Deffense [45]

Answer:

(0, 9 ) and (- 4, 1 )

Step-by-step explanation:

To determine which ordered pairs lie on the graph substitute the x- coordinate of the point into the right side of the equation and compare the value obtained with the y- coordinate

(- 20, - 49 )

2x + 9 = (2 × - 20) + 9 = - 40 + 9 = - 31 ≠ - 49

(1, 10 )

2x + 9 = (2 × 1) + 9 = 2 + 9 = 11 ≠ 10

(0, 9 )

2x + 9 = (2 × 0) + 9 = 0 + 9 = 9 ← point lies on graph

(- 4, 1 )

2x + 9 = (2 × - 4) + 9 = - 8 + 9 = 1 ← point lies on graph

(- 3, 40 )

2x + 9 = ( 2 × - 3) + 9 = - 6 + 9 = 3 ≠ 40

PLEASE I NEED HELP

Answer: 0.25 feet


Step-by-step explanation:

Given: Jonathon has paper strips that are all equal in length.

Let x be the length of each paper strip.

Since John lines them up end to end, the length of the line of paper strips= 3 feet

Also total strips used= 12

Therefore, length of line of strips=12x=3\ feet

\\\Rightarrow\ x=\frac{1}{4}\ feet\\\Rightarrow\ x= 0.25\ feet

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.

The area of the surface of a sphere is described by the formula S=4(3.14)r^2. The earth has a radius of 3960 miles and dry land
Stella [2.4K]

Answer: 57,512,581.63miles^2

Step-by-step explanation:

Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:

S=4(3.14)r^2\\S=4(3.14)(3,960miles)^2\\S=196,960,896miles^2

The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by \frac{29.2}{100}=0.292

Threfore, the area of dry land is the following:

S_{land}=(0.292)(196,960,896miles^2)=57,512,581.63miles^2
