Answer is B

Answer:

Step-by-step explanation:

3) ΔABC ≅ ΔDEF

AB = ED   {Corresponding parts of corresponding  triangles are equal}

6y - 4 = 4y +2

add 4 to both sides

6y - 4 + 4 = 4y + 2 + 4

6y = 4y + 6

subtract 4y from both sides

6y - 4y = 4y + 6 - 4y

2y = 6

Divide by 2

[tex]\frac{2y}{2}=\frac{6}{2}\\[/tex]

y = 3

AB = 6y - 4 = 6*3 - 4 = 18 - 4 =14

AB = 14

ΔABC ≅ ΔDEF

∠A = ∠D   {Corresponding parts of corresponding  triangles are equal}

5x + 2 =87

5x = 87 - 2

5x = 85

x = 85/5

x = 17

In ΔDEF,

∠D + ∠E + ∠F = 180°   {SUM OF ALL ANGLES OF TRIANGLES}

87 +  42 + ∠F = 180  

129 + ∠F = 180°

∠F = 180 - 129

∠F =  51°

ΔABC ≅ ΔDEF

∠C = ∠F   {Corresponding parts of corresponding  triangles are equal}

3y = 51

y= 51/3

y = 17

Answer:She walk the dogs for 3 hours and then she worked 5 hours landscaping for last week

Step-by-step explanation:We call X the hours she walk the dog

so the time that she do the landscaping is (8-X)

Put into equation we have 6x+13(8-x)=83

there we have x is 3

Kaylee worked 3 hours walking dogs and 5 hours landscaping last week.

This problem is a system of linear equations which we can solve using substitution or elimination method. But let's use the substitution method for this particular problem. Let's denote the number of hours Kaylee worked walking dogs as x and the number of hours she worked landscaping as y.

So from the problem we have 2 equations:

From the first equation y = 8 - x. Substitute y in the second equation by (8 - x): 6x + 13(8 - x) = 83. By solving this equation we find x = 3 Substitute x = 3 in the first equation we find y = 5.

So, Kaylee worked 3 hours walking dogs and 5 hours landscaping last week.

Answer: Radius= 12cm Diameter= 24cm

Step-by-step explanation:

The music store will charge $5 for a yearly membership.

Step-by-step explanation:

Let the cost per vinyl album be 'a'

Let the yearly membership cost be 'b'

Given that,

4a + b = 35

7a + b = 57.5

9a + b = 72.5

We can take any 2 equations from the above,

(4a + b = 35 ) - (7a +b =57.5)

4a + b - 7a - b = 35 - 57.5

-3a = -22. 5

3a = 22.5

a = 7.5

The cost of each vinyl album is $7.5

4a + b = 35

4(7.5) + b = 35

30 + b = 35

b = 35 - 30

b = 5

The cost of the yearly membership is $5

The music store will charge $5 for a yearly membership.

Answer:

Step-by-step explanation:

2x ≥ 4

Divide by 2

2x/2 ≥ 4/2

x ≥ 2

-x+7<-6

Subtract 7 from each side

-x+7-7<-6-7

-x < -13

Divide each side by -1, remembering to flip the inequality

x > 13

y>-x+3

This is a line with slope -1 and y intercept 3

This is a dotted line since there is no equals sign and graph above

Answer:

2x ≥ 4

x ≥ 2

-x+7<-6

-x < - 13

x > 13

Region towards right of x = 13, with x = 13 being dotted

y > -x + 3

Draw a dotted line passing through (0,3) and (3,0)

Shade the region above this line which is towards right of x = 13

Step-by-step explanation:

law of cosines states that [tex]c^{2} =a^{2} +b^{2} -2ab (cos(\alpha ))[/tex]

so we know that a = 7, b = 4, and alpha would be 135 degrees, so just plugging it in gets us 49+16-2*7*4*(-0.707) = 65 + 39.59 = 104.59

The number of games played is 9

Let the number of games played = g

Amount of bet per game = $2

Number of games won by Marty = 4

Number of games won by Wendy will be;

Amount won by Wendy = $10

This means ;

cost per bet × number of games won by Wendy = 10

2(g - 4) = 10

2g - 8 = 10

2g = 18

g = 9

Hence, They played 9 games.

