Una caixa plena de raïm pesa 21 quilos. Si el raïm d’allà pesa 1.9 quilos, quant pesa la caixa buida
Answer:
7.6 quilograms
Step-by-step explanation:
Pas 1
Convertim el pes de la caixa completa de raïm a quilograms
1 lliura = 0.454 quilograms
21 lliures = x
Creu Multiplicar
x = 21 × 0.454 quilograms
x = 9.52544 quilograms
Aproximadament 9.5 quilograms
Ens van dir que el raïm d’allà pesava 1.9 quilos,
Per tant, el pes de la caixa buida és
= 9.5 - 1.9
= 7.6 quilograms
El pes de la caixa buida és de 7.6 quilograms

Driving at constant speed, Rusty drove 600 miles in 10 hours.
How many miles would he drive in 15 hours?
Answer:
hello, okay so im in 6th so this is easy. so
Step-by-step explanation:
figure out what 1 mile is. 1 mile would be 600 divided by 10, which is 60. so 60*15 would be 900. so he would drive 900 miles in 15 hours. :);

Do not use decimals in your answer.
Answer:
42 - 14x = 9
Step-by-step explanation:
Given
2 - [tex]\frac{2}{3}[/tex] x = [tex]\frac{3}{7}[/tex]
Multiply through by 21 ( the LCM of 3 and 7 ) to clear the fractions
42 - 14x = 9 ← with no fractions
Answer:
14x - 33 = 0
Step-by-step explanation:
2 - (2/3) x = 3/7
6 - 2x = 9/7 (multiply 3)
42 - 14x = 9 (multiply 7)
14x - 33 = 0

Answer:
We conclude that the range of the function will be:
R = {5, 17, 29}
Step-by-step explanation:
Given
Given the function
f(x) = 6x-1
Given the domain
D = {0, 3, 5}
To Determine:
The range R = ?
We know that range of the function consists of all the y-values for the x-values in the domain of the function.
so substituting the values of x = 0, 3, and 5 in the function to determine the corresponding y-values.
Plug in x = 0
y = 6x-1
y = 6(0) - 1 = 6-1 = 5
Plug in x = 3
y = 6x-1
y = 6(3) - 1 = 18-1 = 17
Plug in x = 5
y = 6x-1
y = 6(5) - 1 = 30-1 = 29
Now, combine all the determined y-values which are 5, 17, and 29.
Therefore, we conclude that the range of the function will be:
R = {5, 17, 29}

the image of point A under a 90° rotation about the origin is A'(10, -4). What are the coordinates of point A?
Given:
The image of point A under a 90° rotation about the origin is A'(10, -4).
To find:
The coordinates of point A.
Solution:
90° rotation about the origin means the figure is rotated 90° counterclockwise about the origin and the rule of rotation is
[tex](x,y)\to (-y,x)[/tex]
Let the coordinates of A are (a,b).
[tex]A(a,b)\to A'(-b,a)[/tex]
The image of point A under a 90° rotation about the origin is A'(10, -4).
[tex]A'(-b,a)=A'(10,-4)[/tex]
On comparing both sides, we get
[tex]-b=10\Rightarrow b=-10[/tex]
[tex]a=-4[/tex]
Therefore, the coordinates of point A are (-4,-10).

Zara has forgotten her 4-digit PIN code.
She knows the first digit is a factor of 10 and the 4 digits make a number divisible by 2.
How many different sets of 4 digits could it be?
Answer:
1500
Step-by-step explanation:
we can write the 4-digit PIN as ABCD
A = factor of 10 so,
A = 1, 2 ,5 (3 possible number or we can write n(A) = 3
B and C are number from 0 - 9 so each have 10 possible number n(B) = 10 and n(C) = 10
D makes the whole number cannbe divide by 2. it means that D must even number 2,4,6,8 or 0. so there are 5 possible number n(D) = 5
so to find how many different sets we just multiply all possible number
n(A) x n(B) x n(C) x n(D)
3 x 10 x 10 x 5 = 1500 different sets

True.
Step-by-step explanation: Because -9 is less than -6 because -6 is a bigger number than -9.
Graph two more functions in the same family
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the slope-intercept of the line equation is
[tex]y = mx + b[/tex]
where m is the slope and b is the y-intercept
Please note that a linear equation contains no powers of x besides.
For example, the equation of the form
y = 2x+3
has the slope m = 2 and y-intercept b = 3
The graph is shown below.
Let us graph two more functions of the same family by changing the parameter of y-intercept b.
Graphing y = 2x+5
y = 2x + 5
has same slope m = 2. But, the y-intercept b = 5
The graph of y = 2x+5 is attached below.
Graphing y = 2x+7
y = 2x + 7
has same slope m = 2. But, the y-intercept b = 7
The graph of y = 2x+7 is attached below.
Thus, we would have the following graphs of the family of linear functions.
y = 2x+3y = 2x + 5y = 2x + 7Please notice that all the functions have the same slope m = 2. Thus, all the lines would be parallel.
Thus, from the graph, it is clear that:
The red line represents the function y = 2x+3 with the y-intercept (0, 3)The blue line represents the function y = 2x+5 with the y-intercept (0, 5)The green line represents the function y = 2x+7 with the y-intercept (0, 7)The graph is attached below.

Step-by-step explanation:
A salesman gets a basic wage of £160 per week plus a commision of 30%
of the sales he makes that week.
In one week his total wage was £640
Work out the value of the sales he made that week.
Please help, I really need this answered. Will award brainliest.
Step-by-step explanation:
total profit or income =640+160=800the # means that the answer is ready in my openion i think
Step-by-step explanation:
30÷100×640=192
total income =160+192
=352
weekly sales=?(x)
wage=640
so...
x×0.3+160=640
0.3x=640-160
0.3x=480
x=480÷0.3
x=1600
the weekly sales is 1600

Mrs. Smith has a total of 27 kids in her class. There are 6 more boys than there are girls. Write a system of equations to model this.
Some Equations:
6 + x = 27
x + 6 = 27
27 - 6 = x
27 - x = 6
27 = x + 6
27 = 6 + x
There are 11 girls
A system of equations to model this statement is x + (x + 6) = 27.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, There are 6 more boys than there are girls.
Assuming no. of girls to be x, therefore no. of boys is (x + 6).
Mrs. Smith has a total of 26 kids in her class.
∴ x + (x + 6) = 27.

What is the sum of the next two numbers in the pattern 169,120,84,59,43,_,_
Answer:
64
Step-by-step explanation:
Here, we want to know the sum of the next two terms
We need to get the pattern first
The difference between the first two numbers is 49 (7^2)
next two is 36 (6^2)
next two is 25 (5^2)
next two is 16 (4^2)
next two will be 3^2 = 43-9 = 34
next will be 2^2 = 34-4 = 30
So the sum here is 30 + 34 = 64
