The inverse of a conditional statement is "If a number is negative, then it has a negative cube root.”
What is the contrapositive of the original conditional statement?
If a number is negative, then it does not have a negative cube root.
If a number does not have a negative cube root, then the number is not negative.
If a number has a negative cube root, then the number is negative.
If a number is not negative, then it does not have a negative cube root.
The contrapositive of the original conditional statement is B. If a number does not have a negative cube root, then the number is not negative.
How to find the contrapositive ?In logic, the contrapositive of a conditional statement is a logically equivalent statement that switches the positions of the hypothesis and the conclusion, while also negating both.
The contrapositive maintains the logical validity of the original statement. If the original statement is true, then the contrapositive is also true, and vice versa. "If a number is negative, then it has a negative cube root." The contrapositive of this statement would be: "If a number does not have a negative cube root, then the number is not negative."

John wishes to choose a combination of two types of cereals for breakfast - Cereal A and Cereal B. A small box (one serving) of Cereal A costs $0.50 and contains 10 units of vitamins, 5 units of minerals, and 15 calories. A small box (one serving) of Cereal B costs $0.40 and contains 5 units of vitamins, 10 units of minerals, and 15 calories. John wants to buy enough boxes to have at least 500 units of vitamins, 600 units of minerals, and 1200 calories. How many boxes of each cereal should he buy to minimize his cost?
Let's assume that John buys x boxes of Cereal A and y boxes of Cereal B. Then, we can write the following system of inequalities based on the nutrient and calorie requirements:
10x + 5y ≥ 500 (minimum 500 units of vitamins)
5x + 10y ≥ 600 (minimum 600 units of minerals)
15x + 15y ≥ 1200 (minimum 1200 calories)
We want to minimize the cost, which is given by:
0.5x + 0.4y
This is a linear programming problem, which we can solve using a graphical method. First, we can rewrite the inequalities as equations:
10x + 5y = 500
5x + 10y = 600
15x + 15y = 1200
Then, we can plot these lines on a graph and shade the feasible region (i.e., the region that satisfies all three inequalities). The feasible region is the area below the lines and to the right of the y-axis.
Next, we can calculate the value of the cost function at each corner point of the feasible region:
Corner point A: (20, 40) -> Cost = 20
Corner point B: (40, 25) -> Cost = 25
Corner point C: (60, 0) -> Cost = 30
Therefore, the minimum cost is $20, which occurs when John buys 20 boxes of Cereal A and 40 boxes of Cereal B.

g working. In a class of 75 students, 45 students study French and 25 students study Ara only. If 10 students study both Arabic and French, (I)illustrate the information on a Venn
; (ii)how many students study (a) only French (b) only one subject;(c) neither Arabic nor French.
Answer:
(i) Attached below. You can copy what I drew
(ii) (a) 35, (b) 60, (c) 5
Step-by-step explanation:
We're told that 25 students study Arabic only and 10 students' study both French and Arabic. Thus, this leaves 40 other students, as 75 - (10 + 25) = 40.We know that 45 students study French and this includes those who study French only and those who study both French and Arabic. Thus, we can subtract the number of students who study both languages from the number of students who study French (generally) to find the number of students who study French only: 45 - 10 = 35.(a) Thus, 35 students study French only.
Thus, we've sorted 70 students so far as 35 + 10 + 25 = 70.To find the number of students who studied neither Arabic nor French, we can subtract 70 from the total number of students in the class: 75 - 70 = 5.(c) Thus, 5 students' study neither Arabic nor French
We can check our work by making sure that:the number of students who study French only + the number of students who study both French and Arabic + the number of students who study Arabic only + the number of students who study neither Arabic nor French equals 75:
35 + 10 + 25 + 5 = 75
45 + 30 = 75
75 = 75
Thus, our numbers are correct.
(b) Also, the number of students who study only subject is 60, as 35 (number of students studying French only) + 25 (number of students studying Arabic only) = 60
I attached a picture of a diagram that you can use and I'll explain what everything means:The box represents the set, which is represented by the letter S in the top-left corner of the pictureF represent the number of students who studied French only, which is why I wrote 35 in this circleThe 10 represents the number of students who study both Arabic and French and likes between the F circle and the A circle A represents the number of students who studied Arabic only, which is why I wrote 25 in this circleThe 5 outside the circles but inside the box represents the number of students who study neither Arabic nor FrenchPLEASEEEE HURRYY
On Giana's map of Texas, there is a close up view of the Dallas/Fort Worth area. The map scale is 1 inch = 3.5 miles. From Garland to Mansfield is 52.5 miles. How far apart are these two cities on the map?
Answer:
The distance between Garland and Mansfield on the map is 15 inches.
Step-by-step explanation:
On Giana's map of Texas, the scale is 1 inch = 3.5 miles. To determine the distance between Garland and Mansfield on the map, we can use the scale to find the corresponding measurement. Given that the actual distance between these two cities is 52.5 miles, we can set up a proportion:
1 inch / 3.5 miles = x inches / 52.5 miles
Cross-multiplying, we have:
3.5 miles * x inches = 1 inch * 52.5 miles
3.5x = 52.5
Dividing both sides by 3.5, we find:
x = 15
Therefore, the distance between Garland and Mansfield on the map is 15 inches.

