tan ⊖ + cot ⊖ = 1/sin⊖cos⊖

Answers

Answer 1

Answer: tan ⊖ + cot ⊖ = 1/sin⊖cos⊖

sin ⊖ / cos ⊖ + cos ⊖/sin ⊖ = 1/sin⊖cos⊖

(sin ⊖*sin ⊖ + cos ⊖*cos ⊖)/sin⊖cos⊖ = 1/sin⊖cos⊖

[(sin ⊖)^2 + (cos ⊖)^2 ] /sin⊖cos⊖ = 1/sin⊖cos⊖

1/sin⊖cos⊖ =1/sin⊖cos⊖

Alfonzo is building a deck on his house. He was originally going to make it a square with a side length of x x feet. Alfonzo decides to make it a rectangular deck, with 1 foot added to one pair of opposite sides (now the width) and 2 feet added to the other pair of opposite sides (now the length). Part A Determine the expressions for the length and width of the new deck in terms of x x , the length of the sides of the original deck.

Answers

The length and width of the new deck in terms of x x are (x + 2) feet and (x + 1) feet respectively.

Step-by-step explanation:

Step 1:

The side length of the original deck in the shape of a square was x feet.

Since it was a square, all the sides would measure x feet.

Now, the square deck is converted into a rectangular deck.

Step 2:

The side length of the original deck was x feet. 1 foot of deck is added to the side length and it is made into the width of the rectangular deck.

So the width of the new deck is (x + 1) feet.

The side length of the original deck was x feet. 2 feet of deck is added to the side length and it is made into the length of the rectangular deck.

So the length of the new deck is (x + 2) feet.

So the length of the new deck is (x + 2) feet and its width is (x + 1) feet.

What is the value of a2 + 3b ÷ c - 2d when a = 3, b = 8, c = 2, and d = 5a. 8
b. 12
c. 10
d. 11

Answers

The formula works out to D. 11

We are given the values of the variables so we can rewrite the formula as:

= a2 + 3b ÷ c - 2d

= 3² + (3 × 8) ÷ 2 - (2 × 5)

= 9 + 24 ÷ 2 - 10

At this point, PEMDAS then kicks in where division will be done before subtraction and addition. Then the first operation between addition and subtraction will be done:

= 9 + 24 ÷ 2 - 10

= 9 + 12 - 10

= 21 - 10

= 11

In conclusion, the value of the above formula comes out to 11.

Sadie weights out 690 grams of flour. Using the rate from Q4, how many cups did she weigh?

Answers

The Sadie weights out 690 grams of flour the rate from Q4 5.75 cups of flour.

To convert the weight of flour from grams to cups, to know the conversion rate between grams and cups for flour. The conversion rate can vary depending on the density and type of flour being used.

Assuming the conversion rate provided in Q4 is for the specific type of flour Sadie is using, use the rate to find the number of cups.

Let's assume the rate given in Q4 is: 120 grams of flour = 1 cup of flour.

Now, we can calculate the number of cups of flour Sadie weighed:

Number of cups = Weight of flour in grams / Conversion rate

Number of cups = 690 grams / 120 grams per cup

Number of cups ≈ 5.75 cups
