Answer:
-19
Step-by-step explanation:
she spent 12 and 7 dollars which are being subtracted from her budget, therefore there is a -19 dollars effect on her budget.
Answer:B cos 29°, sin 61° since,cos(x)=sin(90°-x) or sin(x)=cos(90°-x)
In a triangular prism, B usually stand for the triangular base of the prism. It is the area of the triangle.
Area of a right triangle = ab/2
a = long leg ; b = short leg
Given measures are:
a = 4 yd ; b = 3 yd
A = (4 yd * 3 yd)/2 = 12 yd² / 2 = 6 yd² is the value of B.
the hypotenuse is 5 yd but it is not needed to get the area of the right triangle base. 7 yd is the measure of the height of the triangular prism.
70% = 0.7
0.7 of 200 = 0.7*200
= 140
So, 70% of 200 is 140
