David is making a wall out of bricks. Each brick is 2/3 foot long. There are 20 bricks lined up end to end to make the wall. Wha

Law Incorporation [45]

The total length of wall is 160 inches

Solution:

Given that,

$Length\ of\ each\ brick = \frac{2}{3}\ foot$

1 feet = 12 inches

Therefore,

$Length\ of\ each\ brick = \frac{2}{3} \times 12\ inches = 8\ inches$

There are 20 bricks lined up end to end to make the wall

To find: Total length of wall in inches

$Total\ length\ of\ wall = \text{length of each brick } \times \text{ total number of bricks}$

Thus we get,

$Total\ length\ of\ wall = 8 \times 20\\\\Total\ length\ of\ wall = 160\ inches$

Thus total length of wall is 160 inches

You can upgrade lighting at your factory to LED bulbs that cost $6.95 each and last an average of 5 years. It costs S3 in labor

marshall27 [118]

Answer:

11.95 dollars

Step-by-step explanation:

Cost of one LED bulb = 6.95 dollars

Cost of changing one bulb = 3 dollars

Life of each bulb = 5 years.

In 10 years, only one time after 5 years the bulbs would have been changed

Hence cost of 100 lamps = 695 and

cost of changing once = 500

Total cost = 1195 dollars for 11 years

Divide this by 10 years to get average cost per year

Cost of 100 lamps per year = 1195/100 = 11.95 dollars

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or

belka [17]

Answer:

z = 29°

Step-by-step explanation:

We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°
