[tex]t \approx 4.501\,s[/tex]

Step-by-step explanation:

The second-grade equation must be rearragend into its standard form:

[tex]-16\cdot t^{2} + 70\cdot t + 9 = 0[/tex]

Roots can be found with the help of the General Equation for Second-Order Polynomial:

[tex]t = \frac{-70\pm \sqrt{70^{2}-4\cdot (-16)\cdot (9)}}{2\cdot (-16)}[/tex]

[tex]t = 2.188 \pm 2.313[/tex]

[tex]t_{1} \approx 4.501\,s[/tex]

[tex]t_{2} \approx -0.125\,s[/tex]

Only the first root offers a reasonable solution.

Step-by-step explanation:

I used google, and I wish there were some answer choices!! If there are, let me know!!

The temperature in the greenhouse before the heater stopped working was at least 71 degrees Fahrenheit, based on the information that the temperature dropped 6 degrees but remained at least 65 degrees.

As the temperature dropped 6 degrees and was still at least 65 degrees when the heater was fixed, we can set up a simple inequality to represent this situation:

Let T represent the temperature before the heater stopped working. After the heater stopped working and the temperature dropped by 6 degrees, the new temperature would be T - 6. According to the provided information, this new temperature was still at least 65 degrees, which gives us the inequality:

T − 6 ≥ 65

Adding 6 to both sides of the inequality, we find:

T ≥ 71

This means that the temperature in the greenhouse before the heater stopped working was at least 71 degrees.

The lowest temperature in January is -10°C.

Integers come in three types:

Given:

The lowest temperature in January was less than−6°.

as, we know in integers the smaller the number the grater its value.

such as -100 < (-1)

So, -6 > -10

and, -6 < 0

and, -6 < -5

and, -6 < -2.

Thus, the lowest temperature is -10°C.

Final answer:

The lowest temperature in January can be any temperature that is less than -6°.

Explanation:

The question asks for the lowest temperature in January, given that it is less than -6°. Since the question does not provide a specific range, any temperature that is less than -6° can be considered the lowest temperature in January. For example, -10°, -15°, or -20° can all qualify as the lowest temperature in January.

Answer: 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).

Step-by-step explanation:

This question is a system of equations. First, we will define our variables:

Let x= number of pints of the first fruit drink (60% pure fruit juice), and then y = the number of pints of the second fruit drink(85% pure fruit juice).

We know that there are 160 total pints of the mixture. Therefore,

x + y = 160 .......... equation i

We are also aware that 70% of those 160 pints will be pure fruit juice, and they will come from either x or y.

For x pints of the first juice, there is

0.6x of pure fruit juice and for y pints of first juice, there is 0.85y of pure fruit juice. Therefore, we will have:

0.6x + 0.85y = 160 × 0.7

0.6x + 0.85y = 112

Multiply through by 100 to remove decimal. This will be:

60x + 85y = 11200 ........... equation ii

Combine both equations

x + y = 160 .......... i

60x + 85y = 11200 ........ ii

Multiply equation i by 60

Multiply equation ii by 1

60x + 60y = 9600 ........ iii

60x + 85y = 11200 ......... iv

Subtract iv from iii

-25y = -1600

y = 1600/25

y = 64

Since x + y = 160

x = 160 - 64

x = 96

Therefore , we will need 96 pints of the first fruit drink (60% pure fruit juice) and 64 pints of the second fruit drink (85% pure fruit juice).

Step-by-step explanation:

We have been given that Fernando bought a jacket for $185 and sold it for 1 1/2 times what he paid.

Let us find selling price of jacket as:

[tex]\text{Selling price of Fernando's jacket}=\$185\times 1\frac{1}{2}[/tex]

[tex]\text{Selling price of Fernando's jacket}=\$185\times \frac{3}{2}[/tex]

[tex]\text{Selling price of Fernando's jacket}=\$277.5[/tex]

We have been given that Marisol spent 1/5 as much as Fernando on the same jacket.

[tex]\text{Cost of Marisol's jacket}=\$185\times \frac{1}{5}[/tex]

[tex]\text{Cost of Marisol's jacket}=\$37[/tex]

We are also told that Marisol sold the jacket for 1/2 as much as Fernando did.

