Answer:
4/5
Step-by-step explanation:
If we are given this value as a percent we can simply turn that percentage into a fraction. 80% would be 8/10 but since the question wants the fraction in simplest form we can achieve this by dividing both the numerator and denominator by 2. This would give us 4/5, which if we divide the numerator by the denominator we get 0.80 which is 80%. Therefore, the fraction of those surveyed that had at least one brother or sister is 4/5

15 points
[tex] \sqrt{(3 + 2) ^{2} } [/tex]
Step-by-step explanation:
Given :-
(√3+√2)²√{(3+2)²}And we need to simplify the given numbers . We can use a identity in 1st Question as ,
[tex]\implies (a+b)^2=a^2+b^2+2ab[/tex]
Simplifying first :-
[tex]\implies (\sqrt3+\sqrt2)^2\\\\\implies (\sqrt3)^2+(\sqrt2)^2+2.\sqrt3.\sqrt2 \\\\\implies 3+2+2\sqrt6=\boxed{\red{5+\sqrt6 }}[/tex]
Simplifying second :-

What is the range of 39,41,5,43,26,7,43,24,41
Answer:
38
Step-by-step explanation:
The range of a data set is the smallest number subtracted from the largest number.
[tex]39,41,5,43,26,7,43,24,41[/tex]
In this data set, the largest number is 43 and the smallest number is 5.
[tex]43-5=38[/tex]
Therefore, 38 is the range of this data set.

Step-by-step explanation:
the triangle is right angle.
at right angle it makes 90°. therefore;
(3d+1)°+(6d+8)°=90°
3d+1°+6d+8°=90°
9d+9°=90°.
9d=90°-9°
9d=81°
d=81/9
d=9°

Please factor using the x method
( please do not answer if you don't know how to do it )
Answer:
[tex]2(x - 5) ( 9x - 2)[/tex]
Step-by-step explanation:
((2•3^2x^2) - 94x) + 20
Pull like factors :
18x^2 - 94x + 20 = 2 • (9x^2 - 47x + 10)
Factor
9x^2 - 47x + 10
The first term is, 9x^2 its coefficient is 9.
The middle term is, -47x its coefficient is -47.
The last term, "the constant", is +10
Step-1: Multiply the coefficient of the first term by the constant 9 • 10 = 90
Step-2: Find two factors of 90 whose sum equals the coefficient of the middle term, which is -47.
-90 + -1 = -91
-45 + -2 = -47
Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -45 and -2
9x^2 - 45x - 2x - 10
Step-4: Add up the first 2 terms, pulling out like factors :
9x • (x-5)
Add up the last 2 terms, pulling out common factors :
2 • (x-5)
Step-5: Add up the four terms of step 4 :
(9x-2) • (x-5)
Which is the desired factorization
thus the answer is
[tex]2(x - 5) ( 9x - 2)[/tex]
Answer:
Solution given:
18x²-94x+20
taking common
2(9x²-47x+10)
doing middle term factorization
90=45*2
2(9x²-45x-2x+10)
2(9x(x-5)-2(x-5))
2(9x-2)(x-5)
2(x-5)(9x-2)

Approximate the distance between (0, -5) and (4, 1) to the nearest tenth, if necessary.
Answer:
7.7
Step-by-step explanation:
To solve this question we must use Pythagoras (a²+b²=c²) Let those two dots be A and B respectively.Imagine a line is drawn that pases through both dots,
Imagine that the line given is the hypotenuse (the longest side of a right-angled triangle) of a right-angled triangle and the other sides as a line from A going to the right, and a line from B going downwards, making the final vertexes for the triangle at coordinates: 0,-5 4,1 and 4,-5 (the vertex we made). now we find the lengths for the sides: 4 and 6 so we use these to plug them into pythagoras's equation:
4²+6²=c²
24+36=c²
√60=c
c=7.74....
But all we need is until the tenths so the answer is 7.7 (as the hundredths digit, 4, rounds down)
the sum of 5 distinct prime numbers is an even number. which of the following is one of the 5 numbers in the sum?
Answer:
2
Step-by-step explanation:
One of them has to be 2. Two odd numbers added together make an even number. So you have two pairs of odd prime numbers and 2 must be the last one. If it is not then the sum will be odd.
Here's an example
3 + 5 + 7 + 11 = 26 which is even. If the next prime is odd, the whole sum will be odd.
26 + 17 = 43
However if the 5th number is two, then the sum of the 5 primes will be even.
26 + 2 = 28
