The real-world problem involves maintaining a minimum safe temperature in an animal shelter that can be represented by the inequality r + 32 ≥ 56, which simplifies to r ≥ 24 after subtracting 32 from both sides.

Consider a situation where r represents the room temperature in degrees Fahrenheit without accounting for wind chill or humidity, and the inequality r + 32 ≥ 56 represents the minimum safe temperature that must be maintained in an animal shelter to keep the animals comfortable during winter months.

To solve the inequality for r, we would subtract 32 from both sides:

So, the shelter must keep the room temperature at 24 degrees Fahrenheit or higher to ensure the animals' safety.

If we were to compare this with mathematical rules presented in LibreTexts, subtracting the same number from both sides of an inequality does not change the relationship, which is a standard procedure for solving inequalities.

To represent the number of gallons of water in the tub after x minutes, the equation y = 30 - 6x can be used.

The question asks us to write an equation that represents the number of gallons of water in the tub after a certain number of minutes. Let's break down the information given:

We can use this information to find the rate at which the bathtub is draining. To do this, we'll subtract the amount of water after 5 minutes from the amount after 2 minutes to get the change in water: 30 gallons - 12 gallons = 18 gallons. This means the tub is draining 18 gallons over a span of 3 minutes, which is equivalent to a rate of 6 gallons per minute.

Now, we can write the equation that represents the number of gallons of water in the tub after x minutes. Let y represent the number of gallons, and x represent the number of minutes. We can use the equation y = 30 - 6x, where 30 is the initial amount of water in the tub at 2 minutes, and 6x is the amount of water drained over x minutes at a rate of 6 gallons per minute.

The factored form of the expression 16a + 10 is 2(8a + 5).

To factor the expression 16a + 10, we can divide each term by the greatest common factor (GCF) of the expression.

The GCF of 16a and 10 is 2, so we can divide each term by 2 to get:

16a + 10 = 2(8a + 5)

Therefore, the factored form of the expression 16a + 10 is 2(8a + 5).

Answer : The ratio represents the number of votes for hot dogs to chicken is, [tex]\frac{2}{5}[/tex]

Step-by-step explanation : Given,

Number of members voted for pizza = 6

Number of members voted for chicken = 10

Number of members voted for hot dogs = 20 - (10 +6) = 4

Now we have to determine the ratio represents the number of votes for hot dogs to chicken.

[tex]\frac{\text{Number of members voted for hot dogs}}{\text{Number of members voted for chicken}}=\frac{4}{10}[/tex]

[tex]\frac{\text{Number of members voted for hot dogs}}{\text{Number of members voted for chicken}}=\frac{2}{5}[/tex]

Thus, the ratio represents the number of votes for hot dogs to chicken is, [tex]\frac{2}{5}[/tex]

Answer:

To sum 37+58 mentally, we could first sum 30+50=80 and then sum the units, 80+7+8= 95.

But, if we have to show properties, we could separate first the numbers:

30 + 7 + 50 + 8.

Then, we apply commutative property to position like numbers aside:

30+50+7+8

Then, we apply associate property, to have a better order of the operation, which is easier to the mind:

(30+50) + (7+8)

Then, we sum each group:

80 + 15

At last, we sum again and have the result:

80+15=95.

To maintain an equivalent ratio of sugar to milk when increasing a recipe, multiply both the sugar and milk amounts by the same factor. For example, multiplying by 5 results in a ratio of 15 tablespoons of sugar to 10 tablespoons of milk.

If Mark is using a ratio of 3 tablespoons of sugar to 2 tablespoons of milk in a recipe and decides to increase the recipe, we need to maintain the same ratio for any quantity. An equivalent ratio can be found by multiplying both parts of the original ratio by the same number. For example, if Mark wanted to double the recipe, he would use 6 tablespoons of sugar and 4 tablespoons of milk (3 x 2 = 6 and 2 x 2 = 4), keeping the same ratio of 3:2.

To increase the recipe to any desired amount, Mark could use a conversion factor. For instance, if the original recipe makes 1 batch and Mark wants to make 5 batches, he multiplies both parts of the ratio by 5. The new ratio would be 15 tablespoons of sugar to 10 tablespoons of milk, as 3 x 5 = 15 and 2 x 5 = 10. This maintains the sweetness and consistency of the recipe across a larger volume.

The product of the missing number (4,230) is 2,115,000

Therefore let the missing number be X

Hence,

X = 42300 ÷ 10

X = 42300 / 10

X = 4,230

Therefore the missing number is 4230.

Recall, we are to find the product 4230 and 500. This process require that we multiply 4230 and 500.

Therefore, let the product of 4,230 and 500 be P

P = 4230 x 500

P = 2,115,000

Hence, the product of the missing number (4230) and 500 is 2,115,000.

The above math problem deals with numbers, and was solved with the aid of division and multiplication, which are functions of an order of operations known as BODMAS.  

Division deals with splitting or dividing numerical values into different equal parts or groups. Multiplication on its part is the repeated adding of several numbers to derive a final numerical value.

Victoria would have paid $4.25 for 8.5 pounds of carrots if they were $0.50 less per pound.

To find out how much Victoria would have paid for 8.5 pounds of carrots if they were $0.50 less per pound, we need to subtract $0.50 from the original price per pound and then multiply it by 8.5.

Let's say the original price per pound of carrots is $1.00. Subtracting $0.50 from it gives us $0.50. Multiplying $0.50 by 8.5 gives us $4.25.

Therefore, Victoria would have paid $4.25 for 8.5 pounds of carrots if they were $0.50 less per pound.

Final answer:

Michelle used 70 beads to make her 14-inch long necklace, as determined by solving the equation 1/7b + 4 = 14 and isolating the variable b.

Explanation:

The question asks us to solve for the number of beads, b, in a necklace that is 14 inches long. The equation given is 1/7b + 4 = 14. We need to solve for b.

To solve for b, we first subtract 4 from both sides of the equation to get 1/7b = 10. Next, we multiply both sides by 7 to isolate b on one side of the equation, which gives us b = 70. Therefore, Michelle used 70 beads for her necklace.
