Answer:
It is multiplication
Step-by-step explanation:
It is multiplication because when you divide 9,460,730,472,580.8 by 299,792,458 you will get 31557.6 so that means,
9,460,730,472,580.8/299,792,458 = 31557.6
so, 299,792,458 * 31557.6 = 9,460,730,472,580.8
So the answer is Multiplication by 31557.6

Answer:
y = 16/3 or 5.333333...
Step-by-step explanation:
5x - 3y = 4
→ Substitute the value of x = 4 into the expression
(5 × 4) - 3y = 4 ⇔ 20 - 3y = 4
20 - 3y = 4
→ Minus 20 from both sides to isolate -3y
-3y = -16
→ Divide both sides by 3 to isolate y
y = 16/3 or 5.333333...

Answer:
(- 2, 4 )
Step-by-step explanation:
A translation of 5 units left means subtract 5 from the original x- coordinate.
A translation of 6 units up means add 6 to the original y- coordinate.
Thus
(3, - 2 ) → (3- 5, - 2 + 6 ) → (- 2, 4 )
The coordinates of the point (3,-2), translated 5 units left and 6
units up are (-2, 4) option (D) (-2, 4) is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The point (3,-2), translated 5 units left and 6 units up.
A 5-unit left translation entails taking 5 away from the initial x-coordinate.
A translation of six units upwards entails multiplying the initial y-coordinate by six.
After applying the translation:
(3, -2) → (3- 5, - 2 + 6) → (-2, 4)
Thus, the coordinates of the point (3,-2), translated 5 units left and 6
units up are (-2, 4) option (D) (-2, 4) is correct.

BC = -2x+85 BD = 5x-48 What is the length of BC?
Answer:
-2x + 85 = 5x - 48
85 = 7x - 48

x = 19
BC = -2(19) + 85
BC = -38 + 85
therefore, BC = 47

a right angle triangle has the perimeter of 96cm. the length of its sides are in the ratio of 6:8:10. work out the area of the triangle
Answer:
384 centimeters squared.
Step-by-step explanation:
96/(6+8+10)
96/24 = 4
6×4 : 8×4 : 10×4
24:32:40
The length of its sides are in the ratio of 24:32:40
The longest side is the hypotenuse which is 40.
The area is base × height × 1/2 of a triangle.
32 × 24 × 1/2
768 × 1/2
=384
The area of the triangle is 384 cm squared.
Answer:
Area = 384 cm²
Step-by-step explanation:
Perimeter = 96 cm
Ratio = 6:8:10
So,
6x+8x+10x = 96
=> 24x = 96
Dividing both sides by 24
=> x = 4
So, The sides are
=> 24 cm
=> 32 cm
=> 40 cm
Now the area using Heron's Formula
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where s is the semi-perimeter = 48 cm, a , b and c are the sides
Area = [tex]\sqrt{48(48-24)(48-32)(48-40)}[/tex]
Area = [tex]\sqrt{48(24)(16)(8)}[/tex]
Area = [tex]\sqrt{147,456}[/tex]
Area = 384 cm²
and the answer has to be in cm squared.

Work out ( 4 × 10 6 ) × ( 2 × 10 7 ) Give your answer in standard form.
Answer:
4 * 2 = 8
10^6 * 10^7 = 10^(6 + 7) = 10^13
Answer is 8 * 10^13
So I'm pretty sure I solved a similar question before, but we always write the equation first.
So, equation:
(4 × 10^6) × (2 × 10^7)
Again, we will use the order of operations.
() - Parenthesis
^x - Exponents
×/÷ - Multiplication/Division
+/- - Addition/Subtraction
Now, solve the parenthesis. We have two parentheses, so we will solve those separately.
(4 × 10^6)= 4 × 1,000,000 = 4,000,000
(2 × 10^7)= 2 × 10,000,000 = 20,000,000
Now, multiply these two together.
4,000,000 × 20,000,000 = 80000000000000
BUT, we can simplify this. So, the real answer is:
8 × 10^13

