Answer:
a) 4.75g + 5.15c
b) $83.40
Step-by-step explanation:
Gasoline = $4.75 per gallon
Oil = $5.15 per can
Let g = number of gallons
Let c = number of cans
a) Total spend = 4.75g + 5.15c
b) Given:
g = 7.8c = 9⇒ total spend = 4.75(7.8) + 5.15(9)
= 37.05 + 46.35
= $83.40
Increase 128 in a ratio 4:5
Answer:
160
Step-by-step explanation:
5/4 × 128 = 160
__
You can write the proportion ...
128 : x = 4 : 5
Then multiplying by 5x gives ...
(128)(5) = 4x
x = (5/4)(128) = 160 . . . . divide by 4 and evaluate

Find the length of BC. Round your answer to the nearest whole number.
Answer:
------------------
Step-by-step explanation:
----------------------
Answer:
BC = 5 cm (nearest whole number)
Step-by-step explanation:
Use the sine trig ratio:
[tex]\mathsf{\sin \theta=\dfrac{opposite\ side}{hypotenuse}}[/tex]
Given:
[tex]\theta[/tex] = 22.6°side opposite the angle = ahypotenuse = 13Substituting these values into the sine ratio formula:
[tex]\implies \mathsf{\sin (22.6)=\dfrac{a}{13}}[/tex]
[tex]\implies \mathsf{a=13\sin (22.6)}[/tex]
[tex]\implies \mathsf{a=4.995839195...}[/tex]
Therefore, BC = 5 cm (nearest whole number)

The correlation coefficient is -0.12 and the line of the best fit is y = -0.11x + 385.50
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
From the table, the value of r:
r = -0.12
The negative correlation exist between year and time.
Since the value of r is not near the -1 or -1 we can say the relation is very weak.
The line of best fit:
y = mx + c
m = -0.11
c = 385.50
y = -0.11x + 385.50
Thus, the correlation coefficient is -0.12 and the line of the best fit is y = -0.11x + 385.50

The graph below describes the journey of a train between two cities.
a) Work out the
acceleration, in km/h?,
in the first 15 mins.
b) Work out the distance
between the two cities. $60
Velocity (in km/h)
c) Work out the average
speed of the train during 20
the journey.
Answer:
[A] Acceleration in first 15 min = 200 km/h²
[B] Distance between two cities = 125 km
[C] Average Speed of journey = 62.5 km/hr
Step-by-step explanation:
To Solve:
Acceleration in first 15 min
Distance between two cities
Average speed of journey
Solve:
[A] Work out the acceleration, in km/h?, in the first 15 mins.
Each horizontal block is 1/8 hr = 7.5 min
Each vertical block is 10 km/hr
Time Velocity km/hr
0 Min ( 0 hr) 0
15 Min (1/4 hr) 50
45 Min (3/4 hr) 50
60 MIn ( 1 hr) 100
90 Min ( 3/2 hr) 100
120 Min ( 2hr) 0
Acceleration in first 15 min (1/4 hr) = (50 - 0)/(1/4 - 0) = 50/(1/4)
= 200 km/h²
Hence, Answer for [A] = 200 km/h²
[B] Work out the distance between the two cities. $60 Velocity (in km/h)
= (1/2)(0 + 50)(1/4 - 0) + 50 * (3/4 - 1/4) + (1/2)(50 + 100)(1 - 3/4) + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)
= 25/4 + 25 + 75/4 + 50 + 25
= 125
Distance between two cities = 125 km
[C] Work out the average speed of the train during 20 the journey.
Average Speed of journey = 125/2 = 62.5 km/hr

Katrina works as an agent for "Let's Go Air". She averages fifteen passengers every twenty minutes. Stefon also works for the airline and averages fifteen passengers every twenty-five minutes. If Kathrina and Stefon work together, about how many minutes will it take to process fifteen passengers?
The equation computed shows that the number of minutes that it will take to process fifteen passengers is 11.11 minutes.
How to solve the equationSince Katrina averages fifteen passengers every twenty minutes and Stefon also works for the airline and averages fifteen passengers every twenty-five minutes, this can be represented this:
1/x = 1/20 + 1/25
1/x = 9/100
9x = 100
Divide through by 9
x = 100/9
x = 11.11 minutes

The y-intercept of g(x)=3/5f(5x) is 15.
Which of the following is the y-intercept of f(x) ?
A/ 3
B/9
C/25
D/75
Answer:
C) 25
Step-by-step explanation:
A function is scaled vertically by multiplying every function value by the scale factor. For some scale factor k, the function g(x) = k·f(x) is a vertically scaled version of the function f(x).
Here, we are given ...
g(x) = 3/5·f(x)
This means the y-intercept is also scaled:
g(0) = 3/5·f(0)
f(0) = 5/3·g(0) . . . . . multiply by 5/3
f(0) = 5/3·15 = 25
The y-intercept of f(x) is 25.

Please help :( On the coordinate grid shown below, pentagon J is similar to pentagon K.
Which sequence of transformations could be applied to pentagon J to create pentagon K?
A. a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right
B. a reflection across the x-axis, then a translation 2 units up and 8 units right
C. a rotation 90° clockwise about the origin, then a translation 1 unit down and 5 units right
D. a reflection across the y-axis, then a translation 4 units right
Answer:
A. a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right
The sequence of transformation is "a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right" option (A) is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
The missing figure is attached to the picture, please refer to the picture.
From the figure we can see the transformation applied on the pentagon is a 90° counterclockwise rotation around the origin, followed by a translation of Three units up and seven right
Thus, the sequence of transformation is "a rotation 90° counterclockwise about the origin, then a translation 3 units up and 7 units right" option (A) is correct.

Roslyn is an engineer. She is designing a part for a new engine. The length of the part is 16 centimeters (cm), the width is 6 cm, and the height of the cone top is 5 cm, as shown.
What is the volume?
The volume of the shape shown is 105π cm³
What is volume?
Volume is the amount of space occupied by a three dimensional shape and object.
Volume of the cone = (1/3) * π * (6/2)² * 5 = 15π cm³
Volume of the cylinder = π * (6/2)² * (16 - 5 - 6/2) = 72π cm³
Volume of the hemisphere = (2/3)π * (6/2)³ = 18π cm³
Volume of the shape = 15π cm³ + 72π cm³ + 18π cm³ = 105π cm³
