Step-by-step explanation:

13² = 7² + x²

169 = 49 + x

x² = 169 - 49

x² = 120

x = [tex]\sqrt{120}[/tex] (do this stpd calculus)

x = 2[tex]\sqrt{30}[/tex]

________

[tex] \: [/tex]

x² = 13² - 7²

x² = 169 - 149

x² = 120

x = √120

x ≈ 2√30m

Answer:

s/5=b

Step-by-step explanation:

The required expression is n/5 = b

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given:

We have the variable b to represent the unknown quantity.

The expression,

the number of soda bottles split 5 ways.

That means,

Let n be the number of soda bottles.

So,

using division operation,

n / 5 = b

Therefore, the expression is n/5 = b.

-3.2

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

I've attached a picture, and I hope it's clear and understandable.

Answer: k=9

Step-by-step explanation:

Parallel lines have the same slope. y=mx+b, where m is the slope. The reference line, y = 6x-5 has a slope of 6. The new line must therefore also have a slope of 6. The slope is the Rise/Run, the change in y for a change in x.

The two points on the new line are (10,2k) and (13,4k). Rise over run for this new line is (4k-2k)/(13-10) or 2k/3. This must be equal to 6,

2k/3 = 6

2k = 18

k = 9

Answer:

136.8

Step-by-step explanation:

As per DMAS rule, we can divide first or multiply first. I would choose divide first. Then:

4.56 x 3.6/0.12

= 4.56 x 30.

Since I divided first, the next step is to multiply.

4.56 x 30

= 136.8

Since there is no addition or subtraction happening next, the process ends here and the answer is 136.8.

Kind requests:

Please give me brainliest if this was helpful.

The expression value  [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10².

To evaluate the expression [tex]4.56 \times \frac{ 3.6}{0.12}.[/tex]

Find the multiplication of the numerator with 4.56 and then divide it by 0.12.

Perform the multiplication first:

4.56×3.6 = 16.416

Now we divide the result by 0.12:

[tex]\frac{16.416}{0.12} = 136.8[/tex]

To express the answer in standard form, we rewrite it as a number multiplied by a power of 10.

In this case, we move the decimal point two places to the right to obtain a whole number:

136.8=1.368×10²

Therefore, the answer to the expression  [tex]4.56 \times \frac{ 3.6}{0.12}[/tex] in standard form is 136.8=1.368×10²

Answer:

3 inches

Step-by-step explanation: An equilateral triangle means all 3 sides are the same length.

A square also have the same length for all 4 sides.

So each side of the square is 6cm, to find the perimeter you do 6*4=24.

then divide the square's perimeter by 3 since triangle have 3 sides. 24/3=8

so each side of the triangle will be 8cm

slope intercept form y=mx+b

you just need to move the letters and numbers around to match this.

-4x-3y=-18

add 4x to both sides of the equal sign

-3y =4x-18

divide by negative 3 on both sides

y = -4/3x + 6

21. -2x+3y=21

add 2x to both sides

3y = 2x + 21

divide by 3 on both sides

y = 2/3x +7

The amount that the man have in his bank at the second year is $100,352.

Using this formula

A=P(1+R÷100)^n

Where:

A=Amount

P=Principal=$80,000

R=Rate=12%

n=Number of years=2 years

Let plug in the formula

A=$80,000(1+12÷100)^2

A=$80,000(1+0.12)^2

A=$80,000(1.12)^2

A=$80,000(1.2544)

A=$100,352
