Answer:
100 meters is 8.6 meters longer than 100 yards.
Step-by-step explanation:
Conversion of yards to meters.
Each yard has 0.914 meters.
So 100 yards is 100*0.9144 = 91.4 meters.
How many meters longer to the nearest tenth is 100 meters than 100 yards?
100 yards = 91.4 meters
100 - 91.4 = 8.6
So 100 meters is 8.6 meters longer than 100 yards.
A local courier service estimates its monthly operating costs to be $1500 plus $0.85 per delivery. The service generates revenue of $6 for each delivery. Let x = the number of deliveries in a given month. The function C(x) = .85x + 1500 represents the operating cost. The function R(x) = 6x represents the revenue generated. Knowing that profit = revenue - cost, write a function, P(x), that represents the monthly profits for making x deliveries per month.
Answer:
P(x) = 5.15 x + 1500
Step-by-step explanation:
The monthly operating costs = $1500 plus $0.85 per delivery.
The service generates revenue= $6 for each delivery
If in a given month the deliveries number was = x then;
Operating cost function : C(x) = 0.85x + 1500
Revenue generated function R(x) = 6x
Profit = Revenue - cost
P(x) = R(x) - C(x)
P(x) = 6x - 0.85x + 1500
P(x) = 5.15 x + 1500
Write the percent as a mixed number in simplest form.
168%
Answer:
1 and 17/25
Step-by-step explanation:
First, you make it into a fraction. So because percents are out of 100, it would be 168/100. Then, you take 100 out of it to get a mixed number, 1 and 68/100, and then simplify 68/100 by dividing both sides by the greatest common factor, which is 4. 68/100÷4=17/25. The answer would be 1 and 17/25.

- 2x - 5y=-12
10x - 4y = 2
Answer:
[tex]x=1, y=2[/tex]
Step-by-step explanation:
[tex]\begin{bmatrix}-2x-5y=-12\\ 10x-4y=2\end{bmatrix}[/tex]
Isolate x for [tex]-\:2x\:-\:5y=-12[/tex]
[tex]-\:2x\:-\:5y=-12[/tex]
Add 5y to both sides.
[tex]-2x-5y+5y=-12+5y[/tex]
Simplify.
[tex]-2x=-12+5y[/tex]
Divide both sides by 2.
[tex]x=-\frac{-12+5y}{2}[/tex]
Substitute x for [tex]-\frac{-12+5y}{2}[/tex].
[tex]\begin{bmatrix}10\left(-\frac{-12+5y}{2}\right)-4y=2\end{bmatrix}[/tex]
Simplify.
[tex]\begin{bmatrix}-29y+60=2\end{bmatrix}[/tex]
Isolate y for [tex]-29y+60=2[/tex]
[tex]y=2[/tex]
Substitute y in [tex]-\frac{-12+5y}{2}[/tex] for 2.
[tex]x=-\frac{-12+5\cdot \:2}{2}[/tex]
Simplify.
[tex]x=1,\:y=2[/tex]

Answer:

Answer:
p = 20
Step-by-step explanation:
In order to solve for "p", you need to isolate p completely on one side of the equal sign. to do such, simply multiply by "4" both sides ofthe equation, to cancel out the 4 in the denominator and get:
p = 5 * 4 = 20

mary ann spent $26.85 total on two new toys. She had a coupon for 1.00 off her total purchase and spend 1.75 on sales tax. Each toy cost the same amount how much did each toy cost?
Answer: $13.80
Step-by-step explanation:
Mary ann spent $26.85 total on two new toys but had a coupon for $1.00 off her total purchase. Therefore, we subtract $1.00 from $26.85. This will be:
= $26.85 - $1.00
= $25.85
Shw then spend $1.75 on sales tax. Total coat will now be:
= $25.85 + $1.75
= $27.60
Since each toy coat same amount, therefore each toy will cost:
= $27.60 / 2
= $13.80
Which of the following inequalities represents the graph shown below on
the real number line?
Answer:
-3 < x ≤ 1
Step-by-step explanation:
To our left, we have an unshaded circle at -3. This means that -3 is included in the possible value of x. And as such, we can say -3 < x.
To our right, we have a shaded circle at 1. This means 1 is included in the possible values of x. And as such, we can say x ≤ 1.
Thus, we can represent the two statements as one, thus:
-3 < x ≤ 1

A quantity with an initial value of 230 decays continuously at a rate of 7% per year. What is the value of the quantity after 8.7 decades, to the nearest hundredth?
The answer is ≈0.52
Answer:
≈0.52
Step-by-step explanation:
The value of the quantity after 8.7 decades is 0.521.
What is Exponential Growth and Decay?Exponential growth is the increase of rate of change and thus results in the increase of the final quantity.
Exponential decay is the decrease in rate of change and hence results in the decrease of the final quantity.
Given that,
Initial value of the quantity = 230
Rate of decay = 7% per year = 0.07
Time = 8.7 decades = 87 years
The formula for exponential decay is,
A = P e^(-k t)
Here A is the final value of the quantity
P is the initial value of the quantity
k is the decay rate
t is the time.
Substituting the given values,
A = 230 × e^(-0.07 × 87)
A = 230 × e^(-6.09)
= 0.521
Hence the final quantity after 8.7 decades is 0.521.

