155.5-5.5∙20.7 help me with this
Answer:
41.65
Step-by-step explanation:
First do 5.5*20.7 because of PEMDAS or GERMDAS which is basically saying the order of how to solve expressions/equations
5.5*20.7=113.85
Then subtract 113.85 from 155.5
155.5-113.85=41.65

If $a = 4$, $b = 2$, and $c = -5$, then what is the value of $\sqrt[3]{4a^4b^5} + \dfrac{a - c}{(b+c)^2}$?
Answer is not 13 or 31.
[tex]\sqrt[3]{4 a^4 b^5} = \sqrt[3]{4 \times 4^4 \times 2^5} = \sqrt[3]{(4\times 2)^5} = \sqrt[3]{(2^2\times2)^5} = \sqrt[3]{(2^3)^5} = \sqrt[3]{2^{15}} = \sqrt[3]{(2^5)^3} = 2^5 = 32[/tex]
[tex]\dfrac{a-c}{(b+c)^2} = \dfrac{4-(-5)}{(2+(-5))^2} = \dfrac{4+5}{(2-5)^2} = \dfrac9{(-3)^2} = \dfrac99 = 1[/tex]
Then the expression evaluates to 32 + 1 = 33.
The value of the expression
[tex]$\sqrt[3]{4a^4b^5} + \dfrac{a - c}{(b+c)^2}$[/tex]
is 33 when $a = 4$, $b = 2$, and $c = -5$.
How did we get the values?Let's substitute the given values into the expression and calculate the result:
Given:
$a = 4$
$b = 2$
$c = -5$
Substituting the values:
[tex]$\sqrt[3]{4a^4b^5} + \dfrac{a - c}{(b+c)^2} = \sqrt[3]{4(4)^4(2)^5} + \dfrac{4 - (-5)}{(2+(-5))^2}$[/tex]
Calculating the values within the cube root:
[tex]$\sqrt[3]{4(4)^4(2)^5} = \sqrt[3]{4 \cdot 256 \cdot 32} = \sqrt[3]{32768} = 32$[/tex]
Calculating the values within the fraction:
[tex]$\dfrac{4 - (-5)}{(2+(-5))^2} = \dfrac{4 + 5}{(-3)^2} = \dfrac{9}{9} = 1$[/tex]
Now we can substitute the calculated values back into the expression:
[tex]$\sqrt[3]{4a^4b^5} + \dfrac{a - c}{(b+c)^2} = 32 + 1 = 33$[/tex]
Therefore, the value of
[tex]\sqrt[3]{4a^4b^5} + \frac{a - c}{(b+c)^2} \: is \: 33 \: when \: a = 4, \: b = 2, and \: c = -5[/tex]

Question 5 of 10
Which algebraic expression is a product with a factor of 5?
A. 5(y-6)
B. -2y+ 5+ 3
O C. 5y - 7
D. 3y + 1
For this case we have the following expression:
[tex]5(y-6)[/tex]
We observe that the number 5 is a common factor of both terms within the parenthesis.
To prove it, we can apply the distributive property.
We have then:
[tex]5y-30[/tex]
We observe then that 5 is a common factor of the given expression.
Answer:
An algebraic expression that is a product with a factor of 5 is:
A) 5 (y-6)

For n = 10 and π = 0.68, what is P(X= 3)?
Given the equation that’s uploaded below!
Please help!!!!!
Answer:
0.01296 to 5 decimal places.
Step-by-step explanation:
P(3) = 10! / 3! 7! * (0.68)^3 (1 - 0.68)^(10-3)
= 120 * (0.68)^3 * (0.32)^7
= 120 * 0.314432 * 0.00034359738
= 0.01296456
Find the variation and an equation of variation where y varies inversely as x and y= 0.4 when x= 0.8
Hi!
The words "y varies inversely as x" automatically means we can write:
[tex]y=\cfrac{k}{x}[/tex]
Note that this is a fraction because it said "inversely". If it had said "jointly" or "directly", it would have been [tex]y=kx[/tex].
Now, we plug in the given values to solve for k.
We are given:
[tex]y = 0.4[/tex]
[tex]x = 0.8[/tex]
Plug those in and we have:
[tex]0.4=\cfrac{k}{0.8}[/tex]
Multiply both sides by [tex]0.8[/tex]:
[tex]0.32=k[/tex]
Now, with the value of [tex]k[/tex] solved for, we put it back into the original equation, and that's your answer:
[tex]y=\cfrac{0.32}{x}[/tex]

