Answer:
[tex] {x}^{2} + ( \frac{ \sqrt{3} }{2} ) {}^{2} = 1 \\ {x}^{2} = \frac{1}{4} \\ x = \frac{1}{2} \: \: or( \frac{1}{2} ) \\ x > 0 \\ therefore \: \: x = \frac{1}{2} [/tex]
Answer:
[tex]x=-\frac{1}{2}[/tex]
Step-by-step explanation:
equation of a circle: [tex](x - h)^2+(y-k)^2=r^2[/tex]
where (h, k) = center and r = radius
From inspection, we can see that the center of the circle = (0, 0)
and the radius = 1
[tex]\implies (x - 0)^2+(y-0)^2=1^2[/tex]
[tex]\implies x^2+y^2=1[/tex]
Substitute [tex]y=\frac{\sqrt{3}}{2}[/tex] into [tex]x^2+y^2=1[/tex] and solve for [tex]x[/tex]:
[tex]\implies x^2+(\frac{\sqrt{3}}{2})^2=1[/tex]
[tex]\implies x^2+\frac{3}{4}=1[/tex]
[tex]\implies x^2=\frac{1}{4}[/tex]
[tex]\implies x=\pm \sqrt{\frac{1}{4}}[/tex]
[tex]\implies x=\pm\frac{1}{2}[/tex]
As point P is in quadrant 2, [tex]x[/tex] is negative, so [tex]x=-\frac{1}{2}[/tex]

At Best Buy they have a 60" TV that sells for $1250 and is on sale for 15% off. If the sales tax is 6.5%, what is the final cost?
Answer:
Step-by-step explanation:
The sale price = Initial Cost - 15% of the initial Cost
The sale price = 1250 - 15/100 * 1250
The sale price = 1250 - 187.5
The Sale Price = 1062.5
Now you add on the sales tax
Cost with Sales Tax = 1062.50 + 6.5/100 * 1063
Cost with Sales Tax = 1062.50 + 69.06
Cost with Sales Tax = 1131.56 dollars.
Gerald fi nds that it takes 30 ml of a
standard solution to neutralize 12 ml of
a solution of unknown concentration.
If he starts with 20 ml of the unknown
solution, it takes 50 ml of standard
solution to neutralize it. Assuming a linear
relationship exists between the amount
of unknown solution and the amount of
standard solution required to neutralize
it, how much unknown solution can
be neutralized with 175 ml of standard solution?
You have $575 to spend on clothes for the school year. You want to by 8 pairs of pants that cost $352.45 including tax and hoodies that will have a 8.7 % sales tax. What is the inequality that represents the amount of money you have to spend?
Answer:
352.45 + 1.087x ≤ 575
Step-by-step explanation:
The most you can spend is $575, so the total you spend must be ≤ 575.
You already have a total for the pants of $352.45.
352.45 + price of hoodies ≤ 575
Let x = total price of the hoodies before tax.
The price of the hoodies with tax is
x + 8.7% of x = x + 0.087x = 1.087x
The inequality is
352.45 + 1.087x ≤ 575
There are 6 classes going on a field trip. Each class has 26 students.
Each car can hold 5 students. How many cars are needed to get all
he students to the field trip?
Answer:
32 cars
Step-by-step explanation:
If each class has 26 students, we can multiply the number of classes, 6, by the amount of students in each class, to find the total amount of students going on the field trip.
6 * 26 = 156 students
Each vehicle can hold 5 students. To find the amount of vehicles needed to transport all the children, we need to divide the number of students by 5.
156 / 5 = 31.2 vehicles
I don't think they plan on driving 0.2 of a vehicle, so we would have to round. We can't round down because if we did, there would be one student left.
31 * 5 = 155 students
Unless the student plans on biking there, they would have to have 32 cars ready to drive the students to the field trip.

find the value of x and give reasoning in the following image
Answer: 80
Step-by-step explanation:
Angle FGB = 80 degrees b/c supplementary angles.
By the sum of interior angles of a quadrilateral, angle FEB = 360 - 75 - 95 - 90 = 100 degrees.
x is supplementary with this angle and is this 180 - 100 = 80.
A circle is shown 10 cm. What is the circumference of the circle, to the nearest tenth of a centimeter
Answer:
31.42cm
Step-by-step explanation:
Answer. We know that C = πd. Since the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).
How to solve questions
A bag contains 4 black balls and 6 white balls. Sarah picks a ball at random from the bag and replaces it back in the bag. She then picks another ball at random from the bag.
You may draw a tree diagram on paper to answer the following questions.
Calculate the probability that she picks
a) 2 white balls or 2 black balls
Answer:
13/25
Step-by-step explanation:
number of black balls = 4
number of white balls = 6
⇒ total number of balls = 10
As the balls are always replaced after being picked:
probability of picking a black ball = P(B) = 4/10probability of picking a white ball = P(W) = 6/10Therefore,
P(W) and P(W) = 4/10 x 4/10 = 16/100 = 4/25
P(B) and P(B) = 6/10 x 6/10 = 36/100 = 9/25
P(W and W) or P(B and B) = 4/25 + 9/25 = 13/25

