Answer:

105cm2

Step-by-step explanation:

area= area f rectangle + area of trapezium

        = (6x9)+( [tex]\frac{6+11}{2}[/tex]x6)

         = 54+51

        = 105 cm2

Answer:

Yes, they are

Step-by-step explanation:

y = -9x

Here y∝ x

Where -9 is constant of proportionality

If "y" increases by factor of 2, then "x" will also increases by factor of 2. Hence, y and x are " directly proportional" to each other.

Answer:

cost of a box is $3.5

Step-by-step explanation:

given data

sold box = 18

earned = $136.50

solution

we consider here number of boxes of cookies is x

and

for we get Tyler sold  cookies box so number of boxes we divide 702 cookies among 18 is

Tyler sold  = [tex]\frac{702}{18}[/tex]

Tyler sold  = 39 boxes

and

now we consider here y as cost of each box of cookies,

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes

so

cost of each box = [tex]\frac{136.5}{39}[/tex]

cost of each box = 3.5

Thus, the cost of each box was 3.5

Answer:

1/10

Step-by-step explanation:

Answer:

t = 1

Step-by-step explanation:

When you cross multiply the equation becomes:

10(t+8)=10(9)

Now, solve for t.

10(t-8) = 10(9)

10t+80= 90

   -80    -80

   10t÷10  =   10÷10

           t = 1

Answer:21,600 feet per hour

Step-by-step explanation:

60*60=360 (multiplying the distance traveled per second by the number of seconds in a minute to get how far the person traveled in a minute)

360*60=21,600 (multiplying the distance travels in a minute by the number of minutes in an hour to find the total distance traveled in an hour)

Answer:

Cost price of the fan is [tex]\text {Rs. 470.59}[/tex].

Step-by-step explanation:

Given: A man sold a fan for  [tex]\text{Rs.}\:400[/tex]. He incurred a loss of [tex]15\%[/tex].

To find: The cost price of the fan

Solution:

We have,

Selling price, S.P.,  of the fan [tex]= \text{Rs.} 400[/tex]

Loss [tex]=15\%[/tex]

We know that [tex]\text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%[/tex]

Now let the C.P. of the fan be [tex]\text{Rs.} \:x[/tex]

So, [tex]15=(\frac{x-400}{x})\times 100[/tex]

[tex]\implies 15x=100x-40000[/tex]

[tex]\implies 100x-15x=40000[/tex]

[tex]\implies 85x=40000[/tex]

[tex]\implies x=\frac{40000}{85}[/tex]

[tex]\implies x= 470.59[/tex]

Hence, the cost price of the fan is [tex]\text {Rs. 470.59}[/tex].

Answer: y = x + 2 OR f(x) = x + 2

Step-by-step explanation:

Calculating slope:

Remember rise over run; when going from one point to another point, in this case from (-3, -1) to (0,2), locate the distance moved in the x and y directions. This scenario moves 3 up and 3 right, meaning a positive slope of one. However, if the line was directed left, your slope would be negative.

Finding y-intercept:

Where does the line intersect the y-axis and have a x-value of 0? This is your y-intercept --> (0,2).

Write Equation:

y = mx +b

y = 1x + 2

y = x + 2 (your final answer)

Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!

Step-by-step explanation:

Answer:

(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

Step-by-step explanation:

Given the expression

3-6y² and y²+2

We have to find the product of 3-6y² and y²+2

Clara's Solution:

(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)

                          = 3y² – 12y²

                          = -9y²

NO!

The student's work is INCORRECT!

Clara did not imply the correct distribution of multiplying the terms in the first step.

Here is the correct solution:

(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)

                          = 3y² – 12y² + 6 - 6y⁴

                           = - 6y⁴ - 9y² + 6

Therefore,

(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6

Answer:

-12

Step-by-step explanation:

To decrease by -8 is to subtract, therefore x-8= -20. When you add 8 on both sides, the answer is -12.

Answer:

The domain is -12, 0, 2, 8.

Step-by-step explanation:

The domain is the set of all possible x-values. The x-values are the first numbers in a point.

Step-by-step explanation:

Answer: Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.

Step-by-step explanation:

Given : Rachel has [tex]\dfrac23[/tex] pound of snack mix..

If she ate [tex]\dfrac5{12}[/tex] of the snack mix.

Then, Quantity of snack mix eaten by Rachel = [tex]\dfrac5{12}\times\dfrac23[/tex]

[tex]=\dfrac56\times\dfrac13\\\\=\dfrac{5}{18}[/tex]

Hence, Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.

Answer:

  (b)  13.5

Step-by-step explanation:

The upper vertex would be ...

  3/2(3, 3) = (4.5, 4.5)

and the right vertex would be ...

  3/2(4, 0) = (6, 0).

The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...

  A = (1/2)bh

  A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

Answer:

I'm not sure but I think it is A.

The number of Ava's coins is x. The number of Ava's coins is more than 15. so x is more than 15.

x > 15

Answer:

A

Step-by-step explanation:

Since Ava has more than X coins in her collection then 15 is the amount she used to have so

x> 15