Find the surface area of the regular pyramid.
A square pyramid. The length of the base is 1 inch. The height of each triangular face is 2 inches.
Answer:
Love helping people so here's the answer :)
Step-by-step explanation:
A square pyramid has 5 faces: 1 square base and 4 triangular faces. The surface area of the pyramid is the sum of the areas of all its faces.
The area of the square base is 1 * 1 = 1 square inch.
The area of each triangular face is (1/2) * base * height = (1/2) * 1 * 2 = 1 square inch.
Since there are 4 triangular faces, the total area of the triangular faces is 4 * 1 = 4 square inches.
Therefore, the surface area of the pyramid is 1 + 4 = 5 square inches.

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.
5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.
How to verify that RSTU is a trapezoid?In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;
RU ║ ST
Slope of side RU = Slope of side ST
Slope of RU = (y₂ - y₁)/(x₂ - x₁)
Slope of RU = (1 + 3)/(5 + 3)
Slope of RU = 4/8
Slope of RU = 0.5.
Slope of RS = (y₂ - y₁)/(x₂ - x₁)
Slope of RS = (-9 + 3)/(-4 + 3)
Slope of RS = -6/-1
Slope of RS = 6.
Slope of ST = (y₂ - y₁)/(x₂ - x₁)
Slope of ST = (-2 - 1)/(10 - 5)
Slope of ST = -3/5
Slope of ST = -0.6.
Slope of UT = (y₂ - y₁)/(x₂ - x₁)
Slope of UT = (-2 + 9)/(10 + 4)
Slope of UT = 7/14
Slope of UT = 0.5.
Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.
Question 5.
In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance RT = √[(-2 + 3)² + (10 + 3)²]
Distance RT = √170 units.
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance US = √[(5 + 4)² + (1 + 9)²]
Distance US = √181 units.
Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.

WINGSUIT A wingsuit flyer jumps off a tall cliff. He falls freely for a few seconds before deploying the wingsuit and -4.9x² +420, where y is = slowing his descent. His height during the freefall can be modeled by the function y the height above the ground in meters and x is the time in seconds. After deploying the wingsuit, the flyer's height is given by the function y = −3x + 200. deploy the wingsuit?
The total height of the flyer at any time after deploying the wingsuit would be;
y = -3x + 200 + (-4.9t² + 420),
Now, Based on the given information, we can use the two functions to determine the height of the wingsuit flyer at a particular time.
During the freefall, the height of the flyer can be calculated using the function
y = -4.9x² + 420.
Let's say the flyer falls freely for t seconds before deploying the wingsuit.
Therefore, the height at the moment of deploying the wingsuit would be,
y = -4.9t² + 420.
After deploying the wingsuit, the height of the flyer is given by the function
y = -3x + 200.
We can combine these two functions to get the total height of the flyer at any given time after deploying the wingsuit.
So, the total height of the flyer at any time after deploying the wingsuit would be;
y = -3x + 200 + (-4.9t² + 420),
where x is the time after deploying the wingsuit and t is the time of freefall before deploying the wingsuit.

The fraction represented by the point between 1 and 2 on the number line is 5/3.
If the point is between 1 and 2 on the number line, we can determine the fraction it represents by considering the distance between the point and the two adjacent integers.
The point A lies between the numbers 1 and 2, which indicates that the whole number part of the fraction is 1.
Also note that the segment between 1 and 2 is divided into 3 equal parts. A lies on the 2nd part, which implies that the fractional part is 2/3.
