Answer:

B

Step-by-step explanation:

9000-500 = 8500

8500 × (3/100) =255

8500 + 255 = 8755

8755 × (3/100) = 262.65

8755 + 262.65 = 9017.65

hence, the answer is B

*please correct me if im wrong ^^

Answer:

b) 2 years

Step-by-step explanation:

If you have $9000 in the saving account, and you take $500, you are left with:

$9000 - $500 = $8500

in one year you will have 3% more of the 8500 which is:

8500/100*3 = $255

so in one year the number on your savings account is:

8500 + 255 = $8755

and by the next year you will have 3% more of the 8755 which is:

8755/100*3 = $262.65

so in two years the number on your savings account is:

8755 + 262.65 = $9017.65

which is a little bit more than the $9000.

so it will take 2 years until the calance again reaches $9000

Answer:

27 miles

Step-by-step explanation:

Find the rate or speed that Shawn hikes at. Find this reduced to lowest terms.

speed = distance / time

speed = 12 miles / 4h

speed = 3miles / h

Every hour, Shawn hikes 3 miles.

Multiply speed by time to find distance.

3mph X 9h = 27 miles

Therefore Shawn could hikes 27 miles in 9 hours.

42. Graph a

43. Not possible.

44. Graph e

45. Graph c

46. Graph b.

Step-by-step explanation:

42. 7x + 13 ≥ 55

⇒ x ≥ 6

So, it matches graph a.

43. 12x - 8 > 4(3x + 2)

⇒ 12x - 8 > 12x + 8

Hence, d. not possible.

44. [tex]\frac{x}{- 4} - 3 < - 1[/tex]

⇒ [tex]\frac{x}{- 4} < 2[/tex]

⇒ x > - 8

Hence, graph e matches.

45. - 4(- 2x + 3) ≤ 5 + 8x

⇒ 8x - 12 ≤ 5 + 8x

⇒ - 12 ≤ 5

This is true for all values of x, hence that matches graph c.

46. - 4(x + 3) > 8(x + 3)

⇒ - 4x - 12 > 8x + 24

⇒ 12x < - 36

⇒ x < - 3

Hence, graph b matches the situation. (Answer)

Given number is 369. The number 3 is made of 5 match sticks, 6 is made of 6 match sticks and 9 is also made of 6 match sticks.

Let us try the possibilities of moving 1 match stick to make the biggest number.

(a) If the left upper match stick from 9 is moving to right upper position of 6, then the number will be 383.

(b) If the left bottom match stick from 6 is moving to left bottom position of 9, then the number will be 358.

(c) If the right upper match stick from 9 is moving to right upper position of 6, then the number will be 385.

(d) If the right upper match stick from 9 is moving to left upper position of 3, then the number will be 965.

The above four trials are shown in the below attachment.

Among these four possibilities, 965 is the biggest number.

area = 1/2(120)(252) = 15120 in²

answer: C

Answer:

C) 15,120 square inches

Step-by-step explanation:

To solve this problem we first need to convert both legs of the triangle to inches. 10 ft * 12 is 120 and 7 yards is roughly 21 ft and that times 12 is 252. All we have to do now is to plug these values into the formula for area of a triangle: 1/2(b x h) = 1/2(252 * 120) = 1/2(30240) = 15,120 square inches.

Answer:

110°

Step-by-step explanation:

Angles of a quadrilateral add up to 360:

70 + 40 + ∠B + ∠O = 360

∠B + ∠O = 250

The central angle between A and C is double the angle B.  And, it plus angle O add up to 360.

Therefore:

2∠B + ∠O = 360

Solve the system of equations.  Subtracting the first equation from the second:

∠B = 110

Answer:

154 small cubes.

Step-by-step explanation:

We are given the dimensions of the cuboid as 72 cm × 66 cm × 56 cm.

So, length of the cuboid, l = 72 cm

Breadth of the cuboid, b = 66 cm

Height of the cuboid, h = 56 cm

Capacity of cuboid = l × b × h = 72 × 66 × 56 = 266112 cm³

Now, we have to find the number of small cubes of side 12 cm each that can be placed in the given cuboid.

Now, length of each side of each small cube, s = 12 cm

Volume of each small cube = s³ = (12)³ = 12 × 12 × 12 = 1728 cm³

For calculating the number of small cubes that can be placed in the given cuboid, we will divide the capacity of given cuboid by volume of each small cube.

