If one number is five more than another number, and the smaller number is half of the larger number, what are the two numbers?
Answer:
Larger number = 10Smaller number = 5Step-by-step explanation:
Let larger number be x
Let smaller number be y
[tex]x = 5 + y[/tex]---> equation (i)
[tex]y = \frac{1}{2} x[/tex]
[tex]x = 2y[/tex]-----> equation (ii)
Equate equation (i) and (ii),
[tex]5 + y = 2y[/tex]
Move variable to L.H.S and change its sign:
Similarly, Move constant to R.H.S and change its sign
[tex]y - 2y = - 5[/tex]
[tex] - y = - 5[/tex]
The difference sign (-) will be cancelled on both sides
[tex]y = 5[/tex]
Putting the value of y in equation (ii) in order to find the value of X ( larger number)
[tex]x = 2y[/tex]
Plug the value of y
[tex] = 2 \times 5[/tex]
Calculate the product
[tex] = 10[/tex]
Hence,
Smaller number = 5
Larger number = 10
Hope this helps..

Answer:
10 and 5
Step-by-step explanation:
Let the first number be x.
Let the second number be y.
x = 5 + y
y = 1/2x
Plug y as 1/2x in the first equation.
x = 5 + (1/2x)
Solve for x.
Subtract 1/2x on both sides.
x - 1/2x = 5 + 1/2x - 1/2x
1/2x = 5
Multiply both sides by 2.
2(1/2x) = 2(5)
x = 10
Plug x as 10 in the second equation.
y = 1/2(10)
Solve for y.
y = 5
x = 10
y = 5
The two numbers are 10 and 5.
10 is the larger number.
5 is the smaller number.

Identify the CONCLUSION of a hypothesis test of the following claim and sample data: Claim: "The average annual household income in Warren County is $47,500." A random sample of 86 households from this county is obtained, and they have an average annual income of $48,061 with a standard deviation of $2,351. Test the claim at the 0.02 significance level.
Complete Question
The options for the above question is
a There is not sufficient evidence to warrant rejection of the claim.
b There is sufficient evidence to warrant rejection of the claim.
c There is sufficient evidence to support the claim.
d There is not sufficient evidence to support the claim.
Answer:
Option A is correct
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu =[/tex]$47,500
The sample size is [tex]n = 86[/tex]
The sample mean is [tex]\= x =[/tex]$48,061
The standard deviation is [tex]\sigma =[/tex]$2,351
The level of significance is [tex]\alpha = 0.02[/tex]
The null hypothesis is
[tex]H_o : \mu =[/tex]$47,500
The alternative hypothesis is
[tex]H_a : \mu \ne[/tex] $47,500
The critical value of [tex]\alpha[/tex] from the t-Distribution table is [tex]Z_{\frac{\alpha }{2} } = 2.326[/tex]
Now the test statistics is mathematically evaluated as
[tex]t = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]
substituting values
[tex]t = \frac{48061 - 47500 }{\frac{2351}{\sqrt{86} } }[/tex]
[tex]t = 2.21[/tex]
Now from the values obtained we can see that
[tex]Z_{\frac{\alpha }{2} } > t[/tex]
hence we fail to reject the null hypothesis
Hence there is not sufficient evidence to warrant rejection of the claim

