Round 249798.828806 to the nearest ten.

Answer:

16 people haven't replied

Step-by-step explanation:

Add 9 + 8 = 17 and subtract 33 - 17 = 16

If this helps

The guests (g) still need to reply are 16.

Arithmetic operation is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Now it is given that,

Number of guests invited = 33

Number of guests replied "will attend" = 8

Number of guests replied "will not attend" = 9

So, total guest replied = 8 + 9

⇒ total guest replied = 17

Thus, the guests (g) still need to reply = 33 - 17

⇒ the guests (g) still need to reply = 16

Thus, the guests (g) still need to reply are 16.

Answer:

[tex]\frac{55}{14}[/tex]

Step-by-step explanation:

First, we convert the mixed numbers into improper fractions: [tex]1\frac{3}{7} =\frac{10}{7}[/tex], and [tex]2\frac{3}{4}=\frac{11}{4}[/tex]. Now, we multiply the fraction using the multiplication rule, [tex]\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}[/tex]: [tex]\frac{10}{7} \times \frac{11}{4} = \frac{110}{28} = \frac{55}{14}[/tex].

Thus, the product of the two given fractions is 55/14.

Answer:

Veronica left a tip of  $6.87

Step-by-step explanation:

3.50×2= 7

6.95×2= 13.9

7.95+12.95+15.95+7+13.9 = 41.8

0.25×41.8= 10.45

41.8-10.45= 31.35

0.0925×31.35 = 3

31.35+3 = 34.35

0.20×34.35 = 6.87

Answer:

Step-by-step explanation:

(x⁴ -11x² + 30)(x +2) = (x⁴ -11x² + 30)*x + (x⁴ -11x² + 30)*2

                               = x⁴*x - 11x²*x + 30*x + x⁴*2 - 11x²*2 + 30*2

                               =x⁵ - 11x³ + 30x + 2x⁴ - 22x² + 60

                               = x⁵ + 2x⁴ - 11x³ - 22x² + 30x + 60

Answer:

Step-by-step explanation:

(g∘f)(4) = g(f(4))

= g(-4³)

= g(-64)

= | ⅛(-64)-1 |

= | -8-1 |

= 9

The value of (g · f)(4) is found to be 9.

A function is a kind of relation in which the domain(x) has one and only one image in the range(y).

A composite function is a kind of function that combines two functions in the order in which it is written.

(g ·f)(x) = g(f(x))

We have to f(4) and substitute that g(x).

f(x) = -x³

f(4) = -64

[tex]g(x) = \left| \frac{1}{8} x-1 \right|\\\Rightarrow g(f(x))= \left| \frac{-64}{8}-1 \right|\\=\left| -8-1 \right|\\=\left| -9\right|\\=9[/tex]

Thus, we have found the value of (g · f)(4) to be 9. The correct answer is option C.

So the formula of area of the circle A=πr2. The answer is 153.86.

Step-by-step explanation:

You first divide 14/2=7 then do 7^2 which equals 49 lastly multiplying 3.14 X 49. So how is the radius 7 because half of a diameter is a radius.Therfore the answer is 153.86.

Step-by-step explanation:

yx = 2

if x = 7

y(7) = 2

y = 2/7

yx = 2

if y = 2

2(x) = 2

x = 1

Answer:

The height of the tree is approximately 21.4 feet

Step-by-step explanation:

We list out the question parameters first as follows;

The distance from the base of the tree where the angle of elevation is measured, d = 10 feet

The angle of elevation to the top of the tree from 10 feet from the base, θ = 65°

Let 'h' represent the height of the tree, then we have;

The line formed by the angle 65° angle, the height of the tree, 'h', and the distance 'd', form a right triangle with 'h' being the opposite leg to the given reference angle, 65°, and 'd' being the adjacent leg

By trigonometric ratio, we have;

[tex]tan(\theta) = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length} = \dfrac{h}{d}[/tex]

∴ h = d × tan(θ)

Plugging in the given values, we get;

h = 10 feet × tan(65°) = 21 feet [tex]5\frac{11}{32}[/tex] inches

∴  By rounding to the nearest tenth of a foot, the height of the tree, h ≈ 21.4 feet.
