Area:

Answer:

80in²

Step-by-step explanation:

Hey There!

So the first step of this problem is to find the width of the scale drawing

To do so we need to find the scale factor

To find the scale factor we divide the length of the room by the length of the scale factor

32/8=4

so the scale factor is 4

now to find the width

40/4=10

so the width of the scale drawing is 10 in

now we can find the area given the length and the width

10x8=80in²

so we can conclude that the area of the scale drawing is 80in²

Answer: P(x)=  x³ - 3 x² - 46 x +168

Step-by-step explanation:

(4,6, -7)

hence the polynomial will be equal to

P(x) = (x-4) (x-6) (x+7)

P(x) = (x-4) (x²+7 x -6 x -42)

P(x) = (x-4) (x²+x -42)

P(x) = x³ + x²-42 x -4 x² -4 x +168

P(x) =  x³ - 3 x² - 46 x +168

hence, the required polynomial is P(x) =  x³ - 3 x² - 46 x +168

Answer:

[tex]Ratio = 3: 2[/tex]

Step-by-step explanation:

Given

Shape: Cube

[tex]L = 8cm[/tex]

The surface area is calculated as:

[tex]Area = 6*L^2[/tex]

[tex]A_1 = 6*8^2[/tex]

[tex]A_1 = 384[/tex]

When it is cut by half; the length is affected; so, it forms a cuboid of the following dimension:

[tex]L = \frac{8}{2} = 4[/tex] --- Length

[tex]W = 8cm[/tex] --- Width

[tex]H = 8cm[/tex] --- Height

The surface area is:

[tex]Area = 2 *(L*W + H * L + W * H)[/tex]

[tex]A_2 = 2 *(4*8 + 8 *4 + 8 * 8)[/tex]

[tex]A_2 = 2 *128[/tex]

[tex]A_2 = 256[/tex]

So, the ratio of surface area is:

[tex]Ratio = A_1 : A_2[/tex]

[tex]Ratio = 384 : 256[/tex]

Divide by 128

[tex]Ratio = 384/128 : 256/128[/tex]

[tex]Ratio = 3: 2[/tex]

Answer:

We reject the null hypothesis, and accept the alternative hypothesis.

So, it means that the machine is under filling the bags

Step-by-step explanation:

Given

Null Hypothesis

[tex]H_0:\mu = 419[/tex] --- works correctly at 419g

Alternate Hypothesis

[tex]H_0:\mu < 419[/tex] --- under fills the bag

[tex]n =15[/tex] --- the sample

[tex]\bar x = 409[/tex] --- the mean

[tex]\sigma = 22[/tex] --- the standard deviation

[tex]\alpha = 0.05[/tex] --- the significance level

Required

What is the decision rule

Since n is less than 30, we make use of t test

[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]

[tex]t = \frac{409 - 419}{22/\sqrt{15}}[/tex]

[tex]t = \frac{-10}{22/ 3.87}[/tex]

[tex]t = \frac{-10}{5.58}[/tex]

[tex]t = -1.792[/tex]

Calculate df

[tex]df = n-1[/tex]

[tex]df = 15-1[/tex]

[tex]df = 14[/tex]

Calculate the p value from the Student's t-distribution  at df = 14 and [tex]t = -1.792[/tex]

[tex]p =0.047[/tex]  

Given that: [tex]\alpha = 0.05[/tex]

Since [tex]p < \alpha[/tex]

So, it means that the machine is under filling the bags

Answer:

$229.73

Step-by-step explanation:

5 Pair of jeans = 127.63

divide by 5 to get 1 pair of jeans.

1 pair of jeans = 25. 526 rounded 25.53

times 9 to get to 9 pair of jeans.

9 pair of jeans = 229. 734 rounded 229.73

Step-by-step explanation:

Answer:

£9.80

Step-by-step explanation:

The computation of the total value is shown below:

Given that

The value of 20p coins is £2.80

So the value of 50p would be

= £2.80 × 50 ÷ 20

= £7

Now the total value is

= £2.80 +  £7

= £9.80

Answer:

382 cm²

Step-by-step explanation:

The shape can be decomposed into two rectangular prism or cuboids

✔️Dimension of prism 1 (smaller prism):

L = 10 cm

W = 3 cm

H = 7 - 4 = 3 cm

Surface area of prism 1 = 2(LW + LH + WH)

= 2(10*3 + 10*3 + 3*3)

= 2(69)

Surface area of prism 1 = 138 cm²

✔️Dimension of prism 2 (larger prism):

L = 10 cm

W = 8 cm

H = 4 cm

Surface area of prism = 2(LW + LH + WH)

= 2(10*8 + 10*4 + 8*4)

= 2(152)

Surface area of prism 2 = 304 cm²

✅Surface Area of the composite shape = (Surface area of prism 1 + surface area of prism 2) - (2 × area of the base of prism 1)

= (138 + 304) - (2 × L × W)

= 442 - (2 × 10 × 3)

= 442 - 60

= 382 cm²

Answer:

  (c)  180 cm²

Step-by-step explanation:

Maybe you want the area of the trapezoid. That is given by the formula ...

  A = (1/2)(b1 +b2)h

where b1 and b2 are the base lengths, and h is the height.

Here, the top base is marked 16 cm, and the bottom base is shown as 4 cm longer, so is 20 cm.

  A = (1/2)(16 cm +20 cm)(10 cm) = 180 cm²
