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.

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
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.
Write the equation for the line passing through points (0, 0),(4, 5), and (8, 10).
Answer:
y=5/4x
Step-by-step explanation:
The equation for the line passing through points (0, 0),(4, 5), and (8, 10) is; y = (5/4)x
From the coordinate, (0, 0), we can conclude that the y-intercept of the line is 0.
In essence, to determine the equation of the line, we must evaluate the slope by consider two points on the line namely;
(4, 5), and (8, 10).Slope, m = (y2 -y1)/(x2 - x1).
Slope, m =( 10 - 5)/(8-4)
m = 5/4.Therefore, the equation of the line is;
y = (5/4)x.Read more on equation of a line;

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

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

He measures and determines that he needs 24 feet of fencing. When he arrives at home improvement store, he realized fencing is priced at $0.25 per inch how much will it cost to fence it
Answer:
It will cost 72 dollars to fence the perimeter
Step-by-step explanation:
First of all, we will have to make sure that we are working with the same units.
To do this, we will have to convert our units which are given in feet to inches.
1 foot = 12 inches
24 feet = 288 inches.
We now have the total length of what he needs to be 288 inches.
The fence costs 0.25 dollars per inch.
Therefore 288 inches will cost 0.25 X 288 = $ 72

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm? 3.14 d less-than 50 3.14 d greater-than 50 50 d greater-than 3.14 50 d less-than 3.14
Answer:
3.14 d greater-than 50
(i also need help with one of my questions >~<)
Step-by-step explanation:
Since the circumference of a circle is approximately 3.14 times the length of its diameter, mathematically speaking:
C = 3.14d
That expression must be greater (>) than 50:
3.14 d > 50
So, the correct option is; 3.14 d greater-than 50
