A box has a total surface area of $100.$ The length of the box is equal to twice its width, as well as equal to $3$ less than it
CaHeK987 [17]

Answer:

Formula:  width x depth x height

Step-by-step explanation:

times 100 and 3. As we know that the formula for a box is  width x depth x height.

We need to measure the box from all side so 4 sides. so times the 2 number by 2 cause there is 4 sides each.

Hope this helps

Pls help! I'm confused. Can you explain this if you can.
alexdok [17]

Answer:

From a <u>table</u>, for an ordered pair (0, y), <em>y</em> will not be <u>zero</u>. From a <u>graph</u>, the y-intercept will not be <u>zero</u>.  From an equation, it will have the form, y = mx + b where b is <u>≠ 0</u>.

Step-by-step explanation:

  • From a <u>table</u>, for an ordered pair (0, y), <em>y</em> will not be <u>zero</u>. If there is not a constant rate of change in the data displayed in a table, then the table represents a nonlinear nonproportional relationship.
  • From a <u>graph</u>, the y-intercept will not be <u>zero</u>. This means that it doesn't contain or go through the origin.  
  • From an equation, it will have the form, y = mx + b where b is <u>≠ 0.</u> (not equal to zero). If an equation is not a linear equation, it represents a nonproportional relationship. A <u>linear equation</u> of the form y = mx + b may represent either a <em>proportional</em> (b = 0) or <em>nonproportional</em> (b ≠ 0) relationship.  Therefore, when b ≠ 0, the relationship between <em>x</em> and <em>y</em> is <u>nonproportional</u>.

trevon spent 8 hours and 15 minutes at an amusement park yesterday he spent 75% of the time at the park about how much time did
Lostsunrise [7]
Convert 8 hours and 15 minutes into minutes-   8 x 60=480 480+15=495
100%-75%=25%
25%=0.25
0.25 x 495  = 123.75 minutes or 2 hour and 3.75 minutes

Hope this helps!!

Use the figure below to find the missing sides and angles.
Sunny_sXe [5.5K]

Answer:

AC = BC = 5

AB = 5√2

∠A = ∠B = 45

∠A = 90

Step-by-step explanation:

AC = 5 ( Reason : 5 squares are present in between A and C )

Similarly,

BC = 5

<u>By Pythagoras theorem</u>,

(AB)² = (AC)² + (BC)²

        = 5² + 5²

        = 2 * 5²

(AB)² = 2 * 5²

AB = 5√2

Since, sides AC and BC are equal,

∠A = ∠B = 45

Since, AC is perpendicular to BC,

∠A = 90
