Please help me I've been stuck on this one question and I can't find the answer to it.
For four Fridays in June, Grace earned $21.50, $29.75, $32.00, and $15.25 from babysitting.

In July, she earned $8 more for babysitting four Fridays than she did in June.

What is the increase in the mean for July compared to June?



Round the answer to the nearest penny.

Answers

Answer 1

Answer:

$2

Step-by-step explanation:

Its actually quite simple.

first find the mean for june.

add $21.50 + $29.75 + $32.00 + $15.25

that is equal to 98.5

then divide by 4.

that is 24.625

do not round to the nearest penny yet.

now you need to find the mean for july.

just add $8 to the total amount you made in june to find the total amount you made in july.

that is 106.5

then divide that by four because you worked four fridays in july as well.

that is 26.625.

finally you need to find the difference between 26.625 and 24.625.

26.625-24.625= 2

and ta-da!!!

the answer us $2.

your welcome. tell me if it is correct.

Given that ℓ1∥ℓ2 and the measure of ∠c = 44°, find the measures of angles a and b.
m∠a =
°
m∠b =
°

Answers

Answer:

<a = 44 degrees

<b = 136degrees

Step-by-step explanation:

From the given diagram;

<a = <c (alternate interior angle)

Since <c = 44 degrees, hence <a = 44 degrees

Also the sum of a and b is supplementary hence;

a + b = 180

44 + b = 180

b = 180 - 44

b = 136degrees

Hence m<b =136degrees

The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 illiterate people in the country.

Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today

Answers

Answer:

P(t)= 9000(0.4)^t

Step-by-step explanation:

Generally, we have an exponential function as follows;

P(t)= I(1 - r)^t

This case represents a decay ( decrease in value)

from what we have;

I represents the initial value, whereas r is the rate of change

From the question, we have that the change rate is the fraction 3/5

Writing this as a decimal, it is 0.6

substituting this back into the equation, we have;

P(t)= I(1-0.6)^t

P(t)= I(0.4)^t

I in this case is 9,000

So we have it that;

P(t) = 9000(0.4)^t

HELP Asap please!!!!!

Answers

Answer:

x should be 55

Step-by-step explanation:

the acute angle is 55 and we know that the whole horizontal is 180 so calculate 180-55 to find the obtuse angle which is 125. Then subtract 70 from that to isolate for x and you get 55.

They are a linear pair so they equal 180 so 55+70=125 and 180-125=55 so x= 55

The Invasion of the Lionfish


What was once just an attractive aquarium fish has recently become one of the biggest menaces in the Atlantic. The lionfish was accidentally introduced into the Atlantic Ocean in the 1990s. Because it has no natural predators, it has adapted quickly to its new home. The lionfish now threatens to destroy native fish populations in the Atlantic, Caribbean, and Gulf of Mexico.


The lionfish spreads quite rapidly. Lionfish spread faster than any other invading species. Experts have called the invasion in the Atlantic the worst marine invasion of all time. The lionfish's success comes from an ability to reproduce all year round. In addition, they are greedy eaters with a fondness for small fish and crustaceans. They will eat anything smaller than they are. Lionfish love the warm waters of the Gulf of Mexico. Since their first sighting, they have rapidly multiplied. In some locations, scientists estimate that lionfish populations exploded by 700 percent between 2004 and 2008 alone.


To combat the invasion, wildlife agencies have sponsored lionfish derbies. In these derbies, local scuba divers are invited to harvest lionfish. In addition, many states offer recipes for preparing and eating lionfish to encourage harvesting. Lionfish have to be handled carefully because of their venomous spines, but they are apparently delicious. Increasing the harvest of lionfish will help. However, scientists estimate that more than a quarter of the population would have to be taken every month to stop the growing population.


The lionfish has targeted our most fragile and important ecosystems. Scientists are working tirelessly to learn as much as they can about this predator. We may never be able to completely remove the threat, but many fishermen and seafood fans are hoping we can figure out how to control it.

Step-by-step explanation:

you have set them up so you can cross multiply.
