Answer:

32%

Step-by-step explanation:

The slope of the road is measured as

slope = \frac{rise}{run} = \frac{16}{50}

To express as a percentage multiply the fraction y 100% , that is

slope = \frac{16}{50} × 100% = 16 × 2 = 32%

Someone, please help me lol I'm small brain

Answer:

Measure of EF: 1.98

Measure of AB: 6.16

Measure of HI: 12.2

Step-by-step explanation:

Trick I learned that's very helpful when solving these problems: SOH (Sine, Opposite, Hypotenuse)- CAH (Cosine, Adjacent, Hypotenuse)- TOA (Tangent, Opposite, Adjacent)

MEASURE OF EF

you're starting with angle D which is 26 degrees. You have the measure of the Hypotenuse (DF) and you're trying to find the measure of EF (the segment opposite the angle) so you would use Sine

to do the equation, i'm going to use x in place of EF. 0.44 = sin(26)

Formula: sin(angle) = (opposite)/(hypotenuse)

Equation:

0.44 = x/4.5       <----------- multiply by 4.5 to get x by itself

4.5*0.44 = x       <---------- 4.5 times 0.44

1.98= x       <----------------answer

MEASURE OF AB

trying to find hypotenuse and you already have the adjacent angle so you would use cosine. Using y in place of AB. 0.616 = sin(52)

cos(angle) = (adjacent)/(hypotenuse)

cos(52) = 10/y      <------ divide by y

y*0.616 = 10       <------------ divide by 0.616

y = 10/0.616    <----------- next you'll divide 10 by 0.616

y = 6.16    <-----------answer

MEASURE OF HI

trying to find adjacent, already have opposite so you would use tangent. tan(42) = 0.90. using z in place of HI

tan(angle) = (opposite)/(adjacent)

tan(42) = 11/z   <------------ multiply z on both sides

z*0.90 = 11  <--------- divide by 0.90 to get z by itself

z = 11/0.90    <-------- divide 11 by 0.90

z = 12.2

Simplify the algebraic expression: x(x + 3) + x(2x - 4) + 6
marusya05 [52]

Step-by-step explanation:

x(x + 3) + x(2x - 4) + 6

First, let's distribute the x variable to each term in the first parenthesis:

x^{2} + 3x + x(2x - 4) + 6

Next, let's distribute the x variable to each term in the second parenthesis:

x^{2} + 3x + 2x^{2} - 4x + 6

Next, let's group like terms together:

(x^{2} + 2x^{2}) + (3x - 4x) + (6)

Finally, let's add or subtract like terms to get the result:

3x^{2} - x + 6
