THis is isosceles triangle
180-90-45=45
used pyagorous therum thingy
10over2= square root of 200
so c2=asquare X b squared in this case x=y
so 200/2 = 100
x=100square
y=100 square
simplify = 10

PLEASE HELPP I NEED IT A S A P WILL MARK BRAINLIESTTTT!!!!!
Answer:
-6x - 19y - 56Step-by-step explanation:
Simplify:
-8(2x) + 5(2x - 12) + -2(5y - 2) + (-3) (3y) =-16x + 10x - 60 - 10y + 4 - 9y = x(-16 + 10) + y(-10 - 9) + (-60 + 4) = x(-6) + y(-19) + (-56) =-6x - 19y - 56Answer:
−6x−19y−56
Step-by-step explanation:
−8(2x)+5(2x−12)+−2(5y−2)+(−3)(3y)
Multiply −8 and 2 to get −16. Multiply −3 and 3 to get −9.
−16x+5(2x−12)−2(5y−2)−9y
Use the distributive property to multiply 5 by 2x−12.
−16x+10x−60−2(5y−2)−9y
Combine −16x and 10x to get −6x.
−6x−60−2(5y−2)−9y
Use the distributive property to multiply −2 by 5y−2.
−6x−60−10y+4−9y
Add −60 and 4 to get −56.
−6x−56−10y−9y
Combine −10y and −9y to get −19y.
−6x−56−19y

silvia compro la misma licuadora que daniela, que costaba $355.5, pero como abonó con tarjeta de credito, le recargaron un 16%, ¿cuanto pago silvia?
Answer:
Costo final= $412.38
Step-by-step explanation:
Dada la siguiente información:
Costo inicial= $355.5
Recargo de la tarjeta= 16% = 0.16
Para calcular el costo final que debe pagar Silvia, debemos usar la siguiente información:
Costo final= costo inicial*(1 + recargo)
Costo final= 355.5*1.16
Costo final= $412.38
A road roller with a 55-inch
diameter is traveling at
3 miles per hour. How many
revolutions per minute is
the roller turning? Round
your answer to the
nearest tenth
Answer:
18.34times
Step-by-step explanation:
the explanation is given in the pictures...
The road roller is turning at the rate of [tex]18.3rev/minute[/tex]
To get our answer, first note that
[tex]speed=\dfrac{distance}{time}[/tex]
since the distance travelled by the road roller can be gotten by
[tex]distance= circumference\times revolutions[/tex]
our speed formula can be expressed as
[tex]speed=\dfrac{circumference\times revolutions}{time}[/tex]
making the number of revolutions the subject of the formula, we get
[tex]revolutions=\dfrac{speed \times time}{circumference}[/tex]
carrying out the following substitutions
[tex]speed=3miles/hour=\frac{3\times63360}{60}inches/minute=3168inches/minute\\time=1minute\\circumference=2\times3.14\times\frac{55}{2}=172.7inches[/tex]
we can now calculate the number of revolutions
[tex]revolutions=\dfrac{speed\times time}{circumference}\\\\=\dfrac{3168\times 1}{172.7}\approx18.3rev/minute\text{ (to the nearest tenth)}\\\\[/tex]

find p(-1) p(1) if p(x) = X2+1
Answer:
p(- 1) = 2 and p(1) = 2
Step-by-step explanation:
Substitute x = - 1 and x = 1 into p(x), that is
p(- 1) = (- 1)² + 1 = 1 + 1 = 2
p(1) = 1² + 1 = 1 + 1 = 2

Which number is a solution for the
8.
inequality below?
3n< 18
What 8?
There is no 8 in the problem.
The answer is not a specific value for n.
3n < 18
Divide both sides by 3.
3n/3 < 18/3
n < 6
ANSWER: n < 6
What does the answer mean?
It means that n must be less than 6 to make the original inequality a true statement.

A right rectangular prism has a volume of
[tex] {6x}^{3} - {3x}^{2} - 45x[/tex]
What are expressions for the length, width, and height?
Answer:
3x, 2x + 5, and x - 3
Step-by-step explanation:
Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.
Our equation is:
6x³ - 3x² - 45x
First, we can factor out an x:
x (6x² - 3x - 45)
From here, we can see that by factoring out a 3:
3x (2x² - x - 15)
Now, after completing the square and factoring:
3x (2x + 5) (x - 3)
These are our three expressions.
