Which of these expressions shows a correct way to set up the slope formula for the line that passes through the points (3, 6)
and (-7, -4)?
Answers
Answer:
C
Step-by-step explanation:
Line slope calculation formula: The difference of the second components is divided by the difference of the first components. It should be noted that they are reduced in order. The components of a point on the numerator and denominator must always be written first.
Answer:
C
Step-by-step explanation:
Slope formula:
[tex]\mathsf{slope=\dfrac{(y_2-y_1)}{(x_2-x_1)}}[/tex]
where [tex]\mathsf{(x_1,y_1)}[/tex] and [tex]\mathsf{(x_2,y_2)}[/tex] are points on the line
Given:
[tex]\mathsf{(x_1,y_1)=(3,6)}[/tex][tex]\mathsf{(x_2,y_2)=(-7,-4)}[/tex][tex]\mathsf{slope=\dfrac{(-4-6)}{(-7-3)}}[/tex]

Circle A has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. The diameter of circle B is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle.
Part B: Use the formula for area and solve for the value of pi for each circle.
Part C: What observation can you make about the value of pi for circles A and B?
Answers
Answer:
A. The circumference is (pi)d where d is the diameter. So (pi) for circle A is 21.98/7=3.14 and for B is 18.84/6=3.14.
B. Area is (pi)r^2 where r=radius or d/2. So for circle A (pi)=38.465/(3.5)^2=3.14 and circle B (pi)=28.26/(3)^2=3.14.
C. To two places of decimals (pi) has a value of 3.14 in all cases. This indicates or implies that (pi) is a universal constant applying to all circles using the formulae.

Step-by-step explanation:
Reflection is the mirror image of a shape. Every point in a figure is at equidistant from each corresponding point in another figure from the line of reflection.
Answer:
You can create figure A′ by flipping figure A over its leftmost side. So A and A′ are reflections of each other.
You cannot create figure B′ by flipping figure B over any of its sides. So B and B′ are not reflections of each other.
You can create figure C′ by flipping figure C over its rightmost side. So C and C′ are reflections of each other.
You can create figure D′ by flipping figure D over its leftmost side. So D and D′ are reflections of each other.
You cannot create figure E′ by flipping figure E over any of its sides. So E and E′ are not reflections of each other.
You cannot create figure F′ by flipping figure F over any of its sides. So F and F′ are not reflections of each other.

8 x 4 / 2 gets you the area of the big triangle, which is 32 / 2 = 16
1 x 8 for the rectangle, so far you're at 16 + 8 = 24
The tiny triangles are half the squares so add them together ( 1/2 + 1/2) to get 2/2 = 1/1
add them together to get 24 + 1 = 25
You can also do it as if you take the big triangles and add them together to get a square, you get a 4 x 4 square
Then you have the 1 x 8 rectangle
do the same thing with the tiny triangles as the big triangles, and you get 1
(4 x 4) + (1 x 8) + 1
16 + 8 + 1
24 + 1 = 25

For Part B, I sadly can not answer because the table is needed to solve it, and was not included
For Part C, 1/4 of 6.48 could help us because it can give us the amount needed to cost to buy enough mix for one serving but not how many biscuits. So it's less than 1.62

A is true, see why below
B is true, see why below
C is false, see why below
D is true, see why below
Step-by-step explanation:
A is true because it is adjacent and they are both supplementary to each other, so the sum of them both would lead to 180
B is true because it is vertical to 7, which also means it is the same as 7.
C is false because those angles are not complimentary, therefore they will not add up to 90.
D is true because 4 and 5 are adjacent, they are also supplementary, therefore the sum of 4 and 5 = 180.

B. 6 1/6
C. 7 1/4
D. 7 1/30
PLEASE HELP
Answers
Answer:
the answer is D. 7 1/30
Step-by-step explanation:
first make them into improper fractions:
21/5 and 17/6
second find a common denominater (im using 30) and multiply so they have 30 as the denominater:
126/30 and 85/30
third add the improper fractions:
126/30 + 85/30 = 211/30 and as a mixed number it would be 7 1/30
Answer:
D. 7 1/30
Step-by-step explanation:
4 1/5 + 2 5/6=
The first thing we notice here are the fractions, whenever working with fractions, the first thing to do to make your life easier is to find the common denominator for the fractions. What's a common denominator?? a common denominator is when two fractions can have the same number on the bottom. We know that 5 times 6 gives you 30, so 30 can be our common denominator.
4 1/30 + 2 5/30 =
ok so, we changed our denominator, but now what? since we changed the denominator, this also affects the numerator (the numbers on the top). to fix this, we have to do the same to the numerator as we did to the denominator. to change 5 into 30, we multiplied it by 6, this means we also have to multiply 1 by six, 6/30. Don't forget the other fraction too! Since we multiplied 6 by 5 to get 30, we also have to multiply 5 by 5, 25/30.
4 6/30 + 2 25/30 =
now that the fractions have the same denominator, we can just go ahead and add the digits and numerators!
we know that 4 + 2 = 6, so we can remove them and put 6 at the end of the equation
6/30 + 25/30 = 6
but we aren't done yet, now we add 6 + 25 which gives us 31, out of 30
wait! 31/30? that doesn't sound right. 30 out of 30 automatically gives us a 1, so we can add that to the 6 we got earlier, 6 + 1 = 7. Since we are left with 1/30 we will add this to the final answer: 4 6/30 + 2 25/30 = 7 1/30

Answer:
88/27
Step-by-step explanation:
Convert (2+(2/3)) into a improper fraction. To do this multiply the denominator (3) by the whole number (2) and add the numerator (2). (3*2)+2 = 8. Then put 8 over a denominator which is equal to the denominator of the mixed fraction. So (2+ (2/3) is 8/3) Do the same process with the other fraction.
Then multiply the numerators and denominators of the improper fractions:
(8/3)*(11/9) gives (88/27).
