A number is called evil if it has 666 in it. How many 7 digit numbers are evil?
Step-by-step explanation:
There are 5 different positions of 666:
666////
/666///
//666//
///666/
////666
The forward dashes represent any number from 0 to 9.
Case 1: "666////"
Number of ways = 10⁴ = 10,000.
Case 2: The other positions.
Since the 1st forward dash cannot be 0 (leading digit),
Number of ways for each position = 9 * 10³ = 9,000
Number of ways for all 4 positions = 9,000 * 4 = 36,000.
Total evil numbers = 10,000 + 36,000 = 46,000.

Answer:
134.5 degree
Step-by-step explanation:
first find the remaining side of a triangle
BY using cosine rule
C^2=A^2+B^2-2ABcosx
apply square root both sides
√c^2 =√[4^2+10^2-2(4)(10)cos29]
C=√(116-69.96958)
C=√46.03
C=6.8
Now find angle using cosine rule
C^2=A^2+B^2-2ABcosx
10^2=4^2+6.78^2-2(4)(6.78)cosx
100=16+45.9684-54.24cosx
100=61.9684-54.24cosx
100-61.9684=-54.24cosx
(38.0316)/-54.24=(-54.4cosx)/-54.24
-0.70117=cosx
X= cos inverse of -0.70117
x=134.5 degree

Which number has the largest absolute value,-2 or -3
Answer:
3
Step-by-step explanation:
The answer is 3 because absolute value is the distance away from zero so, -2 is 2 away from zero and -3 is 3 away from zero. Therefore, -3 has the largest absolute value.

Answer:
The equation of the line is;
y = 3x + 18
Step-by-step explanation:
We want to write the equation of the line through (-9,-9) and (-6,0)
we start by calculating the slope of the line
m = (y2-y1)/(x2-x1) = (0+ 9)/(-6+9) = 9/3 = 3
The general equation of the line is;
y = mx + c
y = 3x + c
To get c, we use any of the points
we substitute for example -6 for x and 0 for y
0 = 3(-6) + c
c = 0 + 18 = 18
So the equation of the line is;
y = 3x + 18
Answer:
3x+18

A farmstand sells apples, a, for $4 a bucket; peaches, p, for $6 A bucket; and strawberries, s, for $9 a bucket. The stand earn $229 in revenue last month. The stand sold half as many strawberry buckets as peach buckets, and eight were apple buckets then peach buckets. Using the substitution method how many apples peaches and strawberries did the farmstand sell?
A. a=10; p=18; s=9
B. a=4; p=6; s=9
C. a=18; p=10; s=9
D. a=9; p=18; s=10
Answer:
A.
Step-by-step explanation:
process of elimination. They sold half as many strawberries as peaches.
Jacob is a salesperson who sells computers at an electronics store. He makes a base pay amount each day and then is paid a commission as a percentage of the total dollar amount the company makes from his sales that day. The equation P=0.025x+95P=0.025x+95 represents Jacob's total payments on a day on which he sells xx dollars worth of computers. What is the y-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
The y-intercept of the function is 95 which represents the base pay Jacob makes regardless of computer sales.
Step-by-step explanation:
Jacob would make $95 even when selling $0 worth of computers, meaning 95 represents Jacob's base pay rate, the amount he is guaranteed to make regardless of how many dollars worth of sales he makes that day.
Have a good day :)
The y-intercept of the equation P =0.025x + 95 is 95 and it is representing the base pay of the salesperson of the day.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given,
The total amount of sales person,
P = 0.025x + 95
Here, x is the number of sales on which 2.5% he got.
At x = 0
P = 0 +95 = $95
Now, 95 is the fixed price therefore, it will be the base pay of the salesperson.
Hence "The y-intercept of the equation P =0.025x + 95 is 95 and it is representing the base pay of the salesperson of the day".

x² + 3x – 5= 0
Answer:
[tex]x = \dfrac{-3 \pm \sqrt{29}}{2}[/tex]
Step-by-step explanation:
x² + 3x – 5= 0
-5 = -5 * 1 = -1 * 5
-5 + 1 = -4
-1 + 5 = 4
To factor, we need two integers that multiply to -5 and add to 3. There are no such integers, so the trinomial is no factorable. We use the quadratic formula.
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \dfrac{-3 \pm \sqrt{3^2 - 4(1)(-5)}}{2(1)}[/tex]
[tex]x = \dfrac{-3 \pm \sqrt{9 + 20}}{2}[/tex]
[tex]x = \dfrac{-3 \pm \sqrt{29}}{2}[/tex]
