b. 60:45 and 4:3 why is it equivalent.​

Answers

Step-by-step explanation:

60:45 in fraction form is [tex]\frac{60}{45}[/tex], and reducing it to its simplest form by dividing the fraction by [tex]\frac{15}{15}[/tex] gives you:

[tex]\frac{60}{45}[/tex] ÷  [tex]\frac{15}{15}[/tex] = [tex]\frac{4}{3}[/tex]

Likewise, 4:3 in fraction form is [tex]\frac{4}{3}[/tex].

Therefore, 60:45 and 4:3 are equivalent.

find all the zeros of the quadratic function y=x²-9x+20

Answers

Answer:

Roots: x = 5; x = 4

Step-by-step explanation:

Given the quadratic equation, x² -9x + 20 = 0

where a = 1, b = -9, and c = 20

Determine the nature and number of solutions based on the discriminant, b² - 4ac:  

b² - 4ac = (-9)² - 4(1)(20) = 1

Since b² - 4ac > 0, then it means that the equation will have two real roots.

Use the Quadratic Formula:

[tex]x = \frac{-b +/- \sqrt{b^{2} - 4ac} }{2a}[/tex]

[tex]x = \frac{-(-9) +/- \sqrt{(-9)^{2} - 4(1)(20)} }{2(1)}[/tex]

[tex]x = \frac{9 +/- \sqrt{1}}{2}[/tex]

[tex]x = \frac{9 + 1}{2}; x = \frac{9 - 1}{2}[/tex]

[tex]x = \frac{10}{2}; x = \frac{8}{2}[/tex]

x = 5; x = 4

Therefore, the roots of the quadratic equation are: x = 5; x = 4.

The answer pleaseeee

Answers

Step-by-step explanation:

given,

x = 12

y = 4

therefore according to

F. y = 1/3x

4 = 1/3×12 1×4 = 4

4 = 4

G. y = 3x

4 = 3(12) = 36

4 36

H. y = 48/x

4 = 48/12

4 = 4

J. y = x - 8

4 = 12 - 8

4 = 4

therefore, F , H and J represents this relationship.

We know that mid - point of a line segment divides it into two equal parts, that is it divides the segment in the ratio of 1 : 1, so let's find the coordinates of the mid point of line segment joining points (-9 , 3) and (5 , 7).

let the coordinates of the points be x and y, now

[tex]m = 1[/tex]

[tex]n = 1[/tex]

[tex]x_2 = 5[/tex]

[tex]x_1 = - 9[/tex]

[tex]y_2 = 7[/tex]

[tex]y_1 = 3[/tex]

Using section formula :

value of x :

[tex]x = \dfrac{mx_2 - nx_1}{m + n} [/tex]

[tex]x = \dfrac{(1 \times 5) - (1 \times - 9)}{1 + 1} [/tex]

[tex]x = \dfrac{5 - ( - 9)}{2} [/tex]

[tex]x = \dfrac{5 + 9}{2} [/tex]

[tex]x = \dfrac{14}{2} [/tex]

[tex]x = 7[/tex]

value of y :

[tex]y = \dfrac{my_2 -ny_1 }{m+ n} [/tex]

[tex]y = \dfrac{(1 \times 7) - (1 \times 3)}{1 + 1} [/tex]

[tex]y = \dfrac{7 - 3}{2}[/tex]

[tex]y = \dfrac{4}{2} [/tex]

[tex]y = 2[/tex]

So, coordinates of the point which is midpoint of the given line is :

[tex] \boxed{ \boxed{ (7, 2)}}[/tex]

Aluminum bronze consists of copper and aluminum, usually in the ratio of 10:1 by weight. If an object made of this alloy weighs 77 pounds, how many pounds of aluminum does it contain?

Answers

Answer:

The correct answer is (A). Copper and aluminum in the ratio of 10:1 means 10 parts copper to 1 part aluminum.

Step-by-step explanation:

7 pounds of aluminum in aluminum bronze by by weight.

What is Ratio?

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

What is percentage?

The percentage is defined as the ratio expressed as a fraction of 100.

The percentage is denoted by sign of %.

For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.

Aluminum bronze consists of copper and aluminum in the ratio of 10:1 by weight

The ratio of copper and aluminum in aluminum bronze = 10:1

Let, aluminum in aluminum bronze by weight = x pound

And copper in aluminum bronze by weight = 10x pound

Since object made of this alloy weighs 77 pounds

So, x + 10x = 77

11x = 77

x = 7

Hence, 7 pounds of aluminum in aluminum bronze by by weight

Retirement Account. What fraction is this? *
1/2
22/100
2/3
29/200

Answers

Answer:

29/200

Step-by-step explanation:

Turn all fractions into percentages by dividing the numerator by the denominator then multiply the quotient by 100 to get it in percent.

1/2 = 50%

22/100 = 22%

2/3 = 66.7%

29/200 = 14.5%

Now that we turned all fractions into percents, we can see that 29/200 is that answer since its percentage is 14.5%.
