Find the missing right triangle side lengths in the models of the Pythagorean Theorem below
Answer: 24, 10, 26 and 4.6, 5, 6.7
Step-by-step explanation: for the first triangle the square with the area 576 has side lengths of 24 because 24 is the square root of 576, the square with the area 676 has a side length of 26 because 26 is the square root of 576, and we already know the side lengths of the third triangle are 10 for the second triange we know the side length of the square with the area 21 is about 4.6 because √21 ≈ 4.6 and the square with the area 25 the side length is 5 because √25 = 5 and the last square the side length is 6.7 because √46 ≈ 6.7

PLEASEEEE HELPP!!!! PLEASEE HELP NOW PLEASE!!
Answer:
7.19
Step-by-step explanation:
Answer
$7.20 if you round up. Not rounded is $7.198 or just $7.19
Step-by-step explanation
First, get original price which is $9 rounded.
Then, multiple by percent off which would be .20 or .2. Don't get this confused with 2% off which is .02.
After multiplying, you should get the answer of $1.80, this is 20% of $9.00. So if the product was 20% off, you would subtract. This gives you the final answer of $7.20

Answer:
x =77 degrees
Step-by-step explanation:
All the angles added up equal 180 degrees so:
2x + 26 = 180
Subtract 26 from both sides:
2x = 154
Divide both sides by 2:
x =77 degrees
Answer:
please mark brainliest
2x + 26 = 180
2x=180-26= 154
x=154/2

given a storm has a destruction area in the shape of a square, give the total area affected if the side lengths of the square were 315.2
Answer:
to find area, multiply the two sides together. since it tells us that this is a square we can assume both sides are the same length (315.2). multiply 315.2 and 315.2, and you get 99,351.04.
Solve 15 = 1/3x
x = ?
Hey there!
The answer to your question is x = 45
To solve this, we want to get x with a coefficient of 1 by itself on one side of the equal sign, and right now it's coefficient is 1/3. We can get a coefficient of 1 by multiplying both sides of the equation by 3.
15(3) = 1/3x(3)
45 = x

What is \frac{\sqrt{7}}{\sqrt{11}} in simplest radical form?
Pls i really need help on this :/
Answer: [tex]\frac{\sqrt{77}}{11}[/tex]
===================================================
Explanation:
Assuming you want to rationalize the denominator, we multiply top and bottom by sqrt(11) like so
[tex]x = \frac{\sqrt{7}}{\sqrt{11}}\\\\x = \frac{\sqrt{7}*\sqrt{11}}{\sqrt{11}*\sqrt{11}}\\\\x = \frac{\sqrt{7*11}}{\sqrt{11*11}}\\\\x = \frac{\sqrt{77}}{\sqrt{121}}\\\\x = \frac{\sqrt{77}}{11}\\\\[/tex]
In the third step, I used the rule that sqrt(A)*sqrt(B) = sqrt(A*B).

Answer these questions about killer whales:
What do killer whales look like? Be very specific, colors, size, length, spots, stripes, camouflage...etc.
What are some facts about killer whales? List at least 5.
I will give brainliest, thanks, friend request, and 5 stars to the best answer.
Answer:
Adult male killer whales are larger overall than their female counterpart including features such as pectoral flippers, dorsal fins, tail flukes, and girth. The largest recorded male killer whale was 9.8 m (32 ft.) in length and weighed 10,000 kg (22,000 lbs.) The largest recorded female was 8.5 m (28 ft.) and weighed 7,500 kg (16,500 lbs.). Data from Icelandic killer whales (North Atlantic type 1) indicate that an average-size male is about 5.8 to 6.7 m (19 to 22 ft.) long, while females averaged 4.9 to 5.8 m (16 to 19 ft.) long. Killer whale sizes vary significantly between different ecotypes.
Male Antarctic type A killer whales can reach lengths of 9.2 m (30 ft.) making them the largest known killer whales. The smallest killer whale ecotype is the Antarctic type C killer whales in which adult females average 5.2 m (17 ft.) and adult males average 5.6 m (18 ft.) in length and can reach a maximum of 6.1 m (20 ft.). At SeaWorld, average size for adult males is 6.6 m (21.7 ft.) Two of the largest adult male killer whales at SeaWorld weigh 4,340 kg (9,570 lbs.) and 5,380 kg (11,860 lbs.).
At SeaWorld, average size for females is 5.5 m (18 ft.) and 2,442 kg. (5,384 lbs.) SeaWorld's adult female whales range in weight from 2,313 kg (5,100 lbs.) to 3,719 kg (8,200 lbs.). The general body shape of a killer whale is roughly cylindrical but tapering at both ends. This characteristic fusiform shape is quite energy efficient for swimming. Killer whales are black and white, with a gray patch called a "saddle" or a "cape" on the back, just behind the dorsal fin. A killer whale's forelimbs are adapted for swimming. A killer whales uses its rounded, paddlelike pectoral flippers to steer and, with the help of the flukes, to stop. A killer whale's pectoral flipper contains 5 digits much like the fingers on a human hand. Each lobe of the two-lobed tail is called a fluke. Flukes are flat pads of tough, dense, fibrous connective tissue, completely without bone or cartilage. Like the flukes, the dorsal fin is made of dense, fibrous connective tissue, without bones or cartilage. A killer whale has an indistinct rostrum (snout-like projection).
A single blowhole on top of the head is covered by a muscular flap. A killer whale breathes through its blowhole. The blowhole is relaxed in a closed position, and the flap provides a water-tight seal. To open its blowhole, a killer whale contracts the muscular flap.
A killer whale's eyes are on each side of its head, just behind and above the corner of its mouth, and in front of its white eyespot.
A killer whale's large teeth are conical and interlocking. Toothed whales have only one set of teeth; they are not replaced once lost. The number of teeth varies among individuals. There are usually 10 to 14 teeth on each side of each jaw (40 to 56 teeth total). A killer whale's blubber layer lies beneath the dermis and measures from 7.6 to 10 cm (3 to 4 in.) thick. Blubber is a layer of fat reinforced by collagen and elastic fibers. In general, blubber has a number of important functions: A killer whale's dermis (skin) is smooth. The outer layer continually and rapidly renews itself, and the old skin sloughs off. The increased skin cell turnover increases swimming efficiency by creating a smooth body surface which reduces drag.
Facts:
1) The name killer whale derives from their original name ‘whale killers’ given to them by sailors who saw them hunting whales. Over time, the name eventually switched around. The name ‘orca‘ comes from their Latin species name Orcinus orca, where orcinus translates to mean ‘Kingdom of the dead’.
2. Despite their name, killer whales are actually a dolphin – the largest species of oceanic dolphin!
3.Whilst they can and do eat prey such as finfish and marine mammals, New Zealand orca have become specialised at hunting sharks and rays. They can often be seen up around rocky reefs and in the shallows of beaches while they are hunting.
4.The average life span of an orca is not too dissimilar to a human, at 50-80 years for females and slightly less for males at 29-60 years.
5.Orca can be seen in every ocean on the earth. They are one of the most successful marine mammals in terms of range.
