9 kg of washing powder cost $10.80. What is the cost of 1 kg of washing powder?
Answer:
cost of 1 kg of washing powder is $1.2
Step-by-step explanation:
9 kg = $10.80
cost for 1 kg =
10.80 ÷ 9$1.2Answer:
1.2
Step-by-step explanation:
How I would calculate it would be 10.80 divided by 9 or start timesing 1 with a decimal like 1.1 or 1.2.
but anyway 10.80 divided by 9=1.2 and if you just want to make sure then what is 1.2 x 9 it = 10.80
Here is my calculations for what is 1.20 x 9
1 . 20
9
_________
10 . 8 0
Since there is no didget beside the 2 you would add a zero
since 9 x 2=18 you add a 1 for 1 x 9 =9 + 1=10 and there's your answer.
Answer=1.2
Hope this helps have a great day:)
Sean and Glen share a 16 ounce box of cereal. By the end of the week, Sean has eaten 5/8 of the box,glen has eaten 1/4 of the box of cereal. How many ounces are left in the box?
Answer:
2 ounces are left
Step-by-step explanation:
Sean =
[tex] \frac{5}{8} \times 16[/tex]
= 10 ounces
Gien =
[tex] \frac{1}{4} \times 16[/tex]
= 4 ounces
Sean + gien = 10 + 4 = 14 ounces
so therefore the remaining portion
= 16 - 14 = 2 ounces of cereal is left

Answer:
3/14
Step-by-step explanation:
Put the number of students that want to be a therapist AND have a fear of height (this would be 3) over the TOTAL amount of students in the sample, in this case it's 14.
so it's 3/14 and it doesn't simplify
you're welcome
Answer:
21%
Step-by-step explanation:
First we need to find the total amount of people that did the personality test. We can do that by adding all the numbers in the table
[tex]4+5+2+3=14\\[/tex]
now, to find the percentage of students that want to be a therapist and a fear of heights, we simply divide the number of students who fit that demographic by the total number of students
[tex]3/14= 0.214[/tex]
therefore, there is a 21% chance of picking a student in that demographic at random

A grain silo is composed of a cylinder and a hemisphere. the diameter is 4.4 meters. the height of its cylindrical portion is 6.2 meters. a half-sphere is stacked on top of a cylinder. they both share a circular base. the cylinder has a height of 6.2 meters and the sphere has a diameter of 4.4 meters. what is the approximate total volume of the silo? use 3.14 for π and round the answer to the nearest tenth of a cubic meter. 37.1 m3 71.9 m3 116.5 m3 130.8 m3
The total volume of the silo is 116.6 m³.
What is a grain silo in this problem?It is a solid where a hemisphere is kept on top of a cylinder sharing common circular bases.
Diameter of the cylinder of the silo= 4.4m
So, the radius r of the cylinder will be = 2.2m
The radius r of hemisphere = 2.2m (same as cylinder due to common circular bases)
Height h of the cylinder = 6.2m
The total volume of the silo will be the combined volume of the cylinder and hemisphere.
The volume of cylinder = [tex]\pi r^{2} h[/tex]
The volume of hemisphere = [tex]\frac{2}{3} \pi r^{3}[/tex]
Total volume = [tex]\pi r^{2} h+ \frac{2}{3} \pi r^{3}[/tex]
total volume = [tex]\pi r^{2} (h+\frac{2}{3} r)[/tex]
Total volume = [tex]\pi *2.2^{2} (6.2+\frac{2}{3} *2.2)[/tex]
Total volume = 116.6 m³.
Therefore, the total volume of the silo is 116.6 m³.

Step-by-step explanation:
A set is "closed" under a particular operation if performing that operation on members of the set always results in a member of the set.
Adding two polynomials always results in a polynomial, so we can say "polynomials are closed under addition."

An ammonia and water mixture fills a five-gallon container. Eighty percent of the mixture is ammonia but some of the mixture will be drained and replaced with pure water. If a five-gallon mixture of fifty percent ammonia is desired, how many quarts of the mixture need to be drained before the water is added
Answer:
The volume of the 80% ammonia that is to be drained before water is added is 7.5 quartz
Step-by-step explanation:
The volume of the ammonia and water mixture = 5 gallons
The percentage of ammonia in the mixture = 80%
The volume of ammonia desired = 5 gallons
The percentage concentration of ammonia desired = 50%
The diluting solution = Pure water
The measure of 4 quarts = 1 gallon
Therefore, we have, by equivalence solutions;
80% × x gallon = 50% × 5 gallons
x gallon = 50% × 5 gallons/(80%) = 3.125 gallons
x = 3.125 gallons
The volume of the 80% ammonia that is to be drained = 5 gallons - 3.125 gallons = 1.875 gallons
4 quarts = 1 gallon
1 gallon = 4 quarts
∴ 1.875 gallons = 4 × 1.875 quartz = 7.5 quartz
The volume of the 80% ammonia that is to be drained before water is added = 7.5 quartz
if secx+cosecy = 2, and sinx+cosy=k evaluate 3k/4.
Need help ASAP!
The equations secx+cosecy = 2, and sinx+cosy=k are trigonometry equations
The result of [tex]\frac {3k}4[/tex] is [tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]
How to evaluate 3k/4The equations are given as:
secx+cosecy = 2, and sinx+cosy=k
Divide both equations
[tex]\frac{\sin(x) + \cos(y)}{\sec(x) + \csc(y)} = \frac k2[/tex]
Divide through by 2
[tex]\frac{\sin(x) + \cos(y)}{2[\sec(x) + \csc(y)]} = \frac k4[/tex]
Express sec and cosec as inverse ratios
[tex]\frac{\sin(x) + \cos(y)}{2[1/\cos(x) + 1/\sin(y)]} = \frac k4[/tex]
Take the LCM
[tex]\frac{\sin(y)\cos(x)[\sin(x) + \cos(y)]}{2[\cos(x) + \sin(y)]} = \frac k4[/tex]
Expand
[tex]\frac{\sin(y)\cos(x)\sin(x) + \sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]} = \frac k4[/tex]
Multiply through by 3
[tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]} = \frac {3k}4[/tex]
Rewrite as:
[tex]\frac {3k}4 =\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]
Hence, the result of [tex]\frac {3k}4[/tex] is [tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]

How is ordering factions on a number line similar and different from ordering whole numbers on a number line
Answer:
Fractions and whole numbers ordered on the number line are similar because it tells parts throughout the line, like skip counting using adding or subtraction for example.
What's different from them is because the fractions tell the parts more detailed between the whole numbers, such as 2 3/4 as a fraction on the number line. And 3 as a whole number on the number line.

boxes of Snickers one
week. In total, how many
boxes of candy bars did
they sell?
Answer:
We add the two fractions:
6 3/8 + 7 2/5 = 13 31/40 boxes of candy bars.
Answer:
Add the two fractions 6 3/8 + 7 2/5 = 13 31/40
Step-by-step explanation:
First multiply the whole numbers by the denominator then add it to the numerator, then find the most common factor (in the denominators) which is 40 (8x5 and 5x8) and multiply the numerator by the same number as the denominator, you will get 255/40 and 296/40 add them then simplify then you will get 13 31/40, thank you.

Step-by-step explanation:
Note: " (6)(6)(6) " ; is the value of the
[number "6" ; multiplied by that same number, "6" —two additional times;
→ so the same number, "6" ; being multiplied: "3 (three) times'
= 6 * 6 * 6 = 6³ ; that is: the number "6", raised to the third power (as an exponent);
→ since: there are 3 (three) of the same numbers being multiplied;
⇒ hence the exponent, "3" .
