Step-by-step explanation:
1:5= 6 parts
54/6=9
9*1=9
9*5=45
9:45
Answer:
9kg and 45kg
Step-by-step explanation:
In fraction from 1:5 is equivalent to 1/(1+5) = 1/6 and 5/(1+5) = 5/6.
So the answer is 54 * 1/6 and 54 * 5/6.
= 9 and 45.

Answer:
40/3
Step-by-step explanation:
4x -20 = 10x -100 (Distributive Property)
4x -10x = -100 +20 (I swith the numbers so all of them are similar)
-6x= -80 (Divide -6 on both sides)
And you will get 40/3 or 13.3333..
Answer:
x = 40/3
Step-by-step explanation:
4(x-5)=10(x-10)
=> 4x - 20 = 10x - 100
=> 4x - 10x = - 100 + 20
=> -6x = -80
=> x = 80/6
=> x = 40/3

if AB= 5 what is the exact length of BD in square ABCD
Answer:
sqrt 50
Step-by-step explanation:
First of all this is a square so if AB = 5, then AD is also 5.
Let's get rid of the other triangle and only focus on triangle ABD.
Using Pythagorean theorem we are able to solve this problem.
The Pythagorean Theorem basically states that:
a^2 + b^2 = c^2
Where a and b are the legs and c is the hypotenuse, aka the thing that we are trying to solve for right now.
Substitute these numbers in: 5^2 + 5+2 = c^2
Solve: 50 = c^2
c= sqrt 50
^ and that is our answer!

The m
Write in slope intercept: slope=2/3 y-intercept =-1
Answer:
y=2/3-1.
Step-by-step explanation:
Slope intercept is the easiest out of the forms because you just plug in what is given. Here you are given 2/3 for the slope and the y-int Is -1.
The formula for slope intercept is y=mx+b
m= slope
b= y-int
And you just plug it in.
so the answer would be: y=2/3-1. Hope this helps!

What is the image of (2, 1) after a dilation by a scale factor of 4 centered at the
origin?
HELP
Answer:
The image of the point is (8, 4)
Step-by-step explanation:
If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)
Let us solve the question
∵ The point is (2, 1)
∴ x = 2 and y = 1
∵ The point dilated by a scale factor of 4 centered at the origin
∴ k = 4
→ By using the rule above multiply each coordinate of the point by 4
∵ The image of the point is (kx, ky)
∵ kx = 4 × 2
∴ kx = 8
∵ ky = 4 × 1
∴ ky = 4
∴ The image of the point is (8, 4)

Work out angle BXC.
Give a reason for each angle you work out.
Answer:
∠ BXC = 70°
Step-by-step explanation:
∠ XBC and ∠ AXY are corresponding angles and are congruent, then
∠ XBC = 55°
Since XB = XC , then Δ XBC is isosceles and the 2 base angles are congruent.
∠ BXC = 180° - (55 + 55)° ← angle sum of triangle
∠ BXC = 180° - 110° = 70°
The measure of angle BXC is 70°
What s transversal?"It is a line that passes through two lines in the same plane at two different points."
What are parallel lines?"These are the lines in the same plane that are at equal distance from each other and never meet."
What are isosceles triangle?"It is a triangle having any two sides equal in length."
For given example,
We can observe that XY and BD are parallel lines and AB is the transversal.
Here,
∠AXY = ∠XBC ..............(Corresponding angles)
⇒ ∠XBC = 55°
In figure, for ΔXBC the sides XB and XC are equal.
So, ΔXBC is an isosceles triangle.
We know, for isosceles triangle, angles opposite to equal sides are equal in measure.
⇒ ∠XBC = ∠XCB
⇒ ∠XCB = 55°
We know, the sum of all angles of the triangle is 180°.
⇒ ∠XBC + ∠XCB + ∠BXC = 180°
⇒ 55° + 55° + ∠BXC = 180°
⇒ 110° + ∠BXC = 180°
⇒ ∠BXC = 70°
Therefore, the measure of angle BXC is 70°

A number pattern was created by dividing the previous term by 3. If the starting value for the pattern was 135, which of the following shows the resulting pattern?
A.
135, 45, 30, 5...
B.
135, 45, 15, 5...
C.
135, 45, 15, 2...
D.
135, 45, 30, 25...
Answer:
B. 135, 45, 15, 5...
Step-by-step explanation:
I'll go in order from 135 using the pattern shown (tᵇ/3)
135 / 3
135 = 120 + 15
135/3 = (120/3) + (15/3)
135/3 = 40 + 5
135/3 = 45
All four answer choices show this, so no elimination yet.
45 / 3
45 = 30 + 15
45/3 = (30/3) + (15/3)
45/3 = 10 + 5
45/3 = 15
A and D show 30 as term 3, so they are out.
15 / 3
15/3 = 5
C shows 2 as term 4, so that is also out.
This leaves B as the correct answer.

If x and y vary directly, and x = 12 when
y = 4, what is the value of x when y = 1 ?
Answer:
3
Step-by-step explanation:
Answer: x = 3
Step-by-step explanation:
y for x
4 for 12
1 for ?
Cross multiply
4? = 12 x 1
4? = 12
Divide both sides by 4
? = 3
When y = 1, x = 3.

Find the measure of each numbered angle
Answer:
1. 71 degrees 2. 109 degrees 3. 90 degrees 4. 90 degrees
Step-by-step explanation:
109 + 71 = 180 (straight line)
so the other side (under) of 109 degrees is 71 degrees. That angle is the same angle as 1 because that same line (transversal) runs through both parallel lines.
The angle diagonal from 2 is 109 because it mirrors the same measurements as the one on the left. Angle 2 is the same angle as 109 degrees because it's a vertical angle. All vertical angles are equal.
Because the same line on the bottom runs through the parallel lines then the same angles apply to both on the bottom. The right one is a 90 degree angle
which makes both 3 and 4 90 degrees because 90 + 90 equals a straight line 180 degrees.

How many days will it take the comet to reach earth?
Answer:
It will take 10^3 days for the comet to reach earth.

10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
