Find the missing value
Answer:
-12
Step-by-step explanation:
Let's replace that blank with x for now ;)
x - (-5) = -7
First, let's change that -(-5) to +5 because subtracting negatives is the same as adding.
x + 5 = -7
Subtract five from each side.
x + 5 = -7
-5 -5
x = -12
So then we change that x back to the blank and fill it in with -12.

A company has beginning inventory of 20000, purchases of 15000, and ending of 2500. The cost of goods available for sale is?
Answer:
Maybe,2500. Is just my guessing.
Step-by-step explanation:
Cost of Goods Sold = Beginning Inventory + Purchases during the year - Ending Inventory
= 20,000 + 15,000 - 2,500
=35,000 - 2,500
=32,500

Solve 4x- c= k for x.
K + c
A. X =
*=***
B. x = 4(k-c)
C. x = 4(k+ c)
К-с
D. x.
Answer:
Step-by-step explanation:
Let's begin the solution by isolating the 4x term:
4x- c= k => 4x = c + k
Now divide both sides by 4:
c + k
x = --------------
4
This does not match Answer C, but would match Answer C if k + c were divided by 4. Answer C, as shown, is incorrect.

When Quinn got home, he turned the air conditioner on.
QQQ represents the temperature in Quinn's home (in degrees Celsius) after ttt minutes.
Q=42-0.7tQ=42−0.7tQ, equals, 42, minus, 0, point, 7, t
What was the temperature when Quinn returned home?
degrees Celsius
Answer:
It’s 42
Step-by-step explanation: when Quinn return home, it was 0 minutes he turned on the air conditioner. So temperature at that time is equal to value of Q when t=0
Q=42-0.7t
=42-0.7(0)
=42
Answer:
42

Evaluate each trigonometric equation for θ.
Answer:
sinФ = 8/17
cosФ = 15/17
tan Ф = 8/15
csc Ф = 17/8
sec Ф = 17/15
cot Ф = 15/8
Step-by-step explanation:
Let us revise the trigonometry functions
Sin(x) = opposite/hypotenuseCos(x) = adjacent/hypoteouseTan(x) = opposite/adjacentCsc(x) = hypotenuse/oppositSec(x) = hypotenues/adjacentCot(x) = adjacent/oppositeIn the given figure
The opposite side to angle Ф = 8
The adjacent side to angle Ф = 15
Find the hypotenuse using Pythagoras' theorem
[tex]Hypotenuse = \sqrt{8^{2}+15^{2} }[/tex]
[tex]Hypotenuse = \sqrt{64+225}[/tex]
[tex]Hypotenuse = \sqrt{289}[/tex]
[tex]Hypotenuse = 17[/tex]
Let us use the rules above to find the trigonometry functions
sinФ = 8/17
cosФ = 15/17
tan Ф = 8/15
csc Ф = 17/8
sec Ф = 17/15
cot Ф = 15/8

Determine the number of triangles ABC possible with the given parts.
b = 24, c = 29, B = 43°
9514 1404 393
Answer:
2
Step-by-step explanation:
In general, if the given angle is opposite the shorter of the two given sides, there will be 0 or 2 possible triangles. The attachments show the two possibilities.
__
There will be zero possible triangles if the ratio of sides is less than the sine of the angle. Here, 24/29 ≈ 0.8276, sin(43°) ≈ 0.6820. The ratio of sides is greater, so there are two possible triangles.
If the given angle is opposite the longer of the two given sides, there is one possible triangle. The same is true if the given angle is between the two given sides.
what’s the difference between 2.7 , 5.9 on a number line
Answer:
3.2
Step-by-step explanation:
5.9 - 2.7 = 3.2
**difference means subtract**
The difference is between 2.7 and 5.9 on a number line.
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.
Any directed number's location can be determined using a number line. There are positive and negative axes in it.
We have to determine the difference between 2.7 and 5.9 on a number line.
⇒ 5.9 - 2.7
Apply the subtraction operation between 2.7 and 5.9, and we get
⇒ 3.2
Therefore, the difference is between 2.7 and 5.9 on a number line.

What is the slope of the line for the situation below in decimal form?
Answer:
5/4
Step-by-step explanation:
The slope should be 5/4 because if you go to a point on the line where the boxes meet on your graph and connect it to another point, you can count. I like to use rise over run, meaning you count up or down until you get level with the point you're trying to reach, and the run is the left or right until you get to the point you need. I really hope this helped! It may seem confusing at first, but you got it!

