A trapezoid has four sides. The bottom base is three times the length of one of the diagonal sides. The top base is seven units less than the length of one of the diagonal sides. The diagonal sides are the same length. Write and simplify an expression to represent the perimeter of the trapezoid.

Answers

Answer: In Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.

I couldn’t answer the first one sorry

Answer ($3.30 or three dollars and thirty cents)

I’ve never been taught this before but I hope I helped and got it right! (Sorry if I got it wrong) So what it says is the artist has 2 liters of paint for a project. So in 1 liter, there’s 1000 milliliters. So in 2 liters there’s 2000 milliliters in all. It says he ended off with 350 milliliters left, and each milliliter costs 2 cents. So what I did was, I subtracted 350 by 2000 (which is the milliliters) and got 1650. Next what I did was multiplied 0.2 to 1650, (the 0.2 is the cents) and got 330. Next what I did was 1650 divided 330 and got 5. Next what I did to try and check if I was correct was 5 times 330 and I got 1650. (I’ve never done this but I tried my best so sorry if I got it wrong but if I got it right you are welcome).

(Also the answer is 3.30 or three dollars and thirty cents)

if a meal costs $66 what would be the total after tax?
(5.61 is tax)

Answers

Answer:

$5.61; 8.5 %

Step-by-step explanation:

Tax = $1.87 per $22 meal

For a $66 meal,

Tax = 66 × 1.87/22

Tax = 3 × 1.87

Tax = $5.61

=====

Tax rate = 1.87/22 × 100

Tax rate = 0.085 × 100

Tax rate = 8.5 %

A ratio is a comparison of two numbers or measurements. The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces.

How did the Invention of the cotton gin affect slave labor in the United States? My life is really depending on you guys!! Many years ago, parrots could talk just as humans do. Parrots always told the truth, so people greatly admired them. There was one old parrot who lived with a dishonest man, in a little house on the edge of town. This parrot was known in the town to be wise, honest, and good. One night, the man went out and stole his neighbors ox, and, the next day, the neighbor came to the thiefs house with several other people. She banged on the wooden front door until the thief answered. Did you steal my ox? asked the angry neighbor. Of course not, said the thief. Lets ask the bird, said another woman. He is always honest. They asked the bird, and he said Yes, he did steal the ox. What proof is the word of a bird? asked the thief. This bird cant be trusted because he doesnt always tell the truth. The people were unsure of what to do next, so they went away to think about it, promising to come back the next day. The thief knew he had to find some way to get his neighbors to not trust the parrot. They had to believe that the bird didnt always tell the truth. The clever thief came up with a plan. That night, while the parrot was sleeping next to the window, he placed a large dome over the birds cage. Then, he poured water over the top of the dome. The bird awoke to see water falling. He thought it must have been raining outside. He tried to go back to sleep but was awoken again by loud noises. The man was banging on the floor with a stick, out of the birds sight. The next morning, the neighbors came back. The thief said, I can prove that this bird is a liar. Ask him what the weather was last night. The bird told them, Last night there was a great thunderstorm. The people couldnt believe it! There was no storm last night. It was a clear night. The bird was a liar! They were so angry that they told the bird to go into the forest. The parrot was sad. After all, hed done nothing to deserve this. A mockingbird asked why the parrot was sad, and the parrot told his story. Why didnt you just repeat the words you heard, like I do? asked the mockingbird. People always like to hear their own words. What the man said wasnt true, the parrot replied. People dont always want to hear the truth, answered the mockingbird. Say what they say, and theyll think youre a wonderful bird. From then on, the parrot only repeated the words of people.Select the THREE correct answers.How does the man tricking the bird move the story forward? 1. It leads to the man telling the people that the bird lies sometimes.2. It leads to the people thinking that the parrot is a liar. 3. It leads to the parrot deciding to repeat only what people say. 4. It leads to the parrot being sent to live in the woods.5. It leads to the parrot telling the people that the man stole the ox.
