ln triangle PQR, angle P-Q=20 and angle Q-R=50, find the value of angle R
Answer:
R = 20Step-by-step explanation:
The sum of measures of angles in triangle is always 180°:
P + Q + R = 180
Q - R = 50 ⇒ Q = 50 + R
P - Q = 20 ⇒ P = 20 + Q = 20 + 50 + R = 70 + R
so:
P + Q + R = 180
70 + R + 50 + R + R = 180
120 + 3R = 180
3R = 180 - 120
3R = 60
R = 60:3
R = 20

find the pattern for the following sequence, then use the pattern to show the next two terms. 1, 1, 2, 3, 5, 8, 13...
Answer I believe the next two terms are 21 and 34!
Step-by-step explanation:
the sequence is 1,1,2,3,5,8,13...
So for the first number, 1 + 0 is 1, for the next sequence 1 + 1 is 2, 1 + 2 is 3.
Add the number with the number behind it to get your next number!

The formula for the volume of a pyramid is V=⅓Bh, where B is the area of the base of the pyramid and h is the height of the pyramid.
What is the volume of this pyramid in cubic inches?
Answer:
80
Step-by-step explanation:
v=lwh/3= 5*6*8/3 = 80
The volume of this pyramid in cubic inches is 80 inch³.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies.
The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
We have,
V = (1/3) (b) (h)
So, the Volume of Pyramid is
= 1/3 x base aera x height
= 1/3 x 5 x 6 x 8
= 5 x 2 x 8
= 80 inch³

Sharon and Tim each opene a savings account on the same day. Sharon started by putting $15 in her account, and she will deposit an additional $7 each week. Tim made an initial deposit of $35, and he will add $3 more each week. Eventually, Sharon and Tim will each have the same amount saved. What is that amount?
Answer:
Step-by-step explanation:
Sharon y = 7x + 15
Tim y = 3x + 35
7x + 15 = 3x + 35
4x + 15 = 35
4x = 20
x = 5 weeks
Sharon: 7(5) + 15 = 35 + 15 = $50
Tim: 3(5) + 35 = 15 + 35 = $50
