bird is flying directly above a tree you are standing 40 feet away from the tree the angle of elevation to the top of the tree is 32 degrees and the angle of elevation to the bird is 42° how far above the tree is the bird
Answer: 11 ft
Step-by-step explanation:
Given
The boy is standing 40 feet away from the tree
the angle of elevation for the tree is [tex]32^{\circ}\\[/tex]
the angle of elevation for the bird is [tex]42^{\circ}\\[/tex]
using figure
[tex]\frac{h+x}{40}=\tan 42^{\circ}\\h+x=40\tan 42^{\circ}\ldots (i)\\Now,\\\tan 32^{\circ}=\frac{h}{40}\\h=40\tan 32^{\circ}[/tex]
Put the value of h in equation (i)
[tex]40\tan 32^{\circ}+x=40\tan 42^{\circ}\\x=40[\tan 42^{\circ}-\tan 32^{\circ}]\\x=40[0.9-0.624]=0.276\times 40=11.04\ ft[/tex]

Rasheed is buying wings and quesadillas for a party. A package of wings costs $8. A package of quesadillas costs $10. He must spend no more than $160. Rasheed’s freezer will hold a maximum of 20 packages of wings and quesadillas.
If Rasheed buys 7 packages of wings, what is the maximum number of packages of quesadillas he can buy?
Answer:
10 is maximum of packages of quesadillas.
Step-by-step explanation:
x= number of wings
y= number of quesadillas
x+y=20
8x+10y=$160
if x=7
then 7+y=20
20-7=14=y
14*10=140
8*7=56
Rasheed can't buy 20 packages, since it'll go over his budget.
So 160-56=104
And 104/10= 10 minimum
10*10=100
100+56=160
So he can buy 10 packages of quesadillas.

Jasmine purchased a television that was 45% off the regular price of $1290. If an 8% sales tax was added to the cost of the television, what was the total price Jasmine paid for the television? (Round to the nearest cent)
Answer:
$766.26 please mark brainliest if satisfied
Step-by-step explanation:
1290 times 0.45 equals 580.50
1290 minus 580.50 equals 709.50
709.50 times 0.08 equals 56.76
709.50 plus 56.76 equals 766.26
Answer:
I believe it would be 2216.7. if you rounded to the nearest cent it would be 2217. hope that helps :) but I'm not very smart so don't take me up on that

Answer:
a) The required terms are:
7,10,13,16,....34
b) The required terms are:
-1,3,7,11,...35
Step-by-step explanation:
For each question we need to find the first 4 terms and the 10th term.
a) 3n + 4
Put n = 1, 2 ,3, 4 for first 4 terms, and 10 for 10th term
Put n = 1, 3(1)+4 = 3+4 = 7
Put n = 2 , 3(2)+4 = 6+4 = 10
Put n =3 , 3(3)+4 = 9+4 = 13
Put n = 4, 3(4) + 4 = 12+4 = 16
Now, Put n= 10 3(10)+4 = 30+4 = 34
So, the required terms are:
7,10,13,16,....34
b) 4n -5
Put n = 1, 2 ,3, 4 for first 4 terms, and 10 for 10th term
Put n = 1, 4(1)-5 = 4 - 5 = -1
Put n = 2 , 4(2)-5 = 8-5 = 3
Put n =3 , 4(3)-5 = 12-5 = 7
Put n = 4, 4(4) -5 = 16-5 = 11
Now, Put n= 10 4(10)-5 = 40-5 = 35
So, the required terms are:
-1,3,7,11,...35

I’ll give you brainly pls I really need the answer
Step-by-step explanation:
HERE,
[tex]\angle{PQR=20+2x }[/tex] ⠀
[tex]\angle{ QRS=6x }[/tex] ⠀
we know that,
sum of consecutive angle of a parallelogram =180
so,
According to the question,
[tex]\angle{PQR}+\angle{QRS}=180[/tex] ⠀
[tex]\tt{20+2x+6x=180 }[/tex] ⠀
[tex]\tt{8x+20=180 }[/tex] ⠀
[tex]\tt{8x=180-20 }[/tex] ⠀
[tex]\tt{8x=160 }[/tex] ⠀
[tex]\tt{x=\dfrac{160}{20} }[/tex] ⠀

If we have six decisions to make and 2 choices for each decision, how can we represent the number of potential outcomes?
A 6 to the power of 2
B 2 to the power of 2
C 6 to the power of 6
D 2 to the power of 6
Answer:
A
Step-by-step explanation:
because for each 6 you have 2
We can represent the number of potential outcomes by 2 to the power 6.
What is permutation and combination?'In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order.
The combination is a way of selecting items from a collection, such that the order of selection does not matter.'
'The power of a number says how many times to use the number in a multiplication. Powers are also called exponents or indices.'
According to the given problem,
We can assume, for two choices, we have one decision.
This can be represented as [tex]2^{1}[/tex].
Since, we have six decisions,
Representation of the potential outcomes ⇒[tex]2^{1}+2^{1} +2^{1} +2^{1} +2^{1} +2^{1}[/tex]
= [tex]2^{6}[/tex]
= [tex]64[/tex]
Hence, the representation of the number of potential outcome is 2 to the power 6.

A student tried to solve the following equation but made a mistake.
Step 1: 4 – 8x = -28
Step 2: -8x = -24
Step 3: x = 3
What mistake did the student make?
9514 1404 393
Answer:
in Step 2, the student added 4 on the right and subtracted 4 on the left
Step-by-step explanation:
In Step 2, the student subtracted 4 on the left side of the equation, but incorrectly added 4 on the right. (The same operation needs to be performed on both sides of the equation.) The correct step 2 would be ...
-8x = -32 . . . . correct step 2
x = 4 . . . . . correct step 3
