Answer:
Step-by-step explanation:
A landscaping company placed two orders with a nursery. Sam tried to use system of equation to solve the problem.
Let us represent
Cost of bushes = x
Cost of trees = y
The first order was for 13 bushes and 4 trees, and totaled $327.50.
Hence
13x + 4y = 327.5......Equation 1
The second order was for 6 bushes and 2 trees, and totaled $142.96.
Combined both Equations
13x + 4y = 327.5......Equation 1
6x + 2y = 142.96 ........ Equation 2
We solve using Elimination method
We Multiply Equation 1 by 2 and Equation 2 by 4 to Eliminate y
26x + 8y = 655 ..... Equation 3
24x + 8y = 571.84 ..... Equation 4
We substract Equation 4 from Equation 3
2x = 83.16
x = 83.16/2
x = $41.58

Suppose you have two 3 by 3 matrices ,say A and B How can the square of the A and B be mathematically expressed a).AB² b).[AB]² Which one the two is correct?
Answer:
[tex][AB]^2[/tex]
Step-by-step explanation:
Given
Matrices A and B
Required
Represents the square of A and B
The interpretation of the question is that:
The square of the product of A and B
This can be represented as:
The square(product of A and B)
Product means *
So, we have:
The square(A * B)
The square means ^2
So, we have:
[tex][A * B]^2[/tex]
This gives:
[tex][AB]^2[/tex]
Hence, the second option is correct

Step-by-step explanation:
if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
Answer:
m = rise/run = 270/20.5 = 13.17
Step-by-step explanation:
Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is
m = rise/run = 270/20.5 = 13.17

What is the measure of angle 4?
angles 1,3,5,6,7, and 8 are 73 degrees. angles 2 is 107 degrees
Answer:
34 Deg
Step-by-step explanation:
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34
An electronics store buys 200 stylus at a cost of $400 and sells them for $6 each. Find the percent markup rounded to the nearest percent?
Answer:
Percent markup is 200%
Step-by-step explanation:
The cost of each stylus is
[tex]\frac{400}{200} = 2[/tex] dollars
The selling price of each stylus is $6
Percent markup =
(Selling price - cost price)/cost price *100
[tex]\frac{6-2}{2} *100\\2*100\\200[/tex]%
Percent markup is 200%
What are the coordinates of Rx=3(G)?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

a skateboard is on sale for $47.80. if this price represents a 50% discount from the original price, to the nearest cent?
Answer:
95.60$
Step-by-step explanation:
50% discount is basically the price divided by 2. So if we inverse it it will become x2. 47.80x2=95.6

What value of y makes the equation 4x – 3y = 17 true, when x = 2?
Answer:
y = -3
Step-by-step explanation:
4x – 3y = 17
x = 2
4(2) - 3y = 17
8 - 3y = 17
-3y = 9
y = -3
Answer:
y= -3
Step-by-step explanation:
if x =2, substitute
4(2) - 3y = 17
8-3y = 17
(add 3y to both sides)
8= 17 + 3y
(subtract 17 from both sides)
8-17=3y
-9= 3y
(divide both sides by 3)
-9/3=y
y= -3

Answer:
a) [tex]p = 88\,cm[/tex], b) [tex]p = 24\,cm[/tex], c) [tex]p \approx 25.424\,m[/tex], d) [tex]p \approx 39.368\,cm[/tex]
Step-by-step explanation:
a) The perimeter is the sum of the three sides of the internal square and the remaining sides of the external rectangle, that is:
[tex]p = 3\times 8\,cm + 2\times 4\,cm +2\times 20\,cm + 16\,cm[/tex]
[tex]p = 88\,cm[/tex]
b) The perimeter is the sum of the two sides of the internal triangle and the remaining sides of the external rectangle, that is:
[tex]p = 2\times 4\,cm + 2\times 6\,cm + 4\,cm[/tex]
[tex]p = 24\,cm[/tex]
c) The perimeter is the sum of the two sides of the circular section and the three sides of the lower rectangle, that is:
[tex]p = \frac{\pi}{2}\times 6\,cm + 8\,cm + 6\,cm + 2\,cm[/tex]
[tex]p \approx 25.424\,m[/tex]
d) The perimeter is the sum of the external sides of the triangle and rectangle, that is:
[tex]p = 10\,cm + 12\,cm + 12\,cm + 12\,cm - \sqrt{(12\,cm)^{2}-(10\,cm)^{2}}[/tex]
[tex]p \approx 39.368\,cm[/tex]

Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms
r = [tex]\frac{384}{512}[/tex] = [tex]\frac{288}{384}[/tex] = [tex]\frac{216}{288}[/tex] = [tex]\frac{3}{4}[/tex] , then recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex] : a₁ = 512
What is the value of this expression when c=-4 and d = 10?
1/4(c3+d2)
What is the value of this expression when c = -4 and d = 10 ? [tex] \frac{1}{4} [/tex] (c³ + d²)
Answer:-Given:-[tex] \frac{1}{4} [/tex] (c³ + d²) where c = -4 and d = 10
To Find:-The value of the expression [tex] \frac{1}{4} [/tex] (c³ + d²)
Solution:-[tex] \frac{1}{4} [/tex] (c³ + d²) [Given expression]
Now, putting the value of c = -4 and d = 10 , we get,
[tex] \frac{1}{4} [/tex] { (-4)³ + (10)² }
[tex] \frac{1}{4} [/tex] ( -64 + 100 )
[tex] \frac{1}{4} [/tex] ( 36 )

Plus why defuk she need that manny binder clip. Does she eat them
Answer:
6318 / 39 = 162 boxes.
This question does not really make sense because you ask how many boxes are needed, then say that the clips are coming in 39 boxes.
