Answers
The dot plot shows the frequency or length of the tadpoles
The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches
How to determine the total length?From the dot plot, we have the following parameters:
3 tadpoles have a length of 1/82 tadpoles have a length of 1/4So, the total length is:
Total = 3 * 1/8 + 2 * 1/4
Evaluate the product
Total = 3/8 + 1/2
Rewrite as;
Total = 3/8 + 4/8
Evaluate the sum
Total = 7/8
Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

A triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle Thus, the triangle is not acute because 2² + 4² < 5².
What is the acute angle?An acute angle is defined as the measure of an angle that is less than 90 degrees.
The square of the hypotenuse of a right triangle with the given sides would be 2² +4² = 20.
So, that hypotenuse would be √20, about 4.47.
The long side of this triangle is longer than that, hence the angle opposite is larger than 90°. The triangle with sides 2, 4, and 5 is an obtuse triangle.

What is a perfect square?A perfect square is a number system that can be expressed as the
square of a given number from the same system.
1. Anyah states that the square root of 0.89 is between 0.44 and 0.45 because 0.44<0.89/2<0.45. This statement of anyah is false because the√0.89 = 0.9433.
2. Matthew states that the square root of 0.89 is between 0 and 1 because 0< 0.89<1. the value lies between 0 and 1 So this statement is true.
3. Rhoda states that the square root of 0.89 is between 0.9 and 1.0 because of 0.9^2 <0.89<1.0. This statement is true because the square of 0.9 is 0.81 and 1.0 is 1, and 0.89 lies in between them. So the statement is true.
4. Ming states that the square root of 0.89 is between 0.93 and 0.95 because of 0.93^2 <0.89<0.95^2. this statement is also true.

Answers
The second order polynomial that involves the variable x (border inside the rectangle) and associated to the unshaded area is x² - 62 · x + 232 = 0.
How to derive an expression for the area of an unshaded region of a rectangle
The area of a rectangle (A), in square inches, is equal to the product of its width (w), in inches, and its height (h), in inches. According to the figure, we have two proportional rectangles and we need to derive an expression that describes the value of the unshaded area.
If we know that A = 648 in², w = 22 - x and h = 40 - x, then the expression is derived below:
A = w · h
(22 - x) · (40 - x) = 648
40 · (22 - x) - x · (22 - x) = 648
880 - 40 · x - 22 · x + x² = 648
x² - 62 · x + 232 = 0
The second order polynomial that involves the variable x (border inside the rectangle) and associated to the unshaded area is x² - 62 · x + 232 = 0. [tex]\blacksquare[/tex]

The maximum revenue of the craftsman is an illustration of objective function
The craftsman can at most make $500, if he makes 100 bracelets
How to determine the maximum revenue?Represent bracelet with b and necklace with n.
From the question, we have:
b n Total
Unit 10 20 1000
Time 10 40 1600
Cost 5 7.5
So, we have the objective function to be:
Max C = 5b + 7.5n
And the constraints are:
10b + 20n ≤ 1000
10b + 40n ≤ 1600
b ≥ 0
n ≥ 0
From the given graph of the constraints, we have the following feasible points
(b,n) = (0,0) (40,30) (0,50) and (100,0)
Substitute these values in the objective function
C(0,0) = 5(0) + 7.5(0) = 0
C(40,30) = 5(40) + 7.5(30) = 425
C(0,50) = 5(0) + 7.5(50) = 375
C(100,0) = 5(100) + 7.5(0) = 500
The maximum revenue is at the point (100,0)
Hence, the craftsman can at most make $500, if he makes 100 bracelets

Answers
The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.
The volume of the larger sphere = 64π cm³
let us take the radius of the larger sphere r
So, 4/3*π*r³ =64π
r³=48
r=2∛6
What is the surface area of a sphere?The surface area of a sphere with radius r is 4πr².
So, the surface area of the larger sphere = 4π(2∛6)²
The surface area of the larger sphere = 16π∛36
Hence, The surface area of the larger sphere with a volume of 64π cm³ is 16π∛36 cm³.

Answers
Answer:

Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0 (a ≠ 0 )
the discriminant b² - 4ac informs us about the nature of the roots
• If b² - 4ac > 0 then roots are real and irrational
• If b² - 4ac > 0 abd a perfect square then roots are real and rational
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 the roots are complex
4x² + 6x - 7 = 0 ← is in standard form
with a = 4, b = 6, c = - 7 , then
b² - 4ac = 6² - (4 × 4 × - 7) = 36 - (- 112) = 36 + 112 = 148
since b² - 4ac > 0 then roots are real and irrational
