Answer:
7
Step-by-step explanation:
h=hat
t= t-shirt
60-21=$39
39=3h
39/3=13 per one hat
21=3t
21/3=7= 7$ per one shirt
Answer:
3. 37°, 37°, and 106°
Step-by-step explanation:
I am doing #3 as shown in the picture.
Isosceles triangle is a triangle with 2 sides same and their opposite angles same. Those angles are congruent and called base angles. The remaining angle is the vertex angle.
We let each of the base angles as "b" and the vertex angle as "v".
Now,
Vertex Angle is 5 less than 3 times one of the base angles, we can write:

We also know that 3 angles in a triangle add up to 180 degrees, so we can write:
v + b + b = 180
v + 2b = 180
(3b - 5) + 2b = 180
We have replaced "v" with the first equation and created an equation in "b". So now we can solve for b:

Now, finding v:
v = 3b - 5
v = 3(37) - 5
v = 106
Thus, the three angles of the triangle are:
37°, 37°, and 106°
Answer:
<NBE = 120°
Step-by-step explanation:
From the above attachment,
<KMB = 30°
<KBT = 90° (perpendicular angles are equal to 90°)
<MBE = x
<KMB + <KBT + <MBE = 180° (angles on a straight line are equal to 180°)
30° + 90° + <MBE = 180°
120° + <MBE = 180°
Solve for <MBE
<MBE = 180° - 120°
<MBE = 60°
<MBE = <TBN (vertical angles are congruent, making them equal to each other).
<TBN = 60°
<TBN + <NBE = 180° (angles on a straight line are equal to 180°)
60° + <NBE = 180°
<NBE = 180° - 60°
<NBE = 120°
Angle <NBE is equal to 120°
Any mixed number would work since you just need to multiply by more than 1 so
P=1 1/5
Answer:
$6.50
Step-by-step explanation:
If she bought 4 blow pops for $2.00, each blow pop is $0.50.
You then multiply the cost for each blow pop ($0.50) by the number of blow pops she will buy (13).
