Step-by-step explanation:

27*23

Although. Don't. Trust. it

Answer:

621

Step-by-step explanation:

23 times 27 = answer

0.5 => 5/10 => 1/2

12.3 => 123/10

0.07 => 7/100

0.625 => 625/1000 => 25/40 => 5/8

Answer:

see below

Step-by-step explanation:

0.5, 5/10 = 1/2

12.3 = 12 3/10

0.07 = 07/100

0.625=625/1000 =5/8

Answer:

y = x2 + x - 20 factors into

y = (x +5) * (x -4)

Step-by-step explanation:

Answer:

y = (x + 5)(x - 4)

Step-by-step explanation:

Given

y = x² + x - 20

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (+ 1)

The factors are + 5 and - 4, since

5 × - 4 = - 20 and 5 - 4 = + 1, thus

x² + x - 20 = (x + 5)(x - 4)

Answer:

90.00

Step-by-step explanation:

because all they did was add a couple of hundred that would not boost the 55.35 all the way to the thousands so A is not right It's not B because 55.35 is more than 34.04 so it's not B it's not D because 44,444.44 is just way too high it's even higher than option A.

Answer:

A

Step-by-step explanation:

The formula for circumference is C = 2[tex]\pi[/tex]r. When plugging in these values, 2 x 3.14 x 4.5 is equal to 28.26.

Circumference of her garden is 28.26 m. So, Option 'A' is the correct answer to the following question.

What information do we have?

Radius of circular garden = 4.5 m

Circumference of her garden = circumference of circle

So,

Circumference of her garden = 2πr

Circumference of her garden = 2(3.14)(4.5)

Circumference of her garden = 28.26 m

Answer:

50°

Step-by-step explanation:

In the figure attached, the plot of the problem is shown.

Assuming that segments DE and CF are parallel then the following angles are congruent:

∠DEG ≅ ∠CFG

∠CGF ≅ ∠DGE

∠GCF ≅ ∠GDE

As a consequence, ∠DEG = 50°

Step-by-step explanation:

I think you either multiply I’m really not sure but that’s my opinion on how to solve this

Solving for each equation:

A: True.

[tex]\frac{n}{2} +3 *4 = \frac{n}{2}+12\\\\\frac{n}{2} + 12 = \frac{n}{2} + 12[/tex]

B: False.

[tex]\frac{1}{3}z+\frac{2}{3}z * 9 = 9z\\\\\frac{1}{3} z+6z = 9z[/tex]

C: True, given that y = 1

[tex]-8y +4.3y + 3.7 = 0\\\\-3.7y = -3.7[/tex]

D: True, given that b = 6.66667

[tex]12-1.8b+1.8b=1.8b\\12 = 1.8b[/tex]

E: True.

[tex]\frac{m}{8} + 7(\frac{m}{8} ) =m\\\\\frac{m}{8} + (\frac{7m}{8} )= m\\\\\\\frac{8m}{8} = m\\[/tex]

Answer:

Inverse.

Step-by-step explanation:

Inverse trigonometric functions.

e. g. tan-1 x means 'the angle whose tangent is x'.

They are also called arcsin, arccos and arctan.

The equation that represents the relationship between x and y shown in the table is; y= 2x-3

An equation is an expression that shows the relationship between two or more numbers and variables.  the equations that can be solved to get a unique solution. the power of the equation must be in one degree.

First we need to find the slope we will use rise over run to get 2.

The correct equation will replace x with any of the x values in the chart and if we get the same y values as the chart then that equation is correct.

y= 2x-3

If x = 2 and y = 1

Then

y= 2x-3

1 = 2(2)-3

1= 1

Therefore, The equation that represents the relationship between x and y shown in the table is; y= 2x-3
