Answer:

1.05

Step-by-step explanation:

100% is 1.0, therefore 105% will be 1.05.

Explanation:

Think of 105% as 105.0%

Now remove the percent sign to get 105.0

Lastly, move the decimal point two spots to the left to get to 1.05

Percentages that are over 100% convert to decimal values larger than 1; on the flip side, percentages that are under 100% are between 0 and 1.

More Examples:

76% = 0.76

18% = 0.18

255% = 2.55

sqrt(9)

-sqrt(9)

Step-by-step explanation:

What number multiplied by itself will give you 9

3*3 =9

-3*-3 =9

sqrt(9) * sqrt(9) = sqrt(81) = 9

-sqrt(9) * -sqrt(9) = + sqrt(81) =9

Answer:

[tex] - 3[/tex]

[tex] \sqrt 9[/tex]

[tex] - \sqrt 9[/tex]

Step-by-step explanation:

[tex] {x}^{2} = 9 \\ \\ x = \pm \sqrt{9}\\ \\ x = - \sqrt{9}, \:x = \sqrt{9}\\ \\ x = - {3} \: \: x = {3} [/tex]

Answer:

(x + 2)^2 + (y + 5)^2 = 1

Step-by-step explanation:

Since this circle is centered at (-2, -5), we have to add values within the squares. The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

So -2 is h and -5 is k. Substituting that in we get:

(x + 2)^2 + (y + 5)^2 = r^2

We are given the radius is 1, and one squared is one, so the final equation is:

(x + 2)^2 + (y + 5)^2 = 1

Answer:

5 + 2q = 15

Step-by-step explanation:

The perimeter is 4 + 2 + q + (q - 1) = 15.

Add 4 + 2 then subtract the sum from both sides.

q + (q - 1) = 9

This can be simplified further by adding the "q" variables together.

2q - 1 = 9

Add 1 to both sides.

2q = 10

Divide both sides by 2 to isolate q.

q = 5

Answer:

y=7/3x²-13/3x+2

Step-by-step explanation:

Determine the value of c:

y=ax²+bx+c

2=a(0)²+b(0)+c

2=c

Substitute (1,0) into the quadratic and create an equation with a and b:

y=ax²+bx+2

0=a(1)²+b(1)+2

0=a+b+2

-2=a+b

Do the same with (3,10) to get a second equation:

y=ax²+bx+2

10=a(3)²+b(3)+2

10=9a+3b+2

8=9a+3b

Set the two equations equal to each other and solve for a and b:

-2=a+b

8=9a+3b

Multiply first equation by 3 and eliminate b to find a:

 -6=3a+3b

- (8=9a+3b)

_______

-14=-6a

14/6=a

7/3=a

Substitute 7/3=a into the first equation:

-2=7/3+b

-2-(7/3)=b

-13/3=b

Final equation:

y=7/3x²-13/3x+2

Answer:

Hence for a patio with Dimension

Length=12.5 feet

Width=9.5 feet

2.4 bags of concrete mix  is needed

Step-by-step explanation:

The question is not complete, there is not attachment showing the dimension of the patio

Say the dimension of the patio is

Length=12.5 feet

Width=9.5 feet

Area= Length* Width

Area= 12.5*9.5

Area= 118.75 square feet

One bag of concrete mix will cover 50 square feet

Hence x bags will cover  118.75 square feet

cross multiply

50x= 118.75*1

x= 118.75/50

x= 2.4 bags

Answer:

-972

Step-by-step explanation:

The next number in the sequence would be the previous number multiplied by 3.

-4*3 = -12

-12*3 = -36

-36*3 = -108

-108*3 = -324

-324*3= -972

Answer:

The second test result will be lower and more sensitive to changes than the first test result and it will better test the efficacy of the PSA screening test

Step-by-step explanation:

The evaluation the epidemiologist are planning = Prostrate Specific Antigen, PSA, screening test

The given difference between the first and second study = The age range of the study group

The age range of the first study = 60 to 75 years

The age range of the second study = 44 to 59

The prevalence of prostrate cancer in men 44 to 59 years of age < The prevalence of prostrate cancer in men 60 to 75 years of age

Therefore, due to the low prevalence, the result of the second test will be more sensitive than the result of the first test.

Answer:

Step-by-step explanation:

Since it's a 45-45-90 degree triangle, the base and the leg will be the same length. So from there, you just use the Pythagorean theorem and do [tex]5^{2} +5^{2} =m^{2} \\[/tex]

[tex]50=m^{2}[/tex]

and m is [tex]5\sqrt 2[/tex]

Answer:

7 -  Yes

4 - Yes

13 - No

9 - No

Step-by-step explanation:

43 + 7 = 50

52 > 50

43 + 4 = 47

52 > 47

43 + 13 = 56

56 is not less than 52

43 + 9 = 52

52 = 52

Answer:

The volume of the prism is 60 m³.

Step-by-step explanation:

Given that,

The length of the prism is 4 m

The width of the prism is 5 m

The height of the prism is 3 m

The volume of prism is given by the formula as follows :

V = lbh

Put all the values,

V = 4 m × 3 m × 5 m

= 60 m³

Hence, the volume of the prism is 60 m³.

Answer:

[tex] - 0.25881904[/tex]

Step-by-step explanation:

Use the identity

[tex] \sin( - x) = - \sin(x) [/tex]

so

[tex] \sin( - \frac{\pi}{12} ) = - \sin( \frac{\pi}{12} ) [/tex]

Use angle subtraction trig formula

[tex] \sin(x - y) = \sin(x) \cos(y) - \cos(x) \sin(y) [/tex]

In order to get pi/12, we can subtract

pi/4 and pi/6.

[tex] \sin( \frac{\pi}{4} - \frac{\pi}{6} ) = \sin( \frac{\pi}{4} ) \cos( \frac{\pi}{6} ) - \cos( \frac{\pi}{4} ) \sin( \frac{\pi}{6} ) [/tex]

Simplify.

[tex] (\frac{ \sqrt{2} }{2} \times \frac{ \sqrt{3} }{2}) - ( \frac{ \sqrt{2} }{2} \times \frac{1}{2} )[/tex]

[tex] \frac{ \sqrt{6} }{4} - \frac{ \sqrt{2} }{4} [/tex]

[tex] \frac{ \sqrt{6} - \sqrt{2} }{4} [/tex]

which is about

[tex]0.25881904[/tex]

Remeber our sin is negative so our answer is

[tex] - 0.25881904[/tex]
