Answer:
a=9/100 b= 7/20
Step-by-step explanation:
For a all you do is take the 9 out of the 100 in 1.
For b, all you do is take the 35/100, and then simplify it, so in this case it is 7/10 if you divide both the numerator and denominator by 5.
So a = 9/100 and b = 7/20

what is an equation that passes through -1,2 and is parallel to the point 3x+y=3 ?
Answers
Answer:
y=3x+5
Step-by-step explanation:
For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel, both slopes are equivalent.
First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:
y-(2)=3(x+1)
y-2=3x+3
y=3x+5
Check:
(2)=3(-1)+5
2=-3+5
2=2

Answers
Answer:
<ABD = 44
<DBC = 44
<ABC = 88
Step-by-step explanation:
If an angle bisects another, then the two resulting angles are equal
In this case <ABC is bisected by BD
which means that
<ABD = <DBC
so
6x + 14 = 3x + 29
simplify and solve using inverse operations
6x + 14 = 3x + 29
-3x -14 -3x -14
3x = 15
/3 /3
x = 5
now substitute into the given values
< ABD = 6x + 14
= 5 * 6 + 14
= 30 + 14
= 44
<DBC = 3x + 29
= 5 * 3 + 29
= 15 + 29
= 44
< ABC = <ABD + <DBC
<ABC = 44 + 44
= 88

Nicole bought 6 tickets to an indoor water park. She paid a 6% service charge for buying them online. Her total cost was
$165.36
a What equation can be used to model the total cost of the tickets?
6. What was the price of each ticket?
C. How much did Nicole pay in service charges?
Answers
Answer:
Step-by-step explanation:
Let each ticket cost x
Answer for Part A
6x + 6% (6x) = 165.36 dollars.
Answer for Part B
6x + 6/100 * 6x = 165.36
6x + 36/100 x = 165.36
6x + 0.36 x = 165.36
6.36x = 165.36
x = 165.36/6.36
x = 26 dollars for each ticket.
Part C
Service charge = 165.36 - 6*26
Service charge = 165.36 - 156
Service charge = 9.36

The slope of the line shown in the graph is

.
Step-by-step explanation:
on edge 2020
The slope of linear Equation is -2.
what is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y= -2x+ 7
Now, we know the standard form of slope- intercept form
y= mx+ b
where m is slope and b is the y- intercept
Now, Comparing it with given equation we get
slope, m= -2

The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; "5" /"8" of them are seventh graders and "3" /"8" of them are eighth graders. If "4" /"5" of the seventh graders participated in track-and-field day and "7" /"8" of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answers
Given that, the total number of students in seventh and eighth grade combined is 584.
The number of students in seventh grade= 5/8 of the total number of students.
[tex]=\frac 5 8 \times 584=365[/tex]
As 4/5 of the total seventh-grade students participated in the track-and-field-event.
So, the number of seventh-grade students participated
[tex]= \frac 4 5 \times 365=292[/tex]
The number of students in the eighth grade 3/8 of the total number of students.
[tex]=\frac 3 8 \times 584=219[/tex]
As 7/8 of the total eighth-grade students participated in the track-and-field-event.
So, the number of seventh-grade students participated
[tex]= \frac78 \times 219=191.625.[/tex]
The number of students must be a counting number, but here, as per the given information, the number of seventh-grade students participated coming out a fractional number, so the given information is incorrect.
Although, as per the given data, the mathematical value of the total number of students participated from both the grade combined
=292+191.625
=483.625 (mathematically)
Again, in real life, the fractional value of the total number of students is not possible.

In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 51°F and the low temperature for the same day was 45°F, what is the number of heating degree days? A. 17 B. 48 C. 113 D. 14
Answers
Given that,
The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
Solution,
The high temperature was 51°F and the low temperature was 45°F.
Average of high and low temperatures for the day is given by :
[tex]T=\dfrac{51+45}{2}\\\\T=48^{\circ} F[/tex]
Now using formula :
H = 65 - T
H = 65 - 48
H = 17
Hence, there are 17 heating degree days.
For which value of x is the function 2x^2 + 3x + 1/x - 1 g(x) undefined?

The function is true [tex]\forall x \in\mathbb{R}[/tex] except 0, because division by zero is undefined.
