Set up a proportion.
What is h?

Step-by-step explanation:

Write the system of equations as an augmented matrix. Then solve for x and y.

3x+y=-11

-9x-3y=33

Question:

What’s the volume ?

Answer:

Volume: 8663.2

Area : 392

Step-by-step explanation:

The formula for volume is length times width times height (L x W x H)

So

28 x 28 = 784 x 22.1 = 17326.4 (Crazy right) But this is not the answer. A triangle is half of a Square so we divde by 2

17326.4 / 2 = 8663.2

The Volume is 8663.2

And if you are looking for the Area it's 392

Answer:

The value of x is 21 .

Step-by-step explanation:

We are given that x varies directly as y

--- A

We are given that x = 7 and y = 28

Substitute the values in A

7 = 28k

Now equations becomes :  

y = 84

Hence The value of x is 21 .

Find the value of y for a given value of x, if y varies directly with x.

If y = −252 when x = 84, what is y when x = 74

Step-by-step explanation:

Answer:

3.

Step-by-step explanation:

3(n + 4) = 21

3n + 12 = 21

3n = 21 - 12 = 9

n = 3.

Answer:

n = 3

Step-by-step explanation:

Given

3(n + 4) = 21 ( divide both sides by 3 )

n + 4 = 7 ( subtract 4 from both sides )

n = 3

Answer:

Curved Surface Area = 48π cm² (≈ 150.72 cm²)

Total Surface Area = 120π cm² (≈ 376.8 cm²)

Step-by-step explanation:

GIVEN :-

TO FIND :-

GENERAL FORMULAES TO BE USED IN THIS QUESTION :-

Curved Surface Area of cylinder = 2πrh

Total surface Area of cylinder = 2πrh + 2πr² = 2πr(h + r)

SOLUTION :-

Curved Surface Area of cylinder = 2×π×6×4 = 48π cm² ≈ 150.72 cm²

Total Surface Area of cylinder = 2×π×6(4 + 6) = 120π cm² ≈ 376.8 cm²

Answer:

C.372

Step-by-step explanation:

A prism is a three dimensional shape with two identical shapes facing each other known as bases.

A triangular prism has two triangular bases and three rectangle.

From the net attached:

Area of triangle 1 = area of triangle 2 = (1/2) * base * height = (1/2) * 10 cm * 12  cm = 60 cm²

Area of rectangle 1 = Area of rectangle 2 = length * width = 13 cm * 7 cm = 91 cm²

Area of rectangle 3 = base * height = 10 cm * 7 cm = 70 cm²

Total surface area = Area of triangle 1 + Area of triangle 2 + Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Total surface area = 60 + 60 + 91 + 91 + 70 = 372 cm²

Answer:

the total payment need to pay is $525

Step-by-step explanation:

Given that

The amount at promissory note issued is $500

The rate of interest is 10%

And, the time period is 180 days

So, the total payment included is

= $500 + ($500 × 10% × 180 days ÷ 360 days)

= $500 + $25

= $525

hence, the total payment need to pay is $525

Step-by-step explanation:

Answer:

9.42 m

6.28m

Step-by-step explanation:

to determine the distance walked, calculate the circumference of the circular pool

circumference of a circle = πD

π = 3.14

D = diameter

3 x 3.14 = 9.42 m

Difference in circumference =  π( diameter of bigger circle - diameter of smaller circle)  

diameter of smaller circle = 5 x 2 = 10

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x ( 12 - 10) = 6.28

Answer:

x ≤ -3 ∨ x ≥ 0

Step-by-step explanation:

3+ 2x ≥ 0

2x ≥ -3

x ≥ -3/2

if x ≥ -3/2

-2x - 3 + 1 ≤ -2

-2x ≤ 0

x ≥ 0

if x ≤ -3/2

2x + 3 + 1 ≤ -2

2x ≤ -6

x ≤ -3

x ≤ -3 ∨ x ≥ 0

Answer:

V = 7,600.17

Step-by-step explanation:

Given:

V=25000(0.82)^t

Where,

V = value of the car

t = time in years

Find V when t = 6

V = 25,000(0.82)^t

= 25,000(0.82)^6

= 25,000(0.304006671424)

= 7,600.1667856

Approximately

V = 7,600.17
