63.7786879082 rounded to the nearest tenth

Answers

Answer:

63.8

Step-by-step explanation:

63.77 so you look at the hundredths 5 or higher round up

63.8 is the required answer

The given number is 63.7786879082, we have to round to the nearest tenth

How to round nearest 10th?

To round the decimal number to its nearest tenth, look at the hundredth number. If that number is greater than 5, add 1 to the tenth value.

63.7786879082

We can see that 100th number i. e 7 is greater than 5, so add 1 to the tenth value

So we get 63.8

Find the value of x in each case:
L, M ∈ KN

Answers

Answer:

x = 27

Step-by-step explanation:

From the picture attached,

m∠PLM + m∠PLK = 180° [Linear pair of angles are supplementary]

m∠PLM + 3x = 180°

m∠PLM = 180° - 3x

Similarly, m∠PML + m∠PMN = 180° [Linear pair of angles]

m∠PML + (2x + 72)° = 180°

m∠PML = 180° - (2x + 72)°

From triangle PLM.

m∠PLM + m∠PML + m∠LPM = 180° [Sum of interior angles of a triangle = 180°]

(180 - 3x) + 180 - (2x + 72) + x = 180

180 - 3x - 2x - 72 + x = 0

-4x + 108 = 0

x = [tex]\frac{108}{4}[/tex]

x = 27

D) foot length, arm span is predicted to increase by about 0.186 cm.

Answers

Answer:

C. arm span, foot length is predicted to increase by about 0.186 cm.

Step-by-step explanation:

C) arm span and foot length are predicted to increase by about 0.186 cm.

What is linear regression?

Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable.

Given, The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot.

let "FL" be the foot length and "AS" be the Arm span.

Slope = Δy/Δx = ΔFL/ΔAS

ΔFL/ΔAS = 0.186

ΔFL = ΔAS* 0.186

thus an increase in AS by 1 cm will lead to an increase in FL by 0.186cm

Therefore,  the slope of the least-squares regression line means for each additional centimeter C) arm span, foot length is predicted to increase by about 0.186 cm.

How do I turn something like this: 3x - 2y = -16

[tex]3x - 2y = - 16[/tex]

Subtract sides -3x

Theequationforlinegcanbewrittenas y = –9 4 x − 1 . Line h , whichisperpendiculartoline g , includesthepoint (10, 4) . What istheequationofline h ? Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.

Answers

Answer:

y-4 = 4/9(x-10)

Step-by-step explanation:

Given the equation of the line g to be y = -9/4 x - 1.

To find the equation of a line h perpendicular to this line, the following steps must be taken;

First find the slope of the known line g

The standard equation of a line is y = mx+c where

m is the slope

c is the intercept

Comparing this equation with the given equation y = -9/4 x -1, it can be seen that the slope of the line g is -9/4

Next is to find the slope of the line h

Since the line g is perpendicular to h, then the product of their slope will be -1 i.e mh*mg = -1

mh = -1.mg

mh = -1/(-9/4)

mh = -1*-4/9

mh = 4/9

Hence the slope of the line h is 4/9

Find the intercept of line h

To get this, you will substitute the slope m and the point into the equation y = mx+c

m = 4/9

(x,y) = (10,4)

4 = 4/9(10) + c

4 = 40/9 + c

c = 4-40/9

c = (36-40)/9

c = -4/9

Hence the intercept of the line h is -4/9

Finally, find the equation of the line h in slope-intercept form

The slope-intercept form of a line is expressed as y = mx+c

y-y0 = m(x-x0)

Given

m = -4/9

x0 = 10

y0 = 4

Substitute:

y-4 = 4/9(x-10)

Hence the equation in slope-intercept form is y-4 = 4/9(x-10)

Answers

Answer:

m=10

Step-by-step explanation:

Answer:

m=10

Step-by-step explanation:

9(m+5)−3(m−2)=8m+31

Step 1: Simplify both sides of the equation.

9(m+5)−3(m−2)=8m+31

9m+45+−3m+6=8m+31

(9m+−3m)+(45+6)=8m+31(Combine Like Terms)

6m+51=8m+31

Step 2: Subtract 8m from both sides.

6m+51−8m=8m+31−8m

−2m+51=31

Step 3: Subtract 51 from both sides.

−2m+51−51=31−51

−2m=−20

Step 4: Divide both sides by -2.

m=10

Jacob received 685 votes in the school election.
If he received 125 more than 2/3 of the total
number of votes, how many students voted in
the election?

Answers

Answer:

840

Step-by-step explanation:

He gets 685 votes. This is 125 more than 2/3 of the total number of votes. So 2/3 must be 125 less than 685.

2/3=560

So ÷2 to find 1/3, because 2/3 ÷2 = 1/3.

1/3=280

So then you x3 because 1/3x3=3/3, or 1 whole.

1 whole=840

840=total number of votes
