The temperature is 56°F. The temperature decreases for 6 hours. Each hour, the temperature decreases by 3°F. Then the temperature rises 12°F in one hour. What is the temperature after 7 hours?
Answer:
50 degrees
Step-by-step explanation:
3 x 6 = 18
56 - 18 = 38
38 + 12 = 50
First answer is brainiest
Explain you're answer even if its just a bit because I'm tired of people giving me random answers so I fail its annoying.
Answer:
D
Step-by-step explanation:
So you are looking for the inverse equation. The original can be written as y=1/2x-6. For the inverse, your variables switch places. It's reflecting across the line y=x (that's what the inverse does). So you write it as x=1/2y-6. Now solve for the new equation:
Move 6 over: x+6=1/2y
Isolate y: 2(x+6)=y
This gets you D.

Angle W measures 68 degrees more than angle F. Angles Wand
Fare supplementary. What is the measure of angle W?
Answer: The measure of angle W is 124°.
Step-by-step explanation:
Given: Angles W and F are supplementary.
We know that the sum of two supplementary angles is 180 degrees.
So, ∠W + ∠F = 180° (i)
As per given,
∠W = ∠F + 68° (ii)
Put value of ∠W from (ii) in (i)
∠F + 68°+∠F = 180°
⇒ 2 ∠F = 180°- 68°
⇒ 2 ∠F = 112°
⇒ ∠F = 56°
From (ii),
∠W = 56° + 68°
⇒ 124°
Hence, the measure of angle W is 124°.

2.5 divided by 1.5 round to nearest tenth
Answer:
1.7
Step-by-step explanation:
2.5÷1.5
5/3
1.66666
1.7
The divisions of 2.5 divided by 1.5 gives to 5/3 or 1.6667.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things.
Given:
2.5 divided by 1.5
So, 2.5 / 1.5
= 25 x 10 / 15 x 10
= 25/15
= 5 x 5 / 5 x 3
= 5/3
Hence, the divisions results to 5/3 or 1.6667

Any hypothesis that an analyst has accepted to be true and which forms the basis of an assessment is a: ______
Answer:
The correct answer is the alternate hypothesis.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
Thus, the correct answer is the alternate hypothesis.

A board 14 1/4 inches long is cut from a board that is 4 feet long. If the width of the saw cut is 1/8 inch, what is the length of the remaining piece?
Answer:
Step-by-step explanation:
From the given information;
since;
1 feet = 12 inches long
Then, 4 feet = (4 × 12)inches long
= 48 inches long
Thus, the length of the remaining piece is calculated as follows:
Length of remaining piece = Total length of piece - (piece that was being cut + width )
[tex]= 48 - (14 \dfrac{1}{4}+ \dfrac{1}{8})[/tex]
[tex]= 48 - ( \dfrac{57}{4}+ \dfrac{1}{8})[/tex]
[tex]= 48 - ( \dfrac{114+1}{8})[/tex]
[tex]= 48 - ( \dfrac{115}{8})[/tex]
[tex]= \dfrac{269}{8}[/tex] inches

What is the absolute value of the complex number 4-V3/?
O 32
O 14
O 18
Answer:
[tex]3\sqrt{2}[/tex]
Step-by-step explanation:
The Magnitude of a Complex Number
A complex number is expressed in rectangular form as:
[tex]Z=a+ b\mathbf{ i}[/tex]
The absolute value or magnitude of Z is calculated as follows:
[tex]\mid Z\mid=\sqrt{a^2+b^2}[/tex]
We are given the number
[tex]Z=-4-\sqrt{2}\mathbf{ i}[/tex]
Here: a= -4, b=[tex]-\sqrt{2}[/tex]
Calculating the absolute value:
[tex]\mid Z\mid=\sqrt{(-4)^2+(-\sqrt{2})^2}[/tex]
Operating:
[tex]\mid Z\mid=\sqrt{16+2}=\sqrt{18}[/tex]
Factoring 18:
[tex]\mid Z\mid=\sqrt{3^2*2}[/tex]
Taking the square root of 3^2:
[tex]\mid Z\mid=3\sqrt{2}[/tex]
Answer: [tex]\mathbf{3\sqrt{2}}[/tex]

So, I am solving your concept based on an assumed graph which I have attached. It would anyways clear your concept.
Answer:
Please check the explanation!
Step-by-step explanation:
Given the attached graph below, it is clear that the right angle triangle ABC is shown.
Here are some of the information we can get from the right angle triangle ABC such as:
The angle at C = 30°side AB = 8 unitsWe have to determine the unknown side 'x' using the trigonometric ratios
As
tan Ф = opp/adjacent
From the diagram it is clear that
Ф = 30°
opp=8
adjacent = BC = x
so
tan Ф = opp/adjacent
tan 30 = 8/x
1/√3 = 8/x
x = 8×√3
x = 13.9
Therefore, the missing length will be: x = 13.9
