Tina's Jack Russell weighed 19.5 pounds. This week, her dog weighed 21.8 pounds. Find the percent of change in the weight of her dog?

Answer:

17 hours

Step-by-step explanation:

givens:

-he made $253 for 11 hours of work

-how many hours of work for $391

set a proportion

253       391

----- =   ----

11          h                          h=hours

cross multiply

253h=391 times 11

253h=4301

divide 253 in both sides

4301/253

17 hours!

Step-by-step explanation:

Answer: The length of JF = 16 units.

Step-by-step explanation:

Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.

i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]

If  EJ is 3y-8 and JF is 7y-40.

Then, [tex]3y-8=7y-40[/tex]

[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]

JF= 7(8)-40 =56-40= 16 units

Hence, the length of JF = 16 units.

Step-by-step explanation:

Answer:

G is not a function

Step-by-step explanation:

Answer:

H.

Step-by-step explanation:

something is represented as a function when none of the inputs (x) repeat, but the outputs (y) change. the graph for letter G has repeating x values, but the y values don't change when an x repeats. however, the graph for letter H has repeating inputs (x), but the outputs are different, even with the same input.

that's why parabolas aren't functions (if you know what those are).

hopefully that helps and isn't too confusing! if you need anything else, let me know! :)

Answer:

The width is 20.625 and the length is 19.375

Step-by-step explanation:

Let 2 1/2 + w = length

Let w = width

Equation:

2 1/2 + w + w = 80                     Combine liked terms

2 1/2 + 2w = 80                    

-2 1/2         -2 1/2                        Subtract 2 1/2 from both sides

2w  =   77.5

÷ 2     ÷ 2                                    Divide 2 from both sides

w = 41.25

Length:

2 1/2 + 41.25 = 165/4 or 38.75

Width:

41.25

41.25/2 = 20.625

38.75/2 = 19.375

Answer:

B   -------   DE ≅ RS

it's B because DE and RS both contain the equal angles.

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.

A = 16/4 marked blocks = 25%

B = 16/8 marked blocks = 50%

C = 16/6 marked blocks = ?

D = 16/10 marked blocks = 62,5%

So answer would be A

Answer: Cost= 25 +0.2*25

Step-by-step explanation:

Answer:

is A  

Step-by-step explanation:

The answer choice A is correct because it correctly shows both numbers.All of the other answer choices didnt correctly show the answer choices,and they only showed part of the correct answers.So therfore your correct answer is A(hope this helps you if it doesnt tell me)

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

Answer:

76

Step-by-step explanation:

This is easy. All you need to do is set up a proportional relationship.

A proportional relationship uses variables to show similarities, in this case, in triangles.

[tex]\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2[/tex]

x represents the missing side.

Step-by-step explanation: The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
