find the value of given expression

[tex] \sqrt{230 - 5} [/tex]
​

Answer: 50 hours

Step-by-step explanation:

Given

The volume of a swimming pool is [tex]25,000[/tex] gallon

It takes 30 minutes to fill [tex]250\ \text{gallons}[/tex]

Using Unitary method

[tex]\Rightarrow 250\ \text{gallon takes}\rightarrow 30\ \text{minutes}\\\Rightarrow 1\ \text{gallon takes}\rightarrow \dfrac{30}{250}\\\\\Rightarrow 25,000\ \text{gallon}\rightarrow \dfrac{30}{250}\times 25,000=3000\ \text{minutes or 50 hours}[/tex]

Answer:

m<Y = 68°

Step-by-step explanation:

A tangent drawn to a circle makes a 90° angle with the radius that intersects it at the point of tangency. That means that m<X = 90°.

The sum of the measures of the angles of a triangle is 180°.

m<X + m<Y + m<Z = 180

90 + m<Y + 22 = 180

m<Y + 112 = 180

m<Y = 180 - 112

m<Y = 68

Answer:

  3

Step-by-step explanation:

The ratio is ...

  f(x+1)/f(x) = (10·3^(x+1))/(10·3^x) = 3^(x+1-x) = 3^1 = 3

The common ratio is 3.

As you may have noticed, it is the base of the exponential term.

Answer:

$ 50

Step-by-step explanation:

sp = mp - discount percent of mp

or, 42 = mp - 16/100 * mp

or, 42 = 84 mp / 100

so, mp = 50

Answer:

100 - 84

50 - 42

Answer:

False

Step-by-step explanation:

It has two parts that is separated by a minus.

Answer:

1) 189.25 square inches

2) 21 square feet

Step-by-step explanation:

1) In order to find the area of a semicircle, you use  (πr^2)/2. When you plug in 3.14 as pi and 5 as your radius, you'll get 39.25. The area of the rectangle is base x height which is 10 x 15/150. 150 + 39.25 = 189.25

2) If you draw a vertical line that is parallel to the 2 feet measure, you'll have two rectangles with areas (5x3) and (3x2). 15 + 6 = 21

Answer:

Answer:

The right answer is 8 hope I helped

Answer:

It's actually B

Step-by-step explanation:

The measures of the sides are x , x , and x√2 . In a 45°−45°−90° triangle, the length of the hypotenuse is √2 times the length of a leg. To see why this is so, note that by the Converse of the Pythagorean Theorem , these values make the triangle a right triangle.

So x = 4 in this example and the side measures would be 4, 4, and 4√2 which is B

Answer:

-5/13<x<0

Step-by-step explanation:

5/x+6<-7

subtract 6 from both sides

5/x+6-6<-7-6

5/x<-13

since it is just like a normal equation with an equals sign you can still switch the -13 and x to get

-5/13<x<0

Hope that helps :)

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:

4.82 x 10^-4

Step-by-step explanation:

8.2 x 10^-4 + .0004= enter into calculator

.000482, move decimal behind first whole number and count places

it moves 4 spaces and because it starts in front of the number your exponent is negative

A newspaper and magazine cost 220 together the newspaper cost 140 less than the magazine, then the cost of magazine is 180 and the cost of newspaper is 40.

Two or more expressions with an Equal sign is called as Equation.

Given,

A newspaper and magazine cost 220

the newspaper cost is 140  less than the magazine

Let x be the cost of magazine

x-140 is the cost of newspaper

x+x-140=220

2x-140=220

Add 140 on both the sides

2x=220+140

2x=360

Divide both sides by 2

x=180

and x-140=180-140=40

Hence, the cost of magazine is 180 and the cost of newspaper is 40.
