Answer:
8.40
Step-by-step explanation: This means the cost of the item to you is $8.4. You will pay $8.4 for a item with original price of $12 when discounted 30%. In this example, if you buy an item at $12 with 30% discount, you will pay 12 - 3.6 = 8.4 dollars.
Answer:
The new total will be $8.40.
Step-by-step explanation:
The 30% off discount gives you $3.60 off of your purchase.
A circular plate has circumference 33.3 inches. What is the area of this plate? Use 3.14 for Pi.
The area of this plate is_____about square inches.
(Round the final answer to the nearest whole number as needed. Round all intermediate values to the nearest
thousandth as needed.)
Answer:
88 square inches
Step-by-step explanation:
A circular plate has circumference 33.3 inches.
Step 1
We find the radius
The formula to find the radius go a circle given circumference is
= C /2π
r = 33.3/2 × 3.14
r = 5.3025477707 inches
Approximately to the nearest thousandth = 5.303 inches
Step 2
What is the area of this plate? Use 3.14 for Pi.
The area of a circle = πr²
Where
π = 3.14
r = 5.3025477707 inches
Hence
Area of the circle = 3.14 × (5.303inches)²
= 88.30248026 square inches
Approximately to the nearest whole number the area of the circle = 88 square inches
The area of this plate is about 88 square inches.

Write a system of equations to represent the number of each type of basket Jake scored.
The system of equations that represents the number of each type of basket Jake scored is given by:
x + y = 13
2x + 3y = 28
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Number of two-point shots.Variable y: Number of three-point shots.Jake scored 28 points in his basketball game by shooting only two-point and three-point shots, hence:

Find the tangent line equation of the curve at the given point. Y=arcsin(7x) at the point where x=sqrt2/14
Answer:
[tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]
Step-by-step explanation:
The equation of the curve is
[tex]Y = sin^{-1}(7x)[/tex]
To find the equation of tangent we need to differentiate this equation w.r.t x
So, differentiating we get
[tex]Y'=\frac{7}{\sqrt{1-49x^2} }[/tex]
This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is [tex]x = \sqrt{\frac{1}{7} }[/tex]
Then slope would accordingly be
[tex]Y'=\frac{7}{\sqrt{1-49/49} }[/tex]
= ∞
For, [tex]x = \sqrt{\frac{1}{7} }[/tex], [tex]Y = sin^{-1}(7/7)= \pi/2[/tex]
Equation of tangent line, in the point slope form, would be [tex]Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})[/tex]

What is Probability ?Probability is the ratio of occurring a certain event out of the total possible events.
If the given statement contains OR we use addition and if the given statement contains AND we use multiplication.
From the given data
Total no. of regions in the circle is 5
The probability that the arrow will land on 1 or 2 is
P(1) = 1/5
P(2) = 1/5

Step-by-step explanation:
hello!
3) in the question, it says the cross section is a square, and the area of PQRS is 81.
for the square, we know that the length and height have to be the same, so if the area is 81, then we know the sides are both 9 because 9*9 is 81 and they're the same numbers multiplied. (same height and length)
with the information that all 4 sides of the square is 9 and the other side is labeled 10, we can figure out the rest.
both squares : 81+81=162
both 10 by 9 sides: 90+90=180
both 10 by 9 sides (top and bottom): 90+90=180
total surface area=162+180+180=522
4) for this problem, we can see that the triangle is a right triangle.
to solve the area of the triangle, we can do (9*12)/2=108/2=54.
there are two sides with triangles, so we double 54 (54*2=108)
9 by 10 side: 90
10 by 12 side: 120
now for the last slide, theres no information on the length. the formula for the diagonal is
a^2+b^2=c^2
which is
9^2+12^2=81+144=255=15^2
with this, the area of the rectangular side gives us 10*15 which is 150.
adding it together, we get
108+90+120+150=468.
hope this helps!
A rectangular logo is made up of 3 squares and 8 small squares the length of the rectangle is 36 cm
Find the area of the logo
Answer:
The total area is 594cm.²
Step-by-step explanation:
The top and bottom each have a length of 36 cm.
Blue side:
36/3= 12cm. (36/3 for the length of one side of a blue square)
12*12= 144cm.² (area of one blue square)
144*3= 432cm.² (area of all the blue squares)
Orange side:
36/8= 4.5cm. (the length of one side of an orange square)
4.5*4.5= 20.25cm.² (the area of one orange square)
20.25*8= 162cm.² (the area of all the orange squares)
Total area:
432+162= 594 cm.²

A coke can and a monster can are each in the shape of a right circular cylinder. The cans have the same radius but the height of the monster can is 2 times the height of the coke can. What is the ratio of the volume of the coke can to the volume of the monster can
Answer:
1 : 8
Step-by-step explanation:
Given the height of 2 similar cylinders = a : b , then
ratio of volumes = a³ : b³
Here the ratio of heights = 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8

Find the values of x and y. Write your answers in simplest form.
Answer:
To find X you'll need this formula Tan 30, and this one to find y cos 30.
Step-by-step explanation:
tan 30 = 9 / x.
tan 30*x = 9
x = 9 / tan 30
x = 15.58
To find y, the value of X will be needed, which is 15.5 that we just found.
Cos= A/H
Cos 30 = 15.58/ y
Cos 30 * y = 15.58
y = 15.58/ cos 20
y = 17.99

SHOW YOUR WORK. The volume of the cylinder is 235.6 ft cubed. Find the height.
Answer:
Answer: 3 feet
Step-by-step explanation:
Here's the complete question:
The volume of the cylinder is 235.6 cubic feet the radius is 5ft. Find the height.
Note that Volume of a cylinder = πr²h
where Volume = 235.6 feet³
Radius = 5 feet
Height = Unknown
Then, we put the values back into the question and this will be:
V = πr²h
235.6 = 3.14 × 5² × h
235.6 = 3.14 × 25 × h
235.6 = 78.5 × h
h = 235.6 / 78.5
h = 3 feet
The height is 3 feet

Answer:
78 cm^2
Step-by-step explanation:
This will require 3 steps.
1) Area of the entire rectangle
18cm * 8 cm = 144 cm^2
2) Area of the square with one side length of 9cm
The missing measurement for the heights below 2cm
8cm - 2 cm = 6 cm
This area will be 6cm * 9 cm = 54 cm^2
3) Triangle
You have your height, which is 6cm
You also have your base, 18 cm total length minus the 5 cm stated minus the 9 cm also stated.
18cm - 5cm - 9 cm = 4 cm
The area of a triangle is A= h b/2
A = 6 * (4/2)
A = 12 cm^2
Now substract the sum of the smaller rectangle and the triangle from your large triangle
144 - 54 - 12
Which statement must be true?
