Answer:
the expression of perimeter is 2(l+b)
✓15
Is this rational or irrational
Answer:
irrational
Step-by-step explanation:
√15 is not a rational number it's a irrational number
:-))
Answer:
Irrational
Step-by-step explanation:
Rational numbers are those that can be written in the form a/b where a and b are both integers with no common factors.
sqrt15 cannot be written in that form, therefore it is irrational.
Triangle ABC has vertex coordinates A(0, -3), B(-1,0), and C(-2, -1). It is
reflected across the x-axis. What are the coordinates of A'B'C?
O A. A'(3,0), B'0,1),C'(1.-2)
B. A'(0,3). B'(-1,0).C1-2,1)
C. A'0.-3).B'(1,0).C12,-1)
D. A'(-3,0).B'0.-1).C'(-1,-2)
9514 1404 393
Answer:
B. A'(0,3), B'(-1, 0), C'(-2, 1)
Step-by-step explanation:
The transformation for reflection across the x-axis is ...
(x, y) ⇒ (x, -y) . . . reflection across the x-axis
Then ...
A(0, -3) ⇒ A'(0, 3) . . . . . . matches choice B only

i need help with finding area whats the area of a 11ft an 6ft rectangle
Hello!
[tex]\large\boxed{A = 66ft^{2}}[/tex]
Formula for the area of a rectangle:
A = b × h where:
b = base
h = height
We are given the base and height as 11 ft and 6 ft, so use the equation above to solve for the area:
A = 11ft × 6ft
A = 66ft²

The value of 3(2)ˣ for x = -1 is 3/2
What is simplification?In mathematics, simply or simplification is reducing the expression/fraction/problem to a simpler form. It makes the problem easy with calculations and solving.
Given is a function, f(x) = 3(2)ˣ
When x = -1
f(-1) = 3(2)⁻¹
f(-1) = 3x2⁻¹
f(-1) = 3x1/2
f(-1) = 3/2
Hence, The value of 3(2)ˣ for x = -1 is 3/2

EFGH is an isosceles trapezoid. If EH=4x-27 and FG=x+9, find the value of x.
PLEASE HELP ASAP!
Answer:
If EFGH is an isosceles trapezoid,
if
EH=4x-27+
FG=x%2B9+
EG=3y%2B19
FH=11y-21
then EH=FG and EG=FH
set up equations:
4x-27=x%2B9 .......solve for x
4x-x=27%2B9
3x=36
x=36%2F3
3y%2B19=11y-21.......solve for y
11%2B19=11y-3y
30=8y
y=30%2F8
y=15%2F4
y=3.75
so,x=12 and y=3.75
you can also check the length of equal sides and equal diagonals:
EH=4%2A12-27+=21
FG=12%2B9+=21
EG=3%283.75%29%2B19=30.25
FH=11%283.75%29-21=30.25x=12

Answer:
The value of [tex]x[/tex] is 10º.
Step-by-step explanation:
From Euclidean Geometry we remember that the sum of internal angles within a triangle equals to 180º. We present the resulting triangle after applying some geometric handling in the image attached below. Then, the triangle satisfies the following equation:
[tex]100^{\circ} + (80^{\circ}-5\cdot x)+(4\cdot x +10^{\circ}) = 180^{\circ}[/tex] (1)
[tex]190^{\circ} - x = 180^{\circ}[/tex]
[tex]x = 10^{\circ}[/tex]
The value of [tex]x[/tex] is 10º.

Step-by-step explanation:
And remember the little $4308 pizza-mistake? How many weeks would you have
to work to pay for this mistake with the $13 bounced check? Round up to the next
whole week.
weeks
It required 332 weeks to pay the whole amount.
Given that,
Amount to repay = $4308
Amount to be repaid in a week = $13
The number of weeks that will be consumed is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Let the number of weeks be x,
By arithmetic operations
13x = 4308
x = 4308 / 13
x = 331.34
x ≈332 weeks
Thus, It required 332 weeks to pay the whole amount.

A 24-foot ladder leaning against a wall makes a 30 ° angle with the ground . How high up on the building is the top of the ladder ?
HELP ASAP
Answer:
[tex]12\:\mathrm{ft}[/tex]
Step-by-step explanation:
When the ladder is leaning against the wall, a 30-60-90 triangle is formed. The ladder acts as a 24-foot hypotenuse. Because the height is facing the [tex]30^{\circ}[/tex] angle, the height is half the hypotenuse (30-60-90 rules). If you forget the side rules for a 30-60-90 triangle, simply use basic trig on the right triangle:
[tex]\sin 30^{\circ}=\frac{h}{24},\\h=24\sin 30^{\circ},\\h=24\cdot \frac{1}{2},\\h=\fbox{$12\:\mathrm{ft}$}[/tex].
