WHATS THE ANGLE MEASUREMENTS ?? & TELL HOW YOU GOT IT !!

Dafna1 [17]

Answer:

...

Step-by-step explanation:

7x - 2 +5x - 10 +4x = 180

16x - 12 = 180

16x = 168

x = 10.5

now plug it in

7(10.5) - 2 = 71.5°

4(10.5) = 42°

5(10.5) -10 = 42.5°

Convert 83% into a decimal<br> can you guy help me to do that

PilotLPTM [1.2K]

To convert a percentage to decimal form, you need to divide the number in the percent by 100. In reality, that just looks like moving the decimal point to the left two places.

83% / 100 = 0.83

83% in decimal form is 0.83.
Hope that helped! =)

PLEASE HELP QUICK!! WILL OFFER 100 POINTS TO THE FIRST ONE THAT ANSWERS

Given

$x+1 = \sqrt{7x+15}$

We have to set the restraint

$x+1\geq 0 \iff x \geq -1$

because a square root is non-negative, and thus it can't equal a negative number. With this in mind, we can square both sides:

$(x+1)^2=7x+15 \iff x^2+2x+1=7x+15 \iff x^2-5x-14 = 0$

The solutions to this equation are 7 and -2. Recalling that we can only accept solutions greater than or equal to -1, 7 is a feasible solution, while -2 is extraneous.

Similarly, we have

$x-3 = \sqrt{x-1}+4 \iff x-7=\sqrt{x-1}$

So, we have to impose

$x-7\geq 0 \iff x \geq 7$

Squaring both sides, we have

$(x-7)^2=x-1 \iff x^2-14x+49=x-1 \iff x^2-15x+50 = 0$

The solutions to this equation are 5 and 10. Since we only accept solutions greater than or equal to 7, 10 is a feasible solution, while 5 is extraneous.

The distance between Dallas and Fort Worth on a map is 7.5 centimeters. The map uses a scale in which 1 centimeters represents 3

anyanavicka [17]

Hi There

To find the distance, you have to make them proportional to each other.

1 cent. / 30 kilo. = 7.5 cent. / x

Then you cross multiply.

30 x 7.5 = x

225 = x

The distance between the two cities is 225 kilometers.

Hope that helps:)
