Calculate the force created from an object with a mass of 1250 grams and an acceleration of 3 m/s^2
Please help!! I will mark as brainliest
The force created by the object is 3.75 Newton.
Given
Mass of the object (m) = 1250 grams
Convert 1250 grams to kilograms by dividing it by 1000.
Mass (m) = 1.25 kg
Acceleration of the body (a) = 3 [tex]m/s^{2}[/tex]
From Newton's second law we know [tex]F= m *a[/tex]
By Substituting in the above equation we get
Force = 1.25 x 3
Force = 3.75 [tex]kg/m /s^{2}[/tex]
It can also be written as force = 3.75 N
Hence Force created by the body is 3.75 Newton.

Evaluate,f(-4) for f(x)=-x^2-4x+42
Please explain by step by step please!
The output value of f( -4 ) in the function f(x) = -x² - 4x + 42 is 42
What is the output value of f( -4 ) in the given function?A function is simply a relationship that maps one input to one output. Every x-value can only have one y-value to qualify as a function.
Given the data in the question;
f( x ) = -x² - 4x + 42f( -4 ) = ?To find the output value of f( -4 ), replace all the occurrence of x with -4 in the function and simplify.
f( x ) = -x² - 4x + 42
f( -4 ) = -(-4)² - 4(-4) + 42
f( -4 ) = -( 16 ) + 16 + 42
f( -4 ) = -16 + 16 + 42
f( -4 ) = 42
Therefore, the output value of f( -4 ) is 42, this forms an ordered pair of (-4, 42).

You have $28 to go bowling. It costs $3.00 to rent a pair of bowling shoes and $3.25 per
game. At most, how many games will you be able to bowl?
Answer: 7 games
Explanation:
1. take the information and put it into a equation (being y=3.25x+3 or f(x)=3.25+3)
2. replace the x with a whole number because you can't bowl half a game.
Ex: f(3)=12.75 or f(6)=22.50
3. The highest you can go without going over your money is 7 games ($25.75) leaving you with a total of 2.25.

A) 90º clockwise
B) 90º counterclockwise
C) 180º
D) 270º clockwise
E) 270º counterclockwise
is 2 correct answers ❗️
Answer: B) 90º counterclockwise
Step-by-step explanation:
First, let us look at clockwise vs counterclockwise. Clockwise is in the direction of a clock, spinning around to the right. Counterclockwise is the opposite, spinning to the left.
A) 90º clockwise
➜ This is 90 degrees to the right.
B) 90º counterclockwise
➜ This is 90 degrees to the left
C) 180º
➜ This is directly flipped.
D) 270º clockwise
➜ This is 270 degrees to the right.
E) 270º counterclockwise
➜ This is 270 degrees to the left.
We will look at the answer options and decide which makes the most sense. This looks to be option B, 90º counterclockwise as shown in the image attached.
How to make x the subject if m=n+x/p
Variable x as the subject of the equation given is expressed as: x = p(m - n).
How to Make a Variable the Subject of the Formula?To make a variable the subject of a formula implies that we express the equation in terms of the variable. Thus, to make a variable the subject of the formula, we have to make the variable stand alone on one side of the equation.
Given the equation, m = n + x/p, make x the subject as explained below:
m = n + x/p [given]
Subtract n from both sides
m - n= n + x/p - n (subtraction property of equality)
m - n = x/p
Multiply both sides by p
p(m - n) = x/p(p) (multiplication property)
p(m - n) = x
x = p(m - n)

10. The sales tax rate in a certain state
Find the total price paid for a pair of shoes
that cost $35.
the total price paid for a pair of shoes after tax is included is $37.1.
A sales tax is a tax paid to the government for sales of certain types of goods and services.
According to the question,
Cost of the shoes = $35. (given)
Total amount/price paid = cost + tax
As the tax percentage is not given in the question, we will assume it to be 6% for example. Then,
Tax amount = 6% of $35
= 6/100*35
= $2.1
Now, total price = cost + tax
= $35+$2.1
= $37.1
Therefore, we conclude that the total price paid for a pair of shoes after tax is included is $37.1.

