Answer:

kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation

Step-by-step explanation:

8.912 times 10 superscript 5 is written is scientific notation

The true statement about Kailey's expression is (a) Kailey is not correct: 89.12 * 10 ^5 is not written in scientific notation.

From the question, Kailey's expression can be represented as:

8,912,000 = 89.12 * 10^5 in scientific notation

To check if Kailey's expression is correct, we count the number of zeros in the number up to 8.9

The number of zero is 6.

So, the scientific notation of the number is

8,912,000 = 8.912 * 10^6

This means that Kailey's expression is not correct

Hence, the true statement is (d)

Answer: IT IS 5 17/21

Step-by-step explanation:

I used a calculator

Answer:

5 17/21  >  5 12/25          

Step-by-step explanation:

Problem 1

Answer: x = 9

----------

Explanation:

For now focus on triangle DEF. We need to find the missing angle D.

D+E+F = 180

D+71+42 = 180

D+113 = 180

D = 180-113

D = 67

In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent

Let's see what happens when we force them to be equal

angle EDF = angle GHF

67 = 5x+22

67-22 = 5x

45 = 5x

5x = 45

x = 45/5

x = 9

Problem 2

Answers:

Converse: "if it is winter, then it is snowing"

Inverse: "If it is not snowing, then it is not winter"

Contrapositive: "If it is not winter, then it is not snowing"

----------

Explanation:

The original conditional is in the form "If P, then Q". The P and Q are placeholders for logical statements.

We then have the following forms

==========================================

Problem 3

Answer: choice B) "If the sum of two angles is not 180 degrees, then they aren't supplementary"

----------

Explanation:

Refer to problem 2 for the general form of the inverse. We negate each of the P and Q to get our final answer.

==========================================

Problem 4

Answer: Choice C) "If I do not need an umbrella, then it is not raining"

----------

Explanation:

Refer to problem 2 for the general form of the contrapositive. We swap P and Q, and negate each.

==========================================

Problem 5

Answer: Choice A) "If two lines have opposite slopes, then they are perpendicular"

----------

Explanation:

Refer to problem 2 for the general form of the converse. We swap the positions of P and Q.

Answer: 2.852 × 10-1

Step-by-step explanation:

7.13 x 10^-3 =  0.00713

0.00713 x 40 = 0.2852

0.2852 = 2.852 × 10-1

Answer:

Answer: 2.852 × 10-1

Step-by-step explanation:

7.13 x 10^-3 =  0.00713

0.00713 x 40 = 0.2852

0.2852 = 2.852 × 10-1

Answer:

[tex] 6.4 * 10^{3} km[/tex]

Step-by-step explanation:

Scientific notation can be defined as a way of expressing and writing a very small or large real number in decimal form. Generally, to use the scientific notation, we will multiply the real number by a power of 10.

Given that the length of Amazon River is 6,400 kilometers.

[tex] \frac{6400}{1000} = 6.4[/tex]

[tex] 1000 = 10^{3}[/tex]

Therefore,

6, 400 kilometers = 6.4 × 10³ kilometers.

Step-by-step explanation:

Answer:

<6 = 68

Step-by-step explanation:

<5 + <6 + 90 = 180  since the 3 angles form a straight line

22 + <6 + 90 =180

Combine like terms

112+ <6 = 180

Subtract 112 from each side

<6 = 180-112

<6 =68

Answer:

m 1= 113 i think :)

Step-by-step explanation:

180 - 67

Answer:

it should total 180 degrees

so 160-67 is 113

Answer:

f(x) = - [tex]\frac{1}{2}[/tex] x

Step-by-step explanation:

The standard form for a linear function is

f(x) = ax + b

Using the given values f(- 4) = 2 and f(6) = 3 , then

- 4a + b = 2 → (1)

6a + b = - 3 → (2)

Subtract (2) from (1) term by term to eliminate b

- 10a = 5 ( divide both sides by - 10 )

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

Substitute a = - [tex]\frac{1}{2}[/tex] into either of the 2 equations and solve for b

Substituting into (1)

2 + b = 2 ( subtract 2 from both sides )

b = 0

Thus the linear function is

f(x) = - [tex]\frac{1}{2}[/tex] x

The linear function is f(x) = -0.5x

For f(-4) = 2

x₁ = -4, y₁ = 2

For f(6) = -3

x₂ = 6, y₂ = -3

The slope(m) is found using the formula

m = (y₂ - y₁)/(x₂ - x₁)

m = (-3-2)/(6-(-4))

m = -5/10

m = -0.5

Substitute m = -0.5, x₁= -4, and y₁ = 2 into the equation below:

y - y₁ = m(x - x₁)

y - 2 = -0.5(x - (-4))

y - 2 = -0.5(x + 4)

y - 2 = -0.5x - 2

y = -0.5x - 2 + 2

y = -0.5x

Therefore, the linear function is f(x) = -0.5x
