Answer:

a) 28 quarters

b) 14 quarters  

Step-by-step explanation:

We are given the following in the question:

Number of quarters = 20 quarters

Number of quarters in room = 40%

Total number of quarter in room =

[tex]=40\%\times (20)\\\\=\dfrac{40}{100}\times 20\\\\=8[/tex]

Thus, the total quarters taken to shopping =

[tex]=20 +40\%\times (20)\\\\=20+8\\=28[/tex]

Thus, 28 quarters were taken to shopping.

Quarter spent on shopping = 50%

Total number of quarter spent in shopping =

[tex]=50\%\times (28)\\\\=\dfrac{50}{100}\times 28\\\\=14[/tex]

Money left =

Money taken for shopping - Money spent

[tex]= 28-14\\=14[/tex]

Thus, we are left with 14 quarters after shopping.

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.

Answer:

[tex](fg)(7) = - 35[/tex]

Step-by-step explanation:

The given functions are:

[tex]f(x) = {x}^{2} - 14[/tex]

and

[tex]g(x) = 6 - x[/tex]

We want to to find

[tex](fg)(7)[/tex]

Note that:

[tex](fg)(x) = f(x) \times g(x)[/tex]

We substitute the functions to obtain:

[tex](fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)[/tex]

We now substitute x=7, to get:

[tex](fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)[/tex]

This implies that

[tex](fg)(7) =( 49-1 4 ) \times (6 - 7)[/tex]

[tex](fg)(7) = 35 \times - 1 = - 35[/tex]

Answer:

$112

Step-by-step explanation:

Answer:

The answer for addition one is 11 1/2. The answer for subtraction would be -5/6.

Hope this helps. Can I please get brainliest if possible?

The answer you are looking for is 11 and 1/2.

To find this answer, you must first add the fractions together. Before you do so, you must make sure they have a common denominator. So, multiply 1/3 by 2/2 to get 2/6. Now, add 2/6 and 1/6 to get 3/6. 3/6 simplified (divided by 3/3) is 1/2.

Next, add the whole numbers. 5 + 6 is 11. Thus making your final answer 11 and 1/2.

Answer: [tex]n=8[/tex]

Cross-multiply

[tex]2/3=n/12[/tex]

[tex](2)*(12)=n*(3)[/tex]

[tex]24=3n[/tex]

Flip the equation

[tex]24=3n---->3n=24[/tex]

Divide both sides by 3

[tex]3n/3=24/3[/tex]

[tex]24/3=8----> n=8[/tex]

Final answer:

To solve the proportion 2/3 = n/12, cross multiply to get 2×12 = 3×n. Simplify the equation to 24 = 3×n, and divide both sides by 3 to get n = 8.

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.

Answer:

231 miles.

Step-by-step explanation:

Tom rented a truck with a base fee of 19.95. You will subtract this from the total since you just want to get the mileage.

Tom is getting charged .85 cents per mile driven.

Tom payed 216.30 subtotal minus the 19.95 base fee since we are trying to only see how many miles he drove.

(216.30-19.95=196.35) This will be total for each mile. All we need to do is divide to get the total of miles

(196.35÷.85= 231)

231 is the number of miles Tom drove.

Step-by-step explanation:

[tex] \frac{2 + 3i}{4 - 5i} [/tex]

[tex] \frac{(2 + 3i)(4 + 5i)}{(4 - 5i)(4 + 5i)} [/tex]

[tex] \frac{8 + 10i + 12i + 15 {i}^{2} }{16 - 25 {i}^{2} } [/tex]

[tex] \frac{8 + 22i + 15( -1 )}{16 - 25 ( - 1)} [/tex]

[tex] \frac{8 - 15 + 22i}{16 + 25} [/tex]

  P(A & B) = 2/7

Answer: 4/7

Step-by-step explanation:

Let [tex]v[/tex] be the usual speed, and [tex]t[/tex] be the usual time.

