3: Zero

Answer:

6

Step-by-step explanation:

AB+BC=AC

3x + 4x = 42

7x = 42

x = 42/7

x = 6

Answer:

a) language

b) 2/15

Step-by-step explanation:

For the first part, you can start by making the denominators same

you take the LCM of 3 and 5 which is 15

Language books are now 10/15 since you multiply the nominator and denominator by 5

While science books are 3/15

10/15 : 3/15 making it obvious that language books are more

if the remaining are math books then

total books - (language + science books) = math books

10/15 + 3/15 = 13/15 (non math books)

15/15 - 13/15 are math books making 2/15 of them math books

Answer:

99/100

Step-by-step explanation:

First of all recall that

[tex]a^n\cdot b^n =(ab)^n[/tex]

Now we we will try to apply that formula for [tex]a=99/100[/tex] and [tex]b=100/99[/tex].

First rewrite [tex](99/100)^{101}=(99/100)\times (99/100)^{100}[/tex]

Now

[tex](99/100)\times (99/100)^{100}\times (100/99)^{100}\\=(99/100)\times ((99/100)\times (100/99))^{100}\\=(99/100)\times 1^{100}\\=(99/100)\times 1\\=99/100[/tex]

Answer:

See below.

Step-by-step explanation:

Cos O is positive in the first and 4th quadrants and sin O is negative in the 3rd and 4th quadrants.

So the answer is Quadrant 4.

cos^2 O = 1 - sin^2 O

= 1 - (-3/5)^2

= 16/25

So  cos O  is +√(16/25)

= 4/5.

Step-by-step explanation:

Since b2 is certainly positive, that means a2 is certainly negative, which is impossible. √−1=i is an imaginary number, not lying anywhere on the real number line. Therefore as others have said, it is neither rational nor irrational in the usual senses of those words.

Answer:

No, you would get -1

Step-by-step explanation:

Square root of 1 is 1

If the negative was IN the square root, it would be imaginary.

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]  , [tex]a^{0}[/tex] = 1

5 (a)

[tex]7^{-6}[/tex] = [tex]\frac{1}{7^{6} }[/tex]

(b)

[tex]\frac{1}{10^{-3} }[/tex] = 10³

(6)

27[tex]x^{0}[/tex][tex]y^{-2}[/tex] ← substitute x = 4 , y = 3

= 27[tex]4^{0}[/tex][tex]3^{-2}[/tex]

= 27 × 1 × [tex]\frac{1}{3^{2} }[/tex]

= 27 × [tex]\frac{1}{9}[/tex]

= 3

Answer:

Step-by-step explanation:

1500 + (1500 : 100 × 4)

= 1500 + (15 × 4)

= 1500 + 60

= 1560

I'll do the first five problems to get you started.

===========================================================

Problem 1

Subtraction can be thought of as adding a negative.

So -3 - 6 is the same as -3 + (-6)

We can think of an example involving money

-3 means we're 3 dollars in debt. Then -6 means we go 6 dollars further into debt. Therefore, the total debt is -3 + (-6) = -9 so overall we're 9 dollars in debt.

===========================================================

Problem 2

When subtracting a negative, the two will cancel out to form a positive. This is because negatives are opposite in nature. Two opposites undo one another.

So with all that in mind, something like 10 - (-4) will become 10 + 4

===========================================================

Problem 3

It's the same idea as the previous problem, but we're dealing with different numbers of course.

===========================================================

Problem 4

We'll use the ideas mentioned in problem 1. There's not much further to explain here.

===========================================================

Problem 5

Refer back to either problem 2 or problem 3 for a similar example. The negatives will cancel to form a positive.

Answer:

y = x + 3

Answer:

  C.

Step-by-step explanation:

The transformation ...

  g(x) = f(ax)

represents a horizontal compression of the graph by a factor of 'a'. Here, the original function graph is compressed by a factor of 3 horizontally, so the curve will look a lot narrower.

The appropriate choice is C.

Answer:

356

Step-by-step explanation:

Next two terms = 11 + 3 = 14

14 + 3

The rule is that the number is increasing by 3 in each term.

n th term = 2 + (n - 1)3

119 term

2 + (119 - 1)3

2 + (118)3

2 + 354

Hey there!

Convert the fraction to decimals.

-3/5 = -0.6

-0.6 < -0.4

Hence, -3/5 is not equal to -0.4.

Answer = NO

Answer:

494,615

Step-by-step explanation:

Strategy 1.

Line up 5,819 on the top, and 85 on the bottom. Multiply 9 x 5, and if there are any carry-ons, put them above the top line of numbers. Once done with multiplying the top by 5, go under the line and write a 0. Then continue to multiple with 8, in the same way. Then add the top and bottom line (your answers), and you should get 494,615.

Strategy 2.

Use a calculator.

Answer:

0<r<4

Step-by-step explanation:

-8<8-4r<8

Subtract 8 from each side

-8-8<8-4r-8<8-8

-16<-4r<0

Divide by -4, remembering to flip the inequality

-16/-4>-4r/-4>0/-4

4>r>0

Rewriting

0<r<4

Angles DUT and VUD sum to VUT. We can create an equation to model this.

DUT + VUD = VUT

Now, let's plug our values into the equation.

24x + 5 + 46 = 35x - 4

Simplify the left side.

24x + 51 = 35x - 4

Subtract 24x from both sides and add 4 to both sides.

55 = 11x

Divide both sides by 11.

5 = x

Answer:

Tatal volume of buckets = 60 l

leakage = 0.5 l /h

So total time taken = 60/0.5

= 120 h

so number of days = 120/24 = 5days

Step-by-step explanation:

Given sides of the triangle:

We know that the perimeter of a triangle is the sum of all the sides of a triangle.

Perimeter of the triangle,

= 3x^2 + 8 + 2x^2 + x + x - 3

= 3x^2 + 2x^2 + x + x + 8 - 3

= 5x^2 + 2x + 5

Therefore, the perimeter of the triangle is 5x^2 + 2x + 5. Hence, the option A is the correct answer.

Jenn is the fastest swimmer.

Time and speed is inverse proportion. If speed is more, the time taken will be less. So, who takes less time will be the fastest swimmer

We can tell from the table that Jenn is the fastest swimmer. She has the lowest time and fastest speed
