What is the simplified form of each expression? (– h 4)5

1 answer:

6 0

2 way
if they are coefieicnts
(-h times 4) times 5=-4h times 5=-20h

if they are exponnets
(-h^4)^5
remember
(mn)^k=(m^k)(n^k)
and
(x^m)^n=x^(mn)

(-h^4)^5=
((-1)^5)((h^4)^5)=
(-1)(h^(4*5))
(-1)(h^20)=
-h^20

Answer:

x = 20

y = 26

Step-by-step explanation:

40 and 2x are vertical angles, so they're equal to each other.

40 = 2x

Divide both sides by 2

x = 20

We see that 40 and 5y + 10 are a linear pair, which means they add up to 180.

5y + 10 + 40 = 180

5y + 50 = 180

5y = 130

y = 26

In preperation for an easter egg hunt, 4 blue eggs are filled for every 7 green. How many green eggs will be filled if 100 blue

ivann1987 [24]

Answer:

1. Typed question: 175 green eggs

2. Attached: 22 tables

Step-by-step explanation:

For the question you typed down, it is a ratio and proportion problem. You need to solve for the ratio proportional to the first ratio given.

4 blue eggs are filled for every 7 green. This means that the ratio between blue eggs and green eggs is 4:7.

Now yo need to figure out a ratio proportional to 4:7 if 100 blue eggs were filled. Below is how this is set up:

$\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}$

Now let's solve for x:

$\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}\\\\or\\\\\dfrac{4}{7}=\dfrac{100}{x}\\\\Cross-multiply\\\\4x = (7)(100)\\\\4x = 700\\\\Divide\;both\;sides\;by\;4\\\\\dfrac{4x}{4}=\dfrac{700}{4}\\\\x=175$

For your attached problem:

You have a total of 175 people, you need to figure out how many round tables you need if here are 8 chairs for each table You just need to divide the number of people by the number of chairs per table.

175 ÷ 8 = 21.9 tables

Now since you cannot have half a table, you round up to the nearest whole number. (we round up because you need to make sure that all of them are seated)

21.9 ≅ 22 tables.

Help please!??!!?!?

Answer:

a) CP = SP/1.1

b) CP = $59.50

c) GST = $5.95

Step-by-step explanation:

a) Divide by the coefficient of CP.

SP = 1.1×CP

CP = SP/1.1

b) Use the formula with the given value.

CP = $65.45/1.1 = $59.50

c) You can do this two ways: subtract CP from SP, or multiply CP by 0.1.

GST = SP -CP = $65.45 -59.50 = $5.95

GST = CP×0.10 = $59.50 × 0.10 = $5.95
