Answer:

s = 4t

Step-by-step explanation:

Let number of shoelace produced be S and time taken to produce then be T

If the number of shoelaces it produces is proportional to the time, this can be expressed using a direct relationship as:

S∝T

S = kT where

k is the proportionality constant

If 12 laces of shoes can be produced in 3 minutes, then S = 12 and T = 3

The relationship above on substitution becomes

12 = 3k

k = 12/3

k = 4

If the proportionality constant is 4, then the equation representing the relationship will be:

s = 4t

please mark me brainliest!

Answer: y = 4x (y = shoelaces & x = minutes)

Step-by-step explanation: We know that 12 shoelaces are produced in 3 minutes and that the ratio of shoelaces produced to minutes spent is proportional. We can figure out, therefore, that if you multiply the number of minutes by 4, you will get the number of shoelaces. As an equation, this would be y = 4x (y = shoelaces & x = minutes).

Answer:

a) 2.5x + 5  b) $5

Step-by-step explanation:

We know that the rate is 2.50 an hour, and she parked for 4 hours. Multiply 2.5 by 4 to get 10. This means that she spent 10 out of 15 of her dollars on the rate, meaning the initial fee was 5 dollars.

Answer:

a. y = 2.5x + 5

b. $5

Step-by-step explanation:

y = mx + b

m = slope is the fee per hour

b = y-intercept is the fixed fee

y = 2.5x + b

We know that she paid $15 for 4 hours, so we have point (4, 15). We now replace x and y in the equation with 4 and 15, respectively, and solve for b.

15 = 2.5(4) + b

15 = 10 + b

b = 5

a. The equation is:

y = 2.5x + 5

b. The initial fee is $5

Answer:A

Step-by-step explanation:

Answer:

bonds=22000

stock=4000

Step-by-step explanation:

let b  for bonds , and s for stock

b+s=26000

0.05 b +0.08 s=1420

to solve (by elimination)

1- multiply first equation with 0.05 to eliminate b

0.05 b+0.05 s=1300

0.05b+0.08s=1420

subtract two equations:

0.05b+0.05s-0.05b-0.08s=1300-1420

-0.03s=-120

s=120/0.03=4000

b+s=26000

b=26000-4000=22000

check:0.05(22000)+0.08(4000)=1420

Answer:

$22000

Step-by-step explanation:

x*0.05+(26000-x)*0.08= 1420

0.05x - 0.08x + 2080= 1420

0.03x=2080 -1420

0.03x= 660

x= 660/0.03

x= 22000

$22000 = 5% bonds

$4000 = 8% stocks

Answer:

Rs 1504

Step-by-step explanation:

Mr. Rai buys for Rs 1880.

He sells it to Mr. Sherpa at 20% discount.

1880 × 20%

= 376

1880 - 376

= 1504

Mr. Sherpa buys it for Rs 1504.

Answer:

Mr. Rai will be receiving $1504 if he sells the radio for 20%.

Step-by-step explanation:

To find a discount, move the decimal over twice on the percentage. After doing this, multiply that number by the original number. You will get a new number. Subtract the price by the new number and there is your answer.

For Example:

20% = .20

1880*.20= 376

1880-376= 1504

There is a simpler way of doing this as well. Multiplying by .8 (which is the remainder of 100% after taking away 20% if this makes sense) will give you the answer immediately. Hopefully this helps.

Good luck!

Answer:

This is a geometric sequence and the common ratio is equal to ½.

Step-by-step explanation:

For a sequence to be termed to be in arithmetic progression, the difference between consecutive terms are the same and constant.

On the other hand, a sequence is termed to be in geometric progression if the ratio of a term to the term before it is the same as the ratio between the next term to it.

Let's consider the sequence given: 12, 6, 3 . . .

=>Let's try to find the common difference if it would be constant: 6-12 (-6) ≠ 3-6 (-3)

The sequence is not arithmetic.

=>Let's also try to find the ratio of the sequence to see if it is constant:

6/12 (½) = 3/6 (½)

Therefore we can conclude the sequence is geometric because the common ratio (½) is constant.

This is a geometric sequence and the common ratio is equal to ½.

Answer:

x = 13

39° and 51°

Step-by-step explanation:

Angles in a triangle add up to 180 degrees.

This is a right angle triangle, so one side has a size of 90 degrees.

3x + 4x - 1 + 90 = 180

7x + 89 = 180

7x = 91

x = 91/7

x = 13

Put x as 13 to work out the size of the angles.

