she needs 6 boxes
Step-by-step explanation:
multiply the dimensions of the box which is 24.
multiply it by 3 because she has 3 boxes.
24 times 3 is 72
72≠128
part 2:
divide 128 by 24 which is 5.333
you cant have a third of a box so round it up to 6 .

Answer:
length(l) is 8 m
area=56^2
l*b=56^2
8*b=56^2
b=56/8
hence,
breadth {width}(b) is 7 m
hence , perimeter is

A semicircle with diameter 8 inches is connected to a triangle with a base length of 8 inches. The height of the triangle is 3 inches.
What is the area of the composite figure?
Answer:
Step-by-step explanation:
Area of the semicircle = pi * r^2 / 2
d = 8
r = d/ 2
r = 8/2 = 4 inches
Area = pi * 4^2 / 2
Area = 3.14 * 8
Area = 25.12 square inches
Area of the triangle
Area = 1/2 * b * h
b = 8
h = 3
Area = 1/2 * 8 * 3
Area = 12 square inches
Total area = 25.12 + 12
Total area = 37.12 square inches

Work out the nth term of the following sequence:
7, 16, 31, 52, 79
its a quadratic sequence and i worked out the second difference (6) so know its 3n² but i don't know the rest
Answer:
Step-by-step explanation:
Since it is given that it is quadratic it is of the form f(n)=an^2 + bn+c.
Since we know a few terms we can plug in to get some equations:
f(1)= a +b+c = 7
f(2)=4a+2b+c = 16
f(3)=9a+3b+c = 31
Now you've got yourself a system of three equations which I trust you can solve.
I will say that I'm not sure that this is the most efficient solution(check out the link below which might have a better solve).

anyone know if they can help me rq
We are given two equations, one of which has an isolated variable [tex]x[/tex].
That screams to me that substitution would be a prefered strategy here, compared to elimination, although both work.
That means we'll be substituting our value of [tex]x[/tex], which is given as [tex]-y+3[/tex], into the first equation, [tex]15x+31y=-3[/tex].
[tex]15x+31y=-3[/tex]
[tex]x=-y+3[/tex]
[tex]15(-y+3)+31y=-3[/tex]
[tex]-15y+45+31y=-3[/tex]
[tex]16y=-48[/tex]
[tex]y=-3[/tex]
With this value, we can plug it back into either of the two equations to solve for [tex]x[/tex], I'll be substituting it back into the second equation, since it's easier.
[tex]x=-y+3[/tex]
[tex]y=-3[/tex]
[tex]x=-(-3)+3[/tex]
[tex]x=6[/tex]
So our solution is [tex](6,-3)[/tex], and to check we can plug it back into the first equation.
[tex]15x+31y=-3[/tex]
[tex]15(6)+31(-3)=-3[/tex]
[tex]90-93=-3[/tex]
Which is true, so our solution is correct.
Hope this helps!

Step-by-step explanation:
[tex]\begin{cases} 15x+31y=-3 \\\\ x=-y+3 \ \ | \times 15\end{cases} \Leftrightarrow \ominus\begin{cases} 15x+31y=-3 \\\\ 15x=-15y+45 \ \ \end{cases} \Leftrightarrow \\\\\\ 15x-15x+31y=-3-(-15y)-45 \\\\ 31y=15y-48 \\\\ 31y-15y=-48 \\\\ 16y=-48 \ \ |\div 16 \\\\ y=-3 \ \ ; \ \ x=-y+3=3+3=6 \\\\[/tex]

Over 5 days, Jaasiel practices soccer for a total of 3 hours. Jaasiel practices baseball for the same amount of time each day. If he practiced soccer and baseball for a total of 30 hours, how many hours per day did Jaasiel practice baseball? *
Answer:
3 HOURS
Step-by-step explanation:
HE PRACTICED 3 HOURS A DAY IN BOTH SPORTS MEANING IN 1 DAY HE PRACTICED A TOTAL OF 6 HOURS 6 HOURS A DAY FOR 5 DAYS IS EQUAL TO 30 HOURS OF PRACTICE A WEEK FOR BOTH SPORTS. SO 6 HOURS A DAY TOTAL AND 3 HOURS A DAY IF YOU ONLY COUNT 1 OF THE 2 SPORTS MENTIONED.
It takes 10 seconds to move 1 centimeter. How long will it take the snail to move 2.5 centimeters
Answer:
25 sec
Step-by-step explanation:
2.5 cm is 2.5 times 1 cm, so it will take 2.5 times 10 seconds.
2.5 * 10 sec = 25 sec
The snail take 25 seconds to move 2.5 centimeters.
What is Measurement unit?
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that;
The snail take 10 seconds to move 1 centimeter distance.
Now,
For covering 2.5 centimeters , the time is calculated as;
Since,
The snail take 10 seconds to move 1 centimeter distance.
That is,
⇒ 1 centimeter = 10 seconds
Hence, For the distance 2.5 centimeter, the time is;
⇒ 1 centimeter = 10 seconds
⇒ 2.5 centimeter = 2.5 × 10 seconds
= 25 seconds.
Thus, The snail take 25 seconds to move 2.5 centimeters.

