Today, Reza ate 20 grapes, which was 400% as many
grapes as he ate yesterday. Explain how to use
equivalent ratios to find the number of grapes Reza ate
yesterday. (help plz)

Answers

Answer 1

its not a sin to want to win cant see meflying like a bee i see a dreamer other there by the water but i

LOL

Answer 2

Answer:

What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.

To do it, let:

x: number of grapes that Reza ate yesterday

(x / 20) = (100/400).

Clearing x we have:

x = (100/400) * (20) = 5

answer

the number of grapes Reza ate yesterday was 5

since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.

B = C / root2

x = root3 / root2

What is 3/4 x 6 , simplified .

Answers

Answer:

9/2

Step-by-step explanation:

3/4 x 6 can be thought of as multiplying 3/4 x 6/1

When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.

3/4 x 6/1 = (3x6)/(4x1)

3/4 x 6/1 = (18)/(4)

3/4 x 6/1 = 9/2

Okay so for a pack of 12 confetti eggs, you pay $2.88. to find the unit price, or price for 1 egg, you just take 2.88 divided by 12 (which i already did) and you get 0.24. so the price for 1 confetti egg is $0.24 or 24 cents.

James reads 520 words in 2 minutes. Luke reads 960 words in 5 minutes. All we need to find out is how many words can they read in 1 minute? All ewe do is take 520 divided by 2, and you get 260. Then you take 960 divided by 5, and you get 192. so the rates they read at is 260 wpm and 192 wpm.

A shipping and handling fee is 35.00 right? so what you want to find is “35.00 is what percent of 437.50?” and if you think about it and go through it, 35 is 8% of 437.50. so 8% of the total is the shipping and handling fee!

Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf. What inequality matches this scenario

Answers

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf.

The inequality that matches this scenario will be:

x ≥ 12.

Since there were at least 12 games, we would use the greater than or equal to sign.

length of edges in A: length of edges in B = 3:5
The perimeter of A is 345 mm
Work out the perimeter of B in mm.

Answers

Answer:

575 mm

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of sides.

let x be the perimeter of B then by proportion

[tex]\frac{3}{345}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )

3x = 1725 ( divide both sides by 3 )

x = 575

Then the perimeter of B is 575 mm

A ceramic vase that cost an antique store $7 was marked $63. What is the percentage markup on the price of the ceramic vase?
A-56%
B-900%
C-800%
D-44%

Answers

9514 1404 393

Answer:

  C)  800%

Step-by-step explanation:

The markup amount is the difference between the selling price and the cost:

  markup = selling price - cost

  markup = $63 -7 = $56

The percentage markup relative to the cost is ...

  markup/cost × 100%

  = ($56)/($7) × 100%

  = 8×100% = 800%

Excerpt from Stuff Matters By Mark Miodownik In the absence of copper, gold, and meteoric iron, our ancestors tools during the Stone Age were made of flint, wood, and bone. Anyone who has ever tried to make anything with these kinds of tools knows how limiting they are: if you hit a piece of wood it either splinters, cracks, or snaps. The same is true of rock or bone. Metals are fundamentally different from these other materials because they can be hammered into shape: they flow, they are malleable. Not only that, they get stronger when you hit them; you can harden a blade just by hammering it. And you can reverse the process simply by putting metal in a fire and heating it up, which will cause it to get softer. The first people to discover these properties ten thousand years ago had found a material that was almost as hard as a rock but behaved like a plastic and was almost infinitely reusable. In other words, they had discovered the perfect material for tools, and in particular cutting tools like axes, chisels, and razors. This ability of metals to transform from a soft to a hard material must have seemed like magic to our ancient ancestors. *** In 1961 Professor Richmond from Oxford University discovered a pit that had been dug by the Romans in AD 89. It contained 763,840 small two-inch nails, 85,128 medium nails, 25,088 large nails, and 1,344 extra-large sixteen-inch nails. The hoard was of iron and steel and not gold, which most people would have found bitterly disappointing. But not Professor Richmond. Why, he asked himself, would a Roman legion bury seven tons of iron and steel? The legion had been occupying the advance headquarters of Agricola in a place called Inchtuthil in Scotland. This was at the outer reaches of the Roman Empire, and their mission was to protect its border from what they saw as the savage tribes who threatened it: the Celts. The legion of five thousand men occupied the region for six years before retreating and, in the process, abandoning their fort. They made great efforts to leave behind nothing that could help their enemies. They smashed all food and drink containers and burned the fort to the ground. But they werent satisfied with this. In the ashes were the steel nails that had held the fort together, and they were far too valuable to be left to the tribes that had driven them out. Iron and steel were the materials that enabled the Romans to build aqueducts, ships, and swords; they allowed them to engineer an empire. Leaving the nails to their enemies would have been as useful as leaving a cache of weapons, so they buried them in a pit before marching south. The author draws a contrast between metals and other materials in all of the following EXCEPT: A) Flint, wood, and bone are more brittle. B) Metals are reusable. C) Metals are non-polluting. D) Metals can be shaped into other objects. Describe key sections that areas included in writing a report. Read the sentence. Then explain why it is punctuated correctly or incorrectly.1.
