Answer 1

Answer:

1) x=2

Step-by-step explanation:

1) 3(2x+1)=15

simplify both sides of the equation

3(2x+1)=15

(3)(2x)+(3)(1)=15 (distribute)

6x+3=15

subtract 3 from both sides

6x+3 -3 =15-3

6x=12

divide both sides by 6

6x/6 = 12/6

x=2

determine how many boxes of donuts (2) and bags of cookies (Y) to sell. They will earn $3 profit on each box of donuts and $1 profit on each bag of cookies.
Which could not be a way to earn enough money?
seling 25 boxes of donuts and 290 bags of cookies
selling 30 boxes of donuts and 260 bags of cookies
selling 45 boxes of donuts and 220 bags of cookies
selling 60 boxes of donuts and 160 bags of cookies

Answers

Answer:60 donut boxes and 160 cookies

Step-by-step explanation:

Multiply the boxes of donuts by $3, multiply the cookies by $1, add those two answers together to see if they equal at least 350

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The option that can not be a way to earn enough money is

Selling 60 boxes of donuts and 160 bags of cookies.

Option D is the correct answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount needed to earn = $350 or more

Profit from a box of donuts = $3

Profit from a box of cookies = $1

Now,

Selling 25 boxes of donuts and 290 bags of cookies.

= 25 x 3 + 290 = 75 + 290 = $365

Selling 30 boxes of donuts and 260 bags of cookies.

= 30 x 3 + 260 = $350

Selling 45 boxes of donuts and 220 bags of cookies.

= 45 x 3 + 220 = 135 + 220 = $355

Selling 60 boxes of donuts and 160 bags of cookies.

= 60 x 3 + 160 = 180 + 160 = $340

Thus,

The option that can not be a way to earn enough money is

Selling 60 boxes of donuts and 160 bags of cookies.

Option D is the correct answer.

The distance from Kim's house to NYC is 100 miles more than the distance from her house to LA. If the sum of the distances is 3,000 miles, how far is it from Kim's house to New York City?

Please help and show how you solved it!!

Answers

Answer:

1550miles

Step-by-step explanation:

assume her house to LA has x miles, therefore her house to NYC is x+100miles

x+x+100=3000

2x=2900

x=1450

x+100=1550miles

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 16 years, the

standard deviation is 1.7 years.

Use the empirical rule (68 - 95 - 99.7%) to estimate the probability of a gorilla living longer than 14.3

years.

Percent ____

Answers

Answer:

68%

Step-by-step explanation:

Empirical rule formula

= 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

From the above question,

Mean = 16 years

Standard deviation = 1.7 years

Score = 14.3 years

We have to find the number of standard deviation to determine the percentage

Hence,

14.3 = 16 - 1.7x

Collect like terms

1.7x = 16 - 14.3

1.7x = 1.7

x = 1.7/1.7

x = 1

This means the data falls within 1 standard deviation from the mean hence, the probability of the gorilla living longer than 14.3 years is 68%

If y = mx, and y is 12 when x is 4, then what is the constant of proportionality in this equation?

Answers

Answer:

3

Step-by-step explanation:

Given

y = mx ( m is the constant of proportionality )

Given y = 12 when x = 4 , then

12 = 4m ( divide both sides by 4 )

3 = m ← constant of proportionality

Answer:

m = 3

Step-by-step explanation:

Find the constant of proportionality by plugging in x and y into the equation, and solving for m

y = mx

12 = m(4)

Divide each side by 4

3 = m

So, the constant of proportionality is 3

Julie has picked 10× 3 silver three red three green and one orange she now has a 12% chance of picking which color

Answers

Answer:

None of the colors

Step-by-step explanation:

The given parameters can be represented as:

[tex]Silver = 3[/tex]

[tex]Red = 3[/tex]

[tex]Green = 3[/tex]

[tex]Orange =1[/tex]

[tex]Total = 10[/tex]

Required

Which has a probability of 12%

To do this, we calculate the probability of each color.

This is calculated as:

[tex]P(Color) = \frac{Color}{Total}[/tex]

So, we have:

[tex]P(Silver) = \frac{Silver}{Total}[/tex]

[tex]P(Silver) = \frac{3}{10}[/tex]

Express as percentage

[tex]P(Silver) = 30\%[/tex]

[tex]P(Red) =\frac{Red}{Total}[/tex]

[tex]P(Red) =\frac{3}{10}[/tex]

Express as percentage

[tex]P(Red) =30\%[/tex]

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

Express as percentage

[tex]P(Green) = 30\%[/tex]

[tex]P(Orange) = \frac{1}{10}[/tex]

[tex]P(Orange) = 0.1[/tex]

Express as percentage

[tex]P(Orange) = 10\%[/tex]

So, we have:

[tex]P(Silver) = 30\%[/tex]

[tex]P(Red) =30\%[/tex]

[tex]P(Green) = 30\%[/tex]

[tex]P(Orange) = 10\%[/tex]

From the above calculations, none of the colors have a probability of 12%.

Ellen is making smoothies. The recipe calls for 1 and 1/4 cups of strawberries. How many cups of strawberries, written as a fraction greater than one, are used in the recipe?

Answers

Answer:

the number of cups of strawberries needed in the recipe is ⁵/₄

Step-by-step explanation:

Given;

cups of strawberries needed for the smoothies =  1 and 1/4 cups

To obtain the number of cups of strawberries needed in the recipe as a single fraction, the given mixed fractions will be converted into an improper fraction.

Note: Improper fractions are always greater than 1

Number of cups of strawberries [tex]=1 + \frac{1}{4} = \frac{4 + 1}{4} = \frac{5}{4}[/tex]

Therefore, the number of cups of strawberries needed in the recipe is ⁵/₄
