Please help me I don’t understand what I’m supposed to do ! Unit 1 - Triangle Congruence
State if the two triangles are congruent. If they are, state how you know.

Given:

Two ratios 2:x and 12:18 are equivalent.

To find:

The value of x.

Solution:

We have,

[tex]2:x\equiv 12:18[/tex]

It means,

[tex]\dfrac{2}{x}=\dfrac{12}{18}[/tex]

[tex]2\times 18=12\times x[/tex]

[tex]36=12x[/tex]

Divide both sides by 12.

[tex]\dfrac{36}{12}=\dfrac{12x}{12}[/tex]

[tex]3=x[/tex]

Therefore, the value of x is 3.

Answer:

the answer is 6

Step-by-step explanation:

Answer:

y=tan(x/10)

Step-by-step explanation:

actually period of tanx is Pi

so y=tan(x/10) is the answer

because you plug in x=10pi

you will get inside the bracelet is pi

Answer:

The graph of line x = -4  is also attached below.

The graph indicates that no matter what the value of y is, the x-value remains the same.  Hence, the line is vertical with undefined slope,

Step-by-step explanation:

Given the line

x=−4

The given line x=-4 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-4 is undefined.

As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.

The graph of the line x = -4  is also attached below.

The graph indicates that no matter what the value of y is, the x-value remains the same.  Hence, the line is vertical with undefined slope,

Answer:

Option 1 is correct i.e.

[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2=\frac{2^6.1^2}{5^2}=\frac{64}{25}[/tex]

Step-by-step explanation:

We need to simplify the expression: [tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2[/tex]

We know that: [tex](a^m)^n= a^{m*n}[/tex] and [tex]a^0=1[/tex]

We would use these exponent laws to solve our question.

First we will apply [tex]a^0=1[/tex]

[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2\\=(\frac{2^3\:\textbf{.}\:1}{5})^2\\[/tex]

Now, we will apply [tex](a^m)^n= a^{m*n}[/tex]

[tex]=\frac{(2^3)^2\:\textbf{.}\:1^2}{5^2}\\=\frac{2^6\:\textbf{.}\:1}{5^2}\\=\frac{64}{25}[/tex]

So, the result is: [tex]\frac{64}{25}[/tex]

Therefore, Option 1 is correct i.e.

[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2=\frac{2^6.1^2}{5^2}=\frac{64}{25}[/tex]

Answer:

y ≈ 18.3

Step-by-step explanation:

Using the sine ratio in the right triangle

sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{y}[/tex] ( multiply both sides by y )

y × sin41° = 12 ( divide both sides by sin41° )

y = [tex]\frac{12}{sin41}[/tex] ≈ 18.3 ( to 1 dec. place )

Answer:2430

Step-by-step explanation:

Answer:

Ancient Egypt included two regions, a southern region and a northern region. The southern region was called Upper Egypt. It was so named because it was located upriver in relation to the Nile's flow. Lower Egypt, the northern region, was located downriver.

Answer:

53,337

Step-by-step explanation:

Answer:

53337

Step-by-step explanation:

There ya go.

Given :

There are currently 260 people in archery clubs across the city, and this number is increasing by 11% per year.

To Find :

An equation that can be used to find the number of people, y, in archery clubs across the city after 8 years.

Solution :

Increase in people after 1 years :

[tex]P = 260 + 260\times 0.11\\\\P = 260( 1 + 0.11)\\\\P = 260\times 1.11[/tex]

After 2 years :

[tex]P = 260\times 1.11 + 260\times 1.11\times 0.11\\\\P = 260\times 1.11 ( 1 + 0.11)\\\\P = 260\times 1.11^2[/tex]

Therefore, after 8 years the expression of population is :

[tex]P = 260\times 1.11^8[/tex]

Hence, this is the required solution.

Answer:

20.8333%

Step-by-step explanation:

It means There was shortage of food, so it ended up with 19 people.

Original Value = 24 people New Value = 19 people

There is a Percentage decrease

%decrease = Original Value - New Value / Original Value × 100%

%decrease = 5/24 × 100%

%decrease = 20.8333 %

So, more 20.8333% would be needed so that 24 people can get the food  .

Answer: 26

Step-by-step explanation:

(24-19)/19 * 100 = 26.3157894736842

But it said to round to the nearest percent I believe since I got the same question, so 31 isn't above 50 so 26 is just 26 since 31 not above 50, so the answer is just 26

Hope this helps, sorry if im wrong but for me it was right!

Answer:

The property of equality that justifies going from the first statement to the second statement  is;

Subtraction property of equality

Step-by-step explanation:

The given equation is presented here as follows;

AB + BC = 42

AB = 42 - BC

The above equation can be simplified as follows;

AB + BC = 42

AB + BC - BC = 42 - BC

(+ BC - BC = 0)

Therefore, we have;

AB + BC - BC = AB + 0 = AB = 42 - BC

AB = 42 - BC  which is the subtraction property of equality

For the subtraction property of equality, when we subtract a value from one side of the equation, we must subtract the same value from the side of the equation as follows

Given that the letters a, b, and c represent any numbers

When we have;

a = b

Then we also must have;

a - c = b - c

Answer:

The Circumference of the circle = C = 24π mm

Hence, option C is true.

Step-by-step explanation:

Given

Radius  r = 12mm

To Determine

Circumference of circle C = ?

Using the formula to determine the Circumference of the circle

C = 2πr

substituting r = 12mm in the equation

C = 2π(12)

C = 24π mm

Therefore, the Circumference of the circle = C = 24π mm

Hence, option C is true.

Answer:

d.y=x/3+4

Step-by-step explanation:

we have

slope=(y-b)÷(x-a)

1/3=(y-2)÷(x--6)

(x+6)=3(y-2)

x+6=3y-6

x+6+6=3y

(x+12)÷3=y

y=x/3+4
