Answer:

area- 36.07 cm^2

perimeter- 28cm

Step-by-step explanation:

1) we could break the composite shape into 2 seperate shapes:

1 shape- measuring 3.1 by 3.4 cm

2nd shape- measuring (3.1)+(3.8)cm by 3.7 cm

since both shapes are rectangles we can find area by multiplying length and width

so 3.1*3.4=10.54

and 3.1+3.8=6.9

6.9*3.7=25.53

we can add both areas up to get TOTAL area of figure:

25.53+10.54=36.07

area- 36.07 cm

to find perimeter: there are 2 unknown sides in this figure, the bottom side length can be found out by adding 3.1 and 3.8, which is 6.9 and the side adjacent to the bottom one can be found by adding 3.4 and 3.7, which is 7.1

now we add up all the numbers: 3.1+3.4+3.8+3.7+6.9+7.1= 28

Answer:

x = -2/3

Step-by-step explanation:

27^x=1/9

writing 27 as 3^3  and 1/9 as 3 ^-2

3^3^x = 3^-2

We know that a^b^c =a^(b*c)

3^(3x) = 3^-2

Since the bases are the same the exponents need to be the same

3x = -2

x = -2/3

Answer:

~62%

Step-by-step explanation:

Let n(A) be the number of students signed up for Algebra II.

Given that n(A) = 298

Let n(B) be the number of students signed up for Chemistry.

Given that n(B) = 328

n(A [tex]\cup[/tex] B) will be the number of students who have signed up for either one or both of two subjects.

n(A [tex]\cup[/tex] B) = 386

Formula for n(A [tex]\cup[/tex] B):

n(A [tex]\cup[/tex] B) = n(A) + n(B) - n(A [tex]\cap[/tex] B)

Where n(A [tex]\cap[/tex] B) is the number of students signed up for both the courses.

Putting the values in the formula above:

386 = 298 + 328 - n(A [tex]\cap[/tex] B)

n(A [tex]\cap[/tex] B) = 240

Formula for Probability of an event E:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

[tex]P(A \cap B) = \dfrac{n(A \cup B) }{n(A \cap B)}[/tex]

[tex]\Rightarrow P(A \cap B) = \dfrac{240 }{386}\\\Rightarrow P(A \cap B) = 62.17\%[/tex]

Hence, the required probability is ~62%

The probability that a student chosen at random from the 386 will be signed up for both of the courses should be 62%.

Since total of 386 students are taking either one or both of the two courses. If 298 students signed up for Algebra II and 328 have signed up for Chemistry

So here the no of students that signed up for both subjects should be

= 298 + 328 - 386

= 240

Now the probability is

[tex]= 240\div 386[/tex]

= 62%

Hence, The probability that a student chosen at random from the 386 will be signed up for both of the courses should be 62%.

Step-by-step explanation:

Answer:

She needs to order 12 cars

Step-by-step explanation:

To find the total number of models, we just need to multiply the number of options for each choice:

body style: 2 options

interior package: 3 options

drive train: 2 options

So the number of different models is:

2 * 3 * 2 = 12 different models

So in order to have all the possible models, she needs to order 12 cars.

Answer: The equation can be written as 8n = 99.2.

Step-by-step explanation:

In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.

A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.

Hence, the answer can be represented as 8n = 99.2.

Answer:

Area = 370 m²

Cost to paint = £105

Step-by-step explanation:

Area of the wall of a cinema hall = Area of a trapezoid (1)+ Area of a rectangle (2) + Area of a trapezoid (3)

Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

where [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and h is the distance between these sides.

Area of trapezoid (1) = [tex]\frac{1}{2}(11+12)\times 6[/tex]

                                  = 69 m²

Area of the rectangle (2) = Length × Width

                                         = 12 × 15

                                         = 180 m²

Area of the trapezoid (3) = [tex]\frac{1}{2}(12+10)\times 11[/tex]

                                         = 121 m²

Now area of the wall = 69 + 180 + 121

                                   = 370 m²

One tin covers the area = 25 m²

Number of tins required to paint the wall = [tex]\frac{\text{Total area}}{\text{Area covered by one tin}}[/tex]

= [tex]\frac{370}{25}[/tex]

= 14.8

Therefore, number of tins to be purchased = 15

Cost to paint the complete wall = 15 × £7

                                                       = £105

Answer:

$123.45+$36.55

= $160

Step-by-step explanation:

Answer:

Here we have two inequalities.

P is price of the gallon,we have that:

$2.40 ≤ P ≤ $2.65

C is the amount of gallons that Ricardo buys each week.

8,5 ≤ C ≤ 11

Now, with this you can find the maximum and minimum amount that he can spend on a week.

The minimum is when he buys only 8.5 gallons and the price per gallon is $2.40

Cost = 8.5*$2.40 = $20.4

The maximum cost is when he buys 11 gallons, and the price of the gallon is $2.65

Cost = 11*$2.65 = $29.15

So the amount that he spends per week in gas, S, is:

$20.4 ≤ S ≤  $29.15

The scale factor for the given dilation is 3

Dilation is a transformation of an object which changes its size. if the dilated image is larger then it is called enlargement. If the dilated image is smaller it is called reduction.

If the dilation has the origin as the center of dilation, we can find points on the image formed by dilation by multiplying the coordinates of the original geometric object like triangle multiplying by the scale factor. For scale factor k, the transformation of the dilation is written as :  (x, y) → (k x, k y).

The scale factor ,k  = coordinate of image / coordinate of original

Given that Triangle ABC is dilated to create triangle A’B’C’ using point O as the center of dilation as shown in the figure

Scale Factor = coordinate of image / coordinate of original

                    = OA' / OA = 9/3 = 3

Therefore, the scale factor for the given dilation is 3.
