Answer:
80, 75
Step-by-step explanation:
[tex]\sqrt{x}[/tex] < 9
x < 9²
x < 81
Thus, 8 is lesser than 81. 80 and 75 are the only numbers lesser than 81 so they are the answer.
write an equation of the line that passes through the given points (-6,3) (0,4)
Answer:
y=1/6x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-3)/(0-(-6))
m=1/(0+6)
m=1/6
y-y1=m(x-x1)
y-3=1/6(x-(-6)(
y-3=1/6(x+6)
y=1/6x+6/6+3
y=1/6x+1+3
y=1/6x+4
What property of operations can be used to justify that the two expressions in this equation are equivalent? 6x^2 +4x=4x + 6x^2
Answer:
Commutative
Step-by-step explanation:
There are four basic property of operations to solve an algebraic expressions. They are associative, commutative, distributive and identity.
The expression given is : [tex]$6x^2 + 4x=4x+6x^2$[/tex]
So the given algebraic expression is a commutative property of operations. The commutative property states that when any two numbers are added in an expression the sum of the numbers are the same regardless of the order of the numbers that are added.
Thus the sum of the above expression will be same in which ever order the numbers are added.

The data shows the speed, in miles per hour, of motorists on a stretch of
road.
42, 35, 44, 31, 47, 41, 36, 34, 39, 18, 37, 32, 37, 33, 43, 41, 44, 47, 46
18 miles per hour is an outlier.
0 47 miles per hour is an outlier.
The outlier decreases the mean speed.
The outlier decreases the median speed.
Answer:
18 miles per hour is an outlier
the outlier decreases the mean speed
Step-by-step explanation:
the low number of 18 is way different from the other numbers being in the 30's and 40's
this 18 will bring the mean of all the numbers own because it is a smaller number.

Martha sells custom painted square canvases. She determined that the amount of tissue paper she'll need to wrap each canvas can be represented by
y= x^2 + 2x + 1, where y is the total square inches of tissue paper and x is the side length of the canvas in inches. Write and solve an equation to determine the side length of the canvas is Martha needs 49 square inches of tissue paper.
Given:
The equation is
[tex]y=x^2+2x+1[/tex]
where y is the total square inches of tissue paper and x is the side length of the canvas in inches.
To find:
The side length of the canvas is Martha needs 49 square inches of tissue paper.
Solution:
We have,
[tex]y=x^2+2x+1[/tex]
Putting y=49, we get
[tex]49=x^2+2x+1[/tex]
[tex]0=x^2+2x+1-49[/tex]
[tex]0=x^2+2x-48[/tex]
Splitting the middle term, we get
[tex]0=x^2+8x-6x-48[/tex]
[tex]0=x(x+8)-6(x+8)[/tex]
[tex]0=(x+8)(x-6)[/tex]
Using zero product property, we get
[tex]x+8=0[/tex] and [tex]x-6=0[/tex]
[tex]x=-8[/tex] and [tex]x=6[/tex]
Side length cannot be negative. So, only possible value of x is 6.
Therefore, Martha needs 6 inches side length of the canvas for 49 square inches of tissue paper.

Maria sells painting in a art gallery. She earns $375 each week plus a commission of 2.5% of her swelled. What is the minimum amount of sales she must have this week to earn at lease $500.
Answer:
5000.00
Step-by Step
500.00-375.00 = 125.00
5000 x 2.5% = 125.00
375.00 + 125.00 = 500.00

solve the quadratic y = −x^2 + 4x + 1 with steps plz!
Answer:
x = -0.24 or 3.73
Step-by-step explanation:
[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex] (There's supposed to be a ± between '-b' and the square root)
[tex]x^{2}[/tex] + 4x + 1 ( [tex]ax^{2} + bx + c[/tex] )
a = -1 ( there's no number before [tex]x^{2}[/tex] so its 1 )
b = 4
c = 1
Substitute into the quadratic equation.
[tex]\frac{-4 + \sqrt{4^{2} -4x1x-1 } }{2x-1}[/tex] ( the [tex]x[/tex] is just the multiplication sign )
= [tex]\frac{-4 + \sqrt{{16} +4 } }{-2}[/tex]
[tex]\frac{-4 + \sqrt{{20} } }{-2}[/tex] = -0.24 [OR] [tex]\frac{-4 - \sqrt{{20} } }{-2}[/tex] = 3.73

x=??
y=??
Answer:
x = 55
y = 45
Step-by-step explanation:
In similar triangles, the ratio between similar sides are the same. So,
AB/ED = BC/EF = AC/DF
Substitute values that they give
6/15 = 18/y = 22/x
Solve 6/15 = 18/y by cross-multiplying
6y = 15*18 = 324
Divide both sides by 6
y= 45
Solve 6/15 = 22/x by cross-multiplying.
6x = 22*15 = 330
Divide both sides by 6.
x = 55
Because there is some dispute between the answers, let's check the ratios.
6/15 = 18/45 = 22/55
0.4 = 0.4 = 0.4
True, x = 55 and y=45
since triangle abc~ def
their sides will be proportional
AB/de=ac/df
6/15=22/x
doing crisscrossed multiplication
6x=22×15
x=22×15/6=55
again
AB/de=BC/EF
6/15=18/y
doing crisscrossed multiplication
6y=15×18
y=15×18/6=15×3=45

Drag numbers to show which one is closer to -1 and -1/4 on the number line
Answer:
-0.82 is closest to -1, and -0.28 is closest to -1/4
Step-by-step explanation:
you can start by converting all of them to a fraction or decimal:
-0.28 = -28/100 = -7/25 = -14/50
-0.82 = -82/100 = -41/50
-1/5 = -10/50
-4/5 = -40/50
-1 = -50/50
-1/4 = -12.5/50
what are common prime factor of 77 and 242?
Answer:
2 times 11 times 3511
Step-by-step explanation:
i kinda dont know what your asking but i tried
The common prime factor of the numbers 77 and 242? will be 11.
What is a prime factor?A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,
Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,
77 / 11 = 7
242 / 11 = 22
Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.

The measure of H=90°, the measure of G=80° and FG=75 feet. Find the length of HF to the nearest tenth of a foot
Answer:
The length of HF is 73.9 feet.
Step-by-step explanation:
Let the length of HF be represented by x. So that applying the appropriate trigonometric function to the triangle FGH, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Where θ is the angle given in the triangle = [tex]80^{o}[/tex].
Then,
Sin 80 = [tex]\frac{x}{75}[/tex]
⇒ x = Sin 80 x 75
= 0.9848 x 75
= 73.86
x = 73.9
Thus, the length of HF is 73.9 feet.
