If the digit in the unit place of a number is either 2 or 8, the digit in unit place of its square will be??

Answer:

1) 36 + 50 = 86 : Addition property of equality

2) m<D = m<ADB : If two angles have the same measure, then they are equal.

3) <D congruent to <ADB : if two angle are equal, then they are congruent.

4) <D, <ADB are alternate interior angles: assumed from diagram

5) CD // AB : if alternate interior angles are congruent, then the 2 lines cut by a transversal are //.

6) 130 + 50 = 180 : addition property of equality

7) m<E, m<BAE are supplements : if the sum of two angles equal to 180, then they are supplements.

8) <E, <BAE are same-side interior angles : assumed from diagram

9) EF // AB : if same-side interior angles are supplements, then the 2 lines cut by a transversal are //.

10) CD // EF : if two lines are // to the same line, then they are //.

im pretty sure this is the proof

Answer:

Step-by-step explanation:

For two lines to be perpendicular to each other the product of their slopes must be -1.

First we need the slope of the reference line. Since

y=mx+b, where m is the slope and the line we are given is

y=2x-4

So we know the slope is 2. So our perpendicular will satisfy

m1(m2)=-1

2m=-1

m= -1/2

So now our line is

y=-x/2+b, using point (0,-7)

-7=-0/2+b

-7=b, now we have the complete line

y=-x/2-7

(Or more neatly)

y=(-x-14)/2

Answer:

check Analyzing Bivariate Data plots!!

Step-by-step explanation:

45--120

75--215

145--400

The required expression for climbing the rock formations is given as y = 95x + 25.

Given,

[x]Climb Height (feet) Time (minutes)(y)

1                120

2               215

3               400

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
The standard linear equation is given as,
y -y₁ =(y₂ - y₁) /  (x₂ - x₁) (x - x₁)

put the values from the data table,

y - 120 = [(215-120)/(2-1)](x - 1)
y = 95(x - 1) + 120
y = 95x - 95 + 120
y = 95x + 25

Thus, the required expression for climbing the rock formations is given as y = 95x + 25.

Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason

Answer:Jason has read  7 mystery novels and Judy has read  17 mystery novels

Step-by-step explanation:

Total number of mystery books read by  Jason and Judy =24

Let Number of mystery books read by Jason=x

and  Number of mystery books read by Judy= 3x-4

So that the total number of book read by both of them will be expressed as

x +(3x-4) =24

x +3x-4 =24

4x=24+4

4x=28

x=28/4=7

There fore  Jason has read  7 mystery novels

and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

[tex]Diagonal=\sqrt{length^2+width^2}[/tex]

[tex]Diagonal=\sqrt{(50)^2+(55)^2}[/tex]

[tex]Diagonal=\sqrt{2500+3025}[/tex]

[tex]Diagonal=\sqrt{5525 }[/tex]

On further simplification, we get

[tex]Diagonal=74.3303437[/tex]

[tex]Diagonal\approx 74.3[/tex]

Therefore, the length of the required fencing is 74.3 yards.

Answer:

Below.

Step-by-step explanation:

First find the perpendicular  height of the pyramid.

The median of one of the faces, the height and  and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:

5^2 = 2^2 + h^2

h^2 = 5^2 - 2^2 = 21

h = √21 inches.

The volume of the pyramid V = 1/3 * h * area of the base, so

V = 1/3 * 4^2 * √21

= 24.44 in^3 to nearest hundredth.

The volume of a right square pyramid will be (16√21) / 3 cubic units.

Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.

Then the volume of the pyramid will be

Volume = (1/3) × A × h

The slant height is given as.

l² = (half of side)² + h²

A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.

Then the height of the pyramid will be

5² = (4/2)² + h²

h² = 25 - 4

h = √21 inches

Then the volume of a right square pyramid will be

Volume = (1/3) × 4 × 4 × √21

Volume = (16√21) / 3

Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.
