how do I solve this?

Answer:

[tex]\sqrt 10y[/tex]

Step-by-step explanation:

10*[tex]\sqrt{y}[/tex] is [tex]\sqrt 10y[/tex]

[tex]\sqrt{100y}[/tex]

Step-by-step explanation:

Recall that

[tex]10 = \sqrt{100}[/tex]

So we can write our original expression as

[tex]10\sqrt{y} = \sqrt{100}\sqrt{y}[/tex]

[tex]\;\;\;\;\;\;\;\;\;=\sqrt{100y}[/tex]

Answer:

x<-9

Step-by-step explanation:

subtract the 7x from the right side to bring it over to the left side to get:

2x-7<-25

then add the 7 from the left side to bring it over to the right side to get:

2x<-18 and then divide both sides by 2 to get the final inequality to be:

x<-9

Therefore, the solved inequality is x < -9.

Answer:

y=25x+1150

Step-by-step explanation:

1425-1275=150

150/6=25 so 25 dollars per month

1275-5(25)

1275-125=1150

y=25x+1150

Answer:

3b

Step-by-step explanation:

The mean price goes between $ 41.16 and $ 42.84, so a value of $ 48 is unusually high.

Since the average price of an item is $ 42 with a standard deviation of $ 3, to find a 98% confidence interval about the mean, and determine if a value of X = 48 is unusually high or if it is normal, the following calculations should be done:

Therefore, as the mean price goes between $ 41.16 and $ 42.84, a value of $ 48 is unusually high.

Step-by-step explanation:

Answer:

x = 21

Step-by-step explanation:

2x+78 = 5x+15,

because corresponding angles will allow (2x+78) to move diagonally from 5x+15.

from built geometry knowledge,

angles diagonal from one another equal,

because (example) the angle above it would be 180-(2x+78),

then 5x+15 = 180 - [180-(2x+78)], which would ultimately be 5x+15 = 2x+78.

so, 2x+78 = 5x+15

78-15 = 5x-2x

63 = 3x

Answer:

-7/2

Step-by-step explanation:

-4(-2u+3)-u=3(u-7)-5

8u-12-u=3u-21-5

8u-u-12=3u-26

7u-12=3u-26

7u-3u-12=-26

4u-12=-26

4u=-26+12

4u=-14

u=-14/4

simplify

u=-7/2

Answer:

u = - 3.5

Step-by-step explanation:

Before solving this you have to know that,

(-) × (-) = (+)

(-) × (+) = (-)

(+) × (+) = (+)

Let us solve now.

[tex]-4(-2u+3)-u=3(u-7)-5[/tex]

[tex]8u-12-u=3u-21-5[/tex]

[tex]7u-12=3u-26[/tex]

[tex]7u-3u=12-26[/tex]

[tex]4u=-14[/tex]

[tex]\frac{4u}{4} = \frac{-14}{4}[/tex]

[tex]u=-3.5[/tex]

True or false, depending on the specifics. True, because the gravity makes it go to the ground. False, because gravity is always working, so you don't need to throw the ball. However since it doesn't say that it only happens when you throw it. The answer should be true.

Answer:

x=9

Step-by-step explanation:

since the triangles are similar, the sides are all in proportion. This means that:

[tex] \frac{uw}{eg} = \frac{uv}{fg} [/tex]

Now we can just sub in the sides:

[tex] \frac{91}{13} = \frac{56}{x - 1} [/tex]

simplify the first fraction

[tex] \frac{7}{1} = \frac{56}{x - 1} [/tex]

Now we can cross multiply

56=7(x-1)

56=7x-7

63=7x

Therefore:

×=9

Answer:

9π + 18

Step-by-step explanation:

The circumference of a circle is pi times diameter, so 9 x 2 = 18 inches, which is the diameter. That will be the flat side of the semicircle. Then the circumference of the whole circle will be 18π. To find the curved side of the semi-circle, divide this by 2, so you get 9π. Therefore the answer is 9π + 18. The rough answer to 3 decimal places is 46.274

Answer:

  10,4%

Step-by-step explanation:

The percentage change is found from ...

  (amount of change)/(original amount) × 100%

  (17,90 -16,22)/(16,22) × 100% = 1,68/16,22 × 100% ≈ 10,358% ≈ 10,4%

Answer:

Step-by-step explanation:

Use law of cosines

c² = a² + b² - 2abcosθ

cosθ = (c² - a² - b²) / -2ab

c = length of AC = √(8 - 5)² + (4 - (-5))² = √90

b = length of AB = √(8 - 6)² + (4 - 3)² = √5

a = length of BC = √(6 - 5)² + (3 - (-5))² = √65

cosθ = (√90² - √65² - √5²) / -2√65√5

cosθ = 20 / -36.05551...

cosθ = - 0.5547001

θ = 123.69°
