Answer:
These numbers are 3 and 9Step-by-step explanation:
x - smaller number
3x - three times the smaller number = the larger number
2×3x - twice the targer number
2×3x+3x - twice the larger is added to three times the smaller
2×3x + 3x = 27
6x + 3x = 27
9x = 27
÷9 ÷9
x = 3
3x = 3×3 = 9
What are the first four terms of the sequence shown below?
an = n3 + n2
Answer:
2, 12, 36, 80
Step-by-step explanation:
Substitute n = 1, 2, 3, 4 into the n th term formula, that is
a₁ = 1³ + 1² = 1 + 1 = 2
a₂ = 2³ + 2² = 8 + 4 = 12
a₃ = 3³ + 3² = 27 + 9 = 36
a₄ = 4³ + 4² = 64 + 16 = 80
this is for my lil sis. "Round 13.989 to the nearest tenth" to lazy to answer it for her
Answer:
14.0
Step-by-step explanation:
when rounded to the nearest tenth, 13.989 is 14.0.
Answer:
Hey!
Your answer for your lil' sis is 14!
Step-by-step explanation:
The tenth column is the column directly after the decimal point...
GREATER THAN 5 = Round up...
LESS THAN 5 = Round down...
So in this case it is 9 SO WE ROUND UP
This makes it 14.0
I HOPE THIS HELPEDYou play a game where you score -6 points on the first turn and on each of the next 3 turns. Your score after those 4 turns is
Answer:
-24
Step-by-step explanation:
You start with -6 points, and get another -6 on the rest of the turns which is a total of 4 turns.
-6 x 4 is -24
Unless this question is missing some information, this should be correct I believe.
Hope this helps!
The score after 4 turns is -24.
Given that, you play a game where you score -6 points on the first turn and on each of the next 3 turns.
We need to find what is the score after 4 turns.
What are integers?An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.
Now, the score after 4 turns = Score of the first turn + The next 3 turns
= -6 + 3(-6)
=-6-18
=-24
Therefore, the score after 4 turns is -24.

find the common ratio and the 12th term of the geometric sequence 64, 16, 4, ...
Answer:
common ration = 1/4
12th term = 1/65536
Step-by-step explanation:
64
64*1/4 = 16
16 * 1/4 = 4
4* 1/4 = 1
1 * 1/4 = 1/4
1/4*1/4 = 1/16
1/16*1/4 = 1/64
etc
1/256
1/1024
1/4096
1/16384
12th term = 1/65536
Answer:
see explanation
Step-by-step explanation:
The common ratio r is calculated as
[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{16}{64}[/tex] = [tex]\frac{1}{4}[/tex]
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 64 and r = [tex]\frac{1}{4}[/tex] , thus
[tex]a_{12}[/tex] = 64 × [tex](\frac{1}{4}) ^{11}[/tex] = 64 × [tex]\frac{1}{4194304}[/tex] = [tex]\frac{64}{4194304}[/tex] = [tex]\frac{1}{65536}[/tex]
Express two and forty five hundredths as a decima
Answer:
2.45
Step-by-step explanation:
"Two and forty five hundredths"
"Two" will be the number '2'.
"and" will indicate the decimal.
"forty five hundredths" is '.45'.
Two and forty five hundredths as a decimal would be '2.45'.
Hope this helps.
Answer:
2.45
Step-by-step explanation:
2/1 + 45/100 = 2 + 0.45 = 2.45
or
2.00
+ 0.45
-----------
2.45
or
200/100+45/100=245/100=2.45

Explain how to solve 2(x+3) = 10. What properties did you need to solve the equation?
Answer:
x = 2, Inverse property of subtraction
Step-by-step explanation:
Simplifying
2(x + 3) = 10
Reorder the terms:
2(3 + x) = 10
(3 * 2 + x * 2) = 10
(6 + 2x) = 10
Solving
6 + 2x = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 10 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 10 + -6
2x = 10 + -6
Combine like terms: 10 + -6 = 4
2x = 4
Divide each side by '2'.
x = 2
Simplifying
x = 2
Answer:
x = 2
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 2x + 6 = 10Subtract 6 to each side, so it now looks like this: 2x = 4Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 2I hope this helps!

