Answer:
x=40
Step-by-step explanation:
x + 320 = 360
-320 -320
x = 40
Answer:
x=40
Step-by-step explanation:
So, since the figure has 4 sides, we know that the sum of the interior angles is 360. To check: (n-2)*180=(4-2)*180=28180=360.
That means x equals 360 minus the sum of the other three angles.
100+120+100=320
360-320=40
x=40 degrees

The diagram shows a cuboid of volume V cm3
(a) Show that V = 15 + 16x - x (squared) - 2x (cubed)
Answers
Answer:
Step-by-step explanation:
Length of the cuboid = ((2x + 5) cm
Width of the cuboid = (3 - x) cm
Height of the cuboid = (2x + 5) cm
Since, volume of the cuboid = Length × Width × Height
= (2x + 5)(3 - x)(x + 1)
= [2x(3 - x) + 5(3 - x)](x + 1)
= (6x - 2x² + 15 - 5x)(x + 1)
= (-2x² + x + 15)(x + 1)
= x(-2x² + x + 15) + 1(-2x² + x + 15)
= -2x³ + x² + 15x - 2x² + x + 15
= -2x³ - x² + 16x + 15
≈ 15 + 16x - x² - 2x³
If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?
Answers
Answer: 0.71
Step-by-step explanation:
Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:
P(R) + P(C) = 1
0.29 + P(C) = 1
P(C) = 1 - 0.29
P(C) = 0.71
Therefore, the probability of a cup drink being cola flavour is 0.71.

6/12+8/12+9/12=23/12=1 11/12
Answer:
D. 1 11/12
Step-by-step explanation:
Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.
Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.
Now, multiply your fractions by the numbers they need to get the denominator to 12.
1/2 x 6/6 = 6/12
2/3 x 4/4 = 8/12
3/4 x 3/3 = 9/12
Add your numerators.
6 + 8 + 9 = 23.
Your fraction should look like 23/12.
Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.

Answer:
A) 180 square feet.
Step-by-step explanation:
The two rectangles are congruent, therefore having the same area.
The area of a rectangle, or any quadrilateral for that matter, is Length x Width.
12 * 4 = 48
There are two, so multiply this number by 2 and you get 96.
The formula for a trapezoid's area is height * 1/2 * (base 1 + base 2)
The height given is 6 feet. The 1st base is 10 feet, and the longer base is 10 + 4 + 4, this equals 18
The formula is now
[tex]6 * \frac{1}{2} (18 + 10)\\6 * \frac{1}{2} (28)\\6* 14\\=84[/tex]
Now in total, 84 + 96 = 180.

30. From 55 lb to 24 lb
Answers
Answer:
Decease in weight by 56.4%
Step-by-step explanation:
From 55 lb to 24 lb,
There is a decrease in the weight from 55 lb to 24 lb.
For the percentage decrease in weight,
Change in weight = 55 - 24
= 31 lb
Percentage change in weight = [tex]\frac{\text{Total change}}{\text{Initial value}}\times 100[/tex]
= [tex]\frac{31}{55}\times 100[/tex]
= 56.36%
≈ 56.4%
Therefore, there is a decease in weight by 56.4%.

Let f be differentiable such that f(-2)=3,f(3)=5, f'(-2)=4 and f'(3)=6. Let g be differentiable functions such that g(x)=f^-1 (x) for all x. What is the value of g'(3)
Answers
Answer:
[tex]g'(3)=\frac{1}{4}[/tex]
Step-by-step explanation:
There is a rule in calculus that tells us that:
[tex]g'[f(x)]=\frac{1}{f'(x)}[/tex]
In this case, we know that f(-2)=3, therefore:
g'(3)=g'(f(-2))
So, if we used the rule, we would get that:
[tex]g'[f(-2)]=\frac{1}{f'(-2)}[/tex]
we know that f'(-2)=4, so:
[tex]g'[f(-2)]=\frac{1}{4}[/tex]
or:
[tex]g'[3]=\frac{1}{4}[/tex]

Step-by-step explanation:
Slope equation:

x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
(0,0) (2,6)
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x

Lindas aunt zoe charges her a nominal amount for watching her two children aunt zoe charges $2.50 per day plus $1.75 per hour one day linda paid her aunt $14.75 how many hours did aunt zoe watch the children
Answers
Answer:
7 hours
Step-by-step explanation:
the function of the earning of Zoe = 2.50 + 1.75h
2.5 = base fixed amount
1.75 varies based on the hours
h = hours
2.50 + 1.75h = 14.75
to solve for h
subtract 2.5 from both sides and then divide by 1.75
14.75 - 2.5 = 1.75h
12.25 = 1.75h
h = 7
