Which equation represents this sentence
“Mark is five years older than Jeffrey. The sum of Mark’s age and triple Jeffrey’s age is 73”
Answer:
C
Step-by-step explanation:
Let m represent Mark's age and j represent Jeffrey's age.
Mark is five years older than Jeffrey. Hence:
[tex]m=j+5[/tex]
The sum of Mark's age and triple Jeffrey's age is 73. In other words:
[tex]m+3j=73[/tex]
We can substitute:
[tex](j+5)+3j=73[/tex]
Therefore, our answer is C.

Ted can clear a football field of debris in 3 hours. Jacob can clear the same field in 2 hours. When they work together, the situation can be modeled by the equation, where t is the number of hours it would take to clear the field together.
How long will it take Ted and Jacob to clear the field together?
Answer:
[tex]\frac{6}{5}[/tex] of an hour = 1 1/5 hour = 72 minutes
Step-by-step explanation:
[tex]\frac{1}{3} h + \frac{1}{2}h = 1\\\\\frac{2}{6} h + \frac{3}{6}h = 1\\\\\\\frac{5 }{6} h =1\\\\h=\frac{6}{5}[/tex]
It would take Ted and Jacob 6/5 or 1.2 hours to clear the field together.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Let's use the formula for the work rate:
Ted's work rate = 1/3 of the field per hour
Jacob's work rate = 1/2 of the field per hour
Together, their work rate.
= (1/3 + 1/2) of the field per hour
Now,
We can simplify the equation for the combined work rate by finding a common denominator:
(1/3 + 1/2)
= (2/6 + 3/6)
= 5/6 of the field per hour
Now we can use the formula for the work rate to solve the time it would take them to clear the field together:
(5/6)t = 1
(where t is the time in hours)
Solving for t:
(5/6)t = 1
t = 6/5
Therefore,
It would take Ted and Jacob 6/5 or 1.2 hours to clear the field together.

a parallelogram has side lenghts 20 cm and 25 cm. the diagonal opposite the obtuse angle measures 38 cm. what is the measure of the obtuse angle?
Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
9514 1404 393
Answer:
114.8°
Step-by-step explanation:
The angles can be found using the Law of Cosines. It tells you ...
c² = a² +b² -2ab·cos(C)
Then angle C can be found to be ...
C = arccos((a² +b² -c²)/(2ab)) = arccos((20² +25² -38²)/(2·20·25))
C = arccos(-419/1000) ≈ 114.77°
The measure of the obtuse angle is about 114.8°.

A daycare center operator wanted to survey her parents to determine if they were interested in the center providing once-a-month Saturday night care for their children. Rather than survey all 254 parents, the operator took the list of parents' names and, starting with the third parent's name, surveyed every twelfth parent. What type of sampling did the daycare operator use
Answer:
Systematic Sampling
Step-by-step explanation:
According to the Question,
systematic sampling is a statistical method involving the selection of elements from an ordered sampling frame. The most common form of systematic sampling is an equiprobability method. In this approach, progression through the list is treated circularly, with a return to the top once the end of the list is passed. The sampling starts by selecting an element from the list at random and then every Kth element in the frame is selected.So, systematic sampling is right Answer.

the total number of paintings depend upon the number of weeks that have passed as she adds 3 paintings every week to her collection.
1. can't be an option as output values depend upon the input values and hence not independent
4. can't be an option because each week that passes she adds 3 more paintings and since one input has 3 outputs, its not a function.
5. the number of weeks is the input value and number of paintings is the output value as you can later SEE how many paintings she has, not how many weeks it took her.
Answer:
(B, C, D)
Step-by-step explanation:
This scenario can be represented using this equation:
y = 3x + 7
y = total paintings after # of weeks (dependent variable)
x = # of weeks (independent variable)
3 = 3 paintings per week
7 = initial number of paintings
Let's evaluate each answer choice:
"The independent variable is represented by the ouput values"
No, this is wrong. The indepedent variable is the input values.
"The dependent variable is the total number of paintings"
This is correct. The total # of paintings is the output value, or the dependent variable.
"The total number of paintings depends on the number of weeks that have passed"
This is correct. The total # of paintings is the output value, or the dependent variable, because it depends on the # of weeks that pass by.
"This scenario is a function because for each week that passes, there will be exactly one total number of paintings"
This is correct. There is only one possible output for each input.
"The number of weeks is the output value"
No, this is wrong. The total # of paintings is the output value, not the # of weeks.

Answer:
0.4
Step-by-step explanation:
consider this like some lines overlapping each other.
one line (A) is 0.5 long, the other (B) 0.4 long.
together they are 0.8 long.
that means that they overlap at a length of 0.1 (they share a segment 0.1 long).
of the combined line of 0.8 that has 0.1 of a joined segment, the complimentary part of B is therefore 0.4 (0.8 minus the original length of B).

The functionſ is defined by f(x) = x(x + 3). If f(a) = 40 and a > 0, what is the value of a ?
A) 3
B) 5
C) 7
D) 8
Answer:
B) 5
Step-by-step explanation:
We are given the function:
[tex]f(x)=x(x+3)[/tex]
We are given that f(a) = 40 and a > 0 and we want to determine the value of a.
Substitute:
[tex]f(a)=40=a(a+3)[/tex]
Distribute:
[tex]a^2+3a=40[/tex]
Subtract 40 from both sides:
[tex]a^2+3a-40=0[/tex]
We can factor using 8 and -5. Hence:
[tex](a+8)(a-5)=0[/tex]
By the Zero Product Property:
[tex]a+8=0\text{ or } a-5=0[/tex]
Solve for each case:
[tex]\displaystyle a=-8\text{ or } a=5[/tex]
Since a > 0, we can eliminate the first solution. Hence:

7x-49=y
Solve for x?
The solution for x is x = (y + 49)/7.
Given that an equation 7x - 49 = y, we need to determine the equation in for of x,
To solve for x in the equation 7x - 49 = y, we'll isolate x on one side of the equation.
Here's the step-by-step process:
Start with the given equation: 7x - 49 = y.
Add 49 to both sides of the equation to isolate the term with x:
7x = y + 49.
Divide both sides of the equation by 7 to solve for x:
(7x)/7 = (y + 49)/7.
Simplify:
x = (y + 49)/7.
Therefore, the solution for x is x = (y + 49)/7.
