Answer:
190 is the answer of the equation.
Step-by-step explanation:
a(b + c) × 2
Now putting the values of a,b and c.
5(7+12)×2
= 5(19)×2
= 95×2

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

what is 25/176 as a decimal division
Step-by-step explanation:
[tex] \frac{25}{175} [/tex]
[tex]0.142045[/tex]
[tex]0.1420[/tex]
[tex] \frac{14.2}{100} [/tex]

Answer:
0.1420454545
Step-by-step explanation:
If :
100 : 176 = 0.5681818182
so :
[tex]\sf{= \frac{25}{176} }[/tex]
[tex]\sf{= \frac{ 25 \times 0.5681818182}{176 \times 0.5681818182} }[/tex]

Consider the matrices
Show that multiplication of matrices is not commutative be determining the product matrices ST and TS. Enter your answer by filling in the boxes.
Answer:
Answer attached
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].

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

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.

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.
