REASONING Tell whether the rates are equivalent.
75 pounds per 1.5 years
38.4 ounces per 0.75 year
Answer:
No, either convert pound to ounces or the other way around.
Step-by-step explanation:
Use 1 lb= 16 oz so 75 lb=16 x 75 =1200 oz ---> 1200 ounces per 1.5 years..
---> 1200 oz/1.5 years (1)
The second equation is 38.4 ounces per 0.75 years , will be the same as 76.8 ounces per 1.5 years.---->76.8 oz / 1.5 years (2)
So compare (1) and (2) are not equivalent....
The rates are not equivalent to each other..
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
Use 1 lb= 16 oz
Thus 75 lb=16 x 75 =1200 oz
Means 1200 ounces per 1.5 years..
Now 1200 oz/1.5 years ----- (1)
The second equation is 38.4 ounces per 0.75 years which will be the same as 76.8 ounces per 1.5 years.
76.8 oz / 1.5 years ----- (2)
So compare (1) and (2) are not equivalent to each other.

b) a+r=28 ---(1)
a+2r=44 ---(2)
c) a+r=28
a=28-r ---(3)
sub (3) into (2), 28-r+2r=44
r=16
sub r=16 into (3), a=28-16

Based on your calculations in part a, did Kelvin ski twice as long without falling as anyone else in the family?
Answer:
Yes, Kevin skied twice as long as Lori without falling.
Step-by-step explanation:
Kevin's time was 223 sec and Lori's was 110 sec.
110 x 110 = 220
Since Lori's time was 110 seconds and twice that is less than Kevin's, which was 223.
Thus we have our answer:
Yes, Kevin skied twice as long as Lori did without falling.

Answer:
Y = [-6 6 6 -6]
Step-by-step explanation:
From the given matrices
If X - 2Y = Z
b - 2c = a ... 1
a -2d = c ...2
4+2a = 16.... 3
a + 2b = b .... 4
From3 ;
2a = 16-4
2a = 12
a = 6
From 4;
a + 2b - b = 0
a+b = 0
a = -b
6 = -b
b = -6
From1;
b - 2c = a
-6 - 2c = 6
-2c = 12
c = -6
also
a - 2d = c
6-2d = -6
-2d = -6-6
-2d = -12
d = 6
Hence the matrices Y = [-6 6 6 -6]

Two numbers have a sum of 7. When the smaller number is subtracted from twice the larger number, the result is 20. Which is the following is the larger number.
11
9
15
12
Which is it?
Answer:
9
Step-by-step explanation:
according to the condition it is possible to make up a system of two equations (if to suppose 'l' - the larger number and the 's' - is the smaller one):
1. 'two numbers have a sum of 7' means s+l=7;
2. 'When the smaller number is subtracted from twice the larger number, the result is 20' means 2*l-s=20.
3. the system of two equations is:
[tex]\left \{ {{s+l=7} \atop {2l-s=20}} \right. \ => \left \{ {{s=-2} \atop {l=9}} \right.[/tex]
4. the larger number is 9.
The larger number would be as follows:
[tex]9[/tex]
What are numbers?Let the two numbers (larger and smaller) be [tex]= x ; y[/tex] respectively.
[tex]x + y = 7[/tex]
So, [tex]y = 7 - x[/tex]
Given that,
The Smaller number subtracted from twice large number gives 20. Thus,
[tex]2x - y = 20[/tex]
Putting the value of [tex]y, 2x - (7 - x) = 20[/tex]
[tex]2x - 7 + x = 20[/tex]
[tex]3x - 7 = 20[/tex]
[tex]3x = 27[/tex]
[tex]x = 27 / 3[/tex]
∵ [tex]x = 9[/tex] [The larger Number]
The smaller number [tex]'y' = 7 - 9 = -2[/tex]

2. A spy uses a telescope to track a rocket launched vertically from a launch pad 6 km away. The rocket travels upwards at a velocity of 21.6 km per minute. Find the rate of change of the distance between the spy and the rocket when the rocket is 8 km in the air. Answer: 17.28 km/mim
NEED HELP ASAP
Answer:
The rate of change in distance between the spy and the rocket is 10.8 km/min,
or about 180 m/sec.
Step-by-step explanation:
At "Time=0" the rocket is 6km from the spy.
The rocket travels vertically 8km in about 0.37 minutes, calculated by 8km÷21.6km/min.
At that point, the rocket is 10 km from the spy., calculated by 6²+8²=10²
The difference is 4 kiilometers over 0.37minutes, about 22.2 seconds
Divide Distance by Time to get Rate:
4km/0.37min = 10.8 km/min
That is about 180 meters per second.

You want to find out how sleep deprivation affects motor performance. To study this, you have sleep-deprived subjects (such as parents of newborn babies or night-shift workers) record the number of minutes they sleep each night and take a series of motor performance assessments, with 1 minute being the smallest unit on the scale. Suppose the first subject sleeps 250 minutes. Determine the real limits of 250.
Answer:
the real limits are;
Lower Real Limits = 249.5
Upper Real Limits = 250.5
Step-by-step explanation:
Given the data in the question;
1 minute being the smallest unit on the scale
so we say; 1/2 which 0.5 minutes which we will use to calculate pur real limits time;
given that; the first subject sleeps 250 minutes
so
Lower Real Limits will be;
Lower Real Limits will = 250 - 0.5 = 249.5
Also our Upper Real Limits will be;
Upper Real Limits = 250 + 0.5 = 250.5
Therefore; the real limits are;
Lower Real Limits = 249.5
Upper Real Limits = 250.5
Decrease 60kg by 40%
Answer:
36 KG
Step-by-step explanation:
This is how I did it:
60 x 0.6 = 36
1 = 100%
0.4 = 40%
but you have to decrease so
100% - 40% = 60%
60% = 0.6
