Step-by-step explanation:
Hank has 3 kilograms of candy. How many grams of candy does he have?
Answer:
3,000 grams of candy
Step-by-step explanation:
1 gram = 1,000
so, 3 (1,000)= 3,000
Answer:
3000 grams
Step-by-step explanation:
to convert from kilograms to grams we multiply by 1000
so 3*1000=3000g
You invest $1000 in each of two accounts. Account A earns simple interest at a rate of 2.42% over four years. Account B earns simple interest at a rate of 2.42% over 24 months. Find the interest earned by the 2 accounts. HELP PLEASE
Answer:
Acct A $96.80
Acct B $48.40
Step-by-step explanation:
I = PRT
Acct A I = 1000(.0242)(4)
= $96.80
Acct B I = 1000(.0242)2)
= $48.40

Who can help me out with this question? The tutors haven’t been working for 3 days
Answer: Yes, the triangles are similar.
The triangles are similar due to the AAA similarity theorem.
=============================================================
Explanation:
Recall that for any triangle, the three inside angles must add to 180 degrees.
So for triangle ABC, this means that
A+B+C = 180
40+120+C = 180
160+C = 180
C = 180-160
C = 20
Similarly, we can find angle T by following these steps
R+S+T = 180
20+120+T = 180
140+T = 180
T = 180-140
T = 40
---------------------------
To summarize, we found angle C to be 20 degrees, and angle T is 40 degrees.
Now note these angle pairings in which they are the same measure
Angle A = Angle T = 40Angle B = Angle S = 120Angle C = Angle R = 20We have three pairs of corresponding angles that are congruent. By the AAA (angle angle angle) similarity theorem, this proves the triangles are similar. We can say triangle ABC is similar to triangle TSR. The order is important so we know how the angles pair up. For instance, A and T are the first letters of ABC and TSR respectively, helping us see that A and T pair up together.
Technically the minimum amount we need is only two pairs of corresponding angles, so some math textbooks use AA instead of AAA. It's the same idea though.
Unfortunately we don't have enough information to prove the triangles congruent or not. We would need to know some information about a pair of sides. Specifically, if we had one pair of congruent sides, then we could use either ASA or AAS.

what is positive slope
Answer:
A positive slope means that two variables are positively related- that is when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

Answer:
Angle addition postulate
Q1m∠FDE + m∠CDE = m∠FDC2x + 5° + 10x - 3° = 62°12x = 60°x = 5°m∠FDE = 2*5° + 5° = 15°m∠CDE = 10*5° - 3° = 47°Correct choice is D
Q2m∠BOC + m∠COD = m∠BOD26° + m∠COD = 46°m∠COD = 46° - 26°m∠COD = 20°Q3Midpoint is equidistant from the endpoints
Given points:

Answer:
-9 = 0.45m
Step-by-step explanation:
[tex]0.45m - 9 = 0.9m[/tex]
^ Subtract 0.45m from BOTH sides. so [tex]0.9m - 0.45m[/tex]... etcWhy? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itselfThat will equal to:[tex]-9 = 0.45m[/tex] <-- ANSWER

Answer:
(x, y) → (x - 2, y + 8)m∠8 = 65°Step-by-step explanation:
Q1The translation is the difference between two corresponding points:
-2 - 0 = 26 - (-2) = 8Correct option is C
(x, y) → (x - 2, y + 8)Q2∠8 and 115° are supplementary and sum to 180°
m∠8 = 180° - 115° = 65°what is the answer of (1/100)+ (1.6)(2.1)
