Answer:

x ≥ -4

Step-by-step explanation:

you subtract 10 on both sides to get x by itself. 6-10 = -4. since you already have x by itself you don’t have to do anymore

Answer:

The answer is x ≥ -4

Step-by-step explanation:

First, subtract 10 from both sides.

x + 10 ≥ 6

 -  10   - 10

Which would make x ≥ -4.

what is the area of the triangle?

Answers

Answer:

S = S(ABCD) - S(BCE) - S(AED) = 7*6 - 2*6/2 - 5*6/2 = 42 - 6 - 15 = 21

Step-by-step explanation:

If we look at the picture, we can notice that the area we are interested in is S(ABCD) - S(BCE) - S(AED). Y-axis is parallel to AB line since the coordinates of the A and B points have the same X-axis value.

The following calculations happend for figuring out the width for each line:

AB = | -3 - 4 | = 7BC = | -4 - 2 | = 6CE = | 4 - 2 | = 2ED = | 2 - (-3) | = 5AD = | -4 - 2 | = 6

The formulas for each figure area:

S(ABCD) = AB * BCS(BCE) = BC * CE / 2S(AED) = ED * AD / 2
i agree that it is 21

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55


Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

28 out of 50 8th graders said they prefer snow to rain. 42 out of 58 10th graders said they prefer snow. did a larger percentage of 8th graders or 10th graders prefer snow?

explanation please

Answers

A larger percentage of 10th graders preferred snow.

Answer:

10th graders prefered snow then 8th graders did.

Step-by-step explanation:

Hey I hope I will be able to help!

To find out the percentage we need to divide the fractions-

28 divided by 50 = 0.56 and in percentage form its 56%

42 divided by 58 = approximately 0.72 which is 72%

56% < 72%

72% is obviously greater so 10th graders prefer snow more than 8th graders do.

A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?

Answers

Answer:

n=90

Step-by-step explanation:

As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one  

so volume = length * width * height

volume of larger prism

vp=45/4 ft^3 =11.25

volume of small cubes

vs=1/2*1/2*1/2

vs=0.125 ft^3

now numbers of cube that can fit

n=vp/vs

n= 11.25/.125

n=90

so 90 smaller cubes will completely fill in the prism

Answer:

11.25 [tex]ft^3[/tex]

Step-by-step explanation:

2.5 x 3 x 1.5 = 11.25 [tex]ft^3[/tex]

The mean of given data is 5 and mean deviation is 1.25

What is mean deviation?

The mean deviation is defined as a statistical measure that is used to calculate the average deviation from the mean value of the given data set.

Mean = Sum of all observation/ Number of observation

         = 40 / 8

         = 5

Mean Deviation = ∑FD/n

143, multiply 9 and 12 then you get 108. Then subtract 7 from 12 to get the length of the top square an that is 5 then you multiply 5 and 7 to get 35 you add that to 108 and get 143 hope this helps:)

The number of square feet of carpet Sara needs is 128 square feet.

What is area?

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

From the given figure,

Dimensions of a large rectangle, length is 12 ft and breadth is 9 ft.

Area of the large rectangle = Length×Breadth

= 12×9

= 108 square feet

Dimensions of a smaller rectangle, length is 12-7=5t ft and breadth is 13-9=4 ft.

Area of the smaller rectangle = Length×Breadth

= 5×4

= 20 square feet

Total area = 108+20

= 128 square feet

Therefore, the number of square feet of carpet Sara needs is 128 square feet.
