Answers

Answer: $69

Step-by-step explanation: For every hour ray works over 40 hours, he makes an additional $7.50. According to part B, Ray calculated incorrectly that he earned $45 of additional pay. His error when he calculated incorrectly his overtime pay was that he didn't mulitply correctly, and that gave him the andwer of $45. So therefore, Ray's paycheck for working 46 hours was $69. How I found out my answer I did 150% times 46 which gave me 6,900. After that I divided 6,900 by 100 which gave me 69. If we wanna check our answer we can always divide 69 and 46 hours and get 150%. So In Conclusion, Ray would make more oney working 32 hours a week, and then 46 the next week. We also found this out, because working 32 hours one week ray makes $48, but when he works 46 hours a week, ray makes $69 and when adding those together it makes much more than 40 hours a week for two weeks.

A barometer falls from a weather balloon
at a height of 14,400 ft. If the equation
for height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the
barometer to hit the ground?

Answers

Answer:

Step-by-step explanation:

h(t) = -16t² + 14400

0= -16t² + 14400

(1/-16)×-14400=-16t²(1/-16)

900=t²

[tex]\sqrt{900} =\sqrt{t^{2}}[/tex]

30=t

Hence, the time taken in seconds for barometer to hit the ground is 30.

A barometer falls from a weather balloon from a height of 14400, this means that the initial height is 14,400 ft.

How many seconds will it take for the barometer to hit the ground?

The initial height of a barometer is 14,400 ft.

After the barometer falls from a weather balloon it hits the ground and final height is 0.

So, the equation h(t)= -16[tex]t^{2}[/tex]+ initial height

putting h(t)=0 which is the final height and initial height=14,400 we get,

0=-16[tex]t^{2}[/tex] +14,400

16[tex]t^{2}[/tex]=14,400

t=[tex]\sqrt{14,400/16}[/tex]

[tex]t^{2}[/tex]=900

t=[tex]\sqrt{900}[/tex]

t=30

Hence, the time taken by barometer to hit the ground is 30 seconds.

Answers

Answer:

u · v = - 13

Step-by-step explanation:

dot product of u = 〈3, - 4〉and v =〈- 7, - 2〉

(3î - 4j) • (- 7î - 2j) = - 21 + 8 = -13

The dot product of u = 〈3, - 4〉 and v =〈- 7, - 2〉 as u · v = - 13.

How to find the dot product of two function?

The dot product of the two function u and v can be calulated as

u · v = (xî + yj) • (aî + bj)

The dot product of u and v is a scalar because dot product is always a scalar.

The dot product of u = 〈3, - 4〉 and v =〈- 7, - 2〉

u · v = (xî + yj) • (aî + bj)

= (3î - 4j) • (- 7î - 2j)

= - 21 + 8

= -13

A local Hamburger shop sold a combined total of 553 hamburgers and cheeseburgers on Saturday. They were 53 more cheeseburgers sold and hamburgers. How many hamburgers were sold on Sunday?

Answers

Answer:

250 hamburgers were sold on Sunday

Step-by-step explanation:

Let there are x hamburgers and y cheeseburgers sold on Sunday.

ATQ,

x + y = 553 .....(1)

There were 53 more cheeseburgers sold than hamburgers.

y = 53 + x ....(2)

Put the value of y from equation (2) in equation (1).

x + (53 + x) = 553

2x+53 = 553

2x = 500

x = 250

Put the value of x in equation (2).

y = 53 + 250

y = 303

Hence, 250 hamburgers were sold on Sunday
