Mary242 made for 11 hours of work.
MAVERICK [17]

We conclude that, if working at the same rate, to make 374 units, she needs to work for 17 hours.

<h3>At the same rate, how many hours would she have to work to make 374?</h3>

We know that Mary makes 242 units of something in 11 hours of work, then her rate of work is:

R = (242 units)/(11 hours) = 22 units per hour.

Now, if she wants to make 374 units, then she needs to work for a time T, such that:

(22 units per hour)*T = 374 units.

Solving that linear equation for T, we get:

T = (374 units)/(22 units per hour) = 17 hours

We conclude that, if working at the same rate, to make 374 units, she needs to work for 17 hours.

How do you Convert feet to metres<br>​
poizon [28]

The conversion of feet to meters is obtained by multiplying 1 foot = 0.3048 meters.

<h3>What are the basic measurements for length?</h3>

Foot, inches, centimeters, and meters are the basic measuring units for length.

<h3>What are the basic conversions?</h3>

The basic conversions are:

1 kilometer = 1000 meters

1 meter = 100 cm

1 cm = 10 mm

1 mm = 0.03937 inch

1 inch = 0.0833 feet.

<h3>How to convert feet to meters?</h3>

According to the international system of units,

1 foot = 12 inches ...(1)

But we know,

1 inch = 25.4 mm, 1 mm = 0.1 cm, and 1 cm = 0.01 m

By substituting all of these in equation (1), we get

1 foot = 12(25.4 mm)

         = 304.8 mm

         = 304.8 (0.1 cm)

         = 30.48 cm

         = 30.48(0.01 m)

         = 0.3048 meters

Therefore, 1 foot = 0.3048 meters.

Can someone plzzz hekppp meeee
erastova [34]

Answer:

Use this formula for these kinda things.

Step-by-step explanation:

Remember The z is the hypathonous, it means the biggest side.

{a}^{2}  +  {b}^{2}  =  {c}^{2}

where Z is going to be C

put this all together

{7}^{2}  +  {18}^{2}  =  {z}^{2}

put it into calculator, means 373=

{z}^{2}

therfore take the square root, it will be

z =  \sqrt{373}

which it will be 19.31

3 + root 3 *2 +root 2​
icang [17]

Answer:

6 + 3\sqrt{2} + 2\sqrt{3} + \sqrt{6}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

(3 + \sqrt{3} )(2 + \sqrt{2} )

Each term in the second factor is multiplied by each term in the first factor, that is

3(2 + \sqrt{2} ) + \sqrt{3} (2 + \sqrt{2} ) ← distribute both parenthesis

= 6 + 3\sqrt{2} + 2\sqrt{3} + \sqrt{6}
