Answer:

31.25 s

Step-by-step explanation:

We'll begin by calculating the speed of Finn.

NOTE: Finn is swimming at a constant speed. Hence we shall use any of the data given in the question above to determine the speed of Finn. This is illustrated below:

Time = 7.25 s

Distance = 11.6 m

Speed =?

Speed = distance / time

Speed = 11.6 / 7.25

Speed = 1.6 m/s

Therefore, the speed of Finn is 1.6 m/s

Finally, we shall determine the time taken for Finn to swim 50 m. This can be obtained as follow:

Speed = 1.6 m/s

Distance = 50 m

Time =?

Speed = distance / time

1.6 = 50 / time

Cross multiply

1.6 × time = 50

Divide both side by 1.6

Time = 50 / 1.6

Time = 31.25 s

Therefore, the time taken for Finn to swim 50 m is 31.25 s.

Answer:

D) {11,-4,-29}

Step-by-step explanation:

rewrite the equation as y= -5x+1 and plug in -2,1 and 6 to get y

-5*-2+1=11

-5*1+1=-4

-5*6+1=-29

Answer:

x = 60

Step-by-step explanation:

The two angles shown here are known as corresponding angles. This means they both equal the same amount of degrees. Knowing this, we can set up an equation:

2x + 15 = 135

2x = 120

x = 60

Therefore, x = 60

You can check your answer by substituting the answer for x:

2(60) + 15 = 135

120 + 15 = 135

135 = 135

Answer:

whatever is higher than 1.5 is higher than r

Step-by-step explanation:

-1.5 ≤ -r

-1.5/-1 ≤ -r/-1

1.5 ≥ r

1.5 is equal to or bigger than r

Step-by-step explanation:

The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

Given the octagon with a perimeter of 48 cm

Let's say the length of each side is a

Perimeter = 8a

8a = 48

a = 6cm

Now,

The area of the triangle is given by

A = 1/2  × Base × Height

A = 1/2  × 6 × h

A = 3h

Now

A = 3h and the area is 21.7 cm²

So,

h = 21.7/3 = 7.23 cm

Hence "The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm".

We are to simplify the expression given

The simplified form of the expression is option B. 67/10x + 9

Given:

= 3(7/5x + 4) - 2(3/2 - 5/4x)

= [tex] \frac{21}{5} x + 12 - \frac{6}{2} - \frac{10}{4} x[/tex]

= 21/5x + 12 - 6/2 + 10/4x

collect like terms

= 21/5x + 10/4x + 12 - 6/2

= (84x+50x)/20 + (24-6)/2

= 134/20x + 18/2

7.2 x 10 CUBED

Step-by-step explanation:

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 7,200

New Number: 7.200

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 7 . 2 0 0

Decimal Count:   1 2 3

There are 3 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 7.2 (Please notice any zeroes on the end have been removed)

b = 3

Answer:

[tex]H=210.25\ \text{units}[/tex]

Step-by-step explanation:

Given that,

[tex]H = -16t^2 + 84t + 100[/tex] ...(1)

We need to find the maximum height

For maximum height, put dH/dt = 0

[tex]\dfrac{d(-16t^2 + 84t + 100)}{dt}=0\\\\-32t+84=0\\\\t=\dfrac{84}{32}\\\\t=2.625\ s[/tex]

Put t = 2.625 in equation (1)

[tex]H = -16(2.625)^2 + 84(2.625) + 100\\\\=210.25\ \text{units}[/tex]

Hence, the maximum height [tex]=210.25\ \text{units}[/tex]

Answer: Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.

You need to end up a mixture that is 60% antifreeze.

You have 90 gallons of 25% antifreeze, which means it has .25*90 = 22.5 gallons of pure antifreeze mixed with a solvent (probably water).

.

You will add 'x' gallons of 70% antifreeze to make the 60% mixture.

So, at the conclusion, you will have (90+x) gallons  60% 'pure' antifreeze. That can be shown with the equation:

.

.25*90 + .7*x = .6*(90+x)

.

Multiply by 100 to eliminate fractions.

.

25*90 + 70x = 60(90 +x)

.

2250 + 70x = 5400 + 60x

.

10x = 5400 -2250

.

10x = 3150

.

x = 315 gallons of 70% antifreeze.

.

How much will you end up having on hand?

90 + 315 = 405 gallons

.

If it is 60% antifreeze, how much 'pure' antifreeze will be in the mixture?

.6*405 = 243

.

In the original 90 gallons, you have 22.5 gallons of pure antifreeze.

In the additional 315 gallons, you have .7*315 = 220.5 gallons.

22.5+220.5 = 243 gallons

Step-by-step explanation:

Hope this helps,

Have a great day

The relationship between each proportion of antifreeze can be used to form an equation.

The number of 90% antifreeze that must be added is 490 gallons.

The question is incomplete. So, I will use the following details to answer the question

[tex]Av ai la bl e = 70[/tex] gallons of 10% antifreeze

[tex]x \to[/tex] gallons of 90% antifreeze

[tex]Total = x + 70[/tex] --- after mixing the solution; to get a 80% solution

The equation is then represented as:

[tex]70 \times 10\% + x \times 90\% = (x + 70) \times 80\%[/tex]

[tex]7 + 0.9x = 0.8x + 56[/tex]

Collect like terms

[tex]0.9x - 0.8x = 56 - 7[/tex]

[tex]0.1x = 49[/tex]

Divide by 0.1

[tex]x = \frac{49}{0.1}[/tex]

[tex]x = 490[/tex]

Hence, 490 gallons of 90% antifreeze must be added.