[tex]\text{Selling price of Marisol's jacket}=\frac{\$277.5}{2}[/tex]

[tex]\text{Selling price of Marisol's jacket}=\$138.75[/tex]

The amount of money earned by Marisol would be selling price of jacket minus cost.

[tex]\text{Amount of money earned by Marisol}=\$138.75-\$37[/tex]

[tex]\text{Amount of money earned by Marisol}=\$101.75[/tex]

Therefore, Marisol made $101.75.

Answer:

area of a sector = 14.13 yards²

Step-by-step explanation:

XYZ is a sector of a circle. The radius YZ is 6 inches .The angle of the sector is given as 45°. The area of the sector can be solved as follows.

area of a sector = ∅/360 × πr²

where

r = radius

∅ = center angle

r = 6 inches

∅ = 45°

area of a sector = 45/360 × 3.14 × 6²

area of a sector = 45/360 × 3.14 × 36

area of a sector = 45/360 × 113.04

area of sector = 1/8 × 113.04

area of a sector = 14.13 yards²

We have been given that in an assembly line, 56 out of 60 randomly selected parts have no faults. We are asked to predict the number of parts that will have no faults in a similar batch of 12,000 parts.

We will use proportions to solve our given problem.

[tex]\frac{\text{Not faulty parts}}{\text{Total parts}}=\frac{56}{60}[/tex]

[tex]\frac{\text{Not faulty parts}}{12,000}=\frac{56}{60}[/tex]

[tex]\frac{\text{Not faulty parts}}{12,000}\times 12,000=\frac{56}{60}\times 12,000[/tex]

[tex]\text{Not faulty parts}=56\times 200[/tex]

[tex]\text{Not faulty parts}=11,200[/tex]

Therefore, approximately [tex]11,200[/tex] parts will have no faults in a similar batch of 12,000 parts.

Answer:

60 days, Friday

Step-by-step explanation:

This problem is solved using concept of LCM.

LCM is the least number which is the common multiple of given set of different number.

To find the LCM  we method of prime factors, the steps are given below

________________________________________________

Given

frequency of visiting swimming pool by Shwetha = once in 12 days

factors of 12 = 2 * 2 * 3

frequency of visiting swimming pool by Vinnie = once in 4 days

factors of 2 = 2 * 2

frequency of visiting swimming pool by Olga = once in 10 days

factors of 10 = 2 * 5

minimum no of days after which they will be visiting together will be least common multiple of number of days after which they visit swimming pool individually.

Selecting the prime numbers with their highest occurrence

we have 2, 2, 3 ,5

multiplying them together we have

2 * 2 * 3* 5 = 60

therefore 60 is the LCM of 12, 4, 10

it means that Shwetha, Vinnie and Olga will visit swimming pool together once in 60 days

It is given that they visited on Monday  and now they will visit after 60 days again.

since in one week there are seven days, every eighth day will be monday

so we divide 60 days by 7 to see how many cycles of monday has passed.

60/7 = 8  4/7

It suggest that 8 weeks has passed and they will meet on 4 days after Monday  which will be Friday.

Thus they will meet meet at the swimming pool again in 60 days.

It will be Friday.

Answer:

b.) [tex]50,48,14[/tex]

Step-by-step explanation:

To find if a set of lengths makes a right triangle, use the Pythagorean theorem:

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

If a and b squared equal c squared, then the set makes a right triangle. C (the hypotenuse) is the largest number of the set because the hypotenuse is always the largest side in a right triangle.

Use the options:

a.) insert values:

[tex]8^2+14^2=17^2\\64+196=289\\260\neq 289[/tex]

260 does not equal 289, so a is wrong.

b.) insert values:

[tex]14^2+48^2=50^2\\196+2304=2500\\2500=2500[/tex]

2,500 equals 2,500, so b is correct.

Finito.

Answer:

(3,0) and (0,6)

Step-by-step explanation:

(x,y) is the only way to make ordered pair.

The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).

Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.

So the answer is (3,0) and (0,6).
