Answer:
229.2
Step-by-step explanation:
Remark
There's a lot in this question. The x is not just any x. It is defined and limited by its relationship with the sine function.
The Sin is defined as Opposite over Hypotenuse in a right triangle. The 670 is the Hypotenuse. You know that by the definition of Sine.
So one thing you should always keep in mind: the x because of where it is in the definition, will always be smaller than the Hypotenuse. So you should get a value less than 670.
Formula
Just as you have it
Sin(20) = x / 670
Solution
Multiply both sides by 570
670 * sin(20) = x
sin(20) = 0.3420
x = 670 * 0.3420
x = 229.2

What is the two fifths of the collection pilers, hammers, wrenches, saws.
Answer:
Pliers
Step-by-step explanation:
From the picture attached,
Number of pliers = 4
Number of hammers = 2
Number of wrenches = 2
Number of saws = 2
Total collection of tools = 4 + 2 + 2 + 2 = 10
Since, two fifth means,
[tex]\frac{2}{5}=\frac{2\times 2}{5\times 2}[/tex]
[tex]\frac{2}{5}=\frac{4}{10}[/tex]
That means tool with 4 counts out of total 10 tools will be the answer.
And the answer is pliers.

A squirrel is trying to prepare for the winter. As it gets closer to winter, he starts to collect a lot of acorns. He collects 6 the first day and doubles the amount he collects each day. What is an equation that represents this situation?
Answer:
6x + 12x + 24x + 48x.....
Step-by-step explanation:
A squirrel Is preparing for winter
It begins to collect acorns
Let x represent the acorns
He collects 6 the first day and doubles the amount he collects each day
The equation can be represented as
6x + 12x + 24x + 48x........

A cone-shaped water tank is completely filled. The tank has a depth of 12 feet and a radius of 29 feet. A pump removes water from the tank at a rate of 1000 cubic feet per hour.
What is the volume of water in the tank before the water is pumped out?
Use 3.14 to approximate π and express your final answer to the nearest hundredth.
How many hours will it take to drain all the water?
Answer:
Volume = 10562.96 cu ft
10.56 hr. to drain all the water
Step-by-step explanation:
V = 1/3Bh B = area of the base h = height
The base is a circle, so [tex]B = \pi r^{2}[/tex]
[tex]V = \frac{1}{3} (3.14) (29^{2})(12)[/tex] = 10562.96 cu ft
10562.96/1000 = 10.56 hr.
Find the value of x, image attached below
Answer:
x = 10
Step-by-step explanation:
Sum of angles in a triangle is 180° , so
35° + (5x + 7)° + (9x - 2)° = 180°
The value of x can now be found by solving the linear equation.
5x + 9x + 35 + 7 - 2 = 180
14x + 40 = 180
14x = 180 - 40
14x = 140
x = 140/14
x = 10

add all the marbles (20) and that’s the total. then however many marbles in the color that’s the top number in the fraction. divide the top number by the bottom number to get the decimal and move the decimal 2 spaces to the right to get the percent.
solve with substitution 3x + y =19 -6x - 5 = y
Answer:
x=-8
Step-by-step explanation:
3x + y =19
-6x - 5 = y
3x + y =19
-6x -y=5
-3x=24
x=-8
y= -6x -5
y=48-5=43

Fourteen pounds less than eight times the pounds of chocolate Jo got for her birthday is three more than four times the pounds of chocolate Jo got. How much chocolate did Jo get for her birthday?
Answer:
Total chocolates Jo bought for her birthday = 4.25 pounds
Step-by-step explanation:
Given - Fourteen pounds less than eight times the pounds of chocolate Jo got for her birthday is three more than four times the pounds of chocolate Jo got.
To find - How much chocolate did Jo get for her birthday?
Proof -
Let Jo bought total chocolates = x pounds
Then,
8x - 14 = 4x + 3
⇒8x - 4x = 3 + 14
⇒4x = 17
⇒x = [tex]\frac{17}{4}[/tex] = 4.25
∴ we get
Total chocolates Jo bought for her birthday = 4.25 pounds
Justification -
8(4.25) - 14 = 4(4.25) + 3
⇒34 - 14 = 17 + 3
⇒20 = 20
Satisfied.

What is the volume of the prism?
*Do NOT round your answer.
Answer:
300 in³
Step-by-step explanation:
Hello There!
The prism shown is a rectangular prism
The formula for volume of a rectangular prism is
[tex]Volume=lwh[/tex]
where l = length w = width h = height
so we are given all of the dimensions so to find the volume all we have to do is plug in the values into the formula
so
[tex]V=10*5*6\\10*5=50\\50*6=300\\V=300 in^3[/tex]
Answer:
the volume of the prism=length ×breadth ×height =10×5×6=300in³

Answer: 90
Step-by-step explanation:
Answer:
90m
Step-by-step explanation:
you have to cross multiply.
1) multiply (12 * 15) and multiply 2 * X)
2) you get 180 = 2x
3) to get X alone divide 180 by 2 and you will get 90meters
