Answer:

(B). 15.75

Step-by-step explanation:

If Kristens dog weighs 2.5 pounds less, then you just have to subrtact 2.5 from 18.25

The answer is B. 15.75 pounds. Kristen's dog weighs 2.5 pounds less than Milo's dog which is 18.25. So, all you have to do is subtract 2.5 from 18.25. 18.25 - 2.5 = 15.75.

Answer:

i have that same Question

Step-by-step explanation:

Usual speed is given by :

[tex]s = \dfrac{45\times 60}{35} \ mph\\\\s=77.14 \ mph[/tex]

Now, we want to reach job exactly at 10 : 00 .

So, time taken is , t = 10:00 - 09:30

t = 30 minutes = 0.5 hours .

New speed is :

[tex]s'= \dfrac{45}{0.5} = 90 \ mph[/tex]

Therefore, increase in speed is ( 90 - 77.14 ) = 12.86 mph.

Hence, this is the required solution.

Answer:

164

Step-by-step explanation:

65+65=130

17+17=34

130+34=164

Answer:

You will need 164 feet of fencing.

Step-by-step explanation:

Add up 17+17+65+65 or follow along to the perimeter formula to get your answer of 164 feet.

Answer:

Solve the equation so it is in the y=mx+b form.

Step 1. 6x+9y = 216

Step 2. 9y = -6x+216

Step 3. y = -6/9x+24

Step 4. Simplify/Reduce to get y = -2/3x+24

Since it is Parallel then the slope is the same so the slope is -2/3x.

The slope of line parallel to line with equation → 6x + 9y = 216 is

m = -2/3.

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.

Given is a line which is parallel to a line whose equation is 6x + 9y = 216.

We know that the general equation of straight line is -

y = mx + c             ... Eq [ 1 ]

where 'm' represents the slope of the line.

The equation of line given -

6x + 9y = 216.

Rearranging it -

9y = - 6x + 216

y = (-6/9)x + (216/9)

y = (-2/3)x + 24              ... Eq [ 2 ]

Comparing Eq[2] with Eq[1], we get -

m = -2/3

Therefore, the slope of the line with equation → 6x + 9y = 216 is -2/3.

Two parallel lines have same slope. Hence, the slope of line parallel to

line with equation → 6x + 9y = 216 is -2/3

Therefore, the slope of line parallel to line with equation →

6x + 9y = 216 is -2/3.

Answer: D, F, G / 4, 6, 7

Step-by-step explanation:

We have the following equations:

5 + 3x - 2 and x + 2(x+1) + 1

Before checking the statements. Let's solve the syste of equations:

5 + 3x - 2 = x + 2(x+1) + 1

5 + 3x - 2 = x + 2x+2 + 1

3x + 3 = 3x + 3

Both equations are equivalent. Now, let's judge the statements:

1. The expressions are only equivalent when evaluated with odd values.

Given that the both expression are the same, the expressions are equivalent for ALL values.

Therefore, the statement IS FALSE ❌

2. The expressions are only equivalent for x=3 and x=7.

Given that the both expression are the same, the expressions are equivalent for ALL values, not only x=3 and x=7.

Therefore, the statement IS FALSE ❌

3. The expressions should have been evaluated with one odd value and one even value.

If two expressions are equivalent, they should be equivalent for ALL values. Sometimes, evaluating just one odd and one even value isn't enough. That's why the best approach is to solve the system of equations.

Therefore, the statement IS FALSE ❌

4. The expressions have equivalent values when x=6.

Given that the both expression are the same, the expressions are equivalent for x=6 (And all the real values too).

Therefore, the statement IS TRUE ✅

5. When x=0, the first expression has a value of 3 and the second expression has a value of 4.

Given that BOTH expressions are equvalent, they have the same value when x=0, which is 3.

Therefore, the statement IS FALSE ❌

6. The expressions have equivalent values for any value of x.

Given that the both expression are the same, the expressions are equivalent for ALL values of x.

