To find the geometric mean of two numbers, start by multiplying them together.
12 * 27 = 324
Now take the square root of that number
√324 = 18
Find the value of x. The diagram is not to scale.
Answer:
x = 33
Step-by-step explanation:
There are 180 degrees in a triangle.
There are also 180 degrees in a straight line.
180 - 105 = 75.
Thus, 75+72+x=180.
x=33
Answer:
x=33
Step-by-step explanation:
Step one :
From the screen shot
The sum of angles on a straight line is 180° hence 180°-105°=75°
The unknown angle is 75°
Step two :
To find the angle x° the sum of angles in a triangle is 180°
Therefore
x°+72°+75°=180°
x+147=180
x=180-147
x=33°

8,000÷(28x+4)−15=25
Answer:
x = 7
Step-by-step explanation:
Order of operations rules require that we do multiplication and division BEFORE addition and subtraction.
Let's start by simplifying the expression. Adding 15 to both sides results in:
8,000÷(28x+4) = 40.
Multiplying both sides by (28x + 4) results in the simpler:
8000 = 40(28x + 4).
Dividing both sides by 40 results in:
200 = 28x + 4, or
196 = 28x
Solve for x by dividing both sides by 28:
x = 7

(x − 5)(x − 5)
(x + 5)(x − 5)
(x − 1)(x + 25)
Prime
Answer:
)x + 5)(x - 5)
Step-by-step explanation:
x² - 25 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
x² - 25 = x² - 5² = (x + 5)(x - 5)
A bag contains 6 red balls, 4 green balls, and 3 blue balls. If we choose a ball, then another ball without putting the first one back in the bag, what is the probability that the first ball will be green and the second will be red?
Answer:
2/13
Step-by-step explanation:
There are 6 + 4 + 3 = 13 balls all together.
If the first one is green, this will happen with a probability of 4/13. Now there are 12 balls left
There are 6 red balls. 6/12 = 1/2
The probability of the way this happens is 1/2 * 4/13 = 2/13
A population of 550 rabbits is increasing by 7.5% each year. In about how many years will the population be over 1000?
A.) 9 years
B.) 5 years
C.)7 years
D.)15 years
Answer:
D.) 15 years
Step-by-step explanation:
7.5% of 550 rabbits would be 41.25
if you are increasing till you get over 1,000
it would take 10.9 almost 11 years to get to 1,000
meaning it would be 15 years when your over 1,000 giving you 1,168.75
how do you locate fraction 4/1 on a number line
Answer:
Move 4 units to the right-hand side of the origin point, 0.
Step-by-step explanation:
A number line in mathematics is a straight line marked with numbers to the left(negative numbers) and to the right (positive numbers), at equal intervals along the line.The origin of the number line is 0. 4/1 is similar to positive 4 which is located 4 units to the right-handside of 0.
To locate the fraction 4/1 on a number line, you need to divide the number line into 1 part and find the 4th part.
Explanation:To locate the fraction 4/1 on a number line, you need to understand that fractions represent a part of a whole. In this case, the fraction 4/1 means that you are dividing the number line into 1 part and looking for the position of the 4th part. Here's how you can do it:
Draw a number line with appropriate markings, such as whole numbers.Divide the number line into equal parts based on the denominator of the fraction. In this case, since the denominator is 1, you don't need to divide further, as every part is the same size.Locate the numerator on the number line. In this case, 4 is equivalent to four parts of the whole number line.Mark the location of 4 on the number line.What is the distance between -13 and 13 on a number line

While taking inventory at her bakery, Ruby noticed that she had 5⁄6 pound of cinnamon yesterday, but now had only 2⁄3 pound. How much more cinnamon did Ruby have yesterday?
Answer:
1/6 of a pound
Step-by-step explanation:
Multiply both the numerator and denominator for a common denominator.
2/3 * 2/2 = 4/6.
Then subtract to find out how much more she had yesterday.
5/6-4/6=1/6.
1/6 pound
Match the denominator
2/3 = 4/6
Subtract
5/6 - 4/6 = 1/6

Solve the inequality 3k > 5k+12
Alright, let's solve this problem! :)
First we need to subtract 5k from both sides.
3k−5k>12
Then we simplify 3k - 5k to -2k.
-2k > 12
Now we divide both sides by -2.
k < -12/2
Now we simplify 12/2 to 6.
k < -6
✔️Done!
Have an amazing day!

