Find the radian measure of an angle of -280 degrees

Answers

Answer 1

Answer: -4.88691778Solution:1.Write down the number of degrees you want to convert to radians Given Degree = -280° The formula to convert degrees to radian measure is:Radian = degree x π/180 2. Multiply the number of degrees by π/180. Think of it like multiplying two fractions: the first fraction has the number of degrees in the numerator and "1" in the denominator, and the second fraction has π in the numerator and 180 in the denominator. -280 x π/180 = -280π/1803. Find the largest number that can evenly divide into the numerator and denominator of each fraction and use it to simplify each fraction. The largest number for 280 is 20.-280 x π/180 = -280π/180 ÷ 20/20 = -14π /9 4. Then multiply the numerator by 3.14159 because pi or π is equivalent to 3.14159, -14x 3.14159= -43.982265. To get the radian measure, we will divide -43.98226 by 9. -43.98226/9= -4.88691778

Answers

The half life is 78 hours and the amount after 78 hours is 395 kg hence time constant is 395 = 790 * e^(p*78) By taking 790 common and natural log on both side ln (395 / 790) = (p*78) -0.6931 = 78*p -0.0088 = p (or -0.88%) Material left after 18 hours is A(18) = 790 * e^(-0.0088*18) A = 673.301 kg

Kareem wants to wallpaper the back wall of his bedroom. The wall is in the shape of a rectangle. Its length is
13 feet and its width is 12
feet. The wallpaper costs $8
for each square foot. How much will wallpaper cost for the wall?

Answers

The first step in solving this problem is to compute for the area of the rectangular wall. The formula in computing the area of a rectangle is:

A = LW

Substituting the given measurements in the problem to the formula:

A = 13 (12)

A = 156

Therefore, the area of the wall is 156 square feet. To compute the wallpaper cost of the wall, you have to multiply the cost per square foot to the total area.

$8 per square foot x 156 square feet = $1,248

Therefore, the wallpaper cost for the wall is $1,248

Factored Form is (x+4)(x+2)
Expanded Form is x^2+6x+8

----------------------------------------------------------
----------------------------------------------------------

Explanation:

The factored form is simply a matter of reading off the values from the given image. There isn't much work to show here.
Along the left side we have x and 4 so x+4 is one of the factors. Along the bottom we have x and 2, so x+2 is another factor
The two factors are (x+4) and (x+2) so that's why the factored form is (x+4)(x+2)

-------------------------------

Let's expand out the factored form

The overall rectangle is broken up into four parts. I'll label the four smaller rectangles as...

Rectangle A in the upper left corner (this rectangle is x by x)
Rectangle B in the upper right corner (this rectangle is 2 by x)
Rectangle C in the lower left corner (this rectangle is x by 4)
Rectangle D in the lower right corner (this rectangle is 2 by 4)

The idea is that adding the areas of rectangles A through D leads us to the overall area for this largest rectangle.

Area of Rectangle A = (length)*(width) = x*x = x^2
Area of Rectangle B = (length)*(width) = 2*x = 2x
Area of Rectangle C = (length)*(width) = x*4 = 4x
Area of Rectangle D = (length)*(width) = 2*4 = 8

Notice we have the like terms 2x and 4x (areas of rectangle C and D respectively). They combine to 2x+4x = 6x

So after adding all the individual areas and combining like terms, we arrive at the fully expanded form of x^2+6x+8

solve the system by either elimination or substitution

Answers

The correct answer is A: x=2 and y=-3. Either method would work, but for example, let's use elimination. If you multiply the second equation by 5, you get: 10x +5y = 5. When you add both equations, you can then cross out both y terms. You are left with one equation that reads: 13x=26. Solving for x gives you 2. You can substitute 2 in for x in either equation and you will receive -3 for your y value.

answer
5 units

Final answer:

The value of x can signify diverse number based on the context it is applied in. For instance, it can be a certain range of values, part of a chemical equation, or the result of a mathematical equation. Therefore, the value of x is determined by the given conditions.

Explanation:

The value of x can be discovered through various mathematical processes depending on the context. In the examples given, x was used to denote different values across multiple scenarios.

One situation presented x as a value that ranged from 1.5 to 4.5, indicated by 1.5 ≤ x ≤ 4.5. In another instance, x was determined by the concentration of hydroxide ions in a chemical equation, which resulted in x = 4.0 × 10-³ M. Furthermore, x was also inferred from a quadratic equation where it implied the hydronium concentration.

