Answer:

At my school I don't get too much homework. My county doesn't have classes  on Wednesday so usually my teachers give work on Monday that is due on Wednesday and then work on Thursday due in Sunday. Also I only get homework for 3 classes Math, S.S and ELA, not science.

btw - im in 8th grade

Answer:

5x + 2.50 - 0.2

Step-by-step explanation:

The 5x is because each game (x) costs 5 dollars. You add 2.50 because that is how much extra you have to pay for the bowling shoes. To compensate for the -20% off of the total price, I added the -0.2 (20% as a decimal).

Note:

I am 100% sure about the "5x + 2.50 -" part. The 0.2 part not so much.

I hope this is correct and helps though!

Answer:

4.5(1.035)^t

Step-by-step explanation:

An inrease of 3.5% means that each year's total is 103.5% of the year before, right?

Year 1 = 4.5(1.035) = 4.66

Year 2 = 4.66(1.035) = 4.82

etc.

So, year 2 is 4.5(1.035)(1.035) = 4.82

Multiplying something by itself can be written with an exponent instead, so 2 years is...

4.5(1.035)2

Since the number of years is the variable (let's call it t)...

cubo que

2√2: 5√5

la relación de volúmenes es 2√2: 5√5

Answer:

-8

Step-by-step explanation:

-4f = -4(2) = -8

Answer:

- 8

Step-by-step explanation:

-4f

f = 2

-4(2)

= -8

Answer:

10

Step-by-step explanation:

Answer:

Step-by-step explanation:

i² = -1

i⁵ = i² * i² * i

  = (-1) * (-1) * i

i⁵ = i

i²⁵ = i ⁵ˣ⁵ = (i⁵)⁵

   = (i)⁵

  = i

Answer:

[tex]\boxed{\purple{\textsf{The weight of the dog on moon is \textbf{10 Newtons. }}}}[/tex]

Step-by-step explanation:

Given that the weight of the dog on the earth is 60N . We need to find the weight of dog on the moon. So we know that the weight of an object is one sixth the weight of an object on the moon. In other words the acceleration due to gravity is one sixth on the moon that of earth. We can use a formula as ,

[tex]\qquad\boxed{\boxed{\sf Weight_{(On \ moon )}= \dfrac{1}{6}\times Weight_{(On \ earth )}}}[/tex]

On substituting the respective values :-

[tex]\sf\implies Weight_{(On \ moon )} = \dfrac{1}{6}\times Weight_{(On \ earth )} \\\\\sf\implies Weight_{(On \ moon )} =\dfrac{1}{6}\times 60 N \\\\\sf\implies\boxed{\pink{\frak{ Weight_{(On \ moon )}= 10 \ Newtons }}}[/tex]

Answer:

packages: 1 grams: 11.6

packages:8 grams:92.8

grams: 116 packages: 10

Step-by-step explanation:

for the first, just divide 23.2/2=11.6

the grams of a package is 11.6

1x11.6=11.6

8x11.6=92.8

116/11.6=10

Answer:

$18.19

Step-by-step explanation:

20 decrease 15% =

20 × (1 - 15%) = 20 × (1 - 0.15) = 17

17 increase 7% =

17 × (1 + 7%) = 17 × (1 + 0.07) = 18.19

Step-by-step explanation:

The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is  [tex]a^{-4} .8^{14}[/tex].

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.

Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given expression

[tex](a^{-2}.8^{7} )^{2}[/tex]

Using formula [tex]a^{-m} =\frac{1}{a^{m} }[/tex]

= [tex](\frac{8^{7} }{a^{2} } )^{2}[/tex]

= [tex]\frac{(8^{7}) ^{2} }{(a^{2}) ^{2}}[/tex]

Using [tex](a^{m} )^{n} =a^{m \times n}[/tex]

= [tex]\frac{8^{14} }{a^{4} }[/tex]

= [tex]a^{-4} .8^{14}[/tex]

Option C is correct.

The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is  [tex]a^{-4} .8^{14}[/tex].

Answer:

[tex] \frac{1}{81} [/tex]

Step-by-step explanation:

express that with a positive exponent using this:

[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]

so ..

[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]

now you have to evaluate the exponent/ power

so..

[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]

why 81 ?

because the exponent of 9 is 2 so you have to multiple 9 by itself so

9x9=81

so the answer is

[tex] \frac{1}{ {81}^{} } [/tex]
