<u>Answer:</u>

The value of x and y is 9 and 4 units

<u>Solution: </u>

We have,  

DH = x+3; HF= 3y and GH=3x-3; HE =5y + 4

For parallelogram, we know that,

DH=HF

So, (x+3)=3 y\Rightarrow x=(3 y-3)--------- (i)

Again, GH = HE

So, 3x-3 = 5y +4

\Rightarrow3 x=5 y+4+3

x = \frac{(5y+7)}{3} ………. (ii)

Now equating both (i) and (ii) we get,

\Rightarrow3 y-3=\frac{5 y+7}{3}

\Rightarrow3\times(3y-3) = 5y+7

\Rightarrow9y - 9 = 5y +7

\Rightarrow9y-5y=7+9

\Rightarrow4y = 16

\Rightarrow y = 4

So the value of x = 3\times4 -3 = 9

The value of x and y is 9 and 4  units

4. How fast was a driver going if the car left skid marks that were 32 feet long on dry concrete? (The coefficient of friction i
Monica [59]

Answer:

v_{o} \approx 31.247\,mph

Step-by-step explanation:

The deceleration experimented by the car is the product of kinetic coefficient of friction and gravitational constant:

a = \mu_{k}\cdot g

a = (1.02)\cdot \left(32.174\,\frac{ft}{s^{2}} \right)

a = 32.817\,\frac{ft}{s^{2}}

The initial speed is computed from the following kinematic expression:

v^{2} = v_{o}^{2} - 2\cdot a \cdot \Delta s

v_{o} = \sqrt{v^{2}+2\cdot a\cdot \Delta s}

v_{o} = \sqrt{\left(0\,\frac{ft}{s} \right)^{2}+2\cdot \left(32.817\,\frac{ft}{s^{2}} \right)\cdot (32\,ft)}

v_{o}\approx 45.829\,\frac{ft}{s}

v_{o} \approx 31.247\,mph

A bag contains 6 RED beads, 3 BLUE beads, and 11 GREEN beads. If a single bead is picked at random, what is the probability that
Anna11 [10]

Answer:

17/20

Step-by-step explanation:

Total no. of beads = 6 + 3 + 11 = 20

We need RED or GREEN bead .

So no. of beads needed = 6 + 11 = 17

So probability of getting GREEN or RED beads = 17/20

Write a proportion you could use to convert 2.5 gallons to quarts.
marusya05 [52]
We know there are 4 quarts in a gallon, so how many quarts in 2.5 gallons anyway?

\bf \begin{array}{ccll}&#10;quarts&gallons\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;4&1\\&#10;x&2.5&#10;\end{array}\implies \cfrac{4}{x}=\cfrac{1}{2.5}\implies \cfrac{4\cdot 2.5}{1}=x
