A Shape Is Made Of 9 Right Triangles Of Equal Size And Three Identical Rectangles.Each Rectangle Measures

Answers

Answer 1

Answer:

The area of the figure is 157.5 square millimeters.

Step-by-step explanation:

Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:

Area of a rectangle: base x height

Area of a triangle: (base x height) / 2

7x3 = 21 = Rectangle area

7x3 / 2 = 10.5 = Triangle area

21 x 3 + 10.5 x 9 = 157.5

Thus, the area of the figure is 157.5 square millimeters.

(50pts) The distance covered and the time taken by a car are plotted in a graph.


a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.

Answers

Answer:

a=2

b=40m

c=2m/s

Step-by-step explanation:

slope is rise over run so 10/5 simplified is 2/1 or 2

for b just look at the graph at the 20th second

for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

what strategy can be used to transform a quadratic function in vertex form to standard form

Answers

Hello, I Am BrotherEye

Answer:

This Transparent inquisition can be solved Below

Use transformations to graph a quadratic function in vertex form. A quadratic function in standard form, f(x) = ax² + bx + c, can be changed into vertex form by completing the square. The vertex form of a quadratic function is f(x) = a(x – 5)2 + k, where the vertex of the function is (h, k).

Step-by-step explanation:

Vertex form to standard form converter

Write the parabola equation in the vertex form: y = a*(x-h)² + k ;

Expand the expression in the bracket: y = a*(x² - 2*h*x + h²) + k ;

Multiply the terms in the parenthesis by a : y = a*x² - 2*a*h*x + a*h² + k ;

Best Of Luck

The total bill for drinks and a pizza for three people is $14.90 before tax. The group wants to leave a 15% tip on the cost of the food, not including tax. What will be the amount of the tip?

Answers

Answer:

$2.24

Step-by-step explanation:

Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.

The tip would be 2 dollars and 24 cents. ($2.24).

(5y+1)²-4(y-1)² how to solve it​

Answers

Answer:

[tex](5y + 1)^{2} - (2(y - 1))^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y - 1 ).

[tex](5y + 1) ^{2} - (2(y - 1)) ^{2} [/tex]

2) Use multiplication Distributive Property: (xy)^a = x^a y^a.

[tex](5y + 1)^{2} - {2}^{2} (y - 1 {)}^{2} [/tex]

3) Simplify 2² to 4.

[tex](5y + 1 {)}^{2} - 4(y - 1 {)}^{2} [/tex]

4) Rewrite it in the form a² - b², where a = 5y + 1 and b = 2(y-1).

[tex](5y + 1 {)}^{2} - (2(y - 1))^{2} [/tex]

Therefor, the answer is ( 5y + 1 )² - (2( y - 1 ))².

Making the Most of MucusJust the name itself will make you giggle. It's a great word that conjures visions of slime and unpleasantness. It is perhaps the most annoying part of having a cold or allergies. Mucus, however, plays a very important role in defense of our bodies and our health. In fact, it's high time mucus got a lot more respect.First, there are some amazing facts about mucus that are worthy of respect. Humans produce about a liter of mucus every day, whether they are sick or not. Bony fish and some invertebrates (snails or slugs) also have mucus cells on the outside of their body. This external mucus creates a protective coating that prevents predators' toxins from doing harm. Humans produce mucus to protect our stomachs, our lungs, and several other systems.We tend to not like mucus because it is a considered a symptom or sign that something is wrong. We usually only see it when we are sick, and so we tend to dislike it. According to Michael M. Johns, III, MD, however, "mucus is incredibly important for our bodies." Johns, an assistant professor at Emory University, calls mucus "the oil in the engine" of our bodies. Without mucus, our engines, or bodies, would freeze up and stop working properly.Furthermore, mucus is not just the nasty gunk you see when you are sick. It lines the tissues in your mouth, your nose, throat, and lungs. It also is crucial in protecting your digestive system. Mucus puts a protective coating over the surfaces of these tissues, keeping them moist. Most of the time we don't notice mucus is making our lives better. It does its job quietly, making everything run smoothly, keeping our inner tissues soft and flexible enough to fight off invaders.Occasionally, though our mucus-making membranes go into overdrive. If you eat a hot pepper, your mucus membranes in your mouth and throat start producing extra mucus to protect you. If you come into contact with pollen, you may get a runny nose and start sneezing and coughing. When these things happen, your mucus systems start making more fluids to wash away the irritating particles. Mucus also has some antibodies that increase our ability to fight off bacteria and viruses.It's hard to appreciate what is essentially slime, but we have mucus for some very good reasons. It helps to keep us healthy and lets us know when our bodies are under attack. We would be wise to respect what our bodies do to keep us safe. So the next time you find yourself reaching for a tissue, remember mucus is your friend and ally.What's in a Name?Mucus is a great word, not only because it gives name to an important bodily function, but also because it is one of those words that simultaneously makes you feel grossed-out and giggly. Other words for this powerfully important human-health tool include slime and phlegm. Slang words for mucus include boogers and snot. All of these words have the same giggle-power, simply from the combination of consonants and vowels. By the way, mucus is an old word; it's been around since the mid-1600s and has roots back to Latin (mucere, to be moldy or musty) and Greek (myxa, mucus). While you may assume that words like snot and boogers are relatively new slang terms, they are not. Snot dates to 1560 and comes from an Old English word, gesnot, and has the same root as the word snout. The word booger is not quite as old but has been in use since the 1890s.Read this sentence from the main text:It's hard to appreciate what is essentially slime, but we have mucus for some very good reasons.What purpose does the word slime serve in this sentence? A. It introduces the idea that the presence of mucus has health benefits for most humans. B. It introduces the idea that bodies are under attack whenever there is mucus. C. It refers to most humans' opinion of mucus and contrasts with the more scientific term. D. It suggests mucus deserves the lack of respect it receives. 2.
