Answer:
Step-by-step explanation:
We can start off by putting this into an equation. Kalil's monthly salary is not a changing value, so that stays put. However, any additional money he gets from selling his stuff, he gets to keep 1.4%.
Thus, we can just add his salary and his commission earnings.
To find the commission, we just multiply 1.4% by $51,000 (the total sales, not his salary).
Thus, Kalil got $3964 in July.
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

The angle between a diagonal and the longer base of the isosceles trapezoid MNFD is 45°. NK is an altitude to the longer base. If MD = 9 and NF = 5, find:
Answer:
NK = 7, MK = 2, MF = 9.9, Area = 42Step-by-step explanation:
Refer to attached
To find:
NK , MK, MF, Area of trapezoidSolution
The trapezoid is isosceles and NK is its height, therefore
MD - NF = 2MKMK = (9 -5)/2 = 2Since ∠KDN = 45°, the triangle NKD is isosceles and so
NK = KD = MD - MK = 9 - 2 = 7MF = ND as trapezoid is isosceles and therefore diagonals are equal
ND = NK√2 = 7√2 = 9.9 So MF = 9.9Area of trapezoid

Lucy can spend no more than $125 on props for a school play. She has already phurchased costume fabrics that cost $49. Write and solve an inequality to show how much more she spend on props.
Answer: 49+x≤ 125, where x = Amount she can spend more on props.
Now she can spend no more than $76 on props.
Step-by-step explanation:
Given: Lucy can spend no more than $125 on props for a school play.
I.e. Total money she can spend ≤ $ 125
She already purchased costume fabrics that cost $49.
Let x = Amount she can spend more on props.
Required inequality: 49+x≤ 125
Subtract 49 from both sides, we get
x≤ 76
Hence, now she can spend no more than $76 on props.

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

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

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%

Correct question is;
1) Milk and cream are mixed together for a recipe. The total volume of the mixture is 1 cup. If the milk contains 2% fat, the cream contains 18% fat, and the mixture contains 6% fat, how much cream is in the mixture?
2) Fifteen percent of the pigment in paint color A is black. Sixty percent of the pigment in paint color B is black. An unknown amount of paint color B is mixed with 40 ml of paint color A, resulting in a paint that contains 25% black pigment. Which equation can be used to solve for x, the total amount of paint in the mixture of the two colors?
A) 0.15(40) + 0.6x = 0.25(40 + x)
B) 0.15(40) + 0.6(x – 40) = 0.25(x)
C) 0.15(40) + 0.6x = 0.25(40 – x)
D) 0.15(40) + 0.6(x + 40) = 0.25(x)
Answer:
1) Amount of cream = ¼cup
2) Option D: 0.15(40) + 0.6(x - 40) = 0.25x
Step-by-step explanation:
1) First of all, let x represent the amount of cup of milk and let y represent the of cup of cream.
We are told that the volume of the mixture is 1 cup.
Thus;
x + y = 1 - - - (eq 1)
We are now told that the milk contains 2% fat, the cream contains 18% fat, and the mixture contains 6% fat
Thus, x contains 0.02 fat, y contains 0.18 fat and the 1 cup of mixture contains 0.06 fat.
Thus, we will multiply the respective terms in eq 1 by these %fat content.
Thus;
0.02x + 0.18y = 0.06(1)
0.02x + 0.18y = 0.06 - - - (eq 2)
From eq 1, let's make y the subject which is the amount of cup of cream.
Thus,
y = 1 - x
Let's put 1 - x for y in eq 2 to get;
0.02x + 0.18(1 - x) = 0.06
0.02x + 0.18 - 0.18x = 0.06
0.18x - 0.02x = 0.18 - 0.06
0.16x = 0.12
x = 0.12/0.16
x = 3/4 cup
From,y = 1 - x;
y = 1 - (3/4)
y = ¼ cup
Amount of cream = ¼cup
2) We are given;
15% of the pigment in paint color A is black.
60% of the pigment in paint color B is black.
We are now told that Alan unknown amount of paint color B is mixed with 40 ml of paint color A, resulting in a paint that contains 25% black pigment.
If we assume the total amount of paint in the mixture is x like we are told, it means that based on the given data, we have a sum of;
0.15(40) + 0.6(x - 40)
Thus is because we know the amount of paint A used as 40 but don't know the amount of paint B used.
Now we are told that this sum produces a mixture that contains 25% black pigment. Since the total amount in the mixture is x. Thus, this final product is 0.25x.
Therefore to derive an equation to find the total amount of paint in the mixture of the two colors, we will equate the sum of the 2 Mixtures to the final product.
This gives;
0.15(40) + 0.6(x - 40) = 0.25x
The weights of 3 puppies at one week old were 6.5 ounces, 7.3 ounces, and 6.4 ounces. Of each puppy gained 2.1 ounces, how much would the puppies weigh?
Answer:
Puppy 1 = 8.6 ounces
Puppy 2 = 9.4 ounces
Puppy 3 = 8.5 ounces
Step-by-step explanation:
Weights of 3 puppies at one week old were
Puppy 1 = 6.5 ounces
Puppy 2 = 7.3 ounces
Puppy 3 = 6.4 ounces
Each puppy gained 2.1 ounces
Puppy 1 = 6.5 ounces + 2.1 ounces
Puppy 2 = 7.3 ounces + 2.1 ounces
Puppy 3 = 6.4 ounces + 2.1 ounces
New weight
Puppy 1 = 8.6 ounces
Puppy 2 = 9.4 ounces
Puppy 3 = 8.5 ounces
If the puppies each gained 2.1 ounces, the new weight is given above