Required number of cubes = [tex]\frac{Capacity\; of\; cuboid}{volume\; of\; each\; small\; cube}[/tex]

⇒ Number of cubes = [tex]\frac{266112}{1728}=154[/tex]

∴ 154 small cubes each of side 12 cm can be placed inside the given cuboid of dimensions 72 cm × 66 cm × 56 cm.

Answer:

The segment is 6 units long.

Step-by-step explanation:

The points (–2, 4) and (–2, –2) are vertices of a heptagon. We have to explain how to find the length of the segment formed by these endpoints.

If two points at the ends of a straight line PQ are P([tex]x_{1},y_{1}[/tex]) and Q([tex]x_{2},y_{2}[/tex]), then the length of the segment PQ will be given by the formula  

[tex]\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}[/tex]

The area of the circle depends on the square of the radius.

The area of circle D is 36Pi centimeters squared.

The area of circle D is 324Pi centimetres squared

The area of the circle depends on the square of pi.

The area of the circle depends on the central angle.

Answer:

The following statements are true regarding the area of circle D:

Step-By-Step Explanation:

As we know, the formula for area of the circle is given by,

             [tex]A=\pi r^{2}[/tex]

Where, r = radius of the circle. In figure, CD = radius = 18 cm

So, the circle area can be measured as

            [tex]A=\pi(18)^{2}=324 \pi \mathrm{cm}^{2}[/tex]

From this, concluding that the circle area depends on radius square and its value is [tex]324 \pi \mathrm{cm}^{2}[/tex]. Hence, the statement given in option A and C are correct (reveals that option B is incorrect).  

As the Pi is constant, the circle radius cannot depend on Pi value and Option D also incorrect. The area of sector of circle only depends on ratio of central angle to entire circle (So option E also incorrect).

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [a, b ] = [ - 2, 2 ], thus

f(b) = f(2) = [tex]\frac{1}{8}[/tex] × 2³ - 2² = 1 - 4 = - 3

f(a) = [tex]\frac{1}{8}[/tex] × (- 2)³ - (- 2)² = - 1 - 4 = - 5

average rate of change = [tex]\frac{-3-(-5)}{2-(-2)}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

The average rate of change of h over the interval −2≤x≤2 is 1/2.

Here,

The function is [tex]h(x)= \frac{1}{8} x^3-x^2[/tex] and the interval −2≤x≤2.

We have to find, the average rate of change of h over the interval −2≤x≤2.

What is Average rate?

The  Average rate of change of function f( x ) in the close interval [a, b ]

is, [tex]\frac{f(a)-f (b)}{b-a}[/tex]

Now,

The function is [tex]h(x)= \frac{1}{8} x^3-x^2[/tex] and the interval −2≤x≤2.

Hence, [tex]h(-2) = \frac{1}{8} *(-2)^{3} -( -2)^{2} = -5[/tex]

And, [tex]h(2) = \frac{1}{8} *(2)^{3} -( 2)^{2} = -3[/tex]

So, Average rate of change of function h(x) = [tex]\frac{-3-(-5)}{2-(-2)} = \frac{2}{4} = \frac{1}{2}[/tex]

The average rate of change of h over the interval −2≤x≤2 is 1/2.

Divide miles ran by speed to get time:

2 miles / 8 miles per hour = 0.25 hours = 15 minutes.

2 miles / 6 miles per hour = 0.33 hours = 20 minutes.

20 minutes - 15 minutes = 5 minutes longer.

Final answer:

After calculating the time taken by each runner to complete the 2-mile race, we find that Arif took 5 minutes longer than Sharif to finish.

Explanation:

To determine how many minutes longer Arif took to complete the race compared to Sharif, we need to calculate the time each runner took to complete the 2-mile race. First, we calculate Sharif's time. Since speed is distance divided by time, we can rearrange the formula to find time: time = distance/speed.

For Sharif:

Distance = 2 miles

Speed = 8 miles per hour

Time = 2 miles / 8 mph = 0.25 hours

Convert Sharif's time from hours to minutes by multiplying by 60 minutes per hour (0.25 hours * 60 minutes/hour = 15 minutes).

For Arif:

Distance = 2 miles

Speed = 6 miles per hour

Time = 2 miles / 6 mph = 0.333... hours

Convert Arif's time from hours to minutes (0.333... hours * 60 minutes/hour = 20 minutes).

Now, to find the difference in time, subtract Sharif's time from Arif's time:

Difference = Arif’s time - Sharif's time = 20 minutes - 15 minutes = 5 minutes

Arif took 5 minutes longer than Sharif to complete the race.
