Which of the following does not have the same value as the whole number 4?

3 5/5
1/4
4/1
3 4/4

9514 1404 393

Answer:

  3.  62.5% decrease

  4.  26.2% decrease

  5.  13.2% decrease

Explanation:

A percentage change is calculated from ...

  percent change = ((new value) - (old value))/(old value) × 100%

When it is negative, the change is a decrease.

__

3. (24 -64)/64 × 100% = -40/64 × 100% = -62.5%, a 62.5% decrease

__

4. (4.8 -6.5)/6.5 × 100% = -1.7/6.5 × 100% ≈ -26.2%, a 26.2% decrease

__

5. (1.12 -1.29)/1.29 × 100% = -0.17/1.29 × 100% ≈ -13.2%, a 13.2% decrease

Answer: x = 5.625

Step-by-step explanation:  The triangles are similar; the side lengths of the large triangle are proportional to the lengths of the small triangle. The corresponding parts are proportional.

Use proportion. The total length of side FV is 16.

6:16 = x:15 . or 6/16=x/15

cross multiply 15 × 6 = 90, then divide 90/16

90/16 = x

5.625 = x

Answer: b=112 degrees and c=68

Step-by-step explanation:

Answer:

b = 112, c = 68

Step-by-step explanation:

The angle of a line is 180 degrees.

If an angle is 112, 180-112=68 so that blank space will be 68 degrees.

180-68=112, so b=112.

Since b is 112, we now that c is 68.

Answer:

x = -1/7

Step-by-step explanation:

Solve for x

9-17x-5-4x=7

Combine like terms

-21x +4 = 7

Subtract 4 from each side

-21x-4+4 = 7-4

-21x = 3

Divide each side by -21

-21x/-21 = 3/-21

x = -1/7

Check

9 - 17(-1/7) -5 -4(-1/7) =7

9 + 17/7 -5 + 4/7 =7

4 +21/7 = 7

4+3 = 7

7=7

Answer:

There were 35 children and 38 adults at the pool that day.

Step-by-step explanation:

You can use substitution to solve this answer. When solving equations with substitution, ask yourself "how many?" and "how much?" to create two equations:

1.25c+2.25a=126.25  (this equation tells us the dollar value)

c+a=73.   (this equation tells us quantity, or how many)

1. Solve for 1 variable and plug it into the other equation.

a=73-c   -----> 1.25c+2.25(73-c)=126.25

2. Simplify the equation above.

1.25c+164.25-2.25c=126.25

3. Simplify even more:

-1c+164.25=126.25

4. Subtract 164.25 from both sides to get:

-1c=-38

5. Divide both sides by -1.

c=38 (this means that there are 38 children)

6. Plug the new value for c back into the equation c+a=73.

38+a=73

7. Subtract 38 from both sides to solve for a:

a=35 (this means that there are 35 adults)

Answer:

25 meals

Step-by-step explanation:

If Rita feeds her dog 2/5 pounds of dog food for each meal, this means;

2/5 pounds = 1 meal

To get the number of meals she will feed if she buys 10 pounds, we will say;

10 pounds = x meals

Divide both equations to get x;

(2/5)/10 = 1/x

Cross multiply;

2/5 x = 10 * 1

2x/5 = 10

2x = 50

x = 50/2

x = 25

Hence the 10pounds food will last 25 meals

The option that negates the given statement is; F: Two segments do not have the same measurement.

In Mathematics, the negation of a statement simply means the opposite of the given mathematical statement. Thus, “X” is a statement, then the negation of statement X is represented by ~X.

Now, we are given the statement;

"Two segments are the same measurement."

Now, for two segments to be the same measurement it means that they are equal and congruent and could possibly measure the same degree, However, it can never mean that they do not have the same measurement.

Thus, the option that negates the given statement is; F: Two segments do not have the same measurement.

Answer:

-62

Step-by-step explanation:

In this question, we are going to solve the given expression.

We know that our f(x) equation is (-7)x - 3

Since we have to find what f(4) is, we would plug in 4 to x and solve.

Solve:

f(4) = -7(4) - 3

= -28 - 3

= -31

We are not done, we have to plug in our answer to the expression f(4 + f(4), since we now know what the value of f(4) is.

-31 - 31

-62

Your answer would be -62.

Coordinates of L after rotation are  (-8,4)

What are the rules of 270 degrees rotation of coordinates about the origin?

Assuming that the rotation is about  (0,0)

then after 270° clockwise rotation (x, y) becomes (-y, x)

and after 270°  anticlockwise rotation (x, y) becomes (y,-x)

Given that LMN with vertices L(4,8), M(4,3) and N(8,8) is rotated  270°  clockwise about the origin

Then for L(4,8) as the rotation is  270°  clockwise then  

(x, y) = (4,8)

and after 270° clockwise rotation (x, y) becomes (-y, x)

Therefore new coordinates of L are (-8,4)

Answer:

-11

Step-by-step explanation:

Answer:

x = 10

y = 5

Step-by-step explanation:

Let the two numbers be x and y

Difference between the two is 10

x-y = 10

Sum;

x+ y is four times the smallest number

Let the smaller number be y

x+ y = 4y

Subtracting equation ii from i

-2y = 10 -4y

4y-2y = 10

2y = 10

y = 10/2

y = 5

Recall;

x-y = 10

x = 10 + y

x = 10 + 5 = 15

Answer:

x = 5.

Step-by-step explanation:

x is the radius of the circle.

The line of length 4 bisects the chord of length 6 into 2 line segments of length 3.

If we draw a line from the centre to where the chord of length 6 meets the circle we have another radius.

This is also the hypotenuse (h) of a right triangle, so we have a right triangle whose legs are 3 and 4, then:

h^2 = 4^2 + 3^2 = 25

h = 5

x = 5 (as x and h are both radii).

The quadrant of P' is (-3 , 2).

Here,

Point P is located at (–3, –2).

Point P is reflected across the x-axis to create P'.

We have to find the quadrant of P'.

What is Reflection across x-axis?

A point after reflection across the x-axis, the x- coordinate remains the same but y - coordinate is taken to be the additive inverse.

Now,

Point P is located at (–3, –2).

Point P is lie on third coordinates.

And, P is reflected across the x-axis to create P'.

Hence, Point P' is lie on second coordinates.

Since, The rule of the reflection across x- axis is,

(x, y) → (x, -y)

Hence, Quadrant of P' = (-3, -(-2)) = (-3, 2)

Therefore, The quadrant of P' is (-3 , 2).
