Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The Smiths are sending out a batch of holiday cards. Emily signed of the cards. Then Josh signed of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed? There are cards yet to be signed.
Answers
The answer is 32
Emily signed 2/5 so 75 divided by 5 is 15
15x2 is 30
75-30=45
45 divided by 1/9 is 5
30+5=35
so then 45-5=40
20% of 40 is 8
30+5+8 = 43
75-43=32
Answer:
You will get 75 cards

-5/6b = 30
Answers
Answer:
b = -36
Step-by-step explanation:
In other words, solve this given equation -5/6b = 30 for b.
For clarity we rewrite this as (-5/6)b = 30.
To isolate b, we multiply both sides of the above equation by (-6/5):
(-6/5)(-5/6)b = (30)(-6/5), or
b = -36

of the box of cereal. How many ounces are left in the box?
Answers
Answer:
2 ounces
Step-by-step explanation:
1 = 5/8 - 1/4 = 1/8
16 x 1/8 = 2 oz
Answer:
2 ounces left
Step-by-step explanation:
if anna ate 5/8 of the box, and Bill has eaten 1/4 of the box, then in total they’ve eaten 7/8 if the box (1/4 turns into 2/8 + 5/8)
1/8 of the box is left and 1/8 of 16 is 2. so 2 ounces would be left

Answer:
The answer is option 1.
Step-by-step explanation:
You have to apply Gradient formula :
b. inventing analytic geometry
c. developing a heliocentric theory
Question 2.2. Which was not an accomplishment of Galileo Galilei?
a. creating a powerful telescope
b. writing the Principia Mathematica
c. confirming that the earth revolves around the sun
Question 3.3. Which best describes the influence of Isaac Newton's theory of universal gravitation?
a. It led to new insights into the nature of light.
Answers
c. developing a heliocentric theory
2. Which was not an accomplishment of Galileo Galilei?
c. confirming that the earth revolves around the sun
3. Which best describes the influence of Isaac Newton's theory of universal gravity?
It showed that the universe follows a set of predictable rules
Final answer:
Nicolaus Copernicus developed the heliocentric theory. Galileo Galilei did not write the Principia Mathematica but he did confirm the earth revolves around the sun with his improved telescope. Isaac Newton's theory of universal gravitation significantly advanced our understanding of the physical universe.
Explanation:
Nicolaus Copernicus is renowned for developing the heliocentric theory, according to which the sun is the centre of the universe and the earth and other planets revolve around it. This answer corresponds to option C in your question. Galileo Galilei, on the other hand, did not write the Principia Mathematica. This work was written by Sir Isaac Newton, and thus corresponds to option B of your second question. Galileo is well-known for advancing the telescope technology, and his observations confirmed the heliocentric system.
As for your third question, Isaac Newton's theory of universal gravitation revolutionized our understanding of the physical universe. While it did lead to new insights into light, it's most significant contribution is perhaps its explanation of how objects in the universe are attracted to each other, demonstrating that the same forces are at work in the heavens and on earth.
