30 workers can complete a work in 40 days in how many days would 20 men complete the construction​

Answers

Answer 1

Answer:

27

Step-by-step explanation:

(30 workers/40 days) = (20 workers/x days) cross multiply

30*x=40*20 divide by 30 both sides

x= 800/30

x≈26.67

So they will need 27 days

2. A line with a slope of 2 passes through (3,-2). Write the equation in Slope-Intercept Form.

Answers

1. y+2=2(x-3)
2. Y=2x-8

Explanation:

Point-Slope Form: y-y1 = m(x-x1)
(x1,y1) => (3,-2)

Y-(-2)=2(x-(3)) —> y+2=2(x-3)

Slope-Intercept Form: y=mx+b
(3,-2). M=2 (slope)

If you subtract a negative number to another negative number do you get a positive answer or negative?

Answers

Answer:

Negative

Step-by-step explanation:

Because Depending on which number is the biggest it's negative and the rules say the same signs add different subtract and keep the sign of the bigger number so

positive minus a negative= positive (6-3=3)

negative-positive= negative (-10+5= -5)

Example: What is 6 − (−3)? Yes indeed! Subtracting a negative is the same as adding!

Find the length of segment JK with endpoints J(4, 8) and K(-1, -2). Leave the answer as a radical. Simplify if necessary

Answers

Answer:

The length of segment JK is 5[tex]\sqrt{5}[/tex] ⇒ C

Step-by-step explanation:

The formula of the distance between the two points (x1, y1) and (x2, y2) is

d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]

Let us use the formula above to solve the question

∵ Jk is a line segment

∵ J = (4, 8) and K = (-1, -2)

x1 = 4 and y1 = 8

x2 = -1 and y2 = -2

→ Substitute them in the formula above

∵ JK = [tex]\sqrt{(-1-4)^{2}+(-2-8)^{2}}[/tex]

∴ JK = [tex]\sqrt{(-5)^{2}+(-10)^{2}}[/tex]

∴ Jk = [tex]\sqrt{25+100}[/tex]

Jk = [tex]\sqrt{125}[/tex]

→ Simplify the root

∵ 125 = 5 × 5 × 5

∴ [tex]\sqrt{125}[/tex] = 5[tex]\sqrt{5}[/tex]

JK = 5[tex]\sqrt{5}[/tex]

The length of segment JK is 5[tex]\sqrt{5}[/tex]

Heres a set of data 2.4, 1.6, 3.2, 0.3, 1.5 each peice of data is increases by 10, what is the mean? each new peice of data is doubles, whats the new mean?

Answers

Step-by-step explanation:

Mean is the ratio of the sum of the sample data to the total sample size.

1) Given the set of data 2.4, 1.6, 3.2, 0.3, 1.5, if each piece of data is increases by 10, the new data's will be;

(10+2.4), (10+1.6), (10+3.2), (10+0.3), (10+1.5)

sum of the new data's = 59

Sample size = 5

Mean = 59/5

Mean = 11.8

Hence if the price of data is increases by 10, its new mean will be 11.8

2) If each new piece of data is doubles, the new set of data will be;

2(2.4), 2(1.6), 2(3.2), 2(0.3), 2(1.5)

= 4.8, 3.2, 6.4, 0.6, 3.0

Sum of new data = 4.8+3.2+6.4+0.6+3.0

Sum of new data = 18

sample size = 5

Mean = 18/5

Mean = 3.6

Hence the new mean if the data were doubles is 3.6

Put these in order starting from the smallest

Answers

Answer:

1^8, 2^4, 5^2, 3^3 is the answer.

The numbers ordered from the smallest to the largest is [tex]1^{8} , 2^{4} , 5^{2} , 3^{3}[/tex].

What is the order of the numbers?

In order to determine the order of the numbers, we have to solve for the numbers. The power of a number can be solved by multiplying a number by its number of power.

[tex]5^{2}[/tex] = 5 x 5 = 25

[tex]1^{8}[/tex] = 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 = 1

3³ = 3 x 3 x 3 = 27

[tex]2^{4}[/tex] = 2 x 2 x 2 x 2 = 16
