Solve using a matrix
Answers
Solution of the system of equation 3x + y = 5 , 5x + 2y = 9 using matrix is x =1 and y =2.
As given in the question,
System of equation:
3x + y = 5 ,
5x + 2y = 9
In matrix form :
[tex]\left[\begin{array}{ccc}3&1\\5&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}5\\9\end{array}\right][/tex]
[tex]D = \left[\begin{array}{ccc}3&1\\5&2\end{array}\right][/tex]
= (3)(2) -(5)(1)
=1
[tex]D_{x} = \left[\begin{array}{ccc}5&1\\9&2\end{array}\right][/tex]
= 10 -9
= 1
[tex]D_{y} = \left[\begin{array}{ccc}3&5\\5&9\end{array}\right][/tex]
= 27 -25
= 2
[tex]x= \frac{D_{x}}{D}[/tex]
= 1
[tex]y =\frac{D_{y}}{D}[/tex]
=2
Therefore, solution of the system of equation 3x + y = 5 , 5x + 2y = 9 using matrix is x =1 and y =2.

what is the height of this cone?
Answers
Answer:
height is = 3/2 ft
Step-by-step explanation:
a cones volume can be represented by 1/3(h)(pi)(r^2)
we must go backwards to find this question out
if the diameter is 2/3 then the radius is 1/3
then you must square that
that is 1/3 * 1/3 which is 1/9
1/9(1/3)(pi)(h) is 1/18(pi)
we can remove pi from both sides and multiply the 1/9 and the 1/3
1/27(h) = 1/18
we must find the lcm or least common multiple to figure this out
the lcm is 54
1/27 is essentially 2/54 and 1/18 is 3/54
2/54(h) = 3/54
we can multiply each side by 54
2h = 3
divide 2 on both sides
h is 3/2

Answers
Answer:
2m²

Write the percent as a fraction and decimal:
72%, 25%, 500%, 5%
Answers
Answer:
Decimals:
0.72, 0.25, 5.0, 0.05
Fractions in simplest forms:
18/25, 1/4, 5/1, 1/20
Step-by-step explanation:
To convert percentages into decimals:
You divide the percentage by 100.
To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
To convert a percent to a fraction, we have to remove the percent sign and divide the given number by 100. And, then we express the fractional form of the percentage in the simplest form. For example, 1% is 1/100, 2% is 2/100 which can be reduced to 1/50.

What is the sum of the geometric series, rounded to the nearest whole number? 16 E n-1
6(1/4)^n A=2, B=3, c=4 d=6
What's the correct answer please
Answers
The infinite sum is (first term) divided by (1 minus the common ratio). The first term is 6(1/4) = 3/2; the common ratio is 1/4:
[tex]S=\frac{\frac{3}{2} }{1-\frac{1}{4} } =\frac{\frac{3}{2} }{\frac{3}{4} } =(\frac{3}{2} )*(\frac{4}{3} )=2[/tex]
The terms after n=16 are tiny and will certainly bring the sum down only a tiny bit.
So to the nearest whole number the sum of the finite geometric series is 2.
20 POINTS!! What would be the first step to solve this equation?
m - 13 = 24
A. Subtract 13 from both sides
B. Add 24 to both sides
C. Add 13 to both sides
D. Divide by 13 on both sides
Answers
Answer:
C. Add 13 to both sides of the equation.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:
m - 13 = 24
m - 13 (+13) = 24 (+13)
m = 24 + 13
m = 37

A triangle has an area of 156 square millimeters and a base of 16 millimeters. What is the
height?
Answers
Answer: Height = 19.5mm
Step-by-step explanation:
The area of a triangle is the base*height/2.
We can plug in the values given for the base and area.
Therefore, 156 mm^2 = 16mm*height/2
Multiply both sides by 2:
312 mm^2 = 16mm*height
Divide both sides by 16mm:
Height = 19.5mm

What is the sale price for a beach umbrella with a regular price of $43.59 which is on sale for 20% off?
Answers
Answer:
$34.87
Step-by-step explanation:
20% of $43.59
[tex]\frac{20}{100} X \frac{43.59}{1}[/tex] = [tex]\frac{1}{5} X \frac{43.59}{1}[/tex] = [tex]\frac{43.59}{5}[/tex] = $8.718
Therefore the price is, $43.59 - $8.718 = $34.87
Answer:
The answer is $34.87
Step-by-step explanation:
$43.59- 8.72=$34.87
20% of $43.59 is $8.72
So, your answer will be $34.87
$43.59- 8.72=$34.87