CAN ANYONE HELP ME PLEASE? Jen Butler has been pricing Speed-Pass train fares for a group trip to New York. Three adults and four children must pay $106. Two adults and three children must pay $75. Find the price of the adult's ticket and the price of a child's ticket.
Answer:
adult=18$ and children=13$
Step-by-step explanation:
a= adult. and. c= children
first change the statement into linear equation
3a+4c=106
2a+3c=75
then it just solving for a and y
3a+4c=106. a= 75-3c.
2
3(75-3c)+ 4c=106. solve for c
2
c=13
then find c by substituting the value you got into a . you can you either 3a+4c=106
or 2a+3c=75 to find the answer but the value of a is the same.
2a+3c=75. c=13
2a+3(13)=75
2a=75 -39
2a= 36
a=18
Answer:
Adults Ticket = $18
Child's Ticket = $13
Step-by-step explanation:
Let A denote the price of an adult's ticket
Let C denote the price of a child's ticket
It is given that the three adults and four children must pay $106.
Mathematically,
[tex]3A + 4C = 106 \:\:\:\:\:\:\:\:\:\:\: eq. 1[/tex]
It is also given that the two adults and three children must pay $75.
Mathematically,
[tex]2A + 3C = 75 \\\\2A = 75 - 3C[/tex]
[tex]$ A = \frac{(75 - 3C)}{2} \:\:\:\:\:\:\: eq\:. 2 $[/tex]
Substitute eq. 2 into eq. 1
[tex]3A + 4C = 106[/tex]
[tex]$ \frac{3(75 - 3C)}{2} + 4C = 106 $[/tex]
Simplify,
[tex]$ \frac{3(75 - 3C)}{2} + 4C = 106 $[/tex]
[tex]$ \frac{225 - 9C}{2} + 4C = 106 $[/tex]
[tex]$ \frac{225 - 9C + 2(4C)}{2} = 106 $[/tex]
[tex]$ \frac{225 - 9C + 8C}{2} = 106 $[/tex]
[tex]$ 225 - 9C + 8C = 2(106) $[/tex]
[tex]$ 225 - C = 212 $[/tex]
[tex]C = 225 - 212[/tex]
[tex]C = \$13[/tex]
Substitute the value of C into eq. 2
[tex]$ A = \frac{75 - 3(13)}{2} $[/tex]
[tex]$ A = \frac{75 - 39}{2} $[/tex]
[tex]A = \$18[/tex]
Therefore, the price of the adult's ticket is $18 and the price of a child's ticket is $13

The class interval is $3Step-by-step explanation:
The class interval is simply the difference between the lower or upper class boundary or limit of a class and the lower or upper class boundary or limit of the next class.
In this case for the class
$4 up to $7 18 and
$7 up to $10 36
The lower class boundary of the first class is $4 and the lower class boundary of the second class is $7
Hence the class interval = $7-$4= $3Tim and Jim are working on a school project together. If he had to work by himself, it would take
Tim 10 hours to complete the school project. If Jim worked alone, it would take him 15 hours.
Working together, how long will it take Tim and Jim to complete the school project together?
Answer: 6 hours
Step-by-step explanation:
Given, Tim and Jim are working on a school project together.
Tim takes 10 hours to complete the school project.
If Jim worked alone, it would take him 15 hours
Let t be the time they both take if they work together.
Then, [tex]\dfrac{1}{t}=\dfrac{1}{\text{Time taken by Tim}}+\dfrac{1}{\text{Time taken by jim}}[/tex]
[tex]\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{10}+\dfrac{1}{15}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3+2}{30}=\dfrac{5}{30}\\\\\Rightarrow\dfrac{1}{t}=\dfrac{1}{6}\\\\\Rightarrow t=6[/tex]
So, it will take 6 hours to complete the school project together .
Help! PLZ, 20 PTS in 10 mins if possible thx !!!! A gym charges $55 for a monthly membership and an additional $4.50 for each yoga class a member attends. Simba can spend at most $70 at the gym each month. Write an inequality that shows the maximum number of yoga classes, y, that Simba can attend while staying within his gym budget. _________
Answer:
(70-55)/4.5=y rounded down to the nearest whole number
Step-by-step explanation:
The first step is to take away the $55 from $70
70-55=15
Simba has $15 to spend on the yoga classes, to find the number of yoga classes she can attend, you divide 15 by the amount a yoga class costs, $4.50
15/4.50=3 1/3
Because she can not have 1/3 of a yoga class, she can attend 3 yoga classes in her budget.

