Area of the figure = 806.5 in²

Solution:

Length of the rectangle = 16 in

Breadth of the rectangle = 9 in

Area of the rectangle = length × breadth

= 16 × 9

Area of the rectangle = 144 in²

Base of the triangle = 31 in

Height of the triangle = 20 in

Area of the triangle = $\frac{1}{2}bh$

$$=\frac{1}{2}\times 31\times 20$

Area of the triangle = 310 in²

Parallel sides of the trapezium = 16 in and 31 in

Height of the trapezium = 35 – 20 = 15 in

Area of the trapezium = $\frac{1}{2}\times \text{Sum of the parallel sides}\times \text{Height}$

$$=\frac{1}{2}\times {(16+31)}\times{15}$

$$=\frac{1}{2}\times {47}\times{15}$

Area of the trapezium = 352.5 in²

Area of the figure = Area of rectangle + Area of triangle + Area of trapezium

= 144 in² + 310 in² + 352.5 in²

Area of the figure = 806.5 in²

Need help with this. Hope someone can help

To solve this problem, we must remember that the formula for volume is V = lwh, where l represents length, w represents width, and h represents height. Since we know the respective values for length, height, and volume, we can substitute those into the formula and then solve for the width, as modeled below:

30,000 cm³ = 30 cm * w * 500 mm

We must recognize first, though, that one of the values is given in millimeters, not centimeters. To continue solving this problem, we must convert this value to centimeters, using our knowledge that 1 cm = 10mm. This means that 500 mm = 50 cm, so we can substitute this into our equation below:

30,000 cm³ = 30 cm * w * 50 cm

To begin to solve this equation, we should first multiply all of the factors together on the right side of the equation, which gives us:

30,000 cm³ = 1,500w cm²

Next, we must divide both sides of the equation by 1,500 in order to get the variable w alone on the right side of the equation.

20 cm = w

Therefore, the width of the figure shown above is 20 cm.

Hope this helps!

It takes the hot water faucet twice as long to fill a bathtub as it does the cold water faucet. Left on together, the cold and h

Lerok [7]

Answer:

Step-by-step explanation:

Make a system of equations

Give the hot and cold faucets variables

Set x to be the minutes it takes for the hot water faucet to fill up the tub and Set y to be the minutes it takes for the cold water faucet to fill up the tub

She first equation is x = 2y because the hot faucet takes <em>2 times</em> as much time as the cold water

The second equation is x + y = 5 because if you add the number of minutes each takes to fill a tub, it will add up to 5 minutes

Now you have the equations

x = 2y

x + y = 5

So you can plug the first equation in for x in the second one to make

2y + y = 5

which equals 3y = 5

Then you divide 3 from both sides to get

y = $\frac{5}{3}$

Since y is the number of minutes the cold water faucet takes to fill the tub, then the cold faucet takes $\frac{5}{3}$ minutes for the cold water faucet to fill the tub itself
