Answer:
x= 4, y = -1
Step-by-step explanation:
2x-3y=11
3x+3y=9
do addition and you should get
5x=20
x=4
plug in x into any equation
12+3y=9
3y= -3
y=-1
The perimeter of a rectangular field is 344m . If the length of the field is 93m , what is its width?
Answer:
width is 79 m
Step-by-step explanation:
P = 2l + 2w
344 = 2(93) + 2w
344 = 186 + 2w
158 = 2w
w = 158/2
w = 79

Answer:
Formula of trapezoid:
B1(base 1) + B2(base 2) x Height(h) x 1/2
Area of Trapezoid:
10(base 1) + 6(base 2) = 16
16 x 5 = 80

A snow cone cup is 12cm tall and has a diameter or 8cm find the volume of the flavored ice that can be held inside the snow cone cup
Answer:
200.96 cm³
Step-by-step explanation:
Volume of a cone = πr²h/3
Pi, π = 3.14
Radius, r = diameter/2
= 8 cm/2
= 4 cm
Height, h = 12 cm
Volume of a cone = πr²h/3
= 3.14 * (4 cm)² * 12 cm / 3
= 3.14 * 16 cm² * 12 cm / 3
= 602.88 cm³/3
= 200.96 cm³
Volume of a cone = 200.96 cm³

find angle a given that a=18.2, angle b=62° and angle c=48°
Answer:
They only add up to 128.2, so if they are asking for the final angle to equal 180, then it would equal 51.8.
Hope that this helps!
How do the points of a figure move in a translation?
A. Same distance and different direction
В. Same distance and same direction
C. Different distance and different direction
D. Different distance and same direction
plz help!!!!!
Answer: В. Same distance and same direction
Step-by-step explanation:
A translation is a rigid transformation that maps each point of the original figure to a new position by the same distance and in the same direction.
It does not change the size or shape of the image.
Thus the correct statement relates to translation is "Same distance and same direction"
Hence, the correct option is B.

Which of the following is not a triangle similarity theorem
Answer:
D. SSA
Step-by-step explanation:
The SSA postulate does not exist because an angle and two sides does not guarantee that the two triangles are congruent. This is because if two triangles have two congruent sides but a non-included congruent side, this does not indicate that it is necessarily congruent.

Answer:
23.8
Step-by-step explanation:
v = 4/3 pi r cube
v =4/3 pi r (15) cube
v=4500 pi
v= 45000 pi /2=4/3pi r cube
1687.5=r cube
r =11.9

Find the distance between the two points in simplest radical form.
(-9,3) and (-3,-5)
Answer:
10
Step-by-step explanation:
Distance Formula: sqrt_/(x1-x2)^2 + (y1-y2)^2
sqrt_/(-9-(-3))^2 + (3-(-5))^2
sqrt_/(-6)^2 + (8)^2
sqrt_/36+64
sqrt_/100
Simplify and you get the number 10.

what is the area???!?!?!
9514 1404 393
Answer:
ac
Step-by-step explanation:
The length of the base is the x-distance between E and H, so is ...
base = a - 0 = a
The height is the y-distance between E and F, so is ...
height = c - 0 = c
The area of the parallelogram is the product of base and height.
A = base×height
A = a×c
The area of the parallelogram is ac.

In the coordinate plane, what is the length of the line segment that connects points at (5,4) and (-3,-1)
Enter your answer in the box. Round to the nearest hundredth.
units
Answer:
9.434 units
Step-by-step explanation:
Given data
points (5,4) and (-3,-1)
x1= 5
y1= 4
x2= -3
y2= -1
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((-3-5)²+(-1-4)²)
d=√((-8)²+(-5)²)
d=√64+25
d=√89
d=9.4339
d= 9.434 units
Hence the distance between the points is 9.434 units
