Answer:

4.5 inches

Step-by-step explanation:

Use the formula for the surface area of a sphere, SA = 4[tex]\pi[/tex]r²

Plug in the surface area and solve for r, the radius:

SA = 4[tex]\pi[/tex]r²

254.5 = [tex]\pi[/tex]r²

20.25 = r²

4.5 = r

So, the radius is approximately 4.5 inches

Answer:

x=10 and x=-6

Step-by-step explanation:

f(x)=(x-2)²-64 (Given)

0=(x-2)²-64 (Set equation equal to 0)

64=(x-2)² (Add 64 to both sides)

±8=x-2 (Take the square root of both sides)

Because there are two possible roots, make 2 equations to find both:

8=x-2 and -8=x-2

10=x and -6=x

Step-by-step explanation:

From Pythagorean theorem

x^2 = (10)^2 - (8)^2 = 36 or x =6

sin theta = opp/hyp = 6/10 = 3/5

cos theta = adj/hyp = 8/10 = 4/5

tan theta = opp/adj = 6/8 = 3/4

cot theta = 1/tan theta = 4/3

sec theta = 1/cos theta = 5/4

csc theta = 1/sin theta = 5/3

Answer:

7/4 = 35/20

Step-by-step explanation:

35 = 7 x 5 ; 20 = 4 x 5

Answer:

x = 23

Step-by-step explanation:

Remember, angles in a triangle add up to equal 180

That being said we can create an equation to solve for x

180 = 110 + 35 + x + 12

now we solve for x

step 1: combine like terms

110 + 35 + 12 = 157

now we have 180 = 157 + x

step 2 subtract 157 from each side

180 - 157 = 23

157  - 157 cancels out

we're left with x = 23

The value of x will be 60.33. Then the tan 48° will be 67 / 60.33.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The right-angle triangle has angles of 48°, 42°, and 90°.

Then the value of x will be

tan 42° = x / 67

         x = 60.33

Then the tan 48° is given as

tan 48° = 67 / 60.33

Answer: 35 trading cards

Step-by-step explanation:

Assume the trading cards collected by Trey is x.

That means that the number of trading cards collected by Abigail is 7x.

Relevant expression is:

7x + x = 40

8x = 40

x = 40/8

x = 5 trading cards

This means that Trey collected 5 trading cards

Abigail collected 7 times that figure so Abigail collected:

= 7 * 5

= 35 trading cards

The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0). Option C is correct.

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

The general parabola equation is as follows: y=p (x-h)²+k or x=p(y-k)²+h, with (h,k) indicating the vertex.

The equation of the parabola is;

y=p (x-3)²+0

y=p(y-0)²+ (-4)

On combining both the equations;

f(x) = 8 (x-3) (x+4)

The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0).

Hence,option C is correct.

Answer:

692 ft^2

Step-by-step explanation:

Area of a circle = (pi)(radius)^2

Here,

Area of the circle = (3.14)(21 ft)^2 = 1385 ft^2

Area of half this circle = area of the semicircle = 1385 ft^2  /  2, or

Area of semicircle = 692 ft^2

Answer:

Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.

Step-by-step explanation:

From. The plot given :

We could approximate the proportion of females older than 60 as follows _

COUNTRY A :

60 - 69 = 0.105

70 - 79 = 0.065

80 - 89 = 0.038

90+ = 0.01

Total = About 0.218

COUNTRY B :

60 - 69 = 0.14

70 - 79 = 0.11

80 - 89 = 0.07

90+ = 0.02

Total = About 0.34

From the estimated proportion, the proportion of females on country B is more than the proportion in country A.

Answer:

Commitment Adherence Percentage = 81.[tex]\overline{81}[/tex]%

Step-by-step explanation:

The time period Amy scheduled herself, t = 8 a.m. - 1 p.m. from Sunday through Wednesday

The period she released her interval = 11 a. m. - 1 p.m.

Commitment Adherence Percentage = Service Minutes/(Posted Minutes + Released Lockdown Minutes) × 100

Posted minutes = 5 hours/day × 60 minutes ×  4 days = 1200 minutes

Serviced minute = 5 hours/day × 60 minutes ×  3 days + 3 hours × 60 minutes/hour = 1,080 minutes

Released minutes = 2 hours × 60 minutes/hour = 120 minutes

Commitment Adherence Percentage = (1,080/(1,200 + 120)) × 100 = 81.[tex]\overline{81}[/tex]%