Following the equation [tex]s=vt[/tex], where s is the space, v is the velocity and t is time, we know that usually we have

[tex]200=vt[/tex]

But this time we were 10mph faster and it took one hour less, so we have

[tex]200=(v+10)(t-1)[/tex]

Since both right hand sides equal 200, they must equal each other:

[tex]vt=(v+10)(t-1)=vt+10t-v-10 \iff 10t-v-10=0 \iff v=10t-10[/tex]

Plug this value in the first equation and we have

[tex]200=vt=(10t-10)t \iff 10t^2-10t-200=0[/tex]

This equation has solutions [tex]t=-4,\quad t=5[/tex]. We can only accept positive solutions, so we have t=5. We finally deduce, again from the first equation,

[tex]200=5v \iff v=\dfrac{200}{5}=40[/tex]

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.

Final answer:

The expression equivalent to (3x²)³ simplifies to 27x⁶, by cubing the coefficient and multiplying the exponent by 3.

Explanation:

The expression equivalent to (3x²)³ is found by cubing the digit term and multiplying the exponent by 3. When we cube 3, we get 3 x 3 x 3 which equals 27. Then, we apply the cubing to the variable term x², by multiplying the exponent 2 by 3, giving us x²ˣ³ or x⁶. Thus, the expression simplifies to 27x⁶.

4.5x-2.3=6.7 (add 2.3 so no number in the equation)

6.7+2.3 is 9

4.5x=9 (divide by 4.5 as it's 9 is divisible by 4.5

9/4.5 is 2

X=2

put it back into the equation

4.5*2 is 9

9-2.3 is 6.7

Therefore X=2

Answer:

x = 2

Step-by-step explanation:

Add 2.3 to both sides.  We get:

4.5x = 6.7 + 2.3 = 9

If 4.5x = 9, then x = 2

The solution to the compound inequality is x > -2 and x < -5, or (-∞, -5) ∪ (-2, ∞).

To find the solution to the compound inequality, we need to solve the individual inequalities separately and then find the intersection of their solution sets.

The solution to the compound inequality is the intersection of the solution sets of the individual inequalities, so the solution is x > -2 and x < -5. To express this in interval notation, we write (-∞, -5) ∪ (-2, ∞).

Answer:

30x^4−12x^3=6x^3(5x−2) = True

4x^2+10x=2x(2x+5) = True

100x^3+5=5x^3(20x+1) = False

8x^3−6x=2x^3(4−3x3) = False

Step-by-step explanation:

The statements which are true are 30x4−12x3=6x3(5x−2) ,  4x2+10x=2x(2x+5)  and  100x3+5=5x3(20x+1)

To determine which of the statements are true, we can simplify each equation and compare.

Option a :

30x4−12x3=6x3(5x−2): Factoring out the common term we can see this equation is true.
Option b:

4x2+10x=2x(2x+5): After simplifying both sides we find that 2x(2x + 5) = 4x2 + 10x, so statement (b) is true.

Option c:

100x3+5=5x3(20x+1): Attempt to simplify this equation as 5x3(20x + 1). Since this simplification holds, statement (c) is also true.

Option d:

8x3−6x=2x3(4−3x3): Simplifying the right side does not give us the left side; thus, statement (d) is false. The correct form would be 2x(4x2 - 3), assuming a typo in exponent notation.

Answer:

1,2,3,4,5,7

Step-by-step explanation:

1+2+3+4+5+7 = 22

Final answer:

Six different natural numbers that add up to 22 are 1, 2, 3, 4, 5, and 7. The process involved starting with the smallest natural numbers and then incrementally adjusting the sequence to arrive at the sum of 22.

Explanation:

The question asks to find six different natural numbers whose sum equals to 22. We can begin with the smallest natural numbers, knowing that 1 cannot be included because the sum of the next five natural numbers (2, 3, 4, 5, and 6) already exceeds 22. If we start with 2 and follow with the next smallest numbers (3, 4, 5, and 6), the sum would be 20, which is close but not quite the target sum. To reach the sum of 22, we need to replace one of these numbers with a slightly larger number while still maintaining the rule that every number must be different.

Let's replace the 6 with a 7, so our numbers are now 2, 3, 4, 5, and 7. If we sum these up (2 + 3 + 4 + 5 + 7), we get 21. We need to add one more number to reach 22. The smallest number we haven't used yet is 1, but adding 1 to our sequence would require us to adjust another number as follows: 1, 2, 3, 4, 5, and 7 add up to 22. Therefore, the six different natural numbers whose sum is 22 are 1, 2, 3, 4, 5, and 7.
