Jackie has 1/3 of a Hershey bar.steven has 4/12 of a Hershey bar.How much do they have together?
Answer: 2/3
Step-by-step explanation: To find how much of the candy bar they each have, we will have to add the fractions. To add unlike fractions such as 1/3 and 4/12, we first need to find a common denominator. The common denominator of 3 and 12 is simply the least common multiple of 3 and 12 which is 12. To get 12 in the denominator of 1/3, we multiply the numerator and denominator by 4 to get 4/12. Notice that our second fraction already has 12 in the denominator so we can now add these fractions.
[tex]\frac{4}{12}[/tex] + [tex]\frac{4}{12}[/tex] = [tex]\frac{8}{12}[/tex].
Notice that 8/12 can be reduced by dividing both the numerator and denominator by 4.
8 ÷ 4 = 2
12 ÷ 4 = 3
Therefore, Jackie and Steven have 2/3 of a Hershey bar.

James purchases a property for $150,000 in 2015. In the first year of ownership the capital appreciation of the property (how much its value increases by per annum) is 4%. In year 2, the housing market suffers a crash and the house experiences a capital depreciation of 6%. Calculate the value of the property, to the nearest $1,000, at the end of year 2. Round your answer to the nearest $1,000.
Answer:
$147,000
Step-by-step explanation:
After 1st year:
we need to increase 150,000 by 4%. That means the value would be 150,000 multiplied by 1.04. So:
150,000 * 1.04 = 156,000
After 2nd year:
The new appreciated value of 156,000 will now suffer a loss of 6%. So we need to find the new value by multiplying 156,000 by 0.94 (6% loss). So:
156,000 * 0.94 = 146,640
To the nearest 1000, this would be $147,000
what is the value of x?
enter your answer in the box
Answer:
x = +/-10°
Step-by-step explanation:
[2(x+10)]°=
[2x + 20] =
[2x] = [-20]
2x/2 = -20/2
x = -10
(3x - 30)°
3x/3 = 30/3
x = 10
Answer:
The value of x = 50°
Step-by-step explanation:
As,
[2(x+10)]° & (3x-30)° both are Vertically opposite angles.
we know,
vertically opposite angles are equal .
so,
2(x+10) = 3x-30
⇒2x+20 = 3x-30
⇒3x-2x=20+30
∴x=50
∴The value of x = 50°

A block of oak has volume of 200 cubic centimeter and weighs 0.12 kilograms. What is its density? Will it floats on water?
Answer:
Density = Mass (grams) / Volume (Milliliters)
Density = 120 grams / 200 ml
Density = .60 grams per ml
Density is less than 1 so it will float on water.
Step-by-step explanation:
Step-by-step explanation:
It is given that,
Volume of the block of oak, V = 200 cc
Mass of the block of oak, m = 0.12 kg = 120 grams
The density of any substance is given by mass per unit volume. mathematically, it is given by :
[tex]d=\dfrac{m}{V}[/tex]

Finally, we'll drag the corresponding domain description into the box under each graph based on our analysis.
For the first graph, drag "all real numbers".For the second graph, drag "all real numbers except [tex]\( x = -3 \)[/tex] and [tex]\( x = 3 \)[/tex]".For the third graph, drag "all real numbers between -3 and 3".To answer the question presented in the image, we need to match each graph with its corresponding domain. Here's how to determine the domain for each graph step by step:
1. Examine the first graph:
Look at where the graph exists along the x-axis. If the graph covers the entire x-axis without any breaks, then the domain is all real numbers. If there are breaks or gaps, note the intervals where the graph does not exist.2. Examine the second graph:
Repeat the process, looking for gaps along the x-axis.Check if the graph is only above or below the x-axis to see if it's only positive or negative real numbers. Look for vertical lines that the graph might approach but not touch (asymptotes), which would indicate values that are not included in the domain.3. Examine the third graph:
Again, look for any breaks along the x-axis. Determine if the graph is bounded within a certain range on the x-axis.Now, let's apply this process to each graph in the uploaded image:
First Graph: The graph covers all x-values without any breaks, so its domain is "all real numbers".Second Graph: The graph has a break at [tex]\( x = -3 \)[/tex] and [tex]\( x = 3 \)[/tex], so the domain is "all real numbers except [tex]\( x = -3 \)[/tex] and [tex]\( x = 3 \)[/tex]".Third Graph: The graph exists only between [tex]\( x = -3 \)[/tex] and [tex]\( x = 3 \)[/tex], so the domain is "all real numbers between -3 and 3".Which number is less than -3 or greater than 5?
Answer:
4
Step-by-step explanation:
To find numbers less than -3 or greater than 5, we consider numbers to the left of -3 and to the right of 5 on the number line.
Explanation:To find the numbers that are less than -3 or greater than 5, we can consider numbers that are to the left of -3 on the number line or to the right of 5. Any number less than -3 will be represented by a point to the left of -3, and any number greater than 5 will be represented by a point to the right of 5. This means that any number less than -3 or greater than 5 will include all the numbers from negative infinity to -3, and all the numbers from 5 to positive infinity.

