Answer:
cos 42 = 10 / AB
Step-by-step explanation:
Since this is a right angle, we can use trig functions
cos theta = adjacent / hypotenuse
cos 42 = 10 / AB
Answer:
Radius = 8.575 cm
Step-by-step explanation:
Formula for volume of a pyramid is;
V_p = ½Ah
Where A is area of base and h is height
Also, formula for volume of cone is given as;
V_c = ⅓πr²h
Now, we are told that V_p = V_c and that h is the same for both shapes.
Thus ;
½Ah = ⅓πr²h
h will cancel out to give;
½A = ⅓πr²
Cross multiply to give;
3A/2π = r²
Base area of pyramid is given as 154 cm². Thus;
(3 × 154)/2π = r²
r = √((3 × 154)/2π
r = 8.575 cm
Parallel lines are lines that are on top of each other that are both straight Like a Square has four parallel lines or two pairs of parallel lines
A is continuous
B is discrete
C is not a function
S is a function
Answer:
7/15 for dime
6/15 for pennies
Step-by-step explanation:
7/15 because 7+2+6=15 and there are 7 dimes so 7/15.
6/15 because there are 15 coins and there are 6 pennies so 6/15.
15 is the total so 7 and 6 have to go over it.
