26 out of 65 as a percentage
How would you do that without a calculator?

Answer:

x = 12

Step-by-step explanation:

[tex] {x}^{2} = {6}^{2} + {( \sqrt{18 \times 6} )}^{2} \\ \\ {x}^{2} = 36 + {( \sqrt{108} )}^{2} \\ \\ {x}^{2} = 36 + 108 \\ \\ {x}^{2} = 144 \\ \\ x = \sqrt{144} \\ \\ x = 12[/tex]

sum of all sides of triangle=180°

7x+13x+16x=180°

x=180°/36

x=5

angle D=7x

=7(5)

D=35°

angle E=13(x)

E=65°

angle F=16x

=16(5)

F=80°

angle D=35°

angle E=65°

Answer :-

9(3+√3) feet

Step by step explanation :-

A triangle is given to us. In which one angle is 30° and length of one side is 18ft ( hypontenuse) .So here we can use trignometric Ratios to find values of rest sides. Let's lable the figure as ∆ABC .

Now here the other angle will be = (90°-30°)=60° .

In ∆ABC ,

=> sin 30 ° = AB / AC

=> 1/2 = AB / 18ft

=> AB = 18ft/2

=> AB = 9ft .

Again In ∆ ABC ,

=> cos 30° = BC / AC

=> √3/2 = BC / 18ft

=> BC = 18 * √3/2 ft

=> BC = 9√3 ft .

Hence the perimeter will be equal to the sum of all sides = ( 18 + 9 + 9√3 ) ft = 27 + 9√3 ft = 9(3+√3) ft .

Answer:

Step-by-step explanation:

Let x be last year's salary.

100%x + 8/100 x = 40120

100x/(100) + 8/100x  = 40120

108x/100 = 40120

1.08x = 40120

x = 40120/1.08

x = 37148.14

Now if you take 8% of  37148.14        =    2971.85

And add it to                                            37148.14

You should get the current earning      40119.99  

You are within a penny of the same answer. This question will not work out evenly because 1.08 does not divide evenly into 40120.

Answer: y=0

Step-by-step explanation:

Mid point of line segment joining (a,b) and (p,q) = [tex](\dfrac{a+p}{2},\dfrac{b+q}{2})[/tex]

Mid point of line segment joining the points (-1,3) and (5,-3) = [tex](\dfrac{-1+5}{2},\dfrac{3-3}{2})[/tex]

[tex]=(\dfrac42,\dfrac02)\\= (2,0)[/tex]

Equation of line passing through (a,b) and (c,d) is given by :-

[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]

Equation of line passing through (2,0) and (0,0) will be:

If a  rectangular water tank can hold 142.5 cubic meters of water its base is 9.5 meters by 5 meters  then the height is 3 meters.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that a rectangular water tank can hold 142.5 cubic meters of water

base is 9.5 meters by 5 meters

We have to find the height of the water tank.

Volume = length × width ×height

142.5 = 9.5×5×height

142.5=47.5 height

Divide both sides by 47.5

142.5/47.5 = height

3 = height

Hence, if a  rectangular water tank can hold 142.5 cubic meters of water its base is 9.5 meters by 5 meters  then the height is 3 meters.

c, because if you're doing a percentage of kids who bring lunches you need to do every grade level and every student to get a proper percentage

We first complete the square.

y=-x^2+2x+1

y=-x^2+2x-1+1+1

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

The maximum point is (1,2) since -1 in ( ) meant 1 unit to the right and +2 meant 2 units up.

The maximum point is (1,2) but the maximum value means the y value which is simply just 2.

Answer:

Step-by-step explanation:

Circumference is distance round a figure. When diameter is trippled, the circumference will also tripple.

Here is a proof

Take the moon to have circular shape and has diameter d

Circumference is given by C=πd

When the new diameter is trippled, diameter will be 3d and the new circumference will be

C=π3d=3πd

Evidently, the new circumference is three times the original circumference. Therefore, for this case, the new circumference will be 3 times the original

[tex]\frac25[/tex] and [tex]-\frac25[/tex]

Step-by-step explanation:

Hello!

The square root method is the process of square rooting both sides of the equation.

When you square root a number that is being squared (x^2), it is the absolute value of that number. Meaning that you keep a plus or minus sign on the other side.

The roots of the equation are [tex]\frac25[/tex] and [tex]-\frac25[/tex].

Answer:

j = -15/8

Step-by-step explanation:

Here, we want to find the value of j

-3/4j = 3/5 - 1/5

-3/4j = 2/5

4j * 2 = -3 * 5

8j = -15

j = -15/8

Answer: x is doubled.

Step-by-step explanation:

A proportional relationship between x and y is written as:

y = k*x

where k is called the constant of proportionality.

In this case, we know that we have a proportional relationship between z and x^3

Then:

z = k*x^3

What will happen to x when z is 8 times greater?

Let's rewrite this equation for two new quantities, z' and x'

z' = k*(x')^3

Now we need to replace z' by 8*z, then:

8*z =  k*(x')^3

We want to find a relationship between x' and x.

And by the first relationship, we know that:

z =  k*x^3

Then we can replace this in the equation "8*z =  k*(x')^3" to get:

8*(k*x^3) =  k*(x')^3

8*k*x^3 = k*(x')^3

Now we can divide both sides by k, so we get:

8*x^3 = (x')^3

Now we can apply the cubic root to both sides, to get:

∛(8*x^3) = ∛(x')^3

∛(8)*x = x'

2*x = x'

Then when we increase the value of z 8 times, the value of x will be doubled.
