Answer:

532 m ^2

Step-by-step explanation:

18x18 + 1/2x8x 16 + 1/2 x 16 x18

324 + 64+ 144 = 532

Answer:

B) 39/89

Step-by-step explanation:

With reference angle E

hypotenuse (h) = 89

base (b) = 39

cosine angle E

= b /h

= 39/89

Speed  = 93km /h  and  72km/h

Answer: The taxi went a distance of 554.7km

Step-by-step explanation:

Speed  = Distance / Time

Distance covered in the first trip = Speed x Time

Time = 1 hour 54 min =1+0.9 hours  =1.9hours

=93km / h x 1.9 hours =176.7km

Distance covered in the second  trip = Speed x Time

Time = 5 hours 15min = 5+0.25hours  =5.25hours

=72km / h x 5.25hours =378 km

Total distance =176.7km+378 km

=554.7km

To find the area of a circle we have [tex]\pir^{2}[/tex] and the radius is half of the diameter so we have 4.5² which gives 16.25π

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

[tex] {x }^{2} - 3x + 4(x - 3)[/tex]

2) Expand by distributing terms.

[tex] {x}^{2} - 3x + 4x - 12[/tex]

3) Collect like terms.

[tex] {x}^{2} + ( - 3x + 4x) - 12[/tex]

4) Simplify.

[tex] {x}^{2} + x - 12[/tex]

The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

Step-by-step explanation:

Volume of a cylinder is [tex]\pi r^{2}h[/tex]

So solve both cylinders to get

13571.68

Subtract to get the difference

6785.84

The location of each angle make them vertical angles. For the lines to be parallel the two angles need to be equal to each other.

5x + 20 = 3x + 60

Subtract 3x from both sides:

2x + 20 = 60

Subtract 20 from both sides:

2x = 40

Divide both sides by 2:

X = 20

Answer:

8 and 36

Step-by-step explanation:

let the daughter's age be x then father is x + 28

In 6 years their ages are

x + 6 and x + 28 + 6 = x + 34

Father is 3 times her age , then equation is

x + 34 = 3(x + 6) ← distribute

x + 34 = 3x + 18 ( subtract x from both sides )

34 = 2x + 18 ( subtract 18 from both sides )

16 = 2x ( divide both sides by 2 )

8 = x

Daughter's age is 8 and father's age is 8 + 28 = 36

Answer:

600

Step-by-step explanation:

? = 1000 x .03 x 20

the 1000 is the original amount

the .03 is the percent/interest

the 20 is the time

Answer:

80 + 15x ≤ 300

Step-by-step explanation:

max amount = $300

already spent = $80

$300 - 80 = $220

shirts = $15 each

80 + 15x ≤ 300

$80 that is already spent + $15x ≤ $300 maximum

x = number of shirts

The Volume of pyramid is 19.5 [tex]m^{3}[/tex].

A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apx. Each base edge and apx form a triangle, called a lateral face.

The volume of a pyramid refers to the space enclosed between its faces.

Volume of pyramid = (1/3) (Base area * height of pyramid )

According to the question

Area of the base = 6.8 [tex]m^{2}[/tex]

Height of the pyramid = 8.6 m

now,

using the formula of Volume of pyramid

Volume of pyramid = (1/3) (Base area * height of pyramid )

substituting the values

Volume of pyramid = (1/3) ( 6.8 * 8.6 )

                                 = 19.49 [tex]m^{3}[/tex]

Rounding off to  nearest tenth of a cubic meter

Volume of pyramid = 19.5 [tex]m^{3}[/tex]

Hence, the Volume of pyramid is 19.5 [tex]m^{3}[/tex]

Answer:

  100

Step-by-step explanation:

A root is equivalent to a fractional power. A square root is a 1/2 power. A cube root is a 1/3 power. The index of the root is the denominator of the fraction.

Of course the usual rules of exponents apply in evaluating an expression.

  (a^b)^c = a^(bc)

Your expression can be simplified as follows.

  [tex]\displaystyle\sqrt[3]{1000^2}=(1000^2)^{\frac{1}{3}}=1000^{\frac{2}{3}}=(10^3)^{\frac{2}{3}}=10^2=\boxed{100}[/tex]

It can also be simplified another way:

  [tex]\displaystyle\sqrt[3]{1000^2}=\sqrt[3]{(10^3)^2}=\sqrt[3]{(10^2)^3}=10^2=100[/tex]

a. circle with center at (–5, 10), shading inside the circle

Step-by-step explanation:

I have a quizlet for those towards the end of the course aka Cameron its

HELI KADAKIA to study ofc

The graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The given equation of the graph is f(x + 5)² + (y – 10)² < 169. When we plot the equation we get the circle having an inside shaded part. The coordinates of the circle are (5,-10).

Therefore, the graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
