Answer 2

Answer: In 35 ways Jasmine can draw a blue or yellow marble from the jar


Step-by-step explanation:

Total marbles in the jar=number of blue marbles+number of yellow marbles=28+7=35.

The number of ways of drawing a blue or yellow marbles is given by

[tex]P^n_r=\frac{n!}{(n-r)!}[/tex]

Here n=35 and r=1

Therefore, [tex]P^{35}_1=\frac{35!}{(35-1)!}=\frac{35!}{34!}=\frac{35\times34!}{34!}=35[/tex]

Thus in 35 ways Jasmine can draw a blue or yellow marble from the jar.

how do you solve 1/3(2x-4)+5=-2/3(x+1)

Answers

Final answer:

Solving the equation 1/3(2x-4)+5=-2/3(x+1) involves distributing the fractions, combining like terms, and then multiplying by the reciprocal to isolate x, which results in a solution of x = -4.

Explanation:

To solve the linear equation 1/3(2x-4)+5=-2/3(x+1), you start by distributing the fractions across the parentheses and then combine them like terms. First, multiply 1/3 by each term inside the parentheses (2x-4) and -2/3 by each term inside (x+1), which gives:

2/3x - 4/3 + 5 = -2/3x - 2/3

Next, combine like terms and add 2/3x to both sides:

2/3x + 2/3x = -2/3 - 5 + 4/3

This simplifies to:

4/3x = -16/3

To isolate x, multiply both sides of the equation by the reciprocal of 4/3, which is 3/4:

x = (3/4) x (-16/3) = -4

The solution for x in the given equation is -4.

Final answer:

To solve the equation 1/3(2x-4)+5=-2/3(x+1), we need to simplify the equation and isolate the variable x. The solution to the equation is x = -7/12.

Explanation:

To solve the equation 1/3(2x-4)+5=-2/3(x+1), we need to simplify the equation and isolate the variable x. Let's start by distributing and solving the equation:

1/3(2x-4)+5=-2/3(x+1)

(2/3)x - 4/3 + 5 = (-2/3)x - 2/3

Combining like terms:

(2/3)x + 5/3 = (-2/3)x - 2/3

Add (2/3)x to both sides:

(2/3)x + (2/3)x + 5/3 = (-2/3)x + (2/3)x - 2/3

Simplify:

(4/3)x + 5/3 = -2/3

Subtract 5/3 from both sides:

(4/3)x + 5/3 - 5/3 = -2/3 - 5/3

Simplify:

(4/3)x = -7/3

Finally, divide both sides by 4/3 to solve for x:

(4/3)x / (4/3) = -7/3 / (4/3)

Simplify:

x = -7/12

Therefore, x = -7/12 is the solution to the equation.

Stacy and Neil painted 280 ft^2 of their living room wall with 4/5 gallon of paint. How many square feet can they paint with 3 gallons of paint? Enter your answer in the box.

Answers

we know that

Stacy and Neil painted [tex]280\ ft^2[/tex] of their living room wall with [tex]4/5\ gallon[/tex] of paint

so

by proportion

Find how many square feet can they paint with [tex]3[/tex] gallons of paint

[tex]\frac{280}{(4/5)} \frac{\ ft^{2} }{gallons} =\frac{x}{3} \frac{\ ft^{2} }{gallons} \\ \\x* \frac{4}{5} =3*280\\ \\x=\frac{5}{4}*3*280\\ \\x=1,050\ ft^{2}[/tex]

therefore

the answer is

[tex]1,050\ ft^{2}[/tex]

The square feet that can be painted with 3 gallons of paint is  1050 square feet.

The first step to take in order to determine the square feet that can be painted with 3 gallons, the square feet that can be painted with 1 gallon of paint has to be determined.

Number of square feet that can be painted with one gallon = 280 ft² ÷ [tex]\frac{4}{5}[/tex]

280 x [tex]\frac{5}{4}[/tex] = 280 feet

The second step is to determine the square feet can be painted with 3 gallons of paint.

280 feet x 3 = 1050 square feet.

