Answer:
The acceleration of the car will be 400 m/s².
Step-by-step explanation:
The acceleration of the car can be found using Newton second law:
[tex] F = ma [/tex]
Where:
F: is the net force = 200 N
m: is the mass = 500 g
a: is the acceleration =?
Then, the acceleration will be:
[tex] a = \frac{F}{m} = \frac{200 N}{500 g*\frac{1 kg}{1000 g}} = 400 m/s^{2} [/tex]
Therefore, the acceleration of the car will be 400 m/s².

Answer:
Step-by-step explanation:
First, change the fractions into decimals, then use the knowledge of the number line system to know which is greater or smaller than who.
-7/5 -1.4
3/4 0.75
so the numbers are -1.4, 16, -1, 3.2, -6.5, 0, 0.75
from greatest to least:

Solve the following system of equations:
x − 2y = 14
x + 3y = 9
Answer:
(12, - 1)
Step-by-step explanation:
x - 2y = 14 ......... (1)
x + 3y = 9 ......... (2)
(2) - (1)
(x - x) + (3y - ( - 2y)) = 9 - 14
5y = - 5 ⇒ y = - 1
x + 3( - 1) = 9 ⇒ x = 12

Square root of 13
Square root of 85
14
13
Answer:
Square root of 85
Step-by-step explanation:
We can envision the segment AB as the hypotenuse of a right triangle with a height of 6 units and a length of 7 units. We can use the Pythagorean Theorem to solve for the length of segment AB which is similar to distance formula.
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
c = Square root of 85.

A system of two linear equations with two variables is
shown below.
2x + y = 7
3x - 4y = 5
Which answer is the solution to the system of linear
equations?
Answer:
:/
Step-by-step explanation:
Answer:
x = 3, y = 1
Step-by-step explanation:
Given the 2 equations
2x + y = 7 → (1)
3x - 4y = 5 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the y- term
8x + 4y = 28 → (3)
Add (2) and (3) term by term to eliminate y
11x = 33 ( divide both sides by 11 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 7
6 + y = 7 ( subtract 6 from both sides )
y = 1
solution is x = 3 and y = 1

Answer:
False
Step-by-step explanation:
$650,000 was stolen from 1st Trust American Bank during a heist. The bank robbers got away clean and sped away traveling at a constant rate of 70 miles per hour. What the robbers did not realize is that one of the bank bags had a GPS tracking device inside of it. Once the police locked on to the signal of the tracking device they took off after the robbers traveling at a constant rate of 90 miles per hour. If the robbers already had a 30 mile head start, how long will it take the police to pass them and force them off the road to be arrested?
Answer:
The time taken before the police force the robbers off the road is 1.5 hours
Step-by-step explanation:
The speed with which the robbers were travelling = 70 miles per hour
The speed with which the police went after the robbers = 90 miles per hour
The distance with which the robbers were in front of the police before the police came after them = miles
Let t represent the time in hours the police force the robbers off the road, we have;
30 + 70 × t = 90 × t
30 = 90 × t - 70 × t = (90 - 70) × t = 20 × t
30 = 20 × t
20 × t = 30
t = 30/20 = 1.5
t = 1.5 hours
The time taken before the police force the robbers off the road = t = 1.5 hours
Answer:
The time taken before the police force the robbers off the road is 1.5 hours

Jeff is purchasing a car for $29,175 that will depreciate in value 7.5% each year.
Write a function to model the value P of the carafter t years,
If he decides to sell the car after 6 years, what will be the value of his car? Express your answer as a decimal rounded to the nearest hundredth.
Answer:
p= 18,275
Step-by-step explanation:
The function would be p=29,175(-0.925)^t. You would then substitute t for 6 and solve from there to get p=18,275.

Here's a graph of a linear function.
Write the
equation that describes that function.
Express it in slope-intercept form.
Answer:
y = 1/2x + 3Step-by-step explanation:
As per graph, using the points (-6, 0) and (0, 3) we determine that:
the y-intercept is 3 and the slope is m = (3-0)/(0 - (-6)) = /3/6 = 1/2So the equation is:
y = mx + by = 1/2x + 3The equivalent of (-8)-4.(-8)2
The equivalent value of the expression (-8)-4.(-8)² is 768
what is expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.
Given:
(-8)-4.(-8)²
Using properties of integers
(-8-4)*(-8* -8)
=(-12) * (-64)
= 768
Hence, the equivalent value is 768.

A nest of ants has been growing exponentially in such a way that it's population,P, as a function increasing on average more or less than 1600 ants per week? Enter the value per week to the nearest tenth.
Not sure question is complete, assumptions however
Answer and explanation:
Given the above, the function of the population of the ants can be modelled thus:
P(x)= 1600x
Where x is the number of weeks and assuming exponential growth 1600 is constant for each week
Assuming average number of ants in week 1,2,3 and 4 are given by 1545,1520,1620 and 1630 respectively, then we would round these numbers to the nearest tenth to get 1500, 1500, 1600 and 1600 respectively. In this case the function above wouldn't apply, as growth values vary for each week and would have to be added without using the function.
On one hand, the function above could be used as an estimate given that 1600 is the average growth of the ants per week hence a reasonable estimate of total ants in x weeks can be made using the function.

Last year, the school library had a total of x books. Over the summer, the library acquired another 40 books and now has a total of 1,795 books. Which equation could be used to find x, the number of books the library had last year?
Answer:
1794-40=x?
Step-by-step explanation:
this is genuine answer but a little bit unsure
Last year = x books
This year = x + 40 books
The needed equation is x + 40 = 1,795.

fruit in the bowl are apples?
A. 0.06%
B. 40%
C. 6%
D. 0.4%
Answer:
40%.
