Answer:
= 6(4 + 5)
Step-by-step explanation:
GCF = The greatest common factor, example: GCF of 12 and 16 = 12 is divisible by all of these numbers. The factors for 16 are 1, 2, 4, 8, 16. The two numbers (12 and 16) share common factors (1, 2, 4). The greatest of these is 4 and that is the greatest common factor.
Distributive property = allows us to multiply the number by a group of numbers, which are added together. The distributive property is given by: a(b+c) = ab + ac
The Greatest Common Factor of 24 and 30 is 6 because it is the largest number they have together (24 = 6*4 and 30 = 6*5)
24 divided by 6 = 4
30 divided by 6 = 5
This fits B the most: 6(4 + 5)

Cecilia bought 187.6 pounds of crushed limestone in a total of eight bags. if all the bags were identical, what was the weight of each?
The weight of each bag is 23.25 pounds.
For given question,
Cecilia bought 187.6 pounds of crushed limestone in a total of eight bags.
If all the bags were identical, we need to find the weight of each bag.
Let 'm' be the weight of each bag.
As Cecilia bought 187.6 pounds of crushed limestone in a total of eight bags and all the bags were identical, we get an expression.
8 × m = 187.6
now we solve above expression to find the value of m i.e., to find the weight of each bag.
⇒ 8 × m = 187.6
⇒ m = 187.6 / 8
⇒ m = 23.25 pounds
Therefore, the weight of each bag is 23.25 pounds.

You start a savings account with $200 and save $30 each month. Let f(n) be the amount in the account before the nth month. How much money will you have invested at one year?
The money you will have invested at one year is $560
What are linear equations?Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
How much money will you have invested at one year?The given parameters are:
Initial = $200
Rate = $30
Let the number of months be n
So, we have
f(n) = Initial + Rate * n
This gives
f(n) = 200 + 30n
There are 12 months in a year
So, we have:
f(12) = 200 + 30 * 12
Evaluate
f(12) = 560
Hence, the money you will have invested at one year is $560

-12=6+2/3y pls helpppp
Answer:
Y= (-27)
Step-by-step explanation:
Well, I am assuming your just looking for Y. So what I did was you'd want to get rid of the fraction first. I multiplied 3 to all the numbers. so -12(3) = 6(3) + 2y since the bottom 3 from the fraction cancelled out with the (3). so now it would be -36=18+2y. -54/2=2y/2 which leads to -27. So I think Y= -27.
A square pyramid has a volume of 4320 cubic inches. What is the volume of this pyramid in cubic feet?
The volume of the given square pyramid in cubic feet is 2.5 cubic feet.
Given that, a square pyramid has a volume of 4320 cubic inches.
We need to find the volume of this pyramid in cubic feet.
What is the volume of a square pyramid?The volume of a square pyramid is one-third of the product of the area of the base and the height of the pyramid. Thus, volume = (1/3) × (Base Area) × (Height).
To convert from cubic inches to cubic feet, divide your cubic inches figure by 1728.
Now, 4320/1728 = 2.5 cubic feet
Therefore, the volume of the given square pyramid in cubic feet is 2.5 cubic feet.

Answer:
q = 20
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.

subtract 2 from both sides
5q = 100
100 / 5 = 20
5q / 5 = q

We get the translation rule as (x-4, y+5) for triangle ABC.
We are given a triangle:
ABC where
A = (3, -1)
B = (7, -5)
C = (-2, -2)
And, we are also given the translation of the triangle as A'B'C'
where
A' = (-1, 4)
B' = (3, 0)
C' = (-6, 3)
We need to tell the translation rule for it,
For the x coordinate, we can see that:
- 1 - 3 = - 4
3 - 7 = - 4
- 6 - (-2) = -4
So, the rule for x coordinate will be:
x - 4
Now for y coordinate:
4 - (-1) = 5
0 - (-5) = 5
3 - (-2) = 5
So, the rule for y coordinate will be:
y + 5
Translation rule then becomes:
(x-4, y+5)
Therefore, we get the translation rule as (x-4, y+5) for triangle ABC.

