2. 656.168
3. 243.333

1. Given : 1 mile = 8/5 km

⇒ 7.5 miles = 7.5 × value of 1 mile

⇒ 7.5 miles = 7.5 × 8/5 km

⇒ 7.5 miles = 12 km

2. Given : 1m = 1.1 yard

⇒ 600m = 600 × value of 1m

⇒ 600m = 600 × 1.1 yard

⇒ 600m = 660 yards

3. Given : 1 yard = 3 feet

⇒ 1 feet = 1/3 yard

⇒ 730 feet = 730 × value of 1 feet

⇒ 730 feet = 730 × 1/3 yard

⇒ 730 feet = 243.33 yards

C is a function. X cannot repeat itself more than once, that will make it not a function. For example 1,1, 1,2, 1,3 x repeats itself 3 times that is NOT a function. Y can repeat itself more than once but X cannot.

Answer:

C is a function

Step-by-step explanation:

For every input in a relation, there should only exist one unique output. For example, in option A, the input 1 has 3 outputs which does not make it a function since they all have to be unique. Additionally, B and D aren't functions for the same reasons. Therefore, C is a function.

Which solution for 3x=10+13x?

Answers

Answer:

3x=10+13x

We simplify the equation to the form, which is simple to understand

3x=10+13x

We move all terms containing x to the left and all other terms to the right.

+3x-13x=+10

We simplify left and right side of the equation.

-10x=+10

We divide both sides of the equation by -10 to get x.

Find x in this 45°-45°-90° triangle. x = 4.5√2 9 18

Answers

Answer:

x = 9

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{9\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

x × [tex]\sqrt{2}[/tex] = 9[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )

x = 9

For a given triangle the value of x will be equal to 9.

What is trigonometry?

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

Using the sine ratio in the right triangle and the exact value

sin45° = x / 9√2 , then

x = 9√2 x sin45°

x = 9

Therefore for a given triangle, the value of x will be equal to 9.

If Dante spins the spinner below 75 times, how many times should he expect it to land on "U"?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve making assumptions

[tex]Spinner = 10\ segments[/tex]

[tex]U = 1[/tex]

[tex]n=75[/tex]

Required

Number of times to land on U

First, calculate the theoretical probability of U

[tex]Pr(U) = \frac{U}{Spinner}[/tex]

[tex]Pr(U) = \frac{1}{10}[/tex]

The expected number (E) of time to land on U is then calculated as:

[tex]E = Pr(U) * n[/tex]

[tex]E = \frac{1}{10} * 75[/tex]

[tex]E = 0.10 * 75[/tex]

[tex]E = 7.5[/tex]

Approximate

[tex]E = 8[/tex]

Step-by-step explanation:

Depends on what the question stated was pi (π). The area of the circle is 9(3 squared) * π. the shaded area is the area of the circle - the area of the triangle. The area of the triangle is base * high / 2. If the diameter of the circle (6) is what we use as the base, then 3 would be the high, making the area 9. This means the shaded area would be 9π - 9.

PLEASE ANSWER QUICKLY!!The diameter, D, of a sphere is 10.4 mm. Calculate the sphere's volume, V.
Use the value 3.14 for me, and round your answer to the nearest tenth. (Do not round any intermediate computations.

Answers

Answer:

Step-by-step explanation:

The formula for the volume of a sphere is (4/3)*pi (or in this case 3.14)*r^3, where r is the radius.

We need the radius. We are given the diameter, 10.4.

The radius is half the diameter, so 10.4/2=5.2.

Use r=5.2 and put it into the formula:

(4/3)*3.14*5.2^3≈588.7

Answers

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

---------------------------

23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

There are 280 pieces of fruit in a fruit salad. There are twice as many raspberries as blueberries, three times as many grapes as cherries, and four times as many cherries as raspberries. How many cherries are there in the fruit salad?

Answers

Answer:

64 cherries

Step-by-step explanation:

Given that

There are 280 pieces of fruit in a fruit salad

There are twice as many raspberries as blueberries,

three times as many grapes as cherries,

and four times as many cherries as raspberries

We need to find out the number of cherries in the fruit salad

So,

Let us assume the blueberries be x

So, the raspberries be 2x

Cherries be 8x

And, grapes be 24x

Now

x + 2x + 24x + 8x = 280

35x = 280

x = 8

hence, the No of cherries in the salad

= 8 x

= 8(8)

= 64 cherries

Two vertical angles have a sum of their measures that is 60 degrees.What is the measure of each angle?

Answers

Answer:

Measure of each one of the vertical angles = 30 degrees.

Step-by-step explanation:

Vertical angles are equal and opposite. If we have two vertical angles it means that both angles are equal .

As both angles are equal let both the angles be represented by x

Their sum is given by

x+x= 60 degrees

2x= 60 degrees

x= 60/2 degrees

x= 30 degrees

Measure of each one of the vertical angles = 30 degrees.

For each expression, write an equivalent expression that only uses addition a. 20 - 9 + 8 -7 b. 4x - 7y - 5z + 6 c. -3x - 8y - 4 - 8/7z

Answers

Answer:

a. =11+ 1

c. (-3x) + (-8y) +(-4)+(-8/7z)

Step-by-step explanation:

a. 20 - 9 + 8 -7

=11+ 1 ( this is obtained by solving)

b. 4x - 7y - 5z + 6

=4x+ (-7y) + (-5z) +6

We multiply the negative sign with the positive sign to get a minus so the answer remains the same and the expression is written as an addition sum.

c. -3x - 8y - 4 - 8/7z

-[ 3x+8y+4+8/7z]

(-3x) + (-8y) +(-4) +(-8/7z)

The minus sign is taken as common leaving the expression with the plus only.

It can be written in the same manner as above, adding the negative terms so that the expression is written as a sum.

What are the coordinates of the point on the directed line segment from
(−8,1) to (2,−7) that partitions the segment into a ratio of 3 to 1?

Answers

Answer:

The desired point is thus (-1/2, -5).

Step-by-step explanation:

The x-component of this directed line segment is 2 - (-8), or 10, and the y-component is -7 - (1), or -8. This segment is in Quadrant II, since the x-component is positive and the y-component is negative.

The point of interest is (3/4) of the way in the positive x-direction from x = -8. We can express this symbolically as -8 + (3/4)(10), or -8 + 7.5, or -1/2.

The point of interest is 3/4 of the way in the negative y direction from 1, or:

1 + (3/4)(-8), or 1 - 6, or -5.

The desired point is thus (-1/2, -5).

During a race sample of five sports cars has a mea speed of 175mph. The speeds in miles per hour of cars are 186,181,170,151, find the speed of the five car

Answers

Answer:

Speed of 5th car = 187 mph

Step-by-step explanation:

Given:

Mean speed of five car = 175 mph

Speed of four cars = 186,181,170,151 mph

Find:

Speed of 5th car

Computation:

Average mean = Sum of all observation / Number of observation

Mean speed of five car = Sum of five cars speed / Number of cars

175 = [186 + 181 + 170 + 151 + Speed of 5th car] / 5

186 + 181 + 170 + 151 + Speed of 5th car = 175 x 5

186 + 181 + 170 + 151 + Speed of 5th car = 875

688 + Speed of 5th car = 875

Speed of 5th car = 875 - 688

Speed of 5th car = 187 mph