what is this one i cant seem to figure it out
Answer:
73
Step-by-step explanation:
Since DA is the diameter, this means that you can divide the circle into two half-circles. You will solve with the right half-circle. A half-circle has a 180 total degrees. Add up the values given and solve for x.
(2x) + (7x - 4) + (85) = 180
2x + 7x - 4 + 85 = 180
9x - 4 + 85 = 180
9x + 81 = 180
9x = 99
x = 11
Now that you have the value of x, solve for m∠CZB.
m∠CZB = 7x - 4
m∠CZB = 7(11) - 4
m∠CZB = 77 - 4
m∠CZB = 73

A 5 hour conference booking is required fir an office party for 120 people which includes a buffet dinner hotel 5 has recently increased the Total chargers by 10% how much would thia Booking now cost from hotel 5
Answer:
Total cost = $4,873
Therefore, the booking cost of hotel 5 would be $4,873
Step-by-step explanation:
Please refer to the attached table.
The total cost includes the cost of the room and the cost of buffet dinner.
From the given table hotel 5,
The cost of the room for 120 people is found to be $166 per hour.
The conference will last for 5 hours so the total cost of the room is
Cost of room = 5*$166 = $830
From the given table hotel 5,
The cost of the buffet dinner per head is found to be $30.
Since there are total 120 people so the total cost of dinner is
Cost of dinner = 120*$30 = $3600
Total cost = $830 + $3600 = $4430
We are given that hotel 5 has recently increased the total chargers by 10%
Total cost = $4430*1.10
Total cost = $4,873
Therefore, the booking cost of hotel 5 would be $4,873.

if sin theta = 2/3 which is possible
Answer:
C. cos theta = √5/3 and tan theta = 2/√5D. sec theta = 3/√5 and tan theta = 2/√5Step-by-step explanation:
According to SOH in SOH, CAH TOA;
SOH means sin theta = opposite/hypotenuse = 2/3
This shows that opposite = 2 and hypotenuse = 3. Before we can determine which of the expression is possible, we need to find the third side of the rigt angled triangle which is the adjacent.
According to Pythagoras theorem; hyp² = opp²+adj²
adj² = hyp² - opp²
adj² = 3² - 2²
adj² = 9 - 4
adj² = 5
adj = √5
Hence the adjacent side is √5.
From the trigonometry identity above;
cos theta = adj/hyp = √5/3 and tan theta = opp/adj = 2/√5
Since sec theta = 1/cos theta then sec theta = 1/(adj/hyp)
sec theta = hyp/adj = 3/√5
From the above calculation, the following are possible:
cos theta = √5/3, tan theta = 2/√5 and sec theta = 3/√5
The correct options are C and D

-7(5-3x)=-35 what is the x in the problem
Answer:
x = 0
Step-by-step explanation:
-7(5-3x)=-35
Divide by -7
-7/-7(5-3x)=-35/-7
5 -3x = 5
Subtract 5 from each side
5-3x-5 = 5-5
-3x=0
Divide by -3
x=0
Answer: x = 0
Step-by-step explanation: Start by distributing the -7 through the parenthses on the left side of the equation.
-7(5) is -35 and -7(-3x) is 21x.
So we have -35 + 21x = -35.
Next, isolate the x term by adding 35 to both sides.
When we do this, we get 21x = 0.
Now divide both sides by 21 and x = 0.

9/140 of NASA shuttle missions were carried out by Challenger.
17/70 of NASA shuttle missions were carried out by Endeavour.
Step-by-step explanation:
Adding the number of missions carried out by NASA gives us 140 in total.
Discovery's total amount of missions simplified is 19/70.
Challenger's total amount of missions is already in the simplest form.
Endeavour's total amount of missions simplified is 17/70.
Answer:
81/140
Step-by-step explanation:
Well to find the fraction we first need to total amount of NASA missions.
38 + 32 = 70
70 + 34 = 104
104 + 27 = 131
131 + 9 = 140
Now we need to find out the amount of Discovery, Challenger, and Endeavour missions.
38 + 9 + 34 = 81
Now we can make the following fraction,
81/140
This is already in simplest form.
Thus,
the answer is 81/140.
