Pat rents a car. The car costs $30 per day with an additional charge of $0.10 per mile. He rented it for 7 days and drove 350 miles. What is the cost for renting the car? Write an equation and solve.

245

Step-by-step explanation:

30 times 7 is 210 and 350 times 19 cents is 35

The equation is y = 30d + 0.10m. The cost is $245.

Step-by-step explanation:

Plug in the values for the equation. The equation will become y = 30(7) + 0.10(350). Solve to get y = 210 + 35. This equals y = 245.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