Therefore, the statement IS TRUE ✅

7. When x=10, both expressions have a value of 33

Given that the both expression are the same, the expressions are equivalent for ALL values of x. That's why when x=0, both expressions have a value of 33.

Therefore, the statement IS TRUE ✅

Answer:

D. Zn(NO3)2 + Cu

Step-by-step explanation:

The correct chemical equation for the replacement reaction of Cu(NO3)2 and Zn is:

Zn + Cu(NO3)2 → Zn(NO3)2 + Cu

A replacement reaction is a chemical reaction in which an element displaces or replaces another element in a compound. In other words, one element takes the place of another element in a compound.

The general equation for a replacement reaction is:

A + BC → AC + B

We have,

The reaction between copper nitrate (Cu(NO3)2) and zinc (Zn) is an example of a single replacement or displacement reaction, which involves the replacement of one element in a compound by another element.

In this reaction,

Zinc (Zn) reacts with copper nitrate (Cu(NO3)2) to form zinc nitrate (Zn(NO3)2) and solid copper (Cu).

The reaction is driven by the relative reactivity of the metals involved.

Zinc is more reactive than copper, which means that it has a greater tendency to lose electrons and form positive ions.

Copper, on the other hand, is less reactive and has a greater tendency to stay in its elemental form.

When zinc is added to copper nitrate solution, the zinc atoms lose electrons and become positively charged ions, while the copper ions in the solution gain electrons and become solid copper.

The zinc ions then combine with nitrate ions (NO3-) from the copper nitrate solution to form zinc nitrate, which remains in the solution.

The balanced chemical equation for the reaction shows that one molecule of zinc (Zn) reacts with one molecule of copper nitrate (Cu(NO3)2) to form one molecule of zinc nitrate (Zn(NO3)2) and one molecule of solid copper (Cu).

Thus,

The correct chemical equation for the replacement reaction of Cu(NO3)2 and Zn is:

Zn + Cu(NO3)2 → Zn(NO3)2 + Cu

Answer:

Of course it doesn't work, 3 x 24 = 72, not 32 (3 tens and 2 ones)

Step-by-step explanation:

This method is similar to decomposition, but it doesn't work. The problem is that she is mixing multiplication, division and addition all together without any sense at all. The way decomposition works is as follows.

Examples of decomposition:

first you can multiply 3 x 4 = 12

then 3 x 20 = 60

add them and you get 72

for example: 6 x 122

6 x 2 = 12

6 x 20 = 120

6 x 100 = 600

add them together = 732

another example: 9 x 356

9 x 6 = 54

9 x 50 = 450

9 x 300 = 2700

add them to get 3,204

Answer:

D'(-4, 1)

Step-by-step explanation:

Polygon ABCDEF is transformed by number of steps given in the question.

We have to find the coordinates of point D'.

Coordinates of point D → (2, -2)

Step - 1,

Polygon rotated 90° counterclockwise about the origin,

Rule for this rotation,

(x, y) → (-y, x)

Coordinates of image E after rotation,

D(2, -2) → E(2, 2)

Step - 2,

Point E then reflected across the line y = -x,

Rule for the reflection,

(x, y) → (-y, -x)

Image of E after reflection will be,

E(2, 2) → F(-2, -2)

Step -3,

Then point F was translated up by 3 units and 2 units left,

Rule for the translation,

(x, y) → (x -2, y + 3)

Image of F will be point D',

F(-2, -2) → D'(-4, 1)

Answer:

The area of the square is 2.25cm

Step-by-step explanation:

Here's what we know:

-Each letter represent a side

-A square is made up of 4 congruent sides

-To find the area of a square you need 2 sides

-We have 2 sides (A and B)

Now we can solve:

If 3cm is the length of A and B together, then we can determine that separately The sides are 1.5cm. We can then multiply 1.5 by itself to get 2.25cm.
