If the crane operator works 30 years and the train engineer works 33 years, who makes the most lifetime income? How much more?

antiseptic1488 [7]

Answer:

The train eingineer.

Step-by-step explanation:

So, to find the lifetime income, we must multiply the annual income by the years of work.

So for the cran operator:

54,830*30

1,644,900

Now lets compare this to the train eingineer:

50,610*33

1,670,130

So looking at the two numbers:

<u>1,670,130(train eingineer)</u>>1,644,900(crane operator)

So the trian eignineer makes more than the crane operator.

Now lets find the amount.

To do this, lets subtract the larger value by the smaller value:

1,670,130-1,644,900

<u>25,230</u>

So the train eingineer made 25,230 more dollars than the crane operator.

Hope this helps!

Jeo is comparing the price of different boxes of cereal. One box has 16 oz. and costs $3.50. Another costs $3.89 for a 24 oz. bo

velikii [3]

Answer:

The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Step-by-step explanation:

☆Let's solve using proportion.

☆One box:

$\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x$

☆Another box:

$\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16$

☆All we need to do is subtract: $0.22 - 0.16 = 0.06$

☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Help me solve this with the steps please :/

Dima020 [189]

Answer:

Option (2)

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(42°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(42°) = $\frac{6}{\text{Width}}$

Width = $\frac{6}{\text{tan}(42)}$

Width = 6.67

Therefore, width of the given triangle is 6.67 units.

Option (2) is the correct option.
