1st blank: Multiply

2nd blank: 4 quarts per cup

3rd blank: 16 cups

4th blank: Multiply

5th blank: 16 cups per gallon  

6th blank: 48 cups.

Step-by-step explanation:

We have been given that Elyse needs 3 gallons of water to mix a fruit drink, but she has a 1-cup measuring cup. She knows that there are 4 cups in 1 quart, and 4 quarts in 1 gallon.

Elyse can use the unit rate. First she can multiply 4 cups in a quart by 4 quarts per gallon to find that there are 16 cups in 1 gallon. She can then multiply 3 gallons by 16 cups per gallon to determine that she will need 48 cups of water to mix the fruit drink.

[tex]\frac{\text{4 cups}}{\text{Quart}}\times\frac{\text{4 quarts}}{\text{gallon}}=\frac{\text{16 cups}}{\text{gallon}}[/tex]

Step 2:

[tex]3\text{ gallons}\times\frac{\text{16 cups}}{\text{gallon}}=3\times \text{16 cups}=\text{48 cups}[/tex]

The fraction of the wall that is concrete is obtained by dividing the width of concrete (12 inches) by the total wall width (26 inches). This gives a fraction of 12/26, which simplifies to 6/13. Therefore, 6/13 of the wall is made of concrete.

To solve this problem, we can express the width of the concrete part of the wall as a fraction of the total wall width. First, we will identify the total width of the wall, which includes the different sections of concrete, brick, and limestone. In this case, that is 26 inches (12 inches of concrete + 9 inches of brick + 5 inches of limestone = 26 inches).

Next, we need to determine the width of the concrete section, which is 12 inches.

To express the width of the concrete wall as a fraction of the total wall width, we divide the width of the concrete part by the total wall width. So, we have: 12 inches / 26 inches. Therefore, the fraction of the wall that is concrete is 12/26, which simplifies to 6/13. Out of every 13 parts of the wall, 6 parts are made up of concrete.

Answer:

C) Graph B

Step-by-step explanation:

All of these equations have the line y = -2x - 2 graphed.

In the inequality, we have the symbol greater than or equal to.  This tells us the line drawn must be solid, not dashed.  This means the correct graph is either B or D.

Since it is greater than or equal to, the shaded area must be above the line.  This is graph B.

We need to therefore plot the graph passing through the coordinate point (0, -2) and (-1, 0). Option B is correct

Inequality are expression not separated y an equal sign. For an inequality, the upper graph is shaded for greater than and the lower part shaded for less than sign.

Since the sign is greater than and equal to, hence the line will be a solid line as shown in the graph.

Given the inequality y≥ -2x -2. Find the intercepts

If x = 0

y = -2(0) - 2

y = -2

The y-intercept is at (0,-2

If y = 0

0 = -2x - 2

2x = -2

x = -1

The x-intercept is at (-1,0)

We need to therefore plot the graph passing through the coordinate point (0, -2) and (-1, 0) as shown

Counterexample: 4-5=-1

they are both positive but the sum is a negative

-Hope it helps!

A counterexample that makes the conclusion false is when the two positive numbers have a difference of zero.

A counterexample that makes the conclusion false is when the two positive numbers have a difference of zero. For example, if we take the numbers 5 and 5, their difference is 0, which is not positive. So this counterexample shows that the conclusion 'the difference of two positive numbers is always positive' is false. The counterexample to the conclusion that "the difference of two positive numbers is always positive" is:

1 - 3 = -2

In this case, you have two positive numbers (1 and 3), but their difference (-2) is negative, not positive. This counterexample demonstrates that the statement is not always true, as there are situations where the difference of two positive numbers can be negative.

52mph

To make the 312-mile road trip in 6 hours, Rosie would need to drive at a constant rate of 52 miles per hour.

To find the constant rate at which Rosie needs to drive, we can divide the total distance by the total time. In this case, Rosie needs to drive 312 miles in 6 hours. So the rate would be 312 miles ÷ 6 hours = 52 miles per hour.

To find the total mass of the four cars, first convert the mass given in kilograms to tonnes, and then sum all the masses. The total mass of the cars on the car transporter is 10.3 tonnes.

The total mass of the four cars loaded on a car transporter can be calculated by first ensuring all the masses are in the same unit. The masses are given as 2.1 tonnes, 3.7 tonnes, 2.8 tonnes, and 1700 kg. We must convert the mass given in kilograms to tonnes before we add them together, as there are 1000 kg in a tonne.

