Which value if any pls help

Answer:

Look at the work under "Step-by-step explanation"

Step-by-step explanation:

- 2y = - 3

[tex]y = \frac{ - 3}{ - 2} [/tex]

[tex]y = \frac{3}{2} [/tex]

- 2y = - 4

y = 2

- 2y = - 6

y = 3

- 21 +2y = - 10

2y = 11

[tex]y = \frac{11}{2} [/tex]

- 14 + 2y = - 10

2y = 4

y = 2

2y = - 10

y = - 5

Answer:

0.4 cups per cup of broth

Step-by-step explanation:

14 cups of water/35 cups of broth

This is the same as 14 divided by 35

14 divided by 35 is 0.4

Answer:

sailors used pulleys to help raise or lower sails, and to help pull heavy objects like whale boats or cargo onto ships. Today, the U.S. Navy still uses pulleys to pull heavy objects on board, usually with the help of a crane.

Answer:

Each Shirt would be 5.50$

Step-by-step explanation:

Answer:

The value of y is directly proportional to the value of x. When x = 4.25, the value of y is 2. What is the value of x when y = 8?

Step-by-step explanation:

Answer:

x = 17 when y = 8

Step-by-step explanation:

Considering the value of y,

→ 8 ÷ 2

→ 8/2 = 4

Now the value of x will be,

→ x = 4.25 × 4

→ [ x = 17 ]

Hence, the value of x is 17.

Answer:

√9 = ±3

Step-by-step explanation:

... Because 3 × 3 = 9 and (-3) × (-3) = 9

However, it is agreed universally that we take the so-called “positive square root”. That is, we accept that the only answer is 3. In contrast, when we have (x^2) =9, where x is a variable, we don't know whether x is positive or negative so we cannot rule out the possibility that x is negative.

Square root means a number that produces a specified quantity when multiplied by itself.

Answer:

± 3

Step-by-step explanation:

[tex]\sqrt{9}[/tex] = ± 3

That is + 3 or - 3

Since 3 × 3 = 9 and - 3 × - 3 = 9

Answer:

True is the most reasonable than False.

Step-by-step explanation:

If we go by "logic", we know that radius and anything that tells you how long, how far, how tall, etc; the value must always be positive.

The area of circle is expressed as:

[tex] \displaystyle \large{A = \pi {r}^{2} }[/tex]

Where r = radius

Since we know that radius cannot be negative going with logic and real basic geometry, the only radius that satisfies A = 9π is r = 3.

[tex] \displaystyle \large{A = \pi {3}^{2} } \\ \displaystyle \large{A = 9\pi }[/tex]

Now if we do not go by logic of real basic geometry, such as length being negative and all.

Since A = 9π, substitute A = 9π in.

[tex] \displaystyle \large{9\pi = \pi {r}^{2} }[/tex]

Divide both sides by π.

[tex] \displaystyle \large{ \frac{9\pi}{\pi} = \frac{\pi {r}^{2} }{\pi} } \\ \displaystyle \large{ 9 = {r}^{2} }[/tex]

Square both sides, adding plus-minus, apply QE.

[tex] \displaystyle \large{ \pm \sqrt{9} = \sqrt{ {r}^{2} } } \\ \displaystyle \large{ \pm 3 = r}[/tex]

So r = ±3 or radius = +3 and -3

So r can be both 3 or -3 if we do not follow logic itself.

However, the answer should be true instead of false as radius being only positive sounds more logical and reasonable rather than radius being negative.

Answer:

For each part, find how many numbers have the stated characteristic, then divide by 21.

e.g. multiples of 5:

these would be 10, 15, 20, 25, and 30

so prob (a multiple of 5 ) = 5/21

Do the others the same way

Answer:

50%

Step-by-step explanation:

% of 70,000 = 35,000

35,000/70,000 = 0.5

0.5*100 = 50

50%

Step-by-step explanation:

given :

A=5x - 10

B = 3x

C= 2x - 10

solution:

A+B+C = 180°

5x - 10 + 3x+ 2x - 10 = 180

10x -20 = 180

10x = 200

x = 20

A = 5(20)-10 = 100-10 = 90°

B = 3x = 3(20) = 60°

C = 2x-10 =2(20)-10 =40-10 = 30°

this is the right triangle and scalene triangle

Answer:

a = n/5 + 3h^2

step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.  

a = n/5 + 3h^2

Answer:

n+15 to the power of 2=a

Step-by-step explanation:

1.multiply 5 by and and -3h to the power of 2

2. subtract 15h to the power of 2 from both sides

3. divide by 5 on each side

Answer:

Step-by-step explanation:

The diagonal is the hypotenuse of the triangle with sides of 20.8 cm and 30.6 cm.

Find the length of the diagonal using Pythagorean:

Convert the length to inches:

Answer:

37 cm = 14.57 in

Step-by-step explanation:

A rectangle is a 4-sided shape with 2 pairs of congruent, parallel sides (width and length).

All interior angles of a rectangle are 90°.

The diagonal of a rectangle forms 2 congruent right triangles.  

Given:

Pythagoras Theorem

  [tex]a^2+b^2=c^2[/tex]

where:

Therefore:

Substitute the given values into the formula and solve for c:

[tex]\implies 20.8^2+30.6^=c^2[/tex]

[tex]\implies c^2=1369[/tex]

[tex]\implies c=\sqrt{1369}[/tex]

[tex]\implies c=37\:\:\sf cm[/tex]

Therefore, the length of the diagonal of the rectangle is 37 cm.

Conversion

1 inch ≈ 2.54 cm

To convert the measure of the diagonal to inches, divide 37 cm by 2.54:

[tex]\implies \dfrac{37}{2.54}=14.57 \sf \:in\:\:(2 \: d.p.)[/tex]

16+24=-4(9x-10)

Use the Distributive property first:

16+24=-36x+40

Make sure that x's and other variables are on the left side of the equation. Remember to use the opposite operation!

36x-40=-16-24

Now, make sure all the numbers are on the right side of the equation:

36x=40-16-24

36x=0

x=0

All the best!

Answer:

B. y – 9 = 3(x – 3); 36 cm

Step-by-step explanation:

Answer:

The equation which represents the given data is and  the height of the plant at 12 months is 36 cm.

Step-by-step explanation:

Given :

Time (months)(x): 3, 5, 7, 9.

Plant height (cm)(y), 9, 15, 21, 27.

Solution:

We will use two point slope form to find the equation which represents the given situation.

Formula:  

Substitute the values in the given formula.

Now we are supposed to find the height after 12 months.

So, the equation which represents the given data is and  the height of the plant at 12 months is 36 cm.

Thus Option B is correct.
