Step-by-step explanation:
ok lets imagine if the variables were x and y
the equation would be as follows
y=3x+2
y=-1/3x+7
The answer will be an ordered pair, (x,y) because that specifies exactly where on graph, instead of a general location which you would get if you only had the x or only had the y
Answer:
1y2x

what is the answer of this question?
9514 1404 393
Answer:
970
Step-by-step explanation:
It turns out that the radical terms cancel, so the result is an integer. You can find the integer value using your calculator. It is ...
(5 +2√6)³ +1/(5 +2√6)³ = 970
_____
The cube of 'a' is ...
(5+2√6)³ = 5³ +3·5²·2√6 +3·5·(2√6)² +(2√6)³
= 125 +3·50√6 +3·120 +48√6
a³ = 485 +198√6
The reciprocal of this is ...
b³ = 1/a³ = 1/(485 +198√6) = (485 -198√6)/(485² -6·198²) = (485 -198√6)/1
b³ = 485 -198√6
Then the sum is ...
a³ +b³ = (485 +198√6) +(485 -198√6) = 970

A rectangle has a perimeter of 56 cm and an area of 96cm^2. Its length is 4 more than five times its width. What is the lenght and width of the rectangle?
Answer:
L= 24cm
W= 4cm
Step-by-step explanation:
Given data
Perimeter= 56cm
Area= 96cm^2
Let the width be x
W= x cm
L= 5x+4
P=2L+2W
56= 2(5x+4)+2x
56= 10x+8+2x
56-8= 12x
48= 12x
x= 48/12
x= 4cm
L= 5x+4
L= 5(4)+4
L= 20+4
L= 24cm

If Gavin has 6 9/20th of time left to play videos, what is that mixed number written in minutes and seconds?
Answer:
[tex]387\ \text{minutes}[/tex]
Step-by-step explanation:
The time Gavin has is [tex]6\dfrac{9}{20}\ \text{hours}[/tex]
[tex]6\dfrac{9}{20}=\dfrac{20\times 6+9}{20}[/tex]
[tex]=\dfrac{129}{20}\ \text{hours}[/tex]
[tex]=6.45\ \text{hours}[/tex]
[tex]=6\times 60+0.45\times 60=360+27[/tex]
[tex]=387\ \text{minutes}[/tex]
The number of minutes is [tex]387\ \text{minutes}[/tex].

What is the value of x?
Enter your answer in the box.
x =
Answer:
x = 98 degrees
Step-by-step explanation:
A heptagon has a total of 900 degrees for the interior angles. Add up all the angles and then subtract from 900 to find x.
146+122+142+140+110+142 = 802.
900-802 = 98
Answer:
x = 98
Step-by-step explanation:
This shape has 7 sides. Using the formula n - 2 we can get the number of triangles. n represents the number of sides.
n - 2 = 5
All triangles have 180 degrees, so multiply 180 by the number of triangles (5).
180 × 5 = 900
The total number of degrees in this shape is 900. Adding the other angle measures and then subtracting them from 900 gives us x.
146 + 122 + 142 + 140 + 110 + 142 = 802
900 - 802 = 98.
x = 98
A farmer sells 8.4 kilograms of pears and apple at the market. 1/4 of this weight is pears and the rest is apples. How much kilograms of apples did she sell at the market
Answer:
[tex]Weight = 6.3 kg[/tex]
Step-by-step explanation:
Given
[tex]Total = 8.4kg[/tex]
[tex]Pears = \frac{1}{4}[/tex]
Required
Determine the weight of apples
First, we calculate the fraction of apple.
[tex]Apple = 1 - Pears[/tex]
[tex]Apple = 1 - \frac{1}{4}[/tex]
Take LCM
[tex]Apple = \frac{4-1}{4}[/tex]
[tex]Apple = \frac{3}{4}[/tex]
The weight is then calculated as:
[tex]Weight = \frac{3}{4} * Total[/tex]
[tex]Weight = \frac{3}{4} * 8.4kg[/tex]
[tex]Weight = \frac{3* 8.4kg}{4}[/tex]
[tex]Weight = \frac{25.2kg}{4}[/tex]
[tex]Weight = 6.3 kg[/tex]
Hence, the apples weigh 6.4kg

Is there a linear relationship between height and volume? Explain how you know.
Answer:
Yes
Step-by-step explanation:
The volume is for example the area of a circle times the height. If you divide the volume of a cylinder by the amount the radius is squared multiplied by pi, to calculate its height.
Yes, there exists a linear relationship between the height and the volume.
What is a linear relationship?A linear relationship is a relationship between the variables in a linear fashion. The relations ships can positive, negative, and neutral. Volume is a scalar quantity that is expressed in three-dimensional space.
Example of volume for the area of a circle is times the height. If we divide the volume of a cylinder by the amount of R it can be squared and multiplied by pi, to find its height.
Find out more information about the volume.

Yani is creating a mural on a patio that measures 3 m long by 2 m wide. He is using 1 cm by 1 cm tiles. How many tiles will he need to use for the mural to cover the whole patio?
Answer: 60,000 tiles
Step-by-step explanation:
First find the area of the mural.
= 3 * 2
= 6 m²
The find the area of the tiles.
= 1 * 1
= 1 cm²
I m² = 10,000 cm²
There is therefore:
= 6 * 10,000
= 60,000 cm²
That is the area that needs to be covered in cm²
Seeing as each tile is 1cm², the number of tiles needed is:
= 60,000 / 1
= 60,000 tiles
Answer: the answer is 60,000 tiles
by the way that kinda seems like a lot of tiles to place like how long is that gonna take.
