Linda is paid double her normal hourly rate for each hour she works over 40 hours in a week. Last
week she worked 52 hours and earned $544. What is her hourly pay?
Answer:
her hourly pay is £8.50
Step-by-step explanation:
h= hourly pay
n = number of hours worked over 40 hours in a week
week pay = 40h + (n x 2 x h)
544 = 40h + 2nh
52 - 40 = 12, so n = 12
544 = 40h + 2 x 12 x h
544 = 40h + 24h
544 = 64h
544/64 = 8.5 h=8.5 (£8.50)
just to check:
£8.50 x 40 = £340
£8.50 x 2 x 12 = 204
340 + 204 = 544 yayy the answer is correct
hope this helps x

How many 45° angles would it take to turn in a complete circle
Answer: 8 45 degree angles
Step-by-step explanation:
A circle is 360 degress. 360 divided by 45 equals 8
Answer:
8
Step-by-step explanation:
a circle is 360°. to find how many 45° angles it would take to turn in a complete circle:
360°/45°=8
it would take 8 45° angles to turn in a complete circle

Are these triangles similar? Why?
A. Yes, SSS~ Postulate
B. Yes, SAS~ Postulate
C. Yes, AA~ Postulate
D. No, they are not similar.
Answer:
Step-by-step explanation:
<Q is common to both triangles.
130 / 40 = 3.25
Call DQ = x
40/130 = x / (x + 72) Cross multiply
40*(x + 72) = 130*x
40x + 2880 = 130x Subtract 40 x from both sides
2880 = 90 x Divide by 90
x = 32
(72 + 32)/32 = 104/32 = 3,25
The ratios are the same.
Therefore the triangles are similar by SAS

Please help me solve this
Answer:
7)
to work it out:
180-110= 70
because there are two unknown angle we're gonna assume they're both the same amount. So if they are both the same and equal then we need to half 70 which will be equal to the two sided. So. 70/2= 35
So the 2 x's = 35 each
8)
you need to put this all into an equation so:
7x-11 + 5x-2 + 2x-3 = 180 degrees
12x - 9 + 2x-3
10x + 6
Actual answer:
14x-16
Step-by-step explanation:
Solve the equations 2x + 2 = x + 9
Answer:
x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Given
2x + 2 = x + 9 ( subtract x from both sides )
x + 2 = 9 ( subtract 2 from both sides )
x = 7

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93?
Answer:
n = 50
Step-by-step explanation:
Let a be the first term and d be the common difference.
An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
[tex]a_n=a+(n-1)d[/tex]
According to the given condition,
[tex]a_2=3\\\\a_{10}=-13[/tex]
or
[tex]a+(2-1)d=3\\\\a+d=3\ ...(1)\\\\a+(10-1)d=-13\\\\a+9d=-13\ ...(2)[/tex]
Subtract equation (1) from (2).
a+9d-(a+d) = -13-3
8d = -16
d = -2
Put the value of d in equation (1).
a+(-2) = 3
a = 3+2
a = 5
Now,
[tex]a+(n-1)d = -93\\\\5+(n-1)(-2)=-93\\\\5-2n+2=-93\\\\7+93=2n\\\\2n=100\\\\n=50[/tex]
So, 50th term has the value of -93.
Triangle ABC has vertices A(-5, -1), B(5, -1), and C(0, -4). Is it scalene, isosceles or equilateral
Answer:
Isosceles Triangle
Step-by-step explanation:
Triangle ABC has vertices A(-5, -1), B(5, -1), and C(0, -4). Is it scalene, isosceles or equilateral?
We solve this question using vertices formula:
√(x2 - x1)² + (y2 - y1)² when given vertices: (x1, y1) and (x2 , y2)
For Side AB
A(-5, -1), B(5, -1)
AB = √(5 - (-5))² + (-1 -(-1))²
AB= √(5 + 5)² + (-1 + 1)²
AB = √10² + 0
AB = √100
AB = 10 units
For Side BC
B(5, -1), C(0, -4)
BC = √(0 - 5)² + (-4 -(-1))²
BC = √-5² + (-4 + 1)²
BC = √25 + -3²
BC = √25 + 9
BC = √34
For Side AC
A(-5, -1), C(0, -4).
AC = √(0 - (-5))² + (-4 - (- 1)²
AC = √5² + -3²
AC = √25 + 9
AC = √34
Therefore this triangle is an isosceles triangle because 2 of its sides (AC and BC ) are equal to one another

george has opened a new store and he is monitoring its success closely. He has found that this store’s revenue each month can be modeled by r(x)=x2+5x+14 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars. He has also found that his expenses each month can be modeled by c(x)=x^2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars.
the new store will sell 900 items in its fifth month in business
the store will have a profit of $900 after its fifth month in business
the store will have a profit of $5400 after its fifth month in business
the new store will sell 5400 items in its fifth month in business
Answer:
Step-by-step explanation:
The correct answer is that the new store will have a profit of $5400 after its fifth month.
Profit is given by subtracting revenue minus cost:
(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9
Using 5 for x,
(R-C)(5) = 9(5) + 9 = 45+9 = 54
This is in hundreds of dollars, so it represents $5400.

Answer:
-2
Step-by-step explanation:
You can see that when x goes up by 1, y goes down by 2. This means the rate of change is -2
Answer:
The rate of change is -2
Step-by-step explanation:
Take any two points from the graph. (0,-4) and (-2,0). Plug them into the equation y2-y1/x2-x1. In this case the equation would be 0--4/-2-0. Simplify this and get 0+4/-2-0. Simplify again and get 4/-2 which is -2
Therefore the rate of change is -2

Help I’m confused big points to who can solve this
Answer:
n = 2
Step-by-step explanation:
Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4
This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.
We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.
-n = -2,
n = 2
