Answer:
Solution:
The greatest of Winnie's even numbers is $2\times 30 = 60,$ so her sum is
\[2+4+6+\cdots + 58 + 60.\]For Grogg's sum, there are five odd numbers between $0$ and $-10$, five between $-10$ and $-20$, and so on, so Grogg's sum is
\[(-1)+(-3)+(-5)+\cdots+(-57)+(-59).\]
We could compute these sums separately and find their difference, but instead, we'll look for a clever way to regroup to compute the difference
\[(2+4+6+\cdots +58+60)-((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Noting that Winnie's list steps up by 2 at each term while Grogg's steps down by 2 at each step, we write Winnie's list backwards, so that each list goes down by 2 at each step:
\[(60+58+56+\cdots + 4+2) - ((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Now, we see that the difference between a term in Winnie's backwards list and the corresponding term in Grogg's list is always the same:
\begin{align*}
60-(-1) &= 61,\\
58-(-3) &= 61,\\
56-(-5) &=61,\\
\vdots&\\
2-(-59) &= 61.
\end{align*}There are 30 such differences, so Winnie's sum is $30\times 61 = \boxed{1{,}830}$ greater than Grogg's sum.

Which of the following is the equation of a line perpendicular to the line y =
-10x+1, passing through the point (5,7)?
Answer: The answer is C.
Step-by-step explanation: This is because when you solve you get y=1/10x+6.5 this graph runs through the point (5,7) and is perpendicular to y=-10x+1. In order for two equations to be perpendicular their slopes will be the opposite.
Find sin (E) given the triangle.
Someone pls help me wit this I’m so confused
Answer: 75.75°
Step-by-step explanation:
Sine is the opposite of the angle divided by the hypotenuse. The opposite side of the angle is 12.6 and the hypotenuse is 13.
sin(Ф) = 12.6/13
Take the inverse sine of both sides, this requires a calculator.
Ф = 75.75°

PLEASE HELP ME ANSWER The probability that Scott will be late for work is 0.15. In a year Scott works for 240 days. Work out the expected number of days that he will be late......
Answer:
36 days
Step-by-step explanation:
Given
[tex]p = 0.15[/tex] -- probability of coming late to work
[tex]n = 240[/tex] -- number of days
Required
Determine the expected number of days of coming late (E(x))
This is calculated using:
[tex]E(x) = np[/tex]
[tex]E(x) = 240 * 0.15[/tex]
[tex]E(x) = 36[/tex]
The expected number of days is 36
Find the mean of the data 18,36,24,36,30,36
Answer:
30
Step-by-step explanation:
To calculate the mean, add up all the numbers in the data and divide the sum by the number of numbers in the data.
(18+36+24+36+30+36)/6 = 30.
Answer:
30
Step-by-step explanation:
To find mean, add up all the numbers, then divide by how many numbers there are:
18 + 36 + 24 + 36 + 30 + 36/6
180/6 = 30
Hope this helps :)

Work out the size of angle
X.
X Х
33°
20°
165°
Answer:
142 degrees
Step-by-step explanation:
The sum of angle in a quadrilateral is 360 degrees
33 + 20 + 165 + X =360
53 + 165 + X = 360
218 + X = 360
X = 360 - 218
X = 142
Hence the size of angle X is 142 degrees

Amy and three of her friends went to lunch. The total bill was $54.00. If they wanted to leave a 20% tip how
much more is added tot he bill?
If the girls split the bill evenly, how much does Amy pay?
Answer:
$16.20
Step-by-step explanation:
Bill: $54.00
Tip: 20%
People: 4
To figure out 10% of the bill, you need to move the decimal point over to the left one place: $5.40
10%: $5.40
5.40 times 2 = $10.80
54.00 + 10.80 = 64.80
Grand Total= $64.80
Since there are 4 people, we need to divide by 4:
64.80 divided by 4 = $16.20
This recipe makes 18 shortbread fingers.
Rose follows this recipe, but only wants to make 3 fingers.
How much of each ingredient does she need?
Recipe: Makes 18
120 g butter
60 g sugar
180 g flour
(I don't know if this is the method you are supposed to use, but I believe you will still get the same answer!)
Answer: 20 g butter, 10 g sugar, 30 g flour
Step-by-step explanation: First off, if we look at 3 and 18, you notice that three is a factor or 18, going into the number 6 times.
So, if you are making 6 times less of the original amount, divide each measurement by six to give you your answer.
120/6 = 20
60/6 = 10
180/6 = 30
Solve 64 = h + 30.
K=?
Answer:
h = 34
Step-by-step explanation:
64=h+30
Step 1: Flip the equation.
h+30=64
Step 2: Subtract 30 from both sides.
h+30−30=64−30
h=34
