Which of the following ratios does NOT represent a proportional relationship?
ANSWER
D 3/4 = 8/6
EXPLANATION
For the ratios to be proportional, the fraction on the left hand side must be equivalent to the one on the right hand side.
So, for each of them, we will check if the values are the same.
a) 3/4 = 6/8
Simplifying 6/8 by dividing numerator and denominator by 2 yields:
3/4 = 3/4
The ratio is proportional.
b) 3/6 = 4/8
Simplifying both sides yields:
1/2 = 1/2
The ratio is proportional.
c) 4/3 = 8/6
Simplifying 8/6 by dividing numerator and denominator by 2 yields:
4/3 = 4/3
The ratio is proportional.
d) 3/4 = 8/6
Simplifying 8/6 by dividing numerator and denominator by 2 yields:
3/4 = 4/3
Because the two fractions are not equal, the ratio is not proportional.
The answer is D.
Angles A and B are supplementary angles. If m
Answer:
138 degrees
Explanation:
Two angles are said to be Supplementary if they add up to 180 degrees.
Given that Angles A and B are supplementary and:
[tex]\begin{gathered} m\angle A=(2x-24)^0 \\ m\angle B=(5x-27)^0 \end{gathered}[/tex]Therefore:
[tex]\begin{gathered} m\angle A+m\angle B=180^0 \\ 2x-24+5x-27=180 \\ 7x=180+27+24 \\ 7x=231 \\ x=\frac{231}{7} \\ x=33^0 \end{gathered}[/tex]Therefore, the measure of angle B will be:
[tex]\begin{gathered} m\angle B=(5x-27)^0 \\ =5(33)-27 \\ =165^0-27^0 \\ =138^0 \end{gathered}[/tex]The measure of angle B is 138 degrees.

10. The value of the 8th term is 78.The sequence is increasing by 10 at each step.Explicit equation: y = 10x - 2Recursive: now = previous term + 10Find the 9th term.Explanation:
We have the explicit equatiion:
[tex]\text{ y = 10x - 2}[/tex]The 8th term is 78
y = 10 * 8 - 2
y = 80 - 2
We replaced x by 8
Therefore, for finding the 9th term, we calculate the value this way:
y = 10 * 9 - 2
y = 90 - 2
y = 88
The 9th term of the series is 88
The question: Rounded to the nearest integer, what is the approximate surface area of this right triangular prism with an equilateral triangle for a base? I just need help solve it because I’m confused
Okay, here we have this:
Considering the provided figure, we are going to calculate the requested surface area, so we obtain the following:
Then we will substitute in the following formula:
Surface Area of Triangular Prism=(√3a^2)/2+3(a+h)
Replacing:
Surface Area of Triangular Prism=(√3*8^2)/2+3(8+6)
Surface Area of Triangular Prism=(√3*64)/2+3(14)
Surface Area of Triangular Prism=(√3*64)/2+42
Surface Area of Triangular Prism=(√3*32)+42
Surface Area of Triangular Prism=32√3+42
Surface Area of Triangular Prism=97 ft^2
Finally we obtain that the aproximately surface area is 97 ft^2.

She spent a total of $21 dollars.
The soda cost $3
Then, she bought 7 candy bars for x dollars
We set x because we don't know the price
3 + 7x = 21
Solve the equation for x
Subtract both sides by 3
3-3 + 7x = 21 -3
7x = 18

A microwave is placed on top of two boxes. One box is 3 feet 5 inches tall, the other box is 2 feet 8 inches tall, and the microwave is 3 feet 10 inches tall. How tall are they combined? Write your answer in feet and inches. Use a number less than 12 for inches.
The combined length is 9 feet 11 inches
What is length?
Distance is measured by length. Length is a quantity having the dimension distance in the International System of Quantities. Most measuring systems use a base unit for length from which all other units are derived. The metre is the basic unit of length in the International System of Units (SI). The greatest extended dimension of a stationary item is typically believed to be its length. This is not always the case, as it may depend on the location of the item. Height, sometimes known as vertical length or vertical extent, and width, breadth, or depth are all words used to describe the length of a stationary object. When length is the greatest dimension, width or breadth generally relate to a lesser dimension.
Given, length of a box = 3 feet 5 inches
length of another box = 2 feet 8 inches
length of microwave = 3 feet 10 inches
Total length = 3 feet 5 inches + 2 feet 8 inches + 3 feet 10 inches
= 9 feet 11 inches

Sam ran 63,756 feet in 70 minutes. What is Sam's rate in
miles per hour? (There are 5,280 feet in one mile.)
Step 1: What is Sam's rate as stated?
The Sam's rate is 10.35 miles per hours.
What is miles per hour?
In mathematics, miles per hour is the unit for the speed measurement. It is used for the calculation of the speed of the train or people or any another objects. It can be calculated by dividing the distance with time.
According to the question, the given data states that the Sam ran 63,756 feet in 70 minutes.
Distance = 63,756 feet and Time = 70 minutes
And the given conversion is: 5280 feet = 1 miles
Therefore, Sam's rate or speed in miles per hour is as written below:
Speed = Distance/Time
Speed = (63,756/70) x (1/5280) x 60 = 10.35 miles per hours
Hence, the Sam's rate is 10.35 miles per hours.

Using equivalent angles, the correct options are given as follows:
cos(-25°) = cos(25º).sin(-136º) = -sin(44º).tan(-212º) = -tan(32º).cot(-315º) = cot(45º).Cos(-25º)Negative 25 degrees is on the fourth quadrant, with the positive angle measure being given by:
360 - 25 = 335º.
The equivalent angle on the first quadrant is of 360º - 335º = 25º, and the cosine on the first quadrant is positive, just like in the fourth, hence:
cos(-25°) = cos(25º).
Sin(-136º)The positive angle measure is given as follows:
360 - 136 = 224º.
Which is on the third quadrant, in which both the sine and the cosine are negative.
The equivalent angle on the first quadrant is given as follows:
224º - 180º = 44º.
Hence the expression is:
sin(-136º) = -sin(44º).
Tan(-212º)The positive angle measure is given as follows:

It is given that there are two quantities 978cm and 12 m.

It is known that 1m=100cm
So 12m=1200cm.
Since 1200>978 so it follows
1200cm>978cm.
so 12m>978cm.
Hence 12 meters is greater than 978cm.