Jordan needs to order some new supplies for the restaurant where he works. The restaurant needs at least 730 knives. There are currently 204 knives. If each set on sale contains 10 knives, write and solve an inequality which can be used to determine xx, the number of sets of knives Jordan could buy for the restaurant to have enough knives
Answer:
53 sets
Step-by-step explanation:
730 - 204 = 526
526 / 10 = 52 r 6
therefore he'd have to buy 53 sets to have enough knives.
There are 53 number of sets of knives Jordan could buy for the restaurant to have enough knives.
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The restaurant needs at least 730 knives.
There are currently 204 knives.
And, each set on sale contains 10 knives.
Now,
By the given condition, we formulate;
⇒ 730 ≤ 204 + 10x
Solve for x as;
⇒ 730 ≤ 204 + 10x
⇒ 730 - 204 ≤ 204 + 10x - 204
⇒ 529 ≤ 10x
Divide by 10 as;
⇒ 52.9 ≤ x
After rounding, we get;
⇒ 53 ≤ x
Thus, There are 53 number of sets of knives Jordan could buy for the restaurant to have enough knives.

where X is the score on a fair, six-sided dice.
P(B or C) means "the probability of rolling an even number or a multiple of 3".
As an even number of a fair, six-sided dice can never be a multiple of 3, the two events B and C are mutually exclusive.
Calculate the probabilities for events B and C.
Event B
Rolling an even number.
[tex]\begin{aligned}\implies \text{P}(X \text{ is even})&=\text{P}(2 \text{ or }4\text{ or }6)\\\\&=\text{P}(X=2)+\text{P}(X=4)+\text{P}(X=6)\\\\& = \dfrac{1}{6}+ \dfrac{1}{6}+ \dfrac{1}{6}\\\\&=\dfrac{3}{6}\end{aligned}[/tex]

Ang has x dollars in his savings account, and Julia has y dollars in her savings account. Ang gives Julia 1/3 of the money in his savings account, which Julia deposits into her savings account. Julia then spends 1/4 of the total in her savings account. Express the amount of money Julia spent non terms of x and y.
Answer choices
1. y/4 + x/12
2. y/4 + x/3
3. y/4 + x/7
4. 3y/4 + x/4
In terms of x and y, Julia's withdrawal from her savings account was equal to y/4 + x/12.
What does algebraic expression mean?An expression obtained by performing a finite number of algebraic fundamental operations on symbols representing numbers.
What is an illustration of an algebraic expression?Algebraic expressions have at least one variable and one operation (addition, subtraction, multiplication, division). 2(x + 8y) is an example of an algebraic expression.Both Ang and Julia have savings balances of x and y dollars, respectively.
Ang = x dollars
Julia = y dollars
Ang offers Julia a third of his savings, which she then transfers to her own savings account.
Amount in Julia's account = (1/3)x + y
Julia then spends a quarter of the total into her savings account.
Amount of money Julia spent = 1/4 × [(1/3)x + y]
= (1/12)x + (1/4)y
= y/4 + x/12
Therefore, in terms of x and y, the amount Julia spent from her savings account is y/4 + x/12.

How many tiles measuring 20cm by 50cm are needed to completely cover a wall 4m by 8m?
The number of tiles measuring 20cm by 50cm that are needed to completely cover a wall 4m by 8m is :320.
Number of tiles neededFirst step is to convert the Meters to Centimeters
4m = 400cm
8m = 800 cm
Hence,
4m by 8m = 400 cm × 800 cm
4m by 8m = 320,000 cm²
Second step is to determine the how many tiles are needed
Number of needed tiles = 320,000 cm² / ( 20 cm × 50 cm)
Number of needed tiles = 320,000 cm² /1,000 cm²
Number of needed tiles = 320
Therefore 320 tiles are needed.

Find the approximate side length of a square game board with an area of 160
in2.
The approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.
As given in the question,
Area of the square game board is equal to 160in².
Let 'x' inches be the side length of the square game board.
Area of the square game board = (side length)²
⇒ 160 = ( x )²
Take square root both the sides we get,
x = √160
⇒ x = 12.649 inches
⇒ x = 12.6 inches( approximately)
Therefore, the approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.
