If you enter the square root of 93 on a calculator, the answer is 9.64365076099. This is after 9 but before 10.

Answer:

30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

150 = ?+120

Subtract 120 from each side

150-120 = ?

30 = ?

Answer:

[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]

Step-by-step explanation:

According to exterior angle theorem:

The measure of the exterior angle is equal to the sum of non-adjacent interior angles.

So,

< VST = <STU + <SUT

150 = 120 + <SUT

<SUT = 150-120

<SUT = 30 degrees

Answer:

r = -46/3

Step-by-step explanation:

-3(r+2)=40

Distribute

-3r - 6 = 40

Add 6 to each side

-3r-6+6 = 40+6

-3r = 46

Divide by -3

r = 46/-3

r = -46/3

Answer:  2x^2      -16t

               25t         -20

Step-by-step explanation:

Multiply the corresponding terms to find out which answer belongs in each box. For the top left box you would multiply  5t x 4t = 20t^2. For the top right multiply -4 x 4t = -16t. For bottom left box multiply 5t x 5 = 25t and for the bottom right box multiple -4 x 5 = -20.

If you subtract 11.1 from 8.3 you get 2.8

2.8 is your answer :)

Since Peru spends 8.3 and Israel spends 11.1

Subtract that and that's how many more Israel spends on the internet

I took the test on Edge

8 hours

110 miles ................. 5 hours

176 miles ..................x hours

x = 176×5/110 = 880/110 = 8 hours

Answer:

maya drives 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?

We use the rule of three

110 miles -------------> 5 hours

176 miles ------------> ???

So (176 miles × 5 hours) /110 miles

We simplify by 《miles》 because it is in the numerator and the denominator

SO (176×5 hours )/110

= 880 hours / 110

= 8 hours

So she drives 176 miles in 8 hours.

1.1      Factoring:  x2-44  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Answer:

a) 0.2 h

b) 5 cm

Step-by-step explanation:

The given equation is:

[tex] d = 5h [/tex]    (1)

Where:

d: is the depth in centimeters

h: is the time in hours  

a) The hours that takes for 1 cm of snow to accumulate in Harper's yard can be found by solving equation (1) for h and by entering d = 1 cm into the equation:      

[tex]h = \frac{d}{5} = \frac{1}{5} = 0.2 h[/tex]

Hence, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.  

b) The depth in centimeters of snow accumulate per hour is:  

[tex] d = 5h = 5*1 = 5 cm [/tex]

Therefore, 5 cm of snow accumulates per hour.  

I hope it helps you!

Answer:

P = 2 / 25

Step-by-step explanation:

If we assume that the combination of green and pink means, 1 green and 1 pink, then we can say the following:

P = 1 / 25 + 1 / 25

P = 2 / 25

This is because the squares where green and pink intersect only occurs twice.

Hence, the probability is P = 2 / 25.

Cheers.

Answer:

The sum is 1

Step-by-step explanation:

When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.

Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.

Answer:

126 in³

Step-by-step explanation:

Given a cylindrical vase having a diameter (d) of 4 in, and an height (h) of 10 in, the amount of water it would contain can be calculated using:

Volume of cylinder = πr²h

Where,

r = radius = ½ of d = ½*4 = 2 in

h = height = 10 in

Take π as 3.14

Plug in the values into the formula

Volume = 3.14*2²*10 = 3.14*4*10 = 125.6 ≈ 126 in³

Answer:

SO we have to solve this equation:

24p + 12 - 18p = 10 + 2p - 6

First, we will operate what we have in both sides:

24p - 18p + 12 = 10 - 6 + 2p

6p + 12 = 4 + 2p

We substract 2p in both sides and 12 too.

6p + 12 - 2p - 12 = 4 + 2p - 2p - 12

4p = -8

Now, we divide both sides by 4

4p/4 = -8/4

p = -2

The value of p is -2.

The correct option is (B)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

24p +12 - 18p = 10 + 2p - 6

Now, solving for p

6p + 12= 2p + 4

6p - 2p = 4 -12

4p = -8

p= -8/4

p= -2

Hence, the value of p is -2.

[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]

Step-by-step explanation:

To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

[tex]\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}[/tex]

LCM of the denominators,

2 |  25   11    100   24

2 |  25    11     50    12

5 |  25    11     25     6  

5 |    5     11     5      6  

      1      11      1       6

LCM = 2×2×5×5×6×11 = 6600

[tex]\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}[/tex]

   [tex]=\frac{792}{6600}[/tex]

[tex]\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}[/tex]

    [tex]=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}[/tex]

[tex]\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}[/tex]

     [tex]=\frac{594}{6600}[/tex]

[tex]\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}[/tex]

    [tex]=\frac{275\pi }{6600}[/tex]

    [tex]=\frac{864}{6600}[/tex]

Now we can arrange these fractions in the order of greatest to least.

[tex]\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}[/tex]

Answer:

n = 20

Step-by-step explanation:

The number of diagonal that can be drawn in a polygon of n sides is given by :

[tex]D=\dfrac{n(n-3)}{2}[/tex]

If the number of diagonals are 230, then put D = 230 in above formula. So,

[tex]230=\dfrac{n(n-3)}{2}\\\\460=n^2-3n\\\\n^2-3n-460=0[/tex]

It is a quadratic equation, the value of n is equal to 20.

It means that for 230 diagonal, there are 20 sides of the polygon.

Answer:

x + 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of rectangle = 3x + 6

Width of rectangle = 4x – 1

Width of door =..?

A careful observation of the diagram shows that the door is located along the length of rectangular room.

In a rectangle, two sides are equal. Therefore,

x + door + x = 3x + 6

Making door subject of the above formula, we have:

x + door + x = 3x + 6

door + x + x = 3x + 6

door + 2x = 3x + 6

Subtract 2x from both side

door + 2x – 2x = 3x + 6 – 2x

door = 3x – 2x + 6

door = x + 6

Therefore, the width of the door is x + 6
