Answers
Answer:
total marbles = 15 + 12 = 27
blue marbles = 12
probability of blue marble = 12/27 simplifies to 4/9
Question:
Can anyone help me been stuck for a while.
Answer:
[tex]\frac{4}{9}[/tex]
Step-by-step explanation:
The bag has 15 white marbles,
and 12 blue marbles.
Add the totals together, and you would get:
27.
turn that into a fraction:
[tex]\frac{12}{27}[/tex]
then simplify:
Find the GCD (or HCF) of numerator and denominator
GCD of 12 and 27 is 3
Divide both the numerator and denominator by the GCD
12 ÷ 3
27 ÷ 3
Reduced fraction:
[tex]\frac{4}{9}[/tex]
Therefore, [tex]\frac{12}{27}[/tex] simplified to lowest terms is:
[tex]\frac{4}{9}[/tex]
Therefore, your answer would be: [tex]\frac{4}{9}[/tex]
Vada places a box of toys and a box of books together. The box of toys has a length of 5 feet, a width of 3 feet, and a height of 2 feet. The box of books has a length of 6 feet, a width of 4 feet, and a height of 2 feet. What is the combined volume of the boxes?
Answers
Answer:
78 ft cubed
Step-by-step explanation:
First calculate the volume of the toys...
5 x 3 x 2 = 30
Now the book boxes...
6 x 4 x 2 = 48
30 + 48 = 78
The combined volume should be 78 feet cubed! hope this helps!!!
Answer:
78 ft³
Step-by-step explanation:
Volume of a rectangular prism = length × width × height
Toy Box
length = 5 ftwidth = 3 ftheight = 2ft⇒ volume = 5 × 3 × 2 = 30 ft³
Book Box
length = 6 ftwidth = 4 ftheight = 2 ft⇒ volume = 6 × 4 × 2 = 48 ft³
Total combined volume = 30 + 48 = 78 ft³

ObtusestraightrightacuteThere is a pair of parallel sides in the following shape. 4 4 6 What is the area of the shape?
Answers
============================================================
Explanation:
It might help to rotate the figure so the parallel sides are horizontal. This is optional.
The parallel bases are [tex]b_1 = 6[/tex] and [tex]b_2 = 4[/tex] in either order.
The height is h = 4 which is always perpendicular to both bases.
Plug these values into the trapezoid area formula.
[tex]A = \frac{h(b_1 + b_2)}{2}\\\\A = \frac{4(6+4)}{2}\\\\A = \frac{4(10)}{2}\\\\A = \frac{40}{2}\\\\A = 20\\\\[/tex]
The area of the trapezoid is 20 square units.
-----------
Another pathway is to break the trapezoid into a rectangle up top and a triangle down below.
The rectangle is 4 by 4 with area 4*4 = 16
The triangle has a base of 6-4 = 2 and height of 4, so its area is base*height/2 = 2*4/2 = 8/2 = 4
Overall the total area is rectangle+triangle = 16+4 = 20 square units.

Determine formula of the nth term 2, 6, 12 20 30,42
Answers
Check the forward differences of the sequence.
If [tex]\{a_n\} = \{2,6,12,20,30,42,\ldots\}[/tex], then let [tex]\{b_n\}[/tex] be the sequence of first-order differences of [tex]\{a_n\}[/tex]. That is, for n ≥ 1,
[tex]b_n = a_{n+1} - a_n[/tex]
so that [tex]\{b_n\} = \{4, 6, 8, 10, 12, \ldots\}[/tex].
Let [tex]\{c_n\}[/tex] be the sequence of differences of [tex]\{b_n\}[/tex],
[tex]c_n = b_{n+1} - b_n[/tex]
and we see that this is a constant sequence, [tex]\{c_n\} = \{2, 2, 2, 2, \ldots\}[/tex]. In other words, [tex]\{b_n\}[/tex] is an arithmetic sequence with common difference between terms of 2. That is,
[tex]2 = b_{n+1} - b_n \implies b_{n+1} = b_n + 2[/tex]
and we can solve for [tex]b_n[/tex] in terms of [tex]b_1=4[/tex]:
[tex]b_{n+1} = b_n + 2[/tex]
[tex]b_{n+1} = (b_{n-1}+2) + 2 = b_{n-1} + 2\times2[/tex]
[tex]b_{n+1} = (b_{n-2}+2) + 2\times2 = b_{n-2} + 3\times2[/tex]
and so on down to
[tex]b_{n+1} = b_1 + 2n \implies b_{n+1} = 2n + 4 \implies b_n = 2(n-1)+4 = 2(n + 1)[/tex]
We solve for [tex]a_n[/tex] in the same way.
[tex]2(n+1) = a_{n+1} - a_n \implies a_{n+1} = a_n + 2(n + 1)[/tex]
Then
[tex]a_{n+1} = (a_{n-1} + 2n) + 2(n+1) \\ ~~~~~~~= a_{n-1} + 2 ((n+1) + n)[/tex]
[tex]a_{n+1} = (a_{n-2} + 2(n-1)) + 2((n+1)+n) \\ ~~~~~~~ = a_{n-2} + 2 ((n+1) + n + (n-1))[/tex]
[tex]a_{n+1} = (a_{n-3} + 2(n-2)) + 2((n+1)+n+(n-1)) \\ ~~~~~~~= a_{n-3} + 2 ((n+1) + n + (n-1) + (n-2))[/tex]
and so on down to
[tex]a_{n+1} = a_1 + 2 \displaystyle \sum_{k=2}^{n+1} k = 2 + 2 \times \frac{n(n+3)}2[/tex]
[tex]\implies a_{n+1} = n^2 + 3n + 2 \implies \boxed{a_n = n^2 + n}[/tex]

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of cases ordered by Camp Copeland be = 20 cases
Let the number of eggs in each case = 12 eggs
So , the equation will be
The number of eggs in 20 cases A = 20 x number of eggs in each case
Substituting the values in the equation , we get
The number of eggs in 20 cases A = 20 x 12
The number of eggs in 20 cases A = 240 eggs
Therefore , the value of A is 240 eggs
Hence , the number of eggs is 240 eggs

Answers
Answer:
Step-by-step explanation:
Answer:
C^2 = 95 ft is the length of the hypotenuse.
Step-by-step explanation:
To get the hypotenuse, apply the Pythagorean theorem.
The formula is a^2+b^2=c^2, where a and b are the leg lenths and c is the length of the hypotenuse. This is referred to as the Pythagorean theorem.
We know what a and b are, so lets utilize the Pythagorean theorem
.
a^2 + b^2 = c^2 - This is the Pythagorean theorem formula.
76^2 + 57^2 = C^2 - Fill in the equation with a= 76 and b = 57^2.
5776 + 3249 = c^2
9025 = c^2 - C^2 is found by adding A^2 and B^2.
square root of c^2 = square root of 9025 - Take the square root of both sides of the equation.
C = 95 ft - Simplify
C^2 = 95 ft is the length of the hypotenuse. Brainliest? :D
