Answer:

B. Ferrari and Jaguar is the answer

Answer: B

Step-by-step explanation:

Answer:

If the secant = 2, this would be where the cosine = 1/2 = a 60° degree angle in the first quadrant and the 4th quadrant.

And the cot (60°) = 1/√3 = √3 /3

And the cot of a 60° angle in the 4th quadrant (i.e., 330°) is (- √3 /3)

Answer:

All points satisfy the inequality

Step-by-step explanation:

Given

[tex]5x + 2y \le 26[/tex]

Required

Select all points that satisfy the above inequality

[tex](a)\ (0,5)[/tex]

This implies that

[tex]x = 0; y = 5[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * 0 + 2 * 5 \le 26[/tex]

[tex]0 + 10 \le 26[/tex]

[tex]10 \le 26[/tex]

This satisfy the inequality

[tex](b)\ (3,1)[/tex]

This implies that

[tex]x = 3;\ y =1[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * 3 + 2 * 1 \le 26[/tex]

[tex]15 + 2 \le 26[/tex]

[tex]17 \le 26[/tex]

This satisfy the inequality

[tex](c)\ (3,-4)[/tex]

This implies that:

[tex]x = 3; y-4[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * 3 + 2 * -4 \le 26[/tex]

[tex]15 -8 \le 26[/tex]

[tex]7 \le 26[/tex]

This satisfy the inequality

[tex](d)\ (-4,1)[/tex]

This implies that:

[tex]x = -4; y =1[/tex]

So, we have:

[tex]5x + 2y \le 26[/tex]

[tex]5 * -4 + 2 *1 \le 26[/tex]

[tex]-20 + 2 \le 26[/tex]

[tex]-18 \le 26[/tex]

This satisfy the inequality

Answer:

Susan spilled 1/6 of a gallon of lemonade.

Step-by-step explanation:

Since Susan was carrying a pitcher that contained 2/3 of a gallon of lemonade to the table for lunch, and she slipped and spilled 1/4 of the lemonade in the pitcher, to determine what fraction of a gallon of lemonade did she spill the following calculation must be performed:

2/3 = 0.6666

0.666666 x 1/4 = X

0.166666 = X

0.166666 = 1/6

Therefore, Susan spilled 1/6 of a gallon of lemonade.

Answer:(1) 11-2n is the correct answer

Step-by-step explanation:

Answer:

perimeter of square=4×side

perimeter of square =4×13cm

perimeter of square = 52cm

area of square = side²

area of square = (13cm)²

area of square = 169cm²

Answer:

52 cm / 169 cm²

Step-by-step explanation:

To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.

13 + 13 + 13 + 13 = 52

The perimeter is 52 cm.

The area is the length times the width of the shape, so we have to multiply 13 by 13.

13 · 13 = 169

The area is 169 cm².

The answer is the third option, 52 cm / 169 cm².

Good luck :)

Answer:

  x = 5

  FD = 22

Step-by-step explanation:

The products of the segment lengths on the same chord are the same.

  8×15 = 12×(3x -5)

  10 = 3x -5 . . . . . . . divide by 12 (we use this value to find FD)

  15 = 3x

  5 = x

__

FD = (3x -5) +12 = 10 +12

FD = 22

Answer:

1. 15.7 in

2. 153.9 cm

Step-by-step explanation:

The circumference of a circle is found by the formula:

C = 2 * pi * r, where r represents the radius.

For the first circle, we substitute in 3.14 for pi and the given radius:

C = 2 * 3.14 * 2.5

C = 15.7 in

However, for the second circle, the diameter is given instead of the radius.

As the radius is just half of the diameter, we can find that it is 24.5 cm.

Substituting the values in, we get:

C = 2 * 3.14 * 24.5

C = 153.86 cm

Rounding to the nearest tenth gives us:

153.9 cm

Make sure to use the correct units for each question.

Answer:

28716.35 mm³

Step-by-step explanation:

The formula of volume of sphere

[tex] = \frac{4}{3} \pi {r}^{3}[/tex]

The volume of the sphere

[tex] = \frac{4}{3} \times 3.14 \times {(38 \div 2)}^{3} [/tex]

[tex] = \frac{4}{3} \times 3.14 \times {19}^{3} [/tex]

[tex] = \frac{86149.04}{3} [/tex]

[tex] = 28716.34667...[/tex]

= 28716.35 mm³ (rounded to the nearest hundredth)

Answer:

y = 30

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in 20 as y and 8 as x, then solve for k:

y = kx

20 = k(8)

2.5 = k

So, the equation is y = 2.5x

Plug in 12 as x, and solve for y:

y = 2.5x

y = 2.5(12)

y = 30

So, when x = 12, y = 30

Answer:

[tex] \displaystyle V _{ \text{cuboid}} =280 {in}^{3} [/tex]

Step-by-step explanation:

We are given the area of the base and the measure of the height of a solid figure . We want to find the volume of the figure.

Notice that the area of the base of the figure is not a perfect square. Thus, we assume the solid figure to be a cuboid.

Cuboid is a three dimensional rectangle. The dimensions of cuboid are length, width and height

Remember that

[tex] \displaystyle V _{ \text{cuboid}} = l\times w \times h[/tex]

Since the base area (l×w) is 40in² and height (h) is 7in, simply substitute:

[tex] \displaystyle V _{ \text{cuboid}} =40 \times 7[/tex]

simplify multiplication:

[tex] \displaystyle V _{ \text{cuboid}} =280[/tex]

hence,

The volume of the figure is 280 in³

Step-by-step explanation: Since we have given, P(A) = 0.75 and P(A|B) =0.8 .

So, P(A∩B) = P(B|A)× P(A) = 0.8×0.75 =0.6 .

We have given P(B|A') = 0.6

P(A’∩B) = P(B|A')×P(A') = 0.6 × 0.25 = 0.15.

P(B) = P(A∩B) + P(A'∩B) = 0.6 + 0.15 = 0.75.

=> P(A|B) = (∩)()=0.60.75

Answer:

17. 25 [tex]in^2[/tex]

18. 53 [tex]m^2[/tex]

19. 21.6 [tex]cm^2[/tex]

20. 20.8 [tex]km^2[/tex]

Step-by-step explanation:

The area of a parallelogram is simply the base multiplied by the height.

17.

Base = 5 in

Height = 5 in

Area = Base * Height

Area = 5 * 5

Area = 25 [tex]in^2[/tex]

18.

Base = 10 m

Height = 5.3 m

Area = Base * Height

Area = 10 * 5.3

Area = 53 [tex]m^2[/tex]

19.

Base = 5.4 cm

Height = 4 cm

Area = Base * Height

Area = 5.4 * 4

Area = 21.6 [tex]cm^2[/tex]

20.

Base = 5.2 km

Height = 4 km

Area = Base * Height

Area = 5.2 * 4

Area = 20.8 [tex]km^2[/tex]
