Answer:
X changes to Multiply symbol
Step-by-step explanation:
A)
-5 X 3 + 17
-5 X 3 = -15
-15 + 17 = 2
B)
3 X 3 - 22
3 X 3 = 9
9 - 22 = 13
C)
2 X 3 -25
2 X 3 = 6
6 - 25 = 19
D)
6 X 3 - 39
6 X 3 = 18
18 - 39 = -21

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for the correct calculation of velocity?
A. The Starting point
B. The direction
C. The end point
D. The time per meter
Answers
Answer:
The end point as when we multiply 4.3 x 4.7 we get 20.21 and if there is no end point in distance shown we can assume she displaced 20 meters in 4.7 and that 4.26 seconds had a larger end point.
However a starting and end point is always required.
Step-by-step explanation:
4.7 x 20
Change minutes into seconds (so that the final result would be in meters per second) we do not have to do this as all time is already in seconds.
= 4.7 seconds, Divide the distance by time: velocity = 20/4.7 = 4.25531915
= 4.3 m/s

3/2 = 5d - 1/2
solve for d
Answers
Answer:
D = 2/5 or 0.4
Step-by-step explanation:
3/2 = 5d - 1/2
move the terms
3/2 - 5d = -1/2
calculate the difference
-5d = -2
divide both sides by -5
2 = 2/5
3/2 = 5d - 1/2
+1/2 +1/2
2=5d
divide both sides by 5
D = 2/5

triangle ABC △ABC triangle, A, B, C is rotated -120° about point P create ΔA' B' C'
Answers
Answer:
40°
Step-by-step explanation:
Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.
After rotational transformation, the measure of angle ∠A' = 40°.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The diagram shows the two triangles.
Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.
From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.
Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]
Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.

I WILL MARK AS BRAINLIEST! Find the surface area and Volume of the following figures
Answers
Step-by-step explanation:
a) is really easy, right ?
the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.
there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1
SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²
the volume is just length×width×height
V = 7×2×1 = 14 in³
b)
a little bit more difficult, but with a little trick just as easy.
the surface area consists of the 2 circle areas and the mantle "coating".
the area of a circle is pi×r².
we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.
the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.
now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.
circumference of a circle is 2×pi×r
so the surface area is 2×circle + (circumference circle)×12
SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =
≈ 534.07 ft²
the volume is one base area (circle) times height
V = pi×5²×12 = 300pi ≈ 942.48 ft³

The second triangle with sides 3 and x be ΔCDE
ΔABC ≅ ΔCDE (they are congruent) as:

2) ∠ABC = ∠CDE = 90° (given)
Hence we can say,
AC/CE = BC/CD
= 7/x = 3.5/3

2) range is all possible y values so the graph goes all the way up but stops at -4 when going down, but it doesn’t touch 4 so it’s a parenthesis not a bracket (which is used when it’s equal to that number)
3) as x increases in number from negative to positive than y is also increasing (based on the graph)
4) as x decreases it stops a -4 but and doesn’t pass this y value ( it’s finding the limit)
5) x intercept is when y=0
6) y intercept is when x=0

I WILL MARK AS BRAINLIEST! Find the area and perimeter of the following figures
Answers
Step-by-step explanation:
it is really not complicated. we only need to type the numbers into the calculator.
so, what's the problem ? you don't know what a perimeter is ? it is the circumference, the total way you have to go when waking all around the figure.
you don't know the formulas for the areas of specific figures ?
let's start :
a)
the area of a rectangle is length×width. I hope you know this at least since first grade.
the important thing here is : the result is in² and not just in. it means an area counts the little squares that fill that area.
A = 30×8 = 240 in²
the perimeter, as explained, is the whole way around it. so, in the end, as you can easily see, we would have to go 2 times the long side and 2 times the short side.
the result is in (just a length, a distance not an area, not a cube, ...).
P = 2×30 + 2×8 = 60 + 16 = 76 in
b)
the area of a triangle is
baseline × height / 2
in this case (a right-angled triangle) we can assume one of the sides enclosing the 90 degree angle as baseline and the other as height (since there is already a 90 degree angle between them).
and again, the result is ft². we could express it also e.g. as in², but since the basic measures are in ft, it makes it better understandable to use ft².
A = 12×5/2 = 6×5 = 30 ft²
the perimeter is even easier than for the rectangle, as we have one side less to count.
and as before, we stay with ft.
P = 12 + 13 + 5 = 30 ft
c)
this is the only more special case.
but it is still easy.
the area is baseline × height.
and our unit of measurement here is cm, so the result will be cm².
A = 10×2 = 20 cm²
the perimeter is the same principle as with a regular rectangle, as the angles don't matter. only the side lengths matter.
so, again, while waking around it, we have to pass 2 times the long side and 2 times the short side.
and the result is a length, a distance again, so, it is cm.
P = 2×10 + 2×4 = 20 + 8 = 28 cm
2. A= 30 feet squared. P=30 feet
3. A= 20 cm squared P= 28 cm
