The page numbers of book are 203 and 204.

Step-by-step explanation:

Let,

the two consecutive integers are;

x, x+1

Sum of integers = 407

$x+(x+1)=407\\x+x+1=407\\2x=407-1\\2x=406\\$

Dividing both sides by 2

$\frac{2x}{2}=\frac{406}{2}\\x=203$

Therefore,

the two integers are;

x = 203

x+1 = 203+1 = 204

The page numbers of book are 203 and 204.

Match the solid figure to the appropriate formula.

AlekseyPX

1. $L \cdot A=\pi r l$ - Cone

2. $V=\frac{4}{3} \pi r^{3}$ - Sphere

3. $T \cdot A=2 \pi r h+2 \pi r^{2}$ - Cylinder

4. $V=\frac{1}{3} B h$ - Pyramid

5. $L . A=p h$ - Prism

Solution:

1. $L \cdot A=\pi r l$

Lateral surface area of cone = $\pi r l$

where r is the radius of the cone and l is the slant height of the cone.

2. $V=\frac{4}{3} \pi r^{3}$

Volume of sphere = $\frac{4}{3} \pi r^{3}$

where r is the radius of the sphere.

3. $T \cdot A=2 \pi r h+2 \pi r^{2}$

Total surface area of cylinder = $2 \pi r h+2 \pi r^{2}$

where r is the radius of the cylinder and h is the height of the cylinder.

4. $V=\frac{1}{3} B h$

Volume of pyramid = $\frac{1}{3} B h$

where B is the base area of the pyramid and h is the height of the pyramid.

5. $L . A=p h$

Lateral surface area of prism = $p h$

where p is the perimeter of the base and h is the height of the prism.

Answer:

5 units. Since they have the same y coordinate the x coordinate determines the distance from each other. In the case 9-4=5.

How do i draw a decimal for example 0.26?

elixir [45]

First, you need convert the decimals into fraction

0.26 = 26/100 = 13/50

The next step would be drawing 50 small boxes on a piece of paper. Make it colorless.

The final stap would be giving 13 out of those 50 boxes with different color (such as black), and you're done

The height of a distance marker is 8 2/13 feet. 4/5 of the pole is painted white and rest is painted blue. How much of the pole

Mashcka [7]

1) Convert the mixed number 8 and 2/13 into a fraction:

8 and 2/13 = 8 + 2/13 = (8*13 + 2) / 13 = 106 / 13

2) Calculate 4/5 of 106 / 13

(4 / 5) * ( 106 / 13) = (4*106) / (5*13) = 424 / 65

That is (390 + 34) / 65 = 390/65 + 34/65 = 6 + 34/65 is painted white

3) Calculate the rest

(1/5) * (106 / 13) = 106 / 65 = 1 + 41/65 is painted blue
