Alexander has nickels, dimes, and quarters in the ratio of 2:1:8, if 40 of Alexander's coins are quarters, how many nickels and dimes does Alexander have?

Answers

Answer 1

Answer:

He has 10 nickels and 5 dimes

Step-by-step explanation:

We can take advantage of the ratio by dividing 40 by 8, giving us that every 1 in the ratio = 5. So we can multiply 2 x 5 = 10 and 1 x 5 = 5.

Hope this Helps!

Answers

Answer:

[tex]\$843.67[/tex]

Step-by-step explanation:

Let's break the price changes down:

Initial price: $896

On sale for 12%, meaning the computer will be 100-12=88% of the original price:

New sale price [tex]\implies896\cdot 0.88=\$788.48[/tex]

Now a 7% tax is added to this, meaning the final price will be 107% of this new sale price.

Final price [tex]\implies 788.48\cdot 1.07\approx \boxed{\$843.67}[/tex]

Answers

Answer:

36

Step-by-step explanation:

Square roots have a neat property: [tex]\sqrt{ab}=\sqrt{a}\sqrt{b}[/tex] provided a and b are positive real numbers.

This property is what's behind simplifying square roots.  You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.

Example: [tex]\sqrt{20}=\sqrt{4\times5}=\sqrt{4}\sqrt{5}=2\sqrt{5}[/tex].

In this problem, both factors are perfect squares.

[tex]\sqrt{9\times144}=\sqrt{9}\sqrt{144}=3\times12=36[/tex]

Use the fundamental counting principle to find the total number of outcomes in each situation. Selecting a year in the last decade and a month of the year.

Answers

Answer:

120 different outcomes

Step-by-step explanation:

Selecting a year in the last decade ; this means selecting a year from from the last decade :

Number of years jn decade = 10

Selecting a month of the year : number of months in a year = 12

Hence, we have :

10 * 12 = 120 different outcomes

A youth club leader plans a walk to raise money for charity. The route measures 40 centimeters on a map. The scale on the map is 5 centimeters to 1 kilometer. How long is the actual route?

Answers

Answer:

8 km

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

40 / 5 = 8km

-x+9y=-5
x-5y=1

Answers

Let's solve for x.

−x+9y=−5

Step 1: Add -9y to both sides.

−x+9y+−9y=−5+−9y

−x=−9y−5

Step 2: Divide both sides by -1.

−x ÷ −1 = −9y−5 ÷ −1

x=9y+5

THE ANSWER FOR THE OTHER EQUATION: (x-5y=1)

Let's solve for x.

x−5y=1

Step 1: Add 5y to both sides.

x−5y+5y=1+5y

x=5y+1

Answer:

x=5y+1

A rectangle is 2x-3 in by 3x-1 in. Find the area.

Answers

Answer:

[tex]\huge\boxed{A=6x^2-11x+3;\ \text{for}\ x>1.5}[/tex]

Step-by-step explanation:

The formula of an area of a rectangle:

[tex]A=a\cdot b\\\\a,\ b-\text{sides of a rectangle}[/tex]

We have:

[tex]a=2x-3\\b=3x-1[/tex]

The domain:

[tex]2x-3>0\ \wedge\ 3x-1>0\\\\2x-3+3>0+3\ \wedge\ 3x-1+1>0+1\\\\2x>3\ \wedge\ 3x>1\\\\\dfrac{2x}{2}>\dfrac{3}{2}\ \wedge\ \dfrac{3x}{3}>\dfrac{1}{3}\\\\x>1.5\ \wedge\ x>\dfrac{1}{3}\Rightarrow\boxed{x>1.5}[/tex]

Substitute:

[tex]A=(2x-3)(3x-1)[/tex]

use FOIL: (a + b)(c + d) = ac + ad + bc + bd

[tex]A= (2x)(3x)+(2x)(-1)+(-3)(3x)+(-3)(-1)\\\\A=6x^2-2x-9x+3[/tex]

combine like terms

[tex]A= 6x^2+(-2x-9x)+3\\\\A=6x^2-11x+3[/tex]

Answer:

6x² - 11x + 3

Step-by-step explanation:

To find the area of a rectangle, we multiply the length by the width.

A = l • w

length: 2x-3

width: 3x-1

A = (2x-3) • (3x-1)

To multiply these two binomials, we must FOIL (first | outer | inner | last) them.

F: 2x • 3x = 6x²

O: 2x • -1 = -2x

I: -3 • 3x = -9x

L: -3 • -1 = 3

Combine the terms.

6x² - 2x - 9x + 3

Combine like terms.

6x² - 11x + 3

This is your area.

The numerator of fraction is 1 less then its denominator if the numerator is increased by 5 the new fraction becomes equivalent to 4/5 what is the original factor?

Answers

Answer:

4/5

Step-by-step explanation:

the numerator of fraction is 1 less than its denominator. If the numerator is increased by 4 and the denominator is increased by 5, the new fraction becomes equivalent to 4/5. what is the original fraction?

Let n = numerator

d = denominator

n = d - 1

[tex]\frac{d - 1}{d}[/tex]

[tex]\frac{d - 1 + 4}{d + 5}[/tex] = [tex]\frac{4}{5}[/tex]

[tex]\frac{d + 3}{d+ 5}[/tex] = [tex]\frac{4}{5}[/tex]

cross multiply

5(d + 3) = 4(d + 5)

5d + 15 = 4d + 20

d = 5

n = d - 1

5 - 1 = 4

original fraction 4/5

Ahhhhhhhhhhhhhhhhhhhhhhh someone plzzzzz help

Answers

Answer:

15, 80

Step-by-step explanation:

1) I am assuming the first picture is a 90 degree angle total, because the question can't be solved without that assumption.

  90 - 75 = 15

  x = 15

2) The whole angle is 180 so 180 - 75 - 25 = CAD

  CAD = 80

Answer:

15° and 80°

Step-by-step explanation:

for the first one since its a right angle then its equal to 90 degrees

90-75 = 15     x=15°

for the second one since the line is a straight line then put it equal to 180

25+75+x=180

100+x=180

x=80°

You roll a cube with the numbers 13, 16, 18, 20, 22, and 24 on it. You then spin a spinner which has 6 sections. The letters on the spinner are E, B, G, K, D, and H. Find the P(G and prime number). Write your answer as a fraction or a decimal​

Answers

Answer:  1/36

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

Explanation:

The only prime number of the list of values given is the value 13. This is because the only factors are 1 and 13. Something like 24 isn't prime because 2 is a factor.

The probability of rolling to get a prime number is 1/6 because there is one prime out of 6 total values listed.

The probability of spinning on "G" is also 1/6 because there is only one section labeled "G" out of 6 sections total.

Assuming both events are independent, we multiply the probabilities to get (1/6)*(1/6) = 1/36 which represents the probability of rolling a prime number and spinning on G.

Side note: 1/36 = 0.0278 = 2.78% approximately
