Answer:

1. Andrew- 24

  Brandon-  6      

  Carlo- 10

  oh god idk

2. he would have to get 100% because 90+90=180 and 180-80-100 and so 100+80=180 and 180/2=90 so 100%

3. 92.6 because 90+98+96+94+85=463 and 463/5=92.6 and 463+92.6=555.6 and 555.6/6 is 92.6 which is ultimately 92

4. idk understand stem and leaf plots but this is how you find a median

The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Answer:

from that passage AB+BD=AD ; -4x+50+2x+4=2x+46 so -2x+54=2x+46 ; x=2.

AC=AB+BC ; AB=-4x+50=-4(2)+50=42

the total lengths is AD=2x+46=50

Therefore AC is more than 42 and less than 50 ; you can answer b,c,g

The table below lists the masses and volumes of several pieces of the same type of metal. There is a proportional relationship b
Murrr4er [49]
Given the table below which lists the masses and volumes of several pieces of the same type of metal.<span>

From the table the ratio of the mass to the volume of the metal of mass 34.932 is 34.932 / 4.1 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 47.712 is 47.712 / 5.6 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 61.344 is 61.344 / 7.2 = 8.52
</span><span><span>the ratio of the mass to the volume of the metal of mass 99.684 is 99.684 / 11.7 = 8.52

</span>MASS (grams)            VOLUME (cubic cm.)
34.932                               4.1
47.712                              5.6
61.344                              7.2
99.684                              11.7</span>

Since the ratio of the various masses to the volume of the metals is the same, so there is a relationship between the mass and the volume of the piece of metal.

If the volume of a piece of metal is 15.3 cubic cm, then the mass of the metal is given by 15.3 * 8.52 = 130.356 grams.

P is a rectangle with a length 40 cm and width x cm
TiliK225 [7]
The first thing we must do for this case is to look for the area of each rectangle.
 We have then:
 A1 = (40) * (x)
 A2 = (1.25 * 40) * (y)
 Then, we have the following relationship between areas:
 "the area of Q is 10% less than the area of p"
 A2 = 0.9 * A1
 Substituting values we have:
 (1.25 * 40) * (y) = 0.9 * ((40) * (x))
 We rewrite:
 50y = 36x
 The relationship x: y is:
 x / y = (50) / (36)
 Simplifying:
 x / y = (25) / (18)
 Answer:
 
the ratio of x:y is:
 
25:18
