Step-by-step explanation:
Distance between two points on the number lines, the difference between the absolute values.
I-8 I - I - 2I = 8 - 2 = 6
The key to finding the distance between two points is to remember that the geometric definition of subtraction is the distance between the two numbers as long as we subtract the smaller number from the larger.
Solution⇛(-8) - (-2)
⇛8 - 2
⇛6

Surface area of a rectangular prism if W = 6in L = 9in and H = 2in
Answer:
Step-by-step explanation:
Two faces are 6” by 9”. Two faces are 6” by 2”. Two faces are 9” by 2”.
Surface are = 2*6*9 + 2*6*2 + 2*9*2 = 108 + 24 + 36 = 168 square inches
A sewing project requires 6 1/8 yd of material that sells
for $4 per yard and 3 1/4 yd of material that sells for $3 per
yard. Choose the best estimate for the cost of the project:
a. Between $30 and $40
b. Between $20 and $34
c. Between $36 and $40
d. Between $33 and $40
The best estimate for the cost of the sewing project is between $30 and $40. Hence option 'a' is correct.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction.
It can be written as the form of [tex]p : q[/tex], which is equivalent to p / q.
Given that,
The sewing project also requires 3 1/4 yards of material selling for $3 per yard.
To calculate the cost of the sewing project:
Compute the cost of each type of material separately and then add them together.
For the first type of material:
We need [tex]6\dfrac{1}{8}[/tex] yards, which is equivalent to 6.125 yards.
The cost of this material would be,
6.125 x 4 = $24.50
For the second type of material:
We need [tex]3\dfrac{1}{4}[/tex] yards, which is equivalent to 3.25 yards.
The cost of this material would be,
3.25 x 3 = $9.75.
Now, add the costs of the two types of materials together:
$24.50 + $9.75 = $34.25.
Hence,
The cost of the project would be between $30 and $40,
Which is option a.

Answer:
56 degrees :)
Answer:
56 degrees
Step-by-step explanation:
the angle next to 76 degrees is a straight line so it is supplementary, meaning it is 104 degrees.
Because the two lines are parallel, and are cut through a transversal, the angle that we just found is actually equal to 48+x because of alternate interior angles. solving for x we get 104-48 = x
x=56

A rectangular storage container without a lid is to have a volume of 10 m3. The length of its base is twice the width. Material for the base costs $15 per square meter. Material for the sides costs $9 per square meter. Find the cost (in dollars) of materials for the least expensive such container. (Round your answer to the nearest cent.)
Answer:
The least expensive cost = $245.32
Step-by-step explanation:
From the information:
Volume of the rectangular container = 10 m²
Assume the width of the container is = w
The base = 2 × width
= 2(w)
Volume = height × base × width
10 = h × 2w × w
[tex]h = \dfrac{10}{2w^2}[/tex]
[tex]h = \dfrac{5}{w^2}[/tex]
Now, to calculate the area of the base; we have:
[tex]Area = length \times width[/tex]
[tex]Area = 2w \times w[/tex]
[tex]Area = (2w^2) \ m^2[/tex]
[tex]Cost \ of \ base = 15 * 2w^2[/tex]
Cost of base = [tex]30w^2[/tex] --- (1)
[tex]Area \ of \ side = 2 ( height \times length ) + 2( height \times width) \\ \\ = 2 (h \times 2w) + 2(h\times w) \\ \\ = 4hw + 2hw \\ \\ = 6 hw \\ \\ = 6 \times \dfrac{5}{w^2} \times w \\ \\ Area = \dfrac{30 }{w} \ m^2[/tex]
Let's not forget that the cost of the sides = $9 per m²
Thus; the cost of the sides will be [tex]= \$ 9 \times \dfrac{30}{w}[/tex]
the cost of the sides [tex]= \dfrac{\$270}{w}[/tex]
Thus the total cost = cost of base = cost of sides
[tex]C(w) = 30w^2 + \dfrac{270}{w}[/tex]
By differentiation;
[tex]C'(w) = \dfrac{dC}{dw} \\ \\ = 30 \times 2w + 270 ( \dfrac{-1}{w^2}) \\ \\ C'(w) = 60 w - \dfrac{270 }{w^2} \\ \\[/tex]
[tex]\text{To determine the minimum cost:} \\ \\ C'(w) = 0 \\ \\ So, 60 w - \dfrac{270}{w^2}= 0 \\ \\ \text{By integrating w.r.t w} \\ \\ w ( 60 - \dfrac{270}{w^3}) =0 \\ \\ \implies 60 - \dfrac{270}{w^3} \\ \\ w^3 = \dfrac{270}{60} \\ \\ w^3 = \dfrac{9}{2} \\ \\ w = (\dfrac{9}{2})^{1/3} \\ \\ w = 1.6509 \ m[/tex]
From; [tex]C(w) = 30w^2 + \dfrac{270}{w}[/tex]
[tex]Cos t = \dfrac{30 w^3+ 270}{w} \\ \\ =\dfrac{30 (\dfrac{9}{2})+ 270}{1.6509} \\ \\ = \dfrac{135+270}{1.6509} \\ \\ = \dfrac{405}{1.6509} \\ \\ \mathbf{Cost = \$245.32}[/tex]

Answer:
[tex]T_6 = 37.96875[/tex]
Step-by-step explanation:
Given
[tex]a =5[/tex]
[tex]r = \frac{3}{2}[/tex]
Required
Determine the 6th term
This is calculated as:
[tex]T_n = ar^{n-1[/tex]
Where
[tex]n = 6[/tex]
Substitute [tex]n = 6[/tex], [tex]a =5[/tex] and [tex]r = \frac{3}{2}[/tex]
[tex]T_6 = 5 * (\frac{3}{2})^{6-1[/tex]
[tex]T_6 = 5 * (\frac{3}{2})^{5[/tex]
[tex]T_6 = 5 * (\frac{243}{32})[/tex]
[tex]T_6 = 5 * \frac{243}{32}[/tex]
[tex]T_6 = \frac{5 *243}{32}[/tex]
[tex]T_6 = \frac{1215}{32}[/tex]
[tex]T_6 = 37.96875[/tex]

Answer:85 degrees
Step-by-step explanation:
Formula for sum of interior angles is (n-2)180. Since there are 7 sides, n-2 is 5.
5 x 180 = 900
Add all the angles given and subtract sum from 900 and you are left with 85 for the missing angle.
3x -3 = 2x
If you do this PLEASE could I have a THOROUGH explanation on how to do it!
Answer:
3x-3=2x, x=3
Step-by-step explanation:
so you want to move all the numbers with x to the left side of the equation
subtract 2x from both sides of the problem
3x-3-2x=0
subtract 2x from 3x
then add 3 to both sides of the equation
x=3
