Answer:
x = 15
Step-by-step explanation:
Angles in a triangle add up to equal 180
Hence, 3x + 5x + 4x = 180
( Note that we've just created an equation that we can use to solve for x)
We now solve for x using the equation created
3x + 5x + 4x = 180
Combine like terms
12x = 180
Divide both sides by 12
x = 15
Answer:
x = 15
Step-by-step explanation:
The sum of the angles of a triangle is 180
3x+4x+5x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15

Which equation correctly shows that (x^2)^4=x^8?
Answers
Answer: The answer is D
because x^2^4 power is x^8 and x^2*x^2*x^2*x^2 which is 2+2+2+2 which is x^8
Step-by-step explanation:
it is not C because it would be 4(c^2) which is 4x^2
it is not A because (x^2)(x^4) is 2+4 which is 6 so that means it would be x^6
The exponent equation correctly shows that [tex](x^{2} )^{4}=x^{8}[/tex] is
[tex](x^{2} )^{4}=x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] = [tex]x[/tex] × [tex]x[/tex] ×[tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] = [tex]x^{8}[/tex]
Option (D) is correct
What is an exponent law?Exponents are also called powers or indices. The exponent rules explain how to solve various equations that as you might expect have exponents in them. They are several different kinds of exponent equations.
Given exponent equation
[tex](x^{2} )^{4}=x^{8}[/tex]
[tex](x^{2} )^{4}=x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex]
If the bases are same, then the powers should be added from an exponent law. It is called as product of powers rule.
[tex](a^{m} )^{n} = a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{m+n}[/tex]
By adding the power, we get
2+2+2+2 = 8
∴ [tex](x^{2} )^{4} =x^{2+2+2+2} = x^{8}[/tex]
Hence, Option (D) is correct
The exponent equation correctly shows that [tex](x^{2} )^{4}=x^{8}[/tex] is
[tex](x^{2} )^{4}=x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] × [tex]x^{2}[/tex] = [tex]x[/tex] × [tex]x[/tex] ×[tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] × [tex]x[/tex] = [tex]x^{8}[/tex]

Answer:
? = A) 4
Step-by-step explanation:
If we notice line FG and QR are similar.
FG = 24 and QR = 8. The relationship between the the two sides is that FG is 3 times more than QR ---> 8 x 3 = 24.
This relationship is true for the rest of the triangles since they are stated to be similar:
FG = 3(QR)
24 = 3(8)
EG = 3(6)
18 = 3(6)
Finding PQ:
EF = 3(PQ)
12 = 3(?)
? = 4
Therefore, the unknown side is 4.

Step-by-step explanation:
The distributive property applies.
(f·g)(x) = f(x)·g(x) = (3x +1)(x^2 -6) = 3x(x^2 -6) +1(x^2 -6)
(f·g)(x) = 3x^3 -18x +x^2 -6 . . . . . eliminate parentheses

Three times one number added to five times another number is 54. The second number is two less than the first. Use a system of equations to find the numbers
Answers
Answer:
8 and 6
Step-by-step explanation:
If you use x for the first number, and y for the second, you get equations of 3x+5y=54 and x-2=y.
You can substitute the second equation into the first one to solve it. This gives 3x+5(x-2)=54.
The brackets can be expanded to 3x+5x-10=54. Collecting like terms makes it 8x-10=54.
Next, we add 10 to both sides. This gives 8x=64.
From there, we isolate the x by dividing both sides by 8, giving x=8.
To work out the second number, we can sub 8 for x in either equation (I'm using the second one as it's simpler).
This comes to y=8-2, therefore y=6.

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year. Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. Which system of equations can be used to find s, the number of pages in each issue of the sports magazine, and t, the number of pages in each issue of the technology magazine?
A. t = s - 18
10t = 12s + 32
B. s = t - 18
12s = 10t + 32
C. s = t - 18
10s = 12t + 32
D. t = s - 18
12t = 10s + 32
Answers
Answer:
[tex]\text{B .}\\\begin{cases}s=t-18, \\12s=10t+32\end{cases}[/tex]
Step-by-step explanation:
The each issue of the sports magazine, [tex]s[/tex], has 18 fewer pages than each issue of the technology magazine, [tex]t[/tex], we have equation [tex]s=t-18[/tex]. This eliminates answer choices A and D.
The second equation can be written from the fact that the total number of pages in all the sports magazines, [tex]12s[/tex], is 32 more than the total number of pages in all the technology magazines, [tex]10t[/tex]. Thus, we have equation [tex]12s=10t+32[/tex], eliminating answer choice C and leaving answer choice [tex]\boxed{\text{B .}\\\begin{cases}s=t-18, \\12s=10t+32\end{cases}}[/tex]

In a study conducted at a large long-term care facility, two data collectors examined 56 pressure ulcers on 40 different subjects. The examinations were independently performed on the same day.

What can be determined from this finding?

Answer:
Interrater reliability between the two data collectors was high
Step-by-step explanation:
Explanation-
Interrater reliability is the consistency of observations between two or more observers. An Agreement of 54 out of 56 scores would indicate a high level of interrater reliability. The data collection method was appropriate for pressure ulcer risk assessment. The risk assessments did not have to be done by both evaluators at the same time.X + 24 + 4 + 63 = 180

If x is a positive integer, for how many different values of x is StartRoot StartFraction 48 Over x EndFraction EndRoot a whole number? 2 3 6 10
Answers
Answer:
3
Step-by-step explanation:
According To the Question,
Given that, 'x' is a positive integer . And We have to find the number of different values of 'x', So that the value of [tex]\sqrt{\frac{48}{x} }[/tex] is a Whole number.Then First, we have to find those values of 'x' for which the given fraction is a square.
We Know, All the factors of 48 are {1,2,3,4,6,8,12,16,24,48} .
Now, From the above factors, only (3,12 & 48) can give us a square number.
Therefore,
If x=3, Then [tex]\sqrt{\frac{48}{3} } = \sqrt{16}[/tex] ⇒ 4If, x=12, Then [tex]\sqrt{\frac{48}{12} } = \sqrt{4}[/tex] ⇒ 2If, x=48, Then [tex]\sqrt{\frac{48}{48} } = \sqrt{1}[/tex] ⇒ 1Thus, There are 3 whole numbers (3,12,48).
