Which statement best describes the garph of 2x-5y=-25 and the graph of 5/2x+5
Step-by-step explanation:
52+5\frac{5}{2}x+5
25x+552+5
52+5\frac{5x}{2}+525x+552+2⋅52
52+2⋅52\frac{5x}{2}+\frac{2 \cdot 5}{2}25x+22⋅55+2⋅52
5+2⋅52\frac{5x+{\color{#c92786}{2}} \cdot {\color{#c92786}{5}}}{2}25x+2⋅55+102/
Solution:
5+102\frac{5x+10}{2}25x+10

Answer:
c
Step-by-step explanation:
A penny is about 0.0625 of an inch thick.
a. In 2011 there were approximately 5 billion pennies minted. If all these pennies were placed in a single stack, how many miles high would that stack be?
b. In the past 100 years, nearly 500 billion pennies have been minted. If all these pennies were placed in a single stack, how many miles high would that stack be?
c. The distance from the moon to the earth is about 239,000 miles. How many pennies would need to be stack in order to reach the moon?
a) The height of the stack would be is 4932.13 miles
b) The height of stack is 493213 miles
c) 2,42,28,86,40,000 need to be stack in order to reach the moon
What is Unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
thickness of penny = 0.0625
a) if 5 billion pennies minted
Then, height of the stack would be
= 5,000,000,000 x 0.0625
=31,25,00,000 miles
= 31,25,00,000 / 12 x 5280
=4932.13 miles
b) In the past 100 years, nearly 500 billion pennies have been minted.
Now, the height of stack
= 4932.13 x 100
=493213 miles
c) let x be the number of pennies in a stack which reaches the moon then we have the equation
x × 0.0625 =239,000miles.
x =(239,000 / 0.0625 miles) ×5280 ×12
x = 38,24,000 x 5280 x 12
x = 2,42,28,86,40,000

Use picture to answer questions
Answer:
The answer is A. The length is 3 times the width.
Step-by-step explanation:
In the picture, it tells us that m is the width. That must mean that 3m is the length. m × 3 = 3m, so when you substitute it, it becomes width × 3 = length.

Referring to the figure, find the volume of the solid
shown. Use 3.14 for π. Round to the nearest whole number.
Answer:
34483.48 in³
Step-by-step explanation:
We know ,
Volume = πr²hSubstitute ,
V = 3.14 * 17 * 17 * 38 in.³V = 34483.48 in.³Answer:
34,483.48!
Step-by-step explanation:
The formula for calculating the volume of a cylinder is π · r^2 · h. We can replace the numbers, like this: 3.14 · (17)17· 38. 17 times 17 is 289, so 3.14 · 289 · 38. 289 times 38 is 10,982, so 3.14 · 10,982. 3.14 times 10,982 is 34,483.48, so the volume of the cylinder is 34,483.48.
Hope this helped!

Circle A has a diameter of 9 cm. Circle B has a radius of 5 cm.
Calculate the circumference of each. What's the difference in length of the circumference of these two circles?
About 3.14 centimeters
About 12.56 centimeters
About 25.12 centimeters
About 1.02 centimeters
Answer:
c
Step-by-step explanation:
Answer:
The difference in circumference is about 25.12 centimeters
Step-by-step explanation:
You find diameter by multiplying the radius by 2. So with that being said, the diameter of circle A is 18cm and the diameter of circle B is 10cm.
You calculate circumference by multiplying ur diameter by pi (3.14)
18 cm x 3.14 = 56.52 cm so the circumference of Circle A is 56.52 cm.
10cm x 3.14 = 31.9 cm so the circumference of circle B us 31.9 cm.
56.56
-31.9
= 24.62
24.62 is the around 25.12 cm

How to Round:
If the number following the number you're going to round up is 5 or above, (5, 6, 7, 8, or 9), then round up. (E.X. 29 rounded up is 30. Since 9 is above 5, you will round up.
On the other hand, if the number following the number you're going to round is 4 or below, (4, 3, 2, or 1), you don't round up, instead you keep it the same, and if they're are decimals, you turn the following numbers to 0s. (E.X. 32.4536 rounded to the nearest hundredth (32.4536) is 32.45. Since 3 is less than 4, you're not going to round up. The number in the hundredth's place stays the same (5), and the following rest turn to 0s. Leaving you with 32.45
