Answer:
67.5 kg
Step-by-step explanation:
To determine the weight of 45 books, we need to determine the weight of one book, using the equation (30 books = 45 kg). This can be done by dividing 30 to both sides of the equation. Therefore,
⇒ 30 books/30 = 45/30 kg⇒ 1 book = 45/30 kg = 3/2 kg = 1.5 kgWe obtained the following equation;
⇒ 1 book = 1.5 kgNow, multiply both sides by 45 to determine the weight of 45 books.
⇒ 1 book × 45 = 1.5 kg × 45⇒ 45 books = 67.5 kgTherefore, the weight of 45 books is 67.5 kg.
Answer:
[tex]\huge\boxed{\bf{45books = 67.5kg}} [/tex]
Step-by-step explanation:
Given:-
30 books = 45kgTo find:-
45 books = ?Ans:-
30books = 45kg
45books = y kg
Let's find 45 books (y)
[tex]\sf \to \frac{30}{45} = \frac{45}{y}[/tex]
[tex]\sf \to 45*45 = 30*y[/tex]
[tex]\sf \to 2,025 = 30*y[/tex]
[tex]\sf \to y = \frac{2,025}{30}[/tex]
[tex]\sf \to y = 67.5kg[/tex]
~therefore 45books = 67.5kg

Answer:
1. $1,122
2. $485.25
3. $440
4. $2,047.25
Step-by-step explanation:
1. 22 feet * 17 feet = 374 square feet * $3 per square foot = $1,122
2. 17 feet * 10 feet * 4 walls = 680 square feet. 680 feet - (7ft*3ft for the door) - (2*2ft*3ft for the windows) = 647 square feet * $0.75 per square foot = $485.25
3. 374 square feet/ $88 per gallon = 4.25 gallons which rounds up to 5 gallons, and 5 gallons at a cost of $88 per gallon = $440
4. $1,122 + $485.25 + $440 = $2,047.25

Parallel lines r and s are cut by two transversals, parallel lines t and u.
Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of r and u, 13, 14, 15, 16.
How many angles are alternate exterior angles with angle 5?
Answer:
The alternate exterior angles with angle 11 are angle 13 and angle 5.
Step-by-step explanation:
Two angles are called Alternate exterior angles if
1. They are on the exterior side of parallel lines and
2. Lie on the opposite sides of the transversal line.
It is given that
[tex]r||s[/tex] and [tex]t||u[/tex]
From the figure it is noticed that the angle 13 and angle 5 are on the exterior side of parallel lines and they lie on the opposite sides of the transversal line.
Therefore alternate exterior angles with angle 11 are angle 13 and angle 5.

5. Eunice is flying a kite with vertices at points A(0, 0), B(0, 4), C(7, 7), and D(4, 0). If each unit
represents one foot, what is the area of Eunice's kite?
The area of Eunice's kite is [tex]2\sqrt{58}[/tex].
What is the kite?A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces.
Eunice is flying a kite with vertices at points A(0, 0), B(0, 4), C(7, 7), and D(4, 0).
If the diagonals in a quadrilateral are perpendicular to each other then the area is one-half of the product of the diagonals.
All Kites and rhombi fall in this category.
By the distance formula;
[tex]\rm AB =\sqrt{(0-0)^2+(4-0)^2} =\sqrt{0+16} =\sqrt{16} =4\\\\BC =\sqrt{(7-0)^2+(7-4)^2} =\sqrt{49+9} =\sqrt{58} \\\\CD =\sqrt{(4-7)^2+(0-7)^2} =\sqrt{49+9} =\sqrt{58}\\\\AD =\sqrt{(0-0)^2+(4-0)^2} =\sqrt{0+16} =\sqrt{16} =4\\[/tex]
The area of Eunice's kite is;
[tex]\rm Area = \dfrac{1}{2} \times AB \times BC\\\\Area =\dfrac{1}{2} \times 4 \times \sqrt{58} \\\\Area =2\sqrt{58}[/tex]
Hence, the area of Eunice's kite is [tex]2\sqrt{58}[/tex].

False - should be 7 root 5
Step-by-step explanation:
y = hypotenuse, longest side (so, it's the value of c)
Using the value of x (21) & y as (14) in the equation a^2 + b^2 = c^2
I get the value of 7 root 3 as shown above, to be 7 root 5 instead.
I know part of the question is cut off, but I'm sure that it's asking you to prove wrong or right if the triangle could be a right-angle triangle (with right measurements) & it's one because the last missing angle is 90 degrees.

Gina is buying 24 oranges. Two stores offer the following deals:
Store A: 12 oranges for $6.48
Store B: 5 oranges for $2.65
Gina can buy oranges individually.
How much will Gina save if she buys 24 oranges at Store B?
Show your work.
Answer:
She saves 24 cents by buying 24 oranges at store B
Step-by-step explanation:
Price per orange A = 6.48 / 12 oranges = .54 per orange
.54 * 24 oranges = 12.96 for store A
Price per orange B = 2.65 / 5 = .53 per orange
.53 * 24 oranges = 12.72 for store B
12.96 - 12.72 = .24 dollars (24 cents)
