Expand 5(2x-y)

Answer:

Yes.

Step-by-step explanation:

The sum of the interior angles of triangles always add up to 180 degrees. The third angle of the top triangle would be 27. The third angle of the bottom triangle is 63.

Triangles are similar if the angles are the same. Therefore the 2 triangles are similar.

Hope that this helps!

Answer:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.\

Answer:

the fiorst plan

Step-by-step explanation:

Answer:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}[/tex]

let's figure out [tex]A_{\rm square}[/tex]:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times b \times h[/tex]

substitute h and b

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times 4 \times 4[/tex]

reduce fraction:

[tex] \displaystyle A _{ \rm triangle} = 2 \times 4[/tex]

simplify multiplication:

[tex] \displaystyle A _{ \rm triangle} = 8[/tex]

likewise square

[tex] \displaystyle A _{ \rm squre} = {s}^{2} [/tex]

substitute s:

[tex] \displaystyle A _{ \rm squre} = {7}^{2} [/tex]

simplify square

[tex] \displaystyle A _{ \rm squre} = 49[/tex]

hence,

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =49- 8[/tex]

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

to figure out perimeter

let's figure out hypotenuse first

[tex] \displaystyle h = \sqrt{ {4}^{2} + {4}^{2} } [/tex]

[tex] \displaystyle h = \sqrt{ 16 + 16} [/tex]

[tex] \displaystyle h = 4 \sqrt{2} [/tex]

therefore,

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2} + 7 + 7[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2} + 14[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Answer:

a) Log ( 2 ) = 4t Log ( 83/80 )

b) 4.7 years

Step-by-step explanation:

Attached below is the detailed solution

a) exponential statement in log form for an investment at 15% quarterly

Log ( 2 ) = 4t Log ( 83/80 )

n = 4 ,  r = 15

b) using change to base  to find double time in yr

Double time in yr

t = Log ( 2 ) / 4log ( 83/80 )

= 4.7 years

For the first inequality, x > -1

For the second inequality, x < -1

Step-by-step explanation:

5x - 29 > -34

add 29 to both sides

5x > -5

divide both sides by 5

x > -1

-----------------------------------------------------

2x + 31 < 29

subtract 31 from both sides

2x < -2

divide both sides by 2

x < -1

Answer:

a

Step-by-step explanation:

Answer:

x = 36

Step-by-step explanation:

Given

3(2x - 5) - 2x = 3(x + 7) ← distribute parenthesis on both sides

6x - 15 - 2x = 3x + 21

4x - 15 = 3x + 21 ( subtract 3x from both sides )

x - 15 = 21 ( add 15 to both sides )

x = 36

Answer:

Step-by-step explanation:

Hello : let A(4,5) B(0,-12)

the slope is : (YB - YA)/(XB -XA)

(-12-5)/(0-4) = 17/4

an equation is : y=ax+b a is a slope

y = (17/4)x +b

the line through point B(0,-12) : -12 = (17/4)(0)+b

b =-12

the equation is : y =(17/4)x-12
