The Kendall family was preparing to go hiking with the Smith family. In preparation,
the Kendall's bought 8 Cliff Bars and 4 appleslfor $12.40. The Smith family spent
$24.30 on 15 Cliff Bars and 9 apples. What is the difference in price between a cliff
bar and an apple?
Answer:$9.3 is the bars and the rest is the apples
Step-by-step explanation:because you take away from the bars than what is left is the apples.
The difference in price between a cliff bar and an apple is $0.50.
To determine the difference in price between a cliff bar and an apple, we must create two equations based on the information provided:
8C + 4A = 12.40 (equation 1 for the Kendall family)
15C + 9A = 24.30 (equation 2 for the Smith family)
We can solve these equations using substitution or elimination. Let's use the elimination method:
Multiply equation 1 by 2 to get 16C + 8A = 24.80 (equation 3).
Subtract equation 3 from equation 2: (15C + 9A) - (16C + 8A) = 24.30 - 24.80 which gives us -C + A = -0.50.
From this simplified equation, we gather that the price difference between a cliff bar and an apple is $0.50.
Therefore, the difference in price between a cliff bar and an apple is $0.50.
Solve 2y+1−x=7x for y
Answer:
Y=4X-1/2
Step-by-step explanation:
You must isolate the variable by dividing each side by factors that dont contain variables.
Answer:
y = 4x - 1/2
Step-by-step explanation:
2y + 1 − x = 7x
2y = 7x + x - 1
2y = 8x - 1
y = (8x - 1)/2
y = 4x - 1/2

After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are A'(6,3), B'(-2, 1)
and C'(1,7). What are the coordinates of the vertices of the pre-image?
С.
Answer:
A(3, -6)B(1, 2)C(7, -1)Step-by-step explanation:
Rotation by -90° about the origin is the transformation ...
(x, y) ⇒ (y, -x)
So, your pre-image points are ...
A'(6, 3) ⇒ A(3, -6)
B'(-2, 1) ⇒ B(1, 2)
C'(1, 7) ⇒ C(7, -1)
Which of these defines the longest arc?
Answer: C
Step-by-step explanation:
The arc length, s, equals the radius, r, times the central angle, θ, given in radians. (In shorthand, s=r⋅θ.) If r=5 cm and θ=6 radians, the arc length is 5 cm⋅6=30 cm. If r=7 cm and θ=5 radians, the arc length is 7 cm⋅5=35 cm. If r=9 cm and θ=4 radians, the arc length is 9 cm⋅4=36 cm. An angle of 180∘ is π radians, or about 3.14. If r=10 cm, the arc length is 10 cm⋅3.14=31.4 cm. Of these choices, the longest arc is 36 cm.

Elian won a sweepstakes and will receive money every week for 52 weeks. The first week, he will receive $500. Every week after that, he will receive $50 more than he received the previous week.
The amounts of money Elian receives each week form an arithmetic sequence. What is the explicit formula for the sequence?
The answer needs to be in simplified form.
Here is the explicit formula for the arithmetic sequence: an = 500 + 50(n - 1)
What does the explicit formula mean?where:
an is the amount of money Elian receives in week n
500 is the first payment
50 is the common difference
n is the week number (1-indexed)
For example, in week 2, Elian will receive $550 because 500+50(2−1)=550.
The formula is in simplified form because the common difference is a simple integer

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 85% pure antifreeze. The company wants to obtain 255 gallons of a mixture that contains 60% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answer:
75 gallons of water
180 gallons of premium anti-freeze
Step-by-step explanation:
X + Y = 255
X = 255 - Y
0.85Y = 0.6(255)
0.85Y = 153
Y = 180
X = 255 - 180
X = 75
After being marked up 40%, the sale price of a tennis racket is $87.50 What was the original price of the tennis racket?
Answer:
$62.50
Step-by-step explanation:
The original price is x
It is marked up 40 percent
x+.40x = new price
1.40x = new price
The new price is 87.50
1.40x = 87.50
Divide each side by 1.40
1.40x/1.40 = 87.50/1.40
x =62.50
The price before mark up is 62.50
Answer:
$62.50
Step-by-step explanation:
After mark up, price is
100 + 40 = 140% of cost
140/100 × Cost = 87.50
Cost = 87.50 × 100/140
Cost = $62.50

Cholula
Step-by-step explanation:
first find the vlumes of the different pyramids:
FORMULA:
volume = (1/3) * basearea
Cholula- 157,583,664
Cheops- 91,204,000
Answer:
The Cholula Pyramid has a greater volume.
Step-by-step explanation:
volume = (1/3) * area of base * height
In both cases, the base is a square, so the area of the base is (side)^2
volume = (1/3) * (side)^2 * height
Cholula Pyramid:
volume = (1/3) * (side)^2 * height
volume = (1/3) * (1476 ft)^2 * 217 ft
volume = 157,583,664 ft^3
Cheops Pyramid:
volume = (1/3) * (side)^2 * height
volume = (1/3) * (755 ft)^2 * 480 ft
volume = 91,204,000 ft^3
The Cholula Pyramid has a greater volume.
What is the radius of a great circle with an area of 40 in??
Round to the nearest tenth.
Answer:
3.6
Step-by-step explanation:
If the sphere has a volume of approximately 904.78 cm3, what is the approximate area of the largest cross-section of the sphere shown? A) 28.27 cm2 B) 113.1 cm2 C) 226.2 cm2 D) 452.39 cm
Final answer:
Given a sphere with a volume of 904.78 cm3, we find the radius to be approximately 6.13 cm, and the area of the largest cross-section, a circle, turns out to be approximately 118.08 cm2.
Explanation:
If the sphere has a volume of approximately 904.78 cm3, we can start by calculating the radius of the sphere using the volume formula for a sphere:
V = (4/3)πr3
Solving for r:
r = &Sqrt[3]{(3V)/(4π)} = &Sqrt[3]{(3×904.78 cm3)/(4π)} ≈ 6.13 cm
The largest cross-section of the sphere will be a circle with the diameter equal to the diameter of the sphere, hence the area A of this circle will be:
A = πr2 = π×(6.13 cm)2 ≈ 118.08 cm2
Therefore, the approximate area of the largest cross-section of the sphere is 118.08 cm2, which is not listed among the provided options, implying a possible typo or error in the options. Option closest to the calculated area is B) 113.1 cm2.

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5.
In other words, an equation is a set of variables that are constrained through a situation or case.
To form an equation we must know the constraint of that condition,
For example x < 5 is a constraint.
Another example of a constraint is;
7x + 3y = 8 like that
Let say
Your age is = x
21 year ago your age were = x - 21
Now it was half the age x so,
x - 21 = (1/2)x
2x - 42 = x
x = 42
So your current age will be 42 years old.

Choices:
(A) 5.6
(B) 8.75
(C) 11
(D) 15
Answer:
TS = 11.
Step-by-step explanation:
Consider triangles UTO and UCS.
m < C = m < UTO (Given)
< U is common to both triangles.
Therefore triangles UTO and OCS are similar.
So corresponding sides are in the same ratio and:
5 / (TS + 4) = 4/ (7+5)
5 * (7 + 5) = 4(TS + 4)
TS + 4 = 5*12 / 4
TS + 4 = 15
TS = 11.
