Answer:

47%

Step-by-step explanation:

find the total tablets

44 + 94 + 62 = 200

number of tablets = 94

94 / 200 = 0.47

0.47 x 100 = 47%

If angle BOC in circle is 68° then the measure of angle BAC is 34°.

Given that angle BOC in the circle is 68°.

We have to find the angle BAC.

We have that m∠BOC=arc BC ------by central angle.

we have m∠BOC=68°.

therefore arc BC=68°.

We know that the inscribed angle is half that of the arc it comprises so m∠BAC=1/2 *(arc BC)-----1

In geometry one of the theorem states states that angle at the center of a circle is twice angle at the circumference.

We have that arc BC=68°

substitute arc BC in equation 1 to get the measurement of ∠BAC.

m∠BAC=[tex]68/2[/tex]

=34°

Hence if angle BOC in circle is 68° then the measure of angle BAC is 34°.

Answer:

blank area = 1.5π units²

Step-by-step explanation:

area of full circle = πr² = π6² = 36π units²

blank area = (15/360)(36π) = 1.5π units²

The area blank in a circular mosaic pattern is 4.71 square units.

A circle is a collection of all points in a plane which are at a constant distance from a fixed point. A circle is a round-shaped figure that has no corners or edges.

For the given situation,

The diagram shows the circle with a central angle cutout.

The central angle, θ = 15°

Radius of the circle, r = 6 units

The formula of area blank in circle is

[tex]Area_{blank} = \frac{\theta}{360}\pi r^{2}[/tex]

⇒ [tex]Area_{blank} = \frac{15}{360}(3.14) (6)^{2}[/tex]                [∵ π = 3.14 ]

⇒ [tex]Area_{blank} = 0.0416(3.14) (36)[/tex]

⇒ [tex]Area_{blank} = 4.71[/tex]

Hence we can conclude that the area blank in a circular mosaic pattern is 4.71 square units.

Answer:

The intersections of a transversal with two lines create various types of pairs of angles: consecutive interior angles, consecutive exterior angles, corresponding angles, and alternate angles.

Answer:

The correct answer is option C.

Step-by-step explanation:

To find a substitute for the variable y in the second equation, you need to first find out what y is equivalent to in the first equation: in other words, isolate the variable. [tex]2y-x=6[/tex] ⇒ [tex]2y = x + 6[/tex] ⇒ [tex]y = 0.5x + 3[/tex]. Since y is equivalent to [tex]0.5x+3[/tex] in the first equation, that means you can use that to replace y in the second equation, so the correct choice is C.

y varies as √(x+5)

Step-by-step explanation:

y varies as √(x+5)

y= k√(x+5)

k is a constant connecting the two sides.

therefore

k=y/√(x+5)

k=4/√(-1+5)

k= 4/√4

k=4/2

k=2

Y when x=11

y=k√(x+5)

y=2√(11+5)

y=2√16

Answer:

Wood needed to build deck = 442.86 feet² (Approx.)

Step-by-step explanation:

Given:

Diameter of pool = 16 feet

Dimensions of rectangular deck = 28 feet by 23 feet

Find:

Wood needed to build deck

Computation:

Radius of pool = Diameter of pool / 2

Radius of pool = 16 / 2 = 8 feet

Wood needed to build deck = Area of rectangle deck - Area of circular pool

Wood needed to build deck = [l x b] - πr²

Wood needed to build deck = [28 x 23] - [22/7][8]²

Wood needed to build deck = 644 - [22/7][64]

Wood needed to build deck = 644 - 201.14

Wood needed to build deck = 442.86 feet² (Approx.)

Answer:

The equation of the circle is

[tex](x - h) {}^{2} + (y - k) = {r}^{2} [/tex]

where (h,k) is the center and r is the radius.

The center is (-1,1) so plug that in the equation.

[tex](x - ( - 1)) {}^{2} + (y - 1) {}^{2} = {r}^{2} [/tex]

[tex](x + 1) {}^{2} + (y - 1) {}^{2} = {r}^{2} [/tex]

The radius of the circle is 3 so plug that in for r.

[tex](x + 1) {}^{2} + (y - 1) {}^{2} = {3}^{2} [/tex]

[tex](x + 1) {}^{2} + (y - 1) {}^{2} = 9[/tex]

Step-by-step explanation:

Exponential equation for a decreasing amount:

The exponential equation for a decreasing amount is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial rate and r is the decay rate, as a decimal.

Currently, the number of people entering a shopping mall is 109.

This means that [tex]A(0) = 109[/tex]

It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.

This means that [tex]r = 0.03[/tex]

So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 109(1-0.03)^t[/tex]

[tex]A(t) = 109(0.97)^t[/tex]

Find the total number of people entering the shopping mall at the end of 4 hours.

This is A(4). So

[tex]A(4) = 109(0.97)^4 = 96.49[/tex]

Rounding to the nearest whole number, 96 people.

Answer:

482.5 ft^2.

Step-by-step explanation:

The figure can be regarded as a rectangle with a triangle cut out of one corner.

The base of the triangle = 25-20 = 5 in and the height = 20 - 13 = 7 in.

The required area = area of rectangle - area of triangle

= 25*20 - 1/2 * 5 * 7

= 500 - 17.5

= 482.5 ft^2

9514 1404 393

Answer:

  482.5 square inches

Step-by-step explanation:

The figure can be considered to be a 25 in by 20 in rectangle with a 5 in by 7 in triangle cut off the corner. Then the area of the figure is the area of the rectangle, less the area of the triangle.

  A = LW - 1/2bh

  = (25 in)(20 in) - 1/2(5 in)(7 in) = 500 in² -35/2 in² = 482 1/2 in²

The area of the figure is 482.5 square inches.

Step-by-step explanation:

The order in which the flowers are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

4 flowers from a set of 7. So

[tex]C_{n,x} = \frac{7!}{4!(7-4)!} = 35[/tex]

The correct answer is given by option B.

Step-by-step explanation:

Note that this graph has roots at x = 1 and x = 5. Its maximum occurs at (3, 4) and it opens downward. So writing the vertex form of this graph, we get

[tex]y = - (x - 1)(x - 5)[/tex]

Then expanding this, the equation becomes

[tex]y = - {x}^{2} + 6x - 5[/tex]

As a check, note that the y-intercept is at (0, -5) so if we use x = 0 in the equation above, we see that y = -5. Similarly, if we use x = 3, the value of y is y = 4, as expected.
