Answer:

because their principal square roots are also positive integers, square roots of numbers which are not perfect squares like 2 are irrational

step by step:

The square of a number is the number you get ehen you multiply that bumber by itself. so if n is a number then nxn = n2 is the 'square of n' it is called that because the area of a square whose edge lengh is n units is n2 square units

perfect square numbers are the numbers which are ths squares of the positive integers

Answer: 8

Step-by-step explanation

Write as a decimal

7 11/18 is equal to 7.6111

Round the decimal to the nearest whole number:

If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.

If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.

Since 6 is in the tenths place we round up.  7 11/18 can be written as 8 (as whole number)

4.2

Step-by-step explanation:

Answer:

4.2

Step-by-step explanation:

1[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{1}{3}[/tex]

Divide [tex]\frac{1 x 5+2}{5}[/tex] by [tex]\frac{1}{3}[/tex] by multiplying [tex]\frac{1 x 5+2}{5}[/tex] by the reciprocal of [tex]\frac{1}{3}[/tex]

[tex]\frac{( 1 x 5 + 2) x 3}{5}[/tex]

Add 5 and 2 to get 7.

[tex]\frac{7 x 3}{5}[/tex]

Multiply 7 and 3 to get 21.

[tex]\frac{21}{5}[/tex]

Factor

[tex]\frac{3.7}{5}[/tex] = 4[tex]\frac{1}{5}[/tex] = 4.2

Using the concept of bias, it is found that the correct option is:

(A)  Employees may not want to give critical feedback in person to their manager, so this is likely an  overestimate of Valerie's performance.

Samples have to be well chosen, otherwise, there can be a source of bias. For example, if you want to make a survey about who is better, Pele or Maradona, if you choose only Brazilians, or only Argentinians, the results will be biased, thus a sample with an equal number of Brazilians and Argentinians should be used.

In this problem, Valerie's is their manager, and the employees may be reluctant to give her critical feedback, which means that the proportion of 83% is an overestimate, and the correct option is:

(A)  Employees may not want to give critical feedback in person to their manager, so this is likely an  overestimate of Valerie's performance.

Answer:

P (5 , 10)

Step-by-step explanation:

point A (1,4) and point D (7,13),         AP/PD = 2:1

P (x,y) : x = x₁ + (a/(a+b) * (x₂-x₁))       y = y₁ + (a/(a+b) * (y₂-y₁))    .... a=2 b=1

x = 1 + 2/(2+1) * (7-1) = 5

y = 4 + 2/(2+1) * (13-4) = 10

Answer:

The answer would be 84

Step-by-step explanation:

You divide  60 by 25 and get 2.4. Then multiply 30 by 2.4 to get 72. Finally, multiply 35 to get 84.

Hope this helps! Have a great day!!       **please give me brainliest :)

Answer:

84

Step-by-step explanation:

because you did 30=72 already and you just need to find the extra 5 mins

you do 25 divided by 5 =5

60 divided by 5=12

then do 30 mins (72) + 5 mins (12) = 35 mins (72+12+84)

Answer:

y = 5/3x + 1

y-intercept: (0, 1)

Step-by-step explanation:

In order to determine the linear equation in its slope-intercept form, y = mx + b, where m = slope, b = y-intercept:

You need two ordered pairs from the table to solve for the slope:

We'll use (6, 11) and (9, 16).

Let (x1, y1) = (6, 11)

(x2, y2) = (9, 16)

Substitute thes values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (16 - 11) / (9 - 6)

m = 5 / 3

Therefore, the slope of the line is: m = 5/3.

Next, we need to determine the y-intercept of the line. The y-intercept is the y-coordinate of the point (0, b ) where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.

To find the y-intercept, we'll use the slope, m = 5/3, and one of the ordered pairs from the table, (6, 11). Substitute these values into y = mx + b to solve for the y-intercept, (b ):

y = mx + b

11 = 5/3(6) + b

11 = 10 + b

Subtract 10 from both sides to solve for b:

11 - 10 = 10 - 10 + b

1 = b

The y-coordinate of the y-intercept, (0, b) is 1. The y-intercept as an ordered pair is (0, 1). For the linear equation in slope-intercept form, you'll use b = 1 to write the equation.

Therefore, given the slope, m = 5/3, and the y-intercept, b = 1:

The slope-intercept form is: y = 5/3x + 1

Step-by-step explanation:

Point A (0,0)

Point B (3,2)

Point C (9,6)

b. x values from A to B: 0 to 3

x values from B to C: 3 to 9

No, AB has a change of 3 and BC has a change of 6 in x

c. y values from A to B: 0 to 2

y values from B to C: 2 to 6

No, AB has a change of 2 and BC has a change of 4 in y

d. Calculate Slope: [tex]\frac{y{2}-y{1}}{x{2}-x{1}}[/tex]

AB (2-0/3-0) = 2/3

BC (6-2/9-3) = 4/6 = 2/3 simplified

Thus, AB has the same ratio of change as BC

Step-by-step explanation:

The smallest number of bags of each colour that he could buy is 60.

From the information, Ibrahim buys bags of coloured marbles. The blue marbles are sold in bags of 10 green marbles are sold in bags of 6 and white marbles are sold in bags of 12.

Since ibrahim wants to buy an equal number of blue ,green and white marbles, the smallest number of bags will be the lowest common multiple of the numbers. This will be:

6 = 6, 12, 18, 24, 30, 36, 42, 48, 54 and 60

10 = 10, 20, 30, 40, 50, 60

12 = 12, 24, 36, 48 and 60

The smallest common multiple is 60.

Answer:

48

Step-by-step explanation:

This question can be written as 3/4 times a number equals 36.

To multiply by 3/4 we would times 36 and 3 and then divide by 4.

We will do the opposite to find our unknown number

36 ÷ 3 = 12

12 × 4 = 48

The number of the solution will be 48.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

3/4 of a number is equal 36.

Now,

Let a number = x

So, we can formulate;

⇒ 3/4 of x = 36

Solve for x as;

⇒ 3/4 × x = 36

Multiply by 4 as;

⇒ 3/4 × 4x = 36 × 4

⇒ 3x = 36 × 4

Divide by 3, we get;

⇒ x = 36 × 4/3

⇒ x = 12 × 4

⇒ x = 48

Thus, The number of the solution will be 48.
