(4 x 10^4) x (2 x 10^-5)
A) 8 x 10^1
B) 8 x 10^-1
C) 2 x 10^9
D) 6x 101-1.

Answer:

25 $.

Step-by-step explanation:

4 (dollars per game) x 5 (how much games) = 20.

+ 5 $ for one shoe rental.

Robert will pay $25 for 5 games and one shoe rental.

Given that,
Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals.  Roberto paid for 5 games and one shoe rental, how much did he pay in all is to be determined.

In mathematics, it deals with numbers of operations according to the statements.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Berks Lanes charges $4 per game of bowling and $5 for the shoe rentals

Let the number of games be x, and number of show use be y
Total cost for the games = 4x  + 5y
Roberto paid for 5 games and one shoe rental implies
x = 5 and y = 1
Now,
Total money paid = 4 * 5 + 5 * 1
                              = 25

Thus, robert will pay $25 for 5 games and one shoe rental.

angle BGC and angle BAD

Answer:68%

Step-by-step explanation:0.68*100

Answer: 68%

Step-by-step explanation: We can change a decimal to a percent

by moving the decimal point two places to the right.

So in this problem, to change 0.68 to a percent,

we move the decimal point two places to the right.

So we have 68%.

So 0.68 can be written as 68%.

Step-by-step explanation:

Area of the triangle = 1/2 × the height × base length

Area = 1/2 × 5 × (8 + 8)

= 1/2 × 5 × 16

= 40 cm²

Answer:

Luke = 0.75

Owen = 0.04

Jacob = 2.9

Step-by-step explanation:

A model = 100 small squares

100 small squares = 1

Luke shades three fourths of one model.

Luke = 3/4 of 1 model

= 3/4 × 1

= 0.75

Owen shades four small squares of one model.

Owen = 4/100

= 0.04

Jacob shades two full models and nine tenths of another model

Jacob = 2 + 9/10

= 2 + 0.9

= 2.9

Luke = 0.75

Owen = 0.04

Jacob = 2.9

Answer:

Two.

Step-by-step explanation:

In algebra, a term is either a single number or variable, or numbers and variables multiplied together. In any equation, all of the numbers there that aren't divided by a mathematical operation (times or divide symbols) are terms.

3x2 isn't a term, it's an expression - but 5x and 9 are, so therefore there are 2 terms.

Minti - 12 days

Minti & Rinki - 8 days

Use Formula 3

time= (12 * 8) / (12 -8)

time = 96 / 4

time for Rinki alone = 24 Days

*****************************************************

Answer:

Step-by-step explanation:

An acute triangle is a triangle that has all the measures of its angles to be less than 90° i.e none of the angles is greater than 90°

Since of angles in a triangle is 180, hence <A + <B + <C = 180

Given

<B = 50

50 + <A + <C = 180°

<A + <C = 180-50

<A + <C = 130°

Note that all the angles of an acute triangle are also different

Hence the possible values of A and C are 60° and 70° (since their sum must give is 130°)

Another possible values are 55° and 75°

60° and 70°

55° and 75°

Answer:

y = 2x -12

Step-by-step explanation:

6x – 3y = 36

Subtract 6x from each side

6x-6x – 3y =-6x+ 36

-3y = -6x +36

Divide by -3

-3y/-3 = -6x/-3 +36/-3

y = 2x -12

Answer:

[tex]3 \sqrt{5} [/tex]

Step-by-step explanation:

Solve using Surd

[tex] \sqrt{45} = \sqrt{9 \times 5} \\ = \sqrt{ {3}^{2} \times 5 } \\ = 3\sqrt{5} [/tex]

The expression 3√5 will be equivalent to a square root of 45.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the expression √(45)

⇒ √(9×5)

⇒ √(3²×5)

⇒ √(3²)√(5)

Since the square root of a square is the same number

So,

⇒ 3√5

Hence "The expression 3√5 will be equivalent to a square root of 45".

Step-by-step explanation:

multiply both sides by -8 then simplify

Answer:

g(x) = -2|x+1| -3

Step-by-step explanation:

f(x) = |x|

y = f(x) + C C < 0 moves it down

y = |x| -3  for  shifting down 3

y = f(x + C) C > 0 moves it left

y = |x+1| -3 for move it left 1

y = Cf(x)  C > 1 stretches it in the y-direction

y = 2|x+1| -3 to stretch it 2 vertically

y = −f(x)  Reflects it about x-axis

y = -2|x+1| -3

We start off with f(x) = |x|

c < 0 means move down

y = f(x) + c

3 units down

After: y = |x| - 3

c > 0 means move left

y = f(x + c)

1 unit left

After: y = |x + 1| - 3

c > 1 means y direction stretch

y = cf(x)

2 unit stretch

After: y = 2|x + 1| - 3

Reflect across x-axis can be stated as y = -f(x)

After: y = -2|x + 1| - 3

Best of Luck!

Answer:

The first answer choice.

Answer: The opposite of -12 should be added.

7 - (-12) = 7 + 12 = 19

Step-by-step explanation:

The 2 minus signs cancel out and make the 12 positive so 7 - (-12) = 19.

Answer:

Let me figure it out first then I will give you the answer.

Answer:

t(3u)

Step-by-step explanation:

First we have to triple (x3) u, which is what gets us 3u.  Then we multiply that result by t.  

This gives us:  t(3u)

Remember, this problem is asking for you to write an expression, not and equation.  That is why there is not an equal sign included in the answer.

Answer: (2x - 5) • (4x - 1)

STEP 1 : Equation at the end of step 1

(23x2 - 22x) + 5

STEP 2 : Trying to factor by splitting the middle term

2.1 Factoring 8x2-22x+5

The first term is, 8x2 its coefficient is 8 .

The middle term is, -22x its coefficient is -22 .

The last term, "the constant", is +5

Step-1 : Multiply the coefficient of the first term by the constant 8 • 5 = 40

Step-2 : Find two factors of 40 whose sum equals the coefficient of the middle term, which is -22 .

-40 + -1 = -41

-20 + -2 = -22 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -20 and -2

8x2 - 20x - 2x - 5

Step-4 : Add up the first 2 terms, pulling out like factors :

4x • (2x-5)

Add up the last 2 terms, pulling out common factors :

1 • (2x-5)

Step-5 : Add up the four terms of step 4 :

(4x-1) • (2x-5)

Which is the desired factorization

Final result : (2x - 5) • (4x - 1)
