Evaluate the expression when b=9 and c=4 . bc+12.3 =

Answers

Answer 1
48.3

9*4 = bc, equals 36
36+12.3, equals 48.3
Answer 2
48.3 because when two letters are next to each other and they are worth a number you multiply them for example 9(4)+12.3 so first you multiply 9 and 4 you should get 36 then you add 12.3 which will get you 48.3

Answers

Answer:

[tex]\sqrt19[/tex]

Step-by-step explanation:

First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,

9^2 + b^2 = 10^2.

solve, 81 + b^2 = 100

then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].

Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.

4^2 + x^2 = 19.

Solve

16 + x^2 = 19

Subtract 16 from both sides

x^2 = 19

and finally, we take the square root of both sides

x = [tex]\sqrt19[/tex]

Square root of 19 would be your answer

Answer:

40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Answer:

 40

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.

a store sells laptops for 720 each. this price is 20 percent more than what it cost the store to buy each of them. before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost cost. how much would it cost an employee to purchase one of these laptops at the sale?

Answers

Answer:

462

Step-by-step explanation:

720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.

720*5/6= 600

The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.

600*0.77 = 462

The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.

Given :

A store sells laptops for 720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.

The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:

Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.

Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:

[tex]=\dfrac{720}{120}\times 100[/tex]

= 600

Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.

Step 4 - So, the total cost of the laptop at which an employee purchase is:

[tex]=\dfrac{77}{100}\times 600[/tex]

= 462

Step-by-step explanation:

Hey there!

1,000 - 100 + 10 - 1

1,000 - 100 = 900

= 900 + 10 - 1

900 + 10 = 910

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.

Answers

Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

equation: 20/c= 3.00c

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.

Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00

Answers

Answer:

y = a(.10) + 25

Step-by-step explanation:

Using the equation y = ax + b.

"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."

The word "per" indicating that you are multiplying this.

The only variables being multiplied are a and x.

Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.
