7. The total cost to rent a truck is $100 and $0.20 per km.

eduard

Answer:

. The total cost to rent a truck is $100 and $0.20 per km. a. Determine an algebraic model for the relationship between total cost and distance driven. Use Cto represent total cost ($) to rent the truck and d to represent distance driven (km). C=$100+$0.20d b. Create a graphical model. You may use the Linear Graphing Tool or Desmos to create your graphical model. Take a screenshot of your graph and paste it here.

Thank you

it takes a hospital dietitian 15 minutes to drive from home to the hospital, a distance of 14 miles, what is the dietitian's rat

scoundrel [369]

Hi. Good?

To solve is to use the formula:

D = v.t

14 = v. 15
v= 14/15
v = 0,9333..mpm

15m = 900s

14 = v. 900
v=14/900
v=0,01555...mps

I put the result in miles per minute and miles per second.

Thanks, I hope I have helped.

Find the least common multiple (LCM) of 8y^6+ 144y^5+ 640y^4 and 2y^4 + 40y^3 + 200y^2.

Mice21 [21]

Answer:

LCM = $8y^{4}(y+ 10)^{2}(y + 8)$

Step-by-step explanation:

Making factors of $8y^{6}+ 144y^{5}+ 640y^{4}$

Taking $8y^{4}$ common:

$\Rightarrow 8y^{4} (y^{2}+ 18y+ 80)$

Using factorization method:

$\Rightarrow 8y^{4} (y^{2}+ 10y + 8y + 80)\\\Rightarrow 8y^{4} (y (y+ 10) + 8(y + 10))\\\Rightarrow 8y^{4} (y+ 10)(y + 8))\\\Rightarrow \underline{2y^{2}} \times 4y^{2} \underline{(y+ 10)}(y + 8)) ..... (1)$

Now, Making factors of $2y^{4} + 40y^{3} + 200y^{2}$

Taking $2y^{2}$ common:

$\Rightarrow 2y^{2} (y^{2}+ 20y+ 100)$

Using factorization method:

$\Rightarrow 2y^{2} (y^{2}+ 10y+ 10y+ 100)\\\Rightarrow 2y^{2} (y (y+ 10) + 10(y + 10))\\\Rightarrow \underline {2y^{2} (y+ 10)}(y + 10) ............ (2)$

The underlined parts show the Highest Common Factor(HCF).

i.e. HCF is $2y^{2} (y+ 10)$ .

We know the relation between LCM, HCF of the two numbers 'p' , 'q' and the numbers themselves as:

$HCF \times LCM = p \times q$

Using equations (1) and (2): $\Rightarrow 2y^{2} (y+ 10) \times LCM = 2y^{2} \times 4y^{2}(y+ 10)(y + 8) \times 2y^{2} (y+ 10)(y + 10)\\\Rightarrow LCM = 2y^{2} \times 4y^{2}(y+ 10)(y + 8) \times (y + 10)\\\Rightarrow LCM = 8y^{4}(y+ 10)^{2}(y + 8)$

Hence, LCM = $8y^{4}(y+ 10)^{2}(y + 8)$

Linda received 4/5 of the votes in the votes in the election for student council president.what percent of votes did Linda recei

Mariana [72]

Answer:

80% 0.8

Step-by-step explanation:

To find the percentage out of a fraction you would divide 4÷5 to get 0.8, the decimal answer, then to turn that to a percent you would move the point two places to the right to get 80%.
