Kobe drinks 1/3 cups of juice each day. He has 2 1/3 cups of juice left. For how many days will it last?
Answer:
Our juices’ journey to your table starts on the thousands of acres of citrus farms dotting Western North America. The process begins when the fruit is harvested at its sweetest, then sent to our plant to be pressed and bottled. From the plant, our juice is sent to retailers throughout the West, including Ralph’s, Bristol Farms and Pavilions to name a few. This lateral integration gets the freshest, best tasting juices to our customers as quickly as possible, and makes Perricone Farms a true “Farm-Bottle-Table” company. You’ll taste the difference with every sip.
Find the measure CAG
The answers:
a: 44°
b: 108°
c: 54°
d: 22°
Correct option is C, The measure of angle ∠CAG = 54°.
The length of the sides distinguishes triangles of the scalene, isosceles, and equilateral kinds. If the lengths of the three sides are all different, the triangle is a scalene triangle. A triangle that has equal lengths on each of its three sides is said to be isosceles.
Angles in a triangle Properties Triangle The theorem of sums. The sum of the three angles in a triangle is always 180 degrees.
The sum of an inside angle and the adjacent outer angle is 180 degrees.
According to the external angle theorem, the exterior angle of a triangle is equal to the sum of its two opposite interior angles.
Given that G is the triangle's center, all lines that emerge from it divide the angles equally.

⇒ X=6
⇒ 3(6)+4= 5(6)-8
⇒ 18+4 30-8
⇒ 22 = 22
⇒ 22+22
⇒ 44
The measure of the angle ∠BCA = 14 + 14 = 28°
The measure of the angle ∠BAC = 180 - (44 + 28)
⇒ 108
The measure of ∠ GAC = 1/2 (∠BAC) = 54°

"What is the rest wavelength of an emission line observed at 2148 nanometers in a galaxy 100
Megaparsecs away from the Milky Way? Your answer should be significant to four digits."
The rest wavelength of the emission line observed at 2148 nanometers in the galaxy 100 million light-years away is approximately 2103 nanometers.
The rest wavelength of an emission line can be determined by applying the concept of redshift, which is a phenomenon observed in astrophysics where light from distant objects is shifted towards longer wavelengths due to the expansion of the universe.
In this case, the emission line is observed at 2148 nanometers (or 2.148 micrometers) in a galaxy located 100 million light-years away. To calculate the rest wavelength, we need to consider the redshift factor. Redshift, denoted by z, is defined as the observed wavelength divided by the rest wavelength minus 1.
Given that the observed wavelength is 2.148 micrometers and the galaxy is located 100 million light-years away, we need to convert the distance into a redshift factor using the cosmological relationship between redshift and distance. Assuming a standard cosmological model, we can use the Hubble constant to estimate the redshift.
The Hubble constant represents the rate at which the universe is expanding. Taking a typical value of the Hubble constant as 70 kilometers per second per megaparsec, we find that the redshift factor, z, is approximately 0.021.
To determine the rest wavelength, we rearrange the redshift equation as \((observed wavelength) = (1 + z) \times (rest wavelength)\). Substituting the values, we get \((2.148 micrometers) = (1 + 0.021) \times (rest wavelength).\)
Simplifying the equation, we find the rest wavelength to be approximately 2.103 micrometers or 2103 nanometers.

What is the length of side CB to one decimal place?
B

53°
C
▸
The length of side CB to one decimal place is 89.3.
To find the length of side CB in the given triangle, we can use the sine rule. The sine rule states that in a triangle, the ratio of the length of a side to the sine of its opposite angle is constant.
In this case, we have the angle C as 53° and the side opposite to it, side CB, as the unknown. Let's denote the length of side CB as x.
According to the sine rule:
sin(C) / x = sin(A) / AB
We know that angle A is 37° and AB is 120 units. Plugging in the values:
sin(53°) / x = sin(37°) / 120
To find x, we can rearrange the equation:
x = (120 * sin(53°)) / sin(37°)
Calculating this expression gives us:
x ≈ 89.32
Rounding this value to one decimal place, the length of side CB is approximately 89.3.

