Answer: red = 10, orange = 20

Step-by-step explanation:

Let R represent the # of red skittles and G represent the # of orange skittles

there are 10 less red skittles than orange skittles: R = G - 10

orange skittles are twice the red skittles: G = 2R

Use substitution to solve the system:

 R = (2R) - 10

-R   -R        

0  = R - 10

+10     +10

10 = R

G = 2R   = 2(10)   = 20

Answer:

A) 30 cubes.

B) 30 units³.

Step-by-step explanation:

A) 1. Calculate the volume of the rectangular prism, as following:

[tex]Vr=(lenght)(width)(height)[/tex]

2. You have that:

- The length is: [tex]1^{\frac{1}{2}}ft=1.5ft[/tex]

- The width is: [tex]1ft[/tex]

- The heigth is: [tex]2^{\frac{1}{2}}ft=2.5ft[/tex]

3. Substitute these values into the formula:

[tex]Vr=(1.5ft)(1ft)(2.5ft)=3.75ft^{3}[/tex]

4. The volume of one cube is:

[tex]Vc=side^{3}[/tex]

5. The length of one side is: [tex]\frac{1}{2}ft=0.5ft[/tex]

6. Substitute this value into the formula:

[tex]Vc=(0.5ft)^{3}=0.125ft^{3}[/tex]

7. The number of small cubes that can be packed in the rectangular prism is:

[tex]cubes=\frac{Vr}{Vc}\\cubes=\frac{3.75ft^{3}}{0.125ft^{3}}\\cubes=30[/tex]

B) 1. The length, the width and the height of the rectangular prism in term of units cubes is:

[tex]Length=\frac{1.5ft}{0.5ft}=3units[/tex]

[tex]Width=\frac{1ft}{0.5ft}=2units[/tex]

[tex]Heigth=\frac{2.5ft}{0.5ft}=5units[/tex]

2. Therefore, the volume of the rectagular prism in terms of the small cube and a unit cube is:

[tex]Vr=(3units)(2units)(5units)=30units^{3}[/tex]

Answer:

30 cubes.

5 trips

Answer:- C) is the right answer. She can take 5 trips without exceeding her budget .

Explanation:-

Given: Budget for trips = $400

Amount needed by Kayla at the end of the trip= $100

Thus the exact amount she spends on trips= $400-$100= $300

Amount spend for each day trip = $ 60

Then The number of trips she can take[tex]=\frac{\text{Amount spend on trips }}{\text{Amount for each trip}}=\frac{300}{60}=5[/tex]

Thus she can take 5 trips without exceeding her budget .

the first few bars are the people who walked fewer than 4,000, so add up the numbers on the side (2 and 5) and you get 7, so a

7 people have averaged fewer than 4,000 steps.

Option A is the correct answer.

Given,

The bar graph of the number of steps on the horizontal line and the number of people on the vertical line.

We need to find how many people averaged fewer than 4,000 steps each day.

Read the bar graph.

Steps - 0 - 1,999

= 2 people

Steps - 2,000 - 3,999

= 5 people

Steps - 4,000 - 5,999

= 12 people

Steps - 6,000 - 7,999

= 7 people

Steps - 8,000 - 9,999

= 3 people

Find the number of people who have fewer than 4,000 steps.

We have,

Steps - 0 - 1,999

= 2 people

Steps - 2,000 - 3,999

= 5 people

So,

2 + 5 = 7

= 7 people

Thus 7 people have averaged fewer than 4,000 steps.

The solution to the equation is x = -10, which you can verify by plugging it back into the original equation.

The expression for the cost of Taxi B is 0.40x + 2.  The expression for the cost of Taxi A is 0.20x + 4.  The inequality asks for when the cost of Taxi B will be greater than Taxi A, so you write it as 0.40x + 2 > 0.20x + 4,  or  0.20x + 4 < 0.40x + 2.

The answer is B) 0.20x + 4 < 0.40x + 2.

Answer: B. [tex]0.20x+4<0.40x+2[/tex]

Step-by-step explanation:

let x denotes the number of mile taxi runs.

Given : Taxi A charges $0.20 per mile and an initial fee of $4.

i.e. the expression to show total charge by Taxi A will be :[tex]0.20x+4[/tex]

Taxi B charges $0.40 per mile and an initial fee of $2.

i.e. the expression to show total charge by Taxi B will be :[tex]0.40x+2[/tex]

Now, the inequality that can determine when the cost of Taxi B will be greater than Taxi A will be :-

[tex]0.20x+4<0.40x+2[/tex]

Hence, B is the correct answer.

Answer:

A) x²/25 + y²/9 = 1

Step-by-step explanation:

The major axis length is the sum of distances to the foci from the ellipse, 10. So the semi-major axis has length 10/2 = 5. The foci are on the x-axis, so the ellipse is oriented horizontally.

