5/8 × 144 = 90

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:

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:

you need to subtract 23 from 33 to find x

Step-by-step explanation:

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:

Lowest common denominator are

Answer:

35  :  7

5    :  1 ( if u need ur answer in simplest form )

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.

For d. measure of angle 1 is 45 and measure of angle 2 is 45 degrees

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

Step-by-step explanation:

456÷12= 38

95÷38= 2.447 (about 2.5)

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:

friend has 9, Veronica has 23

Step-by-step explanation:

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:

The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect.  This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.

Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes.  Because K and M are on the same Y coordinate (-4), lets do this for LM and KL

First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.

The slope is the change in Y over the change in X

Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2

Slope KL =  -4-(6) / 4-2 = -10/2 = -5

The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for

the slope of K⊥LM has to be 1/2 and

the slope of M⊥KL has to be 1/5

Second, the vertex has to be on a line with that slope.  So using the point-slope formula

(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us

K⊥LM:  y-(-4) = 1/2(x-4)

M⊥KL:  y-(-4) = 1/5(x-7)

Third, find the point on both lines, are where the two equations are equal

So, 1/2(x)-2 = 1/5(x) - 7/5;

5x - 20 = 2x - 14

3x = 6 --> x=2

y+4=-1 --> y=-5

Answer:

25m

Step-by-step explanation:

Shannon's rate is 2,500m/100min. Simplifying, we see that this is equal to 25m/1min.

So, she walks 25 m in one minute.

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.
