Answer:

Step-by-step explanation:

Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z

Note that sin theta = cos(90-thetsa)

sin(9z − 1) = cos(6z + 1)

cos (90 - (9z-1)) = cos(6z + 1)

cos (90 - 9z+1)) = cos(6z + 1)

cos (91-9z) = cos(6z + 1)

Cos will cancel out to have;

91-9z = 6z+1

-9z - 6z = 1-91

-15z = -90

z = 90/15

z = 6

Hence the value of z is 6

I'm sure is a correct answer

Answer:

3 = ?

Step-by-step explanation:

The triangles are similar, so we  can use ratios

15           12 -2

------   = --------------

15+?          12

15           10

------   = --------------

15+?          12

Using cross products

15 * 12 = 10 ( 15+?)

180 = 10 ( 15+?)

Divide each side by 10

18 = 15+?

Subtract 15 from each side

18-15 = 15+?-15

3 = ?

yes

yes!

Step-by-step explanation:

4 + 15 = 19

1 + 15 = 16

hope that helped! i'm not the best at explaining stuff, srry!

Step-by-step explanation:

If x=20 3x/5=12

Then if y=30 3y/5=18

It shows that A'B'C' smaller than ABC

Answer:

The correct statement is D

Step-by-step explanation:

Triangle A'B'C' is a diluted version of triangle ABC, so it would be smaller than triangle ABC since its x-value and y-value are being multiplied by a number less than 1.

I didn't understand your question.

Answer:

8

Step-by-step explanation:

7 and 8 are the angles so we need to find the decimal in the problem

Answer:

4) [tex]3\sqrt{3}[/tex] 5) [tex]10\sqrt{18}[/tex]

Step-by-step explanation:

[tex]27[/tex] can be broken down into [tex]3[/tex] and [tex]9[/tex]

[tex]\sqrt{27}=[/tex][tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]

However, [tex]\sqrt{9} =3[/tex], so its really just:

[tex]3\sqrt{3}[/tex]

[tex]1800[/tex] can be broken down into [tex]100[/tex] and [tex]18[/tex]

[tex]\sqrt{1800} =[/tex][tex]\sqrt{100}[/tex] × [tex]\sqrt{18}[/tex]

However, [tex]\sqrt{100} =10[/tex], so it is really:

[tex]10\sqrt{18}[/tex]

porque incremento de un día

Answer:

1 hour and 45 minutes

and 1 hour

Step-by-step explanation:

x= run

y= walk

5x+2.5y = distance

5x+2.5(1.5)=12.5

solve for x

5x=8.75

x=1.75

1.75 in hours is 1 hour and (60*.75)=45

1 hour and 45 minutes

" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"

We use the same equation

5x+2.5y=distance

we'll assume that they till walked 12.5 miles

which means that

5(2)+2.5y=12.5

solve for y

2.5=2.5y

y=1

1 hour

Answer:

141

Step-by-step explanation:

Answer:

141

Step-by-step explanation:

Find the third angle in the triangle and using the rule that all supplementarly angles are 180 degrees, subtract the third angle from 180.

180-87-54=39, 39 is the third angle of the triangle

180-39=141 degrees, x= 141

Answer:

x = 30

Step-by-step explanation:

So, you want to get 'x' by itself

0.25x + 7.5 = 15

           - 7.5   -7.5

0.25x = 7.5

---------   ------

0.25     0.25

x = 30

Answer:

14.4

Step-by-step explanation:

Area= 72 cm^2

Base= 10 cm

height= ?

Area= base x 1/2 x height

72 = 10 x 1/2 x h

72= 5 x h

72/5 = h

h= 14.4

Answer:

Doesn't factor

Step-by-step explanation:

We have a polynomial and are asked to factor it.

A rule I like to follow when factoring polynomials is what two numbers multiply to equal c (in this case -2) and add up to b (in this case -6x).

Since no two numbers are eligible to do this, therefore this polynomial is unfactorable.

Step-by-step explanation:

Answer:

The answer is D. choice B. The coordinate point CAN share the same y point but, CANNOT share the same x point

Step-by-step explanation:

For all values of x, y = - 6

Your function:

y = - 6

Answer:

(-7,-9) and (7,9)

Step-by-step explanation:7,-9 so we do across the x so you need a graph for this now x goes left so we plot the coordinates in the third box 7,-9 is in the 4 box so after we plotted that you can see it reflects.Now y coordinate since the y line goes up we plot the coordinates on top of the 4 box where our original coordinates stay now it should be 7,9 the y becomes positive which is 9.

z=27

Step-by-step explanation:

there u go

Answer:

23) x -3 = 9

x=9+3=12

24) y-11=23

y=23+11=34

25) z-8=37

z=37+8=45

26) m-16=17

m=17+16=33
