Marianna [84]
You must find the relative rates of both workers...

T=f/3 and J=f/2  so if they work together to clear the field then:

ft/3+ft/2=f  make all terms have a common denominator of 6

(2/2)(ft/3)+(3/3)(ft/2)=(6/6)f

2ft/6+3ft/6=6f/6  multiply both sides by 6

2ft+3ft=6f  divide both sides by f

2t+3t=6  combine like terms on left side

5t=6  divide both sides by 5

t=6/5 hr

t=1 1/5 hr

t=1 hr 12 min

Stephanie has a homeowners insurance policy for her $355,000 home with an annual premium of $0.42 per $100 of value and a deduct
frosja888 [35]

Answer:

$0.28 per 100 of value (B)

Step-by-step explanation:

Stephanie has a homeowner insurance policy of $355,000

Annual premium = $0.42 per 100

There is a deductible of $500

Stephanie has an annual out of pocket expense of

[($355,000/100) x $0.42] + $500 = $1,991

From the question, Stephanie now wants a new deductible amount of 1000.

Let X be the new annual premium

[(355,000X) / 100] + 1000 = 1991

3550X + 1000 = 1991

3550X = 1991 -1000

3550X = 991

X = 991/3550

X = 0.2791

X = 0.28 ( approximately)

The new annual premium is $0.28 per 100 of value

Question 3 of 18
iren [92.7K]

Answer:

D. 0.74.

Step-by-step explanation:

It is a BINOMIAL trial, which means that there are only two outcomes: either success, or failure.

So, if the probability of success is 0.26, the probability of failure will be 1 - 0.26 = 0.74.

Hope this helps!

A toy rocket was shot into the air. The graph below represents the height over the time of the rocket. Which of the following ar
Ludmilka [50]

Answer: Option 'B' and 'C' are correct.

Step-by-step explanation:

Since we have given that

A  rocket was fired into the air.

The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.

And it took the rocket 3.5 seconds to reach its maximum height.

and the rocket landed after 6.9 seconds, So option 'D' is false which states  The rocket landed after 34 seconds.

The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.

Hence, Option 'B' and 'C' are correct.
