I’m at so confused !!

Answer:

60%

Step-by-step explanation:

P(A or B) = P(A) + P(B)

175/500 are wool and 125/500 are nylon

Add them to get 300/500 or 3/5 or 60%

There are 300 coats that are either wool or nylon.

A store has 500 winter coats. 35% are wool, and 1/4 are nylon.

To find the number of coats that are either wool or nylon, we add the number of wool coats and nylon coats.

First, calculate the number of wool coats: 500 coats * 35% = 0.35 * 500 = 175 wool coats.

Then, calculate the number of nylon coats: 500 coats * 1/4 = 500 * 1/4 = 125 nylon coats.

Finally, add the number of wool and nylon coats to find the total number of coats that are either wool or nylon: 175 wool coats + 125 nylon coats = 300 coats.

Final answer:

Ceci's driving rate is 75 miles per hour. To drive 1.125 miles at this rate, it would take her 0.015 hours, or approximately 0.9 minutes.

Explanation:

The question requires the calculation of Ceci's driving rate and then using it to determine how long it will take her to drive a shorter distance. First, we determine Ceci's driving rate:

Rate = Distance ÷ Time

Ceci's rate of driving is calculated by dividing the distance she can drive, 225 miles, by the time it takes her, which is 3 hours.

Rate = 225 miles ÷ 3 hours = 75 miles/hour

With the rate calculated, we can now determine how long it takes her to drive 1.125 miles:

Time = Distance ÷ Rate

Thus, the time to drive 1.125 miles at 75 miles/hour is:

Time = 1.125 miles ÷ 75 miles/hour = 0.015 hours, or approximately 0.9 minutes (since there are 60 minutes in an hour). To drive 1.125 miles at this rate, it would take her 0.015 hours, or approximately 0.9 minutes.

The weight of the gorilla at its birth is 16 pounds

Step-by-step explanation:

Step 1 :

The equation representing the weight of the gorilla in its first month of life is given as  

P= 16 + 4 w

Where P represents the weight in pounds and

w represents the number of weeks since birth

We need to find the weight of the gorilla at birth

Step 2 :

The number of weeks since birth of the gorilla will be zero at its birth. Hence the variable w will be 0 at its birth.

Substituting this in the above equation we have.

Step-by-step explanation:

your welcome

Answer:

88/35

Step-by-step explanation:

First, change the mixed numbers into the improper fractions, 22/7 and 5/4. Now you can divide. I use a method called KCF, which means Keep Change Flip. Here is your expression: 22/7 / 5/4. Keep the first fraction. Change the sign; change the division sign into a multiplication symbol. Now you have 22/7 x 5/4. Finally, flip the last fraction into 4/5. Now you have 22/7 x 4/5. Multiply numerator by numerator, denominator by denominator to get 88/35. You can also simplify this into 2 18/35.

Final answer:

John will need 4.5 bottles of paint to cover the entire cube, with one-eighth of a bottle covering one-sixth of one face and a cube having 6 faces.

Explanation:

The question asks how many bottles of paint John will need to paint the entire cube. If one-eighth of a bottle covers one-sixth of one face, then to cover the whole face, John would need 6 times the amount of paint for one-sixth of the face, which is 6 x 1/8 = 3/4 of a bottle. Since a cube has 6 faces, he will need 6 times 3/4 bottles to paint the entire cube. Therefore, John will need 4.5 bottles to paint the entire cube, as each face requires 3/4 of a bottle and there are 6 faces.

The point A on the number line represents -4.

Step-by-step explanation:

Step 1:

The distance between 0 and -5 is split into 5 partitions.

The value for each distance is given by dividing the difference by the number of partitions.

So each partition represents a value of [tex]\frac{5}{5}=1[/tex] unit.

Step 2:

Since it is going on the negative side of the number line, the numbers vary by a value of -1 each.

The value of the first partition; [tex]-1(1) = -1[/tex],

The value of the second partition; [tex]-1(2) = -2[/tex],

The value of the third partition; [tex]-1(3) = -3[/tex],

The value of the fourth partition; [tex]-1(4) = -4[/tex],

The value of the fifth partition; [tex]-1(5) = -5[/tex].

The point A on the number line is in between the zero and the fifth partition so it is the fourth partition which has a value of -4.

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients. The given polynomial as the product of two binomials x²-9x+20 can be expressed as (x-5)(x-4).

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

The given polynomial can be factorized as shown below.

x² - 9x + 20 = 0

Divided the middle term into two terms such that the sum of those two terms is -9, while the product of those two terms is +20.

Therefore, the two terms will be -5 and -4.

= x² - 5x - 4x + 20

Taking x as the common term from the first two terms and -4 as the common term from the last two terms.

= x(x-5)-4(x-5)

Taking (x-5) as the common term from the two formed terms,

=(x-5)(x-4)

Hence, the given polynomial as the product of two binomials x²-9x+20 can be expressed as (x-5)(x-4).

Answer:

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  [tex]\frac{C}{5}[/tex] ⇒ answer C

Step-by-step explanation:

In any circle there is a constant ratio between the circumference of the circle and its diameter

This constant ratio is called π

∵ The formula of the circumference of a circle is C = π d,

    where d is the diameter of the circle

- Divide both sides by d

∴ [tex]\frac{C}{d}[/tex] = π

- Switch the two sides

∴ π =  [tex]\frac{C}{d}[/tex]

∵ The diameter of the circle is 5 centimeters

∴ π =  [tex]\frac{C}{5}[/tex]

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  [tex]\frac{C}{5}[/tex]

To solve this question, we need to think about the relationship between the circumference (C) of a circle and its diameter (d). The formula that describes this relationship is C = π * d.
Now, if the diameter (d) of the circle is 5 centimeters, then substituting this into the formula, we get:
C = π * 5
We want to find how this is equivalent to π, so we need to solve for π. To isolate π, we can divide both sides of the equation by 5:
C / 5 = (π * 5) / 5
Now, dividing 5 on the right side of the equation cancels it out:
C / 5 = π
This equation shows that π is equal to the circumference divided by the diameter of the circle. Since the diameter is 5 centimeters, the correct way to write this is:
π = C / 5
Which corresponds to option C.

Answer:

scale

Step-by-step explanation:

The scale is the ratio of the size of a model compared to the real object. A model is made to represent a real object that was too big (like building, bridge, car) or too small(bacteria, atoms, molecule). Having a model can help someone to visualize the real object easier.  Scale can be represented as a percentage, or ratio.

Explanation:

To solve the proportion 2/3 = n/12, you begin by cross multiplying to find the value of n. This means you multiply 2 by 12 and 3 by n. The equation now looks like this: 2×12 = 3×n.

Next, simplify the left side of the equation, which results in 24 = 3×n.

Finally, solve for n by dividing both sides of the equation by 3, leading to n = 8.

This method of cross multiplication and division is a common technique used to solve proportions and find missing values in ratios.
