Answer:

Step-by-step explanation:

The target area is shown in the attached picture.

We want to figure out probability of hitting red region.

The area of the figure is the area of the red square, which is 196.

Area of red region is area of whole square (196) minus area of blue square (64). So we have:

Area of red region = 196 - 64 = 132

Probability of hitting red region is 132 divided by total, which is 196.

$\frac{132}{196}=0.67$

Answer choice C is right.

Which of the following theorems verifies that ABC~WXY?

Bumek [7]

Answer:

The correct answer is option B. AA

Step-by-step explanation:

Given two triangle:

$\triangle ABC$ and $\triangle WXY$ .

The dimensions given in $\triangle ABC$ are:

$\angle A = 27^\circ\\\angle B = 90^\circ$

We know that the sum of three angles in a triangle is equal to $180^\circ$ .

$\angle A+\angle B+\angle C = 180^\circ\\\Rightarrow 27+90+\angle C=180^\circ\\\Rightarrow \angle C = 63^\circ$

The dimensions given in $\triangle WXY$ are:

$\angle Y = 63^\circ\\\angle X = 90^\circ$

We know that the sum of three angles in a triangle is equal to $180^\circ$ .

$\angle W+\angle X+\angle Y = 180^\circ\\\Rightarrow \angle W+90+63=180^\circ\\\Rightarrow \angle W = 27^\circ$

Now, if we compare the angles of the two triangles:

$\angle A = \angle W = 27^\circ\\\angle B = \angle X= 90^\circ\\\angle C = \angle Y= 63^\circ$

So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.

$\triangle ABC \sim \triangle WXY$ by AA theorem.

So, correct answer is option B. AA

The system of equations: 5x-4y=-3

Sophie [7]

Answer:

3)5x-4y=-3

6x+4y=14

Step-by-step explanation:

The system of equations is given

5x-4y=-3

3x+2y=7

Multiplying both sides of the lower equation by 2, we get

6x + 4y = 14

That means your answer 3)

PLZZZZZZZZZZZZZZZZ HELP ME!!! 1 1/8 to decimal show your work!!!

lions [1.4K]

Answer:

1.125

Step-by-step explanation:

1) First you have to turn it into an improper fraction

8*1 = 8. Add the numerator--> 8+1 = 9.

2) The improper fraction is 9/8

3) Divide 9 by 8

**Write this using long division

8 goes into 9 one time, so we will write one as our first digit

Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.

And this point we have 1.1 above

Carry down the 2 and the 0, 8 goes into 20 2 times so write 2

At this point we have 1.12

Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.

Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.
