Which of the following best shows the commutative property of multiplication?
4 x 3 = 3 x 4
4 x 3 = 4
4 x 3 = 4 ÷ 1/3
4 x 3 = (2 x 2) x 3
Answer:
[tex]4*3=3*4[/tex]
Step-by-step explanation:
The commutative property of multiplication states that [tex]a*b=b*a[/tex].
In the first equation, we have that [tex]4*3=3*4[/tex], which is a clear application of the commutative property.
So, the answer is [tex]4*3=3*4[/tex] and we're done!
Answer:
it's the first one cause the commutative property is multiplying in any order without changing the product.... I think?
there are 76 milligrams of sodium in a 3ounce serving at skinless chicken how much sodium would be in 8 ounce of skinless chicken to the nearest tenth
Answer:
202.7 milligramsHope this helped :)Answer:
202.7
Step-by-step explanation:
76 divided by 3 to see how many milligrams of sodium is in 1 once of chicken, so it would be 25.33... (or you xould simplify to 25.4.) Then you times by 8 to see how much is in 8 ounces

In ∆PQR, m P = 60°, m Q = 30°, and m R = 90°. Which of the following statements about ∆PQR are true? Check all that apply.
A. PQ = √3 • PR
B. PQ = 2 • PR
C. QR = 2 • PR
D. QR = √3/2 • PQ
E. QR = √3 • PR
F. PR = √3/2 • PQ
Answer:
C. QR = 2 • PR
Step-by-step explanation:
According to given information we can draw a right triangle with angle measures as follows :
30-60-90 and for this special right triangle the side length would follow as:
The side length that sees angle measure 30 = a
The side length that sees angle measure 60 = a[tex]\sqrt{3}[/tex]
The side length that sees angle measure 90 = 2a
following this information the:
PR(sees 30 degrees) = a (can be represented as PR in this case)
and so
QR(sees 90 degrees) = 2a (2*PR in this case)
PQ(sees 60 degrees) = a[tex]\sqrt{3}[/tex] ([tex]\sqrt{3}[/tex] *PQ in this case)
The correct option is C. QR = 2 • PR

Help please. I give brainliest. (I accidentally marked this as mathematics its actually history)
Answer:
A
Step-by-step explanation:
I think because The United States allowed Japan to keep its emperor — Hirohito — after the war. Japan's post-war constitution became official on May 3, 1947, and Japanese citizens elected a new legislature. The U.S. and other allies signed a peace treaty in San Francisco formally ending the war in 1951.
According to Office Of The Historian," The outbreak of the Korean War in 1950 provided SCAP with just the opportunity it needed to address this problem, prompting some occupation officials to suggest that, “Korea came along and saved us.” After the UN entered the Korean War, Japan became the principal supply depot for UN forces. The conflict also placed Japan firmly within the confines of the U.S. defense perimeter in Asia, assuring the Japanese leadership that whatever the state of its military, no real threat would be made against Japanese soil."
Answer: Japan produced supplies for the United States during the Korean War.

Find the midpoint of the segment with the given endpoints.
(-10,- 6) and (-3,7)
Step-by-step explanation:
in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.
now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.
when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).
so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.
xm, ym are the coordinates of the midpoint.
xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5
ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5
so, the midpoint is (-6.5, 0.5)

Consider the quadratic function f(x)=8x2−7x+6. What is the constant of the function?
Answer:
6 is the constant :
because it is never going to change
f(x), and others that contain x will change based on the value x
Since 6 doesn’t have the c with it it will be constant
