28 And/or 29 Pls. Find The Value Of X And Y.

Answers

Answer 1

Answer:

Step-by-step explanation:

for y

take 30 degree as reference angle using sin rule

sin 30=opposite/hypotenuse

1/2=9/y (do cross multiplication)

2*9=y

18=y

for x

using pythagoras theorem

a^2+b^2=c^2

9^2+x^2=18^2

81+x^2=324

x^2=324-81

x^2=243

x=[tex]\sqrt{243[/tex]

x=9[tex]\sqrt{3[/tex]

The graph shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours since the start of the experiment.

Based on the graph, what is the approximate number of bacteria after 16 hours?
6 bacteria
8 bacteria
60 bacteria
80 bacteria

Answers

Answer:

The input for the method is a continuous function f, an interval [a, b], and the function values f(a) and f(b). The function values are of opposite sign (there is at least one zero crossing within the interval). Each iteration performs these steps: Calculate c, the midpoint of the interval, c = a + b2.

Let p: A number is greater than 25.

Let q: A.number is less than 35.

If p ^ q is true, then what could the number be? Select two options.

Answers

Answer:

Here we do not have the options, so I will answer in a general way.

We have two statements:

p = A number is greater than 25

q = A number is less than 35

We want to have:

p ^ q is true

This means:

p and q are true.

So, we need to find a number such that both conditions are meet, so we need to find a number N such that

The number N is greater than 25  (from p)

The number N is less than 35 (from q)

So N can be any number between 25 and 35

So, some of the possible values of N are:

N = 26

N = 27

N = 28.6

N = 33

N = 34

Concluding, any number N ∈ (25, 35) can be a solution.

(Note that N = 25 and N = 35 are not solutions)

Given that (1,4) is on the graph f(x), find the corresponding points of a function 1/4f(x)

Answers

Answer:

(1,1)

Step-by-step explanation:

In the equation f(x), you are plugging in the x coordinate which in this case is one. That means in 1/4f(x), x will remain the same, because you are still plugging in the same thing. What will change is the y coordinate. 1/4f(x) is saying that the y coordinate will be a fourth of the original y coordinate(4). 4 times 1/4 is equal to one.

If the x coordinate stays the same, and the y coordinate is a fourth of 4, the corresponding points in the function f(x) will be (1,1)

Gloria set aside $100 to buy school lunches for the year. Each school lunch cost $2. The inequality 100 – 2x < 20 can be used to find the number of school lunches Gloria can buy before she has less than $20 left. What is the solution to this inequality?

Answers

Answer:

she would be able to buy 40 lunches

Step-by-step explanation:

Subtract  100  from both sides of the inequality

Divide each term by   −2  and simplify.

The solution to the inequality 100 – 2x < 20 is x > 40

How to find solution to an inequality?

She set aside $100 to buy school lunches for the year. Each school lunch cost $2.

Therefore, the inequality can be used to find the number of school lunches Gloria can buy before she has less than $20 left.

100 – 2x < 20

The solution of the inequality is as follows;

100 – 2x < 20

subtract 100 from both sides

100 - 100 - 2x < 20 - 100

-2x < - 80

divide both sides by -2

x > 40

The (blank) of a power is the common factor. 1. Exponent 2. Square root 3. Power 4. Scientific notation 5. Marginal frequency 6. Base

Answers

Answer:

6. Base

Step-by-step explanation:

In Mathematics, a power involves the multiplication of factors repeatedly. Thus, it's simply a multiplication (product) of repeated factors.

The base of a power is the common factor. When working with a power, the base is the number that is the common factor.

For example;

10⁴ = 10 * 10 * 10 * 10

Therefore, the base in the above expression is 10.

Additionally, the exponent is 4 and it represents the number of times the base "10" was used as a factor.

if 20% of ms.moore's class earned a d how many of her 30 students earned a d what percent of students earned a different grade

Answers

Answer:

6 students earned a d and 80% got other

Step-by-step explanation:

Answer:

6 students, 80% of students

Step-by-step explanation:

20% of her 30 students earned a D. To find exactly how many students earned a D, we can convert the 20% into a fraction and thereby multiply the fraction by 30.

[tex]20[/tex]%[tex]=[/tex]

[tex]\frac{20}{100}=\\\frac{1}{5}[/tex]

Ok, [tex]\frac{1}{5}[/tex] of Ms. Moore's 30 students earned a D. Let's multiply.

[tex]\frac{1}{5}*\frac{30}{1} =\\6[/tex]

6 students in Ms. Moore's class earned a D.

Therefore, the rest of the class earned a different grade. [tex]30-6=24[/tex] students had a different grade. To find the percentage, we simply divide by the total number of students and multiply by 100%

[tex]\frac{24}{30} =\\\frac{4}{5} =\\0.8=[/tex]

[tex]80[/tex]%

80% of students in Ms. Moore's class got a grade other than D.

2. During her daily run, Mira looks at her fitness monitor and sees that she has run 9 miles so far. If this distance is 30% of the total distance she plans to run, how many total miles does Mira plan to run?

Answers

Answer:

[tex]let \: total \: distance \: be \: x \\ 30\% \: of \: x = 9 \\ \frac{30}{100} \times x = 9 \\ 30x = 900 \\ x = 30 \\ total \: distance = 30 \: miles[/tex]

The total distance Mira plan to run is 30 miles.

What is percentage?

Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the symbol ‘%’. For example, 25% is the same as 25/100 or 0.25. Percentages are used to express how large or small one quantity is relative to another quantity.

Given that, Mira has run 9 miles.

Let the total distance be x miles.

Distance is 30% of the total distance she plans to run

Here, 30% of x =9

30/100 ×x=9

30x=900

x=900/30

x=30

Therefore, the total distance Mira plan to run is 30 miles.

y is directly proportional to the square of x. given that y = 50 when x = 5, find the value of y when x = 3​

Answers

Answer:

y = 18

Step-by-step explanation:

Given y is directly proportional to x² then the equation relating them is

y = kx² ← k is the constant of proportion

To find k use the condition y = 50 when x = 5

50 = k × 5² = 25k ( divide both sides by 25 )

2 = k

y = 2x² ← equation of proportion

When x = 3 , then

y = 2 × 3² = 2 × 9 = 18

The human resources managet at a company records the length in hours of one shift at work, X. He created the probability distribution below. What is the probability that a worker chosen at random works at least 8 hours?​

Answer:

The probability that a worker chosen at random works at least 8 hours is 0.83

Step-by-step explanation:

Given

See attachment for probability distribution

Required

[tex]P(x \ge 8)[/tex]

At least 8 hours means that a worker works for 8 hours or more.

So:

[tex]P(x \ge 8) = P(x = 8) + P(x = 9) + P(x = 10)[/tex]

By reading the probabilities from the graph, we have:

[tex]P(x \ge 8) = 0.61 + 0.14+ 0.08[/tex]
