Answer &
Step-by-step explanation:
area = length(width) = x(x) = x²
180 = x²
x² - 180 (quadratic equation)
Solve:
✓180 = ✓36✓5 = 6✓5 ≈ 13.42 ft = x
Answer:
[tex]x=6\sqrt{5}[/tex]
Step-by-step explanation:
1) A = s²
180 ft² = x²
180 = x²
x = x² -180
x²-180 =0
11) x² - 180 = 0
x² =180
x=[tex]\sqrt{36.5}[/tex]
x=[tex]6\sqrt{5}[/tex]

Answer:
(2x +1)/(4x^2) . . . . except x=0, -1
Step-by-step explanation:
Addition of fractions works in the usual way:
a/b +c/d = (ad +bc)/(bd)
Division of fractions works in the usual way:
(a/b)/(c/d) = (ad)/(bc)

[tex]\dfrac{\left(\dfrac{1}{2x}+\dfrac{1}{2x+2}\right)}{\left(\dfrac{2x}{x+1}\right)}=\dfrac{1}{2}\cdot\dfrac{\left(\dfrac{1}{x}+\dfrac{1}{x+1}\right)}{\left(\dfrac{2x}{x+1}\right)}=\dfrac{1}{2}\cdot\dfrac{\left(\dfrac{2x+1}{x(x+1)}\right)}{\left(\dfrac{2x^2}{x(x+1)}\right)}\\\\=\boxed{\dfrac{2x+1}{4x^2}}[/tex]
The expression is undefined for any denominator equal to zero: x=0 or x=-1.
find the value (s) of the variables (s) in each parallelogram.
Answer:
y = 4
x = 12
Step-by-step explanation:
Because the lines in the parallelogram are intersecting perpendicularly, each line is equal to the opposite line.
For example,
6y + 1 = 4y + 9
and
2x - 5 = x + 7
So, now we just solve both of those equations.
We'll start with the first one :)
6y + 1 = 4y + 9
6y + 1 - 4y = 4y + 9 = 4y
2y + 1 = 9
2y + 1 - 1 = 9 - 1
2y = 8
y = 4
now onto the second equation :)
2x - 5 = x + 7
2x - 5 - x = x + 7 - x
x - 5 = 7
x - 5 + 5 = 7 + 5
x = 12

Answer:
x>8
Step-by-step explanation:
you first subtract 13 from both sides resulting in -2x<-16. Then you divide -2 on both sides and when you divide a negative on both sides you have to change the sign, -16/-2=8 so x>8.

Answer: 6 feet by 3 feet
Step-by-step explanation:
The box cannot be congruent (meaning the same size) but has to be similar. Similar means same shape but either larger or smaller by a scaled amount. In this case, the garden has to be smaller. We just need to find a scale factor that works for both 12 and 6. The only possible answer that works is 6 feet by 3 feet. This would mean the original garden would be scaled down by half.
12/2= 6
6/2= 3

Step-by-step explanation:
What is the slope of the equation: y = - 5x -6
What is the y-intercept of the equation: y = 2x
Answer:
Step-by-step explanation:
y = mx +b
Here, m is slope and b is y-intercept
1) y = -5x - 6
Slope = -5
y-intercept = -6
2) y = 2x
Slope = 2
y-intercept = 0

Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptune is one less than 3 times the number of moons of Pluto. Write and interpret a simplified expression that represents the number of moons of Neptune (I’m just asking to answer because I didn’t see any right ones when I was scrolling through them)
Answer:
neptune = 6m+2
Step-by-step explanation:
mars has 'm' moons
pluto has one more than twice that of mars, = 2m+1
neptune is one less than thrice of pluto
= 3(2m+1) -1
= 6m+3 -1
= 6m+2
The angle of elevation from a kicker's foot on the football field to the top of the goal post is 17 degrees. If he is standing 131 feet from the base of the goal post, how tall is the goal post?
Answer:
The goal post is 40.05 feet tall.
Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.
You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in
Sin
Cos
Tan
So you need to use tan.
Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:
[tex]Opp = Tan * adj
So simply plug these values in:
[tex]Opp =131 * tan(17) = 40.05
So the goal post is 40.05 feet tall

El Señor Carlos Villa quién Pide al Banco Azteca un crédito de $110000 sobre una tasa del 10% al año su cantidad a pagar será de
Responder:
121 000
Explicación paso a paso:
Dado que :
Monto del crédito = 110.000; este es el monto principal, P del préstamo
Tasa de interés = 10% = 10/100 = 0.1
Usando la relación para determinar el monto a pagar al final del año:
A = P (1 + rt)
A = monto final
A = 110 000 (1 + 0,1 * 1)
A = 11 000 (1 + 0,1)
A = 110 000 (1,1)
A = 121 000
La cantidad a pagar al final del año = 121.000

A. 6 units
B. 12 units
C. 15 units
D. 25 units
This is a similar triangle. Please find the missing length. (?)
Answer:
RQ = 10
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal;
Thus, we have it that;
QP/RQ = BC/AB
12/RQ = 36/30
RQ = 12 * 30/36 = 10

Step-by-step explanation:
On a certain hot summer's day, 310 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $581.75 How many children and how many adults swam at the public pool that day?
Answer:
Children: 51
Adults: 259
Step-by-step explanation:
Children = c Adults = a
$1.25 c + $2.00 a = $581.75
$1.25 c + $2.00 (310 - c) = $581.75
Multiply: $2.00 * 310 to get $620
Multiply: $2.00 * - c to get - $2.00 c
$1.25 c + $620 - $2.00 c = $581.75
Subtract both sides by $620
-$0.75 c = -$38.25
Divide both sides by -0.75
c = 51We now know there are 51 children.
Overall, there are 310 people so we subtract:
310 - 51 = 259
This means:
a = 259To check our answer:
51 * 1.25 = 63.75
259 * 2.00 = 518
518 + 63.75 = $581.75