To convert 1700 kg to tonnes:

Now that all masses are in tonnes, we sum them up:

Total mass in tonnes = 2.1 + 3.7 + 2.8 + 1.7 = 10.3 tonnes.

Therefore, the total mass of the four cars on the car transporter is 10.3 tonnes.

the correct inequality is: m ≥ 8 + 4

The given information states that Demarcus has at least $8 more than his older sister, who has $4.

To find how much money Demarcus has, we denote m as the amount of money Demarcus has.

Since Demarcus has at least $8 more than his older sister, we can express this relationship as:

m ≥ 8 + 4

This inequality states that Demarcus's money m is greater than or equal to the sum of $8 (more than his sister) and $4 (his sister's money).

So, the correct inequality is: m ≥ 8 + 4

Therefore, the option is: m ≥ 8 + 4

The probable question maybe:

Demarcus has at least $8 more than his older sister. His older sister has $4.

Which of the following inequalities could be used to find how much money, m. Demarcus has?

Let the first number be = x

Then other number according to question is

4 less than 5 times the number i.e. 5x-4

Also ,sum of numbers is 32

x+5x-4=32

6x-4=32

Add 4 to both sides

6x-4+4=32+4

6x=36

Divide both sides by 6

x=36/6

x=6

First number =x =6

Other number =5(6)-4 = 30-4 =26

Answer: 26 and 6

Step-by-step explanation: Let's use two variables to represent our two numbers in this problem. Since a variable is a letter that represents any number, we can pick any letters we want to but I will use with x and y.

So if the sum of two numbers is 32, that means x + y = 32.

To solve for two separate variables, we will need two separate equations. So for the second equation, let's read through the second sentence in the problem.

"One of the numbers" that's x, "is" means equals, "4 less than 5 times the other" is not 4 - 3y, it means 5y - 4. The word "less than" switches the order around. So we now have x = 5y - 4.

So to solve this system of equations, let's use substitution. Since x = 5y - 4, we can substitute a 5y - 4 in for x in the first equation to get (5y - 4) + y = 32. Solving from here we get 6y - 4 = 32 by combining like terms. Now we can get rid of that -4 by adding 4 to both sides of the equation to get 6y = 36. Now, we will divide both sides of the equation by 6 in order to isolate y and we end up with y = 6.

To find x, plug 6 back in for y in the second equation to get x = 5 (6) -4 which we can simplify to x = 30 - 4 which simplifies to x = 26.

Therefore, our two numbers in this problem are 26 and 6.

4 3/8 because 1 2/3 and 2 5/8 multiplied together is that.

change each to an improper fraction

1 2/3 = (3*1+2)/3 = 5/3

2 5/8 = (8*2+5)/8 = 21/8

5/3 * 21/8  = 105/24

divide by 3

35/8

4*8 = 32  35-32 = 3

4 3/8

Total length of ribbon lucy has=4 inches

She wants to divide it into 6 equal sized pieces so  

Length of each piece=4/6

This can also be written as:

Length of each piece=4*(1/6 )

Now we will look at the options one by one:

For A, Each piece has 6/4 inches of ribbon.. This statement is not true as we have to divide 4 inches into 6 pieces so 4 is supposed to be in the numerator.

For B, breaking down 4/6 gives us 4*(1/6), so the statement is not true.

For C , as we can see that the expression is 4*(1/6), each piece will have 1/6 of inches of ribbon.

The value of the sauna fee is $ 15, while each visit to the gym is worth $ 8.25.

Since Jeffrey purchased a card for $ 180 that gives him 20 visits to a new gym and includes a one-time fee for unlimited use of the sauna, and after 5 visits, Jeff has $ 123.75 left on the card, and after 11 visits, he has $ 74.25 left on the card, to determine an equation that Jeffrey can use to determine the cost of each visit and the fee for the sauna use the following calculation must be performed:

The difference between the remaining sum after 5 visits and 11 visits should be obtained, and then divided by 6 to obtain the value of a visit to the gym. Then, you must multiply this result by 20, and subtract the result from the initial value of 180 to know the value of the sauna fee.

Therefore, the value of the sauna fee is $ 15, while each visit to the gym is worth $ 8.25.
