During the school year, each student planted 2 x 10^2 trees as part of a community service project. If there are 3.5 x 10^3 stud

amm1812

Answer:

Total number of trees planted = $7\times 10^{5}$ trees

Step-by-step explanation:

Trees planted by each student = $2\times 10^2$

Total number of students = $3.5\times 10^3$

Using unitary method to find total number of trees planted by all the students in school.

1 student plants = $2\times 10^2$ trees

$3.5\times 10^3$ student would plant = $(2\times 10^2)\times (3.5\times 10^3)$

We apply the product rule of exponents to multiply $[a^xa^y=a^{x+y}]$

⇒ $(2\times 3.5)\times(10^2\times 10^3)$

⇒ $7\times 10^{2+3}$

⇒ $7\times 10^{5}$ trees

Total number of trees planted = $7\times 10^{5}$ trees

Answer:

SNITCHY SNATCH

Step-by-step explanation:

I actually don't know how to show how to graph it. Sorry. But I can give a few coordinates. For y < 1/3x + 3: (-1,2 2/3) (0,3) (1,3 1/3). For y > -2/3x - 3: (-1,-2 1/3) (0,-3) (1,-3 2/3).

Complete the statement below to explain how this model shows that 1/3÷1/5=5/3

Galina-37 [17]

To divide by a fraction, multiply by the reciprocal of that fraction.

1/3 • 5/1 or 1/3 • 5

Calculate the product straight across.

1/3 • 5/1 = 5/3
