Answer:
Width = 12 cm
Length = 14 cm
Step-by-step explanation:
Rectangle:
Let the width = x cm
So, the length = (x+2) cm
Perimeter = 52 cm
2 *(l+b) = 52
2 *(x+2 + x) = 52
2 * ( 2x + 2) = 52
2x + 2 = 52/ 2
2x + 2 = 26
2x = 26- 2
2x = 24
x = 24/2
x = 12
Width = 12 cm
Length = 14 cm
So, 350 out of 1750
350/1750=
.1828/1
percent is parts out of 100 so x%=x/100
make bottom number 100
0.1828/1 times 100/100 =18.28/100=18.28%

Answer:
1. C.
2. D.
3. C.
Step-by-step explanation:
1. Simplify to get 1/9 and 1/18, 3/27 = 4/36
2. Jeanne : Jake simplified (would be C if un-simplified)
3. 216/5 = 43.2
Answer:
Step-by-step explanation:
Triangle PQR is given to be a right triangle, so the Pythagorean Theorem can be used to determine that PQ is the hypotenuse.
It is given that x^2 + y^2 =z^2 in triangle ABC, so AB = PQ.
The information shows that the triangles are congruent because their three sides are congruent. Therefore, to show that triangle ABC is a right triangle, we can use corresponding parts of the congruent triangles to show that BCA is a right angle.
If you're talking about #5, where you have to graph the equation . . .
All you have to do is find two points on the graph, and draw a line between them.
How do you find points ? That's where <u>you</u> are in control !
Just pick any number you like for 'x', and then use the equation
to calculate the 'y' that goes with it.
Examples:
Pick 'zero' for 'x'.
Y = (1/2)x + 3
<u>Y = 3</u>
Pick 10 for 'x'.
y = (1/2)x + 3
y = 5 + 3
<u>y = 8</u>
Just create two points that way, using the equation. Then mark
the two points on the graph, and draw a line through the two points.
