I'm confused on finding the area of this question​

Answer:

7200 cm²

Step-by-step explanation:

You need to do two things before calculating the area:

1) All lengths must be in the same unit.

2) Divide the compound figure into two rectangles.

See the picture below.

Use the conversion 1 m = 100 cm to change the two lengths in m to cm.

2 m = 2 × 100 cm = 200 cm

4 m = 4 × 100 cm = 400 cm

area of rectangle = length × width

total area = 12 cm × 200 cm + 12 cm × 400 cm

total area = 2400 cm² + 4800 cm²

total area = 7200 cm²

Answer:

The area of the given figure is 7200 cm² or 72 m²

Step-by-step explanation:

For the given figure we divide this in two rectangle

i.e., Rectangle A and Rectangle B

So,

<h3><u>Rectangle A</u></h3>
  • Length (l₁) = 2 m = 200 cm
  • Breadth (b₁) = 12 cm
<h3><u>Rectangle</u><u> </u><u>B</u></h3>
  • Length (l₂) = 4 m = 400 cm
  • Breadth (b₂) = 12 cm

Here, Area of Rectangle A

A = (l₁) × (b₁)

A = 200 × 12 cm

A = 2400 cm² or 24 m²

Now, Area of Rectangle B

A = (l₂) × (b₂)

A = 400 × 12 cm

A = 4800 cm² or 48 m²

Now,

Area of figure

= Area of Rectangle A + Area of Rectangle B

= 2400 cm² + 4800 cm²

= 7200 cm² or 72 m²

Thus, The area of the given figure is 7200 cm² or 72 m²

The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. T
svlad2 [7]

Answer:

250.50 - 35m = 300 - 45.25m

Step-by-step explanation:

Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other

The equation will be 250.50 - 35m = 300 - 45.25m

The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m

Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.

The National Center for Educational Statistics surveyed 5400 college graduates about the lengths of time required to earn their
fenix001 [56]

Answer:

The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645*\frac{1.9}{\sqrt{4500}} = 0.04

The lower end of the interval is the sample mean subtracted by M. So it is 5.4 - 0.04 = 5.36 years.

The upper end of the interval is the sample mean added to M. So it is 5.4 + 0.04 = 5.44 years.

The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.

In the equation y=mx+b, what does the x stand for? And, in the equation y=3x+6 how would I solve for y?
ladessa [460]

Answer:

x stays x in both equations so x stands for x

Step-by-step explanation:

y=3x+6

you can put this into a graphing caculator or draw it yourself.

6 is the y value when x equals 0. and the 3 represents the slope so then it is solved for any y value

Kruka [31]

Answer:

1/14:5/7:3/14

Step-by-step explanation:

Since orange=15

Apple=5

Coconut milk=50

50+15+5

70

So

Orange=15/70

Divide both by 5

=3/14

Apple=5/70

Divide both by 5

=1/14

Coconut milk=50/70

Divide both by 10

=5/7

So the ratio of apple to coconut to orange
