Answer:
a. Maurice walked farther.
b. 0.62 m
Step-by-step explanation:
Maurice
4.1 × 1.8 = 7.38 miles
Junnie
2.5 × 3.2 = 8 miles
This shows that Junnie walked more than Maurice.
8 - 7.38 = 0.62
Junnie walked 0.62 m more than Maurice

I NEED HELP Are the two functions inverses? f ( x ) = − 8 x + 5 g ( x ) = − 1 8 x + 5 8 Group of answer choices Yes No
Answer: No
Step-by-step explanation:
To know if the functions are inverses of each other, it is easiest to just find the inverse of one of the functions. To find the inverse, you want to replace y with x and x with y and solve for y.
y=-8x+5 [switch x with y and y with x]
x=-8y+5 [subtract both sides by 5]
x-5=-8y [divide both sides by -8]
y=(x-5)/-8
f⁻¹(x)=(x-5)/-8
Since we know that the inverse doesn't match g(x), we know that these functions are not inverses of each other.

A 2000 kilogram sports car accelerates at a ratr of 30 meters per second squared. The velocity of the car is v=at where a is acceleration in meters per second squaref and t is tome in seconds. The kinetic energy of the car is KE = 1/2 mv^2
Answer:
KE = 900,000t²
Step-by-step explanation:
The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;
m is the mass of the sport car = 2000kg
v is the velocity of the car
Since v = at
v = 30t
Substituting the given values into the KE formula;
KE 1/2 * 2000 * (30t)²
KE = 1000*900t²
KE = 900,000t² Joules where t is the time measured in seconds
Answer:
KE = 900,000t²

Determine the rate of change for 3/2x -5/4y = 15
Answer:
-6/5
Step-by-step explanation:
3/2x - 5/4y = 15
-5/4y = -3/2x + 15
multiply each side by (-4/5)
(-4/5)(-5/4y) = (-4/5)(-3/2x + 15)
y = -6/5x - 12
rate of change: -6/5
Lee spent $29 to purchase a combination of drinks, sandwiches, and chips for himself and his friends. A drink costs $1.50, a sandwich costs $5, and chips cost $1.25. Identify the linear equation that represents this situation.
Answer:
1.5d+5s+1.25c=29
Step-by-step explanation:
let d be the number of drinks, s be the number of sandwich, and c be the number of chips Lee purchased.
1.5×d and 5×s and 1.25×c must total 29, or
1.5d+5s+1.25c=29.
A research company wants to test the claim that a new multi vitamin helps improve short term memory state the objective of the experiment suggest a population determine the experimental and control groups and describe a simple procedure
Answer:
To test the effects of the multi-vitamin, we must test it on people with short-term memory loss. So the population should be people with short-term memory loss. The independent variable is the multi-vitamin and the dependent variable is the short term memory state of the people being tested. A control group can consist of people with short-term memory loss NOT being treated by the multi-vitamin.

Write 6.93 repeating a mixed number in simplest form.
6.93 =?
Answer:
[tex]6\frac{93}{100} = \frac{693}{100}[/tex]
Step-by-step explanation:
Turn 6.93 into a fraction: [tex]6\frac{93}{100}[/tex] To turn into a mixed number, first multiply 6 and 100, then add 93. Put 693 over 100: [tex]\frac{693}{100}[/tex]I hope this helps!
Answer: [tex]6 \frac{31}{33}[/tex]
This is a mixed number where the whole part is 6, and the fractional part is 31/33.
=============================================
Explanation:
The 93 repeats forever, so we can say
x = 6.939393...
100x = 693.939393....
Subtracting the left hand sides leads to 100x-x = 99x
Subtracting the right hand sides leads to 693.939393.... - 6.939393... = 687
Notice how the decimal terms cancel out when we subtract.
We're left with 99x = 687 which solves to x = 687/99
This reduces to 229/33 when you divide both parts by 3.
The last step is to convert to a mixed number
The answer will be in the form [tex]6 \frac{x}{33}[/tex] where 6 is the whole part and x/33 is the fractional part. We know the whole part is 6 from the 6 in the original number given.
229/33 = 6.939393... helps confirm we're on the right track so far
this is another way of saying 229/33 = 6 remainder x, where x is the unknown remainder and the numerator we're after for the fraction x/33.
To get the remainder, we just compute 229-6*33 to get 31
This means 31/33 = 0.93939393...
and that [tex]6 \frac{31}{33} = 6.\overline{93} = 6.93939393...[/tex]
I’m a constant function. There are two possible ways to write me; one way being slope-intercept form and the other being constant form
(I don’t really understand what this question is asking)
Answer:
constant function has the same output no matter what are the inputs and it is written in the form : y=b where b is a constant that does not change. the slope of this function always equal to zero.
slope intercept form : y=mx+b ( where m=0)
constant form : y=b ( y equal a constant that does not change)
Please HELP ASAPPPP uts not -3!!!
Answer:
x= 11
Step-by-step explanation:
(7x -1)° + (9x +5)°= 180° (adj. ∠s on a str. line)
7x -1 +9x +5= 180
16x +4= 180 (simplify)
16x= 180 -4 (-4 on both sides)
16x= 176 (simplify)
x= 176 ÷16
x= 11
The sum of the angles on a straight line is 180°

1/2(-2x - 12) > 7(3 - 4x)
The solution is____
Answer:
x > 1
interval (1,∞)
Step-by-step explanation:
1/2(-2x - 12) > 7(3 - 4x)
-x - 6 > 21 - 28x
-x + 28x > 21 + 6
27 x > 27
x > 27 / 27
x > 1
interval (1,∞)
-x - 6 > 21 - 28x if x = 2
-2 - 6 > 21 -28(2)
-8 > 21 - 56
- 8 > - 35
Each school day, Aidon wolks 11 blocks to school after school, he wolks 4 blocks to the library
and 12 blocks home. How many blocks does Aidon wolk in a week? *
e
Answer:
189
Step-by-step explanation:
Aidon walked 11 blocks to begin with than he walks 4 blocks to the library and 12 blocks home. This mean we add 11+4+12=27 and a week has 7 days which means we need to multiply that by 7 which gives us the product of 189.

on a piece of paper, graph y<-3/4x+2. Then determine which answer choice matches the graph you drew.
Answer:
D. Graph D
Step-by-step explanation:
The "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.
Only one graph has a dashed line with shading below: Graph D.
