Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.
Answers
Answer:
114 units²
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
AB = CD , that is
13x - 7 = 5x + 9 ( subtract 5x from both sides )
8x - 7 = 9 ( add 7 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Then
5x + 9 = 5(2) + 9 = 10 + 9 = 19
3x = 3(2) = 6
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height ), thus
A = 19 × 6 = 114 units²

Find angle T
Angle V is 14x+13 and angle T is 16x-3
I need help figuring out the angle of T through the equation
Answers
Answer:
m∡T = 125°
Step-by-step explanation:
opposite angles in a parallelogram are equal so you can set each expression for V and T equal to each other
14x + 13 = 16x - 3
13 = 2x - 3
16 = 2x
x = 8
∡T: 16(8) - 3
128 - 3 = 125°
The triangular prism above has been created with two equilateral triangles and three congruent rectangles the height of the triangle is 3.5 inches find the surface area of the triangular prism
Answers
Answer:
108 inches square.
Step-by-step explanation:
Here
base= b= 4 inches
height = h=w= 3.5 inches
and length = l= 9 inches
The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by
Area of the 2 Δs= b* h= 4*3.5= 13.5 inches square
Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5 inches square.
Total area = 13.5 + 94.5 = 108 inches square
This can be found by applying another formula.
Surface area of the triangular prism = bh + ( s1+s2+s3) H
= 4*3.5 + (9+9+9)3.5
= 13.5 + 94.5= 108 inches square.
where H is the width of the recatngles which is equal to the height of the triangles.

What percent of 59 is 44.1? Round the answer to the nearest
hundredth of a percent if necessary.
Answers
Answer:
133.78684807256
Step-by-step explanation:
step 1: We need the assumption that 44.1 is 100% since it is our output value
step 2: We need to represent the value we seek in x
step 3: From step 1, it follows that 100% = 44.1
step 4: In the same vein x% = 59
step 5: This give us a pair of simple equations:
100% = 44.1 (1)
x% = 59 (2)
step 6: by simplify dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have
[tex] \frac{100}{x} = \frac{44.1}{59} [/tex]
step 7: Taking the inverse (or reciprocal) of both sides yields
[tex] \frac{x}{100 } = \frac{59}{44.1} [/tex]
= x = 133.78684807256
Therefore, 59 is 133.78684807256% of 44.1
