Answer:
-6665
Step-by-step explanation:
The given GP is :
1, -6, 36, ...
Number of terms = 6
The sum of n terms of a GP is given by :
[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]
Here,
a = 1, n = 6, r = 36/-6 = -6
So,
[tex]S_6=\dfrac{1((-6)^6-1)}{(-6)-1}\\\\=-6665[/tex]
So, the sum of th GP is -6665.

The length of Bryan’s garden is 4 meters longer than 3 times the width. The perimeter of his garden is 72 meters. What are the dimensions (l, w) of his garden?
Answer:
8 m = width
28 m = length
Step-by-step explanation:
Let w = width
3w + 4 = length
P = 2w + 2l
= 2w + 2(3w + 4) = 72
2w + 6w + 8 = 72
8w + 8 = 72
8w = 64
w = 8 m = width
3w + 4 = 24 + 4 = 28 m = length

The first side of a triangle is 4 inches longer then twice th second side the third side of a trianhle
Question:
The first side of a triangle is four inches longer than twice the
second side. The third side of the triangle is 5 inches shorter than
the sum of the other two sides. The perimeter is 72 inches. Find
the lengths of the three sides.
Answer:
The sides of the triangle are: 11.5, 27 and 33.5
Step-by-step explanation:
Let the first side be f, the second be s and the third be t.
So, we have:
[tex]f =4 + 2s[/tex]
[tex]t = f + s - 5[/tex]
[tex]Perimeter = 72[/tex]
Required
Determine the length of the three sides
Perimeter is calculated as:
[tex]Perimeter = f + t + s[/tex]
Substitute values for f and t
[tex]Perimeter = 4+2s + f+s-5 + s[/tex]
[tex]Perimeter = f+2s +s+s-5+4[/tex]
[tex]Perimeter = f+4s-1[/tex]
Substitute values for f and Perimeter
[tex]72 = 4+2s+4s-1[/tex]
[tex]72 = 2s+4s-1+4[/tex]
[tex]72 = 6s+3[/tex]
Collect Like Terms
[tex]6s = 72 -3[/tex]
[tex]6s = 69[/tex]
[tex]s= 11.5[/tex]
[tex]f =4 + 2s[/tex]
[tex]f = 4 + 2 *11.5[/tex]
[tex]f = 27[/tex]
[tex]t = f + s - 5[/tex]
[tex]t=27+11.5 - 5[/tex]
[tex]t=33.5[/tex]
The sides of the triangle are: 11.5, 27 and 33.5

There are 24 boys and 16 girls in a hall, each holding coins in their hand.The mean number of coins for the children is 11, The mean number of coins for the boys is 9 Work out the mean number of coins for the girls.
Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14

Answer:
The answer is 6.5 hours.
Step-by-step explanation:

A road is inclined at an angle of 6°. After driving 5,440 feet
along this road, find the driver's increase in altitude. Round to
the nearest foot.
The driver's increase in
altitude is ____ ft.
A. 5,410
B. 569
C. 52,043
D. 572
========================================================
Work Shown:
sin(angle) = opposite/hypotenuse
sin(6) = a/5440
5440*sin(6) = a
a = 5440*sin(6)
a = 568.634840176034
a = 569 feet, which shows why choice B is the answer.
This value is approximate. Make sure your calculator is in degree mode. One way to check is to compute sin(30) and you should get 0.5
side note: 569 feet is roughly equal to 0.1078 miles.
The driver's increase in altitude is 569 feet.
Given that,
A road is inclined at an angle of 6°.
After driving 5,440 feet along this road,
We have to determine,
The driver's increase in altitude?
According to the question,
A road is inclined at an angle of 6°.
After driving 5,440 feet along this road,
The inclination is determined by using the sin angle.
Therefore,
The driver's increase in altitude is,
[tex]\rm Sin \theta = \dfrac{Perpendicular}{Hypotenuse}\\\\[/tex]
Where Perpendicular = a, angle = 6 degree and hypotenuse = 5,440ft.
Substitute all the values in the formula,
[tex]\rm Sin \theta = \dfrac{Perpendicular}{Hypotenuse}\\\\\rm Sin6 = \dfrac{a}{5440}\\\\\rm 0.104= \dfrac{Perpendicular}{5440}\\\\Perpendicular = 5440 \times 0.104\\\\Perpendicular = 569 \ feet[/tex]
Hence, The driver's increase in altitude is 569 feet.

Alex bought a present for his friend. The box, with its dimensions, is shown below.
If Alex has 60 square inches of wrapping paper, does he have enough paper to wrap the gift? (Assume that the shape of the wrapping paper doesn't matter.)
O yes because the gift has a surface area of 48 square inches
O no because the gift has a surface area of 96 square inches
O yes because the gift has a surface area of 32 square inches
O no because the gift has a surface area of 64 square inches
Answer:
yes because the gift has a surface area of 48 square inches
Step-by-step explanation:
Surface area formula:
