Jose unlocks his cellphone by placing his right thumb on a square of 1 centimeter by 1 centimeter at the center of the screen. Upon recognizing his thumbprint, the square expands outward. The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds. What is the perimeter of the square after 1.5 seconds? 16.8 centimeters 19.2 centimeters 20.8 centimeters 29.2 centimeters

### Answers

Answer:

Step-by-step explanation:

We can solve this question using proportion

Perimeter of the square/Time is takes to unlock

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence, the perimeter of the square after 1.5 seconds is:.x = unknown

32/2.5 = x/1.5

Cross Multiply

2.5x = 32 × 1.5

x = 32 × 1.5/2.5

x = 19.2 centimeters

$24,995 and the contestant's guess is represented by g, what absolute value

inequality represents this situation?

### Answers

**Given :**

A contestant on a game show must guess the price of a new car. The contestant will win if his guess is within $1000 of the price of the car.

**To Find :**

If the price of the car is $24,995 and the contestant's guess is represented by g, what absolute value inequality represents this situation.

**Solution :**

Let, range in which participant guess would be considered correct is r.

So, r should be in range $( 24,995 ± 1000 ).

( 24,995 - 1000 ) ≤ r ≤ ( 24,995 + 1000 )

**23,995 ≤ r ≤ 25,995**

Therefore, the correct inequality is **23,995 ≤ r ≤ 25,995** .

Hence, this is the required solution.

A chemist has three different acid solutions. The first acid solution contains 15 % acid, the second contains 35 % and the third contains 65 % . He wants to use all three solutions to obtain a mixture of 72 liters containing 45 % acid, using 2 times as much of the 65 % solution as the 35 % solution. How many liters of each solution should be used?

### Answers

**Answer:**

18 liters 15% acid

18 liters 35% acid

36 liters 65% acid

**Step-by-step explanation:**

Let's say x is the volume of 15% acid, y is the volume of 35% acid, and z is the volume of 65% acid.

x + y + z = 72

z = 2y

The amounts of acid add up to the final amount.

0.15x + 0.35y + 0.65z = 0.45 (72)

Substitute the expression for z into both equations.

x + y + 2y = 72

0.15x + 0.35y + 0.65 (2y) = 0.45 (72)

Simplify:

x + 3y = 72

0.15x + 1.65y = 32.4

Solve for x in the first equation, then substitute into the second.

x = 72 − 3y

0.15 (72 − 3y) + 1.65y = 32.4

Solve for y.

10.8 − 0.45y + 1.65y = 32.4

1.2y = 21.6

y = 18

Now find x and z.

x = 72 − 3y = 18

z = 2y = 36

18 liters 15% **acid**, 18 liters 35% acid and 36 liters 65% acid should be **used**.

What is percentage?

**Percentage **is a measurement to find the value of a given **number **out of a hundred.

Let x is the **volume **of 15% acid, y is the volume of 35% acid, and z is the volume of 65% acid.

Given that, the total **mixture **is 72 liters,

Implies that,

x + y + z = 72

Also,65% **solution **is used two times as 35% solution is used.

z = 2y

The amounts of acid add up to the final amount.

0.15x + 0.35y + 0.65z = 0.45 (72)

Substitute the value of z here,

0.15x + 0.35y + 0.65 (2y) = 0.45 (72)

Simplify

x + 3y = 72

0.15x + 1.65y = 32.4

Solve for x in the first **equation**, then substitute into the second.

x = 72 − 3y

0.15 (72 − 3y) + 1.65y = 32.4

Solve for y.

10.8 − 0.45y + 1.65y = 32.4

1.2y = 21.6

y = 18

Now find x and z.

x = 72 − 3y = 18

z = 2y = 36

18 liters 15% acid, 18 liters 35% acid and 36 liters 65% acid should be used.

I'm writing a short story and I'm stuck on what should happen next. could you give me some ideas?

"M-Mr. Jacks!¨ Kate exclaimed, she turned her head to face him. His back was facing the sun and all she could see was the dark outline of his body. Kate stood up frantically, ¨You made it!¨ she was so excited. She noticed it was only him and wondered how everyone else was. “Did anyone else make it out?¨ she asked. He just stood there, no response. Instead, he walked closer, close enough for kate to actually see him. It wasn't Mr. Jacks. Standing there was a shadowy humanoid figure, it's presence gave her chills. Kate stepped back in fear. The shadow tilted it's head in an unnerving matter then lunged at her. ¨Ack!” Kate exclaimed, barely dodging it's attack. Although it ripped her shirt she was fine. W-what the heck, Kate thought. It lunged at her again, completely missing. Terrified, Kate started running, whatever this thing was she knew that she did not want to be caught up in it's attack. The shadow started chasing after her, it's form shifted, the legs got longer and the fingers were transformed into long dagger-like weapons. Oh no. oh no no no no. She thought and started running even faster Kate was running for a long time and was running out of breath, while the shadow was gaining on her. Well this is it i guess. She thought, breathing heavily. There's nothing i can do. Tears started forming in her eyes, even though this might be her last moments she had a smile on her face. At least this is better than starving to death in that bubble. Then all of a sudden Kate heard a gunshot. She looked behind her and this beautiful african american girl stood there, finger on the trigger. Another shot was fired and the shadow fell to the ground, shiveled up on the floor. The girl had short puffed hair, cold dark eyes, and had scars that covered her body. ¨Are you alright?¨ she called out. Kate fell to her knees and sighed in relief. Oh thank god. The girl walked over to her, ¨whats your name hon?¨ she asked. Kate looked up and replied, ¨My names kate and do you mean if i'm physically or mentally alright?¨ Which made the girl chuckle. ¨you seem fine to me¨ she said. ¨The names Alyiah.¨

Setup a rational equation and solve it from the word problem. Mr. Solberg can ride his scooter 3 miles against the wind in the same time it takes him to scooter 4 miles with the wind. If the speed of the wind is 5 mile per hour, how fast does Mr. Solberg scooter when there is no wind?

### Answers

**Answer:**

The speed of Mr Solberg's scooter when there is no wind is 35 miles per hour

**Step-by-step explanation:**

The given parameters are;

The time Mr. Solberg rides his scooter and cover 3 miles against the wind = The time Mr. Solberg rides his scooter and cover 4 miles with the wind

The speed of the wind = 5 miles per hour

Let v, represent the speed of Mr Solberg's scooter when there is no wind, we have;

Time = Distance/Speed

Mr Solberg's speed against the wind = v - 5

Mr Solberg's speed with the wind = v + 5

The distance covered at a given time, while riding against the wind = 3 miles

The distance covered at the same time, while riding with the wind = 4 miles

The time in both instances are therefore 3/(v - 5) = 4/(v + 5)

From which we have;

3 × (v + 5) = 4 × (v - 5)

3·v + 15 = 4·v - 20

20 + 15 = 4·v - 3·v

4·v - 3·v = 20 + 15

v = 35

The speed of Mr Solberg's scooter when there is no wind = v = 35 miles per hour.
