The total number of significant figures in C is 5 because when the two numbers are multiplied then the result obtained has the least significant figure.

Given :

  • Lillian multiplies two numbers.
  • A has five significant figures and two decimal places and B has six significant figures and four decimal places.

The following steps can be used in order to determine the total number of significant figures of C:

Step 1 - According to the given data, 'A' has five significant figures and two decimal places and 'B' has six significant figures and four decimal places.

Step 2 - It is also given that C is equal to A times B.

Step 3 - So, the total number of significant figures in C is 5 because when the two numbers are multiplied then the result obtained has the least significant figure.

Therefore, the correct option is C).

Rule that maps each preimage
Yuri [45]
The answer to this question would be 
5= rotating 90° clockwise
6= mirrored diagonally (\)

In this case, the picture in number 5 is moved 1 quadrant to the clockwise direction. In this problem, it is either the picture rotated 90° clockwise or mirrored to the Y lines. If it mirrored, the effect would be X point become minus. But seeing the point B and C, the effect is
1. X and Y switched
2. X become minus
This effect is gained when you rotating 90° clockwise

In number 6, the picture moved 2 quadrants. It will be either rotated 180° or mirrored diagonally. The effect on the image is:
1. X and Y switched
2. Both X and Y become minus
This effect is gained if the shape was mirrored.

38. What is the surface area of a conical grain storage tank that has a height of 62 meters and a diameter of 24 meters? Round t
svetoff [14.1K]
1. The surface area of a cone S is S= \pi  r^{2}+  \pi rl, where r is the radius of the base and l is the slant height.

2. The slant height l is found as follows:

l^{2}= OC^{2}+ OB^{2}
l^{2}= 12^{2}+ 62^{2}=144+3844=3988

l= \sqrt{3988}=63.15

3. 

A=\pi r^{2}+ \pi rl=3.14(12)^{2}+3.14*12*63.15

= 452.16+2379.492 =2831.652 ( m^{2} )

 = 452.16+2379.492 =2831.652 ( m^{2} )

4. The answer is C

What is the equation in slope-intercept form of a line parallel to y=−2x+5 and passes through the point (4, 0)?
ser-zykov [4K]

Parallel lines have the same slope

The equation of the line is: y = -2x+8

The equation is given as:

y = -2x + 5

The slope intercept form of an equation is:

y = mx + b

Where:

m \to slope

By comparison,

m = -2

The line is said to be parallel to y = -2x + 5.

This means that the line has a slope of m = -2

The equation of the line is then calculated as:

y = m(x - x_1) + y_1

Where:

(x_1,y_1) = (4,0)

So, we have:

y = m(x - x_1) + y_1

Substitute values for m, x1 and y1

y = -2(x - 4) + 0

y = -2(x - 4)

Open brackets

y = -2x+8

Hence, the equation of the line is: y = -2x+8

See attachment for the graphs of y = -2x+8 and y = -2x + 5

Issouf claims that the scale factor is 1/2. which statement about his claim is correct?
love history [14]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

CB'=C'B'=2

B'B=6

CB=CB'+B'B=2+4=6

The scale factor of a figure is

k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}

k=\frac{C'B'}{CB}

k=\frac{2}{6}

k=\frac{1}{3}

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.
