Answer:
16 had the cheaper ticket
Step-by-step explanation:
Let the number of 75cents tickets be x
Let the number of $1.25 tickets be y
Since the total tickets is 40, hence;
x+y =40 .... 1
Also if some are sold at 75 cents and the rest at $1.25 with total of $42 earned, then;
0.75x+1.25y = 42... 2
From 1
x = 40-y
Substitute into 2;
0.75(40-y)+1.25y = 42
30-0.75y+1.25y = 42
30+0.5y = 42
0.5y =42-30
0.5y = 12
y = 12/0.5
y = 24
Since x = 40-y
x = 40-24
x = 16
The number of cheaper ticket are 16

Ai Mi went to the store to buy some chicken. The price per pound of the chicken is $3.50 per pound and she has a coupon for $2.50 off the final amount. With the coupon, how much would Ai Mi have to pay to buy 3 pounds of chicken? Also, write an expression for the cost to buy pp pounds of chicken, assuming at least one pound is purchased.
Answer:
$8 for 3 pounds
cost for p pounds: 3.50p - 2.50
Step-by-step explanation:
Cost of 3 pounds:
Original cost = Cost per pound x 3
= 3.50 x 3
= 10.50
Coupon = 2.50
Final cost = Original cost - Coupon
= 10.50 - 2.50
= $8
Cost of p pounds:
Original cost = Cost per pound x p
= 3.50 x p
= 3.50p
Coupon = 2.50
Final Cost = Original Cost - Coupon
= 3.50p - 2.50
Ai Mi has to pay $8 to buy 3 pounds of chicken. An expression for the cost to buy p pounds of chicken would be; 3.50p - 2.50
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
The Cost of 3 pounds:
Thus Original cost = Cost per pound x 3
= 3.50 x 3
= 10.50
Also, we know that the Coupon cost is 2.50
The Final cost = Original cost - Coupon
= 10.50 - 2.50
= $8
Now Let the Cost of pounds is p
The Original cost = Cost per pound x p
= 3.50 x p
= 3.50p
Also the cost of the Coupon = 2.50
The Final Cost = Original Cost - Coupon
= 3.50p - 2.50
Hence, Ai Mi has to pay $8 to buy 3 pounds of chicken. An expression for the cost to buy p pounds of chicken would be; 3.50p - 2.50

A 108 mm
B 217 mm
C 454 mm
D 880 mm
Pls show work I really need help
Answer:
A 108 mm
Step-by-step explanation:
The computation is shown below:
As we know that
V = Bh
where
B denotes the area of the base
and h denotes the height of the prism.
Now
V = (1 ÷ 2 × 12.6 × 1.6) × 10.75
= 108.36 mm
= 108 mm

x² = 7225 - 7056 = 169
x = 13
Answer:
x = √(85²-84²)
x = √(7225-7056)

The measures of three angles of a triangle are given by (8x - 5), (2x)º, and (3x – 10). What is the measure of the largest angle? A 15° B 115° C. 35° D 150°
Answer: 115°
Step-by-step explanation:
We should note that the sum of the angles that are in a triangle is equal to 180°, therefore we will add the angles given and equate them to 180°. This will be:
(8x - 5) + (2x) + (3x - 10) = 180
8x - 5 + 2x + 3x - 10 = 180
Collect like terms
8x + 2x + 3x = 180 + 5 + 10
13x = 195
x = 195/13
x = 15
The angles are:
8x - 5 = 8(15) - 5 = 120 - 5 = 115°
2x = 2(15) = 30°
3x - 10 = 3(15) - 10 = 45 - 10 = 35°
Therefore, the largest angle is 115°

Find f(-5) if f(x) = 5x + 11.
A) 4
B) 5
C) 6
Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)
by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.
Now just simplify the right side to get -25 + 11 or -14.
So f(-5) = -14.

What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔXYZ
And , the measures of the sides of the triangle are
z = 75 inches
x = 26 inches
And , the measure of ∠Y = 135°
We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.
The Law of Cosines states that:
c² = a² + b² - 2ab cos(C)
where c is the side opposite angle C, and a and b are the other two sides.
In this case, we want to find the length of side y, which is opposite angle Y. So we can write:
y² = x² + z² - 2xz cos(Y)
Substituting in the given values, we get:
y² = 26² + 75² + 2(26)(75) cos(135°)
Simplifying, we get:
y² = 676 + 5625 - 2925√2
y² ≈ 9163
Taking the square root of both sides, we get:
y ≈ 95.76
Rounding to the nearest inch, we get:
y ≈ 96 inches
Hence , the length of y, to the nearest inch, is 96 inches
