Answer:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes

The perimeter of a face of a cube is 16 mm. What is its volume?
64 mm 3
4096 mm 3
512 mm 3
128 mm 3
Answer:
The volume of a cube is s cubed (s being any edge of the cube.) You divide the perimeter by 4 to get the length of one edge. 16:4= 4. Then you cube 4.4•4•4= 64. So the answer is 64 mm cubed.

Each figure below is made up of congruent
trapezoids. Find the area of the figure.
Answer:
the area of trapizoid is 54 and all togather will be 108
Answer:
108 cm^2
Step-by-step explanation:
The formula for calculating the area of a trapezoid is (a+b)*h/2, a and b being the bases and h being the height.
Since the height of the figure is 12 cm, the height of each trapezoid is 12/2 = 6 cm because the trapezoids are congruent.
With this information we can calculate each trapezoid's area: (base 1 + base 2)*height / 2 = (6+12)*6/2 = 18*3 = 54 cm^2.
We know the area of one trapezoid is 54 cm^2, so two trapezoids would have an area of 108 cm^2 (the figure is composed of two trapezoids).

write the algebraic expression that matches each graph.
20 POINTS + BRAINLEIST
Answer:
Step-by-step explanation:
The (positive) slope of the line whose domain is (-infinity, -1) is
m = rise/run = 1/1, or m = 1. The (negative) slope of the other line segment is
m = rise/run = -1/1, or m = -1.
Let's now find the equation of the line with m = 1. Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2. Then the equation is y = x + 2 on the domain (-infinity, -1).
Now find the equation of the line with negative slope:
y = -x + b; the y-intercept is immediately evident from the graph as b = 0.
Then the desired eequation is y = -x on the domain (-1, infinity).

Answer:
Im not sure but I think its C
Answer:
C
Step-by-step explanation:
Because it is the only one that goes down into a negitive slope, A increases, B is constant (Stays the same), and D increases. so C is also your only option
find the value of h that makes the equation true
Answer:
it should be 13! h+13

2. The control variable is what stays the same so the material the acid is poured on must be the same as different materials have different reactions to acids.
3. The independent variable is what's being changed and in this experiment the mass of the ball is changed each time
4. The independent variable is what's being changed and in this experiment the temperature is different in each cup.

Write the algebraic expression that matches each graph
Answer:
1. y= |x| -15
2. y = -|x| +3
Step-by-step explanation
.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.

Latisha earns $5 an hour painting her neighbor's fence.
Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)
Part B: List three ordered pairs to show the values of the two variables. (3 points)
Part C: Write an equation to represent the relationship between the two variables. (3 points)
Please I really need help!
Answer:
Part A: Variables : M = money, H = number of hours. So the number of hours(H) is independent and the money(M) is a dependent variable.
Part B: Ordered pairs : (0 Hours, 0$), ( 1 Hour, 5$), (2 Hours, 10$)
Part C: H*5 = M
Step-by-step explanation:
Part A: The money is dependent on the number of hours because per hour she paints the fence, she gets 5$. So the hour changes, and because of this, Latisha gets 5$ more.
Part B: The ordered pairs are in the form (number of hours, money).
Part C: H*5 = M. A few examples of this are 1x5=5, 2x5=10, 10x5=50.

A. The more he chooses to pay off each month, the higher total interest he will pay.
B. The quicker he pays off the credit card, the more interest he will pay.
C. The more he chooses to pay off each month, the less total interest he will pay.
D. The amount he chooses to pay each month will not affect the total interest he pays.
letter B is the answer
Step-by-step explanation:
she needs some credit
The correct conclusion from the table shows C. The more he chooses to pay off each month, the less total interest he will pay.
How is interest determined?The interest amount is calculated based on the outstanding balance.
When a cardholder makes more monthly payments, the interest amount reduces because of the reduction in the outstanding balance.
