Answer: 4 x 10^12

Step-by-step explanation: first you distribute the powers into tens. Any multiply 10 to the eighth power to six, and multiply 10 to the -4th power to 1.5. After that you divide the first number in parentheses by the second number in parentheses. This answer on a regular calculator would be 4+12 zeros. Thus creating the answer 4,000,000,000. Which is, simplified in scientific notation, 4×10 to the 12th power.

Answer:

x ≈ - 1.28

Step-by-step explanation:

Using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

Given

ln(x + 4) = 1 , then

x + 4 = [tex]e^{1}[/tex] ( subtract 4 from both sides )

x = [tex]e^{1}[/tex] - 4 = - 1.28 ( to the nearest hundredth )

Answer:

82 square feet.

Step-by-step explanation:

You count the amount of 1ft x 1ft squares in the diagram and multiply that number by itself.

Answer:

15.6 feet

Step-by-step explanation:

The total length of the two wires for planting the sapling is L = 15.6 feet

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the total length of the two wires for the sapling be L

Now , let the triangle be represented as ΔABC

where the base of the triangle BC = 5 feet

The height of the triangle AB = 6 feet

And , the hypotenuse of the triangle AC = length of one wire

So , L = 2 ( AC )

On simplifying , we get

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

The length of 2 wires = 2AC = 2√ ( AB )² + ( BC )²

The length of 2 wires = 2AC = 2√ ( 6 )² + ( 5 )²

The length of 2 wires = 2AC = 2√ ( 36 + 25 )

The length of 2 wires = 2AC = 2√61

On further simplification , we get

The length of 2 wires = 2AC = 2 x 7.8

The length of 2 wires = 2AC = 15.6 feet

Hence , the length of the wires for the sapling is 15.6 feet

Answer:

3/4 liter

Step-by-step explanation:

Kelly starts at 2 liters, then uses 1/2 liter in the morning, so we have 1 1/2 liters. Then, the rest is used for lunch and dinner, and both being the same amount, she used 3/4 liter of milk for dinner.

3/4 litres of milk used by her at dinner.

Kelly has 2 litres of milk in her refrigerator.

She used 1/2 litres of milk with the breakfast in morning.

Remaining milk in her refrigerator = (2- 1/2) litres = 3/2 litres

By the problem, She use the same quantities of milk at both lunch and dinner.

So, She use half of the remaining milk at dinner.

∴ The quantity of milk used by her at dinner = 1/2 of 3/2 litres

                                                                          = (1/2 × 3/2) litres

                                                                          = 3/4 litres

Answer:

Clue#1:  6x+4y=550

Clue #2:  1/2x+4y=1000

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

The first number will be x, and the second number y:

The sum of six times the first number and four times the second number is equal to 550

Six times the first number means that the first number must be multiplied by 6.(6x); the same for four times the second number (4x).

6x+4y=550

The sum of half the first number and four times the second number is equal to 1000

Half the first number means the first number (x) divided by 2,or multiplied by 1/2.  

1/2x+4y=1000

Answer:

Part B is 1/4

Step-by-step explanation:

From the letter a), we have 8 possible options. From these options, we have 2 that have turkey and ketchup (WTK and BTK), so the probability is the number of options we want over the total number of options:

P = 2/8 = 1/4

Types of sandwiches Hugo could make

a) WCK, WTM, WTK, BCM, BCK, BTM, BTK.

A fraction of the possible types of sandwiches have Turkey and Ketchup

b) 1/4

a) For this answer we just need to write all possibilities of sandwiches, so we can use the options given to create all the sandwiches, besides the one given:

(WCM given), WCK, WTM, WTK, BCM, BCK, BTM, BTK.

b) From the letter a), we have 8 possible options. From these options, we have 2 that have turkey and ketchup (WTK and BTK), so the probability is the number of options we want over the total number of options:

Answer:

Choice A (x=5)

Step-by-step explanation:

You can get you answer either by using the 3-4-5 Triangle Rule or the Pythagorean theorem ([tex]a^{2} +b^{2} =c^{2}[/tex])

Using the Pythagorean theorem:

Begin by plugging in 4 into a and 3 into b

[tex]4^{2} +3^{2} =c^{2}[/tex]

[tex]16 +9 =c^{2}[/tex]

[tex]c^{2}= 25[/tex]

Then, find the square root of each side

[tex]\sqrt{c^{2} } =\sqrt{25}[/tex]

[tex]c =5[/tex]

Choice A (x = 5) is your answer

Answer:

A. x=5

Step-by-step explanation:

This triangle is a right triangle. We know this because of the little square in the corner that represents a right angle. Therefore, we can use Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex]

where a and b are the legs and c is the hypotenuse.

We know that 4 and 3 are the legs, because they form the right angle. We also know that x is the hypotenuse, because it is opposite the right angle.

a=4

b=3

c=x

Substitute these values into the formula.

[tex]4^2+3^2=x^2[/tex]

Evaluate the exponents.

4^2 is the same as 4*4, which is 16.

3^2 is the same as 3*3, which is 9.

[tex]16+9=x^2[/tex]

Add 16 and 9.

[tex]25=x^2[/tex]

We are trying to find x, which means we have to get x alone. x is currently being squared. To undo this, take the square root of both sides. The exponent and square root will cancel, leaving x by itself.

[tex]\sqrt{25}=\sqrt{x^2}[/tex]

[tex]\sqrt{25}=x[/tex]

[tex]5=x[/tex]

Therefore the correct answer is A: x=5

Answer:

Indirect Variation

Step-by-step explanation:

Answer:

3x - 4y = - 12

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Calculate the equation in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = [tex]\frac{3-0}{0+4}[/tex] = [tex]\frac{3}{4}[/tex]

The line crosses the y- axis at (0, 3) ⇒ c = 3

y = [tex]\frac{3}{4}[/tex] x + 3 ← in slope- intercept form

Multiply through by 4

4y = 3x + 12 or

3x + 12 = 4y ( subtract 12 from both sides )

3x = 4y - 12 ( subtract 4y from both sides )

3x - 4y = - 12 ← in standard form
