Answer: [tex]3\sqrt{3[/tex]
Step-by-step explanation: use pythagorean theorem to solve this. which is a^2 + b^2 = c^2
lets say b=3 and c=6. plug this into the equation. (6)^2 - (3)^2 + = 36 - 9 which is 27 = c^2. to get c from c^2, square root the c^2 value
the square root of 27 is [tex]3\sqrt{3[/tex] in simplest radical form

⚠️⚠️Please help⚠️⚠️ Pip and Ali share S785 in the ratio Pip:Ali = 4:1.
Work out Pip's share.
==========================================================
Work Shown:
x = Ali's share
4x = Pip's share, because it is four times bigger due to the ratio 4:1
x+4x = 5x = total amount of money = 785
5x = 785
x = 785/5
x = 157 dollars is Ali's share
4x = 4*157 = 628 dollars is Pip's share
Note that 157+628 = 785 to help confirm the answer.

The slope of the line is 0. It passes through the point (-3,4). Identify two other points on the line. Justify you answer
Answer:
Two other points: (2, 4) (6, 4)
Step-by-step explanation:
A line with a slope = 0 is a horizontal line [with a y-intercept of (0, b)], given by the linear equation, y = 4. This means that the y-coordinate will always equal to 4, regardless of its corresponding x-coordinate. Basically, we could choose any x-coordinate to pair with the y-coordinate of 4.
I chose the ordered pairs, (2, 4) and (6, 4).
Attached is a screenshot of the graphed linear equation, y = 4.

Area of circle A
[tex]\pi \times {r}^{2} = area \: of \: a \: circle \\ \pi = 3.14 \\ 3.14 \times {8}^{2} \\ 3.14 \times 64 = 200.96 \: {cm}^{2} [/tex]
Area of circle B
[tex]\pi\times 4 (because \: radius \: is \: the \: half \: of \: diameter) \\ 3.14 \times 4 square = 50.24\: {cm}^{2} [/tex]
How many times larger is the area of circle A than circle B
[tex]200.96 \div 50.24 = 4[/tex]
therefore circle A is 4 times larger than circle B in accordance with its area

[tex] = 94 \times \frac{1}{4} [/tex]
= 23.5 (Ans)
Answer:
25% of 94 is 23.5
Step-by-step explanation:
step 1: Convert the problem to an equation using the percentage formula: P% * X = Y.
step 2: take your percent then turn it into a decimal like 10% is 0.10
step 3: then multiply your decimal by your whole number like 0.10 * 65 to get your answer

15w^4 v^5 / 3w^6 v^5
Answer:
[tex]\frac{{5}}{w^{2}}[/tex]
Step-by-step explanation:
We begin with [tex]\frac{15w^{4}v^{5}}{3w^{6}v^{5}}[/tex].
Firstly, as with simplifying fractions we can simplify the numbers. 15 is divisible by 3, so this becomes [tex]\frac{5w^{4}v^{5}}{w^{6}v^{5}}[/tex].
To simplify indices (aka exponents or powers), we must subtract the power on the denominator from the matching one on the numerator, and then use that number as the power in the numerator. In this case, 4-6 and 5-5, which becomes -2 and 0.
So now we have [tex]\frac{5w^{-2}v^{0}}{1}[/tex].
For a negative power, we switch it into the other half (numerator to denominator) and take away the negative sign, leaving [tex]\frac{5v^{0}}{1w^{2}}[/tex].
We can remove the [tex]v^{0}[/tex] in the numerator as it just multiplies the numerator by one, and remove the 1 in the denominator for the same reason.
This leaves us with [tex]\frac{5}{w^{2}}[/tex].

First, notice that (a + 1/a)2 = 42 = 16. But also, (a + 1/a)2 = a2 + 2a(1/a) + 1/a2 = a2 + 2 + 1/a2 = a2 + 1/a2 + 2
So a2 + 1/a2 + 2 = 16, so a2 + 1/a2 = 14.
Now, do that again...
(a2 + 1/a2)2 = 142 = 196, but also (a2 + 1/a2)2 = a4 + 2(a2)(1/a2) + 1/a4 = a4 + 2 + 1/a4 = a4 + 1/a4 + 2
So a4 + 1/a4 + 2 = 196, so a4 + 1/a4 = 194
You can see the pattern... E.g., a8 + 1/a8 = 1942 - 2, etc.

Write the equation using the graph In slope-intercept form
Answer:
y=(2/3x)+2
Step-by-step explanation:
Selected Points: (3,4) & (-3,0)
Slope (m) = (y2-y1) / (x2-x1)
m=(4-0) / [3-(-3)]
m=4/(3+3)
m=4/6
m=2/3
Point Slope Form: y-y1=m(x-x1)
y-4=(2/3)(x-3)
y-4=(2/3x)-2
y=(2/3x)+2

5/3y=-(x-5) the slope intercept
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
[tex]\frac{5}{3}[/tex] y = - (x - 5) ← distribute parenthesis
[tex]\frac{5}{3}[/tex] y = - x + 5 ( multiply through by 3 to clear the fraction )
5y = - 3x + 15 ( divide terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x + 3 ← in slope- intercept form
