Answer:

Rafael gets $4,32 In tips. The old lady gets $41.68 in change.

Step-by-step explanation:

Step 1: To calculate the tip we must take into account that it is 8% of the total amount of the bill.

$54 * 8%/100% = $4,32

Rafael gets $4,32 In tips.

Step 2: Now we must calculate the change the old lady receives. For this, we must subtract from the $100 that she gives the part corresponding to the payment for food and the part corresponding to the tip.

$100 - $54 - $4,32 = $41,68

The old lady gets $41.68 in change.

Answer:

a. [tex]\frac{2}{5}[/tex] yard

b. 1.2 feet

Step-by-step explanation:

a. Jackie cut a 2-yard spool into 5 equal length of ribbon.

We will divide 2 yard by 5 = 2 ÷ 5 =  [tex]\frac{2}{5}[/tex] yard

5 units = 2 yard

1 unit = [tex]\frac{2}{5}[/tex] yard

Check : [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{10}{5}[/tex] = 2

b. Length of each ribbon in feet

Since 1 yard = 3 feet

therefore, 2 yard = 3 × 2 = 6 feet

6 feet in to 5 equal part = 6 ÷ 5

                                       = 1.2 feet

check :   1.2 + 1.2 + 1.2 + 1.2 + 1.2 = 6.0 feet

Each ribbon cut from a 2-yard spool into 5 equal parts will be 0.4 yards or 1.2 feet in length. Tape diagrams represent this division into equal parts.

To determine the length of each ribbon when a 2-yard spool is cut into 5 equal lengths, you need to divide the total length by the number of pieces.

To represent this with a tape diagram, imagine a line equally divided into 5 sections, with each section representing 0.4 yards.

For the length in feet, since 1 yard equals 3 feet, we multiply the length in yards by 3.

To show this with a tape diagram, you can divide a line into 5 sections with each section representing 1.2 feet.

Answer:

75 and 79

Step-by-step explanation:

An integer is any whole number. So you can  use practically any combination of numbers as long as one is greater than 77 and one is lower than 77.

So an example would be, 79 and 75

By setting up the question as an algebraic equation, 1/2 * x = 21, and solving for x, it's determined that half of 42 is equal to 21.

The question we're looking to solve is: "1/2 of what number is 7 times 3?" First, let's understand that 7 times 3 equals 21. The question asks which number, when halved, gives us 21. This can easily be set up as an algebraic equation: 1/2 * x = 21, where x represents the number we're trying to find.

To solve for x, we first multiply both sides of the equation by 2 to get rid of the fraction (1/2). This leaves us with: x = 21 * 2. Therefore, x = 42. The number, when cut in half, that results in 21, is 42.

Answer:

D. 16.8

Step-by-step explanation:

It is right trust me!!!

Answer:

Additional amount of clearance between the truck and overpass is 16.8 inches.

Step-by-step explanation:

A law states that a a freight truck must have the clearance of at least 3 feet to travel under the a overpass.

Sign on an overpass states that the overpass is 18 feet above the road's surface.

Height of the truck is 13.6 feet.

As per rule height of overpass from the road must be height of the truck + clearance.

Additional amount of clearance between the truck and the overpass

= Distance between the road and the overpass - (height of the truck + clearance)

= 18 - (13.6 + 3)

= 18 - 16.6

= 1.4 feet

Since 1.4 feet = 12 inches

1.4 feet = 12×1.4 = 16.8 inches

Therefore, additional amount of clearance between the truck and overpass is 16.8 inches.

Answer:

120 ml

Step-by-step explanation:

Let x ml of 5% acid should mix with 60 milliliters of 20% acid to obtain a 10% solution,

Thus, the quantity of resultant mixture = ( x + 60 ) ml,

Also,

Acid in x ml 5% acid + Acid in x ml 5% acid = acid in 10% resultant solution,

5% of x + 20% of 60 = 10% of ( x + 60)

[tex]\frac{5x}{100}+\frac{20\times 60}{100}=\frac{10\times (x+60)}{100}[/tex]

[tex]5x + 1200 = 10x + 600[/tex]

[tex]5x - 10x = 600 - 1200[/tex]

[tex]-5x = -600[/tex]

[tex]\implies x = \frac{-600}{-5}=120[/tex]

Hence, 120 ml of 5% acid should be mixed.

