Answer 1

Answer:

J'(3 , 5)

Step-by-step explanation:

Rule for reflection over x-axis,

Original point(x , y)  After reflection (x, -y)

After reflection, there will be no change in the x-coordinate and y - coordinate will the change the sign

So, J(3,-5)    After reflection J'(3,5)

The fitness center held a weight loss competition in which 128 people participated. The amount of weight loss was normally distributed with a mean of 18 pounds and a standard deviation of 5.4 pounds. Approximately how many people lost at least 15 pounds?

Answers

Answer:

37

Step-by-step explanation:

Given :

Sample size, n = 128

Mean, μ = 18

Standard deviation, σ = 5.4

Number of people who lost atleast 15 pounds :

The Zscore = (x - μ) / (σ)

Zscore = (15 - 18) / 5.4

Zscore = - 3 / 5.4

Zscore = - 0.5555

P(Z < - 0.555) = 0.28945

Number of people who lost atleast 15 pounds :

0.28945 * 128 = 37.0496

= 37 people

What is the solution to the linear equation?

d – 10 – 2d + 7 = 8 + d – 10 – 3d

(need answer asap)

Answers

Answer:

-10 -2d+7=8-10-3d

-2d + 7 =8 -3d

-2d + 7 =3d = 8

-2d + 3d = 8-7

d=8-7

d=1

Answer:

[tex]d = 1[/tex]

Step-by-step explanation:

Step 1:  Combine like terms

[tex]d - 10 - 2d + 7 = 8 + d - 10 - 3d[/tex]

[tex](d - 2d) + (-10 + 7) = (8 - 10) + (d - 3d)[/tex]

[tex](-d) + (-3) = (-2) + (-2d)[/tex]

Step 2:  Add 2d to both sides

[tex]-d + 2d - 3 = -2 - 2d + 2d[/tex]

[tex]d - 3 = -2[/tex]

Step 3:  Add 3 to both sides

[tex]d - 3 + 3 = -2 + 3[/tex]

[tex]d = 1[/tex]

Answer:  [tex]d = 1[/tex]

the sum of two positive consecutive integers is x. in terms of x, what is the value of the smaller of these two integers?​

Answers

Answer:

In terms of x, the smaller integer is (x - 1)/2

Step-by-step explanation:

Two consecutive positive integers can be written as:

n and (n + 1)

Where n is an integer and:

n > 0.

notice that the smaller of the two integers is n.

We know that the sum of these two integers is equal to x, then:

n + (n + 1) = x

we can rewrite this as:

2n + 1 = x

solving this for n (the smaller of the two integers) we get:

2n = x - 1

n = (x - 1)/2

In terms of x, the smaller integer is (x - 1)/2

- 2 / 7

Step-by-step explanation:

Let,

x2 = 14

y1 = 2

y2 = 0

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope

= ( 0 - 2 ) / ( 14 - 7 )

= - 2 / 7

[tex]slope \\ = \frac{Δy}{Δx} \\ = \frac{(4 - 2)}{(0 - 7)} \\ = \frac{2}{ - 7} \\ \\ so \: the \: slope \: is \: \frac{2}{ - 7}.[/tex]

choose 1 answer
the same line
distinct parallel lines
Perpendicular lines
intersecting, but not perpendicular lines

Answers

Answer:

The same lines (answer)

Step-by-step explanation:

The equations can be written in slope-intercept form y = mx + c (where 'm' is slope and 'c' is the y-intecept) as,

y-3 = 2(x-3) .......(1)        ;   y + 5 = 2(x+1) ...........(2)    

y = 2x - 6 + 3                ;  y = 2x + 2 - 5    

y = 2x -3                       ;  y = 2x - 3

Comparing with slope intercept form we have,

m1 = 2                           ; m2 = 2

c1 = -3                           ; c2 = -3

If the slopes are equal the lines are parallel and since y-intercepts are also equal means they are the same lines (overlapping)

Manuel y Sara recorren cierta distancia, y los tiempos que emplean están en la razón 21 / 15 . La velocidad de Manuel es de 56km/h. ¿Cuál es la velocidad de Sara?

