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
suppose a 3-digit number is to be formed using the digits 1,2,3,4,5. How many different numbers can be formed. (digits can be repeated)
Answer:
125
Step-by-step explanation:
For the first digit of our number, we have 5 options (1, 2, 3, 4, 5). For the second and third digits, we still have 5 options because the digits can be repeated. This means that the total different numbers we can make is 5 * 5 * 5 = 125 numbers. Hope this helps!

write an equation and solve round to the nearest hundredth where necessary. 21 is 35% of what number
Answer:
21 is 35% of 60.
35% * x = 21
Multiply both side by 100 and divide both sides by 35.
x = 21 * 100/35
21 * 100 = 2100
2100/35 = 60.

Answer:
108
Step-by-step explanation:
8^4 = 4096
6^3 = 216
16^-2 = 0.00390625
4096x216x0.00390625 = 3456
3456/32 = 108
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

The measure of GI is 80 degrees. What is the measure of
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°.

What is the equation of the line in the slope intercept form
Answer:
Equation of line; y = - 6x
Step-by-step explanation:
As we can see from this graph, point ( 0, 0 ) lying on this graph intersects the y - axis such that it forms a y - intercept of 0;
At the same time we can note that the change in y / change in x, in other words the slope, differs by a rise of 6 / run of - 1, 6 / - 1 being a slope of - 6;
If this equation is in slope - intercept form ⇒
y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,
Equation of line; y = - 6x
Answer:
y = -6x
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
the y intercept is 0 since it crosses the y axis at 0
To find the slope we need to points (0,0) and (10,-60)
m = (y2-y1)/(x2-x1)
= (-60-0)/(10-0)
= -60/10
= -6
The equation for the line is
y = -6x +0
y = -6x

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!

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

Answer:c,d
Step-by-step explanation:
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°.

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.
