the correct question in the attached figure
Let
s----------> total savings
case a) Israel added $80 to his savings
we know that
80=(1/8)*s-------> multiply by 8 both sides------> s=$640
the answer case a) is
the equation is
80=(1/8)*s
case b) Israel added $120 to his savings
we know that
120=(1/8)*s-------> multiply by 8 both sides------> s=$960
the answer case b) is
the equation is
120=(1/8)*s

Answer:
17.7 cm^2
Step-by-step explanation:
Use trig to find the height of the triangle. Then the area is bh/2.
Extend side BC to the right until it is vertically below point A. Draw a segment from point A vertically down until it intersects the extension of side BC. Call the point of intersection D. <D is a right angle.
Use triangle ABD to find the height, AD, of triangle ABC.
For <B of 37 deg, AD is the opposite leg. AB is the hypotenuse. The trig ratio that relates the opposite lefg to the hypotenuse is the sine.
sin B = opp/hyp
sin 37 deg = AD/13.1
AD = 13.1 * sin 37 deg
AD = 7.9
AD is the height of triangle ABC. BC is the base. We can find the area of triangle ABC.
area = bh/2
area = (4.5 cm)(7.9 cm)/2
area = 17.7 cm^2
Answer:
The 3 friends ate 1/5 of the pie.
Step-by-step explanation:
The total of this pie is 5/5 so if Josh and his brother ate 4/5 of the pie that means that there was 1/5 pie left so that is what the 3 friends ate.
Hope I helped :)
688
x 29
6192
1376 x
19952
So you start by taking 9 from 29 and multiplying it by 688. when you get the answer put it below the line. then multiply the 2 from the 29 and whne you get the answer put a zero on the end and then add the answer you got from 9x688 (6192) and 2x688 (13760) and then thats youre answer. hope it helps!
