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.

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

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

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

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%

Answer:

Step-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

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
