Answer:
Perimeter: 17 inches
Area: 8 square inches
Step-by-step explanation:
The ratio of perimeters is the same as the similarity ratio.
JKLM perimeter / ABCD perimeter = P/68 = 1/4
Multiplying by 68, we get ...
P = 68/4 = 17 . . . . inches
__
The ratio of areas is the square of the similarity ratio.
JKLM area / ABCD area = A/128 = (1/4)^2
Multiplying by 128, we get ...
A = 128/16 = 8 . . . . square inches
__
Perimeter = 17 inches
Area = 8 square inches

This means that in each container there are 1.5 cups of jams.
Thus,
Dividing equally 6 cups of jams into 4 containers.
1.5 cups / 1 container
The amount of jam in each container is 1.5 cups of jams.

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
Now,
The slope between (-10, -12) and (-8, -8) is 2.
The slope between (-8, -8) and (-6, -4) is 2.
The slope between (-6, -4) and (-4, 0) is 2.
Therefore,
The slope of the line passing through these points is 2.
The slope between (-4, 2) and (0, 1) is -1/4.
The slope between (0, 1) and (4, 0) is -1/4.
The slope between (4, 0) and (8, -1) is -1/4.
Therefore,
The slope of the line passing through these points is -1/4.
The slope between (-7, -7) and (0, -8) is -1/7.
The slope between (0, -8) and (7, -9) is -1/7.
The slope between (7, -9) and (14, -10) is -1/7.
Therefore,
The slope of the line passing through these points is -1/7.
The slope between (-2, 2) and (0, 3) is 1/2.
The slope between (0, 3) and (2, 4) is 1/2.
The slope between (2, 4) and (4, 5) is 1/2.
Therefore,
The slope of the line passing through these points is 1/2.
The slope between (2, -11) and (4, -25) is -7.
The slope between (4, -25) and (6, -39) is -7.
The slope between (6, -39) and (8, -53) is -7.
Therefore,
The slope of the line passing through these points is -7.
The slope between (-11, -38) and (-5, -14) is 6.
The slope between (-5, -14) and (1, 10) is 8.
The slope between (1, 10) and (7, 34) is 6.
Therefore,
The slope of the line passing through these points is 6.
Now,
The equation in slope intercept form is y = mx + c
where m is the slope of the line and c is the y-intercept.
So,
The slope of y = -4x + 6 is -4 and the y-intercept is 6.
The equation y = -1 represents a horizontal line, so the slope is 0 and the y-intercept is -1.
To find the slope-intercept form, we can rewrite 4r + y = -1 as y = -4r - 1.
Therefore,
The slope is -4 and the y-intercept is -1.
The slope of y = 6x - 4 is 6 and the y-intercept is -4.
To find the slope-intercept form, we can rewrite -x - 4y + 8 = 0 as -4y = x - 8, then divide both sides by -4 to get y = (-1/4)x + 2.
Therefore,
The slope is -1/4 and the y-intercept is 2.
To find the slope-intercept form, we can rewrite 2r - 12y + 10 = 0 as 12y = 2r + 10, then divide both sides by 12 to get y = (1/6)r + 5/6.
Therefore,
The slope is 1/6 and the y-intercept is 5/6.
Thus,
The slope and the y-intercept are given above.

Answers
length of rectangle = ( 4n-5 )
breadth of rectangle = ( 3n-2)
To find :-Area and perimeter of rectangle.
solution :-by the question ,
We know the area of rectangle = length × breadth
Area = (4n -5) (3n-2)
[tex] = {12n}^{2} - 8n - 15n + 10[/tex]
[tex] = {12n}^{2} - 23n + 10[/tex]
now ,
perimeter = 2 ( length + breadth (
= 2 ( 4n-5 + 3n-2)
= 2 ( 7n-7)

A toy rocket lifts off at an initial velocity of 102 feet per second from a height of 10 feet. The height of the rocket can be modeled by the equation h = – 16t2 + 102t + 10, where ‘t' is the time in seconds. When will the rocket hit to the ground?
Answers
Answer:
6.47secs
Step-by-step explanation:
Given the height of the rocket modelled by the equation;
h = – 16t^2 + 102t + 10, where ‘t' is the time in seconds
The rocket will hit the ground at h = 0
Substitute into the equation
– 16t^2 + 102t + 10 = 0
Multiply through by -1
16t^2-102t-10 = 0
t = 102±√(102)²-4(16)(-10)/2(16)
t = 102±√10404+640/32
t = 102±√11044/32
t = 102 ±105.09/32
t = 102+105.09/32
t = 207.09/32
t = 6.47secs
Hence it will take 6.47secs for the rocket to hit the ground