C. a reflection in the x-axis, followed by a counterclockwise rotation of 180 about the origin
D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin
Answer:
D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin
Step-by-step explanation:
Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a 90°-clockwise rotation option, we have to go with something similar to that, which would be a 270°-counterclockwise rotation. If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].

A detailed explanation of whether [tex]\sqrt{72}[/tex] is rational or irrational, with examples and definitions to support the answer.
To determine whether [tex]\sqrt{72}[/tex] is rational or irrational, let's first simplify the expression:
[tex]\sqrt{72}[/tex] = [tex]\sqrt{36*2}[/tex]
[tex]\sqrt{72} = \sqrt{36}[/tex] × [tex]\sqrt{2}[/tex]
[tex]\sqrt{72[/tex] = [tex]6\sqrt{2}[/tex]
Now, 2 is an irrational number, as it cannot be expressed as a fraction of two integers where the denominator is not zero. Since [tex]\sqrt{2}[/tex] is irrational and [tex]\sqrt{6}[/tex] is rational, the product [tex]6\sqrt{2}[/tex] is also irrational.
Therefore, [tex]\sqrt{72}[/tex] is irrational.

The square of the product of 4 and a number is the sum of the number and 15
Answer:
The number is 1 or -0.94 ( to the nearest hundredth).
Step-by-step explanation:
Let the number be x, then:
(4x)^2 = x + 15
16x^2 - x - 15 = 0
x = [-(-1) +/- sqrt(1 - 4 * 16 * -15)] / 32
x = 32/32 = 1 or
x = -0.94.
Answer:
x=1 or x = - [tex]\frac{15}{16}[/tex]
Step-by-step explanation:
To solve this problem, we will follow the steps below;
First, we need to re-write the question in a mathematical format.
Let x be the number
"The square of the product of 4 and a number is the sum of the number and 15" can be written mathematically as;
(4x)² = x + 15
16x² = x + 15
This equation can be re-written as;
16x² - x - 15 = 0
This is a quadratic equation, we can solve by formula method
x = -b ±√b² - 4ac /2a
From the equation above, a = 16 b = -1 and c= -15
We can now proceed to insert the values into the equation
x = -b ±√b² - 4ac /2a
x = -(-1) ±√(-1)² - 4(16)(-15) /2(16)
x = 1 ±√1 + 960 /32
x = 1 ±√961 /32
x = 1 ± 31 /32
Either x = [tex]\frac{1+ 31}{32}[/tex] or x = [tex]\frac{1-31}{32}[/tex]
x = [tex]\frac{32}{32}[/tex] or x =[tex]\frac{-30}{32}[/tex]

for how many miles of driving was Juliet charged?
(Assume there is no tax.)
A) 15
B) 120
C) 533
D) 633
Answer:
B) 120
Step-by-step explanation:
m = miles
$98=$80+$0.15m
$98-$80=$80-$80+$0.15m
$18=$0.15m
$18/$0.15=$0.15m/$0.15
120=m
Juliet drove 120 miles for $98.
(this is a good explanation, I guess)
Answer:
Option B) 120 miles
Step-by-step explanation:
Company charges per day for a car rent = $80
and per mile driven = $0.15
Juliet rented a car for one day and she was charged a total = $98
Let Juliet traveled x miles
$80 + $0.15x = $98
0.15x = 98 - 80
0.15x = 18
x = [tex]\frac{18}{0.15}[/tex]
x = 120 miles

joe has $4 more than Hector. Hector has $8 more than Tami. If Tami has $x, write an expression for the amount of money Joe has.
Answer: The answer to your question should be ($x +$8) + $4
Step-by-step explanation:
First of all ignore the dollar sign. It’s irrelevant to the problem and we aren’t dealing with decimals. First of all, we know that Hector has $8 more than Tami and Joe has $4 more than Hector so first we need to find how much money Hector has. Since Hector has $8 more than Tami and we know that Tami has $x we $x+$8 is Hectors amount of money. Since Joe has $4 more than Hector and we know Hectors money is $x + $8 Joe’s money is ($x+$8) + $4.
