A 20-ounce box of cereal costs $3.20. A 12-ounce box of cereal costs $1.80. Which box of cereal is the better buy?

Answer:

a. p = 6

b. q = 4

c. r = 8

d. s = 10; t = 8.3

Step-by-step explanation:

1. a. The side length of two similar triangles are proportional, therefore:

[tex] \frac{9}{p} = \frac{15}{10} [/tex]

Cross multiply

[tex] 15*p = 10*9 [/tex]

[tex] 15*p = 90 [/tex]

Divide both sides by 15

p = 6

b. Based on the midsegment theorem,

[tex] q = \frac{1}{2}(8) [/tex]

[tex] q = 4 [/tex]

c. The side length of two similar triangles are proportional, therefore:

[tex] \frac{4}{10} = \frac{r}{20} [/tex]

Multiply both sides by 20

[tex] \frac{4}{10} \times 20 = \frac{r}{20} \times 20 [/tex]

[tex] \frac{80}{10} = r [/tex]

r = 8

d. The side length of two similar triangles are proportional, therefore:

[tex] \frac{9 + 6}{9} = \frac{s}{6} [/tex]

[tex] \frac{15}{9} = \frac{s}{6} [/tex]

Multiply both sides by 6

[tex] \frac{15}{9} \times 6 = \frac{s}{6} \times 6 [/tex]

[tex] \frac{15 \times 6}{9} = s [/tex]

s = 10

[tex] \frac{9 + 6}{9} = \frac{t}{5} [/tex]

[tex] \frac{15}{9} = \frac{t}{5} [/tex]

Multiply both sides by 5

[tex] \frac{15}{9} \times 5 = \frac{t}{5} \times 5 [/tex]

[tex] \frac{15 \times 5}{9} = t [/tex]

t = 8.3 (nearest tenth)

Answer:

5ft

Step-by-step explanation:

Given parameters:

Length of the pool  = 25ft

Width of the pool  = 15ft

Volume of water the pool can hold = 1875ft³ of water

Unknown:

Depth of the pool = ?

Solution:

The pool is in the shape of a cuboid.

The volume of a cuboid is given as;

        Volume of a cuboid  = L x width x depth

Insert the parameters and solve for the depth;

        1875  = 25 x 15 x depth

         depth = [tex]\frac{1875}{25 x 15}[/tex]   = 5ft

Answer:

y=-2x+2

Step-by-step explanation:

The slope is -2x, meaning that the y-intercept can be found by working backwards from the given point. If the y value of the point is 4, subtracting 2 to get you to the point (0, 2) would provide the y-intercept.

Slope Intercept form is y=mx+b (m is the slope, x is the entered value, b is the y intercept)

Answer:

The line y=-1 is a horizontal line and thus is a line that is parallel to the x-axis. If we reflect about a line that is parallel to the x-axis, then the x-coordinate of the point (that is reflected) will remain the same, thus the image of (2,-4) has x-coordinate 2 and thus the point is of the form (2,b).

Answer:

15w+5

How I did it:

add 2 and 13 and put the "w" after the answer which is 15. Then add 4 and 1. That is 5 so then it is 15w+5.

The simplified Expression of 2w+4+13w+1 is 5 ( 3w+ 1).

The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms.

i.e., A ( B+ C) = AB + AC.

Given:

2w+4+13w+1

Now, solving

= (2w+ 13w) + ( 4+ 1)

= 15 w+ 5

Using Distributive Property

a x ( b+ c) = (a x b) + (a x c)

= 15 w+ 5

= 5 x 3w + 5

=5 ( 3w+ 1)

Hence, the expression is 5 (3w+1 ).

Answer:

Transversal

Parallel Lines

Vertical Angles

Step-by-step explanation:To help you remember: the angle pairs are on Alternate sides of the Transversal, and they are on the Exterior of the two crossed lines.

Parallel Lines

When the two lines being crossed are Parallel Lines the Alternate Exterior Angles are equal. When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Exterior Angles: a and h.

Answer:

(Sorry this is a late response) 15.38=101.508 or 101.5

Step-by-step explanation:

You would divide 3 and 5 or 5 and 3 because 3 and 5 equals the fraction 3/5. The dividend is 3 and the 5 is the divisor. The quotient of this is 0.6. So the next step would be to add the 6 from 6 3/5 so this is the whole number so add it in front of 0.6 so it would turn into 6.6. The last step is to multiply the weight of the orange by the mg of vitamin C/oz that is 15.38 so multiply 6.6 by 15.38 this would equal 101.508 so you would just round this to a better answer and that would make it 101.5.

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared.  Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally.  This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered.  Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you.

Answer:

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Shape: Nonagon[/tex]

Required

Angles of rotation that would not map the shape on itself

Side of a nonagon is:

[tex]Sides = 9[/tex]

and a complete rotation is:

[tex]Complete\ Rotation = 360\°[/tex]

To start with, we calculate a possible angle of each rotation:

This is calculated by dividing the complete rotation by number of sides

[tex]Each\ Rotation = \frac{360}{9}[/tex]

[tex]Each\ Rotation = 40[/tex]

The question lacks option; so, it's difficult to give a specific answer.

However, I'll give a generalized answer

For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)

i.e.

[tex]Possible\ Angles = 40,80,120,160,200,240,280,320,360......[/tex]

Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.

The angles of rotation that would not map the figure onto itself will not be the multiple of 40 and this can be determined by evaluating the possible angle of each rotation.

Given :

To determine angels of rotation that would not map the figure onto itself, first, evaluate the possible angle of each rotation.

To determine the possible angle of each rotation the following calculation can be used:

The possible angle of each rotation is the ratio of the complete rotation to the number of sides.

[tex]\rm Each \;Rotation = \dfrac{360^\circ}{9}[/tex]

Each Rotation = [tex]40^\circ[/tex]

So, the angles of rotation that would not map the figure onto itself will not be the multiple of 40.
