Find the area of the figure.

Step-by-step explanation:

Number of students in class = 90

ratio of boys and girls = 4:5

sum of ratios = 9

Number of boys = 4/9 × 90

= 360/9

= 40

Number of girls = 5/9 × 90

= 450/9

= 50

As Per Provided Information

Dimensions of rectangle prism are 3 cm , 4 cm and 10 cm .

We have been asked to determine it's surface area.

[tex] \underline{\boxed{\bf \: Surface \: Area_{(Rectangular \: Prism)} = 2(lw + hl + hw}}[/tex]

where,

w denote width

h denote height

l denote length

[tex] \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \: 2(3 \times 4 + 4 \times 10 + 10 \times 3) \\ \\ \\ \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \:2(12 + 40 + 30) \\ \\ \\ \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \:2(82) \\ \\ \\ \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \:164 \: {cm}^{2} [/tex]

Therefore,

Answer:

Surface area of rectangular prism is 164cm²

Step-by-step explanation:

Given :-

To find:-

Solution:-

Surface area of rectangular prism :-

2(lb + bh + hl)

putting the known values ,

Surface Area = 2(3×4+4×10+10×3) cm²

Surface area = 2(12+40+30) cm³

Surface area = 164cm²

Answer:

D and B

Step-by-step explanation:

Because D is saying the negative number is less than, we know it is true.

Because B states that -7.1 is more, it is correct. -7.1 is closer to zero than -7.8, making it a larger number.

Answer:

B. -7.1 > -7.8

D. -6[tex]\frac{3}{5}[/tex] < 6[tex]\frac{2}{5}[/tex]

Answer:

126

Step-by-step explanation:

In math, "of" usually means multiplication.

9/13 of 182 means 9/13 × 182.

9/13 × 182 = 9/13 × 182/1 = (9 × 182)/(13 × 1) = 1638/13 = 126

Answer: 126

Answer:

126

Step-by-step explanation:

To find 9/13 of 182, we would divide 182 by 13 and multiply the quotient by 9.

182 ÷ 13 = 14

14 • 9 = 126

To double-check our answer, we can divide 126 by 182 and see if the fraction is congruent to 9/13.

126 ÷ 182 = 0.6923

9 ÷ 13 = 0.6923

Step-by-step explanation:

Step-by-step explanation:

A = 1/2*h(base + base)

Plugging everything in gives you:

1/2*(6.8)(7.5 + 13.7 + 5.3)

((13.7 + 5.3) gives you the bottom base)

First, adding inside the parentheses:

1/2*(6.8)(26.5)

Multiply 6.8 by 26.5(h times bases):

1/2*(180.2)

Lastly, multiply:

A= 90.1 m^2

Answer: C

Step-by-step explanation: The answer is C because unbending suing distributive property, the equation becomes (7 x 2) + (7 x 3). Solving for these parentheses, the equation becomes 14 + 21. I hope this helps!

Answer:

40π m² and 125.6 m²

Step-by-step explanation:

the area (A)  of the sidewalk is calculated as

A = outer area - inner area

(a)

A   = πr₁² - πr₂² ( r₁ is radius of outer circle and r₂ the radius of inner circle )

A  = π × 11² - π × 9²

  = 121π - 81π

 = 40π m²

(b)

A = 40 × 3.14 = 125.6 m²

Answer:

A and B

Step-by-step explanation:

See explanation below

The given series  40 + 20 + 10 + 5 is a geometric series.

The geometric series the ratio of consecutive terms is equal and the ratio is called the common ratio of the geometric series.

Let us find the ratio of consecutive terms of each of the given series.

For the series 40 + 50 + 60 + 70

50/40 = 5/4

60/50 = 6/5

Since, 5/4 ≠ 6/5 hence, it is not a geometric series.

For the series 40 + 42 + 44 + 46

42/40 = 21/10

44/42 = 22/21

Since, 21/10 ≠ 22/21 hence, it is not a geometric series.

For the series 40 + 80 + 40 + 120

80/40 = 2

40/80 = 1/2

Since, 2 ≠ 1/2 hence, it is not a geometric series.

For the series 40 + 20 + 10 + 5

20/40 = 1/2

10/20 = 1/2

Since, 1/2 = 1/2 hence, it is a geometric series.

Therefore, D is the correct option.

[tex]y=\frac{1}{4} x+3[/tex]

Step-by-step explanation:

[tex]y-5=\frac{1}{4} (x-8)[/tex]

Answer:

y = [tex]\frac{1}{4}[/tex] x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = [tex]\frac{1}{4}[/tex] , then

y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

to find c substitute (8, 5 ) into the partial equation

5 = 2 + c ⇒ c = 5 - 2 = 3

y = [tex]\frac{1}{4}[/tex] x + 3 ← equation of line

Launching the fuse is an illustration of a quadratic model, and the equation of the quadratic model is f(x) = 15(x - 3)(x - 8)

From the complete question, the zeros of the quadratic function are:

x = 3 and x = 8

Rewrite as:

x - 3 = 0 and x - 8 = 0

So, the quadratic equation is:

f(x) = a(x - 3)(x - 8)

Also from the graph, we have the following point

(x,y) = (4,60)

Substitute 4 for x and 60 for f(x) in the function

a(4 - 3)(4 - 8) = 60

Evaluate the difference

a(1)(-4) = 60

Evaluate the product

-4a = 60

Divide both sides by 4

a = -15

Substitute a = -15 in f(x) = a(x - 3)(x - 8)

f(x) = -15(x - 3)(x - 8)

Hence, the equation of the quadratic model is f(x) = 15(x - 3)(x - 8)
