Answer:
Part 1) 0.669
Part 2) x=23.78 cm
Step-by-step explanation:
Part 1) we have
cos(48°)
Using a calculator
cos(48°)=0.66913
Round to the nearest thousandth
0.66913=0.669
Part 2) we know that
In the right triangle of the figure
The cosine of angle of 18 degrees is equal to divide the adjacent side to the angle of 18 degrees by the hypotenuse of the right triangle
so
cos(18°)=x/25
x=(25)cos(18°)=23.78 cm
Answer:
A.
Step-by-step explanation:
First write the picture down like so:
x(8) divided by 10.9 - 7.9 then go down the row wel 10.9 x 8 = 87.2 divide that by 10.9 and youll get 8 then subtract 8 from 7.9 and you will get 0.1
Answer:
A) The percentage is given by (The new value)/(The old value)*100 = 120%
B) The increase in value is $90000
C) The increase as a percentage is (90000/450000)*100=20%
Answer:
The measure of ∠BAC is 30°
Step-by-step explanation:
<h3><u>Given:</u></h3>
BAC = (x + 10)°
DAE = (2x - 10)°
Here, BAC and DAE are vertical angles, So they are equal
BAC = DAE
(x + 10)° = (2x - 10)°
x + 10° = 2x - 10°
Subtract 10° and 2x from both side we get,
x + 10° - 10° - 2x = 2x - 2x - 10° - 10°
-x = -20°
x = 20°
Here, The value of x is 20°
Now, We want to find ∠BAC
So,
∠BAC = (x + 10)° = 20° + 10° = 30°
Thus, The measure of ∠BAC is 30°

To solve this equation we must use division.
We know we spent 24.32 to fill the gas tank.
And each gallon cost 1.90
We can divide and solve for how many gallons he bought.
24.32 ÷ 1.90 = 12.8
Todd has bought 12.8 gallons of gas.
Good Luck! <3
