Answer: (d)- 1.76 kg
Step-by-step explanation:
Given
The first laptop mass was 11 kg
The rate of mass decreases by 4.7% per year
In 1982, it was
[tex]\Rightarrow 11-11\times 4.7\%=11-11\times 0.047\\\Rightarrow 11(1-0.047)\ kg[/tex]
In 1983, it was
[tex]\Rightarrow 11(1-0.047)-11(1-0.047)\times 0.047=11(1-0.047)^2[/tex]
In 2019 i.e. after 38 years, it is
[tex]\Rightarrow 11(1-0.047)^38=11\times 0.953^{38}=1.76\ kg[/tex]

Answer:
[tex]y\leq 4[/tex]
Step-by-step explanation:
The range is about the y values, and by looking at this parabola we can see that the maximum value is a 4. So the range would be the maximum and below (where the parabola extends to). So the values in the range would be equal to 4 and less than since the parabola is negative.

Divide the figure into 3 shapes: 2 rectangles and 1 square
Area of rectangle 1: L * W
L = 5, W = 2
2 * 5 = 10 m^2
Area of rectangle 2: L * W
L = 6 + 2 , W = 3
8 * 3 = 24 m^2
Area of square: s^2
2^2 = 4 m^2
Add all them together
10 + 24 + 4 = 38 m^2
Step-by-step explanation:
Area of the top Horizontal Rectangle =
Length x Width

Area of the bottom vertical rectangle =

The sum of two numbers is 120. The greater number is 3 times the
smaller. Find these numbers.
Answer:
x= 30, y= 90
Step-by-step explanation:
Let the smaller number be x and the greater number be y.
Given that the sum of the 2 numbers is 120,
x +y= 120 -----(1)
The greater number is 3 times the smaller number:
y= 3x -----(2)
Substitute (2) into (1):
x +3x= 120
Simplify:
4x= 120
x= 120 ÷4 (÷4 on both sides)
x= 30
Substitute x= 30 into (2):
y= 3(30)
y= 90
Answer:
Solution :-Let the first number be x
Then the second number will be 3 × x = 3x
According to the question
3x + x = 120
4x = 120
Taking 4 to RHS
x = 120/4
x = 30
Number are
x = 30
3x = 3(30) = 90

the height of the rectangular box is 4 times its width, and its length is 2 in more than its width. the volume of the box is 60in^3
Step-by-step explanation:
height= 4b
length = 2 + b
volume = 60in³
or, l ×b × h = 60in³
or, (2+b) × b × 4b = 60in³
or, 4b²(2+b) = 60in³
or, 8b² + 4b³ = 60
or, 2b² + b³ = 15
or, b³ + 2b² -15= 0
b= 1.95
l= 2+1.95=3.95
h= 4×1.95 = 7.8

Tell whether the given value is a solution of the inequality.
5x - 17 > 62; x = 13
Answer:
the given value x=13 is not a solution of the inequality
Step-by-step explanation:
we first need to solve this inequality (can treat the inequality like a normal equation to solve it)
5x-17 > 62
5x > 79
x>(79/5)
keep in mind that (79/5)=15.8
so x needs to be bigger than 15.8 in order to satisfy this inequality.
since 13<15.8 when x=13 it does not satisfy the inequality
therefore the given value x=13 is not a solution of the inequality