Answer:

5,500,000 = (5 x 100000000) + (0 x 10000000) + (5 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)

Step-by-step explanation:

The expanded form of 5,500,000 is  (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousands,and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.

Now the given number is,

5,500,000

Now each digit place value is given as,

5 =  (5 x 1000000)  

5 =  (5 x 100000)

0 =  (0 x 10000)

0 =  (0 x 1000)  

0 =  (0 x 100)

0 =  (0 x 10)

0 =  (0 x 1)

Adding this together, we get

5,500,000 = (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

Hence, The expanded form of 5,500,000 is  (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

Option C.

Step-by-step explanation:

Let x be the distance from holes center in feet and y be the depth from level ground in feet.

The given table represents a quadratic functions.

x :    -2             0           2

y :    -6            -8          -6

The depth from level ground in feet is same at x=-2 and x=2 it means the hole is symmetric about the line x=0.

The value of a quadratic function is on its extreme at line of symmetry.

In the given function the line of symmetry is x=0. So, the depth of the hole is defined on x=0.

From the table it is clear that at x=0 the depth from level ground is 8 feet.

Therefore, the correct option is C.

Answer:

Two thirds of the Senate must approve it

The minimum number of Senate members needed to approve a treaty is two-thirds of the Senate.

The minimum number of members of the Senate that must approve a treaty for it to go into effect is two-thirds (⅔) of the Senate. The Constitution of the United States, Article II, Section 2, Clause 2 states that the President has the power to make treaties, but they require the advice and consent of the Senate.

For example, if the Senate has 100 members, then 67 votes would be needed to approve a treaty for it to go into effect. However, it is important to note that the Senate may require a supermajority vote, which would mean a higher percentage of approval than two-thirds, depending on their rules and procedures.

Answer:22/7

Step-by-step explanation:

Final answer:

The three consecutive integers that satisfy the condition are 11, 12, and 13. These numbers are such that the sum of the first two is equal to the third integer plus 10.

Explanation:

The question asks to find three consecutive integers where the sum of the first two is 10 more than the third. To solve this, let's call the smallest integer 'x'. Therefore, the next two consecutive integers will be 'x+1' and 'x+2'. The problem states that the sum of the first two integers is 10 more than the third, which gives us the equation: x + (x + 1) = (x + 2) + 10.

Simplifying this equation gives us 2x + 1 = x + 12. To find the value of 'x', we subtract 'x' from both sides of the equation, which gives us x + 1 = 12. Next, we subtract 1 from both sides to get x = 11. The three consecutive integers in question are therefore 11, 12, and 13.

Checking our work: the sum of the first two integers is 11 + 12 = 23. The third integer plus 10 is 13 + 10 = 23. Since both sums are equal, our solution is correct.

Final answer:

To find three consecutive integers, let the first integer be x, the second integer be x+1, and the third integer be x+2. Solve the equation x + (x+1) = (x+2) + 10 to find x, then determine the three consecutive integers.

Explanation:

To find three consecutive integers, we can let the first integer be x, the second integer be x+1, and the third integer be x+2. We are given that the sum of the first two integers is 10 more than the third integer. This can be written as:

x + (x+1) = (x+2) + 10

Combining like terms and solving the equation, we get:

2x + 1 = x + 12

x = 11

So the three consecutive integers are 11, 12, and 13.

To find the original price of the item that was reduced by 20% to $126.40, divide the sale price by 0.80, which yields an original price of $158.00.

To determine the original price of an item that has been marked 20% off, we need to work backward from the sale price. The sale price represents 80% of the original price because 100% - 20% = 80%.

The question is provided with the reduced price which is $126.40. To find the original price, we divide the reduced price by 0.80.
