5x4y3 * 3x3y8 need help
Answer:
15x^7y^11
Step-by-step explanation:
First, multiply the coefficients 5 and 3 together. We get:
15x^4y^3 * x^3y^8
Please note that it's mandatory to use " ^ " to indicate exponentiation.
Since x^4*x^3 = x^7, we next obtain:
15x^7y^11
Find the shaded area.
Answer: ≈ 21.46 m²
Step-by-step explanation:
Area of square = 10 x 10 = 100 m²
Area of circle = π(5²) = 25π m²
Area of total = 100 - 25π = 21.46018366
≈ 21.46 m²

Answer:
= 222q^8 - 5m + 20n -37 + 21
Step-by-step explanation:
−5(m−4n−5)−37(p−6q8)−4
step 1
=(−5)(m)+(−5)(−4n)+(−5)(−5)+(−37)(p)+(−37)(−6q8)+−4
=−5m+20n+25+−37p+222q8+−4
step 2
=−5m+20n+25+−37p+222q8+−4
=(222q8)+(−5m)+(20n)+(−37p)+(25+−4)
=222q8+−5m+20n+−37p+21
The Richter scale magnitude reading m is given by m=log10x , where x represents the amplitude of the seismic wave causing ground motion. Determine the reading of an earthquake that is 10 times less intense than an earthquake that measures 4.5 on the Richter scale.
Answer: The reading would be 5.5 on the Richter scale.
Step-by-step explanation:
The intensity of an earthquake that measures 4.5 on the Ritcher scale can be found by solving:
4.5 = log₁₀(x)
for x.
remember that:
logₐ(x) = ln(x)/ln(a)
Then we can rewrite our equation as:
4.5 = ln(x)/ln(10)
4.5*ln(10) = ln(x)
we also know that:
ln(exp(x)) = exp(ln(x)) = x
Then we can apply the exponential equation to both sides to get:
exp( 4.5*ln(10)) = exp( ln(x) ) = x
exp( 4.5*ln(10)) = x
x = 31,622.8
Now, if we have an intensity 10 times larger than this, we will have:
x = 10*31,622.8 = 316,228
The reading on the Richter scale will be:
m = Log₁₀(316,228) = 5.5
The probability that Jamil will be late for work is 0.2.
Work out the probability that Jamil will not be late for work.
Given:
The probability that Jamil will be late for work is 0.2.
To find:
The probability that Jamil will not be late for work.
Solution:
We have,
P(Jamil will be late) = 0.2
We know that,
P(Jamil will not be late) = 1 - P(Jamil will be late)
= 1 - 0.2
= 0.8
Therefore, the probability that Jamil will not be late for work is 0.8.

How can you find the town with a temperature that is the opposite of -4°C? Name the town with that temperature
Answer:
Town B
Step-by-step explanation:
Given
See attachment
Required
Which town answers the question
From the attachment, the temperature of town J is -4°C.
This can be represented as:
[tex]J = -4^{\circ}C[/tex]
The opposite of -4 is 4.
So, the town with the temperature that is opposite of -4°C must have a temperature of 4°C.
From the attachment, the temperature of town B is 4°C.
This can be represented as:
[tex]B = 4^{\circ}C[/tex]
Hence, the answer to the question is town B

Louis makes a model of a plane.
The wingspan of the model is 50 centimetres.
The wingspan of the real plane is 80 metres.
Work out the scale of the model.
Give your answer in the form 1:n
Answer:
1 : 1.6
For every centimeter on the model, it is 11.6 centimeters on the real plane
Step-by-step explanation:
The required value of the scale of the model in the form of 1:160.
Given that,
The wingspan of the model is 50 centimeter,
The wingspan of the real plane is 80 meter.
We have to determine,
The scale of the model and give your answer in the form 1 : n.
According to the question,
The wingspan of the model = 50 centimeter [tex]= \frac{50}{100} = 0.5m[/tex]
The wingspan of the real plane is 80 meter.
The ratio of the scale = 1:n
Therefore,
The equation of proportion is,
[tex]\frac{wingspan \ of \ the \ model}{wingspan\ of \ the \ palne} = \frac{1}{n}[/tex]
Putting all the values in the equation,
[tex]\frac{0.5}{80} = \frac{1}{n} \\\\n = \frac{1 \times 80}{0.5} \\\\n = 160[/tex]
The value of n = 160.
Hence, The required value of the scale of the model in the form of 1:160.
