Step-by-step explanation:

really ?

this is just using the calculator and see. there is no knowledge or anything else needed.

sqrt(17) = 4.123105626...

so, where does it go ? ... well ? ... right, third position.

sqrt(20) = 4.472135955...

soooo .... ? ... well ... ? ... right, first position.

sqrt(23) = 4.795831523...

aaaaand ... ? ... right, fourth position.

sqrt(19) = 4.358898944...

well, really, there is only one position left : second

Step-by-step explanation:

s = top speed

p = horsepower

s = 27.3 × p^(1/6)

the exponent 1/6 means the 6th root of p.

17.

s = 27.3 × 70^(1/6) = 27.3 × 2.030094899... =

= 55.42159075... knots

18.

50 = 27.3 × p^(1/6)

50⁶ = 27.3⁶ × p

p = 50⁶/27.3⁶ = (50/27.3)⁶ = (1.831501832...)⁶ =

= 37.74367151... horsepower

Answer:

1.50x>2.25x+9.00

Step-by-step explanation:

Because the 1.50 has to go their because 2.25 is greater than 1.50, the 9.00 is at the end because their is not a variable. How to know were theh variables go is the each.

She purchased a new lemon squeezer for $9.00.

The cost of the ingredients for each serving of lemonade is $1.50.

She will be selling each serving of lemonade for $2.25.

The inequality that represents the minimum number of servings of lemonade is 1.50x>2.25x+9.00.

We have given that,

Malika is making lemonade to sell at a school fundraiser.

The total cost is the addition of all the costs.

Malika must sell for the money from her sales to exceed the total cost of making the lemonade.

Because the 1.50 has to go there because 2.25 is greater than 1.50, the 9.00 is at the end because there is not a variable.

How to know where variables go is the each.

She purchased a new lemon squeezer for $9.00.

The cost of the ingredients for each serving of lemonade is $1.50.

She will be selling each serving of lemonade for $2.25.

Therefore we get the inequality that represents the minimum number of servings of lemonade is 1.50x>2.25x+9.00.

Answer:

the answer is -1

Step-by-step explanation:

simple:

7+(-5)

= +2  ( seven has the higher absolute value, so we go with positive)

+2 + (-3)

= -1 (we go with the negative this time because -3 has the higher absolute value)

Step-by-step explanation:

The values of n and p which makes the system of equations true are 10 and 20 respectively.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have system of equation:

p=2n  and

p−5=1.5n

Put p = 2n in the other equation.

2n - 5 = 1.5n

2n = 1.5n +5    (add 5 on both sides)

0.5n = 5           (subtract 1.5n on both sides)

n = 10              (divide by 0.5 on both sides)

Put n = 10 in the equation p = 2n

p = 2(10) = 20

Thus, the values of n and p which makes the system of equations true are 10 and 20 respectively.

Answer:

y ≈ 46.2

Step-by-step explanation:

using the law of sines , then

[tex]\frac{y}{sin85}[/tex] = [tex]\frac{31}{sin42}[/tex] ( cross- multiply )

y × sin42° = 31 × sin85° ( divide both sides by sin42° )

y = [tex]\frac{31sin85}{sin42}[/tex] ≈ 46.2 ( to the nearest tenth )

Using linear function concepts, we have that the interpretations are given as follows:

A linear function is modeled by:

y = mx + b

Step-by-step explanation:

Answer:

→ 50°

→ Acute triangle

Step-by-step explanation:

the measure of the third angle = 180 - (60 + 70) = 180 - 130 = 50°

definitions=======================================

Acute angle : it’s an angle that measures less than 90°.

Acute triangle: it’s a triangle with three acute angles.

………………………………………………………………………………………………

The measures of the angles in our triangle are respectively 60° , 70° , 50°

Thus ,it’s an acute triangle .

First plot the points that you are given. If a point is below the x-axis, then it is considered negative.

I hope this helps. I’m not sure what points you are given.

Answer:

x = 3

Step-by-step explanation:

8x + 4 = 28

subtract 4 from both sides

8x + 4 - 4 = 28 - 4

8x = 24

divided both sides by 8

8x / 8 = 24 / 8

x = 3
