Patrick's gross earnings for the week are $1592.45. His deductions comprise 26% of his total compensation. What is his net pay? Enter your answer rounded to the nearest cent, such as: $4253.64.
Patrick's net income will be equal to $1178.41.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Patrick's gross earnings for the week are $1592.45. His deductions comprise 26% of his total compensation.
Patrick's net income will be calculated as below:-
26% of $1592.45 = 1592.45 x ( 26 / 100 ) = 414.037
Subtract the deduction from the gross amount:-
Net income = 1592.45 - 414.037 = $1178.41
Therefore, Patrick's net income will be equal to $1178.41.

standard form of 1.23 * 10 to the 11th power
1. Convert to decimal notation
The exponent is 11, making it 10 to the power of 11. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 11 time(s):
[tex]1.23 -> 123000000000[/tex]need an answer, please need an answer, please

If a fair coin is tossed twice the possible outcomes are HH, HT, TH or TT, where HH means both tosses are heads and HT means that the first toss is a head and the second toss is a tail, etc. Since the coin is fair, a 50-50 chance of getting a head or a tail, we assign a probability of 1/4 to each of the four outcomes. Assuming that a fair coin was tossed twice, find the probability that both tosses were heads given that at least one of the tosses was a head. Round your answer to 4 decimal places.
The conditional probability value rounded to 4 decimal places is : 0.2500
The relation can be used to find the conditional probability of events given :
P(HH | Atleast 1 head) = P(HHn(Atleast 1 H)) / P(Atleast 1 H)
P(Atleast 1 H) = P(HT + TH + HH)
P(Atleast 1 H) = P(HT + TH + HH) = 3(0.25) = 0.75
P(HHn(Atleast 1 H)) = P(HH) × P(Atleast 1 H) = 0.25 × 0.75 = 0.1875
Therefore, the conditional probability can be expressed as :
P(HH | Atleast 1 head) = 0.1875 / 0.75 = 0.25Therefore, P(HH | Atleast 1 head) is 0.25

What is the equation of the blue line?
Answer:
y = 4x - 3
Step-by-step explanation:
When writing an equation of a line, keep in mind that you always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:
1. 2 sets of ordered pairs (x, y)
2. Slope (m)
3. Y-intercept (b)
First, we need to choose 2 points from the graph to solve for the slope:
Let (x1, y1) = (0, -3)
(x2, y2) = (1, 1)
Use the following slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
Substitute the values of the coordinates into the formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - (-3)}{1 - 0} = \frac{1 + 3}{1} = \frac{4}{1} = 4[/tex]
Therefore, the slope (m) of the line = 4.
Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, -3) is the y-intercept. Hence, the y-intercept (b) = -3.
Given our slope, m = 4, and the y-intercept (b) = -3, the linear equation is:
y = 4x - 3

At a little-known vacation spot, taxi fares are a bargain. A 28-mile taxi ride takes 42 minutes and costs $16.80. You want to find the cost of a 50-mile taxi ride. What unit price do you need?
Answer:
Unit Cost = 0.6
Cost for 50 mile taxi ride = $30
Step-by-step explanation:
We are given the following information in the question:
Length of taxi ride = 28 miles
Time taken by taxi ride = 42 minutes
Cost of taxi ride = $16.80
We have to find cost of a 50 mile ride.
In order to do so, we have to find the unit cost of distance covered by ride which is the unit cost per mile of the ride that is the cost for 1 mile of taxi ride.
Our Formula:
Unit Cost = Cost for 1 mile of taxi ride = cost of taxi ride / distance covered by taxi ride
Using the values given we can use the formula so
unit cost = 16.80 / 28 = 0.6
Cost of 50 mile taxi ride
0.6 x 50 = 30

An otter is swimming at - 4.2yo relative to the surface of the water. It dives 6.0 yds desper. After thedive, what is the otter's elevation relative to the surface of the water?.
Answer:
Where to look: Any waterway you’re near! River otters are happy in fresh, brackish and salt water. They’re often seen in coastal areas near the mouths of rivers and creeks. They’re often seen in marshes and wetlands. They’re a little harder to see in vegetated rivers but keep looking, especially when boating. They’re often found in lakes…look where the fish are. In-crowd hint: Check out our otter spotter map to see where they’re often reported!
When to look: River otters are most often seen at dusk and dawn, but can be seen at any hour of the day or night.
What do I look for? Look for large ripples on the surface of the water, lots of bubbles and a 3 to 4 foot-long animal with a long thick tail. The tail is about a third of the body length of the otter. Otters are dark and sleek in the water. Otters have a large black hairless nose (rhinarium).
How do otters swim and move? In the water, river otters do not swim on their backs like sea otters. They can swim along with just their heads showing, they can dive and roll and they often stay underwater for up to 15 or 20 seconds. They also “periscope,” meaning raise their necks far out of the water to see farther. When swimming, they usually carry their bodies just under the surface. They’re very elusive and can “disappear,” into the water, brush, rocks or under overhanging vegetation.
On land, river otters are agile, can run quickly and climb trees. They’re small and narrow-bodied, with longer back legs than forelegs, so they move with a humping gait. They’re often seen running across beaches, or along paths near water.
There’s a superb Otter/Beaver/Muskrat article with photos and descriptions here.
SEA OTTER (Enhydra lutris)
In California, sea otters are most often seen around Monterey Bay and Elkhorn Slough. Occasionally we see them in the SF Bay Area. Sea otters are twice the size of river otters, and are never far from the ocean. They have enormous back flippers, and often swim on their backs with their big flippers sticking out of the water. Their tails are short and not as muscular as river otters. They are clumsy on land.
This video by Tom Reynolds shows sea otters first, then river otters. The differences will become obvious!
MUSKRAT (Ondatra zibethicus)
Muskrats are rodents, about 18 inches long, with a thin tail. Like beavers, they swim straight across the water, with their backs at or slightly above water level, without diving and rolling, until it’s time to submerge.
Typical muskrat swimming; note the thin long tail.
Here’s a nice muskrat video.
BEAVER (Castor canadensis)
Beavers are rodents with large orange teeth. They have a very distinctive large, flat tail which slaps the water when they’re startled. Beavers are burly animals, and weigh about twice as much as river otters. Their fur is clumpy when wet. Like muskrats, their bodies are usually at or slightly above water level when they swim.
Here’s a gorgeous beaver, look at that tail!
Here’s our friend Heidi of Worth A Dam in a wonderful video showing the difference between otters and beavers.
HARBOR SEAL (Phoca vitulina)
Harbor seals are seen in the ocean, bays and marshes. They’re quite fat-looking, because they carry a large layer of fat on their bodies to keep them warm in cold waters. Harbor seals have very large heads and big dark eyes. They startle easily, and dive under water with an enormous splash if you surprise them while kayaking. They’re grayish, with mottled fur, sometimes paler gray toward white.

The tape diagram represents the ratio of the time you spend tutoring to the time your friend spends tutoring. You tutor for 3 hours. How many hours does your friend spend tutoring?
You
Friend
Answer:
15 Hours
Step-by-step explanation:
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
Therefore, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours
