Two numbers add to 336 and the first is 126 bigger than the five times the second. What are the two numbers?

Answers

Answer:

301, 35

Step-by-step explanation:

1st number = x, 2nd = y

x + y = 336

x = 126 + 5y

Then

(126 + 5y) + y = 336

6y = 336 - 126 = 210

y = 210/6 = 35

x = 126 + 5y = 126 + 5*35 = 301

Or x = 336 - 35 = 301

The two numbers are 301 and 35

PLSSS PATULONG PO

Answers

Answer:

Rule: A=50n

Step-by-step explanation:

Because each purse is 50 pesos, and n is the number of purses, and 50n would be the total cost, otherwise known as A.

Our rule is: A=50n

Then we insert 3 values for n, and solve to get the ordered pairs.

n=3 purses, A=3*50=150 dollars

n=4 purses, A=200 dollars

n=5 purses, A=250 dollars

Step-by-step explanation:

4cd - 25c^2 - 0.16d^2

= 4cd - (5c)^2 - (0.4d)^2

= -[(5c)^2 -2*5*0.4cd + (0.4d)^2]

If you used a random number generator for the numbers from 1 through 20 to play a game, what is the theoretical probability of getting each of these outcomes?

a. A multiple of 3 or a multiple of 7, P(multiple of 3 or multiple of 7)

b. P(even or odd)

c. P(prime or 1)​

Answers

Answer: See below

Step-by-step explanation:

Game 1:

20 total numbers

Probability = Multiples of 3 and 7/Total Numbers

P = 8/20

P = 2/5 or 40%

Game 2:

20 total even or odd numbers

Probability = Number of even and odd/Total Numbers

P = 20/20

P = 1 or 100%

Game 3:

8 prime numbers and 1 = 9 total

Probability = Number of prime numbers or 1/Total Numbers

P = 9/20 or 45%

a) The probability of a multiple of 3 or a multiple of 7 is 40%.

b) The probability of even and odd is 100%.

c) The probability of the number being prime is 45%.

What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Game 1:

20 total numbers

Probability = Multiples of 3 and 7/Total Numbers

P = 8/20

P = 2/5 or 40%

Game 2:

20 total even or odd numbers

Probability = Number of even and odd/Total Numbers

P = 20/20

P = 1 or 100%

Game 3:

8 prime numbers and 1 = 9 total

Probability = Number of prime numbers or 1/Total Numbers

P = 9/20 or 45%

A 24 cm²

Answers

Answer:

area of ΔABC = 48 cm²

Step-by-step explanation:

We have been provided with height of 6 cm and have to find base.

using Pythagoras theorem:

a² + b² = c²

a² + 6² = 10²

a² = 100 -36

a² = 64

a = √64

a = 8

Area of both triangles:

[tex]\frac{1}{2}[/tex] * base * height

[tex]\frac{1}{2}[/tex] * 8 * 6

24 cm²

area of both triangles: 24 cm² * 2 = 48 cm²

Apply Pythagorean theorem

[tex]\\ \tt\hookrightarrow AN^2=8^2[/tex]

[tex]\\ \tt\hookrightarrow AN=8cm[/tex]

2+ x + 4+x= 2x + 6

2x + 17 = 3x +6

3x-2x = 17-6

Number lines are used to represent numbers and ratios using regular intervals

Nuka can weave 8.75 cm of strip in 5 minutes

How to determine the length of strip

Represent the ratio with:

Ratio = Length : Time

From the number line, they can weave 7cm of the strip in 4 minutes.

So, we have:

Ratio = 7cm : 4 minutes

Represent the length of strip made in 5 minutes with x.

So, we have:

x : 5 minutes = 7cm : 4 minutes

Remove the common units

x : 5 = 7cm : 4

Express as fraction

[tex]\frac x5 = \frac 74[/tex]

Divide 7 by 4

[tex]\frac x5 = 1.75[/tex]

Multiply through by 5

[tex]x= 8.75[/tex]

Hence, Nuka can weave 8.75 cm of strip in 5 minutes

The Perimeter of the

Find the Base.

Answers

Answer:

base = [tex]x^4 - 3x^3+11x-4[/tex]

Step-by-step explanation:

An isosceles triangle has 2 sides of equal length (a) and base (b)

⇒ perimeter of an isosceles = 2a + b

Given:

[tex]\textsf{leg (a)}=3x^4 - 6x-1[/tex]  [tex]\textsf{perimeter}=7x^4 - 3x^3-x-6[/tex]

[tex]\implies \textsf{perimeter}=2a+b[/tex]

[tex]\implies 7x^4 - 3x^3-x-6=2(3x^4 - 6x-1)+b[/tex]

[tex]\implies 7x^4 - 3x^3-x-6=6x^4 - 12x-2+b[/tex]

They each have 4 million labor hours available per month that they can use to produce rye, jeans, or a combination of both. The following table shows the amount of rye or jeans that can be produced using 1 hour of labor. Country Rye Jeans (Bushels per hour of labor) (Pairs per hour of labor) Euphoria 4 16 Bellissima 6 12 Initially, suppose Bellissima uses 1 million hours of labor per month to produce rye and 3 million hours per month to produce jeans while Euphoria uses 3 million hours of labor per month to produce rye and 1 million hours per month to produce jeans. Consequently, Euphoria produces 12 million bushels of rye and 16 million pairs of jeans, and Bellissima produces 6 million bushels of rye and 36 million pairs of jeans. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of rye and jeans it produces. Euphoria's opportunity cost of producing 1 bushel of rye is __(1/2, 1/4, 2, 4)___ pairs of jeans, and Bellissima's opportunity cost of producing 1 bushel of rye is __(1/2, 1/4, 2, 4)___ of jeans. Therefore, __(Euphoria or Bellissima)__ has a comparative advantage in the production of rye, and___ (Euphoria or Bellissima)__ has a comparative advantage in the production of jeans. Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces rye will produce____million bushels per month, and the country that produces jeans will produce____million pairs per month. In the following table, enter each country's production decision on the third row of the table (marked "Production"). Suppose the country that produces rye trades 14 million bushels of rye to the other country in exchange for 42 million pairs of jeans. In the following table, select the amount of each good that each country exports and imports in the boxes across the row marked "Trade Action," and enter each country's final consumption of each good on the line marked "Consumption." When the two countries did not specialize, the total production of rye was 18 million bushels per month, and the total production of jeans was 52 million pairs per month. Because of specialization, the total production of rye has increased by____million bushels per month, and the total production of jeans has increased by____million pairs per month. Because the two countries produce more rye and more jeans under specialization, each country is able to gain from trade. Calculate the gains from tradethat is, the amount by which each country has increased its consumption of each good relative to the first row of the table.
