A box 2 m by 4 m by 8 m is filled with cubes of volume 8 cm³. If these
cubes were lined up, how long a line would that be?

Answers

The total line length of cubes lined up would be approximately 1.6 x 10^7 cm.

To find the total line length of cubes lined up, we need to find the total number of cubes in the box and then multiply it by the side length of a cube.

We can find the total number of cubes in the box by dividing the volume of the box by the volume of a cube:

Volume of the box = 2 m * 4 m * 8 m = 64 m³

Volume of a cube = 8 cm³ = 8 x 10^-6 m³ (converting the cm³ to m³)

Number of cubes = 64 m³ / 8 x 10^-6 m³ = 8 x 10^6

Then we can multiply the total number of cubes with the side length of a cube to find the total line length of cubes lined up :

Therefore, Line Length = 8 x 10^6 * 8 cm

= 6.4 x 10^7 cm

= 1.6 x 10^7 cm.

Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?

39
40
73
91

Answers

B. 40

As we know Sid has 26 Caps

we also know that 26 is 65% of total

so let total caps = x

to calculate x

we know that percent = (Values*100)/total Values.......... i

and here Value = 26 caps

percentage = 65

So we have

65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i

65x= 2600x = 2600/65x=40 caps

Hence Answer is 40

Ava bought snacks for her team's practice. She bought a bag of oranges for $2.71 and a 4-pack of juice bottles. The total cost before tax was $6.75. Write and solve an equation which can be used to determine jj, how much each bottle of juice cost.

Answers

Answer: Let j be the cost of each juice bottle.

The total cost of the juice bottles is 4j. The total cost of the oranges and juice bottles is $6.75.

Thus, the equation that represents the given information is: 4j + $2.71 = $6.75. Subtract $2.71 from both sides to get: 4j = $4.04. Divide both sides by 4 to get: j = $1.01.

Therefore, each juice bottle costs $1.01.

Step-by-step explanation:

Total cost = cost of a bag of oranges + cost of 4-pack juice bottles

$6.75=  $2.71 + (4 x jj)

$6.75 = $2.71 + 4jj

take similar terms: $6.75 - $2.71 = 4jj

Add similar terms: $4.04 = 4jj

Divide both sides of the equation by 4: jj =  $4.04 / 4=

jj = $1.01

Describe the pros and the cons of using the standard form of a line to graph an equation.

Answers

Answer:

The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.

Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.

One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.
