The length of given sides BC = 38 and EF = 38.
Given:
ΔABC ≅ ΔDEF
BC = x + 30 , EF = 4x + 6
we know that
BC = EF
x + 30 = 4x + 6
30 - 6 = 4x - x
24 = 3x
divide by 3 on both sides
3x/3 = 24/3
x = 8
BC = x + 30
= 8 + 30
= 38
EF = 4x + 6
= 4*8 + 6
= 32+6
= 38
Therefore the length of given sides BC = 38 and EF = 38.

On your way back you have toride 3 miles per hour slower (you're weighed down by your Wawa goodies) and ittakes you 0.5 hours. How far is it from your house to Wawa?6. Laura retired from her job recently, and she has saved about $500,000 over the
Let y represent the distance from your house to wawa. This means that the distance from wawa to your house is also y miles.
It takes you 0.4 hours at x miles per hour to make it to Wawa.
Distance = speed * time
Therefore, on your way to wawa, the expression would be
y = 0.4 * x = 0.4x
On your way back you have to ride 3 miles per hour slower. This means that your speed was (x - 3) miles per hour. Since it took you 0.5 hours, the expression for distance would be
y = 0.5(x - 3)
Since the distance is the same, it means that
0.4x = 0.5(x - 3)
0.4x = 0.5x - 1.5
0.5x - 0.4x = 1.5
0.1x = 1.5
x = 1.5/0.1
x = 15
Therefore,
y = 0.4x = 0.4 * 15
y = 6
The distance from your house to wawa is 6 miles
What is the solution to the inequality x(x – 3) > 0?Question 8 options:A) x ≤ 0 or x ≥ 3B) x < 0 or x > 3C) x ≤ 0 and x ≥ 3D) 0 < x < 3
,Inequalities
It's given the inequality:
x(x - 3) > 0
Note the left side is the product of two expressions: x and x-3.
That product must be greater than zero, or positive.
Recall that the product of two numbers is positive in two different cases:
Both are positive, for example 5*4=20
Both are negative, for example (-5)*(-4) = 20
This means that we can provide two different answers to the inequality, both valid:
1. When x >0 AND x - 3 >0 (both positive), or
2. When x <0 AND x - 3 < 0 (both negative).
The first condition leads to:
x>0 AND x>3. If we intersect these conditions, the solution for this part is x>3.
The second condition gives us:
x<0 AND x<3. The intersection of these conditions gives x<0.
Thus, the final solution is the union (OR) both partial intervals above, i.e.
x>3 OR x<0 --> Option B)
Answer:
X < 0 and x > 3.

What is (6/7)/(2/7)?
To find the value of;
[tex]\frac{(\frac{6}{7})}{(\frac{2}{7})}[/tex]When dividing fractions, for example a divided by b is equals a times 1/b;
[tex]a\text{ divided by b = a }\times\frac{1}{b}[/tex]note that the divisor which is b is inversed and multiplied.
So, let us apply the same rule to the given question.
The divisor which is the second fraction for the question is 2/7, we need to inverse 2/7 and multiply it by the first fraction.
The inverse of 2/7 is 7/2, So;
[tex]\frac{(\frac{6}{7})}{(\frac{2}{7})}=\text{ }\frac{6}{7}\times\frac{7}{2}=\frac{(6\times7)}{(7\times2)}=\frac{42}{14}[/tex]And finally;
[tex]\frac{42}{14}=3[/tex]Therefore the final answer is 3.

the sum of three consecutive integers is 267.what is that largest interger
The sum of three consecutive integers is 267. If the first one is a, then the second would be a + 1, while the third would be a + 2. Therefore, you would have;
[tex]\begin{gathered} a+(a+1)+(a+2)=267 \\ a+a+1+a+2=267 \\ 3a+3=267 \\ \text{Subtract 3 from both sides} \\ 3a=264 \\ \text{Divide both sides by 3} \\ a=88 \end{gathered}[/tex]The largest (third) integer is a + 2, therefore
[tex]\begin{gathered} a+2=88+2 \\ a+2=90 \end{gathered}[/tex]The largest integer therefore is 90.
pan made a scale drawing of a swimming pool. The diving board is 2 inches long in the drawing. The actual diving board is 18 feet long. What scale did Pam use for the drawing?
Divide the length of the object on the drawing by its actual size to find the scale:
[tex]\frac{2\text{ inches}}{18\text{ feet}}[/tex]Since each feet has 12 inches:
[tex]\frac{2\text{ inches}}{18\text{ feet}}=\frac{2\text{ inches}}{18\cdot12\text{ inches}}=\frac{2}{216}=\frac{1}{108}[/tex]Therefore, the scale used in the drawing is 1:108 (one inch in the paper equals 108 inches in real life).
which line is steeper y=+2 or y= -7/3x -5
The inclination of the lines in the coordinate system is given by their slopes, so to determine which line is steeper you have to compare the absolute values of both slopes.
The first equation y=2 has no slope, if you draw it you will see that for any value of x, y doesn't change, it is always 2.
You can also say that the slope of this equation is equal to zero.
For the second equation y=-7/3x-5, the slope is equal to -7/3.
The second equation is steeper than the first one since the absolute value of its slope is greater.

