Tony made 52 decorations for the class party. He made 7 times as many ecorations as Jack did, but he lost 4. Which equation could be used to Find the number of decorations, x, Jack made?

⚫️4x + 7 = 52
⚫️7x + 4 = 52
⚫️4x - 7 = 52
⚫️7x - 4 = 52

Answers

7x-4=52 is correct because he made 7 times more than Jack which is 7x. For example if Jack made 8 decorations, 7 x (8) = 56. If you subtract 4 from 56 you get 52. Therefore, the equation 7x-4=52 is correct.
7x- 4 = 52 is the correct answer.

The area of the first, second, third, and fourth circles will be 56.72 cm², 36.3 ft², 167.33 m², and 188.6 yd² respectively.

What is a circle?

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

Then the radius and diameter are given below.

[tex]\rm r_1 = 4 \dfrac{1}{4} = \dfrac{17}{4} = 4.25 \ cm\\\\\\r_2 = \dfrac{d}{2} = \dfrac{6\frac{4}{5}}{2} = \dfrac{34}{10} = 3.4 \ ft\\\\\\r_3 = \dfrac{d}{2} = \dfrac{14.6}{2} = 7.3 \ m\\\\\\r_4 = 7\dfrac{3}{4} = \dfrac{31}{4} = 7.75 \ yd[/tex]

Then the area of the circle is given as

Area = π × r²

Then the area of the first circle will be

Area = π × r₁²

Area = 3.14 × 4.25²

Area = 56.72 square cm

Then the area of the second circle will be

Area = π × r₂²

Area = 3.14 × 3.4²

Area = 36.3 square ft

Then the area of the third circle will be

Area = π × r₃²

Area = 3.14 × 7.3²

Area = 167.33 square m

Then the area of the fourth circle will be

Area = π × r₁²

Area = 3.14 × 7.75²

Area = 188.6 square yd

Which graft represent -3x+5y=-15

Answers

The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

-3x + 5y = -15

The above function shows a linear function we can write it as:

5y = 3x - 15

y = (3x - 15)/5

If x = 0, y = -3

x = 1, y = -2.4

x = 2, y = -1.8

x = -1, y = -3.6

x = -2, y = -4.2

Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

The dot plots show rainfall totals for several spring storms in highland areas and lowland areas.

What is the range of rainfall for the highland storms?

What is the range of rainfall for the lowland storms?

Answers

Answer:

Part A)  Option c) 15.27 mm

Part B)   Option b) 12.05 mm

Step-by-step explanation:

The mean is also sometimes called the average

To find the mean, you add up every number in the data set, and you divide that sum by the total number of data points within the set.

A) What is the mean rainfall for the highland storms?

The sum of the data of Highlands storms

= 2*2 + 3*4 + 2*6 + 3*8 + 4*10 + 3*12 + 4*14 + 5*16 + 5*18 + 4*20 + 2*22 + 24 + 2*26 + 2*28 + 30 + 32 = 672

the total number of data = 44

Mean = 672/44 = 15.27 mm

So, the answer is option c) 15.27 mm

B) What is the mean rainfall for the lowland storms?

The sum of the data of Lowland storms

= 3*2 + 5*4 + 3*6 + 3*8 + 5*10 + 7*12 + 6*14 + 4*16 +2*18 + 20 + 2*22 + 24 + 2*28 = 530

the total number of data = 44

Mean = 530/44 = 12.05 mm

So, the answer is option b) 12.05 mm
