Answer:

18 Weeks

Step-by-step explanation:

The least amount of weeks that Irene must work in order to buy the bike is 18. To find your answer, subtract $70 from $250. You will get $180. This is the amount of money that Irene still needs to earn. If she saves her money for 18 weeks, she will have her $180. This is because $180 divided by $10 is 18.

Which of these is a unit of density?
Naddika [18.5K]
<h3><u>Answer:- </u></h3>

\longrightarrow \textsf{The unit of density is\;}\sf kg/m^3

<h3><u>Solution</u> :-</h3>

\green{ \underline { \boxed{ \sf{Density =  \frac{Mass}{Volume}}}}}

\longrightarrowThe unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³

<u>Some basic </u><u>derived </u><u>Units :- </u>

  • area => m²
  • volume cubic meter => m3
  • speed meter per second => m/s
  • acceleration => m/s²
  • mass density meter => kg/m3
  • specific volume cubic meter per kilogram m³/kg

How many ounces of a silver alloy that costs $5.50 per ounce should be mixed with one that costs $7.00 per ounce to make a new 3
Pepsi [2]

Answer:

<u>135.73 ounces</u> of a silver alloy that costs $5.50 per ounce should be mixed.

Step-by-step explanation:

Given:

A silver alloy that costs $5.50 per ounce should be mixed with one that costs $7.00 per ounce to make a new 30 ounce alloy that costs $6.40 per ounce.

Now, to find the ounces of silver alloy.

Let the silver costs $5.50 per ounce be x.

And the silver costs $7.00 per ounce be y.

So, the total ounce make a new alloy:

x+y=30\\y=30-x  ....(1)

Now, the total costs of silver alloy:

5.50x+7y=6.4

Putting the value of y from equation (1) in the place of y :

5.50x+7(30-x)=6.4

5.50x+210-7x=6.4

-1.5x+210=6.4

<em>Subtracting both sides by 210 we get:</em>

-1.5x=-203.6

<em>Dividing both sides by -1.5 we get:</em>

x=135.73

Therefore, 135.73 ounces of a silver alloy that costs $5.50 per ounce should be mixed.

M∠1=(3x+8)°​, m∠2=(3x+18)°​, and m∠3=(7x+9)°. What is m∠​3?
deff fn [24]

Answer:

87.4°

Step-by-step explanation:

(3x + 8) + (3x + 18) + (7x + 9) = 180

3x + 8 + 3x + 18 + 7x + 9 = 180

add the common numbers

13x + 35 = 180

subtract 35

13x = 145

divide 13

x = 11.2

then plug it back in to m<3

7(11.2) + 9

78.4 + 9

= 87.4°
