20.

Add a zero to both numbers. Now it is 20 and 100. Percents are out of 100, so it would be 20.

Place the indicated product in the proper location on the grid.
marishachu [46]

Answer:

See explanation

Step-by-step explanation:

1.

(a+b)(a^2-ab+b^2)=a^3-a^2b+ab^2+a^2b-ab^2+b^3=a^3+b^3

2.

(1-7x)(1+9x)=1+9x-7x-63x^2=-63x^2+2x+1

3.

(x+y+3)(x+y-4)=x^2+xy-4x+xy+y^2-4y+3x+3y-12=x^2+2xy+y^2-x-y-12

4.

(a-b)(a^2+ab+b^2)=a^3+a^2b+ab^2-a^2b-ab^2-b^3=a^3-b^3

5.

(m^3n+8)(m^3n-5)=(m^3n)^2-5m^3n+8m^3n-40=m^6n^2+3m^3n-40

6.

(4-(3c-1))(6-(3c-1))=(4-3c+1)(6-3c+1)=(5-3c)(7-3c)=35-15c-21c+9c^2=9c^2-36c+35

7.

(ab-9)(ab+8)=(ab)^2+8ab-9ab-72=a^2b^2-ab-72

8.

(a+b-c)(a+b+c)=a^2+ab+ac+ab+b^2+bc-ac-bc-c^2=a^2+b^2-c^2+2ab

9.

(a+3)(a-2)=a^2-2a+3a-6=a^2+a-6

10.

(3m^3-y)(3m^3-y)=(3m^3)^2-3m^3y-3m^3y+y^2=9m^6-6m^3y+y^2

11.

(2x-3y)(4x-y)=8x^2-2xy-12xy+3y^2=8x^2-14xy+3y^2

12.

(x^2+2x-1)(x^2+2x+5)=x^4+2x^3+5x^2+2x^3+4x^2+10x-x^2-2x-5=x^4+4x^3+8x^2+8x-5

13.

(4x-3y+5)(x+2y-3)=4x^2+8xy-12x-3xy-6y^2+9y+5x+10y-15=4x^2+5xy-6y^2-7x+19y-15

morpeh [17]
They would meet after 4 hours, as 65 x 4 = 260. And 60 x 4 = 240. If you add these, they become a value of 500. This also answers the 2nd question ; 65x + 60x = 500.

The bottom of Ignacio's desktop is
Verizon [17]

Answer:

The inequality to determine the number of rotations is given by

 r ≤ 5.25

Therefore the maximum number of rotations possible is 5.

Step-by-step explanation:

i.) The bottom of Ignacio's desktop is  74.5 cm from the floor.

ii.) The tops of his legs are 49.3 cm from the floor.

iii.) the difference between the bottom of Ignacio's desktop and the top of his legs = 74.5  - 49.3 = 25.2 cm.

iv.) Each clockwise rotation of the knob on the chair raises Ignacio's legs by 4.8 cm.

v.) let the number of clockwise rotations be r.

vi.) therefore the inequality to determine the number of rotations is given by

  4.8r ≤ 25.2     therefore r ≤ 25.2/4.8    therefore r ≤ 5.25
