The figure below shows a rectangular prism and a cube:
A rectangular prism and a cube are drawn side by side. The length of the rectangle prism is 5 inches, the width is 4 over 5 inch, and its height is 1 and 3 over 5 inches. The cube has a side length of 1 over 5 inch.
How many such cubes are required to completely pack the prism without any gap or overlap?
Answer:
Calculate the volume of each shape.
Volume of rectangle = 6 x 5/6 x 1 2/6 = 6 2/3 cubic inches.
Volume of cube = 1/6 x 1/6 x 1/6 = 1/216 cubic inch.
Now divide the volume of the rectangle by the volume of the cube:
6 2/3 / 1/216 = 1440
It will take 1.440 cubes to fill the rectangle.

[tex]\mathrm{Divide\:both\:sides\:by\:}12[/tex]
[tex]\frac{12x}{12}=\frac{24}{12}[/tex]
[tex]\mathrm{Simplify}[/tex]
x =2
Answer:
x = 2
Step-by-step explanation:
1) Reorder the terms
3x + 5 = 29 - 9x
3x + 5 = -9x + 29
2) Subtract 5 from both sides
3x + 5 - 5 = -9x + 29 - 5
3x = -9x + 24
3) Add 9x to both sides
3x + 9x = -9x + 9x + 24
12x = 24
4) Divide both sides by the same factor
12x/12 = 24/12
x = 2

Answer:
Answer is F:
y = 2x + 4
Step-by-step explanation:
The slope-intercept form of a line is given by
y = mx + b
where m is the slope of the line and b is the y-intercept ie the y value where the line crosses the y axis for x = 0
In the line y = 2x + 4, the slope of the line is 2
If 2 lines are parallel to each other, they must have the same slope
Therefore the line passing through (-1,2) must have an equation of the form y = 2x + b.
There are only 2 choices that fit this equation, F and H
If we substitute the values of x=-1 into the F equation for testing we get
y = 2(-1) + 4 = -2 +4 = 2 which is the correct value for y for the point(-1,2)
The other choice y = 2x + 3 does not work because substituting for x we get
y = 2(-1) + 3 = -2 + 3 = 1 which is not the value of y for the point (-1,2)
The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
А. 12 inches
B. 15 inches
C. 21 inches
D.40 inches
We know that,
☆ Perimeter of a Rectangle = 2 (length + width)
Hence,
42 = 2 (length + 6)
or, 42/2 = length + 6
or, 21 = length + 6
or, length = 21 - 6
or, length = 15
The length is 15 inches.
Therefore, the correct answer is option (B) 15 inches.I will give brainliest! Make sure to tell me each question label! In a triple batch of a spice mix, there are 6 teaspoons of garlic powder and 15 teaspoons of salt. Answer the following questions about the mix.7a, 7b, 7c, 7d

3.Solve: 12 = -4h + 7 +11h
Which of the following would be an appropriate first step to take in solving for "h"?
Group of answer choices
adding 7 to both sides
adding 12 to both sides
combining (-4h) and (11h)
multiplying both side by 4
Answer:
$3.21
Step-by-step explanation:
Answer:
1: $3.21.
2: 50x+120=300
3: h=5/7/ first step would be to adding 7 to both sides.
Step-by-step explanation:
for the 3rd:
you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.Evaluate the expression. Write your answer as a fraction in simplest form.
-3 3/4 x 5/6 - 2 1/3=
The expression in simplest form is 7 7/24.
What is a Fraction?A fraction is a number that can be written in the form of p/q, where q≠0.
The expression given is -3(3/4) * (5/6) - 2(1/3)
-15/4 * 5/6 * (-7/3)
= (25*7) / (4*6)
= 175 /24
= 7 7/24
Therefore, the expression in simplest form is 7 7/24.
