If angle P is a right angle and angle P and Q from a linear pair, then angle Q is

anygoal [31]

< P is a right angle.....a right angle is 90 degrees.
< P and < Q form a linear pair....a linear pair, when added, = 180 degrees

so if < P is 90.....and when added to < Q = 180...
90 + Q = 180
Q = 180 - 90
Q = 90 <== so < Q is also a right angle...measures 90 degrees

The vertex form of the equation of a parabola is y=2(x+4)^2-7. What is the standard form of the equation.

Elan Coil [88]

Answer:

Step-by-step explanation:

To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:

y = 2[x^2 + 8x + 16 - 7], or

y = 2[x^2 + 8x + 9],

or y = 2x^2 + 16x + 18

None of the given possible answers match. The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).

Together, teammates Pedro and Ricky got 2682 base hits last season. Pedro had 282 more hits than Riley. How many hits did each p

pickupchik [31]

Pedro had 1482 hits and Riley had 1200 hits.

Step-by-step explanation:

Given,

Number of base hits = 2682

Let,

Number of Pedro's hits = x

Number of Riley's hits = y

According to given statement;

x+y=2682 Eqn 1

x = y+282 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+282)+y=2682\\y+282+y=2682\\2y=2682-282\\2y=2400$

Dividing both sides by 2

$\frac{2y}{2}=\frac{2400}{2}\\y=1200$

Putting y=1200 in Eqn 2

$x=1200+282\\x=1482$

Pedro had 1482 hits and Riley had 1200 hits.

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

fraction

<h3>let's solve:</h3>

to determine the length we have to divide 22 by 3

let's do:

$\frac{22}{3} \\ = 7 \frac{1}{3} \: feet \:$

let's the pieces be p

according to the question

$\sf 3p = 22 \\$
$\sf divide \: bot h \: sides \: by \: 3 : \\ \sf \frac{3p}{3} = \frac{22}{3} \\ p = 7\frac{1}{3}$
