Answers

Answer 1

Answer:

m∡1 = 91°

Step-by-step explanation:

5x+14+7x-14 = 180

12x = 180

x = 15

m∡2 = 5(15)+14 = 89

m∡1 = 180 - 89 or 91°

Ms. Murray has a collection of 25 dimes and nickels. How many nickels does Ms. Murray have if she has a total of $2.30?

Answers

four nickels,
because 1 dime=10¢ and so 21 x .10 = 2.10 and 1 nickel=5¢ so .05 x 4 = .20

2.10 + .20 = 2.30

I’m not sure if the explaining made sense but it’s 4 nickels :)

Ann took a taxi home from the airport. The taxi fare was $2.10 point, 10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10,

Answers

Answer: 21 miles

Step-by-step explanation:

Here's the remainder of the question:

Write an equation to determine the distance in miles x between the airport and Ann's home.

We are informed that the taxi fare was $2.10 per mile, and she gave the driver a tip of $5 Ann paid a total of $49.10, this can be expressed into an equation as:

(2.10 × x) + 5 = 49.10

2.10x + 5 = 49.10

2.10x = 49.10 - 5

2.10x = 44.10

x = 44.10 / 2.10

x = 21

The distance between the airport and Ann's home is 21 miles.

Estimate 72.91 + 67.526 by first rounding each number to the nearest whole number

Answers

Answer:

141

Step-by-step explanation:

First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)

Answer: 141

Step-by-step explanation: By rounding up to the nearest whole number, that is taking 72.91 -> 73. The reason it is this way is that when a decimal is past 0.5, you round up. If a decmial is below 0.5, then you round down.

In this specific situation, we get the numbers 72.91 and 67.526.

As I explained, the numbers would round up because both numbers decimal values are above 0.5.

So after 72.91 is 73, and after 67.526 is 68.

68 + 73 =

141

KN ≈ 20.7 cm

Step-by-step explanation:

Using Pythagoras' identity in right triangle KLM to find KM

LM² = KL² + KM²

28² = 16² + KM²

784 = 256 + KM² ( subtract 256 from both sides )

528 = KM² ( take the square root of both sides )

[tex]\sqrt{528}[/tex] = KM

----------------------------------------

Using the sine ratio in right triangle KMN

sin64° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{KN}{KM}[/tex] = [tex]\frac{KN}{\sqrt{528} }[/tex] ( multiply both sides by [tex]\sqrt{528}[/tex]

[tex]\sqrt{528}[/tex] × sin64° = KN , that is

KN ≈ 20.7 cm ( to 1 dec. place )

Answer is 16 because 16/4 = 4 + -12 = -8

Answer:

m=16

Step-by-step explanation:

-8=m/4+(-12)

4=m/4

16=m

so first, you add 12 to the other side to cancel out the -12. 12-8=4. so now you have 4=m/4. to isolate the m, you have to multiply by 4 on both sides, which gives you 16=m or m=16.
