Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

Hypotenuse ( h ) = 15
Perpendicular ( p ) = a
Base ( b ) = 9

$\underline{ \underline{ \text{To \: find}}} :$

Value of a

$\underline{ \underline{ \text{Solution}}} :$

$\underline{ \text{USE \: PYTHAGOREAN \: THEOREM}} :$

⤏ $\tt{ {p}^{2} = {h}^{2} - {b}^{2} }$

⤏ $\tt{ {a}^{2} = {15}^{2} - {9}^{2} }$

⤏ $\tt{ {a}^{2} = 225 - 81}$

⤏ $\tt{ {a}^{2} = 144}$

⤏ $\tt{a = \sqrt{144}}$

⤏ $\tt{a = \sqrt{ {(12)}^{2} } }$

⤏ $\tt{a = 12}$

$\red{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \tt{12 \: \text{units}}}}}}}$

Hope I helped ! ツ

Anna, Beth and Colleen are softball players. This season, Anne had 65 base hits in 160 at-bats. Beth batting average was 0.399,

zheka24 [161]

Answer:

Anne is the best hitter as she has the best hitting average of 0.406

Step-by-step explanation:

Anne hits 65 bases out of 160 at - bats.

Beth's betting average = 0.399

Collin's hit = 40%

Now, we need to convert all the three hitting rates into same parameters to compare them with each other.

Average hit rate of Anne = $\frac{\textrm{Total numberof base}}{\textrm{Total number of at - bats}}$

$= \frac{65}{160} = 0.406$

⇒The betting average of Anne = 0.406

Now, The hit - rate of Collin = 40%

Converting the percentage rate into decimal, we get the hit rate of Collin

= $\frac{40}{100} = 0.40$

Hence, we get that Hitting Average of :

<u>Anne = 0.406</u>, Beth = 0.3999 and Collin = 0.400

Hence, from the above data Anne is the best hitter as she has the best hitting average of 0.406.

Which graph shows the points (−112, 12) and (1.5, −0.5) plotted correctly? On a coordinate plane, a point is 0.5 units to the ri

chubhunter [2.5K]

Answer:

Graph 'B' represents the correct graph.

The correct graph is attached below.

Step-by-step explanation:

Let 'A' be the point:

$A\left(-1\frac{1}{2},\:\frac{1}{2}\right)$

Let 'B' be the point:

$B\:\left(1.5,\:-0.5\right)$

As point A(-1 1/2, 1/2) can be written as:

$A=\left(-\frac{3}{2},\:\frac{1}{2}\right)=\left(-1.5,\:0.5\right)$

so plotting the point $A=\left(-1.5,\:0.5\right)\:\:\:\:$ and $B\:\left(1.5,\:-0.5\right)$ on a $B\:\left(1.5,\:-0.5\right)$ .

As we know that the 2nd quadrant, in the upper left-hand corner, consists of negative values of x and positive values of y.

Thus, the point A(-1.5, 0.5) will be plotted in the 2nd quadrant at x = -1.5 and y=0.5

i.e. at x= -1.5, y = 0.5

As we know that the 4th quadrant, the lower left-hand corner, consists of positive values of x and negative values of y.

Point B(1.5, -0.5) will be plotted in the 4th quadrant at x = 1.5 and y = -0.5

i.e. at x= 1.5, y = -0.5

Thus, graph 'B' represents the correct graph.

The correct graph is attached below.
