Answer:

  5 5/6 hours

Step-by-step explanation:

We can add the times, but it is more convenient to use multiplication.

  5(3/6) + 4(5/6) = (15/6) +(20/6) = 35/6 = 5 5/6

Moira swims 5 5/6 hours each week.

Answer:

average monthly balance = $43

Step-by-step explanation:

If we have a set of N numbers:

{x₁, x₂, x₃, ..., xₙ}

The mean (or average) is calculated as:

Mean = (x₁ + x₂ + ... + xₙ)/N

In this case, the values on the set are the balances for every month.

Then our set is:

{$50, $25, $70, $45, $25}

This is a set of 5 elements.

Then the average monthly balance is:

average monthly balance = ($50 + $25 + $70 + $45 + $25)/5 = $43

average monthly balance = $43

Answer: 40%

Step-by-step explanation:

There are 70 cookies in total.

The gingerbread cookies number 28.

The percentage that are gingerbread will therefore be:

= Number of gingerbread/ Total number of cookies * 100%

= 28 / 70 * 100%

= 40%

Answer:

Left: yes it is linear

Right: No it is not.

Step-by-step explanation:

Left Problem

The table on the left is linear. It's general form is

y = 6x + 7

x = 5

y = 5*6 + 7

y = 37

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

x = 8

y = 6*8 + 7

y = 48 + 7

y = 55

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

y = 6*12 + 7

y = 72 + 7

y = 79

=============

Right Problem

The right problem looks like it is linear. It is not, I don't think. Do the same thing you did above.

y = 62x

x = 2

y = 2*62

y = 124

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

y = 62x

x = 6

y = 62 * 6

y = 372

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

y = 62*x

x = 9

y = 62 * 9

y = 558            

It should be 558 not 552

Answer:

67.4°, C = 53.6°, c = 12.2; B = 112.6°, C = 8.4°, c = 2.2

a/sinA=b/sinB=c/sinC

a/sinA=13/0.8572=15.1662

sinB=b/a *sinA

sinB=14/13 *sin59=0.9231

B=67.4

B1=90+22.6=112.6

because sin67.4=sin112.6=0.9231

C=180-59-67.4=53.6

C1=180-59-112.6=8.4

c=a* sinC/sinA=13* sin53.6/sin59=12.2

c1=a* sinC1/sin59=13*sin8.4/sin59=2.2

Answer: y=5(x+15)2−26 5

Notice that the square root is accompanied with ^2 and can be simplified:

This works because 4x^4 = (2x^2)^2

[tex]\sqrt{(2x^{2})^{2} * (256y^{8})^{2} }[/tex]

Remove the square root:

[tex]2x^{2} (256y^{8} )[/tex]

Calculate the product:

[tex]512x^{2} y^{8}[/tex]

This is your answer after simplification.

Answer: He watched 9 episodes over winter break.

Step-by-step explanation:

Given: Total episodes watched = 45

After school started , he watched 9 episodes per week.

So in 4 weeks. he watched = 9 x 4 = 36 episodes.

Number of episodes he watched over winter break = 45-36

i.e. Number of episodes he watched over winter break = 9

Hence, he watched 9 episodes over winter break.

Answer:

32 m^2

Step-by-step explanation:

First find the volume of the bottom section

V = l * w*h

V = 6 * 2 * 2 = 24 m^2

Then find the volume of the top section in green

The length is 6-4 =2,  the height is 4-2, width is 2

V = = l*w*h = 2*2*2 = 8

Ad the volumes together

V = 24+8 = 32 m^2

Answer:

t = 1.025c + 5.99

Step-by-step explanation:

The shipping charge, = $5.99

Tax paid on purchases = 2.5%

Cost of item, c

Total cost, t, including shipping and tax

Total cost = Cost of item + tax on purchase +. Shipping fee

Tax on purchase : 2.5% * cost of item

Tax on purchase : 0.025c

Shipping = $5.99

General formula for a linear equation :

y = mx + c

Hence, for the cost model:

Total cost = Cost of item + tax on purchase +. Shipping fee

t = c + 0.025c + 5.99

t = 1.025c + 5.99

Answer:

V=634.0 cubic meter.

Step-by-step explanation:

By formula   V=πr^2(h/3)

so  V=π5.8^2(18/3)

then 5.8square2 =33.64 ,18/3=6  and pi  

multiply everything you'll get  V=634.0990612

finally it says round to the nearest tenth which mean , V=634.0 cubic meter.

Answer:

y= -2x + 11

Step-by-step explanation:

standard form for lines is y=mx+b

m is the slope and b is the y intercept

we already know that m is -2, so we just need to figure out the intercept.

the point given is (7,-3)

points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y

-3 = -2 (7) + b

-3 = -14 + b

11 = b

so the equation is y=-2x+11

Answer:

x<110

Step-by-step explanation:

-x/10>-11

-x>-11*10

-x>-110

x>110

x<110

Answer:

x > - 110

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the greater than a sign from both sides of the inequality :

       x / 10 - ( -11 ) > 0

                  x

Simplify   ——

                 10

   x    

 —— -  -11  > 0

  10

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  10  as the denominator :

              -11                -11 • 10

   -11 =  ———  =  ————————

               1                     10  

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

  x - (-11 • 10)               x + 110

———————  =  ———————

      10                            10

       x + 110

 ———————  > 0

          10

Multiply both sides by  10

Subtract  110  from both sides

           x > -110

Answer:

9/40

Step-by-step explanation:

120 × ⅖ = 48

120 × ⅜ = 45

120 - 93 = 27

27/120 = 9/40

Based on the proportions and the counters in the bag, the fraction that is green is 9 / 40.

You can find the number of green counters by:

= Number of counters - Red counters - Yellow counters

= 120 - (120 x 40%) - (120 x 3/8)

= 120 - 48 - 45

= 27 green counters

= Number of green counters / Total number of counters

= 27 / 120

To take it to the lowest term, divide both numbers by 3:

= 9 / 40

In conclusion, the fraction is 9 / 40.
