A small airplane climbs at an
angle of 18° with the ground.
Find the horizontal distance it
has flown when it has reached an
altitude of 800 m.
a) 2,462 m
b) 260 m
c) 761 m
d) 2,588 m
e) 841 m
Answer:
Choice C, 761 m
Step-by-step explanation:
let horizontal distance be x
in the right triangle, cos= adj/hyp
cos(18)=x/800
x=cos(18)×800= 760.845≈ 761

Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532
Answer:
★ Given :
Cost of 50 chickens and 30 ducks = $ 550
Cost of 44 chickens and 36 ducks = $ 532
★ To find :
Cost of chicken and duck
★ Solution :
Assume :
Cost of chicken = x
Cost of duck = y
According to question :
50x + 30y = 550 ......(1)
44x + 36y = 532......(2)
1) - (2)
(50x + 30y) - (44x + 36y) = 550 - 532
50x + 30y - 44x - 36y = 18
6x - 6y = 18
6(x - y) = 18
x - y = 18/6
→ x - y = 3 ....(3)
In equation 1 ,
50 x + 30y = 550
taking 10 common
10(5x + 3y) = 550
5x + 3y = 550/10
5x + 3y = 55
by taking 3 common
3(5/3 x + y) = 55
by dividing 3 on both sides
5/3x + y = 55/3 .....(4)
(3) + (4)
x - y + 5/3 x + y = 3 + 55/3
x + 5/3 x = 64/3
8/3 x = 64/3
by multiplying 3 on both sides
8x = 64
x = 64/8
→ x = 8
→ Cost of chicken = $ 8 ..
by putting value of x in equation 3
x - y = 3
8 - y = 3
y = 8 - 3
→ y = 5
→ Cost of ducks = $5..

First off, the slope of f(x) is -4. It is in the form y=mx+b and m=-4.
For g(x), the slope can be calculated from any two points given. I willuse (1,9) and (3,21) because I like positive numbers. So, slope is rise over run and it is calculated from (y1-y0)/(x1-x0) This gives me (21-9)/(3-1) which is equal to 6. So adding the two slopes: 6+ (-4)=2
Find the Area of the below triangles #s 1 & 2 (Show all work)
Area =

B = 15 in.
Area =
2. H = 8 in.
B = 15 in.
Answer:
1) 30 in²
2) 60 in²
Step-by-step explanation:
a = (1/2)bh
----------------------
h = 4
b = 15
a = 1/2 * 4 * 15
a = 30 in²
----------------------
h = 8
b = 15
a = 1/2 * 8 * 15
a = 60 in²

This is a 30° 60° 90° triangle, so the rules below apply:
x is the short leg of the triangle, located across from the 30° angle. (In this problem, the short leg is labled b)
The hypotenuse leg is across from the right angle, and is always 2x (In this problem, the hypotenuse leg is labled c)
The long leg of the triangle is located across the 60° angle and is always x√3. (in this problem, the long leg is labeled a)

When n=343 college students are randomly selected and surveyed, it is found that x=110 own a car. Find a 99% confidence interval (CI) and margin of error (ME) for the true proportion of all college students who own a car.
Answer:
The margin of error will be "0.65". A further explanation is provided below.
Step-by-step explanation:
The given values are:
n = 343
x = 110
At 99% confidence level,
[tex]\alpha = 1-99[/tex]%
[tex]=1-0.99[/tex]
[tex]=0.01[/tex]
then,
[tex]\frac{\alpha}{2} =\frac{0.01}{2}[/tex]
[tex]=0.005[/tex]
or,
[tex]Z_{\frac{\alpha}{2} }=Z_{0.005}[/tex]
[tex]=2.576[/tex]
Now,
The point estimate will be:
⇒ [tex]\hat{P}=\frac{x}{n}[/tex]
⇒ [tex]=\frac{110}{343}[/tex]
⇒ [tex]=0.321[/tex]
or,
⇒ [tex]1-\hat{P}=1-0.321[/tex]
⇒ [tex]=0.679[/tex]
The margin of error will be:
⇒ [tex]E=Z_{\frac{\alpha}{2} }\times \sqrt (\frac{(\hat{P}\times (1 - \hat{P})) }{n} )[/tex]
On substituting the above values, we get
⇒ [tex]=2.576\times \sqrt{\frac{0.321\times 0.679}{343} }[/tex]
⇒ [tex]=2.576\times \sqrt{\frac{0.217959}{343} }[/tex]
⇒ [tex]=0.065[/tex]
hence,
⇒ [tex]\hat{P}-E<p<\hat{P}+E[/tex]
⇒ [tex]0.321-0.065<p<0.321+0.065[/tex]
⇒ [tex]0.256,0.386[/tex]

complete the table to show an equivalent ratio where the number of ears at the start of 100.
Answer:
60
Step-by-step explanation:
If Isabelle sells 150 out of 250 ears of corn. Then the percentage of the ears of corn she sold will be 60%.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Every morning she starts with 250 ears of corn.
On Saturday, Isabelle sells 150 out of 250 ears of corn.
Then the percentage of the ears of corn she sold will be
[tex]\rm P = \dfrac{150}{250} \times 100\\\\P = 15 \times 4\\\\P = 60 \%[/tex]
