1. In Part A of this lab, you will measure the dimensions (length, width, diameter) of several geometric shapes. a. Using a ruler, you measure the length of a rectangle to be 12.75 cm and the width to be 3.64 cm. Calculate the area of this rectangle (show work), reporting your answer to the correct number of significant figures.
Answer:
The area of this rectangle is 46.41 cm²
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle of width w and length l is given by:
[tex]A = wl[/tex]
That is, the area of a rectangle is the multiplication of its width by its lengt.
In this question:
[tex]l = 12.75, w = 3.64[/tex]
So
[tex]A = wl = 3.64*12.75 = 46.41[/tex]
Width and length in centimeters, so the area is in square centimeters.
The area of this rectangle is 46.41 cm²

What is ratio of similarity in similar figures?The RATIO OF SIMILARITY between any two similar figures is the ratio of any pair of corresponding sides. Simply stated, once it is determined that two figures are similar, all of their pairs of corresponding sides have the same ratio.
According to the question
Figure A ≈ Figure B
Therefore , ratio of corresponding sides have the same ratio .
Figure A Figure B
4 ft ⇒ 2 ft (given )
( As ratio of [tex]\frac{side\\\ of\\\ figure A}{side\\\ of\\\ figure B} = \frac{2}{1}[/tex] )
10 ft ⇒ 5 ft
3 ft ⇒ 1.5 ft
Now, volume of Figure B (which is cuboid ) = Length * Breath * Height
= 2 * 5 * 1.5
= 15 [tex]ft^{3}[/tex]
Hence, the volume of Figure B is 15 [tex]ft^{3}[/tex]

Find the zeros of the function below.
\small -7x=x^2+12
Answer:
read explanation
Step-by-step explanation:
this is a quadratic equation
first, move the 7x over to the other side so that we have 0 on one side
x^2+7x+12=0
now, we can factor
turn 7x into 3x and 4x, so x^2+3x+4x+12=0
you can turn x^2+3x into x(x+3) and 4x+12 into 4(x+3)
so, our new equation is x(x+3)+4(x+3)=0
that can be turned into (x+4)(x+3)=0 via the distributive property
so, either x+4 or x+3 has to be equal to 0
so, x is either -4 or -3

Answer:
A' = 103°
B' = 100°
C' = 80°
D' = 77°
Step-by-step explanation:
B' = 180 - 80 = 100°
C' = 80 because it is a corresponding to 80°
D' = 180 - 125 = 55, 180 - 48 - 55 = 77°
A' = 360 - 77 - 100 - 80 = 103°

Which measurement is CLOSEST to the distance Jen walks to school each morning? 22 ... C-G.2.1.3. Q.Michael stacks 14 14 14 identical disks to form a cylinder.
Step-by-step explanation:
The volume of the cylinder will be 24.72 in³.
What is a cylinder?In mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.
Given that, the 14 identical disks are stacked to form a cylinder, each disk is 1/4 inch thick, and their diameter is 3 inches, we need to find the volume of the cylinder,
So, here we can say that the height of the cylinder is the sum of the thickness of all the disks,
So, height = 1/4 x 14 = 3.5 inches.
The volume of the cylinder = π × radius² × height.
= 3.14 × 1.5² × 3.5 [radius = diameter / 2]
= 3.14 × 2.25 × 3.5
= 24.72 in³
Hence, the volume of the cylinder will be 24.72 in³.

Answer:
x = 8
y = 14
Step-by-step explanation:
2x + 6 = 4x - 10 (Corresponding angles so they're equal)
2x - 4x = -10 - 6
-2x = -16
x = 8
2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)
2(8) + 6 + 13y - 24 = 180
16 + 6 + 13y - 24 = 180
13y - 2 = 180
13y = 182
y = 14
