Five times a number is the same as 30 more than 8 times the number. Find the number. If n is "the number," which equation could be used to solve for the number? 3n = 30 5n + 8n = 30 5n = 8n + 30

Answers

Answer 1

Answer:

C. 5n = 8n + 30

Step-by-step explanation:

5 times a number = 5n

30 more than 8 times a number = 30 + 8n

If those expressions are equal, then:

5n = 8n + 30

so since the equation is right by 100 it equals 100 sooo
6x + 52 = 100
now we solve
6x = 48
x = 8
and then for zz it’s 360 - 200
which is 160
divide by 2 so
80
SOOOO
x = 8
z = 80
sorry the explaining sucks ;-;

Answer:

X=8

z=80

Step-by-step explanation:

Okay to find X you gotta find the other angle.

The other angle is 100 which is also vertical To (6x+52)

Vertical angles are equal or congruent so you cna make an eqaution to equal it

6x+52=100

Solve it like a normal equation

x=8

To find Z you gotta realize that 4 angles equal 360 degrees.

We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z

Now If you add em all up you should get 360

2z+100+100=360

2z+200=360

Solve from here

z=80

Question 1 of 10
Which of the following correctly describes the end behavior of the

A. The left end goes up and the right end goes down.
B. Both ends
go
down.
C. Both ends go up.
D. The left end goes down and the right end goes up.

Answers

Answer:

Ok, so it seems

erm

ok, even and odd

it is an odd one because the power is odd (3rd degree)

so then the ends go in different directions

and since leading coefient (5 in the 5x^3) is positive, it goes from bottom left to top right

so

A is false

B is false

C and D are true

answer is C and D

find the total surface area of the following cone. leave your answer in terms of pi.

Answers

Answer:

90pi

Step-by-step explanation:

SA = pi r l +B

we know the radius is 5

We need to find the slant height using the Pythagorean theorem

a^2+b^2 = c^2

5^2+12^2 = l^2

25+144= l^2

169 = l^2

Taking the square root of each side

sqrt(169) = sqrt(l^2)

13 = l

B is the area of the base

B = pi r^2 = pi (5)^2 = 25 pi

SA = pi r l +B  = pi (5)*13 + 25pi

                       =65pi +25pi = 90pi

Answer:

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 43

Given that the mean of the sample = 47

Given that the standard deviation of the Population = 25

Given that the sample size 'n' = 76

Step(ii):-

Null hypothesis:H₀: μ = 43

Alternative Hypothesis: H₁: μ ≠ 43

Test statistic

           [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

          [tex]Z = \frac{47-43 }{\frac{25}{\sqrt{76} } }[/tex]

          Z = 1.39

Level of significance = 0.05

The critical value = 1.96

Final answer:-

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Answer:

x = 1/2 y = -1/3

Step-by-step explanation:

Split it into 2 equations:

10x-9y=8

and

21y+15x=0.5

10x - 9y = 8

Step 1: Divide both sides by 10:

x = (8+9y)/(10)

Substitute x = (8+9y)/(10) into 21y+15x=0.5 :

21y + (3(8+9))/(2) = 0.5

Solve for y

y= -1/3

Substitute y= -1/3 into x = (8+9y)/(10)

x = 1/2
