Answer/Step-by-step explanation:
You take one side and use that.
since you split it in half divide the bottom number by 2.
8/2 -> 4
ok now you need to know that since there is 2 angles the same it is a
30-30-60 triangle.
and it goes x,2x, x\(\sqrt[n]{3} \)
you have our 2 sides so then you would just place the x= \(\sqrt{4} \) and simplify it down
so the answer would be D: X=2

1000000 x 1000000= what?
Answers
Answer:
1000000000000
Step-by-step explanation:
1000000x1000000=1000000000000
The solution of the expression 1000000 x 1000000 in exponential form is \(10^{12}\).
A collection of constants, variables connected using one or more arithmetic operator is called an expression.
Example = 4y, 3x+4.
The way of writing or expressing a number in powers is called exponent.
Example: \(3^2\)
Here, 3 is the base and 3 is the power.
The given expression can be written in the index or exponential form as:
1000000 x 1000000 = \(10^6 \times 10^6\)
Since, the given exponent has the same base.
So, using the law of exponent, it can be written as:
\(a^m + a^n = a^{(m+n)\)
\(10^6 \times 10^6 = 10^{(6+6)}\)
= \(10 ^{12}\)
Thus, the solution of the expression 1000000 x 1000000 in exponential form is \(10^{12}\).

Answers
Answer:
$292.50
Step-by-step explanation:
Equation - A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.5%/100 = 0.025 per year.
Solving our equation:
A = 260(1 + (0.025 × 5)) = 292.5
A = $292.50
The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.

Answers
Answer:
D.i belive if nor sryyy
Step-by-step explanation:
Answer:
D
Cost of one scarf= $7
Cost of one hat= $4
Step-by-step explanation:
Let s represents the cost of scarfs
and h represents the cost of hats.
Cost of four scarfs and six hats is $52.00
i.e. 4s+6h=52
Cost of two hats is $1.00 more than the cost of one scarf.
i.e. 2h=s+1
s=2h-1
substituting s in 4s+6h=52
4(2h-1)+6h=52
8h-4+6h=52
14h=56
h=4
s=2h-1
s=8-1
s=7
Hence,
Cost of one scarf= $7
and Cost of one hat= $4
Triangles ABC and DEC are similar. Side DE is 1.8 feet, side EC is 4 feet, and side BE is 0.8 foot.
Part A: Describe how to draw triangles ABC and DEC separately. Be sure to give the lengths of sides BC, DE, and EC in the description.
Part B: Find side AB. Show each step of your work.
Answers
The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively. The length of side \(AB\) is approximately \(3.36\) feet.
What is the line segment?Part A:
To draw triangles \(ABC\) and \(DEC\) separately, follow the steps below:
Draw a straight line segment DE with length \(1.8\) feet.
From point D, draw a line segment DC perpendicular to DE with length 4 feet.
Connect point E and point C with a straight line segment EC.
From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.
Draw a straight line segment BC that intersects line segment DC at point A.
Connect point A and point B with a straight line segment AB.
The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively.
Part B:
Since triangles \(ABC\) and \(DEC\) are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:
\(AB/DE = BC/EC\)
Substituting the given values, we get:
\(x/1.8 = BC/0.8\)
Solving for BC, we get:
\(BC = 0.8x/1.8\)
Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:
\(BC^2 + EC^2 = DE^2\)
Substituting the given values, we get:
\((0.8x/1.8)^2 + 4^2 = 1.8^2\)
Solving for x, we get:
\(x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8\)
\(x \approx 3.36 feet\)
Therefore, the length of side \(AB\) is approximately \(3.36\) feet.

Evander would like to buy a new hockey stick. He earns $15 time he cuts the grass in his neighborhood. Because of his busy schedule, he can cut grass on Saturdays and Sundays. Evander is responsible for paying $10/week toward his cell phone bill. He also enjoys chocolate and has a $2 bar least twice weekly. Every time he cuts two lawns, he has to fill up the lawnmower with $5 worth of gas.
If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
When could Evander save enough for the stick if he stopped eating chocolate bars?
When could Evander save enough for the stick if he was able to cut another lawn on Wednesday nights AND stopped eating chocolate?
Answers
Answer/Step-by-step explanation:
If he cuts one lawn each day on the weekend, how much money will he have after he has paid for gas, chocolate, and his cell phone?
earns - 30 pays - $10pb $2b $5(this is for the 2 days)
SO he gets 30 but spends 19,
Meaning he gets $11 proffit.
30-19 = $11
Evander would like the same stick that Alexander Ovechkin uses. The regular price is $229.99 (including taxes). How long will it take Evander to save enough money to buy the stick?
He makes $11 every week. so 229.99/11 = 20.9, so it will take him 21 weeks to get it.
When could Evander save enough for the stick if he stopped eating chocolate bars?
Ok so he would be getting 2 dollars more so that would make it $13. So 229.99/13 = 17.69, meaning it will take 18 weeks to get it.

A manufacturer inspects 50 computer monitors and finds that 45 have no defects. What is the experimental probability that a monitor chosen at random has no defects?
Answers
Answer:
The experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials or observations.
In this case, the event is choosing a monitor with no defects, and the number of times the event occurs is 45. The total number of monitors is 50.
So, the experimental probability of choosing a monitor with no defects is:
45/50 = 0.9
Therefore, the experimental probability that a monitor chosen at random has no defects is 0.9 or 90%.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

When I put this into y2-y1/x2-x1 (equation to find slope) I did the coordinate pairs (3,-9) and (4,-11). When you plug it in it’s -11+9/4-3. This gets you -2/1, which is -2. That’s your slope. Then, in order to get the y-intercept, you can use any of those pairs. I did -9 = 3(-2) + b. -9=-6 + b and in the end this gets you -3 = b. So the full equation is y = -2x - 3.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
