Express the ratio in lowest form:
1.5 kg: 350 g
Given:
The ratio is:
1.5 kg : 350 g
To find:
The lowest or simplest form of the given ratio.
Solution:
We know that,
1 kg = 1000 g
We have,
1.5 kg : 350 g
It can be written as
[tex]1.5\ kg : 350\ g=\dfrac{1.5\ kg}{350\ g}[/tex]
[tex]1.5\ kg : 350\ g=\dfrac{1.5\times 1000\ g}{350\ g}[/tex]
[tex]1.5\ kg : 350\ g=\dfrac{1500\ g}{350\ g}[/tex]
[tex]1.5\ kg : 350\ g=\dfrac{150}{35}[/tex]
[tex]1.5\ kg : 350\ g=\dfrac{30}{7}[/tex]
Therefore, the lowest form of the given ratio is 30:7.

drawing.
Train Car
10.8 cm
What is the actual length of the train car?
A.21.6 ft
B.27 ft
C.43.2 ft
D54 ft
Answer: c
Step-by-step explanation:
The required actual length of the train is given as 27 ft.
Given that,
Heather drew the scaled drawing of a train car shown below. She used the scale of 2 cm = 5 ft to complete the drawing.
The scale factor is defined as the ratio of the modified change in length to the original length.
here,
As given,
2 cm = 5 ft
1 cm = 5/2 ft
Tain car length = 10.8 m
Actual length = 10.8 × 5/2 = 27 ft
Thus, the required actual length of the train is given as 27 ft.

Which 2 variables are most likely to show a negative correlation when represented on a scatter plot?
Answer:
Water level and temperature
Step-by-step explanation:
Scatter plots are used to graph linear data containing to two variables, with the independent variable on the x - axis and the dependent variable on the y-axis. Linear data graphed on a scatter plot may be positive or negative depending on the type of relationship which exists between the two variables. Positive relationships are represented by positive slopes, with x increasing as y increases. Negative relationship on the other hand results in a reduction in Y as X increases and vice versa. Examples of negative correlation include the association between water level and temperature. ; water level will usually decrease as temperature rises. Therefore, any association between variables whereby a increase in one leads to a corresponding decrease on the other is tagged as a negative correlation.

Can someone please help with these 2 questions? It would mean the world to me. I have attached the image for the questions.
Answer:
2 [tex]\frac{1}{20}[/tex]
Step-by-step explanation:
for question a)
It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)
to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.
E.g.
7 [tex]\frac{1}{4}[/tex] = 7x4 + 1 = 29
Thus, improper fraction would be [tex]\frac{29}{4}[/tex]
do same thing for other one
thus , [tex]\frac{26}{5}[/tex]
now,
[tex]\frac{29}{4}[/tex] - [tex]\frac{26}{5}[/tex]
however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)
[tex]\frac{145}{20} -\frac{104}{20}[/tex] = [tex]\frac{41}{20}[/tex]
convert back to mixed number
2 [tex]\frac{1}{20}[/tex]
Answer:
Step-by-step explanation:
a) Step1 : write in improper form
Step 2 : Find least common denominator
Step 3: Find equivalent fractions and then subtract
[tex]7\frac{1}{4}-5\frac{1}{5} = \frac{29}{4}-\frac{26}{5}\\[/tex]
[tex]= \frac{29*5}{4*5}-\frac{26*4}{5*4}\\\\=\frac{145}{20}-\frac{104}{20}\\\\=\frac{145-104}{20}\\\\=\frac{41}{20}\\\\=2\frac{1}{20}[/tex]
b) Keep Change Flip method
[tex]4\frac{1}{4}[/tex] ÷ [tex]2\frac{1}{5} = \frac{17}{4}[/tex] ÷ [tex]\frac{11}{5}[/tex]
[tex]=\frac{17}{4}*\frac{5}{11}\\\\=\frac{85}{44}\\\\=1\frac{41}{44}[/tex]

The volume of a cylinder is 471 cm? If the
height is 6 cm, calculate the radius.
Someone plz help
Answer:
Step-by-step explanation:
Formula for volume of a circle: V=πr²
If you multiply the circle by height, it becomes a cylinder.
Formula for volume of a cylinder: V=πr²h
Plug in the numbers and get r by itself:
471 = πr²(6)
Divide both sides by 6:
78.5 = πr²
Divide both sides by π:
25 = r²
Square root both sides:
[tex]\sqrt{25}[/tex] = [tex]\sqrt{r} \\[/tex]²

(4n+1)(2n+6) multiply polynomials
Answer:
= 8n^2 +26n +6
Step-by-step explanation:
(4n+1)(2n+6)
= 8n^2 + 24n +2n +6
= 8n^2 +26n +6
The product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.
To multiply the polynomials (4n+1)(2n+6), you can use the distributive property.
(4n+1)(2n+6) = 4n x 2n + 4n x 6 + 1 x 2n + 1 x 6
Applying the distributive property and simplifying each term:
= 8n² + 24n + 2n + 6
Combining like terms:
= 8n² + 26n + 6
Therefore, the product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.
