Answer:

20%

Step-by-step explanation:

Divide 16 by 80 and you get 0.2 as an answer and to get a percent you move the decimal 2 places to the right to fet 20%

Isabel has completed 20 percent of the race of 80 miles.

A percentage is a quantity or ratio that, in mathematics, represents a portion of one hundred. It is one method for illustrating a relationship between two integers that has no dimensions.

Given, Isabel has ridden 16 miles of a bike course. The course is 80 miles long.  From the general formula of percentage:

For the percentage, we have to divide the value by the total value and then multiply the result by 100.

percentage of the course has Isabel ridden so far = (16/80) * 100

percentage of the course has Isabel ridden so far = 1/5*100

percentage of the course has Isabel ridden so far = 20%

Therefore, Isabel has ridden 20 percent of the course which is 80 miles.

The height of the trapezoid has a length of 4 units

From the question, we are to determine the height of the trapezoid

The area of a trapezoid can be calculated by the formula,

[tex]A = \frac{1}{2}(a+b) h[/tex]

Where A is the area

a and b are the bases

and h is the height

The median of a trapezium is given by

[tex]\frac{1}{2} (a+b)[/tex]

From the given information,

A = 96 square units

[tex]\frac{1}{2}(a+b) = 24 \ units[/tex]

Putting the parameters into the formula,

96 = 24 × h

h = 96 ÷ 24

h = 4 units

Hence, the height of the trapezoid has a length of 4 units

Ok so I am not exactly sure if you want to know how many whole cups can be added or simply how many 2/3 cups make up 10, but heres what I found.

So to find how many 2/3 is in 10 cups you simply have to divide

10/(2/3) = 15

So 10 cups of flour is 15 (2/3) cups of flour.

Option 1,3,4,6 are correct

Explanation

Step-by-step explanation:

we have formula for discriminant that is D=b^{2} -4acD=b

2

−4ac

when D>0 the roots are real and unequal

when D= 0 roots are real and equal

and when D< 0 roots are imaginary or not real and unequal

In 1st equation: x^2+6x+8x

2

+6x+8

a=1,b=6,c=8 on substituting the values in the formula we will get

D=6^2-4(1)(8)=4 > 0D=6

2

−4(1)(8)=4>0 hence real and unequal roots.

In 2nd equation:x^2+4x+8x

2

+4x+8

a=1,b=4,c=8 on substituting values in formula

D=4^2-4(1)(8)=-16 < 0D=4

2

−4(1)(8)=−16<0 so roots are not real

In 3rd equation x^2-12x+3x

2

−12x+3

a=1,b=-12,c=3 on substituting values

D=D=(-12)^2-4(1)(3)=132 > 0D=(−12)

2

−4(1)(3)=132>0 roots are real and unequal

In 4th equation: x^2+4x-1x

2

+4x−1

a=1,b=4,c=-1 on substituting the values

D= 4^2-4(1)(-1)=20 > 0D=4

2

−4(1)(−1)=20>0 real roots

In 5th equation:5x^2+5x+45x

2

+5x+4

a=5,b=5,c=4 on substituting the values

D=5^2-4(5)(4)=-55 < 0D=5

2

−4(5)(4)=−55<0 roots are not real

In 6th Equation: x^2-2x-15x

2

−2x−15

a=1,b=-2,c=-15 on substituting the values

D=(-2)^2-4(1)(-15)=64 > 0D=(−2)

2

−4(1)(−15)=64>0 roots are real

Answer:

-0.25268 rad + 2πn  ,   3.394273 rad + 2πn

 ≈  - π /12 + 2πn,   π + 2πn

Step-by-step explanation:

sin( x ) = -0.25

x = sin^-1 ( -25 )

 The solutions of the equation  sin( x ) = -0.25 are :

X = -0.25268rad + 2πn  ,    3.394273rad + 2πn

  ≈  - π /12 + 2πn,   π + 2πn

Answer:

268 in²

Step-by-step explanation:

The surface area is basically the entire area of the figure. You can do it multiple ways, but this is how I did it. I found the area of each side and added them all together. There are three sets of identical sides. First, we'll calculate the area of the side with lengths 10" and 8".

10 · 8 = 80

There are two of these sides, so currently we have 80 + 80.

Next, the area of the sides with lengths 8" and 3". These are the sides at the top and bottom.

8 · 3 = 24

So to our equation we now have 80 + 80 + 24 +24.

For the final two sides, we have the dimensions 10" and 3".

10 · 3 = 30

To our equation, we add this to get 80 + 80 + 24 + 24 + 30 +30.

Add all these numbers together for 268.

In the correct form, we add the square symbol to show that we are talking about area. The answer is 268 in². Good luck :D
