26. Answer 44

6x + 11 = 10x - 9

subtract 11 and 10 from both sides to get
-4x = -20 then divide that by negative 4 whicg will get you x=5 then plug in
6(5)+11=44

27. Answer 18

9x-4=158 since bisect means cut into 2 equal pieces so abd and dbc equal 79, add 4 to get 162 then divide by 9 to get x=18

29. Answer 28

2h+6+h=90

(____)
this part represents G
complementary angles are two angles that add up to 90, so subtract 6 from 90 and add the variables to get 3h=84 then divide by 3

H = 28 to check you can plug 28 into the equation

ECD=90 ECD=x+5+3x-7=4x-2, 4x-2=90, 4x=92, 4x/4=92/4, x=23
a) 23
ECH=x+5, 23+5=28, ECH=28
b)28
HCD=3x-7, 3(23)-7, 69-7=62 HCD=62
c)62
GCF & ECH are vertical angles, GCF=28
d) 28
ECF=180, 180-28(GCF)=152, ECF=152
e) 152
DCF=90, 90+28(GCF)=118
f) 118

Given the below sequence:
kvasek [131]

Answer:

a) The next three terms are -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence

C) The difference of second term and first term is -2 in given sequence so the given sequence is an arithmetic sequence.

d) The 27 th term is -53

Step-by-step explanation:

a)  the given sequence is arithmetic sequence

the difference of second term and first term is -2

given sequence is -1,-3,-5,-7.....

the nth term in arithmetic sequence

t_{n} = a+(n-1)d

First term is a = -1 and difference is d = -2

finding fifth term is

t_{5} = -1 +(5-1)(-2)

t_{5} = -1-8 =-9

finding sixth term is

t_{6} = -1 +(6-1)(-2)

t_{6} = -1-10 =-11

finding seventh term is

t_{7} = -1 + (7-1)(-2)

t_{7} = -1 -12 =-13

The next three terms are  -9,-11,-13

The given sequence is -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence.

C) because the difference of second term and first term is -2 so the given sequence is arithmetic sequence.

d) by using nth term formula in arithmetic sequence

t_{n} = a+(n-1)d

a= -1 and d =-2

<u>find 27 t h term :-</u>

<u></u>t_{27} = -1 + (27-1)(-2) = -1-52=-53<u></u>

B) The number of volume of a cylinder is half of its number of the total surface area.
faust18 [17]

Answer:

V=179.6cm^3

Step-by-step explanation:

the volume of a cylinder is given by:

V=\pi r^2h

where r is the radius and h is the height.

and the surface area:

SA=2\pi r^2+2\pi rh

the first term is the area of the circles and the second term is the area of the body.

since "The number of volume of a cylinder is half of its number of the total surface area." we will have that:

V=\frac{1}{2}SA

substitutig the equivalent expressions on each side:

\pi r^2 h = \frac{1}{2} (2\pi r^2+2\pi r h)

and we simplify and solve for the height (since is the value we don't know of the cylinder):

\pi r^2 h = \pi r^2+\pi r h\\\pi r^2h-\pi rh=\pi r^2\\h(\pi r^2-\pi r)=\pi r^2\\h=\pi r^2/(\pi r^2-\pi r)

we substitute the value of the radius r=7cm, and we get:

h=\pi (7cm)^2/(\pi (7cm)^2-\pi (7cm))\\h=153.938/(153.938-21.991)\\h=153.938/131.947\\h=1.1666cm

thus the volume is:

V=\pi r^2h

V=\pi (7cm)^2(1.1666cm)\\V=179.6cm^3
