Lauren invests money in an accout paying simple interest.She invests $50 and no money is added or removed from investments.After one year she has $50.50.What is the simple percent of interest per year
Answer:
1%
Step-by-step explanation:
\text{\color{blue}{100\%} represents the \color{blue}{starting balance}: \color{blue}{\$50}.}
100% represents the starting balance: $50.
Method 1
Express the ending balance as a percentage of the starting balance:
\frac{\color{darkviolet}{\$50.50}}{\color{blue}{\$50}}=
$50
$50.50
=
\,\,1.01
1.01
1.01\times100=
1.01×100=
\,\,\color{darkviolet}{101\%}
101%
\text{Subtract the starting \color{blue}{100\%} to get the \color{green}{percent interest}:}
Subtract the starting 100% to get the percent interest:
\color{darkviolet}{101\%}-\color{blue}{100\%}=
101%−100%=
\,\,\boxed{\color{green}{1\%}}
1%

The surface area of this cube is 864 square yards. What is the value of q?
Answer:
Volume
=
512
cubic feet
Explanation:
A cube has
6
faces all with equal area.
If the total surface area of the cube is
384
sq.ft.
then each face has an area of
384
÷
6
=
64
sq.ft.
Each face of a cube is a square and if we denote the length of an edge as
E
then the area of a face (in this case
64
sq.ft.) is equal to
E
2
XXX
E
2
=
64
sq.ft.
XXX
→
E
=
8
sq.ft.
The volume of a cube with edges of length
E
is
E
3
In this case
Volume
=
E
3
=
8

=
512
sq.ft.

Find tan (QRS)
Answer:
A. [tex] \frac{\sqrt 3}{3}[/tex]
Step-by-step explanation:
[tex]m\angle QSR = 180\degree - 150\degree \\ (Linear \: pair\: \angle s) \\ \\m\angle QSR = 30\degree \\ \\ \tan( \angle QSR) = \tan \: 30 \degree \\ \\ = \frac{1}{ \sqrt{3} } \\ \\ = \frac{ \sqrt{3} }{3} [/tex]
Answer:
because
TSR + QSR = 180⁰
<=> 150⁰ + QSR = 180⁰
=> QSR = 30⁰
so
[tex] \tan(qsr) = \tan(30) = \frac{ \sqrt{3} }{3} [/tex]
A globe of the moon has a radius of 13 centimeters. Find the volume of the globe. Round your answer to the nearest whole number.
Answer:
9203 cm³
Step-by-step explanation:
A globe of the moon has a radius of 13 centimeters. Find the volume of the globe. Round your answer to the nearest whole number.
The shape of the moon is spherical
Hence:
The volume of a sphere
= 4/3 × π × r³
r = radius = 13 cm
= 4/3 × π × 13³
= 9202.77 cm³
Approximately to the nearest whole number = 9203 cm³
Therefore, the volume of the globe is 9203 cm³

Martin got a haircut yesterday if he pad $27 and left an 18% tip, what was the total bill
======================================================
Work Shown:
x = total bill amount ignoring the tip
18% of x = 0.18x = tip amount
x+0.18x = 1.18x = amount Martin paid = 27
1.18x = 27
x = 27/1.18
x = 22.8813559322033 approximately
x = 22.88 dollars was the total bill.
----------
Checking the answer:
18% of 22.88 = 0.18*22.88 = 4.1184 = 4.12
Martin left a tip of $4.12
Add this on top of the bill to get 22.88+4.12 = 27
This matches with the fact he paid $27.
The answer is confirmed.

Step-by-step explanation:
2x = y-10
Rewrite as: 2x + 10 = y
Therefore:
2x+10 = y
2x +7 = 2y
Subtract the equations:
2x + 10 = y
- 2x + 7 = 2y
______________
3 = -y
Therefore y = -3
Substiture y = -3 into the second equation:
2x + 7 = 2(-3)
2x + 7 = -6
2x = -13
x= -6.5
Answer : (-6.5, -3)
Answer:
(-13/2,-3)
Step-by-step explanation:
First you want to isolate y from 2x=y-10 or 2x+7=2y. In this case, I picked 2x=y-10 so I added 10 on each side to make y=2x+10. Because we know what y is equal to, we have to plug that into the other equation which is 2x+7=2y so the equation will look like 2x+7=2(2x+10). Simplify this to get 2x+7=4x+20. Simplify this again to get 2x=-13. Divide 2 by each side to get x=-13/2. Then, you have to -13/2 back into one of the equations. In this case, I picked 2x+7=2y so the equation will look like this. 2(-13/2)+7=2y. Simplify this to get -13+7=2y. Simplify again to get -6=2y. Simplify this again to get y=-3. Therefore, x=-13/2 and y=-3. To put it in ordered pair form which is (x,y). Plug that in to get (-13/2,-3).

