2 18/35

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.

Step-by-step explanation:

1) A number m is at least four

m ≥ 4  ['at least' = ≥ symbol]

2) 4x  ≤ 20x; x=2

4(2) ≤ 20(2)

8 ≤ 40

[Im not sure if this is a solution or and inequality :/ ]

3)  x < 5

The Main Answer is the best estimation of the fraction of the batch that was left is [tex]59/168[/tex].

To find the fraction of the batch that was left, we first need to calculate how much was given away to the neighbors and how much Mr. Gallegos ate himself, then subtract those amounts from the total batch.

1. Given that Mr. Gallegos gave [tex]11/21[/tex] of the batch to his neighbors, and ate 1/8 of the batch himself.

2. We need to find the total amount given away and eaten: [tex]Total given away = 11/21[/tex] [tex]Total eaten by Mr. Gallegos = 1/8[/tex]

3. To find the fraction left, subtract the total given away and eaten from the total batch (1): [tex]Fraction left = 1 - (11/21 + 1/8)[/tex]

Now, let's calculate:

To subtract fractions, they must have the same denominator. The least common multiple (LCM) of [tex]21[/tex] and [tex]8[/tex] is [tex]168[/tex]. We'll rewrite the fractions with a common denominator of [tex]168[/tex]:

[tex]11/21 = (11/21) * (8/8) = 88/168 \\1/8 = (1/8) * (21/21) = 21/168[/tex]

So, the expression becomes:

[tex]Fraction left = 1 - (88/168 + 21/168) \\= 1 - (109/168)[/tex]

To subtract [tex]109/168[/tex] from [tex]168/168[/tex] (which equals 1), we'll subtract the numerators:

[tex]Fraction left = (168/168) - (109/168) \\= 59/168[/tex]

Therefore, the best estimation of the fraction of the batch that was left is [tex]59/168[/tex].

COMPLETE QUESTION:

Answer:

Problem #1:  x = 2.5

Problem #2:  x = 10/7

Step-by-step explanation:

Step 1:  Find the value of x in (8x - 20)

8x - 20 = 0

Add 20 to both sides

8x - 20 + 20 = 0 + 20

8x = 20

Divide both sides by 8

8x / 8 = 20 / 8

x = 2.5

Answer:  x = 2.5

Step 2:  Find the value of x in (14x - 20)

14x - 20 = 0

Add 20 to both sides

14x - 20 + 20 = 0 + 20

14x = 20

Divide both sides by 14

14x / 14 = 20 / 14

x = 10/7

Answer:  x = 10/7

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 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)

Angle ACB = 67

Step-by-step explanation:

Angle DAB and BAC are supplementary angles. This means they add up to 180 degrees. So subtract 127 from 180 to find angle BAC which is 53. We know that a triangle's degrees add up to 180. So take 180 and subtract (60+ 53) to find angle ACB.

The angles around point A should add up to 360° ∠ACB is 173°.

In the given diagram where ∠ABC is 60° and ∠DAB is 127°, you can find ∠ACB by using the fact that the angles around point A should add up to 360°.

∠DAB + ∠CAB + ∠CBA = 360°

Given that ∠DAB = 127° and ∠CAB is 60°, you can solve for ∠CBA:

127° + 60° + ∠CBA = 360°

Combine the known angles on the left side:

187° + ∠CBA = 360°

Now, isolate ∠CBA:

∠CBA = 360° - 187°

∠CBA = 173°

so, ∠ACB is 173°.

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.
