Choose the mixed number that is equivalent to this decimal 3.242424...
Answer:
3.24 = 3 6/25
Step-by-step explanation:
- Rewrite the decimal number as a fraction with 1 in the denominator.
- Multiply to remove 2 decimal places. Here, you multiply top and bottom by 100
- Find the Greatest Common Factor (GCF) of 324 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4
- You should end up with that answer..
Solve for x.

Answer: 1
Submit Answer
Terms
Answer:
x=-3
Step-by-step explanation:
-2(-x-3)-4x-1=13
2x+6-4x-1=13
-2x+5=13
-2x=8
x=-4
Answer:
x = -4
Step-by-step explanation:
Expand
2x + 6 - 4x - 1 = 13
Rearrange, by collecting like terms and placing them on either side of the equation.
2x - 4x = 13 + 1 - 6
Simplify
-2x = 8
Divide both sides by -2
-2/-2x = 8/-2
x = -4
how do you do trigonometery with 2 angles and a length
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles, with these functions one can answer virtually all questions about.
Answer:
(a/sinA)＝(b/sinB)＝(c/sinC)
Step-by-step explanation:
a and b and c is the length
A,B,Cis angle.
This is a formula.
E.g. the angle opposite of the length a is A.
A master baker can fill a big order in 6 hours. A student baker can fill the same order in 8 hours. They start working together, and after 2 hours, the student leaves and the master baker finishes the work alone. How long will it take him to finish the order?
Answer:
It will take the master baker 2.86 hours to finish the remaining order after 2 hours.
Step-by-step explanation:
the time taken for the master baker to fill the order = 6 hours
the time taken for the student baker to fill the order = 8 hours
let the time taken for both to finish the work together if they work at the same rate = x
[tex]\frac{x}{8} + \frac{x}{6} =1\\\\\frac{3x + 4x}{24} = 1\\\\7x = 24\\\\x = \frac{24}{7}\\\\x = 3.43 \ hours[/tex]
After 2 hours, the remaining time for them to finish the work together is given by;
t(remaining) = 3.43 hours - 2 hours = 1.43 hours
Working at the same rate, 2 persons will take 1.43 hours to finish the remaining work.
One person will take hour many hours ?
2 persons working at the same rate --------> 1.43 hours
1 person working at the same rate -----> ?
= 2 x 1.43 hours
= 2.86 hours
Therefore, it will take the master baker 2.86 hours to finish the remaining order after 2 hours.

Which step did this student do wrong?
Answer:
Step 1
Step-by-step explanation:
When the student first removed the parenthesis by multiply it by 7, he forget to multiply 5 by seven. So instead of x + 3 + 7x - 35, he got what you see on the picture before you.

-35/6=(7/6)x
x=-5
Consider the statement "Worldwide in 2014, there are more than $2.5 trillion in credit card transactions." Make sure that you fill in each answer area before checking "How Did I Do?". What was the daily average dollar amount of transactions? Round to the nearest hundred million dollars. $ Number How many dollars were spent in credit card transactions each day?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
In 2014:
Worth of credit card transaction = $2.5 trillion
The daily average dollar amount of transaction:
Number of days in a year = 365
(Yearly worth of transaction / number of days in a year)
$(2,500,000,000,000) / 365
= $6,849315068.4931
= $6,849, 000,000 (nearest 100 million dollars)
Amount spent in transaction daily :
= $6,849,315,058
Factor this x^3 + 27
One of the largest swimming pools in the world is in Garden City, Kansas. It is rectangular and
measures 67 meters by 100 meters. If you swim diagonally across the pool, how many meters would
you swim? Round your answer to the nearest whole meter
Answer:
The answer is 7,000 meters
Step-by-step explanation:
because you do 67*100 which equals to 6,700 and then u round it which makes it equal to 7,00 meter
Answer:
120 meters (approx)
Step-by-step explanation:
Think of the rectangle like two triangles;
if we find the hypotenuse of one, then we know the length of the rectangle across
Remember the Pythagorean theorem:
a^2 + b^2 = c^2
where a and b are the sides of the triangle
so then substitute in the known values:
a = 100
b = 67
now solve
100^2 + 67^2 = c^2
14489 = c^2
sqrt(14489) = c
120.37 = approx c