Find the values of a, b, and c for the equation in standard form (y=ax^2+bx+c) of the graph of the parabola shown below.
a =____________
b = ___________
c = ___________
Answer:
[tex] \boxed{ \boxed{ \mathfrak{a = - \frac{1}{2 } \: b = 2 \: c = 4}}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:quadratic equationPEMDAStips and formulas:the parabola crosses f(x) at (4,0)the vertex of the parabola (2,6)vertex:(h,k)h=-b/2ak=f(x)vertex form:f(x)=a(x-h)²+kstandard form:ax²+bx+clet's solve:the vertex form of the equation is
[tex] \sf f(x) = a(x - 2 {)}^{2} + 6[/tex]let's figure out a
since the parabola crosses f(x) at (0,4)
therefore
[tex] \sf a(0 - {2)}^{2} + 6 = 4[/tex][tex] \sf simplify \: parentheses : \\ \sf a( - 2 {)}^{2} + 6 = 0[/tex][tex] \sf simplify \: squres : \\ \sf \: 4a + 6 = 4[/tex][tex] \sf cancel \: 6 \: from \: both \: sides : \\ \sf 4a + 6 - 6 = 4 - 6 \\ \sf 4a = - 2 [/tex][tex] \sf divide \: both \: sides \: by \: 4 : \\ \sf \frac{4a}{4} = - \frac{ 2}{4} \\ \sf a = - \frac{1}{2} [/tex]let's figure out b,c
we have to substitute the value of a into the vertex form and then simply it to get b and c[tex] \sf substitue \: the \: value \: of \: a \: into \: the \: vertex \: form \: of \: the \: equation : \\ \sf \frac{1}{2} (x - 2 {)}^{2} + 6[/tex][tex] \sf use \: (a - b {)}^{2} = {a}^{2} - 2ab + {b}^{2} \: to \: simplify \: the \: exponet : \\ \sf - \frac{1}{2} ( {x}^{2} - 2.x.2 + {2}^{2} ) + 6 \\ \sf - \frac{1}{2} ( {x}^{2} - 4x + 4) + 6[/tex][tex] \sf distribut e \: - \frac{1}{2} \: between \: the \: parentheses : \\ \sf - \frac{1}{2} x + 2x - 2 + 6[/tex][tex] \sf add : \\ \sf - \frac{1}{2} x + 2x + 4[/tex]therefore
[tex] \sf \: b = 2[/tex][tex] \sf \: c = 4[/texAs part of your exercise routine, you jog around the neighborhood block which is shaped like a right triangle. Your street, the hypotenuse of the triangle, is 850 feet long. If the total distance around your block is 2000 feet, what are the distances of the other two streets that enclose your block?
Answer:
The other distances are 400 ft and 750 ft.
Step-by-step explanation:
a + b + c = 2000
a + b + 850 = 2000
a + b = 1150 Equation 1
a^2 + b^2 = c^2
a^2 + b^2 = 850^2
a^2 + b^2 = 722,500 Equation 2
a + b = 1150
a^2 + b^2 = 722,500
a = 1150 - b
(1150 - b)^2 + b^2 = 722,500
1,322,500 - 2300b + b^2 + b^2 = 722,500
2b^2 - 2300b + 600,000 = 0
b^2 - 1150b + 300,000 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-1150) \pm \sqrt{(-1150)^2 - 4(1)(300,000)}}{2(1)} [/tex]
[tex] x = \dfrac{1150 \pm \sqrt{1,322,500 - 1,200,000}}{2} [/tex]
[tex] x = \dfrac{1150 \pm \sqrt{122,500}}{2} [/tex]
[tex]x = \dfrac{1150 \pm 350}{2}[/tex]
[tex] x = \dfrac{1500}{2}~~~or~~~x = \dfrac{800}{2} [/tex]
x = 750 or x = 400
Answer: The other distances are 400 ft and 750 ft.

Answer:
137. 5
Step-by-step explanation:
Firstly you have to turn the mixed fraction into an improper fraction.
x/2/5 = 55/4
Now you multiply both sides by the denominators.
(5)(4) x/2/5 = 55/4 (5)(4)
2x = 275
137. 5
