What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
Some of the coordinates from the graph are:
(1, 18), (2, 36), and (3, 54)
Now,
The rate of change between (1, 18), and (2, 36).
Slope = (36 - 18) / (2 - 1) = 18
The rate of change between (2, 36), and (3, 54).
Slope = (54 - 36) / (3 - 2) = 18
This means,
That for every hour there is an earning of $18.
Thus,
The graph shows that for every hour the earnings are $!8.

Answer:
XZ = 16.25 cm
QR = 6.8 cm
Step-by-step explanation:
A) Taking the proportion of similar sides
=> [tex]\frac{7.2}{6.5} = \frac{18}{XZ}[/tex]
Cross Multiplying
=> 7.2 XZ = 18*6.5
=> XZ = 117/7.2
=> XZ = 16.25 cm
B) Taking proportion of similar sides
=> [tex]\frac{18}{17}=\frac{7.2}{QR}[/tex]
Cross Multiplying
=> 18 QR = 17*7.2
=> QR = 122.4/18
=> QR = 6.8 cm

Answer: 35 / 66
Step-by-step explanation:
Given the data bekow:
Outcome : - - - 1 - - - 2 - - - 3 - - - 4 - - - 5 - - - 6
Frequency : - 12 - - - 9 - - - 11 - - 8 - - - 12 - - - 14
What is the experimental probability of spinning an odd
P(spinning an odd) = (number of occurrence of an event / number of trials)
Odd outcomes = 1, 3, 5
Frequency of 1 = 12
Frequency of 3 = 11
Frequency of 5 = 12
Number of occurrences of odd = (12 + 11 + 12) = 35
Number of trials = 66
Therefore,
P(spinning an odd) = 35 / 66
In a half-kilo jar of legumes there are 2.5g of fat. In another 400g can of legumes B there is 2.1g of fat. Are these data in proportion? If the data is not in proportion, in which of the two cans is there more fat proportionally?
Answer:
no400 g canStep-by-step explanation:
A half-kilo jar is 500 grams, so a 400 g can would be 4/5 the weight. 4/5 of 2.5 g of fat would be 2.0 g of fat. The 400 g can has 2.1 g, so has more fat, proportionally, than its weight would suggest.
The fat is not proportional to the can sized. The 400 g can has more fat, proportionally.

Mercury and Alcohol are two common liquids used in thermometers. The boiling point of MERCURY is 357 degree C, while its freezing point is -39 degree C; For ALCOHOL, the boiling point is 78 degree C and the freezing point is -80 degree C; It is required in a laboratory to make measurements which are in the region of -60 degree C. Which type of thermometer would be more suitable? (ASSET)
Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.

A cylindrical container with a radius of 6 cm and a height of 10 cm is filled with water to a depth of 6 cm. A sphere with a radius of 3 cm is placed at the bottom of the container.
a) What is the volume of the water to the nearest tenth?
b) What is the volume of the sphere to the nearest tenth?
c) How much higher does the water level rise in the container, to the nearest tenth, after the
sphere is placed inside?
Answer:
a. 452.4 cm³ to the nearest tenth b. 113.1 cm³ to the nearest tenth
c. 5.0 cm to the nearest tenth
Step-by-step explanation:
a. The volume of the water V₁ = πr²h since it is in a cylindrical container. r = 6 cm and h = 10 cm - 6 cm = 4 cm (since it is filled to a depth of 6 cm measuring from the top, so we have a height from the bottom of 10 cm - 6 cm = 4 cm).
So, V₁ = πr²h
= π × (6 cm)² × 4 cm
= 452.39 cm³
= 452.4 cm³ to the nearest tenth
b. The volume of the sphere V₂ = 4πr³/3 where r = radius of sphere = 3 cm.
V₂ = 4πr³/3
= 4π(3 cm)³/3
= 113.1 cm³ to the nearest tenth
c. When the sphere is placed in the container, the new volume of water in the container would be V = V₁ + V₂
So V = 452.4 cm³ + 113.1 cm³ = 565.5 cm³
Since the volume of water is still the volume of a cylinder, its height h is
h = V/πr²
= 565.5 cm³/π(6 cm)²
= 5.0 cm to the nearest tenth

The volume of a right-rectangular prism is 15 cubic feet. The prism is 2½ feet wide and has a height of ½ foot. How long, in feet, is the rectangular prism?
Answer:
12 feet
Step-by-step explanation:
To get the volume of a rectangular prism, you must multiply the height, width, and length of the prism. So to get your answer, you must multiply 2 1/2 and 1/2, then divide 15 feet by the answer. 2 1/2 × 1/2 × 12 = 15
A trapezoid has an area of 20 cm2 and a height z cm. The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm. Find the height, z, of the trapezoid. In your final answer, include all of the formulas and calculations necessary.
Answer: 2.11cm
Step-by-step explanation:
Given the following :
The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm
The area of trapezoid is calculated using the formula:
1/2(a + b) × h
Where ;
a = Length of side 1
b = length of side 2
h = height
Take a = (2z + 3) and b = (6z – 1), h = z
Therefore ;
1/2 (2z + 3 + 6z - 1) × z
Opening the bracket
(z + 1.5 + 3z - 0.5) × z
(4z + 1 ) × z = 20cm^2
4z^2 + z = 20cm^2
Using Quadratic formula:
4z^2 + z - 20 = 0
a = 4, b = 1, c = - 20
(-b±√b^2 -4ac) / 2a
Z = 2.11 or - 2.364
z cannot be negative, therefore,
Z = 2.11 cm