The semi-minor axis is the other leg of the right triangle having the focus and center as one leg, and the semi-major axis as the hypotenuse. This is obviously a 3-4-5 triangle, so the semi-minor axis length is 3.

When the ellipse is horizontal, the formula for it is ...

... (x/(semi-major axis))² + (y/(semi-minor axis))² = 1

... (x/5)² + (y/3)² = 1

... x²/25 + y²/9 = 1

Answer:

B.y=−3x−1

Step-by-step explanation:

given that the line is parallel to y = -3x+4

Hence required line will be of the form

y =-3x+k for some k.

(Reason: slopes will be equal for parallel lines)

Since the line passes through (-2,5)

Substitute x =-2 and y =5 in the equation.

5=-3(-2)+k

Simplify

5 = 6+k

Subtract 6

Or k =-1

Hence required line has equation y =-3x-1

Final answer:

To find the dimensions of the field with a perimeter of 600 feet where the length is three times the width, solve the equation derived from the perimeter formula. The width comes out to be 75 feet and the length 225 feet.

Explanation:

The question is about finding the dimensions of a rectangular field that is three times as long as it is wide, with a total perimeter of 600 feet. First, let's denote the width of the field as W and the length as 3W since the length is three times the width. The formula for the perimeter of a rectangle is 2(length + width), which in this case is 2(3W + W) = 8W. Given that the perimeter is 600 feet, we can set up the equation 8W = 600. Solving this for W gives us W = 75 feet. Therefore, the length, being three times the width, is 225 feet.

So, the dimensions of the field are 75 feet in width and 225 feet in length.

When P and Q are equal there is no solution exist.

For example - (0,0) , (1,1)  

Step-by-step explanation:

Given : Equation [tex]Px+40=Qx+20[/tex]

To find : Which values of P and Q result in an equation with no solutions?

Solution :

In the given equation [tex]Px+40=Qx+20[/tex]        

P, Q, x are variable.

We have to find the values at which the equation has no solutions.  

[tex]Px+40=Qx+20[/tex]

The fraction of those who are scared of spiders and also scared of snakes is 1/2.

A fraction is a way of representing a part of a whole or a division of quantities. It consists of two components: a numerator and a denominator, separated by a horizontal line called a fraction bar.

We have,

1/3 of the children are scared of spiders and 1/6 of both snakes and spiders, we can find the fraction of those who are scared of spiders and snakes by dividing the overlap by the total number scared of spiders.

Fraction scared of spiders and snakes

= (Overlap) / (Total scared of spiders)

Overlap = 1/6

Total scared of spiders = 1/3

Fraction scared of spiders and snakes = (1/6) / (1/3) = (1/6) * (3/1) = 1/2

Therefore, the fraction of those who are scared of spiders and also scared of snakes is 1/2.

Final answer:

Half of the children who are scared of spiders are also scared of snakes, calculated by dividing the fraction of children scared of both by those scared of spiders.

Explanation:

To find the fraction of those who are scared of spiders that are also scared of snakes, we start with the information that 2/3 of the children are scared of snakes, 1/3 are scared of spiders, and 1/6 are scared of both snakes and spiders. Since we want to find out the fraction of those scared of spiders (1/3 of the total) who are also scared of snakes, we focus on the 1/6 portion that represents children scared of both. This fraction is relative to the whole group. To express it as a fraction of just those scared of spiders, we divide the fraction of both phobias (1/6) by the fraction scared of spiders (1/3).

Calculation: (1/6) ÷ (1/3) = (1/6) * (3/1) = 1/2.

Therefore, 1/2 of those who are scared of spiders are also scared of snakes.

Answer: the first choice, |x − 18.25| > 0.36; x < 17.89 or x > 18.61

Explanation:

1. Target weight: 18.25 oz

2. Variability accepted: 0.36 oz

3. Range of accepted masses: 18.25 oz - 0.36 oz ≤ x ≤ 18.25 oz + 0.36 oz

4. Addition property of the inequalities (subtract 18.25 oz to the three parts of the inequality):

- 0.36 oz ≤ x - 18.25 oz ≤ 0.36 oz

5. Definition of absolute value inequality: | x - a | ≤ c equals - c ≤ x - a ≤ c

   ∴ - 0.36 ≤ x - 18.25 ≤ 0.36  equals | x - 18.25 | ≤ 0.36, which is the range of accepted masses.

6. The range of rejected masses is the complement, so it is:

          |x - 18.25 | > 0.36

7. Solve the inequality to find the range of rejected masses:

    a) x - 18.25 > 0.36 ⇒ x > 18.25 + 0.36 ⇒ x > 18.61

    b) x - 18.25 < 0.36 ⇒ x < 18.25 - 0.36 ⇒ x < 17.89
