In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if
a=2sqrt3 , c=2b ?
Answer: b = √6
Step-by-step explanation: Use the Pythagorean Theorem to solve this.
a² + b² = c²
Plug in your values:
2√3² + b² = 2b²
When a square root is squared, the square root is cancelled out so you will be left with this:
2(3) + b² = 2b²
Subtract b² from both sides so you’re left with:
6 = b²
Now, to get rid of the square, just square root both sides:
√6 = √b²
Since the √6 is not a perfect square, leave it in the radical. Then, you get your answer:
b = √6
Answer:
the answer:b is equivalent to 2

Odds of an event occurring given probability 1/5
Answer:
1/4
Step-by-step explanation:
Probability = successes / all events
Odds = successes / failures
If the probability is 1/5, then there's 1 success for every 4 failures.
So the odds are 1/4.

7. A student is paid K50 for each day he works and fined K25 for each day he failst work. After 20 days, he is paid K700. For how many days has he worked?
Answer:
14
Step-by-step explanation:
The student is paid K50 each day so after 20 days they should have K1000 but he is paid K700 which means they missed some days of work.
So we divide K700 by K50 which then gives us 14, therefore the student worked 14 days out of 20.

What would be the answer of 5(x-2)=30 in dustributive property
Answer:
x = 8
Step-by-step explanation:
5(x-2)=30
Distribute
5x- 10 = 30
Add 10 to each side
5x-10+10 = 30+10
5x= 40
Divide by 5
5x/5=40/5
x = 8
Answer:
x=
Step-by-step explanation:
using distributive property, you multiply 5 by x and by 2, which gets you 5x and 10
5(x-2)=30
5x-10=30
5x=40
x=8
Food poisoning occurs when bacteria like Salmonella and Listeria grow on food. These microorganisms grow at an
exponential rate. When an initial population of 100 bacteria are left at 98.6°F, they will grow at a rate of b= 100(8)". Which
graph could be used to calculate the number of bacteria after a certain number of hours?
The function that shows the number of bacteria after a certain number of hours is y = 100(8)ˣ
What is an exponential function?An exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y represent the amount of bacteria after x hours. Hence:
y = 100(8)ˣ
The function that shows the number of bacteria after a certain number of hours is y = 100(8)ˣ

Zucchini weights are approximately normally distributed with mean 08 pound and standard deviation 0.25 pound. Which of the following shaded regions best represents the probability that a
randomly selected zucchini will weigh between 0 55 pound and 13 pounds?
Answer:
The correct option is A
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 0.8 \ pounds[/tex]
The standard deviation is [tex]\sigma = 0.25 \ pounds[/tex]
Generally the the probability that a randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as
[tex]P(0.55 < X < 1.3) = P(\frac{0.55 - 0.8}{ 0.25} < \frac{X - \mu}{\sigma } < \frac{1.3 - 0.8}{0.25})[/tex]
=> [tex]P(0.55 < X < 1.3) = P( -1 < Z < 2 )[/tex]
So looking the option of normal curves given in the question we see that it is option A that matches our interval

5. Which graph represents a function?
Answer:
bottom left, the one that looks like a v
Step-by-step explanation:
You can test if something is a function by looking to see if there is a place where an x has 2 ys. if there are 2 ys for an x it is not a function.
Answer:
bottom left
Step-by-step explanation:
Bottom right is not a function because you would get an infinite number of results. It does not exactly map one output of this function.
The top two graphs are incorrect because they have more than 1 output. You can do the Vertical Line test and see that the top two graphs do have more that one output.
In order for it to be a function it has to have one output.
What is the gradient of the graph shown?
Answer:
-1
Step-by-step explanation:
Gradient is another word for slope, and slope can be defined as rise/run.
From the point (0,0) to (1,-1), it moved one unit down and one unit to the right. The slope for this line can be represented as -1/1, which is equal to -1.
Therefore, the gradient of the graph shown is -1.
I spent 3/4 of my money and then I spent 1/5 of what was left. What part of all my money did I spend? (10 points)
Answer: 80% or 4/5
Step-by-step explanation:
Look at this as a percentage:
3/4=75%
1/5=20%
Lets say you have 100$
75% of $100 leaves you with $25
20% of the remaining $25 gives you $20
$100-$20=80% or 4/5

139 miles
explanation:
$1 → 100 cents
Here the base fee is fixed.
make equation:

Hector purchased a brand new 2019 BMW 760.
The cost of the vehicle was $97,899.99. There is a
25% discount for cash customers, Hector paid
cash. The sales tax rate for the vehicle was 3.75%.
What was the total price of the purchases
(SHOW ALL WORK)
(PLEASE HELP)
Answer:
Step 1: Calculate percentage discount
=> $97,899.99 × 25/100
=> 97,899.99/1 × 25/100
{multiply the numerator by the numerator and the denominators by the denominators}
=> 2,447,499.75/100
divide 24,474.9975 by 100
=> 24,474.9975
=> 24,474.9975
{Substract 24,474.9975 from 97,899.99.}
=> 97,899.99 - .24,474.9975
=> 73,424.9925
Step 2: Calculate sales tax rate
Sales tax rate = price × rate/100
=> 73,424.9925 × 3.75/100
=> 275,343.7/100
=> 2,753.437
Add to 73,424.9925
=> 73,424.9925 + 2,753.437
=> 76,178.4295
=> 76,178.4 { Rounded to 1 dp)
Therefore, the total price of the purchases is 76,178.4295

b. How would you model your equation on a number line to show your answer?
Real-world situations can be modeled with equations and represented on a real number line. In this exercise, positive
ten represents the $10 given as a birthday gift because it is a gain. Negative four represents the $4 spent on snacks
because it is a loss. Gaining $10 and then taking away $4 leaves you with $6.
