How do i solve this A=1/2bh for b

Answers

Answer 1

Answer: A = $(1)/(2)$ bh Multiply both sides by 2 to cancel out the fraction
2A = bh Divide both sides by h
$(2A)/(h)$ = b Switch the sides to make it easier to read
b = $(2A)/(h)$

Write down a number you can square to give an answer bigger than 400 but smaller than 500

Answers

If you would like to know a number you can square and the answer is bigger than 400 but smaller than 500, you can calculate this using the following step:

20^2 = 400 < 21^2 = 441 < 22^2 = 484 < 500

Three pirates named Ahab, Sparrow, and Davy play a game. The pirates have a total of 210 coins, and each pirate has a different number of coins. At the end of the game, Ahab has won 5 coins and Davy has won 7 coins. Now, the ratio of coins belonging to Ahab, Sparrow, and Davy is 4:5:6, respectively. How many coins did Sparrow have at the beginning of the game?

Answers

Sparrow has 92 coins, in the starting.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Total number of coins in game = 210.

And the ratio of coins belongs to Ahab, Sparrow and Davy = 4 : 5 : 6

Let the multiplying factor in ration is x

The number of coins to Ahab = 4x

Number of coins belongs to Sparrow = 5x

And number of coins belong to Davy = 6x

Since, total number of coins = 210

4x + 5x + 6x = 210

15x = 210

x = 16

Number of coins that Sparrow has = 5 x = 5 (16) = 80

At the end Ahab and Davy wins 5 and 7 coins respectively

So at the starting coins that Sparrow has = 80 + 7 + 5 = 92

The required coins that Sparrow has at the beginning is 92.

Step-by-step explanation:

at the end of game, sparrow has $(5)/(4+5+6) * 210=70$ coins. since he loss 5+7=12 coins, then at the beginning he has 70+12=82 coins

Please help with algebra 1) Mrs.Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.

Answers

It takes about 13 days for the revenue for each game the same.

Revenue is the amount of money made from selling a particular amount of products.

Given that the revenue is given by:

Math Game: M(d)=x²-9x-10

Reading Game: R(d)=2x+10

For both games to have the same revenue, hence:

M(d) = R(d)

x² - 9x - 10 = 2x + 10

x² - 11x - 20 = 0

x = -1.6 or x = 12.6

Since the number of days cannot be negative, hence it takes about 13 days for the revenue for each game the same.

Step-by-step explanation:

Given the following expression;

Math Game: M(d)=x^2-9x-10

Reading Game: R(d)=2x+10

x is the number of days since the games went on sale

In order to determine after how many days the revenue for each game wil be the same, we will equate M(d) to R(d)

M(d) = R(d)

x^2-9x-10 = 2x+10

x^2-9x-10-2x-10 = 0

x^2-11x-20 = 0

factorize

x = 11±√121-4(-20)/2

x = 11±√121+80/2

x = 11±√201/2

x = 11±37.16/2

x = 11+37.16/2

x = 48.16/2

x = 24.06

Hence the revenue for each game will be the same after 24 days
