How to simplify -(-7y+12)

Mathematics
1 answer:
faust18 [17]3 years ago
7 0
-(-7y + 12) = 7y - 12
u are distributing the -sign through the parenthesis...so u take the number outside of the parenthesis (and if it just a sign, the number is 1)...and u multiply it by everything in the parenthesis.
-1(-7y + 12) = -1 * -7y + (-1) * 12 = 7y + (-12) = 7y - 12

Change the decimal to fraction form or mixed number form and reduce if possible 73.437
harina [27]

Answer:

73.437= 74 437/1000

Step-by-step explanation:

73.437 to fraction.

Let's acknowledge the presence of a decimal and how many digit we have after the decimal point.

Actually, the numbers after the decimal point will determine the amount of 10s to be divided with.

What I'm saying is this

73.437= 74 437/1000

In this case, 437 is a prime number

So

73.437= 74 437/1000

If an isosceles triangle ABC has a vertex B, and AB=6×+3, BC<br> BC=8x-1, and AC=10x-10, find x
saw5 [17]

Using the given information, the value of x is 2

<h3>Calculating the length of the leg of an isosceles triangle</h3>

From the question, we are to determine the value of x

From the given information,

The isosceles triangle ABC has its vertex at B

If the vertex is at B, then we can conclude that

AB = BC (<em>Legs of an isosceles triangle are equal a</em>)

Also, from the given information,

AB = 6×+3

BC = 8x-1

Thus,

6x + 3 = 8x - 1

Collect like terms

3 + 1 = 8x - 6x

4 = 2x

2x = 4

∴ x = 4/2

x = 2

Hence, the value of x is 2

Solve the problem.
Aleksandr [31]

Answer:

The given equation is

\theta = cot^{-1}(\frac{r}{h} )

Which is the definition of the angle of repose.

<em>Remember that the angle of repose refers to the angle between the horizontal plane and the inclined side of the cone formed when we allow to fall freely granular materials.</em>

We know by given

h=19\\r=\frac{d}{2}=\frac{30}{2}=15

Replacing these values, we have

\theta = cot^{-1}(\frac{15}{19} ) \approx 38.29 \°

Therefore, the angle of repose is 38.29° approximately.

Now, if the base diameter is 104 feet, the height would be

38.29 = cot^{-1}(\frac{52}{h}\\tan(38.29)=\frac{52}{h}\\ h=\frac{52}{0.79} \approx 65.8

Therefore, the height would be 65.8 feet, assuming that the angle of repose is the same.
