49.5 liters

125 cups can hold  49.5 liters of water.

Find the equation of the line parallel to the line y = 2x + 3 and expect oy in (0; 1)
nignag [31]

Step-by-step explanation:

Any lines that are parallel to each other have the same slope (coefficient of x is the same)

In this case, y = 2x + c.

Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.

Hence, the equation of the parallel line is y = 2x + 1.
