Answer:
Step-by-step explanation:
Corresponding angles equal 180 degrees when added
6x + 3x = 180

x = 20
angle CBD is 60 and angle GFH is 120
3(20) = 60

Jade buys 4 books that cost the same amount of money. she spends $50.
Part A: in the first box, enter an equation to represent the cost of each book, c, which jade buys.
Part B: in the second box, enter the cost of each book represented by c in this situation.
The equation, representing the cost of each book, c, which Jade buys is c = 50/4. The cost of each book represented by c in this situation is $12.5
How to interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b[/tex] = a divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is so because as a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )
For this case, we're given that;
Jade buys 4 booksEach book's cost is same, represented by 'c' (in dollars)Total amount spent on buying those 4 books = $504 books = $50 in cost
Dividing 4 books in 4 groups equally gives 1 book per group.
Dividing $50 in 4 groups equally, which would correspond to those 4 groups of books, would give cost per group, and therefore cost of each book.
We've got:
[tex]\text{Cost of each book} = c = \dfrac{50}{4} \: \rm (in \: dollars)[/tex]
Dividing further, we get:
[tex]c = 50/4 = 12.5 \: \rm dollars[/tex]
Thus, the equation, representing the cost of each book, c, which Jade buys is c = 50/4. The cost of each book represented by c in this situation is $12.5

Answer:
573440 kg
Step-by-step explanation:
Given,
Density of copper ( D ) = 8960 kg / m³
Length of cube ( l ) = 4 meters
To find : Mass of solid cube of copper ( m )
Formula : -
Volume of cube = l³
Volume of cube
= l³
= 4³
= 4 x 4 x 4
= 64 meter³
So,
V = 64 meter³
Formula : -
D = m / V
m = D x V
= 8960 x 64
m = 573440 kg
Hence,
The mass of a solid cube of copper is 573440 kg.

Using the information in the table, how many feet are in 6 yards?
Answer:
18 ft.
Step-by-step explanation:
While you don't have the table provided, this is still a relatively simple problem to solve.
As we know, there are 3 feet per 1 yard (this can be written as 3 ft. = 1 yd. if that's easier to comprehend). So, if we're trying to find how many feet are in 6 yards, you'll write out your equation as 3*6=?. To find what ? is, you'll do the multiplication: 3*6-18.
So, with this, there are 18 feet in 6 yards.
How to find the perimeter and area on a coordinate plane
To find the perimeter and area on a coordinate plane, first find each distance between points and then find perimeter and area with these lengths.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
Let's suppose if we have coordinates (a, b) (c, d), (e, f), and (g, h) on a coordinate plane.
We can use the distance formula to get the length of each side and then adding all the side lengths to get the perimeter of the figure, which is represented by the coordinates on a coordinate plane.
The distance formula can be used:
If we want the distance between (a, b) and (c, d)
[tex]\rm Distance = \sqrt{(c-a)^2+(d-b)^2}[/tex]
Similarly, we can find the distance for all the coordinates.
Let's assume the figure is a rectangle on a coordinate plane:
Then area = length×width
Thus, to find the perimeter and area on a coordinate plane, first find each distance between points and then find perimeter and area with these lengths.

convert decimal 165 into binary
Write 165 as a sum of powers of 2 :
165 = 128 + 37
165 = 128 + 32 + 5
165 = 128 + 32 + 4 + 1
165 = 2⁷ + 2⁵ + 2² + 2⁰
This translates immediately into the decimal expansion of a binary number,
165 = 1×2⁷ + 0×2⁶ + 1×2⁵ + 0×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰
so that
165₁₀ ≡ 1010 0101₂
Answer:
10100101₂
Step-by-step explanation:
To convert decimals to binary, you have to divide the decimal by 2 until it meets zero. Also, while dividing the number by 2 you have to write the remainder in each step. And then you have to write the remainders from bottom to top.Let us solve it now.
2 |165
2 |82 - 1
2 | 41 - 0
2 |20 - 1
2 |10 - 0
2 | 5 - 0
2 |2 - 1

The m<1=9y-2 and m<3=7y+16.Find the measure of both angles
The measure of the angles are 91.375°and 88.625°. Both the angles are obtained by the supplementary angle principal.
What exactly are supplementary angles?Supplementary angles are two angels whose total is 180 degrees. When a straight line is crossed by a line, two angles develop on each of the examined straight line's sides.
Two sets of additional angles make up those two-two angles. That is, if supplementary angles are placed next to each other, the exterior sides of their exterior sides will form a straight line.
The given data in the problem is;
∠1 = 9y-2
∠2 = 7y+16
The sum of the supplementary angle is 180
⇒9y-2 +7y+16 = 180
⇒16y +14 =180
⇒16y= 166
⇒ y=10.375
The measure of the angle 1 is;
∠1 = 9y-2
∠ 1 = 9 ×10.375 -2
∠ 1 = 91.375°
The measure of the angle 2 is;
∠2 = 7 × 10.75 +16
∠2 = 88.625°
Hence, the measure of the angles are 91.375°and 88.625°.

Annie traveled 2/7 parts of her trip in the first hour, and then 1/8 parts in the second hour. she plans to rest when she has completed half of her trip.
what part of the trip does Annie still have to travel to reach her destination.
We have to determine part of the trip does Annie still have to travel to reach her destination
Annie traveled 2/7 parts of her trip in the first hour, and then 1/8 parts in the second hour.
She plans to rest when she has completed half of her trip.
2/7 Annie traveled in the first hour = 2/7*60 = 17.1428hours
and 1/8 in one hour,
1/8*60=7.5minutes
What are the total hours to reach the destination?
The distance traveled in the first hour+distance traveled in the second hours=total distance travelled.
Therefore the total distance =7.5+17.14=24.64

Find the missing side length to the nearest tenth of a millimeter. Enter your answer in the box.
Answer:

Step-by-step explanation:
Using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the missing side , then
x² + 5.2² = 7²
x² + 27.04 = 49 ( subtract 27.04 from both sides )
x² = 21.96 ( take square root of both sides )