What are the key concepts of Trigonometry?
SOLUTION
Step 1: Definition of Trigonometry
Trigonometry is one of the important branches in the history of mathematics that deals with the study of the relationship between the sides and angles of a right-angled triangle. In trigonometry, the angles can be either measured in degrees or radians. Some of the most commonly used trigonometric angles for calculations are 0°, 30°, 45°, 60° and 90°.
Step 2: State the three trigonometric ratios
The trigonometric ratios of a triangle are also called the trigonometric functions. Sine, cosine, and tangent are 3 important trigonometric functions and are abbreviated as sin, cos and tan.
Step 3: Show how these ratios or functions, evaluated in case of a right-angled triangle.
Consider the right-angled triangle above, where the longest side is called the hypotenuse, and the sides opposite to the hypotenuse are referred to as the adjacent and opposite sides.
\(\begin{gathered} \sin \theta=\frac{\text{opposite}}{\text{hypotenuse}} \\ \cos \theta=\frac{\text{adjacent}}{\text{hypotenuse}} \\ \tan \theta=\frac{\text{opposite}}{\text{adjacent}} \end{gathered}\)STEP 4: Evaluate the other 3 ratios that can be derived from the given ratios in step 3
\(\begin{gathered} co\sec \theta=\frac{1}{\sin \theta}=\frac{1}{\frac{\text{opposite}}{\text{hypotenuse}}}=\frac{\text{hypotenuse}}{\text{opposite}} \\ \sec \theta=\frac{1}{\cos \theta}=\frac{1}{\frac{\text{adjacent}}{\text{hypotenuse}}}=\frac{\text{hypotenuse}}{\text{adjacent}} \\ \cot \theta=\frac{1}{\tan \theta}=\frac{1}{\frac{\text{opposite}}{\text{adjacent}}}=\frac{\text{adjacent}}{\text{opposite}} \end{gathered}\)Knowing .these ratios are the basic concepts of Trigonometry.

What is the range of the function
Answer:
\(\{ y\; |\; 0 \leq y < 9 \}\)
Step-by-step explanation:
The range of a function is the set of all possible output values (y-values).
From inspection of the given graph:
Minimum value of y = 0Maximum value of y = 9As there is an open circle where y = 9, this means the value is not included in the range.
Therefore, the range of the function is:
\(\{ y\; |\; 0 \leq y < 9 \}\)
A cylinder has a height of 12 inches. A similar cylinder has a height of 15 inches. What is the ratio of the surface area of the larger cylinder to the surface area of the smaller cylinder?
The ratio is 15+\(r_2\) : \(12+r_1\).
What is surface area?
A three-dimensional object's surface area is the space it takes up when viewed from the outside.
Here surface area of the cylinder = \(2\pi rh+2\pi r^2\) square unit
=> A = \(2\pi r(h+r)\) square unit.
Now Height = 12 in , radius = r1 then,
=> \(A_1 = 2\pi r_1(12+r_1)\) -----> 1
Now Height = 15 in , radius = r2 then,
=>\(A_2=2\pi r_2(15+r_2)\)-------> 2
Now the ratio of the surface area of the larger cylinder to the surface area of the smaller cylinder then,
=>\(2\pi r_2(15+r_2) : 2\pi r_1(12+r_1)\)
=>\(15+r_2:12+r_1\)
Hence the ratio is \(15+r_2:12+r_1\).

Hello !

Example:
3x² + 7x - 2 = 0 is a quadratic equation.

= (-7 ± √(7² - 4*3*(-2))) / (2*3)

Write 7.03 x 10-3 as an ordinary number
Answer: 0.00703
Step-by-step explanation: The ordinary number, or standard form, of this expression would be 0.00703 because here, we are multiplying 7.03 in scientific notation by a power of ten that is negative. If any exponential power of 10 is being multiplied and is negative, the digits move that same number of places to the right of the decimal point to render a smaller number than it was in the expression.

Write an equation for the line parallel to the line -7x - 7y= 7 through the point (-1,2)
Answer:
\(y=-x+1\)
Step-by-step explanation:
Slope-Intercept Formula:It helps to write the equation in slope-intercept formula to find the slope of an equation in the form: \(y=mx+b\) where "m" is the slope of the equation. We can take the equation given: \(-7x-7y=7\) and solve for "y" to get the equation in slope-intercept form:
\(-7x-7y=7\)
add 7x to both sides:
\(-7y=7x+7\)
Divide both sides by -7
\(y=-x-1\)
Now in this form we can tell that the coefficient of "x" (the m value) is our slope, which is -1. We need this slope to determine a parallel line as parallel lines share the same slope but different y-intercepts. So a general equation for a parallel line would be:
\(y=-x+b\text{ where b }\ne -1\)
We're given the point (-1, 2) and we can use it to solve for that "b" value.
We plug in -1 as x and 2 as y
\(2=-1(-1)+b\implies 2=1+b\implies 1=b\)
Now we just plug this into the general equation to get: \(y=-x+1\)