Jane has a pre-paid cell phone with A Fee and Fee. She can't remember the exact costs, but her plan has a monthly fee and a charge for each minute of calling time. In June she used 430 minutes and the cost was $227.50. In July she used 780 minutes and the cost was $385.00.
Given:
the plan of the pre-paid cell phone
The plan has a monthly fee and a charge for each minute
Let the monthly cost = C
and the number of minutes = x
the general equation will be:
C = ax + b
Where (b) is the monthly fee, and (a) is the charge per minute
We will find the values of (a) and (b) using the following:
1) 430 minutes cost $227.50
2) 780 minutes cost $385.00.
So, we have the following equations:
[tex]\begin{gathered} 430a+b=227.5\rightarrow(1) \\ 780a+b=385\rightarrow(2) \end{gathered}[/tex]Solve the equations, subtract equation (1) from (2) to eliminate (b), and solve for (a):
[tex]\begin{gathered} 780a-430a=385-227.5 \\ 350a=157.5 \\ a=\frac{157.5}{350}=0.45 \end{gathered}[/tex]Substitute with (a) into equation (1) to find the value of (b)
[tex]\begin{gathered} 430\cdot0.45+b=227.5 \\ 193.5+b=227.5 \\ b=227.5-193.5=34 \end{gathered}[/tex]So, the equation of the monthly cost will be:
[tex]C=0.45x+34[/tex]Part (b): When x = 484 minutes, we will find C
so, substitute with (x) into the equation of C
[tex]\begin{gathered} C=0.45\times484+34 \\ C=217.8+34 \\ C=251.8 \end{gathered}[/tex]So, the answer will be:

Recall that:
Interest is the monetary gain for lending money to a third party.
Simple interest is applying the interest to the original amount without considering the extra flow of money each time the interest is applied.
Compounded interest is applying the interest to the total amount including the extra flow of money each time the interest is applied.
1) Plan A. From the given information, in 12 months Ari will earn:
[tex]I=500\cdot0.065\cdot12=390.[/tex]dollars, therefore she will have a total of $890.00.
2) Plan B. Now we use the formula for compounded interest to compute the total amount that Ari will have after one year:
[tex]A=500(1+0.065)^{12}=500\cdot2.129096\approx1064.55.[/tex]3) From the above calculations, we conclude that Ari will make more money if she invests in plan B.
4) Ari has to leave the money for another:
Using plan B. Let t be the number of extra months Ari needs to leave the money in the fund, then:
[tex]1100=500\cdot(1.065)^{12+t}\text{.}[/tex]Solving for t, we get:
[tex]\begin{gathered} 1.065^{12+t}=2.2, \\ (12+t)ln(1.065)=\ln (2.2), \\ 12+t=\frac{\ln (2.2)}{\ln (1.065)}=12.52, \\ t=12.52-12=0.52. \end{gathered}[/tex]Then, Ari needs to leave the money for another half a month but since the interest is applied each month she needs to leave the money for another whole month.
Using Plan A: Let t be the number of extra months Ari needs to leave the money in the fund, then:
[tex]1100=500\cdot0.065\cdot(12+t)\text{ +500.}[/tex]Solving for t we get:
[tex]\begin{gathered} \frac{1100-500}{500\cdot0.065}=12+t, \\ t=\frac{600}{32.5}-12, \\ t=6.46. \end{gathered}[/tex]Then, Ari needs to leave the money for another 6.46 months but since the interest is applied monthly she needs to leave the money for another 7 months.

GIVEN: P(N) = 0.25 and P(R) = 0.6If the probability of P(N R) = 0.15, are N and Rindependent events?a) Yes, because P(N) + P(R) +0.15b) No, because P(N).P(R) +0.15c) Yes, because P(N) X P(R) = 0.15d) Not enough information
P(N∩R) represents the probability of A and B.
When two events are independent events, the joint probability is calculated by multiplying their individual probabilities.
P(N∩R) For independent events:
[tex]P\mleft(N\cap R\mright)=P(N)\times P(R)[/tex]Substituting the known values for P(N) and P(R):
[tex]\begin{gathered} P(N\cap R)=0.25\times0.6 \\ P(N\cap R)=0.15 \end{gathered}[/tex]0.15 is the value of P(N∩R) given by the problem, and since we get the same result using the formula for independent events, we can affirm that N and R independent events.

[tex]\begin{gathered} 4x+14=42 \\ 4x=42-14 \\ 4x=28 \\ x=\frac{28}{4} \\ x=7 \end{gathered}[/tex]Answer: the equation is 4x+14=42 and the solution is x=7
Find the maximum value of the objective function and the values of x and y for which it occurs. F= 2x+y3x+5y ≤45 x ≥0 and y ≥02x+4y ≤32The maximum value of the objective function is ______.
The objective function is:
[tex]F=2x+y[/tex]We need to find the shaded region where 4 inequalities overlap, then we need to graph the given inequalities:
[tex]\begin{gathered} 3x+5y\leq45 \\ 5y\leq-3x+45 \\ y\leq\frac{-3}{5}x+\frac{45}{5} \\ y\leq-\frac{3}{5}x+9 \end{gathered}[/tex]And the other one:
[tex]\begin{gathered} 2x+4y\leq32 \\ 4y\leq-2x+32 \\ y\leq\frac{-2x}{4}+\frac{32}{4} \\ y\leq-\frac{1}{2}x+8 \end{gathered}[/tex]And x>=0, y>=0
The graph is:
The coordinates of the shaded region are then:
(0,0), (0,8), (10,3) and (15,0)
To obtain the maximum value, let's evaluate the objective function in all the coordinates:
[tex]\begin{gathered} F(0,0)=2\times0+0=0+0=0 \\ F(0,8)=2\times0+8=0+8=8 \\ F(10,3)=2\times10+3=20+3=23 \\ F(15,0)=2\times15+0=30+0=30 \end{gathered}[/tex]Then, the maximum value is the largest value obtained, then it's 30 and it occurs at x=15 and y=0.
