A student measures the length of her dress to be 60 inches long but the actual length of her dress is 65 inches long. What is the percent error of this student
Answer:
8.333% error
Step-by-step explanation:

(actual - expected) / expected * 100 %
actual = 65
expected = 60
plug
(65-60)/60 * 100%
= 8.33 %
The values of m and n are whole numbers greater than 1. Which is true about the quotient
Answer:
"The expression will always equal m" is true about the quotient of [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
Step-by-step explanation:
Let us solve the question
∵ The expression is [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of [tex]\frac{1}{n}[/tex] is [tex]\frac{n}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex]
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = [tex]\frac{m}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = m
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = m
∴ The quotient is m
∴ The expression will always equal m
anyone please help me i forgot to hand in my hw on the due date plzz anyone help me with those questions thank you!
Answer:
a)
(i) 43, 56
(ii) -1,3
b)-27
c) -21 +4n
Step-by-step explanation:
For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.
I got some money for my birthday. I save and spend in the ratio 2:3. I save £32. How much money did I receive for my birthday?
Answer:
80 i think
Step-by-step explanation:
32.3=80
Step-by-step explanation:
Amount of money saved : spent = 2 : 3.
Since amount of money saved = £32,
Amount of money spent = £32 * (3/2) = £48.
Total amount of money = £32 + £48 = £80.
Therefore I received £80 for my birthday.
Michael has 3 quarters, 2 dimes, and 3 nickels in his
pocket. He randomly draws two coins from his pocket,
one at a time, and they are both dimes. He says the
probability of that occurring is because 2 of the 8
coins are dimes. Is he correct? Explain.
My Answer:
The events are dependent.
The size of the original sample space is 8. It changes to 7 after the first dime is chosen.
The probability of picking the first dime is 2/8.
The probability of picking the second dime is 1/7
To find the probability of the compound event, multiply the probabilities.
I got it correct, on edge 2020/2021
Answer:
No. Choosing two dimes are dependent events. The probability of choosing the first dime is 14 and the probability of choosing the second dime is 17 . The probability that both coins are dimes is (14)(17) = 128.

Factorise x^2+13x+12
Step-by-step explanation:
Given
x² + 13x + 12
= x² + ( 12 + 1) x + 12
= x² + 12x + x + 12
= x ( x + 12 ) + 1 ( x + 12)
= (x + 12) (x + 1)

How do I fine x to the nearest tenth ??
Answer:
x = 13.6
Step-by-step explanation:
Here, we want to find the value of x
to find the value of x. we are going to use the sine rule
It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle
In this case;
11/ sin 27 = x/ sin 34
x = 11 sin 34/sin 27
x = 13.6
On the first visit to the veterinarian's office, Elijah's puppy weighed 19 ounces. On the 2nd visit, the puppy had gained 9 ounces. On the third visit, the puppy had gained another 7 ounces. What is the percent increase since the first visit in the puppy's weight rounded to the nearest percent?
a 84%
b 85%
c 79%
d 81%
Answer:
A)84%
Step-by-step explanation:
Orgin: 19 ounces
Second visit: 19+9=28 ounces
Third visit=28+7=35 ounces
35-19=16 ounces gained
16/19=84.2%=84% increase

Step-by-step explanation:
select all the expressions equivalent to 5x + 6x + 3x : 11x + 3x, 14x + x, 2 (3x + 4x), 3x(2 + 1) + 5x, 5x + 3(2x + x)
Step-by-step explanation:
5x + 6x + 3x
= 14x.
Now we compare the expressions with the result:
11x + 3x = 14x. (correct)
14x + x = 15x. (incorrect)
2(3x + 4x) = 2(7x) = 14x. (correct)
3x(2 + 1) + 5x = 3x(3) + 5x = 9x + 5x = 14x. (correct)
5x + 3(2x + x) = 5x + 3(3x) = 5x + 9x = 14x. (correct)
Hence our answers are the 1st, 3rd, 4th and 5th.
