solve equation by taking square roots n^2+4=40
Answer:
n = ±6
Step-by-step explanation:
n² + 4 = 40
n can be solved by finding the square root
n² = 40 - 4
n² = 36
n = √36
n = ±6
Which statement is supported by the histograms? The two data sets have the same distribution and same range. The two data sets have the same distribution but different ranges. The two data sets have different distributions but the same range. The two data sets have different distributions and different ranges.
Answer:
The two data sets have different distributions and different ranges.
Step-by-step explanation:
When you subtract for both of the ranges they are different numbers. So that's the second part. The numbers along the bottom are different too so that is the different distributions.
Answer:
The two data sets have different distributions and different ranges.
Step-by-step explanation:
The shape of the data for German male adult heights is skewed left, but the shape of the data for female adult heights is close to symmetric. So, the two data sets have different distributions.
Each data set has the same minimum height of 145 centimeters. However, the maximum male adult height is 220 centimeters, and the maximum female height is 185 centimeters. So, the two data sets have different ranges.

Answer:
AA Theorem
Step-by-step explanation:
In order to prove AB/AE = AC/AD, we need to prove that the triangles are similar. The AA Theorem says that if two triangles share two congruent angles, then the triangles are similar. The given states that ∠ABE ≅ ∠ACD, which means these two angles are congruent.
For the second angle, both triangles have the angle by point A. These angles can be written as ∠A ≅ ∠A. These angles are congruent because of the reflexive property.
Because we have proven these triangles to be simliar, we know the proportion AB/AE = AC/AD is correct because corresponding sides of similar triangles are proportional.

△ABC and △JKL have corresponding equal angles. Side length BC is twice the length of side KL. Which statement is true? A. △ABC and △JKL are similar. B. △ABC and △JKL are congruent. C. There is not enough information to know if they are similar or not. D. △ABC is a dilation of △JKL by a factor of 12
Answer:
A. △ABC and △JKL are similar.
Step-by-step explanation:
Since three angles of one triangle are congruent to three corresponding angles of the other triangle, the triangles are either congruent or similar. Since the side of one triangle is twice the length of the corresponding side of the other triangle, then the triangles are not congruent, but they are similar.
A. △ABC and △JKL are similar.
Answer:
. △ABC and △JKL are similar.

Independently simplify this expression and be ready to share your answer and
the strategy used: 10 1/2 - 3/4
Answer:
9 3/4
Step-by-step explanation:
Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.
10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4
= 10 -1/4
= 9 3/4
__
Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.
10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)
= 10 3/4 -1
= 9 3/4
_____
We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.

Answer:
18) Area= 5*5/2=25/2=12.5 unit ^2
19) Area=AB^2V3/4=8a^2*V3/4=2V3a^2
Step-by-step explanation:
18. A(-3,0)
B(1,-3)
C(4,1)
AB=V(-3-1)^2+(0+3)^2=V16+9=V25=5
AC=V(-3-4)^2+(0-1)^2=V49+1=V50=5V2
BC=V(1-4)^2+(-3-1)^2=V9+16=V25=5
so AB=BC=5
and AC^2=AB^2+BC^2
so trg ABC is an isosceles right angle triangle (<B=90)
Area= 5*5/2=25/2=12.5 unit ^2
19. A(a,a)
B(-a,-a)
C(-V3a, V3a)
AB=V(a+a)^2+(a+a)^2=V4a^2+4a^2=V8a^2
AC=V(a+V3a)^2+(a-V3)^2=Va^2+2a^2V3+3a^2+a^2-2a^2V3+3a^2=V8a^2
BC=V(-a+V3a)^2+(-a-V3a)^2=V8a^2
so AB=AC=BC
Area=AB^2V3/4=8a^2*V3/4=2V3a^2

If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.
Please show all work and not just the answers.
Answer:
x = 2
AB = 15
BC = 15
AC = 30
Step-by-step explanation:
Given that B is the midpoint of AC, then AB = ½ of AC.
AB is given as 3(3x - 1),
AC = 5(2x + 2),
Therefore:
[tex] 3(3x - 1) = \frac{1}{2}*5(2x + 2) [/tex]
Solve for x
[tex] 9x - 3 = \frac{5}{2}(2x + 2) [/tex]
Multiply both sides by 2
[tex] 2(9x - 3) = \frac{5}{2}(2x + 2)*2 [/tex]
[tex] 18x - 6 = 5(2x + 2) [/tex]
[tex] 18x - 6 = 10x + 10 [/tex]
[tex] 18x - 10x = 6 + 10 [/tex]
[tex] 8x = 16 [/tex]
Divide both sides by 8
[tex] x = 2 [/tex]
[tex] AB = BC = 3(3x - 1) [/tex]
Plug in the value of x
[tex] AB = BC = 3(3(2) - 1) [/tex]
[tex] = 3(6 - 1) = 3(5) = 15 [/tex]
[tex] AC = 5(2x + 2) [/tex]
[tex] AC = 5(2(2) + 2) [/tex]
[tex] AC = 5(4 + 2) = 5(6) = 30 [/tex]

