7 Question Find the value of x.
Answer:
x = 15
Step-by-step explanation:
45/3 = 15
Solve for x. Enter the solutions from least to greatest.
(x + 7)² - 49 = 0
lesser x =
greater x =
Answer:
Lesser x = -14
Greater x = 0
Step-by-step explanation:
Given equation:
[tex]\sf (x+7)^2-49=0[/tex]
Add 49 to both sides:
[tex]\implies \sf (x+7)^2-49+49=0+49[/tex]
[tex]\implies \sf (x+7)^2=49[/tex]
Square root both sides:
[tex]\implies \sf \sqrt{(x+7)^2}=\sqrt{49}[/tex]
[tex]\implies \sf x+7=\pm7[/tex]
Solve for x:
[tex]\implies \sf x+7=7 \implies x=0[/tex]
[tex]\implies \sf x+7=-7 \implies x=-14[/tex]
As -14 < 0
Lesser x = -14Greater x = 0what is the exponent of 24?
Answer:

Answer:
13.9
Step-by-step explanation:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Find the difference between coordinates:
(x2 - x1) = (-5 - 0) = -5
(y2 - y1) = (-3 - 10) = -13
Square the results and sum them up:
(-5)^2 + (-13)^2 = 25 + 169 = 194
Now Find the square root and that's your result:
Exact solution: √194
Approximate solution: 13.9284

Hope this helps :)
the answer to the expression 8:4(5+2) is approximately 0.2857.
To solve the expression 8:4(5+2), we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
First, we simplify the expression inside the parentheses: 5 + 2 = 7.
Next, we perform the multiplication: 4 * 7 = 28.
Finally, we perform the division: 8 ÷ 28 = 0.2857 (rounded to four decimal places).
So, the answer to the expression 8:4(5+2) is approximately 0.2857. Remember that it's crucial to follow the order of operations to arrive at the correct result in mathematical expressions.

Does anybody know this?The two pentagons shown are similar if the area of the smaller pentagon is 232m^3 find the area of the larger pentagon
Answer:
(a) 362.5 m²
Step-by-step explanation:
The ratio of areas is proportional to the square of the ratio of side lengths.
__
scale factorlarger/smaller = (35 cm)/(28 cm) = 5/4
areaThe larger area is the square of this scale factor times the smaller area.
(5/4)²(232 m²) = 362.5 m²
_____
Additional comment
We assume the units are intended to match. It is impossible for a pentagon with a side length of 28 cm to have an area of 232 m². A regular pentagon with a side length of 28 cm will have an area of about 0.1349 m².

en una optica se ofrece la siguiente promoción: se descuenta de la compra de anteojos un porcentaje idéntico a la edad correspondiente del cliente, es decir, si el cliente tiene 23 años, el descuento se le aplica de un 23%. El abuelo de Andrés dice: esos anteojos de $40.000 me costarían tan solo $4.000. ¿Qué edad tiene el abuelo de Andrés?
We will see that the percentage in which the price decreases is 90%, thus the age is 90 years.
How old is Andrés?
We know that the percentage in which the price decreases is equal to the age of Andrés.
We can write:
P = $4,000 = $40,000*(1 - k)
Where k is the percentage in decimal form.
Solving for k:
k = ($40,000 - $4,000)/$40,000 = 0.9
To obtain the percentage, we multiply by 100%.
0.9*100% = 90%
We conclude that Andrés is 90 years old.

A motor boat traveled 18 miles down a river in 2 hours but took 4.5 hours to return upstream. Find the rate of the motor boat in still water and the rate of the current.
b = speed of the boat in still water
c = speed of the current
when going Upstream, the boat is not really going "b" fast, is really going slower, is going "b - c", because the current is subtracting speed from it, likewise, when going Downstream the boat is not going "b" fast, is really going faster, is going "b + c", because the current is adding its speed to it.
now, going either way the boat travelled the same 18 miles.

The interpretations of the function values are: the cost of buying 0, 10 and 67.5 gallons of paint would be 0, 28.5 and 73.9, respectively
How to interpret the function values?The equation of the function is given as:
f(x) = 9√x
When x = 0, 10 and 67.5, we have:
f(0) = 9√0 = 0
f(10) = 9√10 = 28.5
f(67.5) = 9√67.5 = 73.9
