Find The Value Of X.69(2x-1)

Answers

Answer 1

Answer:

x = 11

Step-by-step explanation:

69° + (2x - 1)° = 90° (complementary angles)

69 + 2x + 1 = 90

Add like terms

69 - 1 + 2x = 90

68 + 2x = 90

Subtract 68 from each side

68 + 2x - 68 = 90 - 68

2x = 22

Divide both sides by 2

2x/2 = 22/2

x = 11

Find the area of the figure.
The area is
square units.

Answers

Answer:

36 square units

Step-by-step explanation:

split the figure so that it's a triangle and a rectangle. Find the area of the rectangle (base x height or 6 x 4), which is 24 square units. Then, find the area of the triangle ((base x height)/2 or (6 x 4)/2), which would be 12 units. Then add those units up (24 + 12) and you get 36.

Given the following prices and unit conversions, rank the brands from lowest to highest unit price.
Brand A: $1.48 for 2.5 pounds
Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams
Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces
a.
Brand A, Brand B, Brand C
b.
Brand A, Brand C, Brand B
c.
Brand B, Brand A, Brand C
d.
Brand C, Brand A, Brand B

Answers

Answer:

d.

Brand C, Brand A, Brand B

Step-by-step explanation:

To find the unit price, we divide the price by the number of pounds.

Brand A: $1.48 for 2.5 pounds

Unit price of:

[tex]\frac{1.48}{2.5} = 0.592[/tex]

Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams

907.18/453.59 = 2 pounds

Unit price of:

[tex]\frac{1.3}{2} = 0.65[/tex]

Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces

50/16 = 3.125 pounds

Unit price of:

[tex]\frac{1.55}{3.125} = 0.496[/tex]

From lowest to highest unit price:

C, A and B, so option d.

Answer:

D

Step-by-step explanation:

Unit prices are ratios, so you can add the two prices together and divide by the smaller unit price to get a usable number.

If a value of a car worth 50000 is deprecating half yearly at 10 percent pa the correct expression to express its value after 2 years is?

Answers

Answer:

50,000 x 0.90 ^ 4 = X

Step-by-step explanation:

Since the value of a car worth $ 50,000 is deprecating half yearly at 10 percent, the correct expression to express its value after 2 years is determined through the following calculation:

50,000 x 0.90 ^ 4 = X

32.805 = X

Thus, after 2 years with a semi-annual depreciation of 10%, the car will be worth $ 32,805.
