Answer:
450$
Step-by-step explanation:
So lets add otgether everything that she NEEDS to buy, to see how much of 1500$ she can use on what she WANTS to buy.
So:
500+50+100+100+300
=
1050
This is the total cost of what she NEEDS to buy
Now lets subtract this from her income:
1500-1050
=
450
So we now know that the amount of money she has left to spend on what she WANTS is 450$
Hope this helps! :)
20 - 4b/8= 18
another one :)
multiply by 8 on both sides
(20)8 - 8(4b/8) = (18)8
160 - 4b = 144
subtract 160 on both sides
160 - 160 - 4b = 144 - 160
-4b = -16
divide by -4 on both sides
-4b/-4 = -16/-4
b = 4
Mr. Brady draws a fraction on the board. Ken says it's 2/3, and Dan said it's 3/2. Do both of these fractions mean the same thing? If not, which fraction is greater?
Answer:
Both of these fractions do not mean the same thing. The greater fraction is 3/2.
Step-by-step explanation:
Answer:
3/2 is greater than 2/3
Step-by-step explanation:
2/3 means 2 divided by 3. Since 2 is smaller than 3, 2 divided by 3 is less than 1.
3/2 means 3 divided by 2. Since 3 is greater than 2, 3 divided by 2 is greater than 1.
3/2 is greater than 2/3

Consider this equation: 0B = 21. Is the equation always false, no matter what value you give the variable? Justify your answer.
Answer:
because the variable is being multiplied by 0.
Step-by-step explanation:
the B in the equation is just a place holder for any number you can think of.
the problem with that is that any number times 0 will always give you 0, so the equation will look like this now
0 = 21
this equation is false because 0 is not equal to 21.
21 is equal to 21.

Hi, extra points! The answer is 32(sign)3ft^2 just need the work with it
Answer:
A hexagon has 6 internal angles, and the sum of the interior angles is 720°
If the hexagon is regular, so all the internal angles are equal, the measure of each internal angle is:
720°/6 = 120°
Ok, now let's look at the image.
We can "craft" a triangle rectangle. such that one cathetus is the line of 4ft that we can see in the image.
The hypotenuse is the line that connects the center, with the bottom right vertex.
Half of the bottom side is the other cathetus.
Because the hypotenuse divides the vertex in exactly two halves, the bottom right angle of the triangle rectangle will be 120°/2 = 60°.
So of this triangle rectangle, we know:
one angle equal to 60°
The opposite cathetus of this angle, which measures 4 ft.
Let's find the other cathetus of the rectangle:
We can use the identity:
Tan(a) = (opposite cathetus)/(adjacent cathetus)
In this case, we have:
Tan(60°) = 4ft/x
The value of x is:
x = 4ft/Tan(60°) = 4ft/√3
Because Tan(60°) = √3
And we know that the area of a triangle rectangle is the product of the length of each cathetus divided by two.
Then the area of our triangle rectangle is:
A = (4ft*4ft/√3)/2 = (8/√3) ft^2
And there are 12 of these right triangles inside the hexagon
Area = 12* (8/√3) ft^2 = (96/√3) ft^2
And we can write:
96 = √(96*96) = √9216
Then:
Area = √(9216/3) ft^2 = √(3072) ft^2

Oliver spot frustrated sometimes with his somewhat limited set of red We, and green building bricks. Part way through project, he often machines that transform brick of one colour into a combination of cut of bricks of one particular colour. So he invented some 3D printing bricks of one or more colours, Ench machine can also operate in re The red machine (R) converts I red brick (r) into I blue brick (b) 1 groet brick (g). This process and its reverse are represented by R-1 R bg and be Similarly, for the blue machine (B) we have B B- b Tg and Tg +b. And for the green machine (G) we have G-1 g rb and rb The machines can be used on collections of bricks, performing one con version at a time.

Joe's friends are going to climb a climbing wall and have invited Joe to go with them. Joe is afraid of heights and wants to know how high the climbing wall is before he climbs it. Joe is 5.5 ft tall and at 3:00 pm his shad is 2.75 ft long. At the same time, the shadow of the rock-wall is 35 ft long. How tall is the rock wall?
Answer:
Rock Wall Height = 70ft
Step-by-step explanation:
Joe's height = 5.5 ft , Joe's shadow height = 2.75 ft [At 3.30 pm]
At 3.30 pm , Joe's height : Shadow Radio = 5.5 : 2.75 = 2 : 1
So, Product real height : Shadow height = 2 : 1 [At 3.30 pm]
Rock wall shadow height = 35 ft long
As per Height : Shadow ratio = 2 : 1 . So, rock wall real height = 2 x shadow height = 2 x 35 = 70 ft long

The dollar value of a car is a function, f, of the number of years, t, since the car was purchased. The function is defined by the equation f(t)=12,000(3/4)^t.
A. How much was the car worth when it was purchased? Explain how you know.
B. What is f(2)? What does this tell you about the car?
C. About when was the car worth $6,000? Explain how you know.
Answer:
1.) 12000
2.) 6750
3.) 2.41
Step-by-step explanation:
Given the Equation :
f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t
When, car was purchased, t = 0
t = 0
f(0) = 12000(3/4)^0
= 12000 * 1
= 12000
2.)
f(2) ; this mean the worth of the car after 2 years :
f(2)=12,000(3/4)^t.
12000(3/4)^2
12000 * 0.5625
= 6750
When car will be worth 6000
f(t) = 6000
f(t)=12,000(3/4)^t.
6000 = 12,000(3/4)^t
6000 / 12000 = (3/4)^t
1/2 = (3/4)^t
Take the log of both sides :
Log(0.5) = log(0.75)^t
log(0.5) = tlog(0.75)
- 0.301029 = - 0.124938t
t = - 0.301029 / - 0.124938
t = 2.4094
t = 2.41 years
