Answer:
The number of walnut pounds we need to add is 10
Step-by-step explanation:
We need to make a mixture that costs $1 per pound.
That means that the total cost of our mixture, divided by the number of pounds must be equal to 1.
[tex]\frac{MixtureCost}{NumberOfPounds} = 1[/tex]
Well, we know that the total cost of our mixture is equal to the cost of the cashews + cost of walnuts.
[tex]MixtureCost = CashewsCost + WalnutsCost[/tex]
We also know that we'll buy 8 pounds of cashews that cost $1.25 each and some amount of pounds (which we'll call x) of walnuts that cost $0.80.
Knowing all of that, we can write this:
[tex]MixtureCost=8*1.25 + x*0.8[/tex]
If we make that multiplication, we have that
[tex]MixtureCost=10+x*0.8[/tex]
Now that we know the cost of our mixture, we just need to know the total number of pounds... But we already know that, don't we?
We know that there are 8 pounds of cashews and x pounds of walnuts, so here's what we can write:
[tex]NumberOfPounds=8+x[/tex]
Now, if we plug in the values we found in the first equation, here's what we have:
[tex]\frac{10+x*0.8}{8+x}=1[/tex]
The 8+x is dividing, so i'll pass it to the other side multiplying:
[tex]10+0.8*x=x+8[/tex]
The 10 in the left side will go to the right side with a negative sign:
[tex]0.8x=x-2[/tex]
Now, if I pass the x from the right side to the left one changing signs:
[tex]0.8x-x=-2\\\\-0.2x=-2[/tex]
By changing signs from both sides, we have that:
[tex]0.2x = 2\\\\x = 10[/tex]
Therefore, the number of walnut pounds we need to add is 10
Round 0.675 to the nearest tenth
Answer:
0.70
Step-by-step explanation:
it’s 0.70 because the 0.675 is rounded
The 7 is more than 5 so it’s closer to 8 which that you round up the 6 to a 7 and the same thing with 5. So that is how I know it’s 0.70 after rounding it.
Answer:
0.70
Consider the rounding rule for each place.

What sequence of transformations when applied to triangle HIG, shows that triangle HIG is similar to triangle H’I’G
Answer:
dilation with respect to the origin by a scale factor of 1/3 followed by a translation of 2 units down
Step-by-step explanation:
The sides of the △ HIJ are:
IH = 6
IJ = 3
Applying the scale factor we obtain the sides of △ H'I'J '.
The scale factor is k = 1/3.
Therefore, we have:
I'H '= 2
I'J '= 1
Then, we move the △ H'I'J 2 units down.
Which is the graph of x≤2?
Answer:
Graph 2
Step-by-step explanation:
We are given the inequality x≤2
First off, with the inequality sign being ≤ rather than <, we know that 2 is also included. This means that x can be equal to 2 or less than 2.
Since 2 is included, we know we are looking for a solid line.
That said, we can eliminate the 1st and 4th graphs because there is a dotted line at 2, meaning that 2 is not included.
Next, based on the inequality sign, we know that values less than 2 satisfy it. So judging by the shaded region on each graph, we see that Graph 2 is the one that satisfies it.
For clarity's sake, one trick you can use is thinking of the inequality sign as an arrow. If it points left, values toward the left should be shaded and vice versa.
Lastly, I'll give you the inequality for each graph.
Graph 1: x<2
Graph 2: x≤2
Graph 3: x≥2
Graph 4: x>2

The codomain of the function [tex]g(x) = 2x^2 + 4x - 1[/tex] is [tex]g(x) = 2x^2 + 4x - 1[/tex]
How to determine the codomain of the function?The equation of the function is given as:
[tex]g(x) = 2x^2 + 4x - 1[/tex]
The above function is a quadratic function and it has the following features:
Domain = [tex](-\infty, \infty)[/tex]
Range: [tex][-3, \infty)[/tex]
When the range and the domain are combined, we have:
[tex][-3, \infty)\ and\ (-\infty, \infty)[/tex]
This gives
[tex][-3, \infty[[/tex]
Hence, the codomain of the function [tex]g(x) = 2x^2 + 4x - 1[/tex] is [tex]g(x) = 2x^2 + 4x - 1[/tex]

Problem 8
The box portion of the shed (ignoring the triangular roof) has a volume of:
length*width*height = 10*8*6.5 = 520 cubic feet
The triangular face on the right side has an area of base*height/2 = 8*2.5/2 = 10. Multiply this with the depth of the triangular prism and we get a volume of 10*10 = 100 cubic feet.
The two sub-volumes combine to 520+100 = 620
Answer: 620 cubic feet===========================================================
Problem 9
Let's find the area of the base
area = side*side = (4.2)*(4.2) = 17.64 sq inches
Then we plug that into the formula below, along with the height of the pyramid
V = volume of a pyramid
V = (1/3)*(area of the base)*(height)
V = (1/3)*(17.64)*(5)
V = 29.4
Answer: 29.4 cubic inchesYour teacher made a typo. She or he should have written [tex]\text{in}^3[/tex] instead of [tex]\text{in}^2[/tex]
Answer:
Okay so you basically need to break this shape into sensible pieces. Such as rectangular and triangular prisms.
first let's find the rectangular prisms' volume, we need to multiply 6.5 with 10 and 8.
6.5×10×8 gives us 520
520 is the volume of the rectangular prism (below the shape)
to find the triangular prism's volume follow these steps:
2.5×8×10×1/2 which gives us 100
now we need to take the sum of these
100+520=620
the answer is C good luck!

Statement:
All integers are irrational numbers.
True or False?
No whole numbers are irrational numbers.
True or False?
Some rational numbers are not integers.
True or False?
Some integers are not whole numbers.
True or False?
Answers:
FalseTrueTrueTrue====================================================
Explanations:
Any integer is rational. For instance, the integer 7 can be written as 7/1 which is a ratio or fraction of integers. Or we could say 14/2 or 21/3 if you wanted to get a bit creative. Since any integer is rational, this means it cannot be irrational. A real number is either rational or irrational. It cannot be both. The name "irrational" literally means "not rational". This is why statement 1 is false.The claim "no whole numbers are irrational numbers" is a true statement because any whole number is rational (for very similar reasoning as explained in statement 1 above), which means it's not possible for a whole number to be irrational.A rational number like 2/3 is not an integer. A quick way to check is to note that 2/3 = 0.67 approximately. Whole numbers and integers do not have any decimal portion to them. We have confirmed statement 3 is true.The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} while the whole numbers is the set {0, 1, 2, 3, ...}. The key difference is that integers involve negative values. Whole numbers do not have negative values. Something like -7 is an integer, but it is not part of the set of whole numbers. Statement 4 is true because of this.find the value of x. cos(67°) = 1/x
[tex]~~~~~\cos 67^{\circ} = \dfrac 1x\\\\\\\implies x = \dfrac 1{\cos 67^{\circ}}\\\\\\\implies x = 2.55[/tex]
