Answer:

See step by step

Step-by-step explanation:

For A. use any two factors that multiply to 100 that isn't 25 and 4.

For b Use one obtuse angle (angle over 90 degree) and two acute angles. Make sure they add up to 180.

For c Use any two values that add up to 52 since they didnt establish y as the midpoint.

Veronica= 2x +5

friend = x

2x+5+x= 32

combine like terms

3x+5=32

move 5 to the other side

3x= 27

divide by 3

x=9

Answer: -7√61/61

Step-by-step explanation:

I got the answer wrong on my test and this was the correct answer shown.

The cosine of the terminal ray of angle β comes to be -7/√61.

The cosine of an angle is the ratio of the adjacent side to the hypotenuse.

By Pythagoras' theorem

Hypotenuse² = 7²+(2√3)²

Hypotenuse =√61

From the diagram attached

[tex]Cos(180-\beta )=\frac{7}{\sqrt{61} }[/tex]

We know [tex]Cos(180-\beta )=-Cos\beta[/tex]

[tex]-Cos\beta =\frac{7}{\sqrt{61} }[/tex]

[tex]Cos\beta =\frac{-7}{\sqrt{61} }[/tex]

So, the value of cosβ =-7/√61.

Hence, The cosine of the terminal ray of angle β comes to be -7/√61.

Answer: B= 12 15

Step-by-step explanation:

The given ratios are

A) 2 3= 2: 3  already in its simplest form

B)  12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us           4:5

C)  18 27 =18: 27  Changing to its simplest form, we divide both numbers by 9 giving us =2:3        

D)6 9=6:9  Changing to its simplest form, we divide both by 3 giving us  

       2:3

Therefore the ratio not equivalent to other three is 12:15

Answer:

x is 13

y is 39

Step-by-step explanation:

Answer:

y= 39  x= 10

Step-by-step explanation:

congruent isosceles triangles

longer sides measure the same  13 and 13    39 and 39 ( y =39)

39/30  = 13/x

cross multiplication:

39x = 13x30

39x = 390

x=10

Answer: 30

Step-by-step explanation:

9/10 = numerator 9 x 3 = 27 and  denominator 10 x 3 = 30

2/15 = numerator 2 x 2 = 4 demoninator 15x 2 = 30

This is to make it easier to subtract with a common denominator

= 27-4/ 30

= 23/30

the lowest common denominator is 30

Answer:

16 dimes

Step-by-step explanation:

D=number of dimes

Q=number of quarters

D+Q=37

.25 xQ + .10 x D=6.85

sub Q from first equation

.25(37-D) + .10 x D=6.85

D(.10-.25) + .25 x 37 =6.85

-.15D + 9.25=6.85

D= (6.85-9.25)/(-.15)

D=16

Answer:

r = 24

Step-by-step explanation:

3(r+2)+5(2−r)=−32

Step 1: Simplify both sides of the equation.

3(r+2)+5(2−r)=−32

(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)

3r+6+10+−5r=−32

(3r+−5r)+(6+10)=−32(Combine Like Terms)

−2r+16=−32

−2r+16=−32

Step 2: Subtract 16 from both sides.

−2r+16−16=−32−16

−2r=−48

Step 3: Divide both sides by -2.

−2r/-2 = -48/-2

r = 24  

Answer: r = 24

3(r+2)+5(2-r) =-32

this equals (if we do the multiplication)

3r+6+10-5r=-32

this equals  (if we simplify)

-2r+16=-32

this equals  (because we are subtracting from 1 side, we must subtract from the other)

-2r=-48

r=24

Answer:

1 cubic centimetre =1 × 10^-6 cubic metre

Step-by-step explanation:

A cube that has a length of 1cm on each side has a volume of 1 cm. How many cubic centimeters are in 1 cubic meter? (Hint: The answer is not 100.)

From the above question,

Side length of the cube = 1cm

Volume of the cube = (side length)³

= (1cm)³

= 1 cm³

How many cubic centimeters are in 1 cubic meter?

Note that:

100 cm = 1 m

1 cm³ = x m³

1 cm³ = (1/100 × 100 × 100)m³

1 cm³ = 1 × 10^-6 m³

Therefore,

1 cubic centimetre =1 × 10^-6 cubic metre
