Answer:
7
Step-by-step explanation:
If a system decreases by 12% it's the same as multiplying it by .12-1 or .88
This means we can create the following equation
computer value=5300(.88)^n
where n is the number of years
We can then plug in the value of the computer and solve for n
2200=5300(.88)^n
Divide by 5300 and get
.415=.88^n
Then put this into log form and get
Evaluate this into your calculator and get n=6.69 which I would probably just round to 7
The distance between the school and the library is less. Then the library is closer to school.
<h3>What is dilation?</h3>
Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
There is no effect of dilation on the angle.
On one map of a town, the scale from the town to the map is 12mi:3cm.
The school is 2.5cm from the grocery store on this map.
Then the distance between the school and the grocery store will be
⇒ (12 / 3) x 2.5
⇒ 10 miles
On a different map of the same town, the scale from the town to the make is 12mi: 2cm.
The school is 1.5cm from the library on that map.
Then the distance between the school and the library will be
⇒ (12 / 2) x 1.5
⇒ 9 miles
Thus, the distance between the school and the library is less.
Then the library is closer to school.

Answer:
1.25
Step-by-step explanation:
Because they are equal triangles, all of their sides are equal
so, lets take one side of each triangle (4, 5)
the law:
the scale factor = the larger side ÷ the smaller side
x = 5 ÷ 4
x = 1.25
For checking:
the larger side = the smaller side × the scale factor
Y = 4 × 1.25
Y = 5
Answer: 345.4
Step-by-step explanation:
SA=2πr^2+2πrh
SA=2(3.14)(5)^2+2(3.14)(5)(6)
SA=2(3.14)(25)+2(3.14)(30)
SA=2(78.5)+2(94.2)
SA=157+188.4
SA=345.4
The equation must be 4x + y = 17
I will use the y-intercept slope version
y = - 4x + 17
Then the slope is negative (-4) and the y-intercept is 17.
The line passes through the points (0,17) and (0,17/4). The negative slope indicates that the line goes down from left to right (y decreases when x increases).