In summary, the value of x varies based on the mathematical or scientific context it is applied to, and its value must be determined through specified conditions or equations.

List the angles of triangle DEF in order from smallest to largest measure if DE = 7, EF = 9, and DF = 3.

∠D, ∠F, ∠E

Answers

The angles in order from smallest to largest would be ∠E, ∠F, ∠D.

∠D is opposite side EF. ∠E is opposite side DF. ∠F is opposite side DE. The sides that are the smallest correspond with the smallest angles, and the sides that are the largest correspond with the largest angles.

Answer: The order from smallest to largest is <E, <F, <D

First, you should draw a picture of triangle DEF and label all of the sides. Then, you will have an idea of what the triangle looks like and the relative size of the angles.

You can also look at the side opposite of the angle. The larger the opposite side, the larger the angle.

AD←→ is tangent to circle M at point D. The measure of ∠DMQ is 50º.

What is the measure of ∠DQM?

Answers

Answer:

Hello! I just completed the quiz :))

Step-by-step explanation:

This is for more confirmation (´｡• ᵕ •｡`) ♡ glad I could help!

Tangent is a straight line that touches the circle at any point on the curve. The measure of ∠DQM in ΔDQM is 40º.

What is a tangent?

A tangent is a straight line that touches the circle at any point on the curve. And the angle made by the tangent with radius is always 90°.

We know that line AD is the tangent to circle M, and line MD is the radius of the circle, therefore, the measure of ∠ADM is 90°.

Now, In ΔDQM, the measure of ∠DMQ is 50º, while the measure of ∠MDQ is 90º. therefore, the sum of all the angles of the ΔDQM can be written as,

[tex]\angle DQM + \angle MDQ + \angle DMQ = 180^o\\\\\angle DQM + 90^o + 50^o = 180^o\\\\\angle DQM = 180^o -90^o -50^o\\\\\angle DQM = 40^o[/tex]

Hence, the measure of ∠DQM is 40º.

What is measure of angle P?

Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.

Answers

Sin P = opp/hyp
sin P = 15/17
P = sin⁻¹(15/17)
P = 61.93° (nearest hundredth)

Answer:

The measure of angle P is 61.93°

Step-by-step explanation:

We are given a right triangle with measures 8 cm, 15 cm and 17 cm.

For angle P, we see that,

Perpendicular = 15 cm

Hypotenuse = 17 cm

Using the trigonometric forms of the angles, we have,

[tex]\sin P=\frac{Perpendicular}{Hypotenuse}[/tex]

i.e. [tex]\sin P=\frac{15}{17}[/tex]

i.e. [tex]\sin P=0.88235[/tex]

i.e. [tex]P=\arcsin 0.88235[/tex]

i.e. P = 61.93°

Hence, the measure of angle P is 61.93°.

c= number of crickets
g= number of grasshoppers= twice number of crickets= 2c
T= total number of both= 561

If you add the number of crickets and the number if grasshoppers, you'll get a total of 561.

c + g= T
c + g= 561

Now we also know that grasshoppers are 2c (twice the crickets). Substitute 2c for g in the equation to solve for c.

c + g= 561
c + 2c= 561
combine like terms
3c= 561
divide both sides by 3
c= 187 crickets

Substitute number of crickets back in equation to find g.

c + g= 561
187 + g= 561
subtract 187 from both sides
g= 374 grasshoppers

CHECK:
Since grasshoppers are twice the number of crickets, then multiplying the number of crickets by two should equal the number of grasshoppers.
187 * 2= 374
374= 374

ANSWER: 187 crickets and 374 grasshoppers

Lyle deposited a check for $75.26. He’ll use the check register to record his transaction. What will be his new balance?

Answers

Answer

$896.44

Explanation

Remember that to get the current balance, you subtract all the debits from balance and add all the deposits to it.

We know from our table that the first transaction is medical bill, which is debit, so we are going to subtract the medical bill from the balance to find the balance at that point in time.

Balance = $862.74 - $41.56 = $821.18

We also know that the second transaction is a check deposit for $75.26, so to find the current balance, we just need to add $75.26 to our previous balance.

Current balance = $821.18 + $75.26 = $896.44
