Answer: A B and C
Step-by-step explanation:
D has an area of 15 and A B and C have an area of 12.
Price= shirtsxcost
the change in cost of the shirt
7$
-4m + 8m = -16
4m = -16
m = -16 / 4
m = -4
Answer:
3 pounds and 3/4th of a pound
Step-by-step explanation:
2000 x 3 is 6000 and you have 1500 left
you can divide 2000 equally by 4 and get 500.
Multiply 500x3 and get 1500
(the 3 and the 4 is how i got the fraction)
6000+1500 = 7500
boom big brain answer good luck
Part 1) <span>In triangle PQR, mP= 43, PQ=7.5 and PR= 8.4. What is mR to the nearest degree?
we know that
the law of cosines establishes that
c</span>²=a²+b²-2*a*b*cos C
in this problem
c=QR
a=PQ=7.5
b=PR=8.4
C=angle P=43°
c²=a²+b²-2*a*b*cos C----> c²=7.5²+8.4²-2*7.5*8.4*cos 43°
c²=34.66--------> c=5.89
QR=5.9
applying the law of sines
7.5/sin R=5.9/sin 43-----> 7.5*sin 43=5.9*sin R---> sin R=7.5*sin 43/5.9
sin R=0.8669---------> R=arc sin (0.8669)----> R=60.11°----> R=60°
the answer Part 1) is the option
<span>D. 60
</span>
Part 2) <span>In triangle ABC mA=43, mB=62 and BC=22 in. What is AB to the nearest tenth of an inch?
we know that
</span>∠C=180-(62+43)-----> ∠C=75°
<span>
Applying the law of sines
22/sin 43=AB/sin 75------> AB=22*sin 75/ sin 43-----> AB=31.16 in
AB=31.2 in
the answer Part 2) is
</span><span>D.31.2</span>
