I need help with this geometry question
Answer:
x=9; JL= 23
Step-by-step explanation:
To find x:
If JL and KM are equivalent, then JL = KM. Substitute the equations and you get 2x+5 = 7x-40.
Put the similar terms on the same side by subtracting 2x from both sides and adding 40 to both sides. You will get 45=5x.
Get x alone by dividing both sides by 5 and you will get 9=x.
To find JL:
Substitute the x in 2x+5 (JL length equation) with 9. Your new equation will be 2(9) + 5.
2•9 = 18.
18+5=23

Answer:
C. SAS
Step-by-step explanation:
If you look at both of the triangles carefully, you will see that both side AB and side DC have the same amount of lines. Since they have the same sides, the angle that they share would equal each other as well. The last side is obviously equal to each other because they are the same.
SSS, because all of the sides are the same ; AC = BD , AB = CD , and they both share side BC

A biologist studied the frequency of croaks for frogs from two different regions. From a random sample of 32 frogs located in the northern region, the mean number of croaks per hour was 21.3, and from a random sample of 38 frogs located in the southern region, the mean number of croaks per hour was 28.9. To estimate the difference in the mean number of croaks (southern minus northern), a 95 percent confidence interval was constructed from the samples. The interval was reported as (7.1, 8.1). Which of the following claims is supported by the interval?
A. All southern frogs croak more times per hour than do all northern frogs.
B. The northern frogs are likely to have a greater mean number of croaks per hour than the southern frogs.
C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.
D. All frogs in the study have about the same number of croaks per hour.
E. The northern and southern frogs have the same mean number of croaks per hour.
Answer:
C
Step-by-step explanation:
Since at the 95% confidence, the difference between the number of croaks per hour between southern and northern region frog is lying in the rage 7.1 to 8.1, this shows that the southern region's frogs' croak frequency is highly likely to be greater than that of northern region's frogs' croaks' frequency.
The claim supported by the interval is
Option C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.
What does the interval tell obtained in the hypothesis testing?The interval we obtain at certain confidence tells that the value of the test statistics will lie in that interval with that confidence.
How to identify what is the obtained interval indicating?Since the test statistics was measuring the croak frequency difference
with southern - northern, and since at 95% confidence, the difference will lie in interval (7.1, 8.1), which is positive, thus the frequency of crocks for southern frogs is greater than the frequency of crocks for northern frogs.
Thus,
The claim supported by the interval is
Option C. The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

A series of maths books consists of four volumes. The first has x pages and the second has 54 more. The third and fourth volumes have 32 more pages than the second volume. The number of pages of all volumes is 866. Calculate the number of pages in each volume.
Answer:
1st volume = 160
2nd volume = 160 + 54 = 214
3rd volume = 160 + 54 + 32 = 246
4th volume = x + 54 + 32 = 246
Step-by-step explanation:
Given that:
Number of volumes = 4
1st volume = x pages
2nd volume = 54 more = x + 54
3rd volume = 32 more = x + 54 + 32
4th volume = 32 more = x + 54 + 32
Total number of pages = 866
Hence,
1st + 2nd + 3rd + 4th = 866
x + x + 54 + x + 54 + 32 + x + 54 + 32 = 866
4x + 226 = 866
4x = 640
x = 160
1st volume = 160
2nd volume = 160 + 54 = 214
3rd volume = 160 + 54 + 32 = 246
4th volume = x + 54 + 32 = 246

1: 7(3+5) = ? + ?
2: 15 - 10 = ? (3-2)
Please hurry I have to submit this by 3:00
Answer: 1. 7(3+5)= 21+35
2. 15 - 10 = 5 (3-2)
Step-by-step explanation:
1: 7(3+5) = ? + ?
Opening the bracket and multiplying each number by 7
7 x 3 + 7 x 5 = 21 + 35 =56
7(3+5)= 21+35
2.15 - 10 = ? (3-2)
15- 10 = 5 , On the other hand,
3-2 = 1
to make the left hand equivalent to the right hand side , we multiply the difference gotten from 3-2 by 5 so we have
15 - 10 = 5 (3-2)
5=5(1)
5=5
ASAP need help with system of equations... I'm too small brain to do it.
Answer:
(x=0, y=11)
(x=2, y=9)
Step-by-step explanation:
first equation substitution for x first.
y=11-x
plug into 2nd equation
(x+2)^2+(11-x-7)^2=20
this should lead you into a quadratics equation.
you get x=0, x=2.
do the same for y value this time, subbing in the x value
(11-y+2)^2+(y-7)^2=20
this also leads into a quad equation
solve and you get y=11, and y=9