to write an equation of a line that is...
parallel to 2x - 4y = 8
and goes through the point (3, -2)
Answer:
x-2y=7 or y=[tex]\frac{1}{2}x-\frac{7}{2}[/tex]
Step-by-step explanation:
Hi there!
We are given the line 2x-4y=8, and we want to write an equation of the line that is parallel to it and passes through (3, -2)
Parallel lines have the same slope, so it would be a good idea to find the slope of 2x-4y=8
The equation is currently written in standard form (ax+by=c), where a, b, and c are free integer coefficients, but a and b CANNOT be equal to 0, and a CANNOT be negative
In order to find the slope of the line, we can rewrite it in another form; for example, slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)
To rewrite the line in this way, we'll need to isolate y on one side.
So start by subtracting 2x from both sides
-4y=-2x+8
Divide both sides by -4
y=[tex]\frac{1}{2}x[/tex]-2
The slope of the line 1/2, as it's in the place of where m is.
It's also the slope of the line parallel to it.
We can write the equation of the new line in slope-intercept form. Here's what we know so far:
y=[tex]\frac{1}{2}x[/tex]+b (b is a placeholder for the y intercept)
So we'll need to find b.
As the equation passes through the point (3, -2), we can use it to solve for b
Substitute 3 as x and -2 as y:
-2=1/2(3)+b
Multiply
-2=3/2+b
Subtract 3/2 from both sides:
-7/2=b
Substitute -7/2 as b in the equation:
y=[tex]\frac{1}{2}x-\frac{7}{2}[/tex]
The equation can be left as that, or you can convert it back into standard form
Subtract [tex]\frac{1}{2}x[/tex] from both sides, as the variables are on one side.
[tex]-\frac{1}{2}x[/tex]+y=[tex]-\frac{7}{2}[/tex]
Remember that the coefficient in front of x (a) CANNOT be negative, and also the free coefficients a, b, and c CANNOT be fractions.
So in order to clear the fractions and to change the signs, multiply both sides by -2
x-2y=7
Hope this helps!
What is the value of the x variable in the solution to the following system of equations?
2x - 3y = 3
5x - 4y = 4
Answer:
x = 0
Step-by-step explanation:
Solve 2x - 3y = 3 for x:
[tex]2x - 3y = 3[/tex] [tex]2x - 3y + 3y = 3+ 3y[/tex] (add 3y to both sides)[tex]2x = 3y + 3[/tex] [tex]\frac{2x}{2} = \frac{3y+3}{2}[/tex] (divide both sides by 2)[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex]Substitute 3/2(y) + 3/2 for x in 5x - 4y = 4
[tex]5x - 4y = 4[/tex] [tex]5(\frac{3}{2}y + \frac{3}{2}) - 4y = 4[/tex] [tex]\frac{7}{2}y + \frac{15}{2} = 4[/tex] (simplified both sides of equation)[tex]\frac{7}{2}y + \frac{15}{2} - \frac{15}{2} = 4 - \frac{15}{2}[/tex] (subtract 15/2 from both sides)[tex]\frac{7}{2}y = -\frac{7}{2}[/tex] [tex]\frac{7}{2}y * \frac{2}{7} = \frac{-7}{2} * \frac{2}{7}[/tex] (multiply both sides by 2/7)[tex]y = -1[/tex]Substitute -1 for y in x = 3/2(y) + 3/2
[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex] [tex]x = \frac{3}{2}(-1) + \frac{3}{2}[/tex] [tex]x = -\frac{3}{2}+ \frac{3}{2}[/tex] (simplified both sides of equation)[tex]x = 0[/tex]Therefore, the value of the x-variable is 0.

∠6 = 120
Step-by-step explanation:
This question has nothing to do with parallel lines.
Angles 5 and 6 form a linear pair, so are supplementary.
∠6 + ∠5 = 180°
3x +60 = 180
3x = 120 . . . . . . . . . subtract 60
x = 40 . . . . . . . . . . . divide by 3
Angle 6 is the supplement of angle 5 as shown above.
∠6 = 3x = 120

There are 6 possible outcomes on a single fair dice and there are two dice: 6 × 6 = 36. Hope this helps!
Answer: 36
Explanation:
There are 6 sides for either die, which leads to 6*6 = 36 outcomes with two dice. Think of a table with 6 rows and 6 columns. Each of the 36 inner cells represents a different dice sum.
