Write 81% as a decimal.

Answer:

87°

Step-by-step explanation:

if an angle is complementary that means that equals 90°.

and we know one part of the angles, so then we take 90° - 3° and we get 87°.

Answer:

The measure of its complementary angle is 87°

Step-by-step explanation:

We know this because the sum of two complementary angles is always equal to 90°, so:

90 - 3 = 87

Therefore, your final answer will be 87°

Answer:

a=2

Step-by-step explanation:

you take 20 and subtract it from both sides and then 22-20 is 2 so a equals to 2.

Answer:

x=1   and  y=-2

Step-by-step explanation:

5-2i-7=-2-2i

x-(3-yi)=x-3+yi

we write this equation   -2 - 2i = (x-3)  +yi

so -2=x-3                  and       -2i=yi    

    +3      +3                               :i    :i

    1=x                                         -2= y

so x=1      and   y= -2

Answer:

X equal to 8

Step-by-step explanation:

Three times eleven

Thirty three minus one

Thirty two divide by four

Answer: x=8

Step-by-step explanation:

Given

[tex]\frac{4x+1}{3} =11[/tex]

Multiply 3 on both sides (multiplication property of equality)

[tex]\frac{4x+1}{3} *3=11*3[/tex]

[tex]4x+1=33[/tex]

Subtract 3 on both sides (subtraction property of equality)

[tex]4x+1-1=33-1[/tex]

[tex]4x=32[/tex]

Divide 4 on both sides (division property of equality)

[tex]4/4 x= 32/4[/tex]

[tex]x=8[/tex]

Step-by-step explanation:

For y = x^3 - 4 when x = 0, y = -4.

For y = x^2 + 3 when x = 0, y = 3.

Looking at the graph, the y-intercept of the function is below 0. Hence the bottom part is from x^3 - 4 and the top is from x^2 + 3.

The bottom part has a dark circle, which means when x = 1 it belongs to x^3 - 4.

Hence the answer is D.

Answer:

when you translate you move the "x" term.

Step-by-step explanation:

Answer:

decimal : 1

fraction :  1

Step-by-step explanation:

Percentage is always out of 100

100%

to convert from percentage to a fraction, you just put 100 and the bottom of that number;

[tex]\frac{100}{100}[/tex] ; this is equal to 1

to convert percentages to a decimal, we divide by 100;

100 ÷ 100 = 1

Answer:

A. vertex B

B. Side BC and BD

C. Angle EBD

Step-by-step explanation:

An angle is an undefined term in plane geometry.

Vertex of [tex]\angle 4[/tex]

The vertex of an angle is the point where the rays that form the angle meet.

From the diagram, rays BE and BA meet at point B to form [tex]\angle 4[/tex].

Hence, the name of the vertex is B

Sides of [tex]\angle 1[/tex]

The sides of an angle are the rays or sides that form the angle

[tex]\angle 1[/tex] is formed by rays BC and BD

Hence, the sides are BC and BD

Another name for [tex]\angle 5[/tex]

An angle can be named by combining the sides and the vertex.

The sides of [tex]\angle 5[/tex] are DB and BE, while the vertex is B

This means that rays DB and BE meet at point B

Hence, another name is [tex]\angle DBE[/tex]

Classify the angles

Angles are classified based on the measure

[tex]\angle FBC[/tex] is a right angle, because [tex]\angle FBC = 90^o[/tex]

[tex]\angle EBF[/tex] is an obtuse angle because [tex]\angle EBF[/tex] is greater than [tex]90^o[/tex] but less than [tex]180^o[/tex]

[tex]\angle ABC[/tex] is a straight angle, because [tex]\angle ABC= 180^o[/tex]

Angle bisector

The line or ray that divides an angle into equal halves is an angle bisector.

Ray BE is an angle bisector, because it divides [tex]\angle DBA[/tex] into two equal halves.

Find [tex]\angle EBC[/tex]

We have:

[tex]\angle EBD = 36[/tex]

[tex]\angle DBC = 108[/tex]

[tex]\angle EBC[/tex] is calculated using:

[tex]\angle EBC = \angle EBD +\angle DBC[/tex]

[tex]\angle EBC = 108+36[/tex]

[tex]\angle EBC = 144[/tex]

Find [tex]\angle ABE[/tex]

We have:

[tex]\angle EBF = 117[/tex]

[tex]\angle DBC = 108[/tex]

[tex]\angle ABE[/tex] is calculated using:

[tex]\angle EBF = \angle ABE +\angle EBD + \angle ABF[/tex]

Where

[tex]\angle ABF = 90[/tex]

[tex]\angle ABE = \angle EBD[/tex]

So, we have:

[tex]117 = \angle ABE +\angle ABE + \angle 90[/tex]

[tex]117 = 2\angle ABE + 90[/tex]

Collect like terms

[tex]2\angle ABE =117 - 90[/tex]

[tex]2\angle ABE =27[/tex]

Divide both sides by 2

[tex]\angle ABE =13.5[/tex]

Answer:

d−14=34 shows that when we add sold drawing we get the total drawings

Step-by-step explanation:

We have been given that Rosa brought d drawings to an art show.

After selling 14 of them, she had 34 left.

We have to form a equation such that when we add 14 in 34 we get the total of drawings.

d-14=34d−14=34 (1)

Equation (1) shows that when we add sold drawing we get the total drawings

Answer:

d-14=34. 34+14=48. 48-14=34 which is our total

The three numbers between 0.63 and 0.64 will be 0.6325, 0.6350, and 0.6375.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The number between 0.63 and 0.64 is calculated as,

⇒ (0.63 + 0.64) / 2

⇒ 0.635

The number between 0.63 and 0.635 is calculated as,

⇒ (0.63 + 0.635) / 2

⇒ 0.6325

The number between 0.635 and 0.64 is calculated as,

⇒ (0.635 + 0.64) / 2

⇒ 0.6375
