Answer:
40 cm²
Step-by-step explanation:
Given the ratio of radii = a : b , then
ratio of areas = a² : b²
Here ratio of radii = 1 : 2
ratio of areas = 1² : 2² = 1 : 4
Thus
surface area of large sphere = 4 × 10 = 40 cm²

The rectangle below has an area of 15k4 +35k3+20k2
What is the width and length
Answers
Answer:
the answer is 5
Step-by-step explanation:
it is right jk
Answer:
Step-by-step explanation:
We know area of a rectangle is xy where x and y are its dimensions.
A=xy
If we factor the area we will get the dimensions.
A=15k^4+35k^3+20k^2
(this can be factored in many ways to produce the same area, the answer choices you are given can be any given combination of factors.)
A=15k^4+15k^3+20k^3+20k^2
A=15k^3(k+1)+20k^2(k+1)
A=(15k^3+20k^2)(k+1) (this is one way)
A=5k(3k^2+4k)(k+1)
A=(3k^2+4k)(5k^2+5k) (and another way)
Either expression would give you width and length (or length and width) as they all produce the area of the original equation.

0.05
2
0.025
3 0.0125
Answers
Answer:
The exponential equation is;
y = 0.1•0.5^x
Step-by-step explanation:
Here, we want to get the exponential function represented by the table
Mathematically, the general form of an exponential function is;
y = a•b^x
By getting a and b, we have the exponential function
We can use any of the points;
Let us start with (0,0.1)
0.1 = a•b^0
anything raised to zero is 1
0.1 = a * 1
a = 0.1
Now, we have a
Let us work with the second point to get b
The point is (1,0.05)
0.05 = 0.1•b^1
0.05 = 0.1b
b = 0.05/0.1
b = 0.5
Thus, we have the equation as;
y = 0.1•0.5^x

If she wants to at least match her previous average, then what is the minimum number of goals she must score in order to maintain her previous average?
Answers
Answer:
Number of goals to convert in game 5= 3 goals
Step-by-step explanation:
Giving the following information:
A soccer player's average during her first two seasons was 1.4 goals per game.
First, we need to determine the number of goals converted:
Goal games 1-4= 4
Now, the number of goals she must have at five games and by the difference the number of goals to convert:
Number of goals for five games= 1.4*5= 7
Number of goals to convert= 7 - 4= 3 goals

Rewrite this expression without using absolute value
I nEeD hElP qUiCk!
Answers
Answer:
Step-by-step explanation:
Normally when you are doing an absolute value question, you do it like this
y = abs(4x - 12) and you write the absolute value equation as
y = 4x - 12 and
y = - 4x + 12
These two are shown in graph27a
to show both wings of the absolute value curve
This is slightly different.
I think you would write this as
y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b

Sonu had ₹25.50. He bought one pen for ₹17.75. How much money does he
have now?
PLS WRITE STEP BY STEP EXPLAINTION
Answers
Answer:
He has $7.75 left.
Step-by-step explanation:
To solve this problem you must subtract $25.50 by $17.75 because he bought the pen for 17.75 which is being taken away from his amount of money to start with ($25.50).
Step by step solving the subtraction problem:
$25.50-$17.50 = $7.75
So 25.50 - 17.75 you would need to make the 0 become a ten and then subtract 10 and 5, then you bring down the 5 from ($25.50) and make it 14 and subract 14 and 7. Then bring down the other 5 and make it 14 as well and subract 14 by 7 which is 7. Finally make the 2 a 1 and it will end up being 1-1 which is zero. So the answer will end up being $7.75. Hope that helps. Sorry that this answer took long for it to be posted.
