answer is a

Step-by-step explanation:

Answer:

16. r = 20, t = 48

17. a = 104, b = 175

19. 144/252, 20/35

20. 14/21, 18/27

21. 16/48, 12/36

22. 219 grams

23. 5 milligrams

Step-by-step explanation:

Answer:

16. r = 20

     t = 48

17. a = 104

    b = 175

19. [tex]\frac{144}{20} =\frac{252}{35}[/tex]

     7.2 = 7.2

20. [tex]\frac{27}{18}= \frac{21}{14}[/tex]

     1.5 = 1.5

21. [tex]\frac{48}{16} =\frac{36}{12}[/tex]

     3 = 3

22. [tex]\frac{8}{3} :\frac{584}{y}[/tex]

     219 grams of peanuts

23. [tex]\frac{y}{2}: \frac{200}{80}[/tex]

     50 milligrams of medication

Step-by-step explanation:

16. [tex]\frac{r}{32} =\frac{5}{8} =\frac{30}{t}[/tex]

8 · 4 = 32

5 · 4 = 20

r = 20

5 · 6 = 30

8 · 6 = 48

t = 48

17. [tex]\frac{52}{a} =\frac{10}{20} =\frac{b}{350}[/tex]

Here is a different method.

[tex]\frac{10}{20} =\frac{1}{2}[/tex]

52 · 2 = 104

a = 104

350 ÷ 2 = 175

b = 175

22.

[tex]\frac{8}{3} :\frac{584}{y}[/tex]

8 · y = 3 · 584

8y = 1752

8y ÷ 8 = 1752 ÷ 8

y = 219

23.

[tex]\frac{y}{2}: \frac{200}{80}[/tex]

y · 80 = 200 · 20

80y = 4000

80y ÷ 80 = 4000 ÷ 80

y = 50

(a-b)(a+b) is the answer

Answer:

B,48.2

Step-by-step explanation:

To solve this we need to use SOH, CAH, TOA

we have the adjacent and hypotonouse so it's easiest to use CAH

let theta (angle) = x

cos(x)=4/6

to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)

x=48.1896851

which rounds to 48.2

Answer:

2/6 so the last box

Step-by-step explanation:

Answer:

The last box

Step-by-step explanation:

Answer:

Yes they are wrong, rational & irrational ones down below.

Step-by-step explanation:

So, lets start this by asking, what is a rational and irrational number?

Rational numbers are literally any numbers that arent pi, e, or other symbols, as well as square roots.

Irrational numbers are exactly the opposite, being the numbers that are symbols, including square roots.

Note that the symbols listed above such as pi are values that are neverending.

Now, using what we know of rational and irrational numbers, let see which answers are rational and which are not.

So, we start off with:

-13/3

I do not see a square root.

I do not see a symbol such as pi either.

It is not a ever going number.(number that continues infinitly)

So -13/3 is a rational number.

Next we have [tex]\sqrt{37}[/tex]

immediatly we tell it has a square root.

So [tex]\sqrt{37}[/tex] is a irrational number.

Next we have 0.1234

This is not a every going number.

There isnt a square root.

And it isnt a symbol.

So 0.1234 is a rational number.

Next we have [tex]-\sqrt{100}[/tex]

Again, we can immediatly know it has a square root.

So  [tex]-\sqrt{100}[/tex] is a irrational number.

Next we have -77

This is not every going.

It doesnt have a square root.

It doesnt have a symbol.

So -77 is a rational number.

Lastly we have   [tex]-\sqrt{12}[/tex]

Like the other ones, we can imediatly tell it has a square root.

So [tex]-\sqrt{12}[/tex] is a irrational number.

Bascially, to answer further questions, here is the criteria for a number being rational:

If one of these criterias are not met, then you know its a irrational number.

Step-by-step explanation:

Answer:

[tex]y = 2x - 5[/tex]

Substitute the value of y as 2x - 5 in the equation.

[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]

Now, find the value of y

[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]

⎇ x = x = x, equals 10

⎇ y = y = y, equals 15

Answer:

if y = 2x-5

then in the second equation we can find the value of x

5x-4(2x-5) = -10

5x-8x+20 = -10

-3x = -30

x = 10

then the value of y = 20-5 = 15

therefore the value of x = 10 and y =15 (ans)

The answer is 6x^2. To find this, just find the greatest factor of each question, aka the greatest "common" factor (GCF), of both since it is the greatest factor they each have in common. Hope this helps!

Answer:

odd; even; even; odd

Step-by-step explanation:

The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We know when the graph is symmetric about the origin it is an off function.

When the graph is symmetric about the y axis it is an even function.

When f(-x) = f(x) it is an even function

When f(-x) = -f(x) it is an odd function.

Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Answer:

75ft^2

Step-by-step explanation:

A = pi*r^2

The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.

Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.

3*(5)^2 = A

Simplify

3*25

Multiply

Area=75ft^2

Answer:

8.40

Step-by-step explanation: This means the cost of the item to you is $8.4. You will pay $8.4 for a item with original price of $12 when discounted 30%. In this example, if you buy an item at $12 with 30% discount, you will pay 12 - 3.6 = 8.4 dollars.

Answer:

The new total will be $8.40.

Step-by-step explanation:

The 30% off discount gives you $3.60 off of your purchase.

Answer:

2nd: 2

4th: -4

11th: -25

Step-by-step explanation:

When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:

A(2) = 5 + (2 - 1)(-3)

A(2) = 5 + (1)(-3)

A(2) = 5 - 3

A(2) = 2

To get the 4th term you substitute in 4:

A(4) = 5 + (4 - 1)(-3)

A(4) = 5 + (3)(-3)

A(4) = 5 - 9

A(4) = -4

And we do the same for the 11th term:

A(11) = 5 + (11 - 1)(-3)

A(11) = 5 + (10)(-3)

A(11) = 5 - 30

A(11) = -25

3:7

Last week Zoe received $24

Hence the amount received by Hannah can be calculated as follows

3/7= 24/x

168= 3x

x= 168/3

= 56

Hence Hannah received €56

Answer:

A. 6.75

Step-by-step explanation:

8x+18=4x+57

8x-4x=57-18

4x=39

4x+57=180-(8y+30)

39+57=180-8y-30

96=150-8y

8y=150-96

= 54

y= 54/8 = 6.75
