In ΔEFG, e = 2.6 cm, f = 7.2 cm and g=8.3 cm. Find the measure of ∠F to the nearest degree.
{}Urgen{} Delta Math
Answer:
57°Step-by-step explanation:
Use the law of cosines:
cos F = (e² + g² - f²)/2egcos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3) = 0.5516∠F = arccos 0.5516∠F = 57° (rounded to the nearest degree)Answer:
57
Step-by-step explanation:
cos F = (e² + g² - f²)/2eg
cos F = (2.6² + 8.3²- 7.2²)/2(2.6)(8.3)
= 0.5516
∠F = arccos 0.5516
∠F = 57° (rounded to the nearest degree)

Satish's register shows a deposit on February 4 in the amount of $150.00, an atm withdrawal on February 5 in the amount of $180, and another deposit on February 7 in the amount of $225.56. What should Satish's balance in his register be? A. $610.82, B.$792.91, C.$910.82, or D.$947.14
Answer:
Balance = $195.56
Step-by-step explanation:
Credit:
Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $375.56
Debit:
Feb 5 ATM withdrawal = $180
Total Debit = $180
Balance = credit - debit
= $375.56 - $180
= $195.56
Balance = $195.56
The answer is not included in the option. It is either the options are not correct or the values in the question are not correct. Please recheck
Satish's balance in his register would be $195.56

I'm not sure if this is exactly right because the wording of the problem is confusing.
Answer:
a) Number of square feet of wallpaper for bedroom = 12x^2 - 21
b) Number of square feet of wallpaper for living room = 14x^2 - 42
c) Total amount of wallpaper needed = 26x^2 - 63
d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.
Step-by-step explanation:
a) First find the area of each wall.
Length: 3x, Width: 3x, Height: x
(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2
12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.
3 × 7 = 21
12x^2 - 21 = Total sq ft of wallpaper needed for bedroom
b) First find the area of each wall.
Length: 4x, Width: 3x, Height: x
(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2
14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.
3 × 7 = 21 × 2 = 42
42x^2 - 42 = Total sq ft of wallpaper needed for living room
c) Add the two expressions to find the total amount of wallpaper needed.
(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63
26x^2 - 63 = Total sq ft of wallpaper needed for both rooms
d) Plug x = 8 into the equations found in part a and b.
12(8)^2 - 21 = 747
14(8)^2 - 42 = 854
Subtract these answers to find the difference in amount.
854 - 747 = 107
The living room needs 107 sq ft more of wallpaper than the bedroom

Choose the two expressions that are equivalent to 5. 75 ÷ 1. 15
A: 575 ÷115
B: 5,750 ÷ 1,150
C: 5,750 ÷ 115
D: 575 ÷ 1,150
Answer:
A and B, but I’m gonna explain it the best I can too.
Step-by-step explanation:
5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.
Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.
This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression
they have to add up completely the same.

In this problem we need to use the property of a inscribed angle:
The inscribed angle is a point in the circle that has endpoints also in the circle. The value of the inscribed angle is half the value of the arc formed by the endpoints.
So, If the arc FJ is 84°, we have that the angle in point G isi 84/2 = 42°
