Answer:

s=1

Step-by-step explanation:

Using the diagram, we can see that the angle is a right angle.

With this information, we can set up an equation:

77+8s+5=90

Please note that right angles are always equivalent to 90 degrees.

77+8s+5=90

Add like terms:

82+8s=90

Subtract 82 from both sides:

8s=8

Divide both sides by 8

s=1

X + (2x + 40) + (3x – 50) = 15,002
Rufina [12.5K]
Hello there!

x + (2x + 40) + (3x - 50) = 15002

Remove the parentheses

x + 2x + 40 + 3x - 50 = 15002

Combine like terms

x + 2x + 3x + 40 - 50 = 15002

6x - 10 = 15002

6x = 15002 + 10

6x = 15012

x = 15012/6

x = 2502


As always, it is my pleasure to help students like you!

Order the numbers from least to greatest.
Marianna [84]

Answer:

Step-by-step explanation:

Unfortunately, your π2 is improperly formed.  I will assume that you actually meant π² ("pi squared").

Then the three numbers are 99, 9.87, 9.8.

Smallest:  9.8

Largest"  99 (did you mean 9.9?)

Under the assumptions I have made, the numbers, in increasing order, are 9.8, 9.87, 99

Answer:

A. you need 2 1/2 ounces

B. you need 73,9 milliliters

Step-by-step explanation:

A

We have the ratio 1/2 ounces per gallon

And the mop bucket holds 5 gallons

Then we need to multiply 1/2*5

we got 2 1/2 ounces of desifectant per 5 gallons

B

1 ounces equal 29,57 milliliters

if we have 2 1/2 ounces then we multiply 2,5 *29,57

the answer is 73,9 milliliters
