Answer:
=> 24m²
Step-by-step explanation:
Area of small rectangle = l×b
=> 2m× 3m
=> 6m²
Area of large rectangle = L×B
=> 9m × 2m
=> 18 m²
Area of figure = area of small rectangle + area of large rectangle
=> 18 m² + 6m ²

There is a leak in a container that holds a certain nontoxic gas. Each hour, it loses 10% of its volume.
Write an equation that models the amount of gas left in the container after x hours, assuming there were 300 cubic centimeters in the container before the leak. Then use your equation to determine the amount of gas left in the container after 11 hours. Round your answer to the nearest tenth.
Answer:
94.1 cm^3 to nearest tenth.
Step-by-step explanation:
Each hour 100 - 10 = 90% of the gas remains.
90% = 0.90.
At 0 hours the volume = 300 cm^3
The equation is
Amount (V) after x hours = 300(0.90)^x.
The amount after 11 hours:
V = 300(0.90)^11
= 94.14
Answer:
y = 300(0.9)^x
94.1 cm³
Step-by-step explanation:
This is an exponential decay.
y = 300(0.9)^x
where x is the number of hours, and y is the amount after x hours.
y = 300(0.9)^11
y = 94.1

Using it's concept, it is found that there is a 0.183 = 18.3% probability that the person has completed a bachelor's degree and no more.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Researching this problem on the internet, it is found that 529 + 1054 = 1583 out of 1911 + 6730 = 8641 people aged 40 or older have completed a bachelor's degree and no more, hence the probability is given by:

Answer: b+95+34=180, b+129=180, 51
Step-by-step explanation:
b+95+34=180 works because the angles add to form a straight angle.
From this, we can obtain b+129=180 by adding the two constants.
Subtracting 129 from both sides, we get b=51.
Eduardo has a recipe that uses 2/3 cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? How many cups of flour will he need in total if he makes 3 more batches?
Answer:
4 batches: [tex]2\frac{2}{3}[/tex] cups
7 batches: [tex]4\frac{2}{3}[/tex] cups
Step-by-step explanation:
If he uses 2/3 cup of flour for each batch, then that is 2/3 four times, or 2/3 · 4.
[tex]\frac{2}{3}[/tex] × [tex]\frac{4}{1}[/tex]
= [tex]\frac{8}{3}[/tex] = [tex]2\frac{2}{3}[/tex]
If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to [tex]2\frac{2}{3}[/tex].
[tex]\frac{2}{3}[/tex] × [tex]\frac{3}{1}[/tex]
= [tex]\frac{6}{3}[/tex] = 2
[tex]2\frac{2}{3} +2[/tex] = [tex]4\frac{2}{3}[/tex]
Thus, [tex]2\frac{2}{3}[/tex] and [tex]4\frac{2}{3}[/tex] are the answers.

Jogging burns 375 calories in 45 minutes. Determine how many calories are burned per hour.
Answer:
500 calories an hour are burnt.
Step-by-step explanation:
45 is 3/4 of 60, so 375 is 3/4 of an hour of jogging. If we divide 375 by 3 we will get how many calories are burnt every 1/4 of an hour.
375 / 3 = 125
Now that we know what 1/4 of an hour equals we can add 125, 4 times to find the number of burnt calories in an hour of running.
125 + 125 + 125 + 125 = 500
that means jogging burns 500 calories an hour.
