Which set of integers is ordered from least to greatest -13 , 4, 0, -8 -5 , -2, 3, 1 -12 , -18 , -4 , 7 -15, 6 , -9 , -21
Given:
The set of integers in the options.
-13 , 4, 0, -8
-5 , -2, 3, 1
-12 -18 , -4 , 7
-15, 6 , -9 , -21
To find:
The set of integers that is ordered from least to greatest.
Solution:
We know that the larger negative value is the smaller value and the larger positive value is the greater value.
Ordered from least to greatest means first we need to write the smallest value, write the value larger than and the greatest value occurs at the end.
In option A, we have -13 , 4, 0, -8. Here, 4>0. So, the option A is incorrect.
In option B, we have -5 , -2, 3, 1. Here, 3>1. So, the option B is incorrect.
In option C, we have -12 -18 , -4 , 7 Here, -12>-18. So, the option C is incorrect.
In option D, we have -15, 6 , -9 , -21. Here, 6>-9. So, the option D is incorrect.
Therefore, all the options are incorrect.

Amelia invests money in an account paying simple interest. She invests $180
and no money is added or removed from the investment. After one year, she
has $187.20. What is the simple percent interest per year?
Answer:
4%
Step-by-step explanation:
100% represents the starting balance: $180.
Method 1
Express the ending balance as a percentage of the starting balance:
$180
1.04
1.04 times 100=
1.04×100=
104%
Subtract the starting 100% to get the percent interest:
4%
Method 2
$187.20−$180=
$7.20
$180
$7.20
0.04
0.04 times 100=

Solve for n.
7n - 4 = 317
n =
Step-by-step explanation:
[tex]7n - 4 = 317 \\ 7n = 317 + 4 \\ 7n = 321 \\ n = \frac{321}{7} \\ n = 45 \frac{6}{7} [/tex]
Answer:
[tex]n = \frac{321}{7} [/tex]
Step-by-step explanation:
1) Add 4 to both sides.
[tex]7n = 317 + 4[/tex]
2) Simplify 317 + 4 to 321.
[tex]7n = 321[/tex]
3) Divide both sides by 7.
[tex]n = \frac{321}{7} [/tex]
Therefor, the answer is n = 321/7 and in decimal form it would be, 45.857143.

Debbie is ordering a breakfast special at a diner that comes with eggs, bread, and a drink. The special offers the following options:
• The eggs can be scrambled or fried.
• The bread options are a biscuit, a slice of toast, or a bagel.
• The drinks options are orange juice, apple juice, coffee, or tea.
• Debbie will randomly choose each option in the breakfast special.
What is the probability Debbie
will choose fried eggs, toast,
and either coffee or tea?
A. 1/12
B. 4/9
C. 4/5
D. 1/24
Answer:
The probability Debbie will choose fried eggs, toast, and either coffee or tea is;
A. 1/12
Step-by-step explanation:
From the question, we have;
The number of options for preparing the eggs = 2 options
Therefore, the probability of either egg option chosen = 1/2
The number of options for the type of bread = 3
Therefore, the probability of either bread option chosen = 1/3
The number of options for the drink = 4
Therefore, the probability of either drink option chosen = 1/4
We add probabilities connected with an 'or' statement and multiply probabilities connected with an 'and' as follows;
The probability for Debbie to choose either coffee or tea = 1/4 + 1/4 = 1/2
Therefore, the probability Debbie will choose fried eggs, (and) toast, and either coffee (or) tea, P is given as follows;
P = 1/2 × 1/3 × 1/2 = 1/12
The probability Debbie will choose fried eggs, toast, and either coffee or tea = 1/12.

