Answer: 270
Step-by-step explanation:
1) Find DE
1 : 6
17 : x
Cross multiply
x = 17 * 6
x = 102
DE = 102
2) Compare the two triangles
1st (ABC)
side = 45
base = 17
2nd (ADE)
side = x
base = 102
[tex]\frac{x}{45} = \frac{102}{17}[/tex]
Cross multiply
17x = 102 x 45
17x = 4590
x = 4590/17
x = 270
AD = 270

A train decreased its speed by 72 miles hour in 12 minutes. Find the average change in speed per minute.
Answer:
6 mph
Step-by-step explanation:
The average rate of change of the speed of the train will be 6 miles per hour.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that a train decreased its speed by 72 miles per hour in 12 minutes.
As the train is reducing its speed by 72 miles per hour in 12 minutes the average rate of change of the speed will be calculated by dividing the change by the time.
Rate of change = 72 / 12
Rate of change = 6 miles per hour
Therefore, the average rate of change in the speed of the train will be 6 miles per hour.

Answer:
x=70
y=55
Step-by-step explanation:
We can start by finding the opposite angle to 125.
180-125=55
We would use 180 because a line is a straight angle, therefore if you intercept the line both angles would add up to 180.
55 is y because they are equivalent.
the sum of all the angles is always 180 so...
55+55=110
180-110=7

Which statement is true about the relationship between the height of the plant and the number of days?
A. This relationship is a function because the plant can be more than one height at a time.
B. This relationship is not a function because the plant can be more than one height at a time.
C. This relationship is not a function because the plant can only be one height at a time.
D. This relationship is a function because the plant can only be one height at a time.
This relationship is a function because the plant body can be of only one particular height at a time.
A function can be defined as a relationship between a set of inputs having only one output each. In other words, a function is basically a relationship between inputs and outputs; where each input is related to only one output at a time. Functions are said to occur when the recorded value of x is varied each time. Since we know that the height of the plant (the x-value) varies by each day, Therefore it is a function.
thus we can conclude that the correct option for the relationship between the height of the plant and the number of days is option D, which tells that this relationship is a function because the plant body can only be of one particular height at a time.

Answer:
Step-by-step explanation:
Convergent: Two plates are coming together. This results in one or both edges of the plates to move upwards to form mountains. If one plate is pushed down while the second is pused up, a deep trench may form (ocean trenches). Volcanoes and earthquakes may also form along this boundary. The Pacific "Ring of Fire" is due to convergent plate collisions.
Divergent: Divergent boundaries occur when two plates move away from each other. Earthquakes and volcanoes are common as the growing gap allows magma to comes to the surface. Iceland is divided between the North American and Eurasian plates and this has produced an ever-widenng gap down the center of the country, which is both a major tourist attraction and a source for volcanic activity and numerous hot spring pools. One bridge across this gap is known as the "Bridge Between Continents," and is designed to accomodate the Xcm/year stretch as the continents separate even further.
Transform: Two plates slide past each. The San Andreas fault is one of the more famous. Structures, both natural and man-made, that cross a transform boundary can be split into pieces and moved in opposite directions. Rocks along the boundary are pulverized as the plates grind them. This can result in a linear fault valley or undersea canyon. Earthquakes are common along these faults. Unlike convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed as with convergent and divergent boundaries.

The sum of the measure of angle of a triangle = 180° .
Given two angles = 92° and 72°

Answer:
the answer is 16!
no need to explain just answer
Answer:
5
Step-by-step explanation:
The whole angle is 180 degrees.
90 degrees is already taken by the angle dividing the two vertical angles.
So you have 90 degrees left. then you have to subtract 49 from 90 to get the angle of '5t+6'.
So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.

Line j passes through the points (-5,-2)
and (5,4).
Line k passes through the point
(-3,6) and is perpendicular to line j.
Find an equation for line k.
**the answer is probably in slope intercept form.
Answer:
y = - 5/3x + 1
Step-by-step explanation:
Slope of line j = (-2-4)/(-5-5)
Slope = -6/-10 = 3/5
Slope of the perpendicular line k: -5/3
Point of line k: (-3,6)
y-intercept of line k = 6 - (-5/3)(-3) = 6 - 5 = 1

5) ~The affect of the inequality sign didn't change. If you add or subtract the same positive or negative number to both sides of an inequality or an equation, the inequality stays the same. If you multiply or divide both sides of an inequality or an equation by the same positive number, the inequality stays the same. This is because when manipulating inequalities there are rules this if a < b then a + c < b + c so we get a new number that replaces a and b yet the inequality symbol stays the same so a still is smaller than b.

Let's call Ahmed's number x,
If he multiplies it by 2, it becomes 2xHe then divides it by 5 so it would be 2x ÷ 5The result was 4, so it would be written as 2x ÷ 5 = 4To solve for x,
First, multiply both sides by 5: 2x = 20Finally divide both sides by 2 to get x on its own: x = 10Answer: He was thinking of the number 10You could also work backwards:
If he ×2 then ÷5, you would ×5 then ÷2 (doing the opposite):
4 × 5 = 2020 ÷ 2 = 10Hope this helps!

A.Commutative Property of Addition
B.Commutative Property of Multiplication
C.Associative Property of Addition
D.Associative Property of Multiplication
(7a*2b)+3c=3c+(7a*2b) the property for the given expression is Option A) Commutative Property of Addition.
The given expression is (7a*2b) + 3c = 3c + (7a*2b). This equation demonstrates the Commutative Property of Addition.
The Commutative Property of Addition states that the order in which numbers are added does not affect the result.
In mathematical terms, it can be written as: a + b = b + a.
In your expression, you have terms involving both addition and multiplication. However, since addition is involved on both sides of the equation, we can focus on the addition aspect.
(7a*2b) + 3c = 3c + (7a*2b)
First, we can rearrange the terms on the left side:
7a*2b + 3c = 3c + 7a*2b
Now, observe that the terms on both sides of the equation are the same: 7a*2b and 3c.
They are just arranged in a different order. This aligns with the Commutative Property of Addition, which says the order of addition doesn't matter.
Therefore, the expression is an illustration of this property, and the correct answer is the Commutative Property of Addition (A).
In summary, the expression shows that changing the order of terms within an addition does not change the result, thus demonstrating the Commutative Property of Addition.