Decrease 520 by 15% what Is the answer?
Answer:
442
Step-by-step explanation:
If you want to decrease 520 by 15%, you have to multiply 15% by 520 first, which is 78. Next, you have to minus 78 from 520. Now you get 442!
The number is 442 which is obtained after decreasing 520 by 15% the answer is 442.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Let x be the number that is obtained after decreasing 520 by 15%
= (100 - 15)% of 520
= 85% of 520
= 0.85×520
= 442
Thus, the number is 442 which is obtained after decreasing 520 by 15% the answer is 442.

This is a warmup for your first project. The drug valium is eliminated from the bloodstream through a decay process with a half-life of 36 hours. This means that no matter how much drug is in your body, 36 hours later, half will be left. An initial dose of 20 milligrams of valium is taken at midnight. This is actually a version of the mixing-tank problem with the tank representing the circulatory system. If we don’t know something, give it a name (e.g. flow in = rin). Assume that the volume of blood in a person does not fluctuate much, so we can assume it is a constant.
(a) Define your dependent and independent variable with units. Typical volume units for blood is in terms of Liters.
(b) What is the flow rate in? flow rate out? concentration going in? concentration going out? initial condition?
(c) Write the initial value problem (IVP).
(d) Solve your initial value problem.
(e) Use information given to you to determine all constants in your solution.
(f) What is the amount of valium in your body at noon the next day? How long does it take for the drug to reach 10% of its initial level?
Step-by-step explanation:
a. We have v as the amount of drug(mg) in the blood at time t (hrs)
b. Flow rate in = k litre/he
For a circulatory system we have the flow rate in and flow rate out to be the same
Therefore,
Flow rate out = k litre/hr
concentration of drug going in = 0mg/litre
Concentration of drug going out = v mg/litre
V(0) = 20mg since 20mg was taken at midnight
V(0) = 20
Half life t1/2 = 36 hours
V(36) = v(0)/2
= 20/2
= 10mg
C. [tex]ivp = \frac{dv}{dt}[/tex][tex]= -kv[/tex]
[tex]v(0) = 20mg\\v(36) = 10mg[/tex]
d. solution
[tex]\frac{dv}{dt} = -kt\\ln(v) = ln(c) - kt[/tex]
[tex]\frac{v}{c} = e^{-kt} = v=ce^{-kt}[/tex]
v(0) = 20
[tex]ce^{-k(0)} =20[/tex]
c = 20
so
[tex]v(t) = 20e^{-kt}[/tex]
e.
[tex]t\frac{1}{2}=36hours\\ v(36)= 10[/tex]
[tex]10 = 20e^{-36k}[/tex]
[tex]\frac{1}{2} =e^{-36k}[/tex]
we take log
[tex]k=\frac{ln(2)}{36}[/tex]

Two angles form a linear pair. One angle measures
2
x
and the other angle measures
10
x
. Find the measure of the smaller angle.
Answer:
30 degrees
Step-by-step explanation:
a linear pair adds up to 180 degrees. therefore, you can compose the equation 2x+10x=180
12x=180
x=15
the smaller angle is 2x, so 2 times 15 is 30

Find the following:
a. g(h(x))=_______
b. h(g(x))=_______
c. h(h(x))=_______
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
[tex]g(h(x)) = \sqrt[4]{x^2 + x +5} + 3[/tex]
b
[tex]h(g(x)) = \sqrt{x} + 7\sqrt[4]{x} + 17[/tex]
c
[tex]h(h(x)) = [x^2 + x + 5 ]^2 + x^2 + x + 10[/tex]
Step-by-step explanation:
From the question we are told that
[tex]h(x) = x^2 + x + 5[/tex]
and
[tex]g(x) = \sqrt[4]{x} + 3[/tex]
Considering first question
Now we are told g(h(x))
i.e
[tex]g(h(x)) = [x^2 + x + 5 ]^{\frac{1}{4} } + 3[/tex]
=> [tex]g(h(x)) = \sqrt[4]{x^2 + x +5} + 3[/tex]
Considering second question
Now we are told h(g(x))
i.e
[tex]h(g(x)) = [x^{\frac{1}{4} } + 3]^2 + x^{\frac{1}{4} } + 3 + 5[/tex]
=> [tex]h(g(x)) = x^{\frac{1}{2} } + 6x^{\frac{1}{4} } + 9+ x^{\frac{1}{4}} + 8[/tex]
=> [tex]h(g(x)) = x^{\frac{1}{2}} + 7x^{\frac{1}{4}} + 17[/tex]
=> [tex]h(g(x)) = \sqrt{x} + 7\sqrt[4]{x} + 17[/tex]
Considering third question
[tex]h(h(x))= [x^2 + x + 5]^2 + [x^2 + x + 5 ] + 5[/tex]
=> [tex]h(h(x)) = [x^2 + x + 5 ]^2 + x^2 + x + 10[/tex]
