The largest perfect square less than or equal to 45 is 36, which is the square of 6. Squaring numbers less than 7 shows that 36 is the perfect square closest to, but not exceeding 45.

Answer:

True  

Step-by-step explanation:

Given : Statement - 'A degree is larger than 30 arc minutes'.

To find : True or False ?

Solution :

We know that,

1 degree is [tex]1^\circ=\frac{1}{360}[/tex] of a circle

1 arc minute is [tex]1^'=(\frac{1}{60})^\circ[/tex] of degree.

So, 30 arc minutes is [tex]30^'=(\frac{30}{60})^\circ[/tex] of degree.

30 arc minutes is [tex]30^'=(\frac{1}{2})^\circ[/tex] of degree.

Which clearly means,

[tex]1^\circ>(\frac{1}{2})^\circ[/tex]

[tex]1^\circ>30^'[/tex]

Therefore, The given statement is true.

'A degree is larger than 30 arc minutes'.

Use the chain rule of differentiation to calculate ∂z/∂s and ∂z/∂t. Start by differentiating the functions z with respect to x and y, then differentiate the functions x and y with respect to s and t. Finally, plug the derived values into the chain rule formula to get the expressions for ∂z/∂s and ∂z/∂t.

To solve the problem, we will need to apply the chain rule in order to calculate ∂z/∂s and ∂z/∂t. The chain rule is used in calculus to differentiate a function that has other functions inside of it.

We will differentiate z which is the function of x and y, and x and y themselves are functions of s and t.

The steps are as follows:

The chain rule formula is:

∂z/∂s = ∂z/∂x * ∂x/∂s + ∂z/∂y * ∂y/∂s

and

∂z/∂t = ∂z/∂x * ∂x/∂t + ∂z/∂y * ∂y/∂t.

This will give you the final expressions for ∂z/∂s and ∂z/∂t as functions of x, y, s, t.

To determine the odds in favor of winning $5 or more at the carnival, we need to consider the number of tickets that win $5 or more and the total number of tickets.

Identify the tickets that win $5 or more: Yellow tickets win $5 and Blue tickets win $10.

Count the number of these tickets:

Yellow tickets: 25

Blue tickets: 5

Total tickets that win $5 or more:

25 + 5  = 30

Total number of tickets:

100 + 25 + 5 = 130

Odds in favor of winning $5 or more is the ratio of favorable outcomes to unfavorable outcomes:

Winning tickets: 30

Non-winning tickets:

130 - 30 = 100

Simplified odds:

30 to 100 = 3 to 10

Therefore, the odds in favor of winning $5 or more are 3 to 10.

The odds in favor of winning $5 or more in a carnival drawing are 3 : 10. So, the correct option is (B).

To determine the odds in favor of winning $5 or more in a carnival drawing, observe the number of tickets for each prize and calculate the favorable outcomes.

Here are the ticket counts:

⇒ 100 (green) + 25 (yellow) + 5 (blue) = 130 tickets

⇒ 25 (yellow) + 5 (blue) = 30 tickets

⇒ 130 (total) - 30 = 100 tickets

The correct answer is: Option (D) x = 72°

Explanation:

When two lines are crossed by another line, the angles in matching corners are called corresponding angles. When the two lines are parallel, the corresponding angles are equal.

Here in this case, the two lines are "AB" and "CD", and both are parallel and are crossed by the line; therefore, the corresponding angles will be the same.

Since the first corresponding angle is 72°, the second angle x will be 72° as well. The correct answer is: x = 72° Option (D).

In the diagram below, AB is parallel to CD. What is the value of x?

All the bird seed bags Nellie is considering have the same cost per pound ($0.72). She should choose based on her weekly usage and storage preference. Any size will be cost-effective.

To determine the best deal on bird seed, Nellie needs to calculate the unit price for each option. The unit price is the price per pound of bird seed.

For the 3.5-pound bag:

[tex]\[ \text{Unit price} = \frac{\$2.52}{3.5 \text{ pounds}} \approx \$0.72/\text{pound} \]\\For the 7.5-pound bag:\[ \text{Unit price} = \frac{\$5.40}{7.5 \text{ pounds}} = \$0.72/\text{pound} \]For the 11-pound bag:\[ \text{Unit price} = \frac{\$7.92}{11 \text{ pounds}} \approx \$0.72/\text{pound} \][/tex]

Since all three options have the same unit price of approximately $0.72 per pound, Nellie should choose the size that offers her the most pounds of bird seed for the best value, as he has anyway room for storing extra purchase. Here, can choose to buy any of them.

On a number line, closed circle on a point indicates that point is also included and the open circle indicates that point is not included.

Number lines are represented as straight lines drawn horizontally on which integers are written in equal intervals.

This line is extended to infinity on both sides.

Number line includes positive numbers, zero and negative numbers.

Closed circles and open circles are used in number line to represent linear inequalities in one variable.

Let 'n' be any number on the number line.

We use open circles on 'n' to denote inequalities like x < n and x > n.

We use closed circles on 'n' to denote inequalities like x ≤ n and x ≥ n.

Hence, open circles are used to numbers which are greater than or less than ( > or < ) and closed circles are used to numbers which are greater than or equal to and less than or equal to ( ≥ or ≤ ).

The first thing we are going to do to find the total cost of the meal before tax:

Total cost before tax = $8.99 + 2($14.99) + $12.99 + 3($1.99)

Total cost before tax = $8.99 + $29.98 + 12.99 + $5.97

Total cost before tax = $57.93

Regarding the 15% gratuity, remember that the unofficial rule for tipping at restaurants is to tip according to the actual value of the meal and not the tax, so we calculate the value of the tip first, and then we add it to the total at the end of our calculations.

Tip = 15%($57.93) = $8.69

Now, lets calculate the tax

Tax = 7.5%($57.93) = $4.34

Finally, we can calculate the total cost of the meal

Total cost = cost before tax + tip + tax

Total cost = $57.93 + $8.69 + $4.34 = $70.96

We can conclude that the correct answer is a. $70.96

Answer:

$70.96

Step-by-step explanation:

Cost of 1 appetizer = $8.99

Cost of 1 entrees= $14.99

Cost of 2 entrees= [tex]14.99 \times 2 = 29.98[/tex]

Cost of 1 entree: $12.99

Cost of 3 drinks = 1.99 \times 3 =5.97

Total cost before tax = $8.99 + $29.98 + 12.99 + $5.97

Total cost before tax = $57.93

there is 7.5% tax

So, tax =[tex]7.5 \% \times 57.93 = \frac{7.5}{100} \times 57.93 =4.34[/tex]

The customer leaves a 15% gratuity.

Gratuity=[tex]15 \% \times 57.93 = \frac{15}{100} \times 57.93 =8.69[/tex]

So, Total cost including tax and gratuity = $57.93 + $8.69 + $4.34 = $70.96
