what is the quotient of 3/20 of 10 is divided by 5/10 of 6/14?
Answer:
30
Step-by-step explanation:
6/10 of 20 is 12
7/14 of 12/15 is 1/2 of 4/5 which is 2/5
so you have to compute 12 ÷ 2/5 which is done as 12 times (5/2) which is 30.

M-1/4=3/4 need to find m plz help
Answer:
M=1
Step-by-step explanation:
m-1/4=3/4 add 1/4 to both sides and you get m=1
Answer:
M = 1
Step-by-step explanation:
M-1/4=3/4
add 1/4 to both sides of the equation:
M - 1/4 + 1/4 = 3/4 + 1/4
simplify:
M = 1

What is the hypotenuse of a triangle with legs that are both 4 inches?
By applying Pythagorean's theorem, the hypotenuse of this triangle is equal to: D. √32 inches..
Given the following data:
Adjacent side = 4 inches
Opposite side = 4 inches.
How to calculate the hypotenuse of a triangle?In order to calculate the hypotenuse of this triangle, we would apply Pythagorean theorem.
Mathematically, Pythagorean's theorem is given by this formula:
c² = a² + b²
Where:
c is the hypotenuse.a is the adjacent side.b is the opposite side.Substituting the given parameters into the formula, we have;
c² = 4² + 4²
c² = 16 + 16
c² = 32
c = √32 inches.

Sue has $100 saved to buy concert tickets that go on sale in 8 weeks. She plans to save $15 every 2 weeks. Will Sue have enough money saved to buy 4 concert tickets that cost $50 each?
Answer:
she wont have enough money.
Step-by-step explanation:
she is saving money every 2 weeks. 8 divided by 2 is 4, so we'd have 15 x 4 which is 60. then we'd add it to 100, which would be 160, then divide it by 4, which would roughly come down to 40 dollars each, meaning we would not have enough money for 4 tickets
Answer:
she does not have enough she will need 40 dollars more

The diameters of bolts produced in a machine shop are normally distributed with a mean of 6.4 millimeters and a standard deviation of 0.06 millimeters. Find the two diameters that separate the top 5% and the bottom 5%. These diameters could serve as limits used to identify which bolts should be rejected. Round your answer to the nearest hundredth, if necessary.
Answer:
The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.
Step-by-step explanation:
We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.
Let us find the sample score that corresponds to z-score of bottom 4%.
From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.
Upon substituting these values in z-score formula we will get our sample scores (x) as:
Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.
Now let us find sample score corresponding to z-score of 1.75 as upper limit.
Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected
Answer:
6.30 millimeters and 6.50 millimeters.

0.2) Sharad bought one quintal of onions for Rs 2000. Later he
sold them all at the rate of Rs 18 per kg. Did he make a profit
or incur a loss? How much was it?
Answer: Loss, 200 Rs
Step-by-step explanation:
Given
Sharad bought a quintal of onion i.e. [tex]1000\ kg[/tex] for [tex]Rs.\ 2000[/tex]
So, the cost price of onion is
[tex]\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}[/tex]
He sells it at [tex]18\ \text{Rs. per kg}[/tex]
Here, the Selling price is less than the cost price
So, he incurs a loss of [tex]2\ \text{Rs per kg}[/tex]
For a quintal it is
[tex]\Rightarrow 2\times 100=200\ \text{Rs}[/tex]
[tex]\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%[/tex]
If the product of two integers is zero, then which of the following MUST be true?
A) Both of the Integers are zero
B) At least one of the integers is zero
C) The sum of the two integers is zero
D) The difference of the two integers is zero
Answer:
B
Step-by-step explanation:
Anything times zero is zero, so any whole number can be the second one so long as the first is 0.
The sum doesnt have to equal zero because non zero numbers multiplied by zero still equal zero.
Which represents the value of c?
Answer:
Step-by-step explanation:
you are given the law of sines, in the question, so i'm guessing you don't get "law of sines" ???
some times I think people might just be lazy and they don't try, but I can understand if you really don't get "law of sines' b/c it is kinda abstract.
Any way here is how you solve this problem and please ask if you don't understand about something I do to solve this. Ask about it if you don't get it. :)
Sin(45) / c = Sin(45) / 3
now algebraically solve for c
3* Sin(45) / Sin(45) = c
if you're thinking the answer is 3 you're right.
indecently , if you didn't notice, this is an isosceles triangle and they do have the same length legs. so you know that x = 3 right away from that, but, it's good to understand Law of Sines as well. :)

Garrett has a current checking account balance of $695. Over the next three days, he receives a direct deposit of $475.75 from his job, pays an annual online banking fee of $24, and makes purchases of $34.21 and $8.92. He then withdraws $60 from an ATM that charges a $3.50 usage fee.
What is Garrett's account balance at the end of the day period? Write your answer in numeric form, such as $1369.05.
Answer:
1040.12
Step-by-step explanation:

Maria decides to increase her homework time of 8 hours per week by 15% Calculate her new homework time. Give your answer in hours and minutes
Answer:
Maria's homework time is now 9 hours 12 minutes.
Step-by-step explanation:
Since Maria decides to increase her homework time by 15%.
Then,
15% of 8 hours = [tex]\frac{15}{100}[/tex] x 8 hours
= 0.15 x 8 hours
= 1.2 hours
(Note that: 1.2 hours = 1 hour 12 minutes)
15% of 8 hours = 1 hour 12 minutes
her new homework time = 8 hours + 1 hour 12 minutes
= 9 hours 12 minutes
Maria's homework time is now 9 hours 12 minutes.
