Answer 1

Answer:

123°

Step-by-step explanation:

you're finding the measurement of angle xwz, so as you already know the measurement of angle wxy and ywz, you simply have to add the measurements together and you'll get the answer 123° ^^ I hope this helped :)

Answer 2

Answer:

123 degrees

Step-by-step explanation:

Angle XWZ is the combination of both XWY and YWZ. We're given both of the angle measurements, so the sum of both of the angles will give us the answer. 84 + 29 = 123.

Bran is driving at a constant speed shown in the graph. What is the constant of proportionality in this relationship?

Answers

The answer is 2.5m/s. On the graph you see 4 spaces to get to 100 so you know that it’s traveling by 25m per line (100/4). Since the slope lies on its first point at (25, 10), the slope measures 25/10. Divide the two to get your meters per second which ends up to be 2.5m/s.

Answers

Answer:

9[tex]\sqrt{2}[/tex] inches

or

12.728 inches

Step-by-step explanation:

Use Phytagorean Theorem

[tex]a^{2} +b^{2} =c^{2}[/tex]

Since both all sides of a square are equal, this means that [tex]a^{2}[/tex] and [tex]b^{2}[/tex] are equal.

So that leaves us with:

[tex]a^{2} +a^{2} = 18^{2}[/tex]

Simplify

[tex]2a^{2} = 324[/tex]

Divide both sides by 2

[tex]\frac{2a^{2} }{2} =\frac{324}{2}[/tex]

Simplify

[tex]a^{2} = 162[/tex]

Find the square root of both sides

[tex]\sqrt{a^{2} } =\sqrt{162}[/tex]

a = 9[tex]\sqrt{2}[/tex]

(or if you want the decimal, rounded to the 3rd decimal place: 12.728)

Jade buys a blouse and a skirt for 3/4 (fraction) of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt? Enter your answer in the box.

Answers

Answer:

$24

Step-by-step explanation:

Original price of blouse = $18

Discounted price of blouse = 3/4 x 18 = $13.50

Discounted blouse + discounted skirt = $31.50

⇒  13.50 + discounted skirt = 31.50

⇒  discounted skirt = 31.50 - 13.50 = 18

Let S be the original price of the skirt.

If the discounted skirt is 3/4 of it's original price, then

$18 = (3/4) S

S = 18 ÷ 3/4 = 24

Therefore, the original price of the skirt is $24

Subscript n Baseline C Subscript k Baseline = StartFraction n factorial Over (n minus k) factorial times k factorial EndFraction 0. 024 0. 031 0. 132 0. 309.

Answers

The probability that exactly 2 voters will be in favor of the ballot initiative is 0.309.

Given

Number of voters who support ballot initiative = 30 % = 0.30

Number of voters who does not support this initiative = 1 - 0.30 = 0.70

Number of voters selected for Surveying = 5

What is probability?

The probability of success and failure remain the same throughout the trials.

The probability that exactly 2 voters will be in favor of the ballot initiative is given by;

If P denotes Success and Q denotes failure;

[tex]\rm = ^{5}C_2 \times (0.3)^2 \times (0.70)^3\\\\= 10 \times 0.09 \times 0.343\\\\= 0.309[/tex]

Hence, the probability that exactly 2 voters will be in favor of the ballot initiative is 0.309.

Brandon has a jar of quarters and dimes with a total value of $10.05. The number of quarters is 3
less than twice the number of dimes. How many quarters and how many dimes does Brandon
have?

Answers

Answer:

Brandon has 18 Dimes and 33 Quarters  [Beware:  The problem does not state that Brandon owns the coins - he just has them.  Check your pockets]

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q).  I'll use pennies instead of dollars, so avoid the clutter of decimal points.

We are told that:

Q = 2D - 3  [The number of quarters is 3 less than twice the number of dimes.]

and

25Q + 10D = 1005   [total value of $10.05]

Substitute the value of Q in the first equation in the second, so that we have an equation with just one unknown, D.

25(2D-3) + 10D = 1005

50D - 75 + 10D = 1005

60D = 1080

D = 18

Q = 2D - 3

Q = 2(18) - 3

Q = 33

=============================

Check

25Q + 10D = 1005

25(33) + 10(18) = 1005  ?

825 + 180 = 1005  YES

----

Q = 2D - 3 ?

33 = 2(18) - 3    YES

L'area di un quadrato è di 50cm
quanto misura la diagonale?

Answers

Il metodo più utilizzato e conosciuto per calcolare l'area di un quadrato è molto semplice: consiste nell'elevare al quadrato la lunghezza di uno dei suoi lati. La formula matematica è {\displaystyle A=l^{2}}A=l^{{2}}. Talvolta, tuttavia, l'unica informazione che si ha a disposizione è la lunghezza della diagonale di un quadrato, cioè la retta che ne congiunge i due vertici opposti. Se hai già studiato i triangoli rettangoli, puoi imparare una nuova formula che consente di calcolare l'area di un quadrato conoscendo solamente la misura della sua diagonale.
