Answer : 14hours
Step-by-step explanation:
If a camera costs 150 dollars and she already has 25 dollars, she needs 125 dollars more
9x14=126 so she needs to works 14 hours
The number of hours needed to babysit in order to purchase the camera is 14.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amount in her account = $25
Amount earned per hour = $9
The expression to find the number of x hours to buy the camera.
25 + 9x = 150
9x = 150 - 25
9x = 125
x = 13.89
x = 14
Thus,
The number of hours needed is 14.

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.

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.
