Can someone please explain how I get the answer to this? I just need an explanation/answer, please.

An isosceles triangle has an angle that measures 132°. Which other angles could be in that isosceles triangle? Choose all that apply.

A: 132
B: 63
C: 24
D: 73

Answer: 5 m

Step-by-step explanation:  

Double the area to get 35. then think what two number multiply to get 35 that are also 2 apart.  7 x 5.  So 7 is the height and 5 is the base.  

Check answer:  A = 1/2xbxh

                               A = 1/2 x 7 x 5

                               A =  1/2 x 35

                               A = 17.5 sq m

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:

ans 3

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

Answer:

x=2

divide 8 by all terms

x = 2 + [tex]\frac{y}{2}[/tex]

Insert x in second equation

8(2+y/2)+4y=16

[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 :-

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 .

Look at the denominator. Diego did not multiply 4 times 3. He simply carried 4 into the product.

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.

Answer:

√41

Step-by-step explanation:

Here we want to find the value of AC

A = (-4,0)

C = (1,4)

The distance formula is;

D = √(y2-y1)^2 + (x2-x1)^2

D = √(4-0)^2 + (1-(-4)^2

D = √4^2 + 5^2

D = √(16+25)

D = √41

Answer:

-2

Step-by-step explanation:

You can see that when x goes up by 1, y goes down by 2. This means the rate of change is -2

Answer:

The rate of change is -2

Step-by-step explanation:

Take any two points from the graph. (0,-4) and (-2,0). Plug them into the equation y2-y1/x2-x1. In this case the equation would be 0--4/-2-0. Simplify this and get 0+4/-2-0. Simplify again and get 4/-2 which is -2

Therefore the rate of change is -2

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.
