What is 0.02349 written in standard form to 3 significant figures
Answer: The answer is (B)
Explanation: The answer is (B) because, there are 2 zeros so that means that there would have to be a 2 behind the 10 and then there is 2,3,4,and 9. We take out the 9 and use the other numbers, bring over the decimal and now you have [tex]2.34 x 10^{2}[/tex] .
Let's cancel out from left to right
[tex]\\ \sf\Rrightarrow 0.02349[/tex]
[tex]\\ \sf\Rrightarrow 0.0235\times 10^{-1}[/tex]
[tex]\\ \sf\Rrightarrow 2.35\times 10^{-3}[/tex]

X, Y, and Z are collinear and Y is between X and Z. If XY = 3x – 1, YZ = 5, and XZ = 5x – 8,
what is the value of x?
a. 6
b. 4
c. 10
d. 8
Answer:
6
Step-by-step explanation:
XY = 3x – 1, YZ = 5, and XZ = 5x – 8,
We know that XY + YZ = XZ, so
3x - 1 + 5 = 5x - 8
3x + 4 = 5x - 8
3x + 12 = 5x
12 = 2x
6 = x
The value of x from the given line segment XZ is 6. Therefore, the correct answer is option A.
Given that, X, Y, and Z are collinear and Y is between X and Z.
Collinear points are those that are on the same straight line or in the same plane. In Euclidean geometry, two or more points on a line that are close to or far from each other are said to be collinear.
So, here [tex]XZ=XY+YZ[/tex]
[tex]5x-8=3x-1+5[/tex]
[tex]5x-8=3x+4[/tex]
[tex]5x-3x=4+8[/tex]
[tex]2x=12[/tex]
[tex]x=6[/tex]
Therefore, the correct answer is option A.

12. Name the angle included between AB and AD.
Answer fast
Answer: Either angle DAB or angle BAD
Explanation:
The segments AB and AD have the point A in common. So this common point is the middle letter of the angle name. We could go for angle DAB or angle BAD as they both name the same exact angle. The order doesn't matter as long as the middle letter is fixed like this.

If the radius is 18 cm and the angle at centre of circle is 120° then the
area of sector is? Use pi as 3.142 *
The area of a sector is 339.336 cm²
The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.
It can be determined by using the formula:
[tex]\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }[/tex]
Given that;
Radius r = 18 cmAngle θ = 120°Then. the area of the sector can be calculated as:
[tex]\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }[/tex]
[tex]\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }[/tex]

Plot the value(s) on the number line where this function is equal to zero: fx) = (x + 5)(x - 1).
Answer:
x = - 5, x = 1
Step-by-step explanation:
let f(x) = 0 , that is
(x + 5)(x - 1) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 1 = 0 ⇒ x = 1
Plot the points - 5 and 1 on the number line
