Answer:

8 < 8.2 <8.5

Step-by-step explanation:

Pick a number that is greater than 8 but less than 8.5.

Ex: 8.1, 8.2, 8.3, 8.4

Answer:

3 and 8 are supplementary

4 is congruent to 8

3 is congruent to 1

Answer:

the answer is x1 = -4- square root of 23 x2= -4+ square root of 23

Answer:

d. y=5x-3

Slope-intercept form is y=mx+b.

m= slope

b= y intercept

so, m=5 and b= -3

Substitute with those values and then you have the equation.

Answer:

1/3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone = 1/3(nr^2h)

n = 22/7

r = radius  

h = height

If the volume of a cylinder is 300, the volume of a cone = 1/3 x 300 = 100

the capacity of a cone is 1/3 that of a cylinder

Answer:

Given an expression with a rational exponent, write the expression as a radical. Determine the power by looking at the numerator of the exponent. Determine the root by looking at the denominator of the exponent. Using the base as the radicand, raise the radicand to the power and use the root as the index

Answer:

x = - 1

Step-by-step explanation:

Given

- 5 - 3 (x + 1) = - (- 4x + 1) ← distribute parenthesis on both sides

- 5 - 3x - 3 = 4x - 1

- 3x - 8 = 4x - 1 ( subtract 4x from both sides )

- 7x - 8 = - 1 ( add 8 to both sides )

- 7x = 7 ( divide both sides by - 7 )

x = - 1

Answer:

For angle B which is 50 degrees,

hypotenuse = AB =?

Adjacent = BC = 2 units......(given)

cos 50 = adjacent / hypotenuse

0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)

AB * 0.643 = 2

AB = 2 / 0.643

AB = 3.11 units(approx)

Step-by-step explanation:

Given that,

Perpendicular = 17 units

Hypotenuse = 25 units

We need to find the value of x.

Using Pythagoras theorem to find x.

Hypotenuse² = base²+perpendicular²

25² = x² + 17²

x = 18.3 units

So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.

Answer:

-20u + 12y + 4

Step-by-step explanation:

We have the equation -4(5u - 3y - 1) and are asked to use the distributive property to remove the parenthesis.

When using the distributive property, you have to multiply the number outside the parenthesis to all numbers inside the parenthesis, do as followed :

-4(5u - 3y - 1)

(5u(-4) -3y(-4) -1(-4))

-20u + 12y + 4

Answer:

A: 19:26 B:7:8 C:26:45

Step-by-step explanation:

Question A

First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,

Boys

9+10=19

Girls

12+14=26

Now that you have the total number of boys and girls you make this ratio,

19:26

That is the final answer

Question B

For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,

Fifth Graders

12+9=21

Sixth Graders

14+10=24

Now that you have the total number of both of the different grades you make this ratio,

21:24

You can simplify this by finding the lowest common factor which would be

7:8

Question C

To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.

Girls

12+14=26

All

12+9+14+10=45

Now with the total number of both you will form a ratio

26:45

This is your final answer because you cant simplify this any further
