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

Step-by-step explanation:

Answer:

[tex]f(x) = 2x^3 -5x^2+2x+1\\\\by \ trail \ and \ error, \\\\f(1) = 2(1^3) -5(1^2) +2(1) +1 = 2 - 5 + 2 + 1 = 0\\\\Therefore, 1 \ is \ a \ root \ of \ f(x).\\\\=> (x -1) \ is \ a \ factor \ of \ f(x).[/tex]

Now using long division,

[tex]\quad \left(x-1\right)\left(2x^2-3x-1\right)\\\\(x-1)(x-\frac{3+\sqrt{17} }{4})(x+\frac{3-\sqrt{17} }{4} )[/tex]

Therefore , the roots are

Answer:

Subtract 8 from both sides, then divide both sides by 1/3.

Step-by-step explanation:

Since 8 is already negative, you would want to add 8, and since y is being multiplied by 3, you would want to divide it.

Subtract 8 from both side and divide both side by 1/3 will NOT solve this equation completely.

First-order equations are linear equations. The coordinate system defines the linear equations for lines. A linear equation in one variable is one in which there is only one variable and the equation has a homogeneous variable of degree 1. There can be more than one variable in a linear equation.

Given equation  -8 + 3y = 19

Condition 1:  Add 8 both sides, then divide both side by 3

-8 + 3y +8 = 19 + 8

3y =27; now divide by 3

3y/3 = 27/3

y = 9 (equation solved completely)

Condition 2: divide both side by 3, then add 8/3 both sides

(-8 + 3y)/3 = 19/3

-8/3 + y = 19/3; now add 8/3 both side

-8/3 + y + 8/3 = 19/3 + 8/3

y = 9  (equation solved completely)

Condition 3:  Add 8 both sides, then multiply both side by 1/3

-8 + 3y + 8 = 19 + 8

3y = 27; now multiply both side by 1/3

3y x 1/3 = 27 x 1/3

y = 9

Condition 4: Subtract 8 from both sides, and divide both side by 1/3

-8 + 3y - 8 = 19 - 8

3y - 16 = 11;  now divide both side by 1/3

(3y) ÷ 1/3 = 27 ÷ 1/3

9y = 9  (equation not solved completely)

Hence according to options, Subtract 8 from both sides, and divide both side by 1/3 not solves equation completely.

Step-by-step explanation:

If two ratios [tex]\frac{a}{b}[/tex] and [tex]\frac{c}{d}[/tex] are proportional,

[tex]\frac{a}{b}=\frac{c}{d}[/tex]

By applying this property for the given options,

Option 1

If the given ratios [tex]\frac{24}{31}[/tex] and [tex]\frac{20}{27}[/tex] are proportional.

[tex]\frac{24}{31}=\frac{20}{27}[/tex]

Which is false.

Therefore, ratios are not proportional.

Option 2

If the given ratios [tex]\frac{8}{9}[/tex] and [tex]\frac{24}{26}[/tex] are proportional,

[tex]\frac{8}{9}= \frac{24}{36}[/tex]

[tex]\frac{8}{9}= \frac{6}{9}[/tex]

False.

Therefore, given ratios are not proportional.

Option 3

If the given ratios [tex]\frac{16}{5}[/tex] and [tex]\frac{64}{20}[/tex] are proportional,

[tex]\frac{16}{5}=\frac{64}{20}[/tex]

Step-by-step explanation:

Answer:

Area of the image rectangle = 4(Area of the original rectangle)

Step-by-step explanation:

Length of the rectangle given in the graph = 4 units

Width of the rectangle = 2 units

Area of the rectangle = Length × Width

                                    = 4 × 2

                                    = 8  square units

Since, scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]

2 = [tex]\frac{\text{Length of the image}}{\text{Length of the original}}[/tex]

Length of the image rectangle = 2(4)

                                                   = 8 units

Similarly, width of the image rectangle = 2(2)

                                                     = 4 units

Area of the image rectangle = 8 × 4

Area of the image = Area of the original × 4

Area of the image = 4(Area of the original)

Area of the image rectangle = 4(Area of the original rectangle)

Answer:

50

Step-by-step explanation:

All three angles of a triangle will add up to 180. Since one angle is known, 90, the right angle, and another is known, 40, we can solve for the missing angle.

90 + 40 + x = 180

Add like terms.

130 + x = 180

Subtract 130 from both sides.

x = 50

The missing angle is 50.

Answer:

63°

Step-by-step explanation:

Triangle= 180°

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.

Answer:

Step-by-step explanation:

V = length * height * width = 18 * length * width

2,592 = 18 * length * width ; divide both sides by 18

144=  length * width ; now what 2 numbers multiplied are giving us 144?

1*144 = 144 ; 2*72 = 144 ; 3*48=144 ; 4*36 =144 ; 6*24 = 144 ; 8*18 = 144 ;

Answer: c

Step-by-step explanation:

The area of pentagon ABCDE is 36 times the area of pentagon PQRST. Therefore, the option C is the correct answer.

Any five-sided polygon or 5-gon is referred to as a pentagon. A basic pentagon's interior angles add up to 540°. A pentagon might be straightforward or self-intersecting.

We know the formula for the area of a pentagon, therefore, the area of the pentagon PQRST can be written as,

A= 1/4 ×√(5(5+25)×a²

Given that the side of the side length of pentagon ABCDE is 6 times the side length of pentagon PQRST, therefore, the area of the pentagon ABCDE can be written as,

Area of a ABCDE = 1/4 ×√(5(5+25)×(6a)²

= 1/4 ×√(5(5+25)×36a²

= 36A

Therefore, the option C is the correct answer.
