Answers
Answer:
The question is corrected to get;
405,852
Step-by-step explanation:
The expression of the description when written as follows;
'I am a 6-digit number one of my 4s is worth 400,000. The other 5 is worth 1/100 as much. My 5 is worth 5 (10s). y 8 is worth 800. My 2 is' worth 2. My other digit is a 0 what number am I, we have;
The number of digits in the number = 6
The position of the number 4 = 100,000s, we have;
4xx,xxx
The position of the number 5 is in the 10s position, we have;
4xx,x5x
The other 5 = 50100 = 0.5
Therefore, we have;
4xx,x5x.5
The position of the 8 is the 100s, to give;
4xx,85x.5
The number 2 is in the unit position, therefore, we have;
405,852

Leo is 13 3 4 years old. Sheila is 1 1 2 years older than Leo and Jane is 1 1 5 years older than Sheila. How old is Jane?
Answers
Answer:
16 9/20 years old
Step-by-step explanation:
Leo is 13 3/ 4 years old.
Step 1
Sheila is 1 1 /2 years older than Leo
Sheila = 13 3/4 years + 1 1/2 years
13 + 1 + ( 3/4 + 1/2)
Lowest common denominator 4
14 + ( 3 + 2/4)
14 + 5/4
= 14 + 1 1/4
= 15 1/4 years old
Jane is 1 1/ 5 years older than Sheila.
Jane's age = 15 1/4 years old + 1 1/5 years
15 + 1 + (1/4 + 1/5)
Lowest common denominator = 20
16 + (5 + 4/20)
16 9/20 years old
Therefore, Jane is 16 9/20 years old
A soup bowl is in the shape of a hemisphere with a diameter of 10 cm. What is the approximate maximum volume of soup that the bowl can hold? A 2.094 cm B. 524 cm C. 262 cm
Answers
Answer:
C. 262 cm
Step-by-step explanation:
Use the formula for the volume of a sphere, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
Since the diameter is 10 cm, the radius will be 5 cm
Plug in the radius into the formula:
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](5³)
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](125)
V = 523.6
Since the bowl is a hemisphere, divide this by 2:
523.6/2
= 261.8
Rounding to the nearest cm, the volume of the bowl is 262 cubic cm.
So, the correct answer is C. 262 cm

1⁵ + 5² / 25⁰ - 5¹=
Answers
Answer: 6.5
Step-by-step explanation:
1 (to the power of 5) is 1 and 5 (to the power of 2) is 25.
25 (to the power of 0) is 1 and 5 (to the power of 1) is 5.
1 + 25 = 26 and 1 - 5 = -4.
Since the slash means division in math and any number to the power of 0 is always 1.
The answer would be: -6.5.
The solution for the expression [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex] after simplifying is,
[tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)} = \frac{- 13}{2}[/tex]
We have to give that,
The expression to simplify is,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Simplify the expression by simplifying each term in a given fraction,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Since,
1⁵ = 1
5² = 5 × 5
= 25
25⁰ = 25
5¹ = 5
Substitute all the values,
⇒ [tex]\frac{(1 + 25)}{(1 - 5)}[/tex]
⇒ [tex]\frac{26}{-4}[/tex]
⇒ [tex]\frac{-26}{4}[/tex]
Simplify the fraction in simplest form,
⇒ [tex]\frac{- 13}{2}[/tex]
Hence, The solution is, - 13/2
