Answer: BOTTLE 1 =0.0297 BOTTLE 2 =0.0289

Step-by-step explanation:

In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50 km is covered in 5.5 hours, the unit rate will be 50 km/5.5 hours = 9.09 km/hour

bottle 1: $2.97/100 oz = unit rate

bottle 2: $5.78/200 oz=unit rate

BOTTLE 1 =0.0297

BOTTLE 2 =0.0289

Answer:it is 3 to 4

Step-by-step explanation:

This is correct

The ratio of the edge lengths of the two cubes is 7 : 9.

The surface area of the cube can be defined as the total area covered by all six faces of the cube.

Given

The surface areas of two cubes have a ratio of 49 to 81.

Formula of surface area of cube = 6[tex]a^{2}[/tex]

Surface area of cube 1 = [tex]6a^{2} _{1}[/tex]

Surface area of cube 1 = [tex]6a^{2} _{2}[/tex]

Surface areas of two cubes have a ratio of 49 to 81.

[tex]\frac{6a^{2} _{1} }{6a^{2} _{2}}=\frac{49}{81}[/tex]

⇒  [tex]\frac{a^{2} _{1} }{a^{2} _{2}}=\frac{49}{81}[/tex]

⇒ [tex](\frac{a_{1} }{a_{2} } )^{2} =\frac{49}{81}[/tex]

⇒ [tex]\frac{a_{1} }{a_{2} } =\sqrt{\frac{49}{81} }[/tex]

⇒ [tex]\frac{a_{1} }{a_{2} } =\frac{7}{9} }[/tex]

⇒ [tex]a_{1}:a_{2} = 7:9[/tex]

Hence, the ratio of the edge lengths of the two cubes is 7 : 9.

Answer:

124.80 ft

Step-by-step explanation:

Height of Daniel = 6 ft

The angle of elevation from his eyes to the top of the statue is = 68°

Daniel is 48 ft away from the base of the statue

To find the height of the statue apply the tangent of an angle formula then add height of Daniel as;

Tan 68° = h/48

h= {48 tan 68°} + 6 ft

h= 124.804168964

h= 124.80 ft

Answer:

The answer is C, The domain is a set of real numbers, and the range is y>0.

Step-by-step explanation:

If you recall from the instruction, the domain has to be whole numbers, because of it is not then the function will decrease into fractions never quite reaching zero. X has to be a real number, because it cannot be a fraction to keep an increasing rate, making the domain all real numbers. The range can never hit 0, so that means y>0.

Based on the values of the ordered pairs in the table of the exponential function, the domain is a set of real numbers, and the range is y>0.

The domain of a function refers to the set of possible input values.

For a graph, the domain refers to the set of possible input values shown on the x-axis.

The range of a function is the set of possible output values.

For a graph, the range is the set of possible output values shown on the y-axis.

Answer:

C) $6.46

Step-by-step explanation:

Equations

The price per gallon of milk (m) and the price per gallon of orange juice (j) are given below:

m = 5.71 + 0.25n

j = 4.66 + 0.60n

Where n is the number of months after December 31, 2018.

It's required to find the value of n when both prices are equal:

4.66 + 0.60n = 5.71 + 0.25n

Subtracting 0.25n:

4.66 + 0.60n - 0.25n = 5.71

Subtracting 4.66:

0.60n - 0.25n = 5.71 - 4.66

Operating:

0.35n = 1.05

n = 1.05/0.35

n = 3

The price per gallon of milk for n=3:

m = 5.71 + 0.25*3

m = 5.71 + 0.75

m = $6.46

Step-by-step explanation:

Use the form y = mx + b for your answer.  Since 32 is the starting point, it will represent b.  b represents the y intercept.  Since the temperature decreases every hour, the second part of the equation would -2h.  So, if you put it together, the final equation is y = -2h + 32.

Width of frame on all sides = x

Painting and frame takes the shape of a rectangle :

Area of rectangle = Length * Width

Area of painting = (30 * 17)

Area of frame ;

Length = (x + x) = 2x ;

Width = (x + x) = 2x
