Answer:

D. 10

Step-by-step explanation:

Since you divided by 2. You want to multiply to go back wards.

35×2=70

They already give you base(b=7) so to find the height you need to divide to go backwards since you multipled bh.

70÷7=10

now plug it in to see if the equation is right.

35= 1÷2 (7×10)

1) 462/11= 42

42x7=294

2) 9.38/7= $1.34

3) 6/11= 0.54545454545455

4) 1/4= 0.25

2/9= 0.22222222222

3/10= 0.30

2/1= 2.00

1/5= 0.20

least to greatest- 1/5, 2/9, 1/4, 3/10, 2/1

5) 9/15= 0.6 > 60%

to turn into a percent, move 2 decimal places!

6) 10/4= 2.5

2.5x18= 45

7) 2/3= 0.66666666666

0.66666666666x7= 4.66666666667

A sector with a central angle measure of 200 degrees has a radius of 9 cm. What is the area of the sector?

Sergio [31]

Answer:

$\boxed{Area\ of\ sector = 141.4\ cm^2}$

Step-by-step explanation:

Radius = r = 9 cm

Angle = θ = 200° = 3.5 radians

Now,

$Area \ of \ sector = \frac{1}{2} r^2 \theta$

Area = 1/2 (9)²(3.5)

Area = 1/2 (81)(3.5)

Area = 282.7 / 2

Area of sector = 141.4 cm²

Use the same coordinate plane to draw the graphs of the functions. Y=kx-2 if k=1, 0.4,-1

mario62 [17]

Graphs can be used to represent functions.

See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>

The function is given as: $\mathbf{y = kx - 2}$

When k = 1,

We have:

$\mathbf{y = 1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = x - 2}$

So, the equation is: $\mathbf{y = x - 2}$ when k = 1

When k = 0.4,

We have:

$\mathbf{y = 0.4\times x - 2}$ ----- substitution property of equations

$\mathbf{y = 0.4x - 2}$

So, the equation is: $\mathbf{y = 0.4x - 2}$ when k = 0.4

When k = -1,

We have:

$\mathbf{y = -1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = -x - 2}$

So, the equation is: $\mathbf{y = -x - 2}$ when k = -1

See attachment for the graphs of: $\mathbf{y = x - 2}$ , $\mathbf{y = 0.4x - 2}$ and $\mathbf{y = -x - 2}$