[tex]\overrightarrow{AB}=\overrightarrow{OA}-\overrightarrow{OB}= \left[\big5\atop\big3\right]-\left[\big2\atop-\big5\right]= \left[\big5-\big2\atop\big3-(-\big5)\right]=\left[\big3\atop\big8\right][/tex]
2. Calculating length of [tex]\overrightarrow{OA}\,,\ \overrightarrow{OB}\ \text{and}\ \overrightarrow{AB}[/tex]:
[tex]|\overrightarrow{OA}|=\sqrt{5^2+3^2}=\sqrt{25+9}=\sqrt{34}\approx5.831\\\\ |\overrightarrow{OB}|=\sqrt{2^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}\approx5.385\\\\ |\overrightarrow{AB}|=\sqrt{3^2+8^2}=\sqrt{9+64}=\sqrt{73}\approx8.544[/tex]
3. Calculating perimeter:
[tex]P=|\overrightarrow{OA}|+|\overrightarrow{OB}|+|\overrightarrow{AB}|=\sqrt{34}+\sqrt{29}+\sqrt{73}\approx5.831+5.385+8.544=19.76[/tex]

What was the population density of Rio de Janeiro in people per square meter?
Complete question:
In 2016, the city of Rio de Janeiro had a population density of 5377 people/km2.
What was the population density of Rio in people per square meter?
Answer:
0.005377 peope/m²
Step-by-step explanation:
Given that :
Population density of Rio in 2016 = 5377 people/km²
To obtain population density in people per square meter, we convert 5377people/km² to people per m²
Recall:
1000 m = 1km
Hence,
5377 people/km² = 5377 people / (1000²)m
= (5377/1000000)people/m²
= 0.005377 peope/m²

There were 7 songs on one side of a record. It took 20 minutes and 18 seconds to play the side. What is the average number of seconds per song?
i will mark brainliest
Answer:
174 seconds.
Step-by-step explanation:
So there was a total of 7 songs.
And it took a total of 20 minutes and 18 seconds to play them all.
20 minutes and 18 seconds is the same as 20(60)+18=1218 seconds.
Thus, the average number of seconds per song was:
[tex]1218/7=174[/tex]
174 seconds,
or about 2 minutes and 54 seconds.

A grocery store has small bags of apples for 5$ and large bags of apples for 8$. If you buy 6 bags of apples and spend 45$, how many of each bags did you buy?
Answer:
He bought 1 small bag and 6 large bags.
Step-by-step explanation:
We can set up 2 equations with the given information.
5x+8y=45
x+y=6
We can rearrange the second equation to solve for x.
x=6-y
Now we substitute x for 6-y in the first equation
5(6-y)+8y=45
30-5y+8y=45
30+3y=45
y+10=15
y=5
x=1
He bought 1 small bag and 6 large bags.
a line of best fit for the data is y=0.9x-4.5, where x represents age in year, and in years, and y represents hourly pay, in dollars.Based on the data, what is the best prediction for the hourly pay of a 25 year old?
Answer:
$18
Step-by-step explanation:
Given:
y = 0.9x - 4.5
Where,
x = age in years
y = hourly pay in dollars
what is the best prediction for the hourly pay of a 25 year old?
That is, find y when x=25
y = 0.9x - 4.5
= 0.9(25) - 4.5
= 22.5 - 4.5
= 18
y = $18
The prediction for the hourly pay of a 25 year old is $18
Answer:
$18:00

This means that 2 different y-values cannot have the same x-value.
A health club charges an initiation fee of $50. Members then pay $45 per month. You have $400 to spend on a health club membership. For how many months can you afford to be a member? Let n represent the number of months you can pay for a membership.
Answer:
8 monthsStep-by-step explanation:
In this problem we must first of all write the inequality that describes the problem.
Given that
1. you have a limit of $400
2. there is an initial fee of $50
3. monthly payment is $45
let the number of months be n
therefore
[tex]50+45n\leq 400\\\\45n\leq 400-50\\\\45n\leq350[/tex]
Divide both sides by 45 we have
[tex]n\leq \frac{350}{45} \\\\n=\frac{70}{9} \\\\n= 7.77\\\\[/tex]
approximately you are going to be member for 8 months
