Step-by-step explanation:
plug in x for the missing number and solve
Answer:
4. 12 (3.5) -15 = 27
5. -18 (445.5) -¾ = 24
Step-by-step explanation:
4. 12? -15 = 27
12? = 42
? = 3.5
5. -18? -¾ = 24
-18? = 24 + 3/4
-18? = 96/4 + 3/4
-18? = 99/4
? = 891/2 or 445.5

What is the factorization of 216x12 – 64?
(6x3 – 4)(36x6 + 24x3 + 16)
(6x3 – 4)(36x9 + 24x3 + 16)
(6x4 – 4)(36x8 + 24x4 + 16)
(6x4 – 4)(36x12 + 24x4 + 16)
9514 1404 393
Answer:
(c) (6x^4 – 4)(36x^8 + 24x^4 + 16)
Step-by-step explanation:
The correct factoring can be found by looking at the first exponent in the second set of parentheses.
The factorization of ...
(a^3 -b^3)
is ...
(a -b)(a^2 +ab +b^2)
__
Here, you have a=6x^4 and b=4, so the first term in the second parentheses is ...
a^2 = (6x^4)^2 = 6^2·x^(4·2) = 36x^8 . . . . matches the 3rd choice

y=2x+9 y=4x-9 Solve the system of equations.
Answer:
Your solution is (9, 27) or x = 9, y = 27
Step-by-step explanation:
y = 2x + 9
y = 4x - 9
We can see that both of these equations equal y, so we can set them equal to each other.
2x + 9 = 4x - 9
Add 9 to both sides.
2x + 18 = 4x
Subtract 2x from both sides.
18 = 2x
Divide both sides by 2.
9 = x
Now we want to find y. To do this, plug x = 9 back into one of the original equations.
y = 2(9) + 9
Multiply.
y = 18 + 9
Add.
y = 27
Your solution is (9, 27)
Check your answer by plugging x = 9 and y = 27 back into the original equations.
y = 2x + 9
27 = 2(9) + 9
27 = 18 + 9
27 = 27
y = 4x - 9
27 = 4(9) - 9
27 = 36 - 9
27 = 27
Your answer is correct.
Hope this helps!
Answer:
x=9,y=27
Step-by-step explanation:
y=2x+9,........equation 1
y=4x-9..........equation 2
from equation 1 and 2
we get
2x+9=4x-9
9+9=4x-2x
x=18/2=9
substituting value of x in equation 1
y=2×9+9=18+9=27
Find the circumference and area of each circle to the nearest tenth. Use 3.14 for pi. 1.) radius = 1.7 2.) radius = 14 ft 3.) 9 in
Answer:
Step-by-step explanation:
Circumference of a circle = 2πr
Area of circle = πr²
Here, r = radius of the circle
1). For radius = 1.7 units
Circumference = 2π(1.7)
= 2(3.14)(1.7)
= 10.676
≈ 10.7 units
Area of the circle = π(1.7)²
= 3.14(1.7)²
= 9.0746
= 9.1 units²
2). For radius = 14 ft
Circumference of the circle = 2π(14)
= 28(3.14)
= 87.92
≈ 87.9 ft
Area of the circle = πr²
= 3.14(14)²
= 615.44
≈ 615.4 ft²
3). For radius = 9 in.
Circumference = 2π(9)
= 18π
= 56.52
≈ 56.5 in
Area of the circle = π(9)²
= 81π
= 254.34 in²
≈ 254.3 in²

The distance in miles that some students live from school is show in the histogram which stamen about the data in the histogram is true
Answer:
D). The distribution of the data is symmetrical, so the mean and median are within the "2.1-3 mile" category.
Step-by-step explanation:
The last statement i.e. 'The distribution..."2.1-3 mile" category' correctly asserts a true claim regarding the data provided in the given histogram. It aptly states that the dissemination of the data is uniform(2, 4, 5, 4, 2(no. of students) live between the distance of 0.1 to 5 miles from the school) and this causes both the mean, as well as, the median of the distribution to fall in the category between '2.1 to 3 mile.' Thus, option D is the correct answer.

Explain why a rotation of 270 Degress clockwise will result in the same transformation as a rotation of 90 degress counterclockwise.
Answer:
Step-by-step explanation:
b/c they end up in the same place but take different ways of getting there... 90 + 270 adds up to a full circle of 390 so b/c one goes in the positive direction and one goes in the negative, the both get to the same location, :)

Answer:
y = 27
Step-by-step explanation:
The altitude of a right triangle creates two triangles that are each similar to each other and to the larger right triangle. This means corresponding sides are proportional.
If we write the proportion for the legs, we get ...
(long leg) / (short leg) = y/18 = 18/12
Multiplying by 18 gives us ...
y = 18(18/12)
y = 27
_____
Additional comment
The leg/leg proportion above gave rise to the relation ...
altitude² = (left hypotenuse segment)×(right hypotenuse segment)
That is, the altitude is the geometric mean of the two hypotenuse segments it touches. 18 = √(12y)
__
There are two other "geometric mean" relationships in this triangle.
The upper left side is the geometric mean of the left hypotenuse segment and the whole hypotenuse (the two segments it touches at the bottom).The upper right side is the geometric mean of the right hypotenuse segment and the whole hypotenuse (the two segments it touches at the bottom).Each of these relationships is ultimately derived from the fact that all of the triangles are similar. You really only need to remember that these triangles are all similar and corresponding sides of similar triangles are proportional. (In some cases, it can be a bit of a shortcut if you remember the geometric mean relations.)

In ΔSTU, t = 96 cm, u = 98 cm and ∠S=46°. Find the length of s, to the nearest centimeter.
The length of s to the nearest centimetre is 76 cm
What are Triangles?
Triangles are polygon with three sides.
Therefore, the triangle STU have the following properties.
t = 96 cmu = 98 cm∠S = 46°s = ?Let's find s using cosine law. Therefore,
s² = t² + u² - 2tu cos STherefore,
s² = 96² + 98² - 2 × 96 × 98 cos 46°
s² = 9216 + 9604 - 18816 × 0.69465837045
s² = 18820 - 13070.6918986
s² = 5749.3082
s = √5749.3082
s = 75.8241927092
