A circle has a radius of 4 feet. What is the radius of a bigger circle if the scale factor of the smaller to bigger is 4:9
Answer:
9 feets
Step-by-step explanation:
From the question, we have our scale factor as:
4:9 = 4/9
Smaller circle /Bigger circle = 4/9
A circle has a radius of 4 feet. What is the radius of a bigger circle?
Let the radius of the bigger circle = x
This is calculated as:
4/9 = 4/x
Cross Multiply
4x = 9 × 4
x = 36/4
x = 9 feet
Therefore, the radius of the bigger circle is 9 feet

What factoring method do you use to factor u²+70
1) difference of
squares
2) GCF
3) not foctorable
4) factor trinomial
Answer: 3) Not factorable
We cannot use the difference of squares method because we don't have a subtraction going on (ie "difference") and we don't have two perfect squares. The value 70 is not a perfect square.
We cannot factor out a GCF since the GCF here is 1, and that doesn't really affect things. Choice 4 is also not applicable because we don't have a trinomial. A trinomial has three terms.
Lilly babysits for $10 per hour. She works for 5 hours. She uses her money to buy a new sweater that cost $20.
How much money will Lilly have left?
Answer:
30 dollars left
Step-by-step explanation:
If Lily works for 10 dollars per hour and works 5 hours which adds up to 50 dollars then she buys a sweater for 20 so 50 minus 20 is 30 dollars, so Lily has 30 dollars left over.

Three cups of sugar and six cups of flour are required to bake the cake, if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.
What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given data:
A recipe for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.
Calculate the ratio for 1 cake
1 cup of sugar / 2 cups of flour
Calculate the sugar and flour for 3 cake
1 cup of sugar / 2 cups of flour × 3
3 cups of sugar / 6 cups of flour
Therefore, 3 cups of sugar and 6 cups of flour are required to bake the cake if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.

(2 – 4)(2x + 3)
Answer:
-2(2x+3)
Step-by-step explanation:
Answer:
-2 (2x + 3)
Step-by-step explanation:
We need to use FOIL
Multiply the FIRST terms of each set together
Then the OUTSIDE terms
Then the INSIDE terms
and then the LAST terms
Thus:
[tex]2*2x = 4x[/tex]
[tex]2*3 = 6[/tex]
[tex]-4*3 = -12[/tex]
[tex]-4*2x = -8x[/tex]
So finally we end up with 4x + 6 - 12 - 8x
Simplifying this gives us -4x - 6
We can then factor out -2 from each factor, giving: -2(2x+3)
Hope this helps!

In the equation a and b represent the price per night for a room in hotel a and hotel b respectively w week s
Answer:
A = $80
Step-by-step explanation:
A = 240 - 20w
B = 320 - 30w
Equate both equations
240 - 20w = 320 - 30w
Collect like terms
240 - 320 = -30w + 20w
-80 = -10w
Divide both sides by -10
w = -80/-10
w = 8
Substitute w into equation A
A = 240 - 20w
= 240 - 20(8)
= 240 - 160
= 80
A = $80

Answer:
y = - 2x + 9
Step-by-step explanation:
From y = -2x + 1
comparing with y = mx + c
slope (m) = - 2
Writing in point slope form
y - y1 = m(x - x1)
y - 1 = -2( x - 4)
y - 1 = -2x + 8
Now writing in slope intercept form
y = - 2x + 8 + 1
y = -2x + 9

What’s 25 dived by 9 in long (step by step)
Answer:
Step 1:
Start by setting it up with the divisor 9 on the left side and the dividend 25 on the right side like this:
9 ⟌ 2 5
Step 2:
The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
9 ⟌ 2 5
Step 3:
Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.
0
9 ⟌ 2 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
9 ⟌ 2 5
- 0
2
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
9 ⟌ 2 5
- 0
2 5
Step 6:
The divisor (9) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:
0 2
9 ⟌ 2 5
- 0
2 5
Step 7:
Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:
0 2
9 ⟌ 2 5
- 0
2 5
1 8
Step 8:
Subtract the result in the previous step from the number written above it. (25 - 18 = 7) and write the answer at the bottom.
0 2
9 ⟌ 2 5
- 0
2 5
- 1 8

The phrase "This is just the tip of the iceberg" is often used. It refers to the huge masses of ice that float in the oceans and only show a small fraction of their structure on the surface. Most of the icebergs hide below the water level. Based on the diagram below, what is the likely density of icebergs? (The density of salt water in the oceans is 1.03 g / ml.)
PLS HELP I WILL GIVE BRAINLIEST ASAPP THIS IS URGENT
Answer: 0.90 g/cm3
Step-by-step explanation:
Their ratio is given by the mass density of ice: M/V = Rhoi ~ 0.90 g/cm3 (iceberg ice is more dense than normal ice since it has been compressed by thousands of years of pressure - normal ice is 0.917 g/cm3).
Answer:
Basal melting of floating ice shelves and iceberg calving constitute the two ... of the Southern Ocean free of large icebergs are largely populated by small iceberg the hidden part, which is the most important in terms of effort and often the most So this work explores use of NISAR to map surface structures visible on ice

Franklin uses the distributive property to write an expression equivalent to 18 + 36. Which of the following best represents Franklin's expression?
18(1+ 4)
18(2 +2)
6(2+6)
Answer: 9(2+4)
Step-by-step explanation:
18 + 36 = 54
18(1+4) = 90
18(2+2) = 72
9(2 + 4) = 54
6(2+6) = 48
The best representation of the expression 18 + 36 after using distributive property is 18(1 + 2).
What is distributive property?Distributive property explains to us how to solve expressions in the form of a(b + c).
After apply distributive property this term convert as ab+ac.
The given expression is,
