Answer:

77 cm²

Step-by-step explanation:

We know that

Area of trapezium = ½ (a + b) × h

Area = ½ × (10 + 12) × 7

Area = ½ × 22 × 7

Area = 11 × 7

Area = 77 cm²

Length of parallel sides = 10 cm and 12 cm

Height = 7 cm

Area of trapezium

[tex]\begin{gathered} {\underline{\boxed{ \rm {\red{Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: (a \: + \: b) \: \times \:Height }}}}}\end{gathered}[/tex]

Where ,

[tex] \begin{cases} \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: (10 \: + \: 12) \: \times \:7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: 22\: \times \:7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \: \frac{1}{ \cancel2} \: \times \: \cancel{22} \: ^{11} \: \times \:7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \:11 \: \times \: 7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \:77 \: {cm}^{2} \end{cases}[/tex]

[tex]\\ \sf\longmapsto \dfrac{4x+2}{x-9}=\dfrac{3}{5}[/tex]

[tex]\\ \sf\longmapsto 5(4x+2)=3(x-9)[/tex]

[tex]\\ \sf\longmapsto 20x+10=3x-27[/tex]

[tex]\\ \sf\longmapsto 20x-3x=-27-10[/tex]

[tex]\\ \sf\longmapsto 17x=-37[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{-37}{17}[/tex]

Answer:

[tex]\frac{4x+2}{x-9}[/tex] = [tex]\frac{3}{5}[/tex]

5( 4x+ 2 ) = 3 ( x-9 )

20x + 10 = 3x - 27

20x -3x = -27 -10

17x = -37

x = - 37/17

Answer:

The equation is following the mathematical rule of multiplying exponents.

Step-by-step explanation:

As an example to back up the answer, when you have half of a dollar, that is $0.50, if you took a half (1/2) of $0.50 that would be one fourth (1/4) of a dollar, but half of 50 cents ($0.50) A similar thing is happening with this problem. When you have two numbers (2 and 4) when you multiply them together, they equal to eight (8) for this problem, when you multiply two exponents together, you are raising the coefficient (a real number like 6) to the power of 2, and then taking that number and multiplying it by the power of 4. This is similar to the half of 50 cents, is equal to 1/4 of dollar  ($0.25)

Hope this helps explain multiplying exponents together, and the mathematical rule behind it.

by using the formula, we can find :

T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =

(2401 - 2058 + 1127 - 126 +24) / 24 =

1368/ 24 = 57

T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =

Answer:2500 cubic meters (m^3)

Step-by-step explanation:

To find the volume of a rectangular prism (like a pool), use the formula

V = l * w * h

V = 50 * 25 * 2

V = 2500

Hi there!

h(x) = 5x + 11

To find h(7) - 3, we can substitute 7 for x and subtract 3:

h(7) = 5(7) + 11 - 3

Simplify:

h(7) = 35 + 11 - 3

h(7) = 43

h(x) = 5x + 11

h(7) = 5 · 7 + 11 = 35 + 11 = 46

h(7) - 3 = 46 - 3 = 43 ← the end answer

Answer:

y+11=28

subtract 11 from both sides of equation

you are left with y= on left side and on right side you are left with 17

Answer:

11

Step-by-step explanation:

y + 11 = 28, subtract 11 from both sides because whatever you do to one side, you have to do to the other.

The time that the ball is at its maximum height approximate will be 3.5 seconds, the time that the ball hits the ground will be 5 seconds, approximately, and the time is the ball 67 feet above the ground will be 2 and 4 seconds.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

A baseball is hit upward from a height of 3 feet with an initial velocity of 80 feet per second (about 55 mph). The graph shows the height of the ball at any given second during its flight.

From the graph, the time that the ball is at its maximum height approximate will be 3.5 seconds.

The time that the ball hits the ground will be 5 seconds, approximately.

The time is the ball 67 feet above the ground will be 2 and 4 seconds.

The complete question is attached below.

Answer:

angle C = 78

angle D = 108

Step-by-step explanation:

the measure of angle A is 102

To find the measure of angle C

let Angle C be x

102 + x = 180 (linear pair)

x = 180 -102

x = 78

angle C = 78

angle B = 78 (vertically opposite angles are equal)

angle D = 108 (vertically opposite angles are equal)

it is less than square root 30

Answer:

supplement = 152°

Step-by-step explanation:

If the complement is 62° , then

angle = 90° - 62° = 28° ( Complementary angles sum to 90° )

Supplementary angles sum to 180° , then supplement of 28° is

180° - 28° = 152°

The answer to the proportion is 8

The cost of tiles per square meter is an illustration of unit rates. If the area of the tiles is 17m^2, the cost of tiles per square metre is R5.00 per square metre.

Given that:

[tex]Cost = R85.00[/tex]

The unit cost (i.e. cost of tiles per square metre) is calculated as:

[tex]Unit =\frac{Cost}{Area}[/tex]

Where:

[tex]Cost = R85.00[/tex]

[tex]Area \to[/tex] Area of the tiles

The dimension of a tile is not given. So, I will use an assumed value.

Assume the tile has an area of 17m^2.

So, the unit cost is:

[tex]Unit = \frac{85.00}{17}[/tex]

[tex]Unit = 5[/tex]

Hence, if the area of the tiles is 17m^2, the cost of tiles per square metre is R5.00 per square metre.

Answer:

g=5

Step-by-step explanation:

6.3g + 8 = 2.3g + 28

Subtract 2.3g from each side

6.3g-2.3g + 8 = 2.3g-2.3g + 28

4g +8 = 28

Subtract 8 from each side

4g+8-8= 28-8

4g = 20

Divide by 4

4g/4 = 20/4

g = 5

Answer:

g = 5

Step-by-step explanation:

6.3g + 8 = 2.3g + 28

Subtract 2.3g from each side

6.3g-2.3g + 8 = 2.3g-2.3g + 28

4g +8 = 28

Subtract 8 from each side

4g+8-8= 28-8

4g = 20

Divide by 4

4g/4 = 20/4

g = 5

Answer:

Step-by-step explanation:

-1.

Step-by-step explanation:

Note: 10 = 10^1 so:

10^-3 x 10 x 10^k = 10^(-3 + 1 + k) = 10^(k - 2).

So 10^(k - 2) = 10 ^(-3)

and k - 2 = -3

k = 2 - 3 = -1.
