The inverse proportionality expression is y =40/x
Inverse proportionIf the variable y is inversely proportional to x, this is expressed as;
y = k/x
where
k is the constant of proportionality
If y = 5 and x = 8. then;
5 = k/8
k = 5 * 8
k = 40
Determine the inverse proportionality
Recall that y = k/x
y = 40/x
Hence the inverse proportionality expression is y =40/x

Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator. 45 L to 56 L
Answer:
45/56
Step-by-step explanation:
We have,
Numerator = 45 L
Denominator = 56 L
We need to find the ratio as a fraction in simplest form. So,
[tex]\dfrac{N}{D}=\dfrac{45}{56}[/tex]
As there is no common factor between 45 and 56. It means the simplest fraction is 45/56.

From his home Craig would have to walk due north to get to his friend Devon's house and due east to get to his friend Dereks house.it is 4 miles from Craigs house to derricks House and a straight line distance of 5 miles from devon house to derricks House how far is Craig's house from Devon's house
Answer:
3 miles
Step-by-step explanation:
This is because Derek would be your right angle of the corner of the right triangle. And since the distance is both of those houses from Derek’s house, you would have to use the Pythagorean Theorem to find the difference of the hypotenuse and the leg

.....20 points
Answer:
B
Step-by-step explanation:
The simplest way to do this is to take every integer on there and divide it by 3.
8961/3 = 2987
5233/3 = 1744 1/3
10245/3 = 3415
-5469/3 = -1823
Because B does not produce an integer, that is your answer
(This works because of inverse operations)

The length of a rectangle is three meters more than its width the perimeter of the rectangle is 74 meters what are the dimensions of the rectangle
Answer:
17 meters x 20 meters
Step-by-step explanation:
perimeter = 2 widths + 2 lengths
74 = 2W + 2L
L = W + 3
substitute for L
74 = 2W + 2(W + 3)
74 = 4W + 6
68 = 4W
W = 17 meters
L = 20 meters
Answer:
Step-by-step explanation:
Givens
Let the width = w
Then the Length = w + 3
Formula
P = 2L + 2W
P = 74
Solution
Substitute w + 3 for L
2(W + 3) + 2W = 74 Remove the brackets
2W + 6 + 2W = 74 Collect Like Terms
4w + 6 = 74 Subtract 6 from both sides
4w = 74 - 6
4w = 68 Divide by 4
w = 68/4
w = 17
L = w + 3
L = 17 + 3
L = 20
Check
P = 40 + 34
P =74

slope. Choose two points. For the sake of explainin, I am choosing
(-3,1)
and (0,3). That’s the y intercept!!
The slope is the rate of increase. We have to measure it like we do with stairs. The rise divided by the run
the rise is 2. See the picture. The run is 3(change in x) the x increases by 3 between 2 integer points while the y changes by 3(change in y —>3 minus 1)
Rise= 3
run =2
Slope=rise/run=3/2

Two triangles A B C and D F G. A B is 5 inches. B C is 6 inches. A C is 7 inches. D F is 15 inches. F G is 18 inches. Angle B is congruent to angle F.
Answer:
C
Step-by-step explanation:
Since every side of ΔABC is dilated by 3, or triple the size
We multiply every length of ΔABC by 3
But the length of DF and FG are already done for us but DG is not, which is essential to finding the answer
7 x 3 = 21
DG = 21
5/7 = 15/21
5 ÷ 7 = 0.71
15/21 = 0.71
5/7 = 15/21
Value of [tex]\boldsymbol{DG}[/tex] in a triangle [tex]DFG[/tex] is equal to [tex]\boldsymbol{21}[/tex] inches. To understand the calculations, check below.
Define similar triangles.Two triangles are said to be similar if their sides are proportional and their angles are equal.
Triangles [tex]ABC,DFG[/tex] are similar
[tex]\frac{AB}{DF}=\frac{BC}{FG}=\frac{AC}{DG}[/tex]
[tex]\frac{5}{15}=\frac{7}{DG}[/tex]
[tex]DG=21[/tex] inches
So, value of [tex]DG[/tex] is equal to [tex]\boldsymbol{21}[/tex] inches
