Step-by-step explanation:

1.

(2x-11)° = 105° (vertical angles)

2x - 11 = 105

2x = 105 + 11

2x = 116

x = 116/2

x = 58

m\angle BEC = (2x - 11)\degree \\m\angle BEC = (2\times 58-11)\degree \\m\angle BEC = (116-11)\degree \\\huge m\angle BEC = 105\degree \\m\angle AEB =180\degree - 105\degree \\(straight \: line \: \angle 's) \\\huge m\angle AEB =75\degree \\m\angle CED=m\angle AEB = 75\degree\\ (vertical \:\angle' s) \\

2.

(6x + 19)\degree + x \degree = 180\degree \\(straight \: line \: \angle 's) \\(7x + 19) \degree = 180\degree\\7x + 19 = 180\\7x = 180 - 19\\7x = 161\degree \\x =\frac{161}{7}\\x = 23\\m\angle AEB=(6x + 19)\degree \\m\angle AEB=(6\times 23+ 19)\degree \\m\angle AEB=(138+ 19)\degree \\\huge m\angle AEB=157\degree \\m\angle CED=m\angle AEB = 157\degree\\ (vertical \:\angle' s) \\m\angle BEC = x\degree \\\huge m\angle BEC = 23\degree \\m\angle AED =m\angle BEC=23\degree \\(vertical \:\angle' s) \\

Two quantities are related, as shown in the table:
vampirchik [111]
Y=mx+b, m=delta y / delta x...from the table we can see that m=3/2 so our equation becomes:

y=3x/2 + b, using any point, I'll use (2,2) we can now solve for b, or the y-intercept...

2=3(2)/2 +b

2=3+b, b=-1  our line is thus:

y=1.5x-1

Marcy played the piano for 45 mins she stopped playing at 4:15 pm at what time did she start playing the piano
elixir [45]
We know that
1 hour----------> 60 min

step 1
convert hours to minutes
<span>4:15---------> 4 hour +15 minutes------> 4*60+15-----> 255 minutes

step 2
</span><span>subtract 45 minutes
</span>255-45--------> 210 minutes

step 3
convert to hour
1 hour----------> 60 min
x-----------------> 210 min
X=210/60---------> X=3.5 hour
3.5 hour
that means
3 hour+0.5 hour
and 0.5 hour is-----------> 0.5*60----> 30 minutes
therefore
3.5 hour-------> 3 hour +30 minutes-------->3:30 pm

the answer is
3:30 pm

What is the volume of this pyramid? 945 cm³ 1260 cm³ 1890 cm³ 2520 cm³ A pyramid with a right triangular base. The right triangu
notsponge [240]

Answer:

The volume of the pyramid is 1,260\ cm^{3}

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

V=\frac{1}{3}BH

where

B is the area of the triangular base

H is the height of the pyramid

step 1

Find the area of the base B

B=\frac{1}{2}bh

we have

b=14\ cm

h=18\ cm

substitute

B=\frac{1}{2}(14)(18)=126\ cm^{2}

step 2

Find the volume

we have

B=126\ cm^{2}

H=30\ cm

substitute

V=\frac{1}{3}BH

V=\frac{1}{3}(126)(30)=1,260\ cm^{3}

Evaluate each expression:<br> I-3|=
mote1985 [20]

The value of the modulus function |-3| is 3.

<h3>What is the value of modulus?</h3>

'Modulus' exists a Latin word, which signifies 'measure'. Absolute value is commonly referred to as numeric value or magnitude. The absolute value designates only the numeric value and does not contain the sign of the numeric value. The modulus of any vector quantity exists ever taken as positive and exists in its absolute value.

The absolute value (or modulus) | x | of a real number x stands as the non-negative value of x without regard to its sign.

For example, the absolute value of 5 stands at 5, and the absolute value of −5 exists also at 5. The absolute value of a number may be considered as its distance from zero along a real number line.

Therefore, the value of the modulus function |-3| is 3.

To learn more about the value of modulus refer to:
