Ava Made 100 cranes and B made 3/4 of the number of the paper cranes to Ava. Ava gave 9/20 of her cranes to B. Then, B gave 1/4 of her paper to Ava. How many more cranes did B have than Ava in the end?
Answer:
B have 5 more cranes than Ava.
Step-by-step explanation:
As per question statement:
Number of cranes with Ava = 100
Number of cranes with B = [tex]\frac{3}{4}[/tex] of the paper cranes that Ava has
[tex]\therefore[/tex] Number of cranes with B = [tex]\frac{3}{4}\times 100 =75[/tex]
Now, let us proceed step by step.
Step 1: Ava gave [tex]\frac{9}{20}[/tex] of her cranes to B:
i.e. [tex]\frac{9}{20} \times 100 = 5 \times 9 =45[/tex] cranes given to B
Now, number of cranes with Ava = 100 - 45 = 55
Number of cranes with B = 75 + 45 = 120
Step 2: B gave [tex]\frac{1}{4}[/tex] of her paper cranes to Ava:
i.e. [tex]\frac{1}{4} \times 120 = 30[/tex] cranes given to B
Now, number of cranes with Ava = 55 + 30 = 85
Number of cranes left with B = 120 - 30 = 90
So, the answer is:
Number of cranes that B have more than that of Ava = 90 - 85 = 5

Answer:
x = 44°
Step-by-step explanation:
Since this is an isosceles triangle, the other angle that isn't defined is also 68°. So, since all the angles add up to 180°,
x + 68(2) = 180
x + 136 = 180
x = 44°
Answer:
44 is the answer

Triangle ABC is a sketch of a triangular flower bed that has an area of 65.1 square feet.
Trigonometric area formula: Area =
Answer:
40 ft
Step-by-step explanation:
Triangle ABC is given by AB = 13 ft, BC = 10 ft, ∠ACB = 50° and AC = b. Let AB = a = 13 ft, BC = c = 10 ft
Since two sides are given and one angle is given, to find the other side, we use the cosine formula. The cosine formula is given by:
[tex]c^2=a^2+b^2-2abcos(C)\\b^2=c^2-a^2+2abcos(C)\\substituting\ values:\\b^2=13^2-10^2+2*10*bcos(50)\\b^2=169-100+12.86b\\b^2-12.86b=69\\b^2-12.86b-69=0\\ solving\ simultaneously\ gives:\\b=16.93\ ft[/tex]
The perimeter of the triangle is given by:
Perimeter = AB + BC + AC = 13 + 10 +16.93 = 39.93 ft ≈ 40 ft
The measurement of the supplement of an angle is 39 more than half the angle. find the measure of the angle and its complement
Answer: 94, 86
Step-by-step explanation:
x + x/2 + 39 = 180
x + x/2 = 180 - 39
x = 94
Other angle is 180 - 94 = 86

Answer:
A
Step-by-step explanation:
The important thing here is that for the quadratic formula to be able to be applied you need the equation to be equal to 0. Then in this case we know that once it is equal to 0 the coefficients have to be: a = 1, b = 3, c = 24
Only A satisfies both conditions

C) The determinant of 2 x 2 matrix A is 3. If you switch the rows and multiply the first row by 6 and the second row by 2, explain how to find determinant and provide the answer
Answer:
Step-by-step explanation:
A 2 × 2 matrix has 2 rows and 2 columns
Let us assume that matrix A is expressed as
a b
c d
The determinant of matrix A would be
(a × d) - (b × c)
Given that the determinant of matrix A is 3, it means that
ad + bc = 3
If we switch the rows, the first row becomes cd and the second row becomes ab. If we multiply the first row by 6 and the second row by 2, the matrix becomes
6c 6d
2a 2b
The determinant would be
(6c × 2b) - (2a × 6d)
Determinant = 12bc - 12ad

LCM of 3 and 4 = 12.
So,
Numerator of fractions = 8x-4 and 9x
Now they have the same denominator, combine both fractions.Now you have

Reflect triangle a in the x axis to give triangle b. Then rotate your triangle b 90 degrees clockwise around the origin to give triangle c. Describe fully the single transformation that maps triangle a onto c
Answer:
The single transformation that maps a onto c is the reflection of the triangle a about the line y = -x
Step-by-step explanation:
To answer the question, we note that the result of reflection of a point (x, y) across the x axis is given as follows;
Coordinates before reflection = (x, y), Coordinates after reflection = (x, -y)
Also, when we rotate a point, (x, y), 90° clockwise, we have;
Image point before 90° clockwise rotation = (x, y), Image point after 90° clockwise rotation = (y, -x)
Therefore, the rotation of the point (x, -y), 90° clockwise will give
Image point before 90° clockwise rotation = (x, -y), Image point after 90° clockwise rotation = (-y, -x)
Which gives the combined transformation as (x, y) → (-y, -x) which is the rule equivalent to reflection about the line y = -x.
The laundry has been sorted into dark clothes and light clothes. The number of dark clothes is three more than twice the number of light clothes. The laundry is 60% dark clothes. Choose the equation that best represents this scenario. x over quantity 2x plus 3 equals 40 over 60 x over quantity 2x plus 3 equals 60 over 40 x over quantity 2x plus 3 equals 40 over 100 x over quantity 2x plus 3 equals 60 over 100
Answer:
x over quantity 2x plus 3 equals 40 over 60
Step-by-step explanation:
Let light clothes=x
Number of dark clothes = 2x + 3,
Dark clothes are 60% of total clothes
Light clothes=100%-60%
=40%
Light clothes / dark clothes = percentage of light clothes / percentage of dark clothes
x / 2x+3 = 40 / 60
x over quantity 2x plus 3 equals 40 over 60
Expression for this situation will be [tex]\frac{x}{2x+3}=\frac{60}{40}[/tex].
Let the number of dark cloths = y
And the number of light cloths = x
"The number of dark cloths is three more than twice the number of light cloths".
Therefore, equation will be,
y = 2x + 3 ----- (1)
"The laundry is 60% dark cloths"
Equation for this statement will be,
y = [tex]\frac{60}{100}(x+y)[/tex]
y = 0.6x + 0.6y
y - 0.6y = 0.6x
0.4y = 0.6x
[tex]\frac{y}{60}=\frac{x}{40}[/tex]
Now substitute the value of y from equation (1),
[tex]\frac{2x+3}{40}=\frac{x}{60}[/tex]
[tex]\frac{2x+3}{x}=\frac{40}{60}[/tex]
[tex]\frac{x}{2x+3}=\frac{60}{40}[/tex]
Therefore, expression for this situation will be [tex]\frac{x}{2x+3}=\frac{60}{40}[/tex].
