Answer: 88 cones.
Step-by-step explanation:
We know that:
price of a cone = $1.10
price of a sundae = $2.35
A total of 172 cones and sundaes were sold for $294.20
Then we can define two variables:
C = number of cones sold
S = number of sundaes sold.
C + S = 172 (the total number of sundaes and cones sold is 172)
C*$1.10 + S*$2.35 = $294.20 (that is how much the won).
Then we have the system of equations:
C + S = 172
C*$1.10 + S*$2.35 = $294.20
And we want to find how many cones were sold.
To solve this, we first need to isolate the other variable, S, in one of the equations, i will isolate S in the first equation:
S = 172 - C
Now, let's replace this in the second equation:
C*$1.10 + (172 - C)*$2.35 = $294.20
Now we can solve this for C, and find the number of cones that were sold.
C*$1.10 + $404.20 - C*$2.35 = $294.20
C*($1.10 - $2.35) = $294.20 - $404.20
-C*1.25 = -110
C = 110/1.25 = 88
88 cones were sold.

Anyone know how to find the missing length ?
Answer:
so i'm assuming you'd use Pythagoras:
so 15^2-12^2=81
square root it=9 which is I
to find T we do 41^2-9^2=1600
square root that is 40 so T=40
Find x and y. Give reasons to justify your solution
Answer:
Y=21
X=8
Step-by-step explanation:
In the middle there is a right angle
therefore 27 +3y=90
Y will be 21
Then x+27+63+8x+18=180
x=8
Hence 8+27+3(21)+8(8)+18=180
Step-by-step explanation:
27 + 3y = 90
3y = 90 - 27
y = 21
27 + (21×3) + x + 8x + 18 = 180 ( angles on a straight line sum up to 180)
9x + 108 = 180
9x = 180 - 108
9x = 72
x = 72/9
x = 8 degrees

The Umbrella Corporation has found that in any given month, they sell fewer umbrella when the cost of the umbrella is higher. When the price of the umbrella is $10, they sell on average 18,000 umbrellas. When the price of the umbrellas is $16, they sell on average 9,000 umbrellas.
(a) Write a linear function U(p) that predicts the number of umbrellas sold based on the price p.
(b) How many umbrellas do they expect to sell if they raise the price to $20?
Answer:
The answer is below
Step-by-step explanation:
a) A linear function shows the relationship between variables. A linear equation is in the form: y = mx + b, where m is the rate of change, b is the value of y when x = 0, y is the dependent variable and x is an independent variable.
Let U represent the number of umbrellas and p the price of the umbrella. At $10 the number of umbrella sold is 18000, it can be represented as (10, 18000) i.e. (p, U)
At $16 the number of umbrella sold is 9000, it can be represented as (16, 9000).
The linear function is determined using:
[tex]U-U_1=\frac{U_2-U_1}{p_2-p_1}(p-p_1)[/tex]
Given (10, 18000) and (16, 9000):
[tex]U-U_1=\frac{U_2-U_1}{p_2-p_1}(p-p_1)\\\\U-18000=\frac{9000-18000}{16-10}(p-10)\\\\U-18000=-1500(p-10)\\\\U-18000=-1500p+15000\\\\U=-1500p+15000+18000\\\\U=-1500p+33000\\\\U(p)=-1500p+33000[/tex]
b) At p = $20, The number of umbrella is:
U(20) = -1500(20)+33000
U(20) = 3000 umbrella

A auto manufacturer claims that one of its car brands has mean MPG (miles per gallon) rating of 40 on the highway. Identify Type I error for this claim.
a. Fail to reject the claim that mean is 40 MPG when it is actually 40 MPG.
b. Fail to reject the claim that mean is 40 MPG when it is actually not 40 MPG.
c. Reject the claim that mean is 40 MPG when it is actually not 40 MPG.
d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.
Answer:
d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.
Step-by-step explanation:
The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.
In the scenario above :
The null hypothesis (H0) : mean = 40
Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.
On the other hand, the type 2 error occurs when a null which is false is not rejected.
Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.

Solve the equation 5(2x -3) = 15
Answer:
x=3
Step-by-step explanation:
5(2x-3)=15
10x-15=15
10x=30
x=3
Answer:
x=3
Step-by-step explanation:
5(2x -3) = 15
10x-15=15
10x-15+15=15+15
10x=30
To find the x divide 10 to 30 so that is why 30÷10=3.

What is the greatest common factor of 24 and 48?
Answer:
Greatest Common Factor: 24
Step-by-step explanation:
The greatest common factor is found by multiplying all the factors which appear in both lists: So the GCF of 24 (2x2x2x3) and 48 (2x2x2x2x3) is 2x2x2x3 which is 24.
The greatest common factor of 24 and 48 is 24.
Here, we have,
To find the greatest common factor (GCF) of 24 and 48,
we can use the prime factorization method:
Step 1: Find the prime factorization of each number.
Prime factorization of 24:
24 = 2 * 2 * 2 * 3
Prime factorization of 48:
48 = 2 * 2 * 2 * 2 * 3
Step 2: Identify the common prime factors and their lowest exponents.
Common prime factors: 2 * 2 * 2 * 3
Step 3: Multiply the common prime factors with their lowest exponents.
GCF(24, 48) = 2 * 2 * 2 * 3 = 24
So, the greatest common factor of 24 and 48 is 24.

Find a polynomial of degree 3 with real coefficients and zeros of -3,-1, and 4, for which f(-2)=-24
We want to find a polynomial
f(x) = a x³ + b x² + c x + d
such that the roots of f are x = -3, x = -1, and x = 4, and f(x) takes on a value of -24 when x = -2.
The factor theorem for polynomials tells us that we can factorize f(x) as
a x³ + b x² + c x + d = a (x + 3) (x + 1) (x - 4)
Expand the right side:
(x + 3) (x + 1) (x - 4) = x³ - 13x - 12
So we have
a x³ + b x² + c x + d = a x³ - 13a x - 12a
In order for both sides to be equal, the coefficients of both polynomials on terms of the same degree must be equal. This means
a = a (of course)
b = 0 (there is no x² term on the right)
c = -13a
d = -12a
We also have that f (-2) = -24, which means
f (-2) = a (-2 + 3) (-2 + 1) (-2 - 4)
-24 = 6a
a = -4
which in turn tells us that c = 52 and d = 48.
So we found
f(x) = -4x³ + 52x + 48
