1. A ball is launched upward at 14 m/s from a platform that is 30 m high.
a. Find the maximum height the ball reaches.​

Answer:

100 $10 bills and

50 $20 bills

Step-by-step explanation:

Given

[tex]x = \$10[/tex]

[tex]y = \$20[/tex]

[tex]Bills = 150[/tex]

[tex]Value = \$2000[/tex]

Required

Determine the number of $10 and $20 bills

[tex]Bills = 150[/tex].

This implies that:

[tex]x + y = 150[/tex]

[tex]Value = \$2000[/tex]

This implies that:

[tex]10x + 20y = 2000[/tex]

So, the equations are:

[tex]x + y = 150[/tex]

[tex]10x + 20y = 2000[/tex]

Make x the subject in the first equation

[tex]x = 150 -y[/tex]

Substitute 150 - y for x in the second

[tex]10(150 - y) + 20y= 2000[/tex]

[tex]1500 - 10y + 20y= 2000[/tex]

[tex]1500 + 10y = 2000[/tex]

[tex]10y = 2000-1500[/tex]

[tex]10y = 500[/tex]

[tex]y =50[/tex]

Recall that:

[tex]x = 150 -y[/tex]

[tex]x = 150 -50[/tex]

[tex]x = 100[/tex]

x = 44

Answer:

angle 1 = angle 2

Step-by-step explanation:

1 and 2 are corresponding angles meaning if they are equal but on opposite sides. If you now for example angle 1 = 20 , 2= is also 20.   This is helpful to know if you want to solve for x on one of these angles

Answer:

D. 1/9

Step-by-step explanation:

The x-coordinate is -1/3

Answer:

The expression is not equivalent because you cannot combine 2 variables that are different from eachother.

Step-by-step explanation:

you are able to add 2+4 but because they have variables with them, x and y, you can not add them together.

Answer:

x = -33

Step-by-step explanation:

2/3(x+6) = -18

multiply (x+6) by 2/3

2/3x + 4 = -18

subtract 4 from both sides

2/3x + 4 - 4 = -18 - 4

2/3x = -22

multiply by 3/2

2/3 x 3/2 x = -22 x 3/2

x = -33

Step-by-step explanation:

so we basically  simplify the equation to the form, which is simple to understand

2/3(x+6)=-18 then Reorder the terms in parentheses

+( + 0.66666666666667x+4)=-18 after that

Remove unnecessary parentheses

+ 0.66666666666667x+4=-18 then We move all terms containing x to the left and all other terms to the right.

+ 0.66666666666667x=-18-4 so We simplify left and right side of the equation.

+ 0.66666666666667x=-22 We divide both sides of the equation by 0.66666666666667 to get x.

x=-33 get it?

answer:

y = 35

x = 35

explanation:

y and 35 are vertical angles therefore are equal.

x and 35 are alternate interior angles therefore are equal.

if correct, please mark the brainliest :)

Answer:

Both values equal 35 degrees

Step-by-step explanation:

This is because y and the angle that shows 35 degrees are vertical angles, meaning they have the same measurements. x and y are corresponding angles, which means they also have the same measurements.

Hope this helps :)

Answer:

The value of 3x is -9

Step-by-step explanation:

Given Equation

[tex]6(2x + 1) = - 36 - 2x[/tex]

Step 1

[tex]12x + 6 = - 36 - 2x[/tex]

Step 2

[tex]12x + 2x = - 36 - 6 \\ 14x= - 42 \\ x = \frac{ - 42}{14} \longrightarrow \frac{ - 3}{1} \\ x = - 3[/tex]

But we want to know what is the value of 3x.

Step 3

[tex]3x = 3( - 3) \\ 3x = - 9[/tex]

Hence, the value of 3x is -9

The answer is "[tex]\bold{\frac{1}{n}}[/tex]"

Step-by-step explanation:

Although n passwords were available and any time a wrong password is deactivated. Throughout the second try, if the secretary finds the right password, its input during the first attempt should be incorrect. Therefore, the likelihood is:

[tex]\to Pr= \frac{n-1}{n} \times \frac{1}{n-1} =\frac{1}{n}[/tex]

If n passwords were accessible and any time the wrong password is deactivated. Unless the delegate finds the right password on the three trials, the input should be incorrect during the first and second trials. Consequently, the likelihood is:

[tex]\to Pr= \frac{n-1}{n} \times \frac{n-2}{n-1} \times \frac{1}{n-2} =\frac{1}{n}[/tex]

Answer:

20,7,13. are the most correct for a triangular shape

Answer:

63° is the answer according to me

The value of measure of angle F is,

⇒ ∠ F = 63°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Triangle ABC and DEF are congruent.

Hence, Their corresponding angles are same.

So, We get;

⇒ ∠ A = ∠X

⇒ ∠B = ∠Y

⇒ ∠C = ∠Z

Here, ∠C = 63°

Hence, The value of measure of angle F is,

⇒ ∠ F = 63°

Thus, The value of measure of angle F is,

⇒ ∠ F = 63°

Step-by-step explanation:

Let's close the top part of the picture to make a parallelogram.

A parallelogram's four angles at each corner MUST be equal to 360 degrees.

Another property of a parallelogram is the opposite angles are congruent, meaning they're equal.

So, using these properties, we can now solve for a.
