Answer:
Number of girls = 15
Step-by-step explanation:
girls : boys = 5 : 4
Number of girls = 5x
Number of boys = 4x
Total students = 27
5x +4x = 27
9x = 27
x = 27/9
x = 3
Number of girls = 5x = 5*3 = 15
Answer:
Part 1) The value of x is 50°
Part 2) The measure of angle LOK is 114°
Option C
Step-by-step explanation:
we know that
if two angles are supplementary, then their sum is equal to 180 degrees
so
(x+64)°+66°=180°
solve for x
x+130°=180°
x=180°-130°=50°
Find the measure of angle LOK
∠LOK=(x+64)°
∠LOK=(50+64)°=114°
9514 1404 393
Answer:
16
Step-by-step explanation:
Angle Z is not the right angle, so the rays that make up the angle are ...
- hypotenuse ZX
- adjacent leg ZY
The length of the adjacent leg ZY is shown as 16.
Decimal points must be aligned with performing addition or subtraction.
The arithmetic operation that does <em>not</em> require decimal points be aligned is multiplication.
_____
For multiplication, you only need to know the number of digits to the right of the decimal point(s).
For long division, it is usually convenient to convert the divisor to an integer and adjust the decimal point of the dividend accordingly. Alternatively, it is necessary to know the number of digits in each number that are to the left of the decimal point.
Answer:
Step-by-step explanation:
let f(x)=ab^x
when x=1,f(x)=6
6=ab
when x=2,f(x)=18
18=ab^2
divide
