What is 23/100 + 7/10

whenever we run a perpendicular line to a base from a right-angle in a right-triangle, like in this case, we end up with 3 similar triangles, a Small one, a Medium and a containing Large one, thus Check the picture below.

Answer:

y= -2x+1

Step-by-step explanation:

y=mx+b

-1= -2(1)+b

-1= -2+b

b= 1

y= -2x+1

Necessary Formulas:

Area of a Square = base x height OR length^2

---All sides of a square are the same length!

Perimeter of a Square = 4 x length

Steps to Solve:

Area of the square = length^2

49 = length^2

length = 7

Perimeter of the square = 4 x length

Perimeter = 4 x 7

Perimeter = 28

Answer:

The perimeter of the square is 28 meters.

Hope this helps!

Answer: D. 5 - x^4

Step-by-step explanation: We can see that the blue function is translated three units up, and inverted, so its leading coefficient is negative. The blue function can be rewritten as -x^4 + 3 to reflect these transformations. The only difference between the blue and the red function is that the red is two units higher, or five units total from the origin. Since they are the same shape, it will have a -x^4 in the formula, but since it is translated five units up its formula will be -x^4 + 5, which is also equal to 5 - x^4.

Answer:

1/2 of farm land left.

Step-by-step explanation:

  Ok so we know that Chef Ollie has a community garden. And that she uses [tex]\frac{2}{6}[/tex] of the farmland to grow beets. The denominator 6 lets you know immediately that the land is divided into equal 6 pieces. We also know that Chef Ollie uses another [tex]\frac{1}{6}[/tex] of the farmland to grow kale.

  Because the we need to find out how much land Chef Ollie has left, we need to subtract the amount she used from the whole. Before we can do that we must add up the total amount of used land, and since the denominators are the same we can directly add and subtract with having to change the denominator.

Step 1: Write down important numbers.

[tex]\frac{2}{6}[/tex], [tex]\frac{1}{6}[/tex],

Step 2: Add those numbers together.

[tex]\frac{2}{6} + \frac{1}{6} = \frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex]

Step 3: Write an expression/equation.

[tex]\frac{6}{6} - \frac{3}{6} \\or\\1 - \frac{1}{2}[/tex]

Step 4: Solve

=    [tex]\frac{3}{6}\\or\\\frac{1}{2}[/tex]

(can be written both ways)

  And you get your answer: After Chef Ollie has used [tex]\frac{2}{6}[/tex] to grow beets and [tex]\frac{1}{6}[/tex] to grow kale, she has [tex]\frac{1}{2}[/tex] of her farmland left untouched.

  To represent this you could draw a circle divided in 6 pieces and shade 3 of them, or simply draw a circle and shade half. As well as drawing a rectangle and dividing it into 6 pieces, shading 3, or draw a rectangle, and shade half.

[tex]tan(x)=2.5\implies \measuredangle x=tan^{-1}(2.5)\implies \measuredangle x\approx \begin{cases} \stackrel{I~Quadrant}{68.2^o}\\\\ \stackrel{III~Quadrant}{248.2^o} \end{cases}[/tex]

Make sure your calculator is in Degree mode, Check the picture below on the left side.

well, the tangent recall is sine/cosine, or namely y/x, for that fraction if either of them is negative, the whole fraction is negative, if both are either positive or negative, the fraction is positive.

given such, on the 1st quadrant and 3rd quadrant that fraction y/x is positive because on the 1st quadrant both are positive and on the 3rd quadrant both are negative, yielding the fraction, namely tangent, positive.

[tex]cos(x)=-0.7\implies \measuredangle x=cos^{-1}(-0.7)\implies \measuredangle x\approx \begin{cases} \stackrel{II~Quadrant}{134.43^o}\\\\ \stackrel{III~Quadrant}{225.57^o} \end{cases}[/tex]

now, check the picture below on the right side, cosine or namely "x", is negative on the 2nd and 3rd quadrants only, the first angle you'd get from your calculator will be 134.43°, now, this one is on the 2nd quadrant, so it has a margin from 180° of 180 - 134.43 = 45.57, that means the angle of reference is 45.57° in red in the picture.

to get the 2nd angle on the 3rd quadrant, we add to 180° the reference angle, so 180 + 45.57 = 225.57°.

Probabilities are used to determine the chances of events

The area of region X is:

[tex]A = \pi r^2[/tex]

So, we have:

[tex]X = 3.14 * 4^2[/tex]

[tex]X = 50.24[/tex]

The area of the dart is:

[tex]A = Length * Width[/tex]

[tex]A = 24 * 24[/tex]

[tex]A = 576[/tex]

The probability of landing in region X is then calculated as:

[tex]P(X) = 50.24/576[/tex]

[tex]P(X) = 0.087[/tex]

The area of region Y is:

[tex]A = \pi R^2 - \pi r^2[/tex]

So, we have:

[tex]Y = 3.14 * 6^2 -3.14 *4^2[/tex]

[tex]Y = 62.8[/tex]

The probability of landing in region Y is then calculated as:

[tex]P(Y) =62.8/576[/tex]

[tex]P(Y) =0.109[/tex]

The area of region Z is:

[tex]A = \pi R^2 - \pi r^2[/tex]

So, we have:

[tex]Z = 3.14 * 8^2 -3.14 *6^2[/tex]

[tex]Z = 87.92[/tex]

The probability of landing in region Z is then calculated as:

[tex]P(Z) = 87.92/576[/tex]

[tex]P(Z) = 0.153[/tex]

Hence, the probability of landing in region Z is 0.153

Answer:

s = 4

Step-by-step explanation:

3(s + 8) = 36

Simplify the distributive property:

⇒ 3s + 24 = 36

Subtract 24 both sides:

⇒ 3s = 36 - 24

⇒ 3s = 12

Divide 3 both sides:

⇒ 3s/3 = 12/3

⇒ s = 4
