How do you solve the problem and what should I write?

Answers

Answer 1

Step-by-step explanation:

32+49+27+12 = 120

= (32/120) * (12/119)

= (32/10) * (1/119)

= (16/5) * (1/119)

= 16/595

The mistake Descartes He didn't minus one from the total number of fishes that could be caught.

The correct answer should be 16/595

Carlo and his brother, agreed to buy a bicycle by sharing out the cost. The ratio of the amount of money paid by Carlo to that paid by his brother was 5: 2. The bicycle cost P3500. Find the amount paid by each of them.

Answers

Answer:

Carlo paid 2500 dollars and his brother paid 1000 dollars

Step-by-step explanation:

Given -

The ratio of cost shared by Carlo and his brother is 5:2

Which means Carlo paid 5/7th part of the total cost of bicycle

5/7 * 3500 = 2500 dollars

The amount paid by his brother is 3500 - 2500 = 1000 dollars

Answer:

(5a-3)(3b+7)

Step-by-step explanation:

Identify the factors of 15ab + 35a − 6b − 14

Given Data

15ab + 35a − 6b − 14

We have expression

15ab + 35a − 6b − 14------------

5a(3b-7)-3(2b+7)

Hence the factors are

(5a-3)(3b+7)

Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 35 h from the time Henrietta started the experiment. I need help asap please

Answers

Answer:

See below

Step-by-step explanation:

Given

Initial number of bacteria = 800Growth rate = 3.2% = 1.032 times

Required equation:

B(t) = 800(1.032)^t, where B- number of bacteria, t- time in hours

The y-intercept is:

B(0) = 800*1.032^0 = 800The point (0, 800)

Bacteria population 35 in hours:

B(35) = 800*1.032^35 = 2409The point (35, 2409)

the first 4 terms of a 10-term geometric series are listed below. Which expression represent the sum of the series? need ASAP
16/25+8/5+4+10+...+a^10

Answers

Using geometric sequence concepts, it is found that the sum of the first 10 terms is of 4068.6.

What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The sum of the first n terms is given by:

[tex]S_n = \frac{a_1(q^n-1)}{q - 1}[/tex]

In this problem, the sequence is:

[tex]\frac{16}{25}, \frac{8}{5}, 4, 10,...[/tex]

Hence:

[tex]a_1 = \frac{16}{25}, q = \frac{10}{4} = 2.5[/tex]

Then, the sum of the first 10 terms is:

[tex]S_{10} = \frac{\frac{16}{25}(2.5^{10}-1)}{2.5 - 1} = 4068.6[/tex]

A bag with 10 marbles has 2 yellow marbles, 4 blue marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?

Answers

Answer:

P(Y) = 2/10 = 1/5

Step-by-step explanation:

From the above question:

Total number of marbles = 10 marbles

Number of yellow marbles = 2 yellow marbles

Number of blue marbles = 4 blue marbles

Number of red marbles = 4 red marbles.

The probability of choosing a marble that is yellow is calculated as:

= P(Y) = Number of yellow marbles/Total number of marbles

P(Y) = 2/10

P(Y) = 1/5

6. The swing set on the playgrounds is getting wobbly, and you have been asked to put outrigger boards to help stabilize it. If the crossbar of the swing is 10 feet off of the ground, the outrigger to be attached at a 40 degree angle, and you want to bury the outrigger boards 3 feet onto the ground, how long would the boards have to be? (Hint: the outrigger is the hypotenuse of a right triangle)

Answers

Answer:

[tex]X=18.6ft[/tex]

Step-by-step explanation:

From the question we are told that:

Height of swing's crossbar [tex]H=10ft[/tex]

Angle [tex]\theta=40 \textdegree[/tex]

Depth of outrigger [tex]d_=3ft[/tex]

Generally the equation for slant height l is mathematically given by

[tex]l=\frac{opposite}{sin\theta}[/tex]

Therefore

[tex]l=\frac{H}{sin\theta}[/tex]

[tex]l=\frac{10}{sin 40\textdegree}[/tex]

[tex]l=15.6ft[/tex]

Since the Depth of outrigger

[tex]d_=3ft[/tex]

Therefore Length of the board X

[tex]X=l+d[/tex]

[tex]X=15.6+3[/tex]

[tex]X=18.6ft[/tex]
