Answer:
The dirt is [tex]\frac{2}{3}ft[/tex] deep
Step-by-step explanation:
The raised garden bed has width, w=6ft.
The length of the garden bed is;
l=8ft
The height, h is how deep, the dirt is.
The volume of dirt the garden bed contains is 32 cubic feet.
The volume is given by the formula;
[tex]Volume=l\times w\times h[/tex]
We substitute the given values and solve for x.
[tex]32=8\times 6\times h[/tex]
[tex]32=48h[/tex]
[tex]h=\frac{32}{48}[/tex]
[tex]h=\frac{2}{3}ft[/tex]
The dirt is [tex]\frac{2}{3}ft[/tex] deep

12 in. ²
a = bh
a = 2 x 6
a = 12 in. ²
Answer:
12 in. ^2
Step-by-step explanation:
The area of a rectangle can be found by using the formula legnth x width.
Here the legnth is 2 in. and the width is 6 in.
6 x 2 = 12
Whenever you find the area, unit of measurement is ^2, thus resulting in the answer 12 in. ^2

Give the first four terms of the geometric sequence for which a1 = -7 and r= -4
Answer:
- 7, 28, - 112, 448
Step-by-step explanation:
To obtain the next term in a geometric sequence multiply the previous term by r
Given
a₁ = - 7 and r = - 4, then
a₂ = - 7 × - 4 = 28
a₃ = 28 × - 4 = - 112
a₄ = - 112 × - 4 = 448

An Isosceles triangle has single measures 55,55,and 70. The side across from the 70 angle is 10 inches long. How long are the other sides?
Answer:
8.717 both the sides
Step-by-step explanation:
Given:
Let ABC be the given triangle with
angle A= 55
angle B=55
angle C= 70
side across angle C, c= 10 inches
side across angle B, b =?
aide across angle A,a=?
Now using the law of sin to find a and b:
a/sinA=c/sinC
a= (c/sinC)(sinA)
Putting the values:
a= (10/sin70)(sin55)
a= 8.717
As the given triangle is isosceles so side a=b
hence a=b= 8.717 inches !

which is not a proportion???
The answer is C. C is not a proportion.
Hope this helps!
Answer:
C
Step-by-step explanation:
By definition a proportion should be equal to each other and can be multiplied by the same number on the numerator and the denominator to make the second fraction.
[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]
[tex]\frac{x_1}{y_1}*\frac{z}{z}=\frac{x_2}{y_2}[/tex]
A
[tex]\frac{3}{7}*\frac{3}{3}=\frac{9}{21}[/tex]
So it is a proportion.
B
[tex]\frac{24}{56}/\frac{8}{8}=\frac{3}{7}[/tex]
So it is a proportion.
C
[tex]\frac{3}{7}*\frac{3}{4}=\frac{9}{28}[/tex]
So it is not a proportion.
D
[tex]\frac{3}{7}*\frac{4}{4}=\frac{12}{28}[/tex]
A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4 unit. How many 1/4 unit cubes does it take to fill the prism?
Answer:
128
Step-by-step explanation:
Method A.
The volume of the prism is 2 cubic units.
Each cube has side length of 1/4 unit.
The volume of each cube is (1/4)^3 cubic unit.
The volume of each cube is 1/64 cubic unit.
To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.
(2 cubic units)/(1/64 cubic units) =
= 2/(1/64)
= 2 * 64
= 128
Method B.
Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128
He right answer is 128

The slope of the line passing through the points (-2, 6) and (4, 6) is
A) 0
B) no slope
C) 2
Your answer ish c. 2
A slope is also known as the gradient of a line. The correct option is B.
What is Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
The slope of the line that is passing through (-2, 6) and (4, 6) can be calculated as,
Slope = (6-6)/(-2-4) = 0/(-6)
Hence, there exists no slope between the two of the given points.

Find the point, M, that divides segment AB into a ratio of 2:3 if A is at (0, 15) and B is at (20, 0).
What is segment ab? is there a picture that is supposed to go with it?
Answer: The required co-ordinates of point M are (8, 9).
Step-by-step explanation: Given that the point M divides segment AB into a ratio of 2 : 3, where A is at (0, 15) and B is at (20, 0).
We are to find the co-ordinates of point M.
We know that
the co-ordinates of a point that divides the line segment joining the points (a, b) and (c, d) are given by
[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).[/tex]
For the given division, (a, b) = (0, 15), (c, d) = (20, 0) and m : n = 2 : 3.
Therefore, the co-ordinates of point M are given by
[tex]\left(\dfrac{2\times20+3\times0}{2+3},\dfrac{2\times0+3\times15}{2+3}\right)\\\\\\=\left(\dfrac{40}{5},\dfrac{45}{5}\right)\\\\\\=\left(8,9).[/tex]
Thus, the required co-ordinates of point M are (8, 9).
Tina is attempting to factor the expression 10x^2-13-3. In her first step, she rewrites the expression as 10x^2-10x-3x-3. Which of the following statements in true about Tina's work?
ANSWER
B. The two middle coefficients add to the correct number but do not multiply to the correct number.
EXPLANATION
The given quadratic trinomial that Tina tries to factor is
[tex]10 {x}^{2} - 13x - 3[/tex]
Comparing to
[tex]a{x}^{2} + bx + c[/tex]
we have a=10, b=-13 and c=-3
ac=-3×10=-30
We split the middle term so that their sum is -13.
Tina use
-10,-3
to get
-10x-3x
The sum is -13x alright but the product is not -30.
B is correct.

Jerry drove 10 miles in half the time it took Marcy to drive 10 miles. If jerry average speed was r miles per hour what was Marcy average speed in miles per hour
Answer:
0.5r
Step-by-step explanation:
If Jerry took half the time Macy did then that means Macy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Macy goes half as slow and takes twice as long to get there.
The average speed of Marcy in miles per hour is 0.5r.
If Jerry took half the time Marcy did then that means Marcy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Marcy goes half as slow and takes twice as long to get there.

(5,6), (9,1) slope intercept form
Answer:
y = (-5/4)x + 12.25
Step-by-step explanation:
Slope intercept form:
y = mx + b
Slope form:
m = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (9 , 1)
(x₂ , y₂) = (5 , 6)
Plug in the corresponding numbers to the corresponding variables.
m = (6 - 1)/(5 - 9)
Simplify.
m = (5)/(-4)
Your slope is -5/4
Plug in -5/4 for m in the slope-intercept form equation, and use a point to solve for b. For example, we will use (9, 1):
y = mx + b
y = (-5/4)x + b
(1) = (-5/4)(9) + b
Simplify.
1 = (-11.25) + b
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Add 11.25 to both sides.
1 + (11.25) = -11.25 (+11.25) + b
1 + 11.25 = b
b = 12.25
your y-intercept is 12.25
Plug in the corresponding numbers to the corresponding variables.
y = mx + b
m = -5/4
b = 12.25
y = (-5/4)x + 12.25 is your answer.

3w - 4z = 8 what is w
Final answer:
To find w from the equation 3w - 4z = 8, add 4z to both sides, and then divide by 3 to isolate w, giving w = (4z + 8) / 3.
Explanation:
The equation 3w - 4z = 8 is a linear equation in two variables (w and z). To find w in terms of z, you need to isolate w on one side of the equation. Here is the process step by step:
Add 4z to both sides of the equation: 3w - 4z + 4z = 8 + 4z.
Simplify the equation: 3w = 4z + 8.
Divide every term by 3 to solve for w: w = (4z + 8) / 3.
So, w is equal to (4z + 8) / 3 when isolated from the given equation.