The tenth in 149.95 is 9. To round it to the nearest tenth, use the hundredth. The hundredth is 5. When rounding, always round up when it is a 5. 95 should be rounded to 100, but it is a decimal. 100 as a decimal is equal to 1. 149 + 1 = 150.
Answer:
149.95 becomes 150 when rounded to the nearest tenth because 149.95 is only .5 away from 150. If it was something like 149.4 it would be rounded to 149.
Many has 40 ounce of butter that he is cutting into 1.25 ounces . How many slices will he have?
He would have 32 slices of butter.
The student will have 32 slices of butter if they cut 40 ounces into 1.25-ounce pieces by dividing the total amount by the size of each slice.
The student wants to know how many slices of butter they can get from 40 ounces if they are cutting it into 1.25 ounces each. To find out, they need to divide the total amount of butter by the size of each piece.
First, take the total amount of butter, which is 40 ounces.
Divide 40 ounces by the size of each slice, which is 1.25 ounces.
Calculate the division: 40 / 1.25 = 32 slices.
Therefore, the student will have 32 slices of butter if they cut 40 ounces into 1.25-ounce pieces.
Which of the following equations represents a line that is parallel
Answer:
B
Step-by-step explanation:
A parallel line means equal m values, so the slope of the equation has to be 3.
Then, we can plug in the (1,6) to each of the equations with 3 as a slope and see if they are equal to each other.
B. 6 = 3 + 3
B. 6 = 6
So B is the correct equation.

x+2y=6 how do I solve this ?
Answer:
The answer is 4y
Step-by-step explanation:
This is because when you have a variable and 2 numbers you work backwards to find the number of the x so you do the opposite of adding you subtract, 2 - 6 remember you are working backwards but now you have the answer 4 but there is a variable next to the two so you so you add that to the four.
What is the slope of the line show below?
Algebra form: y1 - y2, and x1 - x2.
( 2 - 1 ) ( 6 - 3 ).
= 1/3.
slope = 1/3.

Franco wants to have $750,000 when he retires in a year. If he currently has $700,000 to put in a 1-year CD, which of these APRs and compounding periods will allow him to reach his goal?
Answer:
Francesco can achieve this amount by investing at an APR of 7.14% compounded annually , or 7% compounded every six months or 6.95% compounded quarterly
Step-by-step explanation:
This question can be solved using the concept of compounded interest
The formula for amount obtained when a principal of p was invested at a rate r compounding n times a year is:
[tex]Amt = p(1+\frac{r}{100n})^n[/tex]
Here p = 70000, amt = 75000,
So when compounded annually, n=1
[tex]Amt =p(1+\frac{r}{100n})^n\\75000=70000(1+\frac{r}{100})^1\\\frac{15}{14}=1+\frac{r}{100}\\\frac{1}{14}=\frac{r}{100}\\r = \frac{100}{14}=7.14[/tex]
For compounding every 6 months n=2
[tex]Amt =p(1+\frac{r}{100n})^n75000=70000(1+\frac{r}{200})^2\\\frac{15}{14}=(1+\frac{r}{200})^2\\\sqrt{\frac{15}{14}}=1+\frac{r}{200}\\r = 200*(\sqrt{\frac{15}{14}}-1)=7.01[/tex]
For compounding quarterly n=4
[tex]Amt =p(1+\frac{r}{100n})^n\\75000=70000(1+\frac{r}{400})^4\\\frac{15}{14}=(1+\frac{r}{400})^4\\(\frac{15}{14})^\frac{1}{4}=1+\frac{r}{400}\\r = 6.95[/tex]

Step-by-step explanation:
a farmer grew x pounds of rice last year. This year, she grew 8% more rice than she grew last year. which expression represent the number of pounds of rice that the farmer grew this year?
Answer:108%*x
Step-by-step explanation: 100%+8%=108% so it is 108%*x
Final answer:
The expression representing the amount of rice the farmer grew this year is 1.08x, which includes the initial amount plus an additional 8% increase.
Explanation:
If a farmer grew x pounds of rice last year, and this year she grew 8% more rice than she grew last year, the number of pounds of rice she grew this year can be represented by an algebraic expression. To calculate an increase of 8%, we multiply the original amount (x) by 8% (or 0.08) and then add it to the original amount. The expression representing the total weight of rice grown this year is:
x + 0.08x
Or, combining like terms to simplify:
1.08x
This expression takes into account the original production and adds the additional 8% increase in rice production for this year.
