The second question:
Consider the division expression [tex]7\frac{1}{2} / 2[/tex]. Select all multiplication equations that correspond to this division expression.
[tex]2 * ? = 7\frac{1}{2}[/tex] [tex]7\frac{1}{2} * ?= 2[/tex] [tex]? * 2 = 7\frac{1}{2}[/tex]
[tex]2* 7\frac{1}{2} = ?[/tex] [tex]? * 7\frac{1}{2} = 2[/tex]
Answer:
1. See Explanation
2. [tex]2 * ? = 7\frac{1}{2}[/tex] and [tex]? * 2 = 7\frac{1}{2}[/tex]
Step-by-step explanation:
Solving (a):
Given
[tex]Students = 60[/tex]
[tex]Group = Equal\ Sized[/tex]
Required
Interpret [tex]\frac{60}{5}[/tex] in 2 ways
Interpretation 1: Number of groups if there are 5 students in each
Interpretation 2: Number of students in each group if there are 5 groups
Solving the quotient
[tex]Quotient = \frac{60}{5}[/tex]
[tex]Quotient = 12[/tex]
For Interpretation 1:
The quotient means: 12 groups
For Interpretation 2:
The quotient means: 12 students
Solving (b):
Given
[tex]7\frac{1}{2} / 2[/tex]
Required
Select all equivalent multiplication equations
Let ? be the quotient of t [tex]7\frac{1}{2} / 2[/tex]
So, we have:
[tex]7\frac{1}{2}/2 = ?[/tex]
Multiply through by 2
[tex]2 * 7\frac{1}{2}/2 = ? * 2[/tex]
[tex]7\frac{1}{2} = ? * 2[/tex]
Rewrite as:
[tex]? * 2 = 7\frac{1}{2}[/tex] --- This is 1 equivalent expression
Apply commutative law of addition:
[tex]2 * ? = 7\frac{1}{2}[/tex] --- This is another equivalent expression
The first term of an arithmetic sequence is 12. The 9th term is -20. What is the common
difference of the arithmetic sequence?
Answer:
-4
Step-by-step explanation:
The formula of an arithmetic sequence is nth term=a+(n-1)d. First term is a and common difference is d.
Let's plug our info in.
-20=12+(9-1)d
-20=12+8d
Subtract 12 from both sides.
-32=8d
Divide both sides by 8.
d=-4

Answer:
we get [tex]Sin X=\frac{12}{13}[/tex]
Option B is correct answer.
Step-by-step explanation:
We need to find the trigonometric ratio Sin X
We know that [tex]Sin X = \frac{Perpendicular}{Hypotenuse}[/tex]
Looking at the figure, we have:
Perpendicular = XY = 24
Base = YZ = 10
Hypotenuse = XZ = 26
Now putting values in the formula and finding value of Sin X
[tex]Sin X = \frac{Perpendicular}{Hypotenuse}\\Sin X =\frac{24}{26}\\Sin X =\frac{12}{13}[/tex]
So, we get [tex]Sin X=\frac{12}{13}[/tex]
Option B is correct answer.

Answer: Choice D) 7.5 inches, 18 inches, 19.5 inches
====================================================
Explanation:
The Pythagorean theorem converse can be used to determine if we have a right triangle or not.
The converse says that if a^2 + b^2 = c^2 is a true equation, then we have a right triangle.
The value of c is always the longest side. The order of 'a' and b doesn't matter (usually b is larger than or equal to 'a'). So we could have [tex]a \le b < c[/tex] or [tex]b \le a < c[/tex], but convention usually leans toward the first inequality mentioned.
----------------------------------
In choice A, we have the following steps
a^2 + b^2 = c^2
(7.5)^2 + (18)^2 = (21.5)^2
380.25 = 462.25
Since the third equation is false, this means the first equation is false for those a,b,c values. Choice A is not a right triangle. We can cross it off the list.
----------------------------------
In choice B, we have a = 7.5, b = 19.5 and c = 21.5
So,
a^2 + b^2 = c^2
(7.5)^2 + (19.5)^2 = (21.5)^2
436.5 = 462.25
which is also false. Cross choice B off the list.
-----------------------------------
With choice C we have: a = 18, b = 19.5, c = 21.5
a^2 + b^2 = c^2
(18)^2 + (19.5)^2 = (21.5)^2
704.25 = 462.25
Cross choice C off the list since the third equation is false.
-------------------------------------
In choice D, we have the sides a = 7.5, b = 18, c = 19.5
a^2 + b^2 = c^2
(7.5)^2 + (18)^2 = (19.5)^2
380.25 = 380.25
We get the same number on both sides, so the third equation is true. Consequently, this leads to the first equation being true for those a,b,c values. Choice D is a right triangle, and it's the final answer.

How can you determine the equation of a line in y =mx + b form from its graph?
Answer:
I'm gonna go a little out of order.
To determine b, find where the line crosses the y-axis. If it's positive, put it as " + " and if it's negative, put it as " - ".
To determine m, find two points on the line that are directly on the number. Example, choose (4, 1) instead of (4.1, 5.2). Go up/down and left/right (while making sure to count) until you reach the second number. going up and right will be considered positive while down and left are considered negative.
Using rise/run, put your number for up/down as a numerator over your left/right, which will be a denominator.
Insert m and b and you're good to go!

There were 41 tickets sold for an event. Tickets for children cost $1.50 and
tickets for adults cost $2.00. Total receipts for the event were $73.50. How
many of each type of ticket were sold?
Answer:
17 kids 24 adult
Step-by-step explanation:
17+24 = 41
17x1.5=25.5
24x2=48
48+25.5=73.5
For the event , 24 adults and 17 children tickets were sold .
Let :
Number of children ticket = cNumber of adult tickets= aNow we have the equations :
a + c = 41 ____(1)2a + 1.5c = 73.5 ___(2)from (1):
a = 41 - c ___(3substitute (3) into (2)
2(41-c) + 1.5c = 73.5
82 - 2c + 1.5c = 73.5
-0.5c = -8.5
c = 17
From (3)
a = 41 - 17
a = 24
Hence, 24 adults and 17 children tickets were sold .

Evan borrowed money from his mom. If he paid her back 9.60 which is 20% of the total he owns, then how much did he owe her to begin with
Given:
Evan paid his mom back 9.60 which is 20% of the total he owns.
To find:
How much did he owe her to begin with.
Solution:
Let x be the amount Evan owns.
According to the question,
20% of x = 9.60
[tex]\dfrac{20}{100}x=9.60[/tex]
[tex]\dfrac{1}{5}x=9.60[/tex]
Multiply both sides by 5.
[tex]x=48[/tex]
Therefore, Evan owns 48 from his mom.

3(x + 2)=x + 11 what is the answer ?
Answer:
x=2.5
Step-by-step explanation:
3(x + 2)=x + 11
3x + 6=x + 11
2x + 6=11
2x=5
x=2.5
Answer:
x=2.5
Step-by-step explanation:
3(x+2)=x+11 (distribute 3 to x&2)
3x+6=x+11 (then you subtract x from both sides)
2x+6=11 (subtract 6 from both sides)
2x=5 ( divide by 2 on both sides)
x= 2.5

Step-by-step explanation:
Here, we want to find the value of x
We use the principle of similar triangles here
We have these as;
(x + 2)/6 = x/4
4(x + 2) = 6x
4x + 8 = 6x
6x - 4x = 8
2x = 8
x = 8/2
x = 4
We proceed to get w;
3+w/6 = 3/4
4(3 + w) = 6(3)
12 + 4w = 18
4w = 18-12
4w = 6
w = 6/4
w = 1.5
