Answer:
The selling price is $17.40
Step-by-step explanation:
x = selling price
x = 12 + 0.45(12)
x = 12 + 5.4
x = 17.4
The final selling price is $17.40.
Percentages are percents of a whole. This means that 45% = 0.45. You can use this to your advangage when solving these types of equations.
Answer:
$17.40
Step-by-step explanation
Find what 45% of 12 is.
You can do this by multiplying 0.45 by 12 which is 5.4
Then you just add 5.4 to 12 which gives you 17.4

At 109°F, a certain insect chirps at a rate of 77 times per minute, and at 117°F, they chirp 101 times per
minute. Write an equation in slope-intercept form that represents the situation.
The equation that represents this situation is
Answer:
y=3x-250
Step-by-step explanation:
Slope intercept form: y=mx+b
Step 1) to find slope, use (y2-y1)/(x2-x1)
(101-77)/(117-109) = 3
m = 3
Step 2) determine y-intercept (b)
109 * 3 = 327
77-327 = -250
b=-250
y=3x-250
A graphical device for depicting categorical data that have been summarized in a frequency distribution, relative frequency distribution, or percent frequency distribution is a:
The graphical device that divides data according to the percentage they represent is a pie-chart.
Frequency distribution, relative frequency distribution, or percent frequency distribution all are statistical measures that want to establish the part of the distribution corresponding to each measure, that is, percentages, thus they are represented by pie-charts.
An example, suppose that among 50 people sampled, 20 prefer the NBA and 30 the NFL.
Thus, 60% of the sample prefers the NFL, and 40% the NBA.This information is well represented by the pie-chart sketched at the end of this answer.A similar problem is given at https://brainly.com/question/14354536
-12+x=8 properties of equality
Answer:
x=20
Step-by-step explanation:
-12+x=8
Add 12 on both sides (-12 + 12 + x = 8 + 12)
which crosses out -12
and then you get x=20
Rosa says she can break this array into 3 different sets of two smaller arrays . Is Rosa correct ? Explain . The array is a 6 by 8.
Answer:
yes
Step-by-step explanation:
because 6X8=48 and 48 dived by 3 equals 16
Arrays are dataset that are represented in rows and columns. Rosa's claim is correct.
What is an array?An array is a linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations.
From the question, we have:
6 rows and 8 columns
The number (n) of elements in the array is: n = Rows × Columns.
So, we have: n = 6 × 8 =48
Express as sum of three numbers, that is n=12+16+20
Express each term as a product, that is n=2 × 6 + 4 × 4 + 4 × 5
The above expression means that, the array can be split to:
An array of 2 by 6
An array of 4 by 4
An array of 5 by 4
Hence, Rosa is correct.

The Equation of line u is y =-8/9x+5/4. The equation of line v is y =9/8x+7/4. Are line u and line v parallel or perpendicular?
Answer:
when two lines are parallel the two slopes are equal (m1 =m2)
when two lines are perpendicular the product of the slopes is equal to -1( m1m2= -1)
m1 =1st slope
m2= 2nd slope
using the formula y= mx +c
m1= -8/9
m2= 9/8
since m1 is not equal to m2 and -8/9 × 9/8 = -1
It is perpendicular

Answer:

Step-by-step explanation:
ST
3*-2 + 4*-4 = -22 3*0 + 4*5 = 20
-1*-2 + -2*-4 = 10 -1*0 + -2*5 = -10
try TS by yourself
the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].
Given that,
[tex]S=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex] and [tex]T=\left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]
What is the product of two matrix?The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.
Now, [tex]ST=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right] \times \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]
[tex]ST=\left[\begin{array}{cc}(-6-16)&(0+20)\\(2+8)&(0-10)\end{array}\right][/tex]
[tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex]
[tex]TS= \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right]\times \left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex]
[tex]TS=\left[\begin{array}{cc}(-6-0)&(-8-0)\\(-12-5)&(-16-10)\end{array}\right][/tex]
[tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex]
Therefore, the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].

Ronald wanted an allowance. his father gave him a choice of getting it on a weekly or on a daily basis. He said he would either pay him $1.25 a week or pay him in the following manner for a week: On Monday he would give him $0.01; On Tuesday $0.02; On Wednesday $0.04 and on through Sunday. What would you tell Ronald to do so he can get more allowance?
Step-by-step explanation:
Well the addition of ($0.01+$0.02+$0.04) would be $0.07
And he since he can get $1.25 a week if he chose the weekly option
Since $1.25>$0.07
I would tell Ronald to choose the weekly option for getting more allowance.
