Answer:

42 square units

Step-by-step explanation:

Hello There!

The area of a trapezoid can be found using this formula

a =  \frac{a + b}{2} h

where a and b are bases and h is height

if you look at the graph we can see that the lines are counting by 2 units

knowing this we want to find the dimensions

the shown trapezoid has the following dimensions

a =2*2 or 4

b=5*2 or 10

h=3*2 or 6

having found this information we then plug it into the formula

a =  \frac{4+ 10}{2} 6 \\ 4 + 10 = 14 \\  \frac{14}{2}  = 7 \\ 7 \times 6 = 42

so we can conclude that the area of the trapezoid is 42 square units

Translate the phrase into an algebraic expression.
adell [148]

Answer:

8 + \frac{5}{w}

Step-by-step explanation:

From the phrase, the <em>answer</em> is smaller(less) by 8  when compared(equal (=)) to quotient of 5 and w ...

So:

Answer - 8 = quotient of 5 and w

Here, quotient is the whole number from a <em>division</em>. The division here is \frac{5}{w}

Therefore,

Answer - 8 = \frac{5}{w}

Answer = 8 + \frac{5}{w}

Hence the phrase into algebraic expression is 8 + \frac{5}{w}

Find the equation of a line that is parallel to y = 2x + 3 and passes through (-1, -1).
drek231 [11]

Answer:

  y = 2x +1

Step-by-step explanation:

The given line is in "slope-intercept" form, where the slope is the coefficient of x, 2, and the intercept is the added constant, 3. The parallel line will have the same slope, but its constant will be different. We can find the constant by putting the given point into an equation with the constant as the unknown:

  y = 2x + b

  -1 = 2(-1) +b . . . substitute for x and y

 2 -1 = b . . . . . . add 2

  1 = b

So the equation for the parallel line is ...

  y = 2x + 1

A cylinder has a radius of 3.2 meters its volume is 190 Cubic meters find its height to the nearest 10th of a meter
Stels [109]

Answer:

volume = pi r^2 h

or, 190 = pi (3.2)^2 h

or, 190/10.24 = pi h

or, 18.56 = 22/7 h

or, 18.56×7/22 = h

thus , h = 5.9037

In abc above,what is the length of ad​
Nezavi [6.7K]

Answer:

B

Step-by-step explanation:

First calculate BD using sine ratio in Δ BCD and the exact value

sin60° = \frac{\sqrt{3} }{2}, thus

sin60° = \frac{opposite}{hypotenuse} = \frac{BD}{BC} = \frac{BD}{12} = \frac{\sqrt{3} }{2} ( cross- multiply )

2BD = 12\sqrt{3} ( divide both sides by 2 )

BD = 6\sqrt{3}

-----------------------------------------------------------

Calculate AD using the tangent ratio in Δ ABD and the exact value

tan30° = \frac{1}{\sqrt{3} } , thus

tan30° = \frac{opposite}{adjacent} = \frac{AD}{BD} = \frac{AD}{6\sqrt{3} } = \frac{1}{\sqrt{3} } ( cross- multiply )

\sqrt{3} AD = 6\sqrt{3} ( divide both sides by \sqrt{3} )

AD = 6 → B
