Add 3 7/12 +2 7/9. Simplify the answer and write as a mixed number.

Answers

Answer 1

3 7/12 = 43/12

2 7/9 = 25/9

both denominators must be the same to add together.

(25/9)x 12

(43/12) x 9

300/108 + 387/108 =

687/108

which in its simplest form is 229/36

and in a mixed number is 6 13/36

Answer 2
find lowest common denominator 9 × 12 = 108
cross multiply 9 ×7 and 12 ×7
3 63/108 + 2 84/108 => 3 147/108 => 4 39/108

Find -5

-5 (not exactly sure what this question is asking)

The correct order from least to greatest is -16, -14, -12, 0, 13, 17. The number farthest to the right on the number line is 1, and 'finding -5' means locating the number -5 on a number line.

The question involves ordering numbers from least to greatest and finding the position of a number on a number line. To order numbers from least to greatest, you look for the smallest or most negative number and move towards the largest or most positive number. When placed on a number line, negative numbers are to the left of zero, and positive numbers are to the right of zero. Therefore, the correct order from least to greatest is -16, -14, -12, 0, 13, 17.

Moreover, the number farthest to the right on a number line from the options given is 1 because it is the greatest number listed and is positioned to the right of all the other numbers.

Finally, to 'find -5', it simply means to locate the number -5 on the number line. It is negative, so it will be to the left of zero.

A parachutist descends 64 feet in 4 seconds. Express the rate of the​ parachutist's change in height as a unit rate.

The unit rate of the parachutist's change in height is __ feet per second.

Answers

To find you answer, divide 64 by 4
Final answer:

To find the unit rate of the parachutist's change in height, we divide the total distance descended (64 feet) by the total time (4 seconds). This yields a unit rate of 16 feet per second.

Explanation:

In order to calculate the unit rate of this parachutist's descent, we need to set up a fraction with the total distance descended over the overall time. In this case, the parachutist descends 64 feet in 4 seconds.

We then solve for the unit rate by dividing the distance descended (64 feet) by the time it took to descend (4 seconds). So, the calculation would be 64 ÷ 4 = 16.

So, the unit rate of the parachutist's change in height is 16 feet per second.

A standard showerhead in Nathan's house dispenses 11 gallons of water per minute. Nathan changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x How much water does Nathan save each day with the change in showerheads if he uses the shower for 8 minutes each day? 8 gallons 24 gallons 33 gallons 64 gallons

Answers

The new shower head dispenses 3 gallons of water per minute, as shown in the equation y = 3x.

So, 3 x 8 = 24.

Then, to find out how much he saves each day, you would find how much he used before,

11 x 8 = 88

Next we want to see how much Nathan saved, so we subtract the total,

88 - 24 = 64

Nathan saved 64 gallons.

Answer: 64 gallons

There are 150 marigold plants in a back yard. Each month, the number of marigold plants decreases by 15%. There are 125 sunflower plants in the back yard. Each month, 8 sunflower plants are removed. Part A: Write functions to represent the number of marigold plants and the number of sunflower plants in the back yard throughout the months. (4 points) Part B: How many marigold plants are in the back yard after 3 months? How many sunflower plants are in the back yard after the same number of months? (2 points) Part C: After approximately how many months is the number of marigold plants and the number of sunflower plants the same? Justify your answer mathematically. (4 points)

Answers

Let us first assign variables. We say that:

X = number of marigold plants

Y = number of sunflower plants

n = number of months

We can see that in the given problem, X is decreasing by a percentage, this means that we have to set-up a geometric equation while for Y the decrease is linear so we set-up an arithmetic equation.

 

Part A.

