Answer:

\(r \geqslant - 16\)

Step-by-step explanation:

\( \frac{ - 10 + r}{2} \geqslant - 13\)

multiply both sides by 2:

\( - 10 + r \geqslant - 26\)

add 10 on both sides:

\(r \geqslant - 16\)

Answer:

\(r \ge -16\)

Step-by-step explanation:

To solve any equation/inequality:

1. get the variable to show up exactly once

2. isolate it

\(\frac{-10+r}{2} \ge -13\)

Multiply both sides by 2 and simplify (note that we're multiplying by a positive, not a negative, so the direction of the inequality stays the same, whereas multiplying or dividing by a negative would have changed the direction of the inequality)

\(\frac{-10+r}{2} *2 \ge -13 *2\)

\(-10+r \ge -26\)

Add 10 to both sides, and simplify

\((-10+r)+10 \ge (-26)+10\)

\(r \ge -16\)

Answer:

there are 2.5 gallons in 20 pints of milk, or she drinks 2.5 gallons of milk

Step-by-step explanation:

If she drinks 20 pints of milk, you have to convert by dividing.

1 qt= 2 pints

20/2=10

20 pints = 10 quarts

Then, 1 gal = 4 qts

10/4= 2.5

So, there are 2.5 gallons in 20 pints of milk, or she drinks 2.5 gallons of milk.

Step-by-step explanation:

The sets A and B have the same number of elements, or the same cardinality, according to the notation |A| = |B|. The sets do not necessarily have to be equal or share any elements, however, for this to be the case.

We can declare the following for the given sets E, O, and P:

a. [P n 0| < |Z|: This assertion is untrue. The cardinality of P must be smaller than or equal to the cardinality of Z since the set P of prime numbers is a subset of the set Z of all integers.

b. [E] JOU EU: This assertion is false. JOU EU is not a recognised mathematical notation.

c. [P n E| |ZI: This assertion is false. The set of even prime numbers, which is represented by the notation [P n E|, would be the cardinality of the intersection of the sets P and E. The cardinality of this set must be less than or equal to the cardinality of both P and E as it is a subset of both.

d. [PU E| = |Z|: This assertion is untrue. The set of all numbers that are either prime or even is represented by the notation [PU E|], which stands for the cardinality of the union of the sets P and E. The cardinality of this set, which is a superset of both P and E, must be greater than or equal to the cardinality of both sets.

Note that the full question is:

The notation |A| = |B| meansthat |A| = |B] and [A] + [B]. Let E be the set of even integers, O the set of odd integers and P the set of prime numbers. Then: Select one or more:

a. [P n 0| < |Z|

b. [E] < JOU EU

c. [P n E| < |ZI

d. [PU E| = |Z|

Answer:

5/17

Step-by-step explanation:

This is a question to calculate probability from odds. The formula is given as:

A formula for calculating probability from odds is P = Odds / (Odds + 1)

From the question , we are told that the odds of receiving a gift is

= 5:12

The probability of Jessica receiving a gift =

Probability = Odds / (Odds + 1)

P = 5/12 / ( 5/12 + 1)

P = (5/12)/ (17/12)

P = 5/12 × 12/17

= 5/17

Therefore, the probability of Jessica. receiving a gift is 5/17.

To calculate the total surface area of a triangular prism, we need to find the area of each face and add them up.

The triangular faces have base 5cm and height 12cm, so each one has an area of:

(1/2) x 5cm x 12cm = 30cm²

There are two of these faces, so their combined area is:

2 x 30cm² = 60cm²

The rectangular faces have dimensions 5cm x 10cm and 5cm x 13cm, so their areas are:

5cm x 10cm = 50cm²

5cm x 13cm = 65cm²

Again, there are two of these faces, so their combined area is:

2 x (50cm² + 65cm²) = 230cm²

Finally, we add up the areas of all the faces to get the total surface area:

60cm² + 230cm² = 290cm²

Therefore, the total surface area of this triangular prism is 290cm².

Julio accidentally put in an extra 1/10 cup of sugar.

To calculate the number of extra cups of sugar that Julio put in, we need to find the difference between what the recipe called for (3/10 cups) and what he actually added (4/10 cups).

The difference can be calculated as follows:

Actual amount - Required amount = Extra amount

= 4/10 - 3/10

= 1/10

Therefore, Julio accidentally put in an extra 1/10 cup of sugar.

The equation of the line in slope intercept form is y = -5x - 40.

The equation of a line can be represented in slope intercept form as follows:

where

Therefore,  the line that passes through (-7,-5) and it's parallel to  y = -5x + 1.

Hence, parallel line have the same slopes.

Therefore,

y = -5x + b

Answer:

Step-by-step explanation:

y = mx+c

m is the slope

c is the y-intercept

compare the below equations:

The measure of the minor arc m∡rv = 111°

Recall that according to the principle of angle of intersecting secants, (a-b)/2 = c

Where a = ∡RV
b = ∡SU = 37°:

and c = ∠T (the angle between intersecting secants.

Thus, if (a-b)/2 = c, and b = c = 37 degrees, then we can substitute these values into the equation to get:

(a - 37) / 2 = 37

Multiplying both sides by 2 gives:

a - 37 = 74

Adding 37 to both sides gives:

a = 111

The two expressions are not equivalent.

To simplify the expression (p^2n^1/2)^0 √ p^5n^4, we first need to understand the properties of exponents and radicals.

Recall that any number raised to the power of zero is equal to 1, so (p^2n^1/2)^0 = 1.

Next, we can simplify the radical term by multiplying the exponents inside and outside the radical:

√ p^5n^4 =

(p^5n^4)^(1/2)

= p^(5/2)n^(4/2)

= p^(5/2)n^2

Combining this result with the previous step, we have:

(p^2n^1/2)^0 √ p^5n^4

= 1 * p^(5/2)n^2

= p^(5/2)n^2

The total cost of rents is $180.

In the given table,

The cost of skis per day  = $48

The cost of pole per day = $12

Now since given that,

Alveres rents for 3 days

Therefore,

The cost of skis for 3 days  = $48 x 3

                                             =  $144

The cost of pole for 3 days = $12 x 3

                                             = $36

To find the total cost of rental,

Adding the cost of 3 days of skis and cost of 3 days of poles,
