Mandy and Jordan each bought some of the same notebooks and the same three-ring binder. Mandy paid $5.85 for 3 notebooks and 1 binder. Jordan paid $4.65 for2 notebooks and 1 binder. What is the price of one ofthe notebooks?
Answers
Answer:
$1.20
Step-by-step explanation:
Mandy and Jordan each bought some of the same notebooks and the same three-ring binder.
Mandy paid for 3 notebooks and 1 binder = $5.85
Jordan paid for 2 notebooks and 1 binder = $4.65
Mandy paid more money for extra one notebook = 5.85 - 4.65
= $1.20
Therefore, the price of one notebook is $1.20.
let's turn this into 2 equations, n being notebook price, and b being binder price ->
mandy -> 3n + b = 5.85
jordan -> 2n + b = 4.65
we need to take one equation, simplify for b, and plug it into the other equation, let's take jordan's equation for this ->
b = 4.65 - 2n
plug it into mandy's equation
3n + (4.65 - 2n) = 5.85
simpify until you get n = 1.20
take this and plug it back into jordan's equation ->
2(1.20) + b = 4.65
simplify until you get b = 2.25
plus this value into mnady's equation ->
3n + (2.25) = 5.85
simplify until you get that n = 2.25

Hello!
To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.
C = 2(36)π
C = 72π
Therefore, the circumference of the circle is 72π inches.

Answer:
105° is the measurement of the original angle.
Step-by-step explanation:
Let the measure of an angle is x.
Then by the statement of the question we can form an equation
x - 15 = 90
(When 15 is subtracted form the measure of an angle, the result is the measure of a right angle)
x = 90 + 15 = 105°
Therefore the original angle is 105°.

The measure of angle C is 36.86°
Step-by-step explanation:
Given : A right angled triangle with right angle at B.
We have to find the measure of angle C.
Consider the given right triangle.
Using trigonometric ratio,
Since, we know tangent is the ratio of perpendicular to base
Using
Here, for angle C we have base = 4 cm and perpendicular = 3 cm
Thus,
Taking both side, we have,
Thus, The measure of angle C is 36.86°

As per the question no (a) The areas corresponding to each other are triangles ABC and DEF, and the common ratios are AB/DE = 5/2 and BC/EF = 5/2. Lets find the solution :-
Now,
In triangles ABC and DEF, we have the following:-
∠A and ∠D are congruent, so we can say ∠A = ∠D.
∠C and ∠F are congruent, so we can say ∠C = ∠F.
Now, to find which areas correspond, let's compare the ratios of corresponding sides:-
AB/DE = 15/6 = 5/2
BC/EF = 20/8 = 5/2
These ratios are equal, indicating that sides AB and DE correspond, and sides BC and EF correspond. So, the areas corresponding to each other are triangles ABC and DEF, and the common ratios are AB/DE = 5/2 and BC/EF = 5/2.
