5h + 2(11-h) = -5

5h +2*11 +2*(-h) = -5

5h +22 -2h = -5

3h + 22 = -5

3h = -5 -22

3h = -27

------

Therefore:

h=(-9), as 3 *(-9) = -27

5h+2(11−h)=−5

Simplify:

5h+2(11−h)=−5

5h+(2)(11)+(2)(−h)=−5(Distribute)

5h+22+−2h=−5

(5h+−2h)+(22)=−5(Combine Like Terms)


3h+22=−5

Subtract 22 from both sides.

3h+22−22=−5−22

3h=−27

Divide both sides by 3.

3h/3=−27/3

h=−9

If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).
denpristay [2]

Answer:

VYX=84.3in

Step-by-step explanation:

Given

YV = 28in

\angle WZX = 15^\circ

See attachment

Required

Determine the length of VYX

First, calculate the major angle VZX

\theta = \angle VZX = 360 - \angle WZX

\theta = \angle VZX = 360 - 15

\theta = \angle VZX = 345

\theta = 345

The length of arc VYX, is:

L=\frac{\theta}{360} * 2\pi r

Where

r = \frac{1}{2} * Diameter

r = \frac{1}{2} * YV

r = \frac{1}{2} * 28

r = 14

So:

L=\frac{\theta}{360} * 2\pi r

L=\frac{345}{360} * 2 * \frac{22}{7} *14

L=\frac{345}{360} * 2 * 22 *2

L=\frac{345* 2 * 22 *2}{360}

L=\frac{30360}{360}

L=84.3in

Hence, the length of VYX is:

VYX=84.3in

If the volume of sand is increasing at a constant rate, is the height increasing at a constant rate? Explain.
AysviL [449]
It does not necessarily mean that the height will rise although I it could rise.this is because volume is what is inside your shape. It could spread out more and have more volume. If you think I'm smart let me tell you I'm only in 4th grade not bragging

How to you solve -15=y-62
sdas [7]
First move the (Y) to the other side of the equal sign,
- y - 15 = - 62
Then subtract add (15) on both sides
- y = - 47
Since a variable can't be negative just divide by (-1) on both sides,
\frac{ - y}{ - 1} = \frac{ - 47}{ - 1}
The answer would be,
y = 47
Hope this helped

Keri is simplifying 5·10^−3.
11111nata11111 [884]

Answer:

1. D

2. A

Step-by-step explanation:

Q1. Kerry is simplifying 5\cdot 10^{-3}

By the definition of negative powers,

a^{-n}=\dfrac{1}{a^n}

Hence,

10^{-3}=\dfrac{1}{10^3}

So, the first step in simplifying the expression is

5\cdot 10^{-3}=5\cdot \dfrac{1}{10^3}

Q2. Given the expression

\dfrac{8}{10^{-2}}

First, use the definition of negative powers:

10^{-2}=\dfrac{1}{10^2}

Thus,

\dfrac{8}{10^-2}=\dfrac{8}{\frac{1}{10^2}}=8\cdot 10^2=8\cdot 100=800
