Answer: See explanation

Step-by-step explanation:

The normal cost of the book plus the sales tax will be:

= $28.50 + ($28.50 × 10%)

= $28.50 + ($28.50 × 0.1)

= $28.50 + $2.85

= $31.35

Since there's a discount of 35%, the amount they'll have to pay will be:

= $31.35 - ($31.35 × 35%)

= $31.35 - ($31.35 × 0.35)

= $31.35 - $10.9725

= $20.3775

They do not have enough money to make the purchase.

Alfred takes 35% of $28.50 and subtracts that amount from the normal price. Alfred's calculation is shown below:

= $28.50 - (35% of $28.50)

= $28.50 - (0.35 × $28.50)

= $28.50 - $9.975

= $18.525

He takes 10% of the discounted selling price and adds it back to find the purchase amount. This will be:

= $18.525 + (10% × $18.525)

= $18.525 + $1.8525

= $20.3775

Alfred is correct

Larissa takes 65% of the normal purchase price and then computes 110% of the reduced price. This will be:

= 65% × $28.50

= 0.65 × $28.50

= $18.525

= 110% × $18.525

= 1.1 × $18.525

= $20.3775

Larisa is also correct

Answer:

The probability is 2/5

Step-by-step explanation:

Here, we want to calculate the probability that the first person will sit in a yellow roller coaster car

The number of cars to select from is 6 + 9 = 15 cars

The number of yellow cars is 6

So the probability that the first person selects a yellow roller coaster car to seat is 6/15 = 2/5

Answer:

15 blankets

Step-by-step explanation:

Debora plans to sew 3 blankets for each of her nieces. If she has 5 nieces, that means she will sew 3 blankets for each of them.

Number of blankets Debora sews = 3 blankets × 5 nieces

= 15 blankets

Therefore, Debora will sew 15 blankets in total.

Answer:

In cooking (recipes).

Step-by-step explanation:

If the serving size for a recipe is not adequate for the number of people you are serving, you will have to convert the amounts(measurements) of the ingredients to suit your needs. You will do this by first creating a ratio defining the relationship between the serving size of the given recipe to the number of people needed to be served. For example, if a recipe serves 4 people, and you need to serve 8, your ratio would simplify to 1/2. This means you must proportionally relate this ratio to the individual amounts of each ingredient.

Answer:

Area of the base is 10.5 cm².

Step-by-step explanation:

Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases

Vertical height = 6 cm

Volume = 63 cm³

From the formula,

63 = Area of the triangular base × 6

Area of the base = [tex]\frac{63}{6}[/tex]

                            = 10.5 cm²

Therefore, area of the base is 10.5 cm².

Answer:

Approximately 78 yards

Step-by-step explanation:

From the question, I was able to deduce that the swimming pool is a cuboid because the length and width step different in yards. After sketching a cuboid, length= 60 yards, width= 50 yards, then draw a diagonal across the upper rectangle of the cuboid, to get the diagonal, use Pythagoras theorem, Hypotenuse²= opposite²+adjacent²;. x²=60²+50²=3600+2500=6100 ;.

x²=6100 therefore X=√6100 =78.1024 yards, but approximately 78yards, since the question instructed that answer should be approximated.

Answer:

[tex]\huge\boxed{\sf Star = 14}[/tex]

Step-by-step explanation:

Let snowman be x , star be y and shopping bag be z.

So, the given equations are:

1) x + y = 20                 (Eq. 1)

2) z = x + x      

 z = 2x                         (Eq. 2)

3) z + x = 18                   (Eq. 3)

Put Eq. (2) in Eq. (3)

2x + x = 18

3x = 18

Divide both sides by 3

x = 18 / 3

x = snowman = 6

Now, Put x in (Eq. 1)

6 + y = 20

Subtract 6 to both sides

y = 20 - 6

y = 14

So,

Star = 14

Answer:

The distance would be (5,-3)

Step-by-step explanation:

A: X=4

Step 1: Distribute the 7 within the parenthesis which will give you:

7x - 21 = 7

Step 2: Add over the -21 to the other side of the = which will give you:

7x = 28

Step 3: Divide by 7 on both sides to get the final answer, X=4

B: M=9

Step 1: Multiply by 4 on both sides, to cancel it out on the right, which will give you:

32 = 3m + 5

Step 2: Subtract the 5 from each side, giving you:

27 = 3m

Step 3: Divide by 3 on both sides to get the final answer, M=9

C: X=28

Step 1: Subtract 9 from both sides, giving you:

x/2 = 14

Step 2: Multiply by 2 on both sides to give you:

x = 28  (This will be our final answer, there is nothing left to simplify.)

D: X=3

Step 1: Distribute the 2 on the left and the (-) on the right to give you:

5 + 2x + 10 = 10 - 4 + 5x

Step 2: Combine like terms and simplify to give you:

15 + 2x = 6 + 5x

Step 3: Subtract over the (2x) to give you:

15 = 6 + 3x

Step 4: Subtract over the 6 to give you:

9 = 3x

Step 5: Divide by 3 on both sides to get the final answer, X=3

Answer:

5 Remainder 2

Answer:

The answer is 5 remainder 2

Step-by-step explanation:

The remainder theorem says that a polynomial f(x) has a remainder of f(c) upon getting divided by x - c. So if

f(x) = x⁴ + p x³ + q x² + r x + 6

is divisible by x - 1, x - 2, and x - 3, then we have

f (1) = 7 + p + q + r = 0

f (2) = 22 + 8p + 4q + 2r = 0

f (3) = 87 + 27p + 9q + 3r = 0

Solve the system for p, q, r. You can eliminate r by substituting the first equation into the other two:

p + q + r = -7

8p + 4q + 2r = -22   →   6p + 2q - 14 = -22   →   3p + q = -4

27p + 9q + 3r = -87   →   24p + 6q - 21 = -87   →   4p + q = -11

Eliminate q by adding (-1) times the first equation to the second one, then solve for p :

- (3p + q) + (4p + q) = - (-4) + (-11)

-3p - q + 4p + q = 4 - 11

p = -7

Solve for q :

3p + q = -4   →   3 (-7) + q = -4   →   q = 17

Solve for r :

p + q + r = -7   →   -7 + 17 + r = -7   →   r = -17

Answer:

x=14

Step-by-step explanation:

Solving the equation x - 10 = 4, the value of x, which is the solution is calculated as x = 14.

Solving an equation simply involves determining the value of the variable in the equation, which is the unknown.

For example, we are asked to solve the equation, x - 10 = 4., what it simply means is that we need to determine what the value of x is in the equation that will make it true. Do the following:

x - 10 = 4

x - 10 + 10 = 4+ 10 [addition property of equality]

x = 14

Therefore, the solution of the equation is x = 14.

Answer:

There are 41 dimes and 26 nickels.

Step-by-step explanation:

From the information given, you know that you have 67 coins which would be:

x+y=67

Also, you now that the value of each coin is:

dimes= $0.10

nickels=$0.05

With this you can say that the number of dimes for its value plus the number of nickels for its value is equal to $5.40:

0.10x+0.05y=5.40

You will have the following equations:

x+y=67 (1)

0.10x+0.05y=5.40 (2), where:

x are the number of dimes

y are the number of nickels

First, you can solve for x in (1):

x=67-y

Then, you can replace (3) in (2):

0.10(67-y)+0.05y=5.40

6.7-0.10y+0.05y=5.40

1.3=0.05y

y=1.3/0.05

y=26

Now, you can replace the value of y in (3) to find x:

x=67-y

x=67-26

x=41

According to this, the answer is that there are 41 dimes and 26 nickels.
