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.

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

Answer:

b. (x , y) -> (-x , y)

Step-by-step explanation:

Reflection over y axis

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

Step-by-step explanation:

Just minus the half pints

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.

Answer:

144

Step-by-step explanation:

9*3=27

27*4=108

6^2=36

108+36=144

Answer:

[tex]\Large \boxed{\sf 144 \ ft^2}[/tex]

Step-by-step explanation:

Find the area of the 4 triangles and 1 square and add them.

Area of triangle = base × height × 0.5

Area of square = s²

[tex](9 \times 6 \times 0.5\times 4)+(6^2)=144[/tex]

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.

$52.324

Step-by-step explanation:

Answer:

Step-by-step explanation:

it is hard to know exactly by eye balling the graph  I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it

the dots on the line are at (-2, -6) and (2, 3)  so we can find the slope m

in the y = mx + b line equation   b is the y intercept

m = Δy/Δx     =  (y1 - y2) / (x1 - x2)

                     =  (-6 - -3) /  (-2 - 2)

                     =     -3 / -4

                 m = 3/4

       y = 3x/4  +  y intercept     which i can't dissern (read directly from the

                                                  graph, but we believe y = 0   when x is six

       0 = 3(6)/4  + y intercept

       -18/4 = 18/4 -18/4  + y intercept

        -9/2 = y intercept

        -4.5 = y intercept

   y = 3x/4 - 9/2          i think exact number means NO FRACTIONS but that is whole number so let me gaggle it  What are exact numbers?  Gaggle indicates exact numbers are integers   example  3 ft in a yard 12 eggs in a dozen

    y = 3x/4 - 9/2               multiple both sides by 4

   4y = 3x  - 36/2

   4y = 3x - 18    <------------------  FINAL ANSWER

have a good day!

Answer:

Step-by-step explanation:

you can use the side angle side formula  ( a form of Law of Cosines)

a^2 = b^2 + c^2 − 2bc cos(A)

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)

[tex]x^{2}[/tex] = 25 + 9 -8.7711511

x = 5.0228 cm

Answer:

[tex](x-2)^2+(y-5)^2=9^2[/tex]

Step-by-step explanation:

We use the equation

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Now we plug in the numbers

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

This would equal

[tex](x-2)^2+(y-5)^2=9^2[/tex]

Answer: jimmy needs a new job

Step-by-step explanation:

Answer: 1. 34 degrees+34 degrees=68 180-68=112 so x=112 degrees

2. 84+22=106 180-106=74 so x=74 degrees

3. 126+20=146 180-146=34 so x=34 degrees

4. both angles on both sides are 40 so 40+40=80 180-80=100 so x=100 degrees
