I assume you mean the mixed number 1 + 7/9.

As an improper fraction, we have

1 7/9 = 1 + 7/9 = 9/9 + 7/9 = (9 + 7)/9 = 16/9

Then the square root of this is

√(1 7/9) = √(16/9) = √(4²/3²) = √((4/3)²) = 4/3

Determine whether abc ----> jgh is a reflection, translation, rotation, or glide reflection.

Usimov [2.4K]

From this picture you can calculate coordinates of triangles' vertices:
$A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)$ .

Since

$\frac{-9+8}{2} = \frac{-6+5}{2}= \frac{-3+2}{2}=- \frac{1}{2}$ $\frac{0+0}{2}= \frac{-4+4}{2} = \frac{0+0}{2} =0$

you can conclude that points A, B, C are rotated by $180^0$ about the point (-0.5,0) to form points J, G, H, respectively.

Answer: A is correct choice.

How do i solve -2y=8

Viefleur [7K]

If you're trying to solve for y
-2y = 8
Divide -2 to both sides
$\frac{-2y}{-2} = \frac{8}{-2}$
Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4

guajiro [1.7K]

Answer:

42 acres to 72 acres, there is an increase of 30 acres

percentage wise

72-42=30

30/72=.4166...

therefore there is also a 41.6% increase

Step-by-step explanation:

71.42 Percentage change:×100%

Now, the change is given from 42 acres to 72 acres, therefore

Change= 72-42=30

⇒Percentage change= ×100%

= 71.42

A baseball coach bought some bats and gloves for the school's baseball team.the bats cost $20 to $35,and gloves cost $30 to $60.

arlik [135]

Max cost of 15 bats = 15 x 35 = $535

Min cost of 15 bats = 15 x 20 = $300

Max cost of 12 gloves = 12 x 60 = $720

Mix cost of 12 gloves = 12 x 30 = $360

Min total cost = 360 + 300 = $660

Max total cost = 535 + 720 = $1255

The range is from $660 to $1255

=============> Answer (A) is out of the range
