Answer:
A = 78.5 cm²
Step-by-step explanation:
Area of Circle = πr²
A = (3.14)(5)²
A = (3.14)(25)
A = 78.5 cm²
The area formula of a circle is r² x π.
With that being said, we can now substitute in our radius value.
(5)² x π
From there, we can find the square root of the radius.
(25) x π
And then we can multiply by pi to solve.
78.539816..
Finally, we'll round to the nearest tenth to get our answer.
78.5
Therefore, the area of the circle is 78.5 cm.

Ben is buying a book that costs $14.75 and a magazine that costs $5.25. If he has a store cupón for 15% off and sale tax is 8%, how much will he pay in total?
Answer:
$18.36
Step-by-step explanation:
14.75+5.25=20
20 x 0.15 = 3
20 - 3 = 17
17 x 0.08=1.36
17+ 1.36 =18.36
total is $18.36

n/4=-19 what does n equal to?
Answer:
n/4 = -19
=> n = (-19) x 4
=> n = -76
Hope this helps!
:)
Answer:
-76
Step-by-step explanation:
You have to moltiply lefy side and right side by 4, so you have:
4 × n/4 = 4 × (-19)
the left 4 goes out because 4/4 = 1
n = 4 × (-19)
n = -76

Step-by-step explanation:
8^4 = 4096
6^3 = 216
16^-2 = 0.00390625
4096x216x0.00390625 = 3456

Answer:
(3/2)^3
Step-by-step explanation:
The trick here is to identify the common base (it is 2) and express all factors except for 3^2 as powers of 2 that can be added or subtracted.
Note that 8 = 2^3, 6 = 2 * 3, 16 = 2^4 and 32 = 2^5. Using this info, we can immediately begin reducing the given expression:
(2^3)(2^3)(3^3) 2^6*3^3 3^3
(8^4)(6^3)(16^-2)÷32 => ----------------------- = ---------------- = --------------
2^4*2^5 2^9 2^3
= (3/2)^3

What is Anti-lock Brakes?An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle.

Write an equation of the line in slope intercept form.
Answer:
y=[tex]\frac{-1}{2}[/tex]x+1
Step-by-step explanation:
First, let's do the easiest part, finding the y-intercept, which shows up at the end of your slope intercept equation, y=mx+b, where slope is rise over run!
- Simply look for where the coordinate is on the y-intercept, which is at y = 1!
Then, we need to find our rise over run, which is basically counting from point a to point b. To get to the lower coordinate from the top, we go down two (-2), and over 4. Which means we "rose" -2, and "ran" 4! It's -2 because we went DOWN, and positive 4 because we went FORWARD. This gave us 2 over 4, which is the same as 1 over 2!

3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6
Answer:
5 3/8
Step-by-step explanation:
3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6
Get a common denominator for the right side
3 1/8 ÷(x−4 7/28 )= 17/18 +1 15/18
Combine like terms
3 1/8 ÷(x−4 7/28 )= 1 32/18
3 1/8 ÷(x−4 7/28 )= 2 14/18
3 1/8 ÷(x−4 7/28 )= 2 7/9
We have a ÷ b = c
Rewriting as a ÷c = b
3 1/8 ÷ 2 7/9 = (x−4 7/28 )
Changing from mixed numbers to improper fractions
25/8 ÷ 25 /9 = (x−4 7/28 )
Copy dot flip
25/8 * 9/25 = (x−4 7/28 )
9/8 = (x−4 7/28 )
Add 4 7/28 to each side
9/8 + 4 7/28 = (x−4 7/28 )+ 4 7/28
Simplifying the fractions
9/8 + 4 1/4 = x
Getting a common denominator
9/8 + 4 2/8 =x
4 11/8 =x

This is the formula of how to answer this question hopefully it helps :)
Sugar = Flour
A cup of sugar weighs about 7 ounces, and a cup of all-purpose flour weighs about 4-1/2 ounces. So, if we're building a recipe with 1 cup sugar, we'll need about 1-1/2 cups flour (about 6-3/4 ounces).

write the equation of a line perpendicular to y=3x-2 through the point (-5,8).
Answer:
y=-1/3x +29/3
Step-by-step explanation
We know that the line perpendicular to a slope of 3 is it's opposite reciprocal. So the slope is -1/3. Substitute -5 as X and 8 as Y so you get:
8= -5/3x +b.
B= 29/3
That's your answer.
solve the diagram below to write an equation and solve for x.
Answer: The equation is (3x) + (2x + 20) + (x+10) = 180, and the x = 25.
Step-by-step explanation:
First, you know that all the measures of angles equal 180°.
So, we can make this equation:
(3x) + (2x + 20) + (x+ 10) = 180
Then, solve for x:
3x + 2x + 20 + x + 10 = 180
Combine the like terms that have the variable, x, in them:
6x + 20 + 10 = 180
Now combine the constant numbers:
6x + 30 = 180
Next, subtract 30 from that side:
6x = 180 - 30
6x = 150
Then, divide:
[tex]\frac{6x}{6}[/tex]= [tex]\frac{150}{6}[/tex]
x = 25
Therefore, the equation is (3x) + (2x + 20) + (x +10) = 180, and the x is 25.
Hope this helps! :)
Answer:
x = 25°
Step-by-step explanation:
Hello!
The sum of angles in a triangle is equal to 180°. If we add all the measures and set it to 180°, we can solve for x.
Solve for x3x + 2x + 20 + x + 10 = 1806x + 30 = 1806x = 150x = 25The value of x is 25°.

Answer:
∠ GHI = 40°
Step-by-step explanation:
The inscribed angle GHI is half the measure of the intercepted arc GI, thus
∠ GHI = 0.5 × 80° = 40°
The measure of the ∠GHI is 40°.
What is an Inscribed Angle?An inscribed angle is the angle that an arc at any point on the circle subtends.
From the Inscribed angle theorem:
A circle's inscribed angle is half of the central angle that subtends the same arc on the circle, according to the inscribed angle theorem.
That means,
The measure of the ∠GHI
= the measure of the arc GI /2
= 80°/2
The measure of the ∠GHI = 40°
Therefore, the measure of center angle is 40°.

1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answer:
• In a right triangle, the two sides adjacent to the
right angle are known as the _________, or
______ and ______.
• The side opposite from the right angle
is called the ___________________, or ______.
• The hypotenuse is always the _______________ side of a right triangle.
Step-by-step explanation:
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ
