Answer:

26. 30 ≥ 7.5a + 4.5s         28. $22.50

Step-by-step explanation:

26. The family doesn't want to spend over 30 dollars, so when writing the inequality the amount they spend needs to be less than or equal to 30, hence the greater than/equal to sign. When writing the expression a - amount of adults & s - amount of students.

*remember in the question it states middle and high schoolers both count as students

The 7.5 is cost for adults and the 4.5 is cost for students.

28. You can use the expression created in 26

7.5a + 4.5s

Then substitute in the amount of people into their respective categories.

7.5(2) + 4.5(3) = 22.50

Step-by-step explanation:

The correct conversion is 68°F = 20°C.

Conversion is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We are given that;

To convert 68°F

Now,

To solve the formula for C, we need to isolate C on one side of the equation. We can do this by subtracting 32 from both sides and then dividing by 1.8. The steps are:

F = 1.8C + 32

F - 32 = 1.8C

(F - 32) / 1.8 = C

Therefore, the correct formula for C is:

C = (F - 32) / 1.8

To convert 68°F to degrees Celsius, we can plug in F = 68 into the formula and simplify. The steps are:

C = (68 - 32) / 1.8

C = 36 / 1.8

C = 20

Therefore, after conversion the answer will be 68°F = 20°C.

Answer:

90 degrees

Step-by-step explanation:

When we want to find the rotational symmetry of a shape, we will take the total angle measure of most shapes (360 degrees) and divide it by the number of angles that shape has. Since a square has 4 angles, thats what we will divide by and the answer we get will be the smallest angle of rotation.

360 / 4 = 90

Best of Luck!

The smallest angle of rotational symmetry for a square is 90°. A square has four sides of equal length and four angles of 90° each, which means that rotating it by any multiple of 90° will result in the same image. Thus, the smallest angle of rotational symmetry is 90°.

In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:

• Triangle

• Quadrilateral

• Pentagon

• Hexagon

• Heptagon

• Octagon

• Nonagon

Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:

α = 360/n

The smallest angle of rotational symmetry for a square is 90°.

This means that the square can be rotated by 90° and still look the same.

It can also be rotated by 180° and 270° to look the same,

but the smallest angle is 90°.

Answer:

the cost continues to increase

Step-by-step explanation:

the cost (C) approaches infinity (or becomes very large) as t approaches 100%. Thus, the correct answer is: A. The cost continues to increase.

To determine what happens to the cost (C) as t approaches 100%, we can take the limit of the cost function as t approaches 100.

The cost function is given as: [tex]\[ C = \frac{55,000t}{100 - t} \][/tex]

Now, let's find the limit of C as t approaches 100:[tex]\[ \lim_{{t \to 100}} C = \lim_{{t \to 100}} \frac{55,000t}{100 - t} \][/tex]

To find this limit, we can use direct substitution:[tex]\[ \lim_{{t \to 100}} \frac{55,000 \times 100}{100 - 100} = \lim_{{t \to 100}} \frac{5,500,000}{0} \][/tex]

Since the denominator approaches 0 as t approaches 100, the limit is undefined (infinite).

Therefore, the cost (C) approaches infinity (or becomes very large) as t approaches 100%. Thus, the correct answer is: A. The cost continues to increase.

Step-by-step explanation:

Answer:

Step-by-step explanation:

To get equivalent expressions, if you are adding or subtracting, the number and letter you get on the left must be the same as the one on the right.

In B. The answer is incorrect because 4t is minus on the left. The letters are different, so 4t must remain minus. Not B

In C the numbers will combine when you add. If they are the same,, they remain the same. They do not become powers the answer for C is 10s. So C is not correct.

In D you are indicating that 6 is multiplied by 4s.  You can only multiply 6 and 4. They don't add. Not D

A is correct.

Josh starts with 8/8 (or any other fraction that equals 1) of his allowance. He then spends 3/8 of it.

8/8 x 3/8 = 3/8

8/8 - 3/8 = 5/8

He spend 3/8 of his allowance, leaving him with 5/8 left. Then Josh spent 2/3 of that remaining amount.

5/8 x 2/3 = 10/24 = 5/12

Josh has 5/12 of his allowance left for the rest of the week.

There is an error in step 2 where distributive property was not followed.

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Steps taken by the student to solve the formula of the simple interest for the values of '',

Step 1 : A = P( 1 +rt)

Step 2 : A = P + rt

Step 3 : A - p = rt

Step 4 : r = (A - P)/ t

There is an error in step 2 where distributive property was not followed.

Correct steps should be,

Step 1 : A = P( 1 +rt)

Step 2 : A = P + Prt [By distributive property]

Step 3 : A - P = Prt

Step 4 : r = (A-P)/Pt

Therefore, error was made in step 2.
