On number 12 I need hell
Answer:
1,600 dollars
Step-by-step explanation:
The easiest way to solve it is to find the dollar for 1 percent.
Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

B) [tex]4\sqrt{11}[/tex]
Step-by-step explanation:
A) You can add these expression because they contain the same square root:
[tex]6\sqrt{2} - 5\sqrt{2} = (6 - 5)\sqrt{2} =\sqrt{2}[/tex]
B) Same as above:
[tex]\sqrt{11} + 3\sqrt{11} = (1 + 3)\sqrt{11} = 4\sqrt{11}[/tex]
Answer:
[tex]A) \: 6 \sqrt{2} - 5 \sqrt{2} = (6 - 5) \sqrt{2} = \sqrt{2} \\ [/tex]
√2 is the right answer.[tex]B) \sqrt{11} + 3 \sqrt{11} = (1 + 3) \sqrt{11} = 4 \sqrt{11} [/tex]

Answer:
400
Step-by-step explanation:
Tge 6 in the tens place is greater than 5, so you round the 3 up to 4.
If the number that determines where you round is 5 or more, round up.
So 366 rounded to the hundreds place is 400.

Paula says that 2/3 is equivalent to 4/9 because 4 is a multiple of 2 and 9 is a multiple of 3. explain her error.
Answer:
Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.
Step-by-step explanation:
Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.
4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.
Thus, the correction is as follows:
Given the fraction
[tex]\frac{2}{3}[/tex]
Multiply the nominator and denominator of the fraction by 2
[tex]\frac{2\times 2}{3\times 2}=\frac{4}{6}[/tex]
Thus, the 4/6 is the correct equivalent expression of 2/3.

A group of nine friends go to a baseball game. The group buys 6 hotdogs and 3 hamburgers for a total of $27.75. A hamburger costs $1.75 more than a hot dog. What is the cost of a hamburger?
Answer:
let x be cost of a hotdog
let y be cost of hamburger
so,
5x + 4y = 17.75 eq. 1
4x + 5y = 18.25 eq. 2
manipulate eq. 1 so solve for x:
5x = 17.75 - 4y
x = 17.75/5 - (4/5)y
x = 3.55 - (4/5)y eq. 3
substitute eq. 3 to eq. 2:
4(3.55 - (4/5)y) + 5y = 18.25
14.2 - (16/5)y + 5y = 18.25
14.2 + (9/5)y = 18.25
(9/5)y = 18.25 - 14.2
4.05= (9/5)y
y = 2.25
x = 3.55 - (4/5)(2.25)
x = 1.75
hotdog costs $1.75
hamburger costs $2.25

I put a ladder 1.5m away from a tree. the ladder is inclined at 70 degrees about the horizontal. What is the height of the tree?
Answer:
4.121216129m
Step-by-step explanation:
use sohcahtoa
tan(70) x 1.5m = 4.121216129m
The height of the tree is 4.12 m.
Given,
I put a ladder 1.5m away from a tree.
The ladder is inclined at 70 degrees about the horizontal.
We need to find out what is the height of the tree.

Find the AB.
AB = height of the tree.
TanФ = AB / CB
Tan 70° = AB / 1.5m
2.7474 = AB / 1.5m
AB = 2.7474 x 1.5m
AB = 4.12 m
Thus the height of the tree is 4.12 m.

The percentage decrease in basketball participation from 2013-2014 to 2014-2015 is 0.35%.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information in the question,
Number of basketball participants in 2013-2014 = 974,398
Number of basketball participants in 2014-2015 = 970,983
Then, the percentage decrease in the participants,
% decrease = (974,398 - 970,983)/ 974,398 × 100
% decrease = 0.35%.

#11. y=7m+6
First subtract 6 over to the other side
y-6=7m
then divide the 7 over
(y-6)/7=m
m=(y-6)/7
#13 A=(Z+7)3
Divide the three over to the other side of the equation
A/3=Z+7
Now the 7 is free to be subtracted from both sides
(A/3)-7=Z
#17. (2x/5)-9=6
First add 9 to both sides
2x/5=6+9
2x/5=15
Multiply both sides of the equation by 5
2x=5(15)
2x=75
Divide by 2

Answer:
You need help with both or can I just help with one ?
Step-by-step explanation:
Answer:
14,275
1013
Step-by-step explanation:
1: To get the population in the year 2001 we would have to multiply 4500 by 1.08. To get the population in 2002 we would have to multiply: 4500(1.08)(1.08) or 4500(1.08)^2
Therefore you can write the following equation
4500(1.08)ⁿ where n is the number of years
we need is in 2015 and so n=15 so we have
4500(1.08)¹⁵=14274.5 which you should probably round to 14275
The second one is very similar to the first
to get from 1990 to 1991 you would multiply 5000*.93
so our equation would be
5000(.93)ⁿ where n is the number of years
1990-2012 is 22 so we have
5000(.93)²²=1012.96 which rounds to 1013
