Mary buys 8 cupcakes for $6 and Pete buys 12 cupcakes for $9. Who got the better deal PER cupcake or did they spend the same amount per cupcake?
Answers
Answer:
Step-by-step explanation:
Mary spends 8*6=48 dollars
Pete spends 9*12=108
Mary got a better deal per cupcake
Answer:
They spent the same amount per cupcake ($1.33)
Step-by-step explanation:
To solve this, we need to find the unit rate of cost per cupcake. To do that, we divide 8 by 6 and divide 12 by 9. When we do that, we get 1.33 for both. That means they spent the same amount per cupcake ($1.33).

Answers
Answer:
3
Step-by-step explanation:
Given that:
Integers : x, x + 1, x + 2
6x - 2(x + 1) = (x+2) + 5
6x - 2x - 2 = x + 2 + 5
4x - 2 = x + 7
4x - x = 7 + 2
3x = 9
x = 9/3
x = 3
First integer = x = 3
2nd integer = x + 1 = 3+1 = 4
3rd Integer = x + 1 + 1 = 3 + 2 = 5

If a right hexagonal prism became an oblique hexagonal prism, would that have any effect on the volume and height of the
solid? Explain your answer.
Answers
Answer:
Even if a right solid became oblique, the volume would not change, because the cross sectional area and height would remain the same. Therefore, by Cavalieri's principle, the volume is the same as the original solid.

A Boat is tied to the dock with a 25-foot rope. When the rope is pulled tight, the boat is 18 feet away from the base of the dock. The rope connects to the boat at the level of the water. What is the measure, to the nearest tenth of a degree, of x, the angle formed by the rope and the surface of the water?
Answers
Answer:
43.9°
Step-by-step explanation:
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
From the question
Adjacent = Distance of the boat from the dock = 18 feet
Hypotenuse = Length of the rope = 25 feet
The angle formed by the rope and the surface of the water = x
Hence:
cos x = 18/25
x = arc cos (18/25)
x = 43.945519562°
Approximately θ = 43.9°
The angle formed by the rope and the surface of the water is given as 43.9°

Answer:
∠ 1 = 110°, ∠ 2 = 70°
Step-by-step explanation:
∠ 1 and 110° are vertical angles and are congruent, thus
∠ 1 = 110°
∠ 1 and ∠ 2 are same- side interior angles and supplementary, sum to 180°
∠ 1 + ∠ 2 = 180°
110° + ∠ 2 = 180° ( subtract 110° from both sides )
∠ 2 = 70°

Find the lcm of 5m^7+ 35m^6+50m^5 And -20m^5-80m^4+100^3
Answers
Answer:
LCM of both polynomials=[tex]\mathbf{5m^3}[/tex]
Step-by-step explanation:
Least Common Multiple
We are given the polynomials
[tex]5m^7+ 35m^6+50m^5[/tex]
[tex]-20m^5-80m^4+100m^3[/tex]
Find the common factors of each polynomial, first the coefficients:
5 = 5
35 = 5*7
50 = 5*5*2
The common factor with the least exponent; 5
Now for the variables:
[tex]m^7, m^6, m^5[/tex]
The common factor with the least exponent; m^5
LCM of [tex]5m^7+ 35m^6+50m^5: 5m^5[/tex]
Similarly:
20 = 2*2*5
80=2*2*2*2*5
100 = 2*2*5*5
Common factor of the coefficients: 2*2*5=20
Common factor of variables: [tex]m^3[/tex]
LCM of [tex]-20m^5-80m^4+100m^3 = 20m^3[/tex]
LCM of both polynomials=[tex]\mathbf{5m^3}[/tex]

Answers
Answer:
-3 and 17
Step-by-step explanation:
Let the number be = x
x - 7 = -10
x = -10 + 7
x = -3
OR
7 - x = -10
- x = -10 - 7
- x = -17
x = -17/-1
x = 17
The two possible numbers are -3 and 17
