A boat rental company recommends a boat that can go 402 miles on LaTeX: \frac{23}{2}23 2 gallons of gasoline. However there are other boats available that have better fuel efficiency. Their rates miles to gallons are listed. Select the rates that have better miles per gallon than the recommended boat.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Distance = 402\ miles[/tex]
[tex]Gasoline = 23/2\ gallons[/tex]
Required
Determine boats with better rates
This question requires options which are missing. However, I'll give an explanation on how to determine the right answers.
First, determine the rate of the given boat by dividing distance by amount of gasoline.
[tex]Rate = Distance/Gasoline[/tex]
[tex]Rate = 402\ miles / \frac{23}{2}\ gallons[/tex]
[tex]Rate = 402\ miles * \frac{2}{23\ gallons}[/tex]
[tex]Rate = \frac{402\ miles * 2}{23\ gallons}[/tex]
[tex]Rate = \frac{804\ miles}{23\ gallons}[/tex]
[tex]Rate = 34.96\ miles/gallon[/tex]
For the list of mission options, calculate the rate using the same formula used above... then compare the results.
Take for instance, we have a boat with:
[tex]Distance = 500\ miles[/tex]
[tex]Gasoline = 10\ gallons[/tex]
Rate would be:
[tex]Rate = 500\ miles/10\ gallons[/tex]
[tex]Rate = 50\ miles/gallons[/tex]
By comparing these rates, we have that:
[tex]50 > 34.96[/tex]
So, this new boat has a better rate than the given boat.
Apply this on the missing options
The 2020 Election is shaping up to be the largest one yet! They estimate that there are 240,000,000 eligible voters in the United States this year. So far, 70,000,000 have voted, and experts estimate that upwards of 150,000,000 people will vote in total this year. What percentage of eligible voters will participate in this year's election?
Answer:
Percentage = 91.67%
Step-by-step explanation:
Number of eligible voters = 240,000,000
Number of voters so far = 70,000,000
Number of estimated voters = 150,000,000
Total number of participants (voters) = 70,000,000 + 150,000,000 = 220,000,000
To find the percentage;
[tex] Percentage = \frac {220,000,000}{240,000,000} * 100 [/tex]
[tex] Percentage = \frac {11}{12} * 100 [/tex]
[tex] Percentage = 0.9167 * 100 [/tex]
Percentage = 91.67%
Therefore, the percentage of eligible voters that will participate in this year's election is 91.67%

91.67%

El peso promedio de 500 árboles de un vivero es de 70kg y la desviación estándar de 3kg. Suponiendo que los pesos se distribuyen normalmente, encontrar CUANTOS arboles pesan: a) Entre 60 y 75 kg b) Más de 90kg c) Menos de 64kg. D) 64 Kg
Answer:
Step-by-step explanation:
Resolvemos usando la fórmula de puntuación z
z = (x-μ) / σ, donde
x es la puntuación bruta
μ es la media poblacional = 70 kg
σ es la desviación estándar de la población = 3 kg
a) Entre 60 y 75 kg
Para x= 60kg
z = 60 - 70/3 kg
=-3.33333
Valor de probabilidad de la tabla Z:
P(x = 60) = 0.00042906
Para x = 75 kg
z = 75 - 70/3 kg
= 1.66667
Valor de probabilidad de la tabla Z:
P(x = 75) = 0.95221
P(x = 75) - P(60)
0.95221 - 0.00042906
b) Más de 90 kg
Para x> 90 kg
z = 90 - 70/3
= 6.66667
Valor de probabilidad de la tabla Z:
P (x <90) = 1
P (x> 90) = 1 - P (x <90) = 0
Número de árboles = 500
Por tanto, 500 × 0 = 0 árboles
c) Menos de 64 kg
x <64 kg
z = 64 - 70/3 kg
= -2
Valor de probabilidad de Z-Table:
P (x <64) = 0,02275
Hay 500 arboles
= 500 × 0.02275
= 11.375 árboles
D) 64 kilogramos
x = 64 kg
z = 64 - 70/3 kg
= -2
Valor de probabilidad de Z-Table:
P (x = 64) = 0,02275
Hay 500 arboles
= 500 × 0.02275
= 11.375 árboles

Greta is taking a road trip from Cincinnati to San Francisco. On the first day, she drove 650 miles in 10 hours. On the second day, she got a later start and drove 540 miles in 8 hours. How many miles per hour faster was her average speed the second day?
Answer:
2.5 miles per hour fasterStep-by-step explanation:
Step one:
the first day
distance= 650miles
time taken= 10 hours
speed= distance/time
speed= 650/10
speed= 65miles per hour
Step two:
the second day
distance= 540mile
time taken= 8 hours
speed= distance/time
speed= 540/8
speed= 67.5miles per hour
Step three:
the difference between the two speeds is =67.5-65= 2.5
therefore on the second day, the speed is 2.5 miles per hour faster

What is t if the equation is
-8t=27+t
Answer:
t = -3
Step-by-step explanation:
Given: -8t = 27 + t, we must isolate the variable; in this case, the variable is t.
So, to isolate the variable, we will move all terms containing t to the left side of the equation.
Therefore,
-9t = 27
Then, we divide each term by -9 and simplify.
We get:
t = -3