£25 = 700 rubles, how many £ are in 1,260 rubles?
£
Answer:
45
Step-by-step explanation:
25 = 700
Y = 1260
Now you need to do cross multiplication .
25 X 1260=700Y
Since it's in a multiplying form you can simplify by dividing 700 by 25
1260=700Y/25
1260=28Y
Y=45

As the first of the Curie family legacy of five Nobel Prizes, she was the first woman to win a Nobel Prize, the first and the only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two scientific fields. She was the first woman to become a professor at the University of Paris in 1906.[4]

4 A triangle with a height of 3 cm and a base
of x cm is the result of reducing each
dimension by a scale factor of one-third.
The area of the original triangle is
162 cm². What was the original length of
the base?
Answer:
L = 36
Step-by-step explanation:
"A triangle with a height of 3 cm and a base of x cm is the result of reducing each dimension by a scale factor of one-third"
We are looking for the original. This triangle was reduced by 1/3, so we would have to mulitply by 3 to get the original triangle measurements.
height = 3 x 3 = 9
length = x * 3
"The area of the original triangle is 162 cm²."
Area = Base x Height/2
162 = (x*3) * 9/2
324 = (x*3)*9
36 = x*3
x = 12
What was the original length of the base?"
Length = x * 3
= 12 * 3
Length = 36

Find m∠A and m∠B =
Answer:
96 for b 90 for a
Step-by-step explanation:
You are trying to heat up a cup of water with a butane lighter.
1) How much heat is transferred to the water if 200 g of water with a specific heat capacity of 4.184Jg°C changes from 22.3ºC to 35.7ºC? Answer in kJ.
2) If you burn 0.23 g of butane, what is the heat of combustion of butane in kJ/g?
Answer:
Step-by-step explanation:
Remark
The formula for this is
Heat = m * c * Δt
Givens
Heat = unknown
m = 200 grams
c = 4.184 Joules / grams oC
Δt = the change in temperature = 35.7 - 22.3 = 13.4
Solution
Heat = 200 * 4.184 * 13.4
Heat = 11213 Joules
Heat = 11.2 Kj
It's hard to get the correct number of sig digs because the 200 is not qualified in any way.
Part 2.
This can really puzzle you until you know that heat given up = the heat taken on. The heat taken on was 11.2 Kj. The Butane lighter must have given that heat on.
Heat of Combustion = Heat Given Up / Number grams burned.
Heat of Combustion = 11.2 Kj / 0.23 grams
Heat of Combustion = 48.8 Kj / gram

Note however that the shape of the diagram does not match the numbers on it. So either it is poorly drawn, or I am misinterpreting the numbers. It seems pretty clear though that the image is incorrect, as the two segments both marked as being 25 units long are represented at different lengths.
Step-by-step explanation:
The image here does not fit the numbers. Note that the bottom triangle has two sides with given lengths of 25 units, but they are drawn as different lengths.
Let's plough on though, and find a better image of what that shape would be.
Starting with the bottom triangle:
Given that the two sides of the bottom triangle are both 25 units in length, we know that it is an isosceles triangle (despite its depiction otherwise). Because of that, we know that the two bottom angles are equal. We already know that the top corner is 90°, and that the sum of the angles in a triangle must be 180° This means that the two bottom angles (again, contrary to how its drawn) are both equal to 45°
Now that we have that information, we can look at the over triangle. We know that the bottom right corner is 45°, and that the bottom left is 90°. That tells us that the top angle is also 45°.
With that said, we can redraw the image with the proper proportions. See the attached image.
That very much simplifies things. The line separating the triangles bisects the hypotenuse of the larger triangle, meaning that x is also equal to 25.
To be sure of that though, we can prove it another way. Given that the bottom two corners are both 45, we can use the sine rule to measure x. The sine rule states that the sine of each angle in a triangle has the same ratio to their opposite sides. Usually expressed as:
[tex]\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}[/tex]
where a, b and c are the side lengths, and A, B and C are the angles of the corners opposite those sides.
With that we can take the two parts of the overall triangle's hypotenuse, 25 and x, and say that each of those divided by the sine of the angle opposite them is equal to each other:
[tex]\frac{x}{\sin 45} = \frac{25}{\sin 45}[/tex]
This turns out to be very easy to solve, as both sides have the same denominator. As a result, we can just multiply both sides by sin 45, giving us:
x = 25.
