Find the value of x. The diagram is not to scale.

a. x = 40
b. x = 23
c.x= 13
d. none of these

Answer:

[tex]\sqrt{21}[/tex] does not belong

Step-by-step explanation:

a rational number is defined by any number that ends or repeats.

[tex]\sqrt{36\\}[/tex] ends because it is just 6

[tex]\frac{2}{3}[/tex] repeats so it is rational

[tex]\frac{1}{5}[/tex] ends becuase it is just 0.2

but [tex]\sqrt{21}[/tex] does not end nor repeat, making it irrational

Answer:

21 is the irrational one

Step-by-step explanation:

you cant multiply to of the same whole numbers by itself and get 21

Answer: 36 / 2 1/4

Step-by-step explanation:

From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:

= 36 ÷ 2 1/4

From the expression we can then calculate the number of hours to drill. This will be:

= 36 / 2 1/4

= 36 / 9/4

= 36 × 4/9

= 16

He'll need to drill 16 holes

Answer:

18c

= 18(36)

= 648

Answer:

x = 250

Step-by-step explanation:

∠ ABC = 180° - 55° = 125°

The angle at the centre x is twice the angle on the circle , that is

x = 2 × ∠ ABC = 2 × 125 = 250

Answer:

Vertical change= 1

Horizontal change= 2

Rate of change=  1/2

Step-by-step explanation:

The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

Step-by-step explanation:

Answer:

b Huda found the product of –3 and 9 as positive.

yeah-

The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

First we need two points (x, y) to obtain the slope.

Assuming height to be 'y' and weeks to be 'x'.

Therefore, (0, 0) and (3, 10) are the two points.

Slope(m) = (10 0)/(3 - 0).

Slope(m) = 10/3.

Slope(m) = 3.33

Now, To obtain the y-intercept.

10 = 3(3.33) + b

b = 0.01 Or neglegible.

Therefore y = 3.3x.

Now, In the 6th week, the height of plant B will be,

y = 3.33(6).

y = 19.98 or 20 cm.

w= -12

Step-by-step explanation:

okay I understood it now. Here you go.

You’re welcome :)

Answer:

w= -12

Step-by-step explanation:

x both sides by 24

4w + 15 + -33

move the constant to the right  and change its sign

4w= -33 -15

calculate the difference ...

4w = -48

divide both sides by 4

w= -12
