The area of a right triangle is 39.6cm2 , and the base of the triangle is 12in . Which of the following values is the height of the triangle?

Answer:   [tex]7\frac{2}{3}[/tex]

Step-by-step explanation:

[tex]\frac{1}{2} (x-5)=\frac{4}{3} \\[/tex]

Multiply both sides by 2

[tex]2(\frac{1}{2} (x-5))= \frac{4}{3} (2)[/tex]

[tex]x-5=\frac{8}{3} \\x-5+5 =\frac{8}{3} +5\\x=7\frac{2}{3}[/tex]

Answer:

1/2(x-5) =4/3

X-5=4/3÷1/2

X-5=8/3

X=8/3+5

X=23/3

Answer:

160 acres

Step-by-step explanation:

Given data

Total Amount of land= 280 Acres

Ratio=4:3

Total part = 4+3= 7

Applying the part to all method

let AI receive x acres

Then

4/7= x/280

cross multiply

7x= 280*4

7x=1120

x= 1120/7

x= 160

Hence AI will receive 160 acres

Answer:

[tex]\Huge\boxed{x=11.8}[/tex]

Step-by-step explanation:

Hello There

cos = adjacent divided by hypotenuse

the adjacent side of the angle that has a measure of 49 is x and the hypotenuse is 18

so

[tex]cos49=\frac{x}{18}[/tex]

once again we want to isolate the variable using inverse operations

to get rid of the 18 we multiply each side by 18

[tex]\frac{x}{18} *=x\\cos49*18=18cos49[/tex]

we're left with

[tex]x=18cos49[/tex]

now we let the calculator do the rest of the work

we end up with

[tex]x=11.80906252[/tex]

our final step would be to round to the nearest tenth

so we can conclude that the x = 11.8

Answer:

x+35/5=2

x+35=10

x=-25

Answer:

[tex]\frac{1}{5} x[/tex]+7=2, x=-25

[tex]\frac{m}{7} -7=3[/tex], m= 105

[tex]\frac{3}{5} x+7=-20, x= -45[/tex]

[tex]-\frac{2}{7} t+5=17, t=-42[/tex]

4.9x+4.2=9.1, x=1

Explanation for last two:

[tex]-\frac{2}{7}t+5=17[/tex]  

Step 1: Subtract 5 from both sides.

[tex]\frac{-2}{7} t+5-5=17-5[/tex]

[tex]\frac{-2}{7} t=12[/tex]

Step 2: Multiply both sides by 7/(-2).

[tex](\frac{7}{-2} )*( \frac{-2}{7}t )= (\frac{7}{-2} )*(12)[/tex]

t=−42

4.9x+4.2=9.1

Step 1: Subtract 4.2 from both sides.

4.9x+4.2−4.2=9.1−4.2

4.9x=4.9

Step 2: Divide both sides by 4.9.

[tex]\frac{4.9x}{4.9} \frac{4.9}{4.9}[/tex]

Answer:

x = 4

y = 3.5

Step-by-step explanation:

The parallelogram given has opposite sides that are equal in length. Therefore, the diagonals bisect each other into two equal parts respectively.

Thus:

2y = 7

Divide both sides by 2

y = 7/2

y = 3.5

Also,

x + 6 = 10

Subtract 6 from each side

x = 10 - 6

x = 4

Using the formula for area of a circle: area = pi x r^2

You now have:

225pi ft^2 = pi x r^2

Divide both sides by pi:

225 = r^2

Take the square root of both sides:

r = 15

The radius is 15 feet.

The diameter is the radius x 2:

Diameter = 15 x 2 = 30 feet.

Answer: 30 feet.

Answer:

x = 43 degrees

Step-by-step explanation:

First, you have to see that there is a right angle of 90 degrees. Since that is there, you know that there is 90 degrees in the bottom and right side as well. So all you do in this question is do 90 - 47 to get your answer of 43 degrees.

Answer:

I may be wrong, but it should be around 37301.18 Canadian dollars

Step-by-step explanation:

The  Chevy Volt costs  in Canada is 37,888 Canadian Dollar

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit

1 United States Dollar = 1.28 Canadian Dollar

According to the question

Chevy Volt costs in the United States  =  $29,600

As, per  current marked value

1 United States Dollar = 1.28 Canadian Dollar

Cost in Canada =  29,600 *  1.28 Canadian Dollar

                         =   37,888 Canadian Dollar

Hence, the  Chevy Volt costs  in Canada is 37,888 Canadian Dollar
