Answer: equation is
c(x)=(10/3)x
54 mints per box
Step-by-step explanation: ok so 3 mints=10 calories
if you input 3 for number of mints, ou get 10 for caloires
10=k3
divide both sides by 3
10/3=k
therfor
C(x)=(10/3)x
full box =180 caloies
therefor
full=180=(10/3)x
multiplyboth sides by 3/10 to clear fraction (since 10/3 times 3/10=30/30=1)
540/10=x
54=x

The math department is putting together an order for new calculators. The
students are asked what model and color they prefer.
Which statement about the students' preferences is true?
The statement (D) "the fewest students prefer black Model A1 calculators" is correct.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.
There is the fewest value is 0.05
More students prefer Model C3 calculators than Model A1 calculators, mathematically,
0.30 > 0.45 (false)
More students prefer black calculators than white calculators, mathematically,
0.35 > 0.65 (false)
Similarly, statement third is also false.
Thus, the statement (D) “the fewest students prefer black Model A1 calculators” is correct.

Which equation represents a line which is parallel to the line y=7/2x-4
Answer:
y=-(7)/(2)x-5
Step-by-step explanation:
to make a parallel equation, you must make an equation that has the same slope, but different b intercepts. so, the equation must have 7/2x, and the b part can be any number.
Answer:
y = 7/2x + 2
Step-by-step explanation:
to make a parallel equation, you must make an equation that has the same slope, but different b intercepts. so, the equation must have 7/2x, and the b part can be any number.
Which equation shows the quadratic formula used correctly to solve 7x^2 = 9 + x for x?
Answer:
Step-by-step explanation:
We must rewrite 7x^2 = 9 + x in standard form first: 7x^2 - x - 9 = 0.
The coefficients are 7, -1 and -9, and so the discriminant b^2 - 4ac is
(1)^2 - 4(7)(-9) = 253.
The roots are:
-(-1) ± √253 1 ± √253
x = --------------------- = --------------------

70% of the magic tricks that Jade knows are card tricks. If she knows 14 card tricks, how many magic tricks does Jade know in all?
Answer:
20
Step-by-step explanation:
Given data
Let the number of magic tricks be x
we are told that she knows 70% of card trick which is 14 card tricks
hence we have
70/100*x= 14
0.7x= 14
x= 14/0.7
x=20
Hence the number of magic tricks she knows is 20

Shana plans to borrow $1,300 to buy a guitar. One bank is offering a simple interest rate of 5% per year on borrowed amounts. Another bank is offering a simple interest rate of 4%. Shana plans to repay the loan in 3 years. In dollars, how much can she save by borrowing from the bank with the lower interest rate? Record your answer in the box.
Answer:
5% times 3=15%
4% times 3=12%
15-12=3
1300 times 0.03= $39

Answer:
radius = 7.5 cm
Step-by-step explanation:
Since M is the midpoint of the chord AB then OM is perpendicular to AB
Using Pythagoras' identity in right triangle OMB with hypotenuse OB, the radius of the circle, then
OB² = OM² + MB² = 4.5² + 6² = 20.25 + 36 = 56.25 ( take square root of both sides )
OB = radius = [tex]\sqrt{56.25}[/tex] = 7.5

Jameson puts $4,000 in graduation money in an account for 10 years. The interest rate is 4.2%. If he withdraws all of the money after 10 years, how much
does he take out?
Answer:
2,320
Step-by-step explanation:
4.2% gets taken every year and there is 10 year,so 4.2% s uqual to 0.042,so just mutiply 4000 by 0.042 which is 168,then times 168 by 10 which brings you to 1680 and 4000 subtracyed by 1680,which equals 2,320
so if squared by 2 means times the number by itself. would 2 squared of 60 be 120?
What is h?
Im so confused on this question
Answer:
i think h stands for height. I dont see it standing for any thing else
Step-by-step explanation:
P is a prime number.
Show that p²+6 could be either even or odd
p ² + 6 is even if p ² is even (the sum of two even numbers is even), and this happens only if p itself is even, i.e. if p = 2 since 2 is the only even prime.
All other primes p are odd, so p ² would be odd, and adding 6 would not change that (odd + even = odd).

URGENT 30 POINTS An engineer needs to find the length of a beam to support the beam holding the wall. If the two beams are perpendicular to one another, and a=4 m and b=1 m, find z. Give your answer to one decimal place.
The value of z in the given arrangement is 2 m.
What are similar triangles?Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.
Also,
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given that, an engineer needs to find the length of a beam to support the beam holding the wall, the two beams are perpendicular to one another, and a=4 m and b=1 m, we need to find z.
So, here we will use the concept of similar triangles,
According to the definition the corresponding sides are in proportion.
So, we get,
z/a = b/z
z² = 4
z = 2
Hence, the value of z in the given arrangement is 2 m.

surface area =
Answer:94 m^2
Step-by-step explanation:
surface area equation for rectangle is 2*(a*b + a*c + b*c)
where a=4 b=5 and c=3
so substitute in all numbers and get:
Surface Area = 2×(4×5 + 4×3 + 5×3)

Step-by-step explanation:
The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.
First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.
In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.
Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so
V=(1/3)(75/2)*22=275

Find the area of the trapezoid
A. 168 in^2
B. 94.5 ft^2
C. 72 ft^2
D. 84 ft^2
Answer:
D. 84 ft^2
Step-by-step explanation:
Formula for area of a trapezoid:
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
The trapezoid shown has the following dimensions
base 1 = 9ft
base 2 = 12ft
height = 8ft
Using the following information we plug in the values into the formula
[tex]A=\frac{9+12}{2} \\9+12=21\\\frac{21}{2} =10.5\\10.5*8=84[/tex]
Hence, the area of the trapezoid is 84ft² and your answer is D