Estimate the time Juanita will arrive at her aunt's home 320 miles away if she leaves at 9:00 a.m., drives about 60 miles per hour, and stops
for a 40 minute break halfway.
A 12:00 p.m.
B. 1:00 p.m.
c. 2:00 p.m.
D. 3:00 p.m.
E. 4:00 p.m.
Answer:
D. 3:00 p.m.
Step-by-step explanation:
d = Distance = 320 miles
s = Speed = [tex]60\ \text{mph}=\dfrac{60}{3600}=\dfrac{1}{60}\ \text{miles/s}[/tex]
Time taken is given by
[tex]t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{320}{\dfrac{1}{60}}\\\Rightarrow t=19200\ \text{s}[/tex]
40 minutes break is [tex]40\times 60=2400\ \text{s}[/tex]
Total time taken is [tex]19200+2400=21600\ \text{s}=\dfrac{21600}{60\times 60}=6\ \text{hours}[/tex].
So, the entire trip took 6 hours. 6 hours after 9 a.m. is 3 p.m.

If y=-4+11 and 3x+y=9 what is the value of y?
Answer:
y = 7
x = 2/3
Step-by-step explanation:
hope it help
plz follow me
Answer:
2/3
Step-by-step explanation:
We know the value of y, so substitute y into the equation:
3x + (-4 + 11) = 9 --> remove parentheses
3x - 4 + 11 = 9
3x + 7 = 9 --> subtract 7 from 9
3x = 2 --> divide
x = 2/3
3. What is the perimeter of a rectangle if the width is 2 ½ inches and the length is 4.5 inches?
(show how you get your answer please)
Answer:
Perimeter of the rectangle = 14 inches
Step-by-step explanation:
Step(i):-
Given length of the rectangle = 4.5 inches
Given that the width of the rectangle = [tex]2\frac{1}{2} = \frac{5}{2} = 2.5[/tex] inches
The area of the rectangle = length × width
= 4.5 × 2.5
= 11.25 sq inches
Step(ii):-
Perimeter of the rectangle = 2( length + width)
= 2( 4.5 + 2.5)
= 14 inches
Final answer:-
Perimeter of the rectangle = 14 inches

To be able to solve clearly this problem, the best thing to do is to plot the graph (see attached pic). From the graph we can see that the points form a trapezoid.
The base is formed by the segment connecting point A and point B.
While the two heights: shorter one by the segment connecting points A and D, and the longer one by the segment connecting points B and C.
The formula for area of trapezoid is given as:
A = b (h1 + h2) / 2
Where,
b = base of the trapezoid = 3 – (-4) = 7
h1 = shorter height = 2 – (-2) = 4
h2 = longer height = 2 – (-5) = 7
Therefore the area is:
A = 7 (4 + 7) / 2
A = 77 / 2
A = 38.5

Julio invest $15,000 in a savings account that pays 1.5% simple interest. How much will be in the
account after 5 years if Julio makes no withdrawals or deposits? *
Answer: Final amount
Step-by-step explanation:
Final amount = Simple interest + Principal
=Principal x Rate x Time + Principal
= Principal (Rate x Time +1) [Simple interest =Principal x Rate x Time]
Given: Principal = $15,000, Rate = 1.5% = 0.015 [To conver % into decimal we divide it by 100]
Time = 5 years
Final amount = $(15000(0.015 ×5+1))
=$ (15000×1.075)
=$ 16125
Hence, there will be $16,125 in the account after 5 years if Julio makes no withdrawals or deposit.
