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?
Answers
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.

R(5, 15). Find the length of the perpendicular
from Q to PR.
Answers
The distance of the perpendicular from Q to line PR is D = 2.2135 units
Given data ,
Let the triangle be represented as ΔPQR
Now , the coordinates are P(1, 3), Q(5, 4) and R(5, 15)
And , the equation of line of PR is given by
Slope m = ( 15 - 3 ) / ( 5 - 1 )
m = 3
y - 3 = 3 ( x - 1 )
Adding 3 on both sides , we get
y = 3x
y - 3x = 0
And , the point is Q(5, 4)
Now , distance of a point to line D = | Ax₀ + By₀ + C | / √ ( A² + B² )
D = | ( 1 ) ( 5 ) + ( -3 ) ( 4 ) + 0 | / √ ( 1 )² + ( 3 )²
D = | 5 - 12 | / √10
D = 7/√10
D = 2.2135 units
Hence , the distance is 2.2135 units

; (ii)how many students study (a) only French (b) only one subject;(c) neither Arabic nor French.
Answers
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

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?
Answers
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.
A 3-D jigsaw puzzle becomes a cube with a volume of 1 cubic foot when it is solved. Mr. Ruiz stores several of these puzzles in a storage nook in his classroom.

Answers
The volume of the storage nook is 24 cubic feet.
How to find the volume of the storage nookTo find the area of 8 puzzles, we multiply the area of one puzzle by 8:
Area of 8 puzzles = 1 square foot * 8 = 8 square feet
Now, to find the volume of the storage nook, we multiply the area of the floor by its height:
Volume of the nook = Area of the floor * Height

The value of a3 in the Arithmetic sequence with a1 = -10 and d = -2 is -14.
The value of a3 in the arithmetic sequence, we can use the formula for the nth term of an arithmetic sequence:

Where:
- an is the nth term in the sequence
- a1 is the first term of the sequence
- d is the common difference between consecutive terms
- n is the position of the term we want to find
In this case, we are given that a1 = -10 and d = -2. We want to find the value of a3, which corresponds to the third term in the sequence (n = 3).
Plugging in the values into the formula, we have:
a3 = a1 + (3 - 1) * d
= -10 + 2 * (-2)

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.
Answers
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.

For positive acute angles A and B, it is known that SinA= 11/61 and tan B=4/3. Find the value of Cos(A-B) in simplest form.
Answers
For positive acute angles A and B, if it is known that SinA= 11/61 and tan B=4/3, cos(A-B) = 224/305.
We can use the trigonometric identity cos(A-B) = cosA cosB + sinA sinB to find the value of cos(A-B).
First, we need to find the value of cosA and sinB:
Since sinA = opposite/hypotenuse, we can draw a right triangle with opposite side 11 and hypotenuse 61, and use the Pythagorean theorem to find the adjacent side:
cosA = adjacent/hypotenuse = √(61² - 11²)/61 = 60/61
Since tanB = opposite/adjacent, we can draw another right triangle with opposite side 4 and adjacent side 3, and use the Pythagorean theorem to find the hypotenuse:
hypotenuse = √(4² + 3²) = 5
sinB = opposite/hypotenuse = 4/5
Now we can substitute these values into the formula:
cos(A-B) = cosA cosB + sinA sinB
= (60/61)(3/5) + (11/61)(4/5)
= 180/305 + 44/305
