4. -15

Answers

Answer:

2

Step-by-step explanation:

just put -3 to x

9-7=2

X^2 + 2x - 1 when x = -3
= -3^2 + 2(-3) -1
= 9 - 6 - 1
= 3 - 1
= 2
So the answer to this question is 2.

Lines and Angles

There are properties of lines and angles that will help us to find the required values.

The vertex at the bottom left side of the quadrilateral has two angles that were formed when two lines crossed. Those are called linear angles, and they always add up to 180°.

This means that z is the angle needed to complete 180°, that is:

z = 180° - 101° = 79°

Now the quadrilateral must have the sum of its internal angles equal to 360°. We have three of them that sum: 100°+88°+79°=267°.

This means y is the angle needed to complete 360°, or:

y = 360° - 267° = 93°

Answer: y=93°, z=79°

Can somebody show me how to do this?

In quadrilateral ABCD m < A= 90°
m 2 C = 50° and m < B = m D.
Find the degree measure of < B.

Answers

Answer:

m∠B = 170°

Step-by-step explanation:

Sum of all angles in quadrilateral is 360°:

m∠A + m∠B + m∠C + m∠D = 360°

m∠B = 360° - m∠A - m∠C - m∠D

m∠A = 90°

m∠B = m∠D= 50°

m∠B =  360° - 90° - 50° - 50° = 170°

x = 4.99°

Step-by-step explanation:

Reference angle = x

Opposite side to x = 20 cm

Hypotenuse = 230 cm

Applying trigonometric ratio formula, we would have the following equation:

[tex] sin(x) = \frac{Opp}{Hyp} [/tex]

Plug in the values

[tex] sin(x) = \frac{20}{230} [/tex]

[tex] x = sin^{-1}(\frac{20}{230}) [/tex]

x = 4.99° (approximated to nearest hundredth)

Answers

Answer:

  30°

Step-by-step explanation:

The angle a line makes with the x-axis is arctan(slope). Here, that is ...

  angle with x-axis = arctan(√3) = 60°

So, the angle made with the y-axis is the complement of this:

  angle with y-axis = 90° -60° = 30°

We conclude that

[tex]4\frac{2}{3}[/tex]    >   [tex]\sqrt{21}[/tex]

Step-by-step explanation:

Given

[tex]\sqrt{21}[/tex][tex]4\frac{2}{3}[/tex]

as

[tex]\:\sqrt{21}=4.58[/tex]

and

[tex]4\frac{2}{3}[/tex]

Convert mixed numbers to improper fraction:

[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]

so

[tex]4\frac{2}{3}=\frac{4\cdot 3+2}{3}=\frac{14}{3}=4.67[/tex]

Thus,

[tex]\:\sqrt{21}=4.58[/tex]

[tex]4\frac{2}{3}=4.67[/tex]

as

4.67      >       4.58

so

[tex]4\frac{2}{3}[/tex]         >        [tex]\sqrt{21}[/tex]

Hence, we conclude that

[tex]4\frac{2}{3}[/tex]    >   [tex]\sqrt{21}[/tex]

How is 75% of 60 minutes 45?

Answers

Answer:

It just is see explanation

Step-by-step explanation:

75% is equal to 0.75, or 3/4. If you multiply the full 60 minutes to 3/4, then your product is 45 minutes. That's how 75% of 60 minutes is 45 minutes.

Answer: 75% of a number is the same thing as 3/4 of the number.

so for example, divide 100 by 4. you get 25 right?

right, so multiply 25 by 3 and you get 75. That's what 3/4 of something is.

now divide 60 by 4. you get 15 right?

right, so multiply 15 by 3, and you get 45 :)))

that's why 75% of 60 is 45.

i hope this helps!!

BTW when you get a question with percentages, you can flip them! In this case it doesn't really help to do so, but for example if you had a question asking:
