A circular running track is 1/4mile long. Elena runs on this track, completing each lap in 1/20of an hour.
What is Elena’s running speed? Include the unit of measure.
Answer:
5 miles/hour
Step-by-step explanation:
the distance is the length of the track which is given as 1/4 of a mile. she completes each lap in 1/20 of an hour so divide the distance by the time taken to go around the distance
Answer:
Elena's speed is 5 miles/hour
Step-by-step explanation:
The speed is defined as the covered distance per unit time. The distance covered is the length of the circular track which is given as of a mile. We also know that she completes each lap in of an hour. To get her speed, we have divide the distance covered by the time taken to cover this distance and you come out with 5. She can run 5 miles each hour. Or in other words you take 20 divided by 4 you get 5
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

Find the slope of the line y=1 over 6 x + 3 over 2
Answer:
1/6x
Step-by-step explanation:
the slope intercept form is: y = mx + b
m = slope
b = y-intercept.
When you already have in the form the slope is where m is, so the number that's is with x. In this case it's 1/6x.
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;

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

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

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.

the value of x in 2x-7=5
Answer:
x = 6
Step-by-step explanation:
2x - 7 = 5
=> 2x = 5 + 7
=> 2x = 12
=> x = 12 / 2
=> x = 6
Hope it helps :)
Answer:
x = 6
Step-by-step explanation:
2x - 7 = 5
→ Add 5 to both sides
2x = 12
→ Divide both sides by 2 to isolate x
x = 6
In what ways are the line of reflection and the line of symmetry the same?
Answer:
A shape has reflection symmetry if there exists a line of reflection that carries the shape onto itself. This line of reflection is called a line of symmetry. In other words, if you can reflect a shape across a line and the shape looks like it never moved, it has reflection symmetry.

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.
