The actual length of a building is 168 feet and its width is 152 feet. If the scale length of the bulding in the drawing is 21 inches and the width is 19 inches what scale was used in the drawing

Answer:

a)  $498

b) $1052

c) $554

Step-by-step explanation:

to find the median of lower half of data:  find median of all the data, then find middle value from the minimum value to the median (not including median)

to find the median of upper half of data:  find median of all the data, then find middle value from the median to the maximum value (not including median)

interquartile range (IQR) is the difference of the two

Answer:

112*

Step-by-step explanation:

The easy way to figure this out is to take the two numbers we do have and add them together. 50 + 62 = 112

We now now the complete angle if that line was not there in the middle. and sice that angle is the same at angle X it is automatically the same, 112. If you don't understand please comment and let me know.

Answer:

a) 3x²-4x-15

b) binomial

Answer:

x = 9 (it is seriously not drawn to scale)

Step-by-step explanation:

BC = DC^2 + BD^2 (Pythagorean theorem)

BC = 4^2 + 6^2

BC = 16 + 36

BC = 52^2

BC = 2sqrt13

BC/AB = DC/BD

(2sqrt13)/AB = 4/6

6(2sqrt13) = 4(AB)

12sqrt13 = 4AB

3sqrt13 = AB

AC^2 = AB^2 + BC^2 (Pythagorean Theorem)

AC^2 = (3sqrt13)^2 + (2sqrt13)^2

AC^2 = 117 + 52

AC^2 = 169

AC = 13  

AD + DC = AC

AD + 4= 13

AD = 9

Step-by-step explanation:

The sum of the measure of the interior angles in a triangle is 180°

m∠D + m∠E + m∠F = 180°

34°  + m∠E + 117° = 180°

     m∠E = 29°

Answer:

0.98

Step-by-step explanation:

0.98 would be the most logical answer. If there is a 0.2 percent chance, it has a 20% chance of happening, which isn't likely. If there is a 0.5 percent chance, it is split so it can't really be likely or unlikely. Whereas having a 0.98 percent chance means there's a 98% of it happening.

Answer:

B/ it represents a perfectly linear positive correlation between x and y

Step-by-step explanation:

correlation

of -1.0 indicates a perfect negative correlation, and a correlation of 1.0 indicates a perfect positive correlation.

The correlation coefficient for the data represents a perfectly linear positive correlation between x and y.

It means the variable should be shifted together by having the similar percentage and the direction.

Here it shows the direct relationship between two variables it can be anything like the demand for the product, and the price of the product.

hence, The correlation coefficient for the data represents a perfectly linear positive correlation between x and y.

Given:

The figure of a triangle DEF.

To find:

The coordinate of image of given triangle after reflection over y-axis.

Solution:

The vertices of given triangle are D(1,4), E(4,3), F(2,0).

If a figure is reflected over the y-axis, then the rule of reflection is

[tex](x,y)\to (-x,y)[/tex]

Using this rule, we get

[tex]D(1,4)\to D'(-1,4)[/tex]

[tex]E(4,3)\to E'(-4,3)[/tex]

[tex]F(2,0)\to F'(-2,0)[/tex]

Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).

Answer:

x=1

Step-by-step explanation:

given

21=14+7x

our objective is to get the variable (x) by itself

To do so we use inverse operations

so to get rid of the 14 we subtract 14 but whatever you do to one side you have to do to the other so we subtract each side by 14

14-14 cancels out

21-14=7

now we have

7x=7

now we want to get rid of the 7

to do so we divide by 7 but remember whatever we do to one side we have to do to the other side so we divide each side by 7

7/7 cancels out

7/7=1

we're left with x=1

hope this helps!

Answer:

NA = A + w is the correct answer

Step-by-step explanation:

just took the quiz :)

Its new area (NA) in terms of its old area (A) is NA = A + w

We have given that,

Area=L x W

If we add one unit to the length (l) of a rectangle that has a width (w),

Then we get the area that is

NA = A + w

Therefore option tree is correct.

Answer:

D

Step-by-step explanation:

3x+9+6=6

step 1 combine like terms

9+6=15

now we have

3x+15=6

step 2 subtract each side by 15

15-15 cancels out

6-15=-9

now we have

3x=-9

step 3 divide each side by 3

3/3 cancels out

-9/3=-3

x=-3

The reason it can also be -3 is because I I means absolute value and the absolute value of negative 3 is positive 3

Answer:

Step-by-step explanation: both graphed is D

The graph D represents the solution of the system of the equation.

One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given, the system of equation;

y = -3x - 5  {equation 1}

y = 3x + 1  {equation  2}

Add both of the equation:

2y = -4

y = -2

And x = 1

And the solution set is (1 , -2).

And only D have the solution set (1 , -2)

Therefore, the graph D represents the solution of the system of the equation.
