Answer:

Step-by-step explanation:

For what mileages will company A (which has a flat rate of $111) be less than the cost for company B

Company A < Company B

111 < 75 + 0.80m

solving

111 - 75 < 75 - 75 + 0.80m

36 < 0.80m

36/0.80 < 0.80m/0.80

as we are dividing by a positive number, we don't have to change the direction of the < sign.

45 < m

or m > 45

so if Ali intends to drive more than 45 miles, Company A's vehicle will be less expensive to rent

Nolan used the following procedure to find an estimate for StartRoot 18 EndRoot.

stiks02 [169]

Answer:

Nolan correctly identified the square numbers before and after 18.

The square roots of them are 4 and 5.

Clearly, square root of 18 should lie between 4 and 5 only.

He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.

Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.

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

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
