PLEASE HELP ME ASAP ITS DUE SOON EXPLAIN YOUR ANSWER PLSSS

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=

0.04×100=

4%

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

Answer:

[tex](3x-y)(x+y)^2[/tex]

Step-by-step explanation:

[tex]3x^3-x^2y+6x^2y-2xy^2+3xy^2-y^3[/tex]

Multiply and combine like terms.

[tex]3x^3+xy^2-y^3+5xy^3[/tex]

Consider [tex]3x^3+xy^2-y^3+5xy^3[/tex] as a polynomial over variable x.

[tex]3x^3+5xy^2+y^2x-y^3[/tex]

Find one factor of the form kx^m +n, where kx^m  divides the monomial with the highest power 3x^3  and n divides the constant factor −y^3 . One such factor is 3x−y. Factor the polynomial by dividing it by this factor.

[tex](3x-y)(x^2+2xy+y^2)[/tex]

Consider [tex]x^2+2xy+y^2[/tex]. Use the perfect square formula, [tex]a^2+2ab+b^2[/tex] = [tex](a+b)^2[/tex], where a=x and b=y.

[tex](x+y)^2[/tex]

Rewrite the complete factored expression.

Answer:

I think its c!!!!!!!!!!!!!!!!!

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

Answer:

Marie Skłodowska Curie (born Maria Salomea Skłodowska (Polish: [ 7 November 1867 – 4 July 1934), was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. 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]

Answer:

is it 3,4

Step-by-step explanation:

sorry if im wrong  i tried.

Answer:

we have:

AMC = 2ABC

=> 10x - 12 = 2(4x + 6)

<=> 10x - 12 = 8x + 12

<=> 2x = 24

<=> x = 12

with x = 12 => ABC = 4.12 + 6 = 48 + 6 = 54⁰

Answer:54

Step-by-step explanation:

Answer:

The answer is b: 25

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.

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.

Answer:

Step-by-step explanation:

2+2 = 4

1+1 = 2

5+10 = 15

q+3 = 21, q = 21-3 = 18

Or if you meant all of them added together is 21, 2+2+1+1+5+10+q+3=21

q = -3

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

Answer:

[tex]\boxed{\boxed{\sf x=\frac{\sqrt{217} +2}{3} }\:or\: {\sf\boxed{\sf x=\frac{2-\sqrt{217} }{3} } }}[/tex]

Step-by-step explanation:

[tex]\boxed{\sf Quadratic \:equation}[/tex]

*All equations of the form ax^2+bx+c=0 can be solved using the Quadratic Formula. *

[tex]\boxed{\sf \square \: \:\frac{-b\pm \sqrt{b^2-4ac}}{2a}}[/tex]

The Quadratic Formula gives two solutions, one when ± is addition and one when its subtraction.

________________________________

[tex]\boxed{\sf 3x^2-4x-71=0}[/tex]

This equation here is in the standard form: ax^2+bx+c=0.

Substitute 3 → a, -4 → b, -71 → c.

[tex]\sf x=\cfrac{-\left(-4\right)\pm \sqrt{\left(-4\right)^2-4\times \:3\left(-71\right)}}{2\times \:3}[/tex]

→ Square -4, and then multiply -4 × 3= :

[tex]x=\cfrac{-(-4)\pm \sqrt{16+12(-71)} }{2\times 3}[/tex]

Multiply -12 × -71 = 868, then Add 16+852= 868

[tex]\sf x=\cfrac{-(-4)\pm 2\sqrt{217} }{2\times 3}[/tex]

Take the Square root of 868 2√(217).

* the opposite of -4 → 4.

[tex]\sf x=\cfrac{4\pm 2\sqrt{217} }{2\times 3}[/tex]

Multiply 2 × 3 = 6

[tex]\sf x=\cfrac{4\pm 2\sqrt{217} }{6}[/tex]

Now, we'll solve the equation when ± is plus.

→ Add 4+ 2√(217).

→ Divide 4+ 2√(217 ) by 6.

[tex]\boxed{\sf x=\frac{\sqrt{217} +2}{3} }[/tex]

Now, we'll solve the equation when ± is minus.

→ Subtract 2√(217) from 4.

→ Divide 4 - 2√(217) by 6.

[tex]\boxed{\sf x=\frac{2-\sqrt{217} }{3} }[/tex]

Answer:

96 for b 90 for a

Step-by-step explanation:

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.
