Answer:
length= 90feet
width =72 feet
Step-by-step explanation:
perimeter=2(L+W)
324=2(L+W)
324/2=L+W
162=L+W( at a ratio of 10:8)
length=10/18 * 162=90
width=8/18*162=72
2(90+72)=324
Brian is going camping and. is making a tent from fabric. How much fabric will he need? 6 ft. 12.5 ft. 8.5 ft.
Answer and explanation:
Depending on the type and size of tent you wish to make, an average tent should consume more than 12.5ft of fabric. You would require more than 10 yards of fabric to make a small tent that an adult human being can fit in.
1 yard = 3 ft
And so you would require about 30 ft of fabric to make your tent. Therefore the options listed may not be enough fabric to make a tent

Step-by-step explanation:
Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45. Which equation represents this relationship?
Answer:
3x=38
Step-by-step explanation:
Given that,
Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45.
Let Annie's age is x.
Emily's age = 7+2x
ATQ,
The sum of their ages is 45.
x+7+2x = 45
Taking like terms together,
x+2x = 45-7
3x=38
Hence, this is the relation between their ages.
1. Line k is perpendicular to the graph 4x - 3y + 14 = 0 and passes through (-3,2). Find an equation in Standard
Form whose graph is line k.
Answer:
Step-by-step explanation:
any line k perpendicular to 4x-3y=14 is
3x+4y=a
∵ it passes through (-3,2)
so 3(-3)+4(2)=a
-9+8=a
a=-1
so reqd. eq. is 3x+4y=-1
You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days. You have 116 rooms available. What is your average occupancy for the past three nights?
Answer:
The average occupancy rate for the past three nights is of 86.49%.
Step-by-step explanation:
We want to find the average occupancy rate, as a percentage.
You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days.
So the mean number of rooms sold during the past 3 days is given by:
[tex]A = \frac{101 + 98 + 102}{3} = \frac{301}{3} = 100.33[/tex]
Average rate:
[tex]R = \frac{100.33*100}{116} = 86.49[/tex]
The average occupancy rate for the past three nights is of 86.49%.

What is the solution to the trigonometric inequality sin(x)>cos(x) over the interval 0<=x<=2piradians?
ANSWER: C
Answer:
x > π/4Step-by-step explanation:
Given the inequality expression
sin(x)>cos(x)
Divide both sides by cos(x)
sin(x)/cos(x)>cos(x)/cos(x)
tan(x) > 1
x > tan⁻¹1
x > 45⁰
x > π/4
Hence the required solution is x > π/4

Yes 35 48.5 12.5
No 120 56.9 11.9
answer : ( -12.968, -3.832 )
Step-by-step explanation:
To generate a 95% confidence interval
first step :
Assume population variance is equal we will calculate the number of degrees of freedom
df = n1 + n2 - 2 = 35 + 120 -2 = 153
second step:
Given : critical value = 0.05 , df = 153
hence Tc = 1.976
assuming the population variance is equal calculate pooled std as ( attached below )
Sp = 12.036
third step :
calculate the standard error
Se = [tex]Sp\sqrt{\frac{1}{n1} +\frac{1}{n2} }[/tex]
n1 = 35
n2 = 120
Sp = 12.036
hence Se = 2.312
final step
Compute the 95% confidence interval = ( -12.968, -3.832 )
attached below is the detailed solution

You go to the park on a windy day to fly a kite. You have released 40 feet of string. The string makes an angle of 36° with the ground. How high is the kite in the air?
Answer:
68ft
Step-by-step explanation:
Sin36=o/h = opposite / hypotenuse
x=40/Sin36
x=68
The kite in the air is 23.512 feet.
What is trigonometry ?Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
Given:
String length= 40 feet
Angle of elevation = 36
Now using concept of application of Trigonometry
sin 36= P/H
0.5878= P/40
P= 23.512 feet.
Hence, the kite in the air is 23.512 feet.