1 Graph a line that contains the point (4,3) and has a slope of 1/2
(numbers on graph go up to 7)
Answer:
the points: (8,5) (6,4) (4,3) (2,2) (0,1) (-2,0) (-4,-1) (-6,-2) (-8,-3)
Step-by-step explanation:
the point (4,3) should be dotted first, start from the (0,0) go right 4 spaces then up 3 spaces. the slope 1/2 means up 1 space then right two spaces to start plotting points on the graph. and to continue the bottom of the line it would be -1/-2 which is down 1 space then left 2 spaces.
A $65 coat is on sale for 15% off,
what is the cost of the coat
after the sale?
Answer:
$55.25
Step-by-step explanation:
15% of $65: [tex]\frac{65}{1}[/tex] × [tex]\frac{15}{100} = \frac{975}{100}[/tex] $975/100 = $9.75$65 - $9.75 = $55.25I hope this helps!
$55.25 is the cost of the coat after the sale.
Step-by-step explanation:
Given:
Price of the coat = $65
Percentage of discount = 15%
To find:
The cost price of coat after the sale
Solution:
Cost price of coat = $65
Percentage of discount = 15%
The amount of discount will be 15% of the price of the coat.
Amount of discount :
[tex]=\frac{15}{100}\times \$65 \\=\$9.75[/tex]
The cost price of the coat:
[tex]=\$65-\$9.75=\$ 55.25[/tex]
$55.25 is the cost of the coat after the sale.

Answer:
42
Step-by-step explanation:
3 is equal to 42 degrees because when you have two parallel lines that have another line pass through both parallel lines the values of degrees are the same as the opposite side so:
42 = 3
2 = 4
and another way you could find the value of 3 is since there is a perpendicular line going through line p we know that since it is perpendicular that the angle between them is 90 so angle 3 is:
90 - (angle 4) = angle 3
You may use this method if you first solved for angle 4 or angle 2 and we can get angle 2 from:
180 - 42 = 138
we can do this because 42 + angle two should be 180 degrees since they are along line n.

The value of investments in the stock market change daily. Suppose you buy a stock for $3,789. It increases in value by 6% and then decreases 7% and then increases again by 7%. What is the new value? (round your answer to the nearest cent)
Answer:
The final value of the stock is $3,996.66
Step-by-step explanation:
Percentage Change
The x% of a number N is calculated as x*N/100. If there is an increase, that number is added to the original value, then the new value is:
N'=N+x*N/100
Operating:
N'=N(1+x/100)
That formula makes it easier to find the new values of increasing quantities. When the percentage is for decreasing, then the formula becomes:
N'=N(1-x/100)
The original value of the stock is N1=3,789. The first change is an increase of 6%, then the new value is:
N2=3,789(1+6/100)=3,789*1.06=$4,016.34
The stock value now decreases by 7%:
N3=4,016.34(1-7/100)=4,016.34*0.93=$3,735.20
Finally, the value increases again by 7%:
N4=3,735.20(1+7/100)=3,735.20*1.07=$3,996.66
The final value of the stock is $3,996.66
The length of a rectangular window is 4 more feet than its width w. The perimeter of the window is 64 feet. Write an equation that could be used to find the demensions of the window and determine the length and width of the window.
Answer:
The length of the window is 18 ft and its height is 14 ft
Step-by-step explanation:
System of Equations
Let's call:
L: Length of the window in feet
W: Width of the window in feet
According to the first condition of the problem:
[tex]L = W + 4\qquad\qquad [1][/tex]
The perimeter of the rectangle is 64 feet. The perimeter is calculated as:
P = 2L + 2W =64
Dividing by 2:
[tex]L + W = 32\qquad\qquad [2][/tex]
The system of equations [1] and [2] can be used to find the dimension of the window.
Substituting from [1]
W + 4 + W = 32
Simplifying:
2W = 32 - 4 =28
Solving:
W = 28/2 = 14
Using [1]:
L = 14 + 4 = 18
The length of the window is 18 ft and its height is 14 ft
