A certain project can be completed by 28 men in 90 days. the numbers of men needed varies inversely to the time needed to comple
leva [86]

ANSWER

C. 35 men

EXPLANATION

Let m represent the number of men needed and d represent the number of days.

From the question,the number of men needed varies inversely to the time needed to complete the project.

We can write the inverse variation equation.

m =  \frac{k}{d}

where k is the constant of variation.

When m=28, d =90.

We substitute these values into the variation equation to determine the value of k.

28 =  \frac{k}{90}

k = 90 \times 28

k = 252

Now the equation becomes:

m= \frac{2520}{d}

When d=72,

m =  \frac{2520}{72}

m = 35

Therefore he needs to have 35 men working.

One of the legs of a right triangle measures 1 cm and its hypotenuse measures 2 cm.
FromTheMoon [43]

Answer:

1.7 cm

Step-by-step explanation:

The formula to find the hypotenuse: c^{2} = a^{2} +b^{2}. In this case, the hypotenus is given.

1) Substitute the values into the formula.

2^{2} = 1^{2} +b^{2}

2) Solve for b.

4 = 1 + b^{2} \\4 - 1 = b^{2}\\3 = b^{2}\\\sqrt{3} = b\\1.73205 = b

3) Round the answer to the nearest tenth.

1.7 = b
