Answer: It takes Him 1/4 hours to decorate both signs,

Step-by-step explanation:

Hi, since the area of a rectangle is equal to:

Area: length x width

Replacing with the values given;

Sign 1 =A1 = 2/3 x 1/4 =1/6 ft2

Sign 2 =A2= 1/2 x 1/3 = 1/6 ft2

If we sum both areas:

A1 +A2 = 1/6 + 1/6 = 2/6 ft2 = 1/3 ft2 (total area)

Since it takes Roberto 3/4 hour to decorate a 1-square-foot sign:

For 1/3 ft2

3/4 hour x 1/3 ft2 = 1/4 h

ITt takes Him 1/4 hours to decorate both signs,

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40
Alexxandr [17]

Answer:

Step-by-step explanation:

Let the number of ounces of

A = x

B = y

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?

Our system of equations is given as

x + y = 90.... Equation 1

x = 90 - y

40% × x + 55% × y = 45% × 90 ounces

0.4x + 0.55y = 40.5....Equation 2

We substitute 90 - y for x in Equation 2

I don’t understand. and someone please help?
givi [52]

Solution:

<u>Note that:</u>

  • 6x + 26 = 92 (Vertically opposite angle)
  • 92 + 92 + z + z = 360

<u>Finding x.</u>

  • 6x + 26 = 92
  • => 6x = 92 - 26
  • => 6x = 66
  • => x = 11

<u>Finding z.</u>

  • 92 + 92 + z + z = 360
  • => 184 + 2z = 360
  • => 2z = 360 - 184
  • => 2z = 176
  • => z = 176/2 = 88

Evaluate. –1.65 + (–3.4)
elena55 [62]
Hey there! 

This seems like a algebraic expression

SO,
Remember: negative and negative = positive
                      positive and positive = positive
                     positive and negative = negative
                       negative and positive = negative

In this problem we will be doing negative and negative so that means our answer will be a negative 

Firstly, lets line up our decimals to solve this problem (once when you do that , you can solve it easier)

-1.65 &#10;\\ +&#10;\\ (-3.4)&#10;

Answer: 
-5.05

Good luck on your assignment and enjoy your day