whats the answer for y=-[tex]\frac{2}{3}[/tex]x+4 and y=[tex]\frac{1}{3}[/tex]x-2
Step-by-step explanation:
[tex]y = -\frac{2}{3}x + 4[/tex]
[tex]y = \frac{1}{3}x - 2[/tex]
Since both equations are set equal to [tex]y[/tex], we can take the right-hand side of each equation and set them equal to each other to solve for [tex]x[/tex]:
[tex]-\frac{2}{3}x + 4 = \frac{1}{3}x - 2[/tex]
[tex]-\frac{2}{3}x - \frac{1}{3}x = -2 - 4[/tex]
[tex]-x = -6[/tex]
[tex]x = 6[/tex]
Now we can plug this value into either equation to solve for [tex]y[/tex]:
[tex]y = \frac{1}{3}x - 2[/tex]
[tex]y = \frac{1}{3}(6) - 2[/tex]
[tex]y = 2 - 2[/tex]
[tex]y = 0[/tex]
So the solution to the system of equations is [tex](6, 0)[/tex]
Write an equation of the line shown with point-slope form.
Given:
The line passes through the points (2,0) and (4,3).
To find:
The point-slope form of the given line.
Solution:
The point slop form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.
The line passes through the points (2,0) and (4,3). So, the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-0}{4-2}[/tex]
[tex]m=\dfrac{3}{2}[/tex]
The slope of the line is [tex]m=\dfrac{3}{2}[/tex] and the point is (4,3). So, the point slope form of the given graphed line is:
[tex]y-3=\dfrac{3}{2}(x-4)[/tex]
Therefore, the point slope form of the given line is [tex]y-3=\dfrac{3}{2}(x-4)[/tex].

Describe how you can find the number of solutions of two or more
equations by using the slope and the y-intercept. Use vocabulary terms in
your description.
Answer:
Suppose we have a system of two linear equations, this can be written as:
y = a*x + b
y = c*x + d
Now, we have 3 possible cases here.
The solutions of the system are the points where the graphs of the linear equations do intersect.
Then, if for example, we have two parallel lines (two parallel lines never intersect) we have no solutions.
And we know that two lines are parallel if they have the same slope and different y-intercept.
Then the system:
y = a*x + b
y = a*x + c
has no solutions.
If we have both equal lines, then the lines intersect in infinitely many points, meaning that we have infinite solutions, then the system:
y = a*x + b
y = a*x +b
has infinite solutions.
And if the lines intersect only one time we have one solution, and this happens when the slopes are different, so the system:
y = a*x + b
y = c*x + d
has only one solution.
Now, if we have more equations:
y = a*x + b
y = c*x + d
y = k*x + n
We have more equations than variables, then this system only has one solution of the 3 lines intersect at the same point, which is really rare.
One case where we have a solution here is if the 3 equations have the same y-intercept:
y = a*x + b
y = c*x + b
y = d*x + b
where the solution is the point (0, b)
Of course, there are other possible solutions, but these are not as formulaic as this ones.

19 = 548 and a
33 = 968
Find a
27
Answer:
The value of a₂₇ is 788
Step-by-step explanation:
a₁₉ = 548
a₃₃ = 968
Now,
a₁₉ = 548 can be written as
a + 18d = 548 ...(1) and
a₃₃ = 968 can be written as
a + 32d = 968 ...(2)
Now, from equation (2) we get,
a + 32d = 968
a + 18d + 14d = 968
548 + 14d = 968 (.°. a + 18d = 548)
14d = 968 - 548
14d = 420
d = 420 ÷ 14
d = 30
Now, for the value of a put the value of d = 30 in equation (1)
a + 18d = 548
a + 18(30) = 548
a + 540 = 548
a = 548 - 540
a = 8
Now, For a₂₇
a₂₇ = a + 26d
a₂₇ = 8 + 26(30)
a₂₇ = 8 + 780
a₂₇ = 788
Thus, The value of a₂₇ is 788

What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Let us find charges for emily and Jennifer
For Emily
The line passing through points (0, 6) and (6, 8)
Slope =2/6=1/3
y intercept is 6
6=b
Equation is y=1/3x+6
Now let us find for Jennifer (0, 4) and (5, 6)
m=2/5
y intercept is 4
Equation is y=2/5x+4
Now equation both equations
1/3x+6=2/5x+4
1/3x-2/5x=4-6
x(1/3-2/5)=-2
x(5-6)/15=-2

2. If AB = 30, then DC =
Answer:
1. BC=25
2. DC=30
Step-by-step explanation:
In a parallelogram, pairs of opposite sides are always equal. The side opposite of AD is BC, so if AD=25, BC=25. Likewise, if side AB=30, side DC=30. Of course, this is assuming the shape is a parallelogram. If it is not, there is no way of determining the side lengths.
