Find the area of the composite figure
Len [333]

Answer:

214in²

Step-by-step explanation:

A parallelogram/quadrilateral has four sides

So...

bh will be... 8 * 6

Because the two shapes are related i guess

and thats 48

Now for the area of a hexagon

The formula is...

3√3/2 t²

So plug the t(sides) in

You get

3√3/2 = 2.6

2.6(8)²

2.6 * 64 = 166.4

166.4 + 48 = 214.4

So, the answer is 214in² :)

What is the measure of ∠GJH?\<br><br> A. x = 19<br> B. x = 23<br> C. x = 48<br> D. x = 56
andrew11 [14]

Answer:

x = 19

Step-by-step explanation:

x + (x + 4) + (3x - 9) = 90°

Combine like terms

5x - 5 = 90

Add 5 on both sides

5x = 95°

Divide 5 on both sides

x = 19

How do you write algebraic expressions to model quantities
Marina CMI [18]
To write algebraic expressions to model quantities is you base the algebraic expressions or mathematical values declared in words by the manner of how the sentence illustrates the said problem. For example, one minus a number is the difference of zero shall be
1. 1 – n = 0.
Other same examples, John bought 25 apples while Julia bought only 15 from the market. If Niccole bought twice as much as Julia’s, how many was Niccole’s apples? <span><span>
1.      </span>You state the problem by the sequence of the said problem and understanding the possible structure.</span> <span><span>
2.      </span>Solution will be</span> Julia = 15 apples Niccole = 2Julia  
Hence, 2Julia = 2(15) = 30 apples.

A ball is launched straight up in the air from a height of 6 feet. Its velocity (feet/second) t seconds after launch is given by
german

Step-by-step explanation:

A ball is launched straight up in the air from a height of 6 feet. The velocity as a function of time t is given by :

f(t) = -32 t+285

Height of the ball is :

h(t)=\int\limits{f(t){\cdot} dt}\\\\h(t)=\int\limits{(-32t+285){\cdot} dt}\\\\h(t)=-16t^2+285t+C

C is constant. Here the ball is launched from a height of 6 feet. So,

h(t)=-16t^2+285t+6

At t = 2 s, h(t)=-16(2)^2+285(2)+6=512\ m

At t = 9 s, h(t)=-16(9)^2+285(9)+6=1275\ m

Between 2 s and 9 s, the ball's height changed is : 1275 - 512 = 763 m.