Answers

Answer:

The speed of Sara is 78.4 km/h.

Step- by-step explanation:

Manuel and Sara travel a certain distance, and the times they use are in the ratio 21/15. Manuel's speed is 56km / h. What is Sara's speed?

Let the distance is d.

speed of Manuel = 56 km/h

time taken by Manuel = 21 t

time taken by Sara =  15 t

Let the speed of Sara is v.

Distance = speed x time

For Manuel:

d = 56 x 21 t ..... (1)

For Sara:

d = v x 15 t ..... (2)

From (1) and (2)

56 x 21 t = v x 15 t

v = 78.4 km/h

What is the circumference os the circle shown below? (Round your answer to the nearest tenth.)​

Answers

Answer:

Option C(66.0)

Step-by-step explanation:

C = 2πr

C=Circumference

π=3.14(pi)

r=radius

C=2x3.14x10.5

3.14x10.5=32.97

32.97x2=65.94

65.94 rounded to nearest tenth is 65.9, so basically 66.0.

 

Answer: C. 66.0


Step 1: Write an equation

To start off, we will need to write an equation. Before we solve, let’s write the formula for a circumference.

C= 2πr

Step 2: Substitute numbers

Now that we have the equation, we need to substitute the information shown in the shape. Let’s substitute r in the equation with 10.5. We will do this because this is the radius of the circle. We will not be using 14.8 since it does not go to the center of the circle. Let’s replace r now.

C= 2πr
C= 2π10.5

Step 3: Solve

Let’s solve for the circumference using the equation we have created. To make it easier, we will add a multiplication sign in between each number before we solve.

C= 2π10.5
C= 2 × π × 10.5
C≈ 65.97

The circumference is approximately 65.97. Since we are asked to round to the nearest tenth, the circumference will need to be rounded up. Let’s do this now.

C≈ 65.97
C≈ 66.0

This is your answer. Hope this helps! Comment below for more questions.

When the length of each side of a square is increased by 5 cm, its area is increased by 895 cm2. Find the length of a side before the increase.

The length of a side before the increase is...

Answers

Answer:

Step-by-step explanation:

Increasing the side length by 5 is represented as s + 5. To get the area of a square we multiply side times side: [tex](s+5)^2=s^2+10s+25[/tex]

The area of a square is s². If we are increasing this area s² by 895, then to represent this we have s² + 895.

Put that together into an equation:

[tex]s^2+10s+25=s^2+895[/tex] and simplify to

10s = 870 so

s = 87

Let's check that. The area before the addition to the side is 87*87 = 7569; the area after the addition of 5 cm is 92*92 = 8464. The difference is

8464 - 7569 = 895 so we did good!

Charlotte volunteered to deliver dinners for seniors. The supervisor told her to take half the meals to Oak Hill Senior Center, one-fourth of them to the Glenview Apartment complex, and one-fifth of them to North-side neighborhood center. Unfortunately, there were 19 meals, which didn’t divide evenly as mandated. How could Charlotte follow the supervisor’s instructions without splitting apart any meals?

Answers

Answer:

Charlotte should take 5 meals to Glenview Apartment complex, 4 meals to North-side neighborhood center and 10 meals to Oak Hill Senior Center

Step-by-step explanation:

The given number of meals = 19 meals

The fraction of the meals to be taken to Oak Hill = (1/2)

The fraction of the meals to be taken to Glenview Apartment = (1/4)

The fraction of the meals to be taken to North-side neighborhood = (1/5)

Let A represent an even number of meals, we have;

The total meals she delivers = (1/2)·A + (1/4)·A + (1/5)·A = (19/20)·A

The remaining meals = A - (19/20)·A = (1/20)·A

Therefore, if the meals where 20, she would have an excess of 1 meal left

Therefore, the number of meals she can share using the given fractions = 19 meals

Therefore;

The number of whole meals she can take to Glenview = 20×(1/4) meals = 5 meals

The number of whole meals she can take to North-side neighborhood = 20 × (1/5) meals = 4 meals

Therefore, the number of meals she would take to Oak Hill Senior Center = (20 - 5 - 4) meals = 10 meals
