Answer:
$8190
Step-by-step explanation:
So we know that were putting away $2 each month from our allowance.
Jan-$2
Feb-$4
March-$8
April-$16
Ok so we already put away 4 months of our allowance from 12. So we need 8 more months to count how much.
So lets add: 2 + 4 + 8 + 16=30
Now we need to figure out how much in May and so on.
May- 16x2=32
June-32x2=64
July-64x2=128
August-128 x 2=256
September-256 x 2=512
October-512 x 2=1024
November-1024 x 2=2048
December-2048 x 2=4096
In total to add:
2 + 4 + 8 + 16 + 32 +64 + 128 + 256 + 512 + 1024 + 2048 + 4096 = 8190
Hope this helps :)

In a song competition, a participant has to score a total of at least 20 points in the first four rounds combined to move on to the fifth and final round. Curtis scored 2 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Curtis scored in each of the second, third, and fourth rounds if he earned a place in the finals?
2 + 3p ≤ 20
2p + 3 ≥ 20
2 + 3p ≥ 20
2p + 3 ≤ 20
Answer:
C
Step-by-step explanation:
Answer:2+3p ≥ 20
Step-by-step explanation:
2 is the amount of points he earned
3 is how many rounds were left before finals
p is the additional points he earned
and ≥ 20 is he had to earn greater than or equal to 20 points total to move on.

Someone PLS HELP BRAINLIEST....The length of a rectangle is 3m more than twice the width, and the area of the rectangle is 35m^2 . Find the dimensions of the rectangle.
Length:
Width:
Let width of the rectangle be x.
Therefore ,Length= 3 + 2x
Area= 35
(3+2x)* x =35
3x + 2x^2 - 35 = 0
(2x-7)(x+5)
Therefore x=3.5
Length is 10 and Width is 3.5
Answer:
Area = length × width
90 = (3+2w) × w
w(2w + 3) = 90
2w² +3w = 90
2(w² +3/2w) = 90
Divide both sides by 2
2(w² +3/2w)/2 = 90/2
w² + 3/2w = 45
w² + 3/2w + (3/2•2)² = 45 + (3/2•2)²
w² + 3/2w + (3/4)² = 45 + (3/4)²
w² + 3/2w + 9/16 = 45 + 9/16
(w + 3/4)² = 729/16
Take the square root of both sides
√(w + 3/4)² = √729/16
w + 3/4 = 27/4
w + 3/4 -3/4 = ±27/4 - 3/4
w = 27/4 - 3/4 w = -27/4 - 3/4
w = 6m w = -7.5m
Area = length × width
90 = l × 6m
when x = 6m when x = -7.5 m
l = 90 m²/6m l = 90 m²/-7.5m
l = 15 m l = -12m
We cannot have negative dimension so
A = 90m²
l = 15m
w = 6m

Kenny is ordering uniforms for both the girls’ and boys’ tennis clubs. He is ordering shirts for 43 players and two coaches at a total cost of $658.35. Additionally, he is ordering visors for each player at a total cost of $368.51. How much will each player pay for the shirt and visor?

Simple answer
Need b4 10:00
Thanks!
Answer:
$22.82. Explanation: There are 45 total shirts and visors needed, for the 43 players and 2 coaches. So divide each of the total costs by 45 , to see how much each individual person pays:
SHIRT:
658.38/45 =$14.63 per person
VISTOR:
368.51/45 =$8.19per person
Each person is buying a shirt and a visor, so combine these two prices:
14.63+8.19=$22.82per person.

Question 7
Please help me out.
Correct answer will be marked brainlest.
Answer:
60 cm²
Step-by-step explanation:
The shaded area is calculated as
area of trapezium - area of white triangle
The area (A) of trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h( b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 12, b₁ = 14 and b₂ = 10 , then
A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 10) = 6 × 24 = 144 cm²
The area (A ) of the white triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 14 and h = 12
A = [tex]\frac{1}{2}[/tex] × 14 × 12 = 7 × 12 = 84 cm²
shaded area = 144 - 84 = 60 cm²

Suppose the 4th term of an arithmetic sequence is 27, and the 8th term
is 59.
1. What are the first term and the common difference?
2. Write a function for the sequence.
Answer:
The first term is 3 and common difference is 8.
And
The formula for sequence is: [tex]a_n = -5+8n[/tex]
Function is: [tex]f(n) = f(n-1)+8[/tex]
Step-by-step explanation:
Given that
[tex]a_4 = 27\\a_8 = 59[/tex]
The general formula for arithmetic sequence is:
[tex]a_n = a+(n-1)d[/tex]
Here
a is the first term
n is the term number
and d is the common difference
for 4th term
[tex]a_4 = a+(4-1)d\\27 = a+3d\ \ \ Eqn\ 1[/tex]
For 8th term
[tex]59 = a+ (8-1)d\\59= a+7d\ \ \ \ \ Eqn\ 2[/tex]
subtracting equation 1 from equation 2
[tex]59-27 = a+7d-(a+3d)\\32 = a+7d-a-3d\\32 = 4d\\d =\frac{32}{4}\\d = 8[/tex]
Putting d = 8 in equation 1
[tex]a+3d = 27\\a+3(8) = 27\\a+24=27\\a = 27-24\\a = 3[/tex]
Now for the function
[tex]a_n = a+(n-1)d\\a_n = 3+(n-1)(8)\\a_n = 3 + 8n-8\\a_n = -5+8n[/tex]
The sequence can also be expressed as a function as:
[tex]f(n) = f(n-1) + 8[/tex]
Hence,
The first term is 3 and common difference is 8.
And
The formula for sequence is: [tex]a_n = -5+8n[/tex]
Function is: [tex]f(n) = f(n-1)+8[/tex]

find the equation of the straigt line
if you are correct then ill give you brainliest answer!
Given :
A graph with a straight line on it.
To Find :
The equation of the line.
Solution :
From the given graph we can see that the line passes through point ( 0,6 ) and ( 4,10 ) .
Also, equation of line passes through two points [tex](x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex] is :
[tex]y - y_1 = (\dfrac{y_2-y_1}{x_2-x_1})( x - x_1)[/tex]
Putting all given values, we get :
[tex]y - 6 = (\dfrac{10-6}{4-0})( x -0)\\\\y - 6 = x\\\\y -x = 6[/tex]
Therefore, the equation of line is y - x = 6 .

Answer:
x=5
Step-by-step explanation:
The sum of the measures of angle M and angle R is 90°
Given;
•Angle M is (5x+10)°
•Angle R is 55°
The value of x therefore is;
Measure of Angle M + Measure of Angle R = 90°
(5x+10°)+55°=90°(Remove bracket)
5x+10°+55°=90°
5x+65°=90°
5x=90°-65°
5x=25(Divide both sides by 5)
x=5
Therefore the value of x=5
