You can't really do this without changing the value of the number.

But to do this, just multiply the denominator, 10, by 10, because 10 x 10 = 100.
Do not multiply 8 by 10 or anything. So, now your fraction is 8/100, or 0.08, or 8 hundredths.

Solution 1

$8x+47=8(x+5)
$
$8x+47=8x+40$
$8x+47-47=8x+40-47$
$8x=8x-7$
$8x-8x=8x-7-8x$
$0=-7$
there is no solutions
Hope this helps :)

Solution 2

8x + 47 = 8x + 40

Question

98 POINTS PLEASE HELP --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Determine the standard form of the equation for the circle With center (h,k)=(-5,1/2) and radius r=1 A) (x-5)^2 + (y + 1/2)^2 = 1 B) (x-5) + (y - 1/2) = 1 C) (x+5)^2 + (y - 1/2)^2 = 1 D) (x+5)^5 + (y- 1/2)^2 = 105/2

Solution 1

The standard form of a circle is $(x-h)^2+(y-k)^2=r^2$ . We will fill in our h, k and r accordingly. $(x-(-5))^2+(y- \frac{1}{2})^2=1^2$ which simplifies down to $(x+5)^2+(y- \frac{1}{2})^2=1$ choice C. There you go!

Solution 2

Hello!

I believe the answer is C) (x+5)^2 + (y - 1/2)^2 = 1.

I hope it helps!

Question

Which event is considered neither likely nor unlikely? A. rolling a number greater than one on a six-sided number cube B. rolling a 1 on a six-sided number cube C. getting heads when flipping a coin D. choosing a X, Y, or Z from a bag containing all letters in the alphabet

Solution 1

Hey there

The answer is D.
choosing a X, Y, or Z from a bag containing all letters in the alphabet.

There are 46 different alphabets.
You have 3/46 chances
6% out of 100 of picking those letters

Solution 2

A.) it is possible to roll a number greater than 1 on a six sided number cube. - So it is likely.

B) It is possible to roll a 1. - So it is likely.

C) It is possible to get a heads when flipping a coin. - So it is likely.

D) It is possible to choose a X, Y or Z from the alphabets. - So it is likely.

Am sorry did not see any one that is neither likely nor unlikely.

There is likelihood in each of the Event, but to some varying degree.

I hope this helps.

Question

joni translates a right triangle 2 units down and 4 units to the right. How does the orientation of the image of the triangle compare with the orientation of the preimage?I will make it 100 pts if you help

Solution 1

Answer:

The orientation stays the same

Step-by-step explanation:

we know that

A translation is a transformation that slides a figure along a straight line. No change to size, shape or orientation of the figure.

therefore

In this problem

The orientation is not affected

The orientation stays the same

Question

If P(blue) is 0.3, what is P(not blue)?\ A. 0.3 B. 0.5 C. 0.6 D. 0.7

Solution 1

Probability of Event Occurring + Probability of Event not occurring = 1.

Therefore:

P(blue) + P(not blue) = 1.

Therefore P(not blue) = 1 - P(blue)

P(blue) = 0.3

P(not blue) = 1 - P(blue) =1 - 0.3 = 0.7

P(not blue) = 0.7

Option D.

Question

Which of the following equations could be used to solve the given equation? 9x + 26 + 7x - 17 = 2x + (-3x) + 5x 16x + 9 = 0 16x + 9 = 4x 16x + 11 = 4x

Solution 1

Answer: The correct option is (B) $16x+9=4x.$

Step-by-step explanation: We are given to select the correct equation that could be used to solve the following equation :

$9x+26+7x-17=2x+(-3x)+5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the correct equation, we need to simplify the given equation (i).

From equation (i), we get

$9x+26+7x-17=2x+(-3x)+5x\\\\\Rightarrow (9+7)x+(26-17)=2x-3x+5x\\\\\Rightarrow 16x+9=(2-3+5)x\\\\\Rightarrow 16x+9=4x.$

Thus, the required equation is $16x+9=4x.$

Option (B) is CORRECT.

Solution 2

If we simplify like terms on left and right sides we gwt

16x + 9 = 4x

Its B

Question

alyssa wants to build a fence around her garden to keep deer and rabbits out. the length of the fence must be at least 50 ft, but she only has 140 ft for entire perimeter

Solution 1

The perimeter of a rectangle is twice the sum of the length and width:
P = 2(L + W)
Since we are given L >= 50 ft and P = 140 ft:
140 >= 2(50 + W)
70 >= 50 + W
20 >= W
Therefore, the width is less than or equal to 20 ft.

(The maximum area is 50 x 20 = 1000 ft^2.)

Question

HELP ME PLEASE I DONT UNDERSTAND THIS PROBLEM!!!!! Worth 20PT a ball is thrown with a slingshot at a velocity of 100 ft/sec at an angle 21 above the ground from a height of 5ft approximately how long does it take for the ball to hit the ground? acceleration due to gravity is 32 ft/s^2

Solution 1

It takes approximately 6.3 seconds to hit the ground.

We use the equation h(t)=-1/2gt²+v₀t+h₀ to set this up. g is the acceleration due to gravity, v₀ is the initial velocity and h₀ is the initial height:
h(t) = -1/2(32)t² + 100t + 5
h(t) = -16t² + 100t + 5

We will use the quadratic formula to solve this:
$t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
\\
\\=\frac{-100\pm\sqrt{100^2-4(-16)(5)}}{2(-16)}
\\
\\=\frac{-100\pm\sqrt{10000--320}}{-32}
\\
\\=\frac{-100\pm\sqrt{10320}}{-32}
\\
\\=\frac{-100\pm101.59}{-32}
\\
\\=\frac{-100+101.59}{-32}\text{ or }\frac{-100-101.59}{-32}
\\
\\=\frac{1.59}{-32}\text{ or }\frac{-201.59}{-32}
\\
\\=-0.05\text{ or }6.3$

Since a negative amount of time makes no sense, the answer is 6.3.

Solution 2

Answer:

D) 2.37 seconds

Step-by-step explanation:

Took the test and got it wrong.
