Answers
9514 1404 393
Answer:
(x, y) = (61/23, 36/23)
Step-by-step explanation:
We assume you intend the equations to be ...
5x -4y = 7x = 5 -3/2yThen in general form, they are ...
5x -4y -7 = 0
2x +3y -10 = 0
The solution using the "cross multiplication method" is ...
1/(15 +8) = x/(40+21) = y/(-14 +50)
(x, y) = (61/23, 36/23)

Comment on "cross multiplication method"
When the coefficients from the general form equations are written as a 2×4 array with the first and last columns the same ...
[tex]\left\{\begin{array}{cccc}5&-4&-7&5\\2&3&-10&2\end{array}\right\}[/tex]
the solution is 1/d1 = x/d2 = y/d3, where d1, d2, d3 are the determinants of successive pairs of columns.
d1 = (5)(3) -(2)(-4)d2 = (-4)(-10) -(3)(-7)d3 = (-7)(2) -(-10)(5)A manufacturing manager reports to the CEO that 5% of products that come off the assembly line are defective.

the $700 you put into the bank is being continuously at 1.2%. how much will it be worth after 3 years?
Answers
Answer:
$983.45
Step-by-step explanation:
Given data
Principal= $700
Rate= 1.2%
Time= 3 years
The compound interest expression is given as
A= P(1+r)^t
A= 700(1+0.12)^3
A= 700(1.12)^3
A= 700*1.404928
A=$983.45
Hence the balance will be $983.45

Richard paid six times as much for his computer as he did for his printer. He paid a total of $1680 for both items. What did each item cost? The printer costs (?)$ and the computer costs (?)$
Answers
Answer:
the computer was 280, and the printer was 6 times that. do the math an you have ur answer
The cost of a printer is $240 and the cost of a computer is $1440.
Given that, the cost of both computer and printer is $1680.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the cost of printer be x.
Richard paid six times as much for his computer as he did for his printer.
Then, the cost of computer will be 6x
Now, 6x+x=1680
⇒ 7x=1680
⇒ x=1680/7
⇒ x=$240
So, 6x=$1440
Therefore, the cost of a printer is $240 and the cost of a computer is $1440.

Carl is filling flowerpots with soil. Each flowerpot is a cylinder with a radius of 7cm and a height of 10 cm. If Carl has 24,000 cubic centimeters of soil, how many flowerpots can he fill? Explain.
Answers
Answer:
see below
Step-by-step explanation: 5 26 9 17
cylinder with a radius of 7cm and a height of 10 cm
find the value of each flower pot and divided it into 24000 cm³
flower pot = π r² h = π × 7² × 10 = π490 = 1539.38 cm³
24000 cm³ / 1539.38 cm³ = 15.59 flower pots
so Carl could only FILL 15 flower pots
Carl is filling flowerpots with soil. Each flowerpot is a cylinder with a radius of 7cm and a height of 10 cm. If Carl has 24,000 cubic centimeters of soil. So, Carl could only fill 15 flower pots.
What is the volume of a right circular cylinder?Suppose that the radius of considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The cylinder with a radius of 7cm and a height of 10 cm.
The flower pot = π r² h
[tex]= \pi \times 7^2 \times h\\ = 490 \pi \\ = 1539.38 cm^3[/tex]
= 24000 cm³ / 1539.38 cm³
= 15.59 flower pots
So, Carl could only fill 15 flower pots.

Find the volume of this cone
Answers
Answer:
[tex]\frac{6400\pi}{3}\approx 6702.06\:\mathrm{cm^3}[/tex]
Step-by-step explanation:
The volume of a cone is given by [tex]V=\frac{1}{3}\cdot r^2\pi\cdot h[/tex].
In this specific cone, the entire height of the cone is not given. However, we do see that it is broken up into two separate cones. Since one cone is inside/part of the other, these cones must be similar. Therefore, we can set up the following proportion to find the height of the smaller cone.
Let [tex]h_s[/tex] be the height of the small cone:
[tex]\frac{5}{h_s}=\frac{20}{12+h_s},\\\\20h_s=5(12+h_s),\\\\20h_s=60+5h_s,\\\\15h_s=60,\\\\h_s=4[/tex]
Therefore, the height of the largest cone is [tex]12+4=16[/tex]. Now we have all necessary information to find the volume of the cone:
[tex]V=\frac{1}{3}\cdot 16\cdot 20^2\cdot \pi =\frac{6400\pi}{3}\approx \boxed{6702.06\:\mathrm{cm^3}}[/tex]