The high school dance team is learning a new routine to a song that lasts 3 minutes and 41 seconds, or 221 seconds total. Yesterday, they covered the first 45 seconds of the song at practice. They learn an average of 22 seconds of the dance in an hour. Let h represent the time, in hours, it will take the team to learn the entire dance. Which equation represents this situation, and how long will it take?

Answers

221÷22=h=~10.05     221 secs ÷ 22 secs per h
equation: 45 + 22h =  221

The number of hours it will take is :

22h = 221-45
22h = 176
h = 176/22
h=8
so it takes them 8 more hours to finish learning the song.

How to understand the multiplication table

In a multiplication table, each row represents the product of a particular number (the row number) with the numbers in each column. If we consider rows 3 and 6, they represent the products of 3 and 6 with the numbers in each column.

The pattern observed in rows 3 and 6 is that the elements in the 6th row are exactly twice the corresponding elements in the 3rd row.  This pattern holds true because each element in row 6 is twice the corresponding element in row 3.

Hi there! So, the amount made is expected to increase by 20% from $25.9 billion next year. To find the projected amount, let’s multiply 25.9 billion by 120% 1.20.

Boris is playing on the mall escalators. One escalator goes up, one goes down, and one is out of service; otherwise, they're all identical. The up and down escalators go at the same speed. You can assume that Boris always runs at the same speed.

Boris can run up the up escalator in 6 seconds. He can run up the down escalator in 30 seconds. How long does it take him to run up the out-of-service escalator? Explain your answer

Answers

The answer to your question is 10 seconds. I know this because:

distance divided by speed=time
let t=time
t=2*6(30/36)=10
t=10
So, it took Boris a total of 10 seconds to run up the out of service elevator.

Hope this helps!

Answer:10 sec

Step-by-step explanation:

Given

Boris can run up the escalator in 6 sec

Also he can run up the down escalator in 30 sec

i.e. He travel same distance either ways

Let the distance be x and v be the speed of boris and [tex]v_0[/tex] be the speed of escalator.

[tex]x=6\times \left ( v+v_0\right )[/tex]----1

[tex]x=30\times\left ( v-v_0\right )[/tex]----2

Equating 1 and 2

[tex]5\left ( v-v_0\right )=v+v_0[/tex]

[tex]5v-5v_0=v+v_0[/tex]

[tex]v_0=\frac{2}{3}v[/tex]

substituting in 1

[tex]x=6\times \left ( v+v\frac{2}{3}\right )[/tex]

[tex]x=6\times v\frac{5}{3}=10v[/tex]

Thus form above equation we can say that it requires 10 sec for Boris to climb up in out of service escalator.

Stephen spent $4 on milk, $6 on eggs, and $11 on cereal. He wrote the ratio 6/11 to describe some of his purchases. Explain why the ratio is not a fraction.

Answers

Attached the solution and work.

The ratio 6/11 does not represent all of Stephen's purchases, as it excludes the $4 he spent on milk.

What is the ratio?

A ratio is a mathematical relationship that demonstrates how frequently one number contains or is contained inside another. Two numbers are compared using it.

If Stephen had written the ratio of the total amount spent on eggs and cereal to the amount spent on milk, it would have been:

(6 + 11) / 4 = 17/4

This ratio is also a fraction, but it cannot be simplified to a whole number, as the numerator and denominator have no common factors other than 1.

Therefore, the ratio 6/11 is a fraction that represents a comparison between two of Stephen's purchases, but it does not represent all of his purchases, and it is not the only possible ratio that can be written using the given information.

what is 0.4 as a simplified fraction

Answers

Answer: 2/5

Step-by-step explanation: Using the place value chart, we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4/10.

Notice however that 4/10 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2.

So if we divide the numerator and the denominator by 2, we get the equivalent fraction 2/5.

Therefore, 0.4 can be written as the fraction 2/5 which is in lowest terms.

if m<DCF =90 what is m<DCE

Answers

Final answer:

The measure of angle DCE is 90 degrees.

Explanation:

To find m <DCE, we need to use the fact that the angles in a triangle add up to 180 degrees.

Since m <DCF is 90 degrees, this means that DCF is a right angle. Therefore, the sum of m <DCF and m <DCE must be 180 degrees.

So, m <DCE = 180 - 90 = 90 degrees.