3(13) = 39

4(13) - 1

52 - 1 = 51

Answer:

[tex]x = 13 \\ [/tex]

Measure of the angles

[tex]39 \: \: degrees \\ 51 \: \: degrees[/tex]

Step-by-step explanation:

sum of the interior angles in a triangle= 180°

[tex]3x + 4x - 1 + 90 =1 80 \\ 7x + 89 =1 80 \\ 7x = 180 - 89 \\ 7x =9 1 \\ \frac{7x}{7} = \frac{91}{7} \\ x = 13[/tex]

x = 13,

now lets work out for the angles

[tex]3x \\ 3 \times 13 \\ = 39[/tex]

[tex]4x - 1 \\ 4 \times 13 - 1 \\ 52 - 1 \\ = 51[/tex]

Answer:

A) check attached picture

B) 272

C) 0.4478

Step-by-step explanation:

From the information given ;

A) The Venn diagram of the information can be found in the attached picture.

B) Number of students involved in both team sports and music.

n(student in sports team) = 385

n(students involved in music) = 450

Number of students involved in both music and team sport = y

Number of students not involved in either team sport or music = 87

Total number of students = 650

Therefore,

n(music alone) = 450 - y

n(team sport alone) = 385 - y

Adding the following:

n(music alone) + n(team sport alone) + n( both music and team sport) + n(neither music nor team sport) = Total number of students

450 - y + 385 - y + y + 87 = 650

922 - y = 650

922 - 650 = y

y = 272

Therefore, number of students involved in both music and team sport = 272

C) probability of being involved in team sport or in music.

P(being involved in music) = (450 - 272) / 650 = 0.2738

P(being involved in team sport) = (385 - 272) / 650 = 0.1738

P(involved in both) = 272 / 650 = 0.4184

P(involved in neither) = 87 / 650 = 0.1338

P(being involved in team sport) or p(being involved in music)

P(being involved in team sport) + p(being involved in music)

0.1738 + 0.2738 = 0.4478

Step-by-step explanation:

All we have to do is multiply the top with the top and the bottom with the bottom:

15(1) = 15

20(4) = 80

15/80

We have our answer, but we can simplify it by dividing top and bottom by 5:

15/5 = 3

80/5 = 16

We have our final answer, 3/16.

Answer:3/16

Step-by-step explanation:15/20 x 1/4

The numerator (the upper number) would divide the denominator (the lower number) or the denominator would divide the numerator.

15/20 x 1/4

15 and 20 have something in common which is 5.so 5 in 15 is 3,5 in 20 is 4

15/20 x1/4

3/4 x 1/4

= 3/16

2 points the first 3 matches then 3 points the last 2 matches

Step-by-step explanation:

12 points in 5 matches and the first 3 are all the same then the other 2 increased by 1 point

They got 2 points the first 3 matches then 3 points the last 2 matches

2 + 2 + 2 (first 3 matches) = 6

3 + 3 (last 2 matches) = 6

6 + 6 = 12

The zeroes of the function are 1 and 7 and multiplicity for zero 1 is two and for zero 5 is one.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

We have a polynomial function:

f(x) = (x – 1)(x – 1)(x + 7)

We can write it as:

f(x) = (x – 1)²(x + 7)

Here at x = 1 the given function becomes zero and (x-1) repeats two times, so the multiplicity is 2, and for x = -7 the multiplicity is 1.

Thus, the zeroes of the function are 1 and 7 and multiplicity for zero 1 is two and for zero 5 is one.

Translate 3 units to the left

Step-by-step explanation:

Answer:

The rectangles that have exactly 100 squares are 1 by 100  4 by 11 and 5 by 8

Step-by-step explanation:

The given parameters are;

A 2 by 3 rectangle contains 8 squares

A 3 by 4 rectangle contains 20 squares

A 4 by 6 rectangle contains 50 squares  

We note that the number of squares varies proportionately to the increase in the dimension of the rectangle, that is we have;

2 by  3 rectangle contains 8 squares

3 by 4 rectangle contains 20 squares increase by 12 = 3 × 4

4 by 5 rectangle contains 40 squares increase by 20 = 4 × 5

The number of squares formed can therefore be arranged in a matrix as follows(please see attached matrix);

Column,     1,       2,     3,      4,       5,     6,        7,       8,         9,           10,         11

Row

1

2

3

4

5

6

7

8

9

10

11

It will be observed that after reaching a point where the row and column are equal, (x, x) the rate of increase in the number of squares become constant and equal to x × ((x - 1) × 0.5) + 1) = x × (x + 1)/2

From the matrix, the rectangles that have exactly 100 squares are 1 by 100  4 by 11 and 5 by 8 and there are no more as presented in the attached matrix, the number of squares formed keeps increasing for each column and row added.

Answer:

25

Step-by-step explanation:

angle JKM and Angle MKL are supplementary. means, they add to 90degree. So to fing the missing one, just do 90 - 65. you'll get 25.

The angle MKL is equal to 155 which corresponds to the value of x=155.

The angle equal to 90 degree is called right angle and the triangle in which one angle is equal to 90 is called right angled triangle.

In the figure we can see that the value of angle JKL is equal to 90, value of angle JKM is 65 and we have been given that angle MKL is equal to x.

From the figure we can see that,

MKL=JKL+JKM

=90+65

=155 degree

Hence the value of x is equal to 155 degree.