486,732 is the number in which the digit 6 have a value that is 10 times as great as the value of the digit 6 in 283,691. Option B is correct.
To find the number in which the digit 6 has a value that is 10 times as great as the value of the digit 6 in 283,691, we need to compare the place values of the digit 6 in both numbers.
In the number 283,691:
The 6 is in the hundreds place.
Now let us multiply this place with 10.
100×10 = 1000.
Find the number in which the digit is in 1000 place.
In the number 486732, the 6 is in 1000 place.
Hence, Option B is correct. 486,732 is the number in which the digit 6 have a value that is 10 times as great as the value of the digit 6 in 283,691.

If an object is thrown upward from a 100-foot-high platform with an initial velocity of 64 feet
per second, then its height in feet is given by h(t) = -16t2 + 64t + 100 where t is time in
seconds. What is the maximum height reached by the object?
Answer:
164 ft
Step-by-step explanation:
The TIME of maximum height (this is a dome shaped parabola)
will be given by t = -b/2a = - 64 / (2)(-16) = 2 sec
Putting in t = 2 into the equation will give the max height
-16 (2^2) + 64(2) + 100 = max = 164 ft

For the given angle measure, find the measure of a supplementary angle and the measure of a complementary angle. 27
Answer:
A complementary angle is 63 degrees and supplementary angle is 153 degrees.
Step-by-step explanation:
Complementary angle:
A complementary angle adds up to 90 degrees, so you have to subtract 27 from 90. 90-27=63
Supplementary angle:
A supplementary angle adds up to 180 degrees, so you have to subtract 27 from 180. 180-27=153

solve the one in the middle asking for f'(10)
From the definition, we have
[tex]\displaystyle f'(10) = \lim_{x\to0} \frac{f(x) - f(10)}{x - 10}[/tex]
With [tex]f(x)=\sqrt{x-1}[/tex], we get [tex]f(10)=\sqrt{10-1}=\sqrt9=3[/tex]. So the limit we want to compute is
[tex]\displaystyle f'(10) = \lim_{x\to0} \frac{\sqrt{x-1} - 3}{x - 10}[/tex]
Rationalize the numerator by multiplying by its conjugate:
[tex]\displaystyle \frac{\sqrt{x-1} - 3}{x - 10} \times \frac{\sqrt{x-1}+3}{\sqrt{x-1}+3} = \frac{\left(\sqrt{x-1}\right)^2-3^2}{(x-10)\left(\sqrt{x-1}+3\right)} = \frac{x-10}{(x-10)\left(\sqrt{x-1}+3\right)}[/tex]
x is approaching 10, which is to say x ≠ 10, so we can cancel the factors of x - 10 and remove the discontinuity.
Then we're left with
[tex]\displaystyle f'(10) = \lim_{x\to0} \frac1{\sqrt{x-1}+3} = \frac1{\sqrt{10-1}+3} = \frac1{\sqrt9+3} = \frac1{3+3} = \boxed{\frac16}[/tex]
evaluated by direct substitution, which we can do since the limand is continuous.

asap, help me with 17 and 18.
Answer:
17. 125 ft^2
18. 9.4 in^2
Step-by-step explanation:
Both 17 and 18 are similar. You split that it into pieces.
Area of Rectangle/Square: Area = Length * Width
Area of a Triangle: Area = 1/2 * Base * Height.
17.
Area Rectangle:
Area = Length * Width
Area = 10 ft * 6 ft = 60 ft^2
Area Triangle:
Area = 1/2 * Base * Height
Area = 1/2 * 10 ft * 13 ft = 65 ft^2
Total Area = 60 ft^2 + 65 ft^2 = 125 ft^2
18.
Area Rectangle:
Area = Length * Width
Area = 2.7 in * 2 in = 5.4 in^2
Area Triangle:
Area = 1/2 * Base * Height
Area = 1/2 * 2 in * 4.4 ft = 4.4 ft^2
Total Area = 5.4 ft^2 + 4.4 ft^2 = 9.4 ft^2
