A heap of grain is shaped as a cone ADCF with height 5 m and base radius 2 m, as shown on the diagram. A and C are points on the circumference of the circular base of the cone and = 120°. Find:
a. the angle between [A F] and the base of the cone
Answer:
The angle between [A_F] and the base of the cone = 68.2°
The area of the base of the cone ≈ 12.57 m²
Step-by-step explanation:
The given parameters are;
The height of the cone = 5 m
The base radius of the cone = 2 m
The angle which the A[tex]\hat O[/tex]C = 120°
Therefore, we have;
The angle between [A_F] and the base of the cone = The angle between [CF] and the base of the cone
The angle between [CF] and the base of the cone = tan⁻¹(5/2) = tan⁻¹(2.5) ≈ 68.2°
∴ The angle between [A_F] and the base of the cone = The angle between [CF] and the base of the cone = 68.2°
The angle between [A_F] and the base of the cone = 68.2°
The area of the base of the cone = π × r² = π × 2² = 4·π ≈ 12.57
The area of the base of the cone ≈ 12.57 m².

(FORMULA: Surface Area = 2lw + 2lh + 2wh) Which statement about Kali's tiles is true? Group of answer choices Kali needs 476 more tiles to completely cover the box. Kali needs 104 more tiles to completely cover the box. Kali will have 534 tiles left after completely covering the box. Kali will have 250 tiles left after comp
Answer:
Kali needs 104 more tiles to completely cover the box.
Step-by-step explanation:
Length of box = 20 in
Breadth of box = 6 in
Height of box= 9 in
Total surface area of box = 2lw + 2lh + 2wh
Total surface area of box = 2(20)(6) + 2(20)(9) + 2(6)(9)
Total surface area of box = 708 sq. in.
Side of tile = 1 in
Area of 1 tile = [tex]Side^2 = 1^2 = 1 sq. in[/tex]
Area of 604 tiles = 604 sq. in.
Area remain uncovered = 708 - 604 = 104 sq.in.
So, Kali needs 104 more tiles to completely cover the box.

For a school fund-raiser, students sold T-shirts with the school logo for $14. PLEASE HELP!
They sold sweatshirts with the school logo for $20.
They sold 233 pieces of clothing and raised $3,748.
How many of each type of shirt did they sell at the fund-raiser?
Let x = the number of T-shirts sold.
Let y = the number of sweatshirts sold.
Answer:
The 3 problem
Step-by-step explanation:
Answer:
The answer is C) x+y = 233, 14x + 20y = 3748
Step-by-step explanation:
x(number of t-shirts sold) + y(number of sweatshirts sold) = 233 (total number of pieces of clothing sold)
14x (14 is the cost of each t-shirt and since x = number of t-shirts sold then it is 14x or 14 multiplied by number of t-shirts sold) + 20y (20 is the cost of each sweatshirt and since y = number of sweatshirts sold then it is 20y or 20 multiplied by number of sweatshirts sold) = 3748 (total of money raised)

Which points lie on the line y= -1/2x +4?
A) (-2,5) and (2,3)
B) (0,6) and (1,4)
C) (-2,5) and (4,3)
D) (-2,3) and (0,2)
Which answer choice is the equation of a line that passes through the points (1.-3) and (-1,3)? A) y = -1/3
B) -3y = x + 1
C) y = 3x
4) 3x + y = 0
Question #1
first, you need to find the slope. Use the formula: m=(y₂-y₁)/(X₂-X₁). Plug in x and y values. once you have found the slope, use point-slope form;
(y-y₁)=m(x-x₁). Again, plug in x and y values. Simplify the equation. Do that with the coordinate pairs, to see which one matches y=-1/2x+4. The answer though is A, (-2,5) and (2,3).
Question #2
Do the same thing, find the slope using the formula, and then use point-slope form. After that, find the matching equation and that's the answer. I am confused though because the right equation would be [tex]y=-3x[/tex], but that's not one of the answers.

Answer:
As an equation: 15 × x = -75
Solved: x = -5
Step-by-step explanation:
15*x = -75
[tex]\frac{15*x}{15}[/tex] = [tex]-\frac{75}{15}[/tex], Divide by 15 on both sides to solve for x
x=[tex]-\frac{75}{15}[/tex], The 15 in the numerator cancels out with the denominator

Kiera and Trina joined a gym. The gym offers two different payment plans. Kiera chose Plan 1 and pays $25 a month and no fee to join. Trina chose Plan 2 and pays $10 a month, plus a $100 joining fee. Which equation models Kiera’s total payments, t1, and Trina’s total payments, t2, after m months?
Answer:
t1 = $25m
t2 = $(10m + 100)
Step-by-step explanation:
Here we want to write equations
Kiera chose plan 1
$25 monthly and no joining fee
So the amount after m months will be 25 * m
t1 = $25m
Trina chose plan 2
$10 a month and $100 joining fee
after m months , total payment will be
10(m) + 100 = $(10m + 100)
Thus t1 = $25m and t2 = $(10m + 100)
Solve the system of equations by substitution. x + y = 27 y = 8x
Answer: x = 0, y = 0
Step-by-step explanation:
x + y = 27y = 8x
Consider the first equation. Subtract 27y from both sides.
x + y = -27y = 0
Combine y and -27y to get -26y
x - 26x = 0
Consider the second equation. Subtract 8x from both sides.
27y - 8x = 0
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for the variable in the other equation.
x - 26y = 0, -8x + 27y = 0
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
x - 26y = 0
Add 26y to both sides of the equation.
x = 26y
Substitute 26y for x in the order equation,
-8x + 27y = 0.
-8 x 26y + 27y = 0
Multiply -8 times 26y
-208y + 27y = 0
Add -208y to 27y
-181y = 0
Divide both sides by -181.
y = 0
Substitute 0 for y in x = 26y. Because the resulting equation contains only one variable, you can solve for x directly.
x = 0
