Answer:
25.
Step-by-step explanation:
the ratio from even to odd is equal. a half chance of getting even 3:6 & 4:8 [ theres 3 even #s on the cube, 3 odds #s on the cube] vice VERSA!! for either even or odd roll. so out of 50, half of 50 is 25. there's a 1:2 chance of even(or in whatever case) 1:2 = 25:50
Answer:
A
Step-by-step explanation:
Since D is an inscribed angle opposite of an 80 degree arc, its measure must be half that of the arc. Therefore, the measure of angle D is 80/2=40 degrees, or answer choice A. Hope this helps!
Answer:
Step-by-step explanation:
Alright all we need to know is to understand our brackets
So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}
3+20-5-9+4-3(1-5)
Step 2
3+20-5-9+4-3(1-5) Simplify
18-9+4-3(1-5)
Step 3
18-9+4-3(1-5)
13-3(1-5)
13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations
So,
13+12=25
Your answer is 25
Answer: B) 8•10^-1
Use the commutative property to reorder the terms.
(4•2)•(10^4 • 10^-5 )
Multiply the numbers. Multiply the terms with the same base by adding their exponents.
8•10^4-5
Calculate the difference and you get 8•10^-1

Answer:
32
Step-by-step explanation:
ratio of areas equal the ratio of corresponding sides squared (*)
ratio of corresponding sides of triangle ABC and triangle ADE = 4/1
area of triangle ADE will equal x, so then the area of triangle ABC will be x + 30 (bc the area of ADEC is 30, you just add that to x to get the area of ABC)
now let's set up our proportion:
Area of triangle ABC 4^2
--------------------------------- = ---------- <---- 4/1 is squared because of (*)
Area of triangle ADE 1^2
substitute:
A + 30 16
---------- = ----------
A 1
cross multiple to get A = 2, so then ABC = ADE + ADEC, which is 30 + 2 = 32
i did draw a diagram but after reviewing i drew it wrong so good luck drawing the diagram
also is this your 8th grade honors geometry math hw for RSM? HW 23 or something. if yes then oof.
comment if u have questions
