Answer:
n = -1
Step-by-step explanation:
→The fraction [tex]\frac{n}{5}[/tex] is really just [tex]\frac{1}{5}n[/tex]:
[tex]\frac{1}{5}n = \frac{-1}{5}[/tex]
→To get n by itself, you must multiply both sides by the reciprocal of [tex]\frac{1}{5}[/tex], which is 5:
5 · [tex]\frac{1}{5}n = \frac{-1}{5}[/tex] · 5
n = -1

This chart shows the growth of a maple tree. If the tree's height increases in this same pattern, what will be the height of the tree, in inches, after 8 months?
Months
Height of Tree
1
10 inches
2
13 inches
3
16 inches
4
19 inches
Answer:
31 inches
Step-by-step explanation:
you can get this answer by 2 ways. one is using number patterns.
find the difference between each of the heights.
13-10=3
16-13=3
19-16=3
therefore the common difference is 3
now create a number pattern.
first term + common difference× (n-1)= nth term
a+(n-1)d
let's check this with the 2nd month
10+ 3× (2-1)
10+3=13
in second month 13 inches
so this pattern works
let's find the height in 8th month
10+ 3(8-1)
10+ 21=31 inches
height in 8th month is 31 inches.
you can find this by just adding too. but forming an equation is always good and safe

Answer:
uh say that again slower
Step-by-step explanation:
Point V lies between points U and W on Line segment U W.
A line has points U, V, W. The length between U V is 2 x minus 4. The length between V W is 4 x + 10.
If UW = 9x – 9, what is UW in units?
5 units
6 units
30 units
36 units
Answer:
The correct answer is (d) 36 units.
Step-by-step explanation:
Just took the test on edge :)
The measure of UW is 36 units
The measure of angles between segmentsFrom the question, a line has points U, V, W. If Point V lies between points U and W on Line segment U W, then;
UV + VW = UW
Given the following
VW = 4 x + 10.
UW = 9x – 9
UV = 2x - 4
Substitute
2x - 4 + 4x + 10 = 9x - 9
6x + 6 = 9x - 9
-3x = -15
x = 5
UW = 9x - 9
UW = 45 - 9
UW = 36 units
Hence the measure of UW is 36 units

v
Answer:
10
Step-by-step explanation:
F + V − E = 2
Where F is the number of faces, V is the number of vertices and E is the number of edges
F + 16 - 24 = 2
Combine terms
F -8 = 2
Add 8 to each side
F -8+8 =2+8
F = 10
A customer deposits $500 in an account that pays 4% annual interest. What is the balance after 3 years if the interest is
compounded annually?
Compound interest formula: V(t) =P(1+r/n)^nt
t = years since initial deposit
n= number of times compounded per year
r= annual interest rate (as a decimal)
P= initial (principa) investment
V(t) = value of investment after t years
Answer:
The value of the investment V(t) after t years is $562.43
Step-by-step explanation:
Here, we are interested in calculating the balance V(t) after 3 years given the information in the question.
We are to use the given formula.
From the question;
V(t) = ?
P= $500
t = 3 years
r = 4% = 4/100 = 0.04
n = 1
Substituting these values into the formula, we have ;
V(t) = 500( 1 + 0.04/1)^(3)
V(t) = 500(1.04)^3
V(t) = 562.432
To number the apartments in a building, metal plates with digits were used: one digit on each plate. How many plates were used to number 136 apartments in the building?
Answer:
301 plates
Step-by-step explanation:
For numbers between 0 and 9, 1 plate was used each.
This means that 10 plates were used.
For numbers between 10 and 99, 2 plates were used for each.
This means that the number of plates used will be:
2 * 90 = 180 plates
For numbers between 100 and 136, 3 plates were used for each.
This means that the number of plates used is:
3 * 37 = 111 plates
The total number of plates used is therefore:
10 + 180 + 111 = 301 plates
301 plates were used in total.

What is the solution to the system of equations? y = –5x + 3 y = 1 (0.4, 1) (0.8, 1) (1, 0.4) (1, 0.8)
Answer:
y = –5x + 3....... 1
y = 1 ..........2
Substitute y = 1 into the first equation
y = –5x + 3
1 = - 5x + 3
-5x = 1-3
- 5x = - 2
Divide both sides by - 2
x = 2/5 or 0.4
x = 0.4 y = 1
The solution to the above system of equations is ( 0.4 , 1)

In the figure below, triangle RPQ is similar to triangle RTS.
Triangle R P Q. Side P R is 42 and side P Q is x. Triangle S R T. Side S T is 36 and side R T is 28.
What is the distance between P and Q?
24
42
50
54
Answer:
The distance between P and Q is 54
Step-by-step explanation:
We are given that triangle RPQ is similar to triangle RTS.
Property of similar triangle: The ratio of any pair of corresponding sides is the same.
So, by property : [tex]\frac{RP}{RT}=\frac{PQ}{ST}[/tex]
PR=42
PQ=x
ST=36
RT=28
So,[tex]\frac{42}{28}=\frac{x}{36}[/tex]
[tex]\frac{42 \times 36}{28}=x[/tex]
54=x
Hence the distance between P and Q is 54
Answer:

AABC is isosceles.
mZA = 3x + 40 and mZC = x + 50 mZA = [ ? ]°
Answer:
Using the information from the problem, the measurement of ∠A is 55°
Step-by-step explanation:
We are given that ΔABC is isosceles. If a triangle is isosceles, then it means that two angles are going to be congruent to each other which are called the base angles. In the problem above, ∠A and ∠C are the base angles so that means that their measurements are going to be equal to each other.
We can use this information in order to solve the problem and find the measurement of ∠A. By doing so, we will set up both expressions and equal them to each other.
m∠A = 3x + 40
m∠C = x + 50
3x + 40 = x + 50
Subtract x on both sides of the equation.
2x + 40 = 50
Subtract 40 from both sides of the equation.
2x = 10
Divide 2 on both sides of the equation.
x = 5
So now that we have our x-value, we will plug this into both angles just to check our work. If they have the same measurement, then we have our answer for the measurement of ∠A.
x = 5
m∠A = 3(5) + 40
m∠A = 15 + 40
m∠A = 55
m∠C = (5) + 50
m∠C = 55
So, the two angles have the same measurements to each other which means they are congruent. Now, we have our answer.
The measurement of ∠A is 55°

what is the value of x in 2.5(6x-4)=10+(1.5+0.5)
Answer:
x = 22/15
Step-by-step explanation:
2.5(6x-4)=10+(1.5+0.5)
Combine like terms
2.5(6x-4)=10+(2)
2.5(6x-4)=12
Divide each side by 2.5
6x-4 = 4.8
Add 4 to each side
6x = 8.8
Divide by 6
6x/6 = 8.8/6
x = 88/60
x = 22/15

If Andre made another countryard scale drawing at a scale of 1 to 12, would this drawing be smaller or larger than the first drawing ? Explain your reasoning.
Answer:
smaller
Step-by-step explanation:
If Andre is using a scale of 1:12 then we can safely say that the courtyard drawing will be smaller than his first drawing. This is because this scale means that for every 12 units of measurement on the original the newer version will be 1 unit of measurement. Therefore making the new drawing 12 times smaller than the first one that Andre made.
