In the diagram below, DE is parallel to XY. What is the value of y?​

Answer:

y≥-10

Step-by-step explanation:

First step when you are give numbers, make a formula:

y+9≥-1

The next step is simply to subtract 9 from both sides to isolate the variable.

y≥-10

i hope this helps u!

pls five thanks and brainliest ;)

Answer:

18 tons

Step-by-step explanation:

a) Given: Weight of 1 truck=4500 pounds

Thus, weight of 8 trucks=  pounds

We know that 1 ton=2000 pounds

Thus, weight of 8 trucks in tons=

Hence, the total weight in tons the cars on the truck= 18 tons.

b) Given: Dimensions of the room are as

Length=10 yards and width= 168 inches

We know that 1 yard=3 feet and 1 inch=

Thus, length

width=

The difference between length and width=

Hence, the length of the room exceed the width by 16 feet.

Answer:

$90

Step-by-step explanation:

$120 x .75 = $90

Answer:

The answer is x  =  13.32182916

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Multiply  30.5  by  15.2 .

463.6  ⋅  x  =  6176

Divide each term by  463.6  and simplify.

Hoped this helped!

Brainly, please?

Answer:

13.32

Step-by-step explanation:

30.5 times 15.2 is 463.6

So now the equation is 463.6x=6176

divide both sides by 463.6

x= 13.32

Answer:

3 spoons and 6 forks

Step-by-step explanation:

9 = x + y; x= 9-y

44 = 4x + 6y

44 = 4(9-y) + 6y

44 = 36 - 4y +6y

44 = 36 +2y

2y = 44-36 = 12

y = 12/2 =6

x= 9-y = 9-6 =3

Answer:

-23.21

there should be a two part for this and the answer would be D y= 0.15x - 23.21

Step-by-step explanation:

The line of best will be y = 0.15x - 23.21  and the y-intercept is -23.21 after applying the formula.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

The data is given:

R(x)     W(y)

808     93

768     94

655     66

684     81

637     86

619     75

613     61

609     69

563     55

The line of best fit can be written as:

y = mx + c

Here m is the slope of the line best fit and c is the y-intercept

Putting the values in the formula we get:

m = 0.15

c = -23.21

The line of best fit is:

y = 0.15x - 23.21

Thus, the line of best will be y = 0.15x - 23.21  and the y-intercept is -23.21 after applying the formula.

Answer:

-7

Step-by-step explanation:

I'm guessing y=0

0=x+7

-7=x

Answer:

you substitute x for 4

Step-by-step explanation:

so its f(x) and f(4) so you use 4 for x so you would solve f(x)=3(4)+2

Answer:

D

Step-by-step explanation:

Answer: -2 1/2

Step-by-step explanation:

First term = a = -40

Common ratio = 2nd term / First term = 20 / -40 = -1/2

5th term = ar⁴

5th term = -40 × (-1/2)⁴

5th term = -40 × 1/16

5th term = -2 1/2

Answer:

I'm pretty sure the first one is b

Answer:

20ft

Step-by-step explanation:

Use ratios:

[tex]\frac{5}{8} = \frac{x}{32}[/tex]

Solve for x

x = 20

Answer:

x = 20

Step-by-step explanation:

Let’s think about it this way ( i’m gonna make this as easy as possible! )

So, x is the variable, which it represents the height of the tree right? so you’re gonna want to take the shadow of the alien, and think “well can 8 make 32? and if so how many times?” which would be 8y = 32. and yes you can. so let’s think about that. how many times does it take for 8 to get to 32?

8, 16, 24, 32

so it takes 4 times. then you think “ well if 8x4 got the shadow length, 5x4 must get the tree height” which is correct.

you’ll take 5 x 4 which is 20, and you will put that down as the heigh of the tree, or think 20ft.

so x = 20.

Answer:

The answer is below

Step-by-step explanation:

In a certain​ year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.

Plot a graph for t > 0

how many days it will take to get 200 pounds of garbage.

Solution:

a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:

At t = 0; A = 7.5(0) = 0

At t = 10; A = 7.5(10) = 75

The graph was plotted using the geogebra online graphing tool.

b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:

A = 7.5t

t = A / 7.5 = 200 / 7.5

t = 26.67 days

x < 3

Answer:

60

Step-by-step explanation:

To get the area of a right triangle (a triangle with an angle of 90 [represented by the box in the corner]) you have the formula of

Area = (a*b) divided by 2

a = one side of the triangle

b = another side of the triangle

Neither side are the hypotenuse.

Answer:

In the given problem, we can write a similarity statement relating to the three triangles in the diagram. And the answer is letter "D" triangle JKM≈ triangle MKL ≈ triangle MJL. We have arrived in this due to the ratios of corresponding legs of the three triangles and also because of same angles formed in the triangles.
