1) 100N 2) 0.3m/s² 3) 1/2 kg

Step-by-step explanation:

1) F = ma

F = 50×2

F = 100N

2) F = ma

9000 = 30000×a

(9000÷30000) = a

a = 0.3m/s²

3) F = ma

1 = m×2

(1÷2) = m

Answer:

x=10.58

Step-by-step explanation:

To find the side length of a right triangle, you can use the Pythagorean theorem.

The Pythagorean theorem is [tex]a^2+b^2=c^2[/tex]

the c is the hypotenuse of the triangle, so 16.

the a and b are the other sides of the triangle, so x and 12.

Therefore, [tex]x^2+12^2=16^2[/tex]

       now you can solve the equation.

[tex]x^2+144=256[/tex]

      -144    -144

[tex]x^2=112[/tex]

now you have to square root both sides of the equation.

[tex]\sqrt{x^2} =\sqrt{112}[/tex]

x=10.58

What will be the new position of the given point (–2, –3) after reflection across the x-axis?
a) (2, 3)
b) (-3, -2)
c) (-2, 3)
d) (3, -2)

Answers

Answer:

(2,3)

Step-by-step explanation:

The new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

How to determine the new position?

The point is given as:

(-2,-3)

The rule of reflection across the x-axis is:

(x,y) -> (x,-y)

So, we have:

(-2,-3) -> (-2,3)

Hence, the new position of the point (–2, –3) after reflection across the x-axis is (-2,3)

Keith leaves a 15% for a dinner bill of $25. What amount of tip does Keith leave? $ What is the total bill? $

Answers

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Keith leaves a 15% for a dinner bill of $25. The amount of tip that Keith leaves will be calculated by multiplying 15% by $25. This will be:

= 15% × $25

= 15/100 × $25

= 0.15 × $25

= $3.75

Keith's total bill will be gotten by adding the dinner bill plus the tip together. This will be:

= $25 + $3.75

= $28.75

Round to the nearest hundredth:7.884

Answers

Answer:

7.88

Step-by-step explanation:

Hope this helps :D

When rounding to the nearest hundredth, the number 7.884 becomes 7.88.

To round 7.884 to the nearest hundredth, we look at the digit in the thousandth place, which is 8.

Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.

If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.

Since 8 is greater than or equal to 5, we round up the digit in the hundredth place.

Therefore, when rounding to the nearest hundredth, the number 7.884 becomes 7.88.

If Andre babysat 5 times and earned the same amount each time then it would be represented by the five rectangles with W on them.

If Andre got a $4 tip at the end of the month then it would be represented by the small 4 rectangle at the end.

If Andre made a total of 99 dollars then the large grouping 99 at the top would represent that.

If a family of 5 went to a concert in which all tickets costed the same then it would be represented by the five rectangles with W on them.

If they paid $4 for parking then it would be represented by the small 4 rectangle at the end.

If they spent a total of 99 dollars then the large grouping 99 at the top would represent that.

Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6?

O x= -1, x = 11

Ox=-1, x = -11

O x= 14 = -26

O x= 26, x=-14

Answers

Answer:

[tex]x = -1[/tex] or [tex]x = -11[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2|x+6| - 4[/tex]

Required

Find x when

[tex]f(x) = 6[/tex]

Substitute 6 for f(x)

[tex]6 = 2|x+6| - 4[/tex]

Add 4 to both sides

[tex]4+6 = 2|x+6| - 4+4[/tex]

[tex]10 = 2|x+6|[/tex]

Divide both sides by 2

[tex]5 = |x + 6|[/tex]

Rewrite as:

[tex]|x + 6| = 5[/tex]

This can be split to:

[tex]x + 6 = 5[/tex] or [tex]-(x + 6)=5[/tex]

Solve for x in both cases

[tex]x = 5 - 6[/tex] or [tex]x + 6 = -5[/tex]

[tex]x = -1[/tex] or [tex]x = -6 - 5[/tex]

[tex]x = -1[/tex] or [tex]x = -11[/tex]
