We have two stacks of styrofoam cups. One stack has 6 cups, and its height is 15 cm. The other stack has 12 cups, and its height is 23 cm. How many cups are needed for a stack with a height of 50 cm
Answer:
37.5 cups
Step-by-step explanation:
Height 1 = 15cm
Number of cups = 6
Height 2 = 23 cm
Number of cups = 12
Hence:
H1 - H2/N1 - N2
= 15 - 23/6 - 12
= -8/-6
= 4/3
The number of cups that are needed for a stack with a height of 50 cm is calculated as:
50 cm ÷ 4/3
= 50 × 3/4
= 37.5 cups

The office supply superstore sells pens for 60 cents each and
pencils for 40 cents each. Diane purchased a total of 17 items
(pens and pencils) for $8.20. How many pens did Diane
purchase?
A 5
В 7
C 10
D
12
Answer:
Option B. 7
Step-by-step explanation:
In order to solve this question we first have to find out what is the difference between the prices of a pen and a pencil. SO we get...
60 - 4- = 20 cents
Now if we were to assume that all 17 items were pencils then Diane would pay....
17 x 0.40 = $6.8
But then he pays 8.2-6.8 = $1.4 less than he should be.
If we substitute one pencil with a pen the total will increase by 20 cents. From here we can easily get the number of pens by doing the following...
1.4 / 0.2 = 7 pens
Therefore option B is the right answer.
Diane purchased 7 pens and 10 pencils.
The selling price of pens is 60 cents each ($0.6) while it is 40 cents each for pencils ($0.4).
Let x represent the number of pens bought and y represent the number of pencils.
Since a total of 17 items was bought for $8.20, hence:
x + y = 17 (1)
0.6x + 0.4y = 8.2 (2)
Solving equations 1 and 2 gives:
x = 7, y = 10
Therefore Diane purchased 7 pens and 10 pencils.

Henry is going to invest in an account paying an interest rate of 2.5% compounded continuously. How much would henry need to invest for the value of the account to reach $690 in 6 years?
Answer:
$595.34
Step-by-step explanation:
Step one
given data
interest rate of 2.5%= 0.025
final amount= $690
time = 6 years
Required
Principal P
Step two
The compound interest formula is
[tex]A= P(1+r)^t[/tex]
substitute
[tex]690=P(1+0.025)^6\\\\690=P(1.025)^6\\\\690=P1.159\\\\[/tex]

10 A solid metallic cylinder of radius 14 cm and
height 21 cm is melted and recast into equal
small spheres each of radius 7/2 cm. Find then
number of spheres formed.
Answer:
72 spheres are formed
Step-by-step explanation:
We start by calculating the volume of the metallic cylinder
Mathematically, we have this as;
V = pi * r^2 * h
V = pi * 21 * 14^2
V = 4116 π cm^3
The volume of each small sphere is;
V = 4/3 * pi * r^3
= 4/3 * π * 7/2^3 = 57.167 π cm^3
To get the number of small spheres, we simply divide the volumes
That will be 4116 pi / 57.167 pi = 72
If the measure of Angle B E C is (2 x + 3) degrees and x = 30, which expression could represent the measure of Angle A E D?
Lines A C and B D intersect at point E.
(4 x minus 3) degrees
(3 x minus 27) degrees
(5 x minus 33) degrees
(x + 43) degrees
Answer:
(3x−27)o
Step-by-step explanation:
we know that
m\angle BEC=m\angle AEDm∠BEC=m∠AED ----> by vertical angles
we have
m\angle BEC=(2x+3)^om∠BEC=(2x+3)o
The value of x is given
x=30
so
m\angle BEC=(2(30)+3)=63^om∠BEC=(2(30)+3)=63o
That means that the measure of angle AED is also 63 degrees
so
The expression that could represent the measure of Angle A E D is
(3x-27)^o(3x−27)o
because
For x=30
(3(30)-27)=63^o(3(30)−27)=63o
Answer:
(3x−27)o

Use the quadratic formula to solve the equation. –x2 + 7x = 8
Answer:
The solutions are:
[tex]x=\frac{7-\sqrt{17}}{2},\:x=\frac{7+\sqrt{17}}{2}[/tex]
Step-by-step explanation:
Given the quadratic equation
-x² + 7x = 8
Solving using the quadratic formula
[tex]-x^2+7x=8[/tex]
Subtract 8 from both sides
[tex]-x^2+7x-8=8-8[/tex]
Simplify
[tex]-x^2+7x-8=0[/tex]
For a quadratic function of the form ax² + bx + c = 0, the solutions are:
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
For a = -1, b = 7, c = -8
[tex]x_{1,\:2}=\frac{-7\pm \sqrt{7^2-4\left(-1\right)\left(-8\right)}}{2\left(-1\right)}[/tex]
[tex]x_{1,\:2}=\frac{-7\pm \:\sqrt{49-32}}{2\left(-1\right)}[/tex]
[tex]x_{1,\:2}=\frac{-7\pm \sqrt{17}}{2\left(-1\right)}[/tex]
Separate the solutions
[tex]x_1=\frac{-7+\sqrt{17}}{2\left(-1\right)},\:x_2=\frac{-7-\sqrt{17}}{2\left(-1\right)}v[/tex]
solving
[tex]x_1=\frac{-7+\sqrt{17}}{2\left(-1\right)}[/tex]
[tex]=\frac{-7+\sqrt{17}}{-2}[/tex]
Apply the fraction rule: [tex]\frac{-a}{-b}=\frac{a}{b}[/tex]
i.e. [tex]-7+\sqrt{17}=-\left(7-\sqrt{17}\right)[/tex]
so
[tex]=\frac{7-\sqrt{17}}{2}[/tex]
Similarly solving
[tex]x_2=\frac{-7-\sqrt{17}}{2\left(-1\right)}[/tex]
[tex]=\frac{-7-\sqrt{17}}{-2\cdot \:1}[/tex]
Apply the fraction rule: [tex]\frac{-a}{-b}=\frac{a}{b}[/tex]
i.e. [tex]-7-\sqrt{17}=-\left(7+ \sqrt{17}\right)[/tex]
[tex]=\frac{7+\sqrt{17}}{2}[/tex]
Therefore, the solutions are:
[tex]x=\frac{7-\sqrt{17}}{2},\:x=\frac{7+\sqrt{17}}{2}[/tex]
