An angle measures 150°. What is the measure of its supplement?
Answer:
The supplement is = 180-150 i.e30
Step-by-step explanation:
Let the another Angle be x then

Answer:
Step-by-step explanation:
!pic attached!Earl and Ray run competing carpet-cleaning services. Earl charges $50 for a house call and $40 per carpet cleaned. Ray charges the
same amount per carpet cleaned, but his total cost is always $30 less than Earl's. Which equation expresses the total cost, t, for Ray to
clean as a function of carpets cleaned, c?
Answer:
t= 20+40c
Step-by-step explanation:
Given that Ray's total cost is always $30 less than Earl's and they charge the same amount per carpet cleaned, the difference is in the amount charged for a house call and to find that amount you have to subtract 30 from the amount Earl's charges:
50-30=20
This means that Ray charges $20 for a house call and $40 per carpet cleaned. According to this, the equation would indicate that the total cost for Ray is equal to the amount he charges for a house call plus the price per carpet cleaned for the number of carpets cleaned, which would be:
t= 20+40c, where:
t is the total cost
c is the number of carpets cleaned

Step-by-step explanation:
Ella wants to buy apples and strawberries to make a fruit tart. Apples cost 3.50 per pound and strawberries cost 3.75 per pound. How many pounds of fruit does she buy if she buys 0.5 pounds of apples and 1.5 pounds of strawberries? How many pounds of fruit does she buy if she buys x pounds of apples and y pounds of strawberries?
Answer:
2 pounds of fruit
x+y pounds of fruits
Step-by-step explanation:
The first questions asks for total amount of fruit she bought. Before that, it stated, she bought .5 pound and 1.5 pounds of apples and strawberries. The equation would be 1.5+.5= 2. The next question is asking for the total amount of fruits if X was total pounds of apples while Y was total pound of strawberry. It is again asking for the total amount so the equation would be x+y= total.

Given:
The parent function is
[tex]f(x)=x^2[/tex]
The graphs of f(x) and g(x) are given.
To find:
The function g(x).
Solution:
From the given graph it is clear that the graph of f(x) is reflected over the x-axis and shifted 3 units down to get the graph of g(x).
The translation is defined as
[tex]g(x)=kf(x+a)+b[/tex] .... (1)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k. If k<0, then the graph of f(x) reflected over the x-axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
From the given graph it is clear that the graph of f(x) is reflected over the x-axis and shifted 3 units down to get the graph of g(x). So, k=-1, a=0 and b=-3.
[tex]g(x)=(-1)f(x+0)+(-3)[/tex]
[tex]g(x)=-f(x)-3[/tex]
[tex]g(x)=-x^2-3[/tex] [tex][\because f(x)=x^2][/tex]
Therefore, the required function is [tex]g(x)=-x^2-3[/tex]. So, the correct option is B.

thirteen states share a border w canada
There are 20 states that share the border with Canada.
What is subtraction?Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.
Given:
There are 50 U.S. states.
Seven twenty-fifths of the state share a land border with Canada or Mexico.
That means,
7[tex]\frac{20}{5}[/tex]
= 7 x 4
= 28
a number of 28 states share the border with Canada or Mexico.
Of those 2/7 share a border with Mexico,
that means, the number of,
= 28 - 28 x 2/7
= 28 - (4 x 2)
= 28 - 8
= 20 states share the border with Mexico.
Therefore, the required number is 20.