For marigold plants X, a geometric sequence has a general form of:

X = Xo * (1 + r)^n

where r = -15% = -0.15   (negative since it is decreasing)

Xo = the initial amount of marigold plants = 150

X = 150 * (1 – 0.15)^n

X = 150 (0.85)^n

 

For the sunflower plants Y, an arithmetic sequence has a general form of:

Y = Yo + d * n

where d = -8 and Yo = 125

Y = 125 – 8 n

 

Part B. For n = 3

 

X = 150 (0.85)^3 = 92.12 = 92

 

Y = 125 – 8 (3) = 101

 

Part C. From Part B we see that the two values are very far from each other when n = 3, therefore they must be similar when n < 3. So we try n = 2

 

X = 150 (0.85)^2 = 108.38 = 108

 

Y = 125 – 8 (2) = 109

 

Therefore the two plants have approximately similar amount after 2 months.

 

A student attempted to generate an equivalent expression using the distributive property, as shown below: 4(x + 2) = x + 8 What was the mistake made?

Answers

The distributive property states that a(b+c)=ab+ac.
In this situation, 4(x+2)= 4*x+ 4*2.
While the student multiplied 4*2 to get 8, the student did not multiply 4*x to get 4x.

4(x + 2) = 4(x) + 4(2)
= 4x + 8

mistake that a student forgot to multiply 4 on the first variable and it's supposed to be 4x + 8, not x + 8

What is the smallest value in the stem and leaf plot below?
STEM | LEAVES

3 | 4 4 5 5

Key: 3 | 5 means 35
A:2
B: 20
C: 35
D: 2337

Answers

Listing the data from the Stem and Leaves table as raw data we have:

02, 03, 03, 07, 10, 10, 17, 34, 34, 35, 35

Hence the smallest value is 02 = 2

Answer: A

Final answer:

The smallest value in the provided stem-and-leaf plot is 2, corresponding to the lowest stem of 0 with the lowest leaf of 2.

Explanation:

The student's question is asking for the smallest value displayed in a provided stem-and-leaf plot. The stem-and-leaf plot shows numbers divided into stems (tens place) and leaves (ones place), which tells us unique values in the dataset. In this case,

STEM | LEAVES
0         | 2 3 3 7
1         | 0 0 7
3         | 4 4 5 5

According to the provided key, which states that '3 | 5' means '35', we can see that the smallest stem is '0' and the smallest leaf in the '0' stem row is '2', combining these gives us the smallest value in the plot. Therefore, the smallest value in the stem and leaf plot is 2, which corresponds to option A: 2.

1x - 6 + 1y -18 =16

Which function is undefined when x= pi/2 radians
cos x
cot x
csc x
tan x

Answers

The Cot x is undefined because it is equal to (Sin x)/(Cos x) and at pi/2, Cosine = 0.

Answer:

Option 4 that is tan x will be undefined at x=pi/2 radians

Step-by-step explanation:

[tex]\frac{\pi}{2}radians=90^{\circ}[/tex]

In case 1:

We have cos x

[tex]\text{Cos x has value 0 at x}=\frac{\pi}{2}radians[/tex]

Therefore the function is defined hence, option 1 is discarded.

In case 2:

We have cot x and

[tex]cot x=\frac{cos x}{sin x}[/tex]

Since, [tex]\text{cos x at x}=\frac{\pi}{2}\text{radians is 0}[/tex]

And [tex]\text{sin x at x}=\frac{\pi}{2}\text{radians is 1}[/tex]

Hence,[tex]cot x=\frac{0}{1}=0[/tex]

Hence, defined and Option 2 is discarded.

In case 3:

We have csc x and

[tex]csc x=\frac{1}{sin x}[/tex]

Since, [tex]\text{sin x at x}=\frac{\pi}{2}\text{radians is 1}[/tex]

Hence,[tex]csc x=\frac{1}{1}=1[/tex]

Hence, defined and Option 3 is discarded.

In case 4:

We have tan x and

[tex]tan x=\frac{sin x}{cos x}[/tex]

Since, [tex]\text{cos x at x}=\frac{\pi}{2}\text{radians is 0}[/tex]

And [tex]\text{sin x at x}=\frac{\pi}{2}\text{radians is 1}[/tex]

Hence,[tex]tan x=\frac{1}{0}=\infty[/tex]

Hence, undefined and Option 4 is correct.
