Answer: 0.11
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.
Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us .11 or 0.11.
So 11% can be written as the decimal 0.11.

x > –5
Solution:
Given expression is –5 < 2x + 5.
Step 1: Let us first switch the sides.
⇒ 2x + 5 > –5
Step 2: Subtract 5 from both side of the inequality.
⇒ 2x + 5 –5 > –5 –5
⇒ 2x > –10
Step 3: Divide by 2 on both sides of the inequality.
[tex]$\Rightarrow\frac{2x}{2} >\frac{-10}{2}[/tex]
⇒ x > –5
Step 4: That is the values of x are greater than –5.
Hence x > –5.

if you have 108 inches of wood to make a picture fram what is the greatest area if a = -w2 + 54w
Answer:
The greatest area possible is 729[tex]inch^{2}[/tex]
Step-by-step explanation:
i) If a = [tex]-w^{2} + 54w[/tex] where w is the width of the picture frame
differentiating on both sides we get
[tex]\frac{da}{dw} = -2w + 54[/tex]
Differentiating the above again on both sides we get [tex]\frac{d^2a}{dw^2}[/tex] = -2
Since the second order derivative is negative then we can get the solution for the maximum area by equating the fist order derivative equation to 0.
Therefore -2w + 54 = 0 therefore w = 27.
ii) If we substitute w = 27 into the equation in ii) we get
a = [tex]-(27)^2 +(54\times 27)[/tex] = (54 - 27) [tex]\times[/tex](27) = [tex]27^{2}[/tex] = 729
Mrs. Pythagoras compares the distance traveled by three of her students. • Jason's distance travelled is given by the equation d =m, where, the total distance d traveled is given in m minutes. • Susan traveled(3 miles in 5 minutes.) The graph below represents the distance Mickey traveled.
please help me answer this math question
The student with the lowest unit rate is Mickey, with a unit rate of 0.3 miles per minute.
What is the relation of speed and distance?
Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.
The speed formula is speed = distance / time.
We are given that;
Equation d=m
Susan distance travelled=3 miles in 5 minutes
Now,
To find the unit rate, we need to divide the distance traveled by the time taken. Let's start by calculating the unit rate for each student:
Jason: The equation given for Jason's distance traveled is d = m, where d is the distance traveled in m minutes. Therefore, his unit rate is 1 mile per minute.
Susan: She traveled 3 miles in 5 minutes. To find her unit rate, we divide 3 miles by 5 minutes:
Unit rate = 3 miles / 5 minutes = 0.6 miles per minute
Mickey: The points on Mickey's distance vs time graph are (20,6), (40,12), and (60,18). We can use these points to calculate the unit rate for Mickey.
Between the points (20,6) and (40,12), the distance traveled is 12 - 6 = 6 miles, and the time taken is 40 - 20 = 20 minutes. Therefore, the unit rate is:
Unit rate = 6 miles / 20 minutes = 0.3 miles per minute
Between the points (40,12) and (60,18), the distance traveled is 18 - 12 = 6 miles, and the time taken is 60 - 40 = 20 minutes. Therefore, the unit rate is:
Unit rate = 6 miles / 20 minutes = 0.3 miles per minute.
Therefore, by distance given the answer will be 0.3 miles per minute.

Sarah answered 24 questions on her test correctly and earned an 80%. How many questions were on the test?
Answer:
43 questions in total
Step-by-step explanation:
the original equation with the unknown (total number of questions on the test) will look like this
[tex] \frac{total \: number \: of \: questions \: on \: exam}{24 \: answered \: questions} = 80\%[/tex]
we know this because to work out a percentage in the 1st place you need the total ÷ number (in this case it's ÷ how many questions out of the total she did answer)
now you rearrange.
you need to move the 24 to get the total on it's own here's how you do it
[tex] \frac{tot \: num \: of \: qs}{24} \times 24 = 80\% \times 24[/tex]
what you do to one side of equation you have to do to the other. the 24 and 24 on the left will cancel because 24÷24=1 and we don't write
got mum of Q's x 1= 80 x 24
now you convert % to decimal
[tex]80\% \times 100 = 0.80[/tex]
replace
[tex]tot \: num \: qs \: = 24 \times 0.80 = 19[/tex]
now you take the original and + the 19
[tex]24 + 19 = 43[/tex]
therefore there are a total of 43 questions on the exam
To find the total number of questions on the test, we set up a ratio where 24 questions represents 80%. By comparing it to a ratio where X represents 100%, and solving for X, we get the total number of questions.
Explanation:The question pertains to the concept of percentages. In Sarah's case, she answered 24 questions correctly and got an 80%, meaning that these 24 questions represent 80% of the total questions on the test. Hence, to find the total number of questions on the test, we set up a ratio such as this: 24 is to 80 as X (total questions) is to 100. We solve for X by multiplying the cross products and dividing by 80. The result will give us the total number of questions on the test.

Answer:
yes
Step-by-step explanation:
x + y = 3
3x + 2y = 14
The solution is x = 8 and y = -5
Solution:
Given system of equations are:
x + y = 3 ------ eqn 1
3x + 2y = 14 ------ eqn 2
We have to find the solution to the equations
We can use substitution method to solve
From eqn 1,
x + y = 3
Isolate for "x"
x = 3 - y ------ eqn 3
Substitute eqn 3 in eqn 2
3(3 - y) + 2y = 14
9 - 3y + 2y = 14
-y = 14 - 9
-y = 5
y = -5Substitute y = -5 in eqn 3
x = 3 - (-5)
x = 3 + 5 = 8
x = 8Thus the solution is x = 8 and y = -5

The quotient of the complex # below (7-2i)/(4 +3i)
Answer:
Step-by-step explanation:
hello :
(7-2i)/(4 +3i)
=(7-2i)×(4-3i)/(4 +3i)×(4-3i)
but : (7-2i)×(4-3i) =28-21i-8i+6i²
(7-2i)×(4-3i) = 22-29i ....i² = -1
(4 +3i)×(4-3i) = 4²-(3i)²...(identity)
= 16+9 =25
so :
(7-2i)×(4-3i)/(4 +3i)×(4-3i)
=(22-29i)/25
(7-2i)/(4 +3i) = 22/25 -29/25i

To divide complex numbers, multiply the numerator and denominator by the conjugate of the denominator.
Explanation:To divide complex numbers, we need to multiply the numerator and denominator by the conjugate of the denominator. The conjugate of 4 + 3i is 4 - 3i. So, we have ((7 - 2i) * (4 - 3i)) / ((4 + 3i) * (4 - 3i)).
Multiplying the numerators and the denominators, we get (28 - 21i - 8i + 6i^2) / (16 - 12i + 12i - 9i^2).
This simplifies to (28 - 29i - 6) / (16 + 9).
Finally, dividing the real parts and the imaginary parts separately, the quotient is:
Quotient = (22 - 29i) / 25

A married couple together earn $75,000. The husband earns $15,000 more than five times what his wife earns. What does the wife earn?
Answer:
$12,000
Step-by-step explanation:
Let's say the husband's income was $H, and the Wife's was W.
h + w = 75,000
H = 5w + 15, 000
Substitute that for H.
5w + 15,000 + w = 75,000
6w + 15,000 = 75,000
6w=60,000
w=12,000, So the wife earned $12,000.
