Now we plug in the numbers

(h, k) = center point (2, 5)

i need help can someone explain this simply

Answers

In order to do this, you have to use the Pythagorean Theorem which is a^2 +b^2=c^2 It does not matter in what order a and b are, but c is always the hypotenuse or the side across from the right angle. First, you substitute 24 in for a and 45 in for b so your equation so far would look like 24^2 + 45^2 = c^2 Then, you square 24 and 45 and get 576+2025=c^2 Then you add the two to get 2601=c^2 Finally, you would square root both sides and get 51=c So the width of the recycling bin is 51 inches long

Blank plus 1/2 equals 8/10​

Answers

3/10 plus 1/2 equals 8/10

Answer:

3/10 + 1/2 = 8/10

Step-by-step explanation:

? + 1/2 = 8/10

To figure this out, you would subtract 8/10 from 1/2. But first, you want to find a common denominator.

1/2 = 5/10

8/10 - 5/10 = 3/10

3/10 can not be reduced anymore so that would be your answer.

What is the volume of this birdfeeder? Round to the nearest tenth (if possible)

Answers

Answer:

14 in^3.

Step-by-step explanation:

The volume = volume of the bottom prism + volume of the top pyramid

= area of base * height of the prism + 1/3 * area of base * height of the pyramid

= 2 * 1.5 * 4 + 1/3 * (2*1.5) * 2

= 3*4 + 1/3 * 6

= 14 in^3.

where x = a  , then

[tex]x^{2}[/tex] =  [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)

[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)

A rectangle has dimensions 8 1/5 in by 13 in. A diagonal of the rectangle forms two matching right triangles. What is the area of one of the triangles.

The area of one of the triangle is ____ in.

Answers

Answer:

53.3 in^2

Step-by-step explanation:

Given data

Base B= 13in

Height H= 8 1/5 in= 41/5in

The expression for the area of a triangle is

Area= 1/2 Base * Height

Substitute

Area= 1/2* 13* 41/5

Area= 6.5*41/5

Area= 266.5/5

Area= 53.3 in^2

Hence the area is 53.3 in^2

angle 1= 55°
you can find this by doing 180-125=55
you get the 180 because angle 1 and 2 are on a straight line and there’s a line in between that creates the angles. a straight line is always 180°
anyways the answer is 55°

Roadsign cast of shadow that is 4 feet tall at the same time a 6 foot man standing next to the sign cast a shadow of those 2.4 feet long right and solve a proportion to find how tall the sign is

Answers

Answer:

10 feets

Step-by-step explanation:

Given that:

Road sign shadow (Rs) = 4 feets

Height of man (Hm) = 6

Man shadow (Ms) = 2.4 feets

Height of road sign (Hr) = x

Height of road sign / shadow of road sign = height of man / shadow of man

Hr/Rs = Hm / Ms

x / 4 = 6 / 2.4

Cross multiply :

4*6 = 2.4*x

24 = 2.4x

x = 24 / 2.4

x = 10 feets

Hence, height of road sign = 10 feets

The hydrogen ion concentration (h+) in a certain cleaning compound is (h+)=3.2x10^-11 use the formula ph=-log(h+) to find the pH of the clean compound the pH is approximately

Answers

Answer:

The [tex]pH[/tex] of the clean compound is approximately 10.495.

Step-by-step explanation:

If the cleaning ion concentration of the cleaning compound is [tex][H^{+}] = 3.2\times 10^{-11}[/tex], then the [tex]pH[/tex], no unit, of the compound is:

[tex]pH = -\log_{10} [H^{+}][/tex]  (1)

[tex]pH = -\log_{10} (3.2\times 10^{-11})[/tex]

[tex]pH = -\log_{10} 3.2 - \log_{10} (10^{-11})[/tex]

[tex]pH = -\log_{10} \frac{32}{10} +11[/tex]

[tex]pH = -\log_{10} 32 + \log_{10} 10 + 11[/tex]

[tex]pH = -\log_{10} 32 +12[/tex]

[tex]pH \approx 10.495[/tex]

The [tex]pH[/tex] of the clean compound is approximately 10.495.