To find the fourth term in the sequence described by the expression c(n)=-7+6(-1), substitute n = 4 into the expression and simplify.  the fourth term in the sequence is -13.

To find the fourth term in the sequence given by c(n)=-7+6(-1), we need to substitute n = 4 into the expression and simplify.

First, substitute n = 4 into the expression:

c(4) = -7 + 6(-1)

Next, simplify the expression:

c(4) = -7 + (-6)

c(4) = -7 - 6

c(4) = -13

Therefore, the fourth term in the sequence is -13.

Assuming original commercials were 30 seconds long, during a 3.6-minute break, 7 commercials could fit. If they are half as long, or 15 seconds each, then 14 commercials could fit in the same time period.

The question is asking to calculate how many commercials will play during a commercial break that lasts 3.6 minutes if the commercials are half as long as the ones during the original break. To calculate this, you need to know the length of the original commercials. However, since this information was not provided in the question, let's for example assume that the original commercials were 30 seconds long each (a common commercial length).

If the original commercials were 30 seconds long, then during a 3.6-minute break (which converts to 216 seconds), you could fit in 216 / 30 = 7.2, which is not possible since you can't have a fraction of a commercial. So, you would normally have 7 commercials during the break.

If the new commercials are half as long, meaning they are 15 seconds each, then during the same 3.6-minute break, you could fit in 216 / 15 = 14.4, which again is not possible, so you would have 14 commercials play during the break since you can't have a fraction of a commercial.

In mathematics, the sign of a rational number is determined by the signs of the numerator and the denominator. If both the numerator and the denominator are of same sign (either positive or negative), the rational number is positive. If they have different signs (one positive, one negative), the rational number is negative.

According to the rules of mathematics, the sign of a rational number is determined by the signs of the numerator and the denominator. If both are positive or both are negative, the resulting number is positive. If one is positive and the other is negative, the result is negative.

Answer:

Y = -7x+7

Step-by-step explanation:

(This takes a while)

A) Y = 7x - 7

B) Y = 7x + 7

C) Y = -7x + 7

D) Y = - 7x - 7

The asnwer is: C.

Because by distribution the numbers of [x], you will find that you will get [y]. And when you must do this with each of them in order to find out which is the right function.

(6,-35) -> Subsitute 6 into [x]:

Y = 7(6) - 7

Y = 42 - 7

Y = 35

This is wrong, because [y] is supposed to equal -35 and not 35. So A. is out.

B. is also positive, so that means you can't get a negative from it either, so that's out.

C. and D. are both negative, so its between these two.

Y = -7x + 7

Y = -7(6) +7

Y = -42 +7

Y = -35 <- Okay, so that's correct, now let's check D.

Y = -7(6) - 7

Y = -42 - 7

Y = -49 <- This answer is wrong, so your correct answer is C!

Step-by-step explanation:

0.36

36/100

18/50

9/25

Answer:

Step-by-step explanation:

     ____

a) 0.36   = 0.3636........    

x = 0.363636.......    

{After decimal two digits are there and both are repeated. So, multiply both side by 100}

100x = 36.3636.......  equ(i)

    x =   0.3636......   equ(ii)   {Now, subtract equ (ii) form (i)

99x  = 36

x = 36/99

x = 4/11

0.3636...... = 4/11

B)    __

 0.36     = 0.366666.....

{After decimal point two digits are there but only one digit, 6 is repeated. so first multiply both sides of equation [x=0.366...] by 100 and mark it as equation (i) and then multiply both sides of the equation [x=0.366...] by 10 and mark it as (ii) equation }

x = 0.3666....

100x = 36.66666.....     ---------- (i)

10x  =    3.66666......      ---------(ii)  {Now subtract (ii) from (i)}

90x = 33

x = 33/90

x = 11/30

0.36666..... = 11/30

Step-by-step explanation:

nnnnnnnxnxnxnx

The population of rabbits in the year 2025 will be 3172.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have in 2010, there were 1000 rabbits on an island. The population grows 8% every year.

Assume that the population in the year 2025 be [x]. We can write he annual growth multiplicative factor as 1.08. Now -

x = 1000(1.08)¹⁵

x = 3172

Therefore, the population of rabbits in the year 2025 will be 3172.