Regina is buying a new car. She sees two advertisements in the paper for the same car at two different prices from two different dealerships. Both dealers are offering a simple-interest loan for the price of the car. A photo of car includes two ads. Ad A shows the vehicle priced at twenty-four thousand two hundred dollars at six point five percent interest and an unknown number of years. Ad B shows an unknown price, at a five point three percent interest over nine years. Question 1 Part A Regina calculates that to buy the car in Ad A, the loan would ultimately cost her $41,503. Over how many years is the loan in Ad A to be paid back?
Answer:
11 years
Step-by-step explanation:
Given that:
Advert A:
Principal, p = $24,200
Interest rate, r = 6.5% = 6.5/100 = 0.065
Time, t =?
Total Repayment, A = $41,503
Using the relation :
A = p(1 + rt)
Plugging our values
41503 = 24200(1 + 0.065t)
41503 / 24200 = 1 + 0.065t
1.715 = 1 + 0.065t
1.715 - 1 = 0.065t
0.715 = 0.065t
t = 0.715 / 0.065
t = 11 years
Loan in Advert A will be paid back in 11 years
Answer:
11 years
Step-by-step explanation:
Given that:
Advert A:
Principal, p = $24,200
Interest rate, r = 6.5% = 6.5/100 = 0.065
Time, t =?
Total Repayment, A = $41,503
Using the relation :
A = p(1 + rt)
Plugging our values
41503 = 24200(1 + 0.065t)
41503 / 24200 = 1 + 0.065t
1.715 = 1 + 0.065t
1.715 - 1 = 0.065t
0.715 = 0.065t
t = 0.715 / 0.065
t = 11 years
Loan in Advert A will be paid back in 11 years
Why is 16 the answer to 10. x / 2 - 5 = 3? I need an answer today.
Hi there!
[tex]\large\boxed{x = 16}[/tex]
x / 2 - 5 = 3
Begin by adding 5 to both sides to isolate for x:
x / 2 - 5 + 5 = 3 + 5
x / 2 = 8
Multiply both sides by 2 to have "x" alone on the left-hand side:
(x / 2) × 2 = 8 × 2
x = 16
Answer:
because if x is 16
16/2 = 8 and so on 8 - 5= 3 so that is the answer

In one town, 47% of all voters are Democrats. If three
voters are randomly selected for a survey, what is the
probability that they are all Democrats?
Answer:
The probability that the all three votes are Democrats
P(X=3) = 0.1038
Step-by-step explanation:
Step(i):-
Given that the all voters are democrats
The probability that the all voters are democrats
p = 47% =0.47
q = 1-p =1-0.47 = 0.53
Step(ii):-
Let 'X' be the random variable in binomial distribution
[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]
The probability that the all three votes are Democrats
P(X=3) = 0.1038
n=3 and r=3
[tex]P(X=3) = 3_{C_{3} } (0.47)^{3} (0.53)^{3-3}[/tex]
[tex]P(X=3) = 1 (0.47)^{3}[/tex]
P(X=3) = 0.1038
Final answer:-
The probability that the all three votes are Democrats
P(X=3) = 0.1038

Need the answer ASAP
Answer: 2430 bacteria.
Step-by-step explanation:
When we have a quantity A, and we have an increase of the X%, the new quantity can be written as:
A + (X%/100%)*A
In this case, we have A = 10 bacteria.
And X% = 200%.
Then if we start with 10 bacteria.
After one day, we will have:
10 bacteria + (200%/100%)*10 bacteria
= 10 bacteria + 2*10 bacteria = 3*10 bacteria.
After another day, we will have:
3*10 bacteria + (200%/100%)*(3*10 bacteria)
3*10 bacteria + 2*(3*10 bacteria)
3*(3*10 bacteria)
10 bacteria*(3)^2
We already can see the pattern here.
After t days, we will have:
10 bacteria*(3)^t.
This is the equation f(t) we wanted:
f(t) =10 bacteria*(3)^t
after 5 days, we will have:
f(5) = 10 bacteria*(3)^5 = 2430 bacteria.
