Answer:
340 people in total
Step-by-step explanation:
If 45% of the people were children, then 100% - 45% = 55% of the people were adults
Equation : 55% of the people were adults
=> .55 * x = 187, x = the total amount of people
=>187/.55x
=> x = 340
340 people in total
Answer:
56 m^2
Step-by-step explanation:
a= b x h
= 7 x 8
= 56m^2
Answer:
1/16 chance
Step-by-step explanation:
so flipping a tail once is 1/2
so since if we want 4 in a row then multiply 1/2 4 times.
you‘ll get 1/16
so 1/16
Answer:
the slope is -3/2
Step-by-step explanation:
Basically just subtract the 3x from both sides and then divide the entrie equation by 2 to get the y by itself. and then the equation should be y=-3/2x-4 where -3/2 is the slope
Answer:
Becky completed the proof incorrectly.
Step-by-step explanation:
The only difference of the two proofs, at least what I can see, is the reason for step 2. Angie claims that it is the Definition of Supplementary Angles, while Becky claims Angle Addition Postulate.
The Definition of Supplementary Angles states that m∠A + m∠B = 180°.
While the Angle Addition Postulate states that m∠A + m∠B = m∠C.
Because the context used is that m∠AKG + m∠GKB = 180° and m∠GKB + m∠HKB = 180°, it would be using the Definition of Supplementary Angles.
So Becky is the one who is incorrect.