There are 4 red marbles and 3 blue marbles in a bag. Once a marble is drawn it is not replaced. Find the probability of drawing two red marbles in a row.
Answer:
2/7
Step-by-step explanation:
4 red marbles and 3 blue marbles in a bag = 7 marbles
P(red) = red/total = 4/7
No replacement
3 red marbles and 3 blue marbles in a bag = 6 marbles
P(red) = red/total = 3/6 = 1/2

michael puts 3 beds next to each other on a piece of string to make a bracelet. each need has a width of 5/6 inches. which expression and fraction both represent the width of the three beads
Answer:
Total width = 5/2 or 2½
Step-by-step explanation:
Since we have 3 beads and each of them have a width of 5/6 inches, thus;
Total width = 3 × (5/6)
Total width = 15/6
Simplifying this since 3 is common multiple to both numerator and denominator, we have;
Total width = (15/3)/(6/3)
Total width = 5/2
Since this is an improper fraction, we need to turn it into a mixed fraction, thus;
Total width = 5/2 = 2½
Those total width is 5/2 or 2½

the top of two poles of height's 20m and 14m are connected by the wire
if the wire makes an angle 30 degree with the horizontal then length of the wire is
8m
10m
12m
Answer:
The correct option is;
10 m
Step-by-step explanation:
The parameters given are;
Height of the first pole = 20 m
Height of the second pole = 14 m
The angle the wire connected to their top makes with the horizontal = 30°
The vertical height subtended by the inclined wire, h = The difference in height between the two poles = 20 - 14 = 6 m.
Let the horizontal distance between the two poles = D
Therefore;
The horizontal length of the wire = D
From trigonometric ratios, we have;
[tex]tan(30 ^{\circ}) = \dfrac{h}{D} = \dfrac{6}{D}[/tex]
Which gives;
[tex]D = \dfrac{6}{tan(30 ^{\circ}) } = 10.39 \ m\approx 10 \ m[/tex]
The correct option is 10 m.
What is the solution to the system of equation? 2x+6y=-6 4x-3y=-12
Answer:
(-3, 0)
Step-by-step explanation:
We can solve this algebraically (substitution or elimination) or graphically.
Step 1: Multiply the first equation by -2
-4x - 12y = 12
4x - 3y = -12
Step 2: Add the 2 equations together and solve for y
-15y = 0
y = 0
Step 3: Plug y back into an original equation to get x
2x + 6(0) = -6
2x = -6
x = -3
And we have your answer!
Answer:
2x+6y=-6 ........1
4x-3y=-12 ........2
Simplify equation 1
2x + 6y = -6
Divide both sides by 2
You will get
x + 3y = -3
Make x the subject
x = - 3 - 3y
Substitute x into equation 2
4x - 3y = - 12
4(- 3 - 3y) - 3y = - 12
-12 + 12y - 3y = -12
9y = -12 + 12
9y = 0
Divide both sides by 9
y = 0
Substitute y = 0 into x = - 3 - 3y
You will get
x = - 3 - 3(0)
x = -3
Therefore x = - 3 and y = 0

Point B ∈ AC so that AB : BC = 2:1. Point D ∈ AB so that AD : DB = 3:2. Find AD : DC.
Answer:
AD : DC is 2:3
Step-by-step explanation:
The parameters given are;
Point B ∈ AC
AB : BC = 2:1
Point D ∈ AB
AD : DB = 3:2
Therefore, whereby we sum the ratios, we have;
For AC
AB = 2/(2+1)×AC = 2/3×AC
BC = 1/3×AC
For AB
AD = 3/(3+2)×AB = 3/5×AB
DB = 2/5×AB
We are required to find AD:DC
Given that AD = 3/5×AB and AB = 2/3×AC
We have;
AD = 3/5×2/3×AC = 6/15 AC
DC = DB + BC = 2/5×AB + 1/3×AC = 2/5×2/3×AC + 1/3×AC = 4/15×AC + 1/3×AC
DC = 3/5×AC
AD : DC = 6/15 AC : 3/5×AC = 2:3.