Find the lengths of ABC and BD explain pls
Answer: The length of AB =4 units
The length of BD = 2.4 units.
Step-by-step explanation:
Given data,
AD = 3.2 unit
BC = 3 unit
CD = 1.8 units
Find : AB =? units
BD=? units
We can use the formula of Pythagorean theorem,
Define Pythagorean theorem :
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.
Hypotenuse2 = Perpendicular2 + Base2
c2 = a2 + b2
Where “a” is the perpendicular,
“b” is the base,
“c” is the hypotenuse.
Let be a ΔABC,
[tex](AB)^{2} = (BC)^{2} +(AC)^{2}[/tex]
From the above formula now determined the value of AB and BD,
Firstly , find the value of BD
In ΔBDC, by applying Pythagorean theorem,
[tex](BC)^{2} = (BD)^{2} + (DC)^{2}[/tex] (Eq - 1)
Substitute BC and CD values in equation 1,
BC = 3 units and CD = 1.8 units
So,
We can write,
[tex]3^{2} = (BD)^{2} +(1.8)^{2}[/tex]
9 = [tex](BD)^{2}[/tex] + 3.24
[tex](BD)^{2}[/tex] = 9 - 3.24
[tex](BD)^{2}[/tex] = 5.76
[tex]BD = \sqrt{5.76}[/tex]
BD = 2.4 units (Eq - 2)
Now find the value of AB,
In ΔABD, by applying Pythagorean theorem,
[tex](AB)^{2} = (AD)^{2} +(BD)^{2}[/tex] (Eq - 3)
Substitute AD and BD values in equation 3,
AD = 3.2 units and BD = 3 units
So,
We can write,
[tex](AB)^{2} = (3.2)^{2} + 3^{2}[/tex]
[tex](AB)^{2}[/tex] = 10.24 + 5.76
[tex](AB)^{2}[/tex] = 16
AB = [tex]\sqrt{16}[/tex]
AB = 4 units
Therefore,
The length of AB =4 units
The length of BD = 2.4 units.

Step 2: Remove the decimal places by multiplication.
Step 3: Reduce the fraction.
Step 4: Simplify the remaining fraction to a mixed number fraction if possible.
Given,
The smallest flowering plant is the flowering aquatic duckweed found in Australia.
And it is 0.0236 inch long and 0.0129 inch wide.
Here we need to write these dimensions as fractions in simplest form.
Rewrite the decimal number as a fraction with 1 in the denominator
So,
=> 0.0236/1 and 0.0129/1
Now, Multiply to remove 4 decimal places. Here, you multiply top and bottom by 10⁴ = 10000.
Then we get,
=> 236/10000 and 129/10000
Now, reduce the fraction by dividing both numerator and denominator by GCF = 4,
=> 59/2500
But the fraction 129/10000 is not reducible.

[tex]\begin{aligned}\textsf{b)} \quad m \angle 1 & =\boxed{6^{\circ}}\\ m \angle 2 & =\boxed{84^{\circ}}\end{aligned}[/tex]
Step-by-step explanation:
Part (a)From inspection of the given diagram, the sum of the two angles is 90° (indicated by the right angle sign):
[tex]\implies m \angle 1+m \angle 2=90^{\circ}[/tex]
[tex]\implies (x - 8)^{\circ} + (6x)^{\circ} = 90^{\circ}[/tex]
[tex]\implies x-8+6x=90[/tex]
[tex]\textsf{Equation}: \quad \boxed{x-8+6x=90}[/tex]
Part (b)To find the measure of each angle, solve the equation for x:
[tex]\implies x-8+6x=90[/tex]
[tex]\implies x+6x-8=90[/tex]
[tex]\implies 7x-8=90[/tex]
[tex]\implies 7x-8+8=90+8[/tex]
[tex]\implies 7x=98[/tex]
[tex]\implies \dfrac{7x}{7}=\dfrac{98}{7}[/tex]
[tex]\implies x=14[/tex]
Substitute the found value of x into the expression for each angle:
[tex]\implies m \angle 1=(x-8)^{\circ}[/tex]
[tex]\implies m \angle 1=(14-8)^{\circ}[/tex]
[tex]\implies m \angle 1=\boxed{6^{\circ}}[/tex]
[tex]\implies m \angle 2=(6x)^{\circ}[/tex]
[tex]\implies m \angle 2=(6 \cdot 14)^{\circ}[/tex]
[tex]\implies m \angle 2=\boxed{84^{\circ}}[/tex]
