Asoftware coder can type 79 words per minute. she works 5 eight hour days each week (not including
breaks). how many words does she type in a week?
a 189,600 words
b. 33 words
c.3.160 words
d. 76,950 words

189600

Step-by-step explanation:

If she can type 76 words per minute,

then to find the number of words she can type per hour, we simply multiply 79 by 60( because 1 hour = 60minutes)

79 × 60 =4740

Therefore she can type 4740words per hour

Now we proceed, she works 5 days in a week, and she works 8 hours per day

we need to get the total number of hours she works in a week, to get that, we simply multiply 8 by 5

8 × 5 = 40

which implies she works 40hours in a week

So, to get the total number of words she can type in a week,

we simply multiply 4740 × 40 = 189,600 words.

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