Solve the following inequality.
-10 < 5 + X <-5
[?] < < <[ ]
Enter
Solution:
Simplify the inequality one by one:
-10 ≤ 5 + x < -5=> -10 - 5 ≤ x => -15 ≤ x => 5 + x < -5=> x < -5 - 5=> x < -10This means that...
-15 ≤ x < -10Hoped this helped!
Required solution :
First solving for -10 < 5 + x
⇒-10 - 5 < x
⇒ -15 < x
Now for 5 + x < -5
⇒ x < -5 - 5
⇒ x < -10
Therefore,
-15 < x < -10When an object falls due to gravity on Earth, the acceleration is 9.8 m/s. A student drops a rock
down a mineshaft. It takes 3.00 seconds for the rock to hit the bottom of the shaft. What is the
velocity of the rock as it impacts?
Answer:
29.4 m/s
Step-by-step explanation:
Use v = at with a = 9.8 m/s^2 and t = 3.00 sec
v = 9.8 * 3.00 = 29.4 m/s
10. Jan purchased 140 shares of stock in the ABC Company at a price of $18.75 per share. During the
next three days, the value declined by $1.00, $1.75 and $1.50. What was the value of a share of ABC
stock at the end of three days?
[tex]\bold{\huge{\orange{\underline{ Solution }}}}[/tex]
[tex]\bold{\underline{ Given :- }}[/tex]
Jan purchased 140 shares of stock in ABC company at a price of $18.75 per share During the next 3 days, the value of share declined by $1.00 , $1.75 and $1.50[tex]\bold{\underline{ To \: Find :- }}[/tex]
We have to find the value of a share of ABC stock at the end of 3 days[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]
According to the question,
Cost of 1 share of ABC company = $18.75
Therefore,
Cost of 140 shares purchased by Jan in the ABC company
[tex]\sf{ = 140 × 18.75 }[/tex]
[tex]\sf{ = 2625\: dollars }[/tex]
Now,
For next 3 days, the value of share declined
[tex]\sf{ = (1 + 1.75 + 1.50)dollars }[/tex]
[tex]\sf{ = 4.25 \: dollars }[/tex]
Therefore,
The value of shares after 3 days will be
[tex]\bold{ = }{\bold{\frac{2625 - 4.25}{ 140}}}[/tex]
[tex]\bold{ = }{\bold{\frac{ 2620.75}{ 140}}}[/tex]
[tex]\bold{\red{ = 18.75\: dollars}}[/tex]
Hence, The value of share after 3 days will be $18.75 .

The total cost of an eraser, 2 similar pens and a ruler is $13. The total cost of 2 similar erasers, a pen and a ruler is $11. The cost of 3 erasers is the same as that of 2 rulers. Find the cost of a ruler.
Answer:
$3
Step-by-step explanation:
Let the cost of an eraser, a pen and a ruler be $e, $p, and $r respectively.
Given:
e +2p +r= 13 -----(1)
2e +p +r= 11 -----(2)
3e= 2r -----(3)
(1) ×3:
3e +6p +3r= 39 ----(4)
Substitute (3) into (4):
2r +6p +3r= 39
6p +5r= 39 -----(5)
(2) ×3:
6e +3p +3r= 33 -----(6)
Substitute (3) into (6):
2(2r) +3p +3r= 33
4r +3p +3r= 33
3p +7r= 33 -----(7)
Let's rewrite equations (5) &(7) so it's easier to compare them:
6p +5r= 39 -----(5)
3p +7r= 33 -----(7)
We can eliminate the term p to find the value of r. This can be done by making sure that the coefficient of p is equal in both equations.
(7) ×2:
6p +14r= 66 -----(8)
(8) -(6):
6p +14r -(6p +5r)= 66 -39
Expand:
6p +14r -6p -5r= 27
9r= 27
r= 27 ÷9
r= 3
Thus, the cost of a ruler is $3.

what are the measures of the angles of a triangle (4x-4) 58 (8x-18)
calculate the interest if R300 is invested for 3years at 5% per annum compound interest.
Answer:
SIMPLE INTEREST=PRT/100
P=300
R=5%
T=3
SI=300×5×3/100
SI=3×5×3
SI=45
Answer:
Compound InterestPrincipal(P) = R300 rate( r )=5% n=5 years
Total amount
= P(1+r/100)^n
= 300(1+5/100)^3
=R347. 2875
Interest
= Total amount - Principal amount
= 347.2875 - 300
= R47.2875
= R47.30( rounded up to 2
decimal places)

If an exterior angle measure of a regular
polygon is 20°, how many sides does the
polygon have? What is the measure of each interior angle?
Answer:
n=18 sides
Step-by-step explanation:
Given: Exterior angle =20°
Find: sides of a regular polygon
Solution: θ=(360°)/side , θ=20°
Let n= number of sides
θ=360°/n
20=360/n
n=360/20
n=18
