Answer:

Connie's 5 marbles + Jim's 8 marbles = 13 Total Marbles that Connie now has.

Answer:

Shonda has ( x )dollars in her piggy bank.

Rizzo has ( x-1.50 )

if Shonda has $9 more than x; (x+9),would be equal to

3 times the dollars Rizzo has, or, 3(x-1.50). The two quantities are equal, we can solve for x.

x+9 = 3(x-1.50)

Dustribute the 3

x+9 = 3x - 4.50

Isolate the variable on the left and constants on the right of the equation by subtracting 3x and 9 from both sides.

x+9 = 3x - 4.50

-3x-9 = -3x - 9

-2x = - 13.50

Divide both sides by - 2

Shonda has; x = 6.75

Rizzo has; (6.75 - 1.50) = 5.25

6.75 + 9 = 3(6.75 - 1.50)

15.75 = 3(5.25) or 15.75.

Passes the check.

Shonda has $6.75 in her piggy bank and Rizzo has $5.25.

Answer:

3 hours

Step-by-step explanation:

The difference between the initial temperature and the temperature after an hour is an increase of 5 degrees. Since we need to calculate the time it would take for the temperature to rise to 60 degrees we need to find the difference in degrees from the current temperature to 60 degrees.

60 - 45 = 15 degrees

Since 1 hour equals an increase of 5 degrees we need to divide 15 by 5 to calculate how many hours before the temperature increases to 60 degrees

15 / 5 = 3 hours

It will take 3 hours for the temperature to rise to 60 degrees.

Represent time with x, and the temperature with y.

So, the given parameters can be represented using the following ordered pairs

(x,y) = (0,40) (1, 45), (x,60)

Start by calculating the slope using:

[tex]m = \frac{y_2-y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{45 -40}{1-0}[/tex]

[tex]m = 5[/tex]

Calculate the slope again, using a different set of points.

So, we have:

[tex]m = \frac{60 - 45}{x - 1}[/tex]

This gives

[tex]m = \frac{15}{x}[/tex]

Multiply both sides by x

[tex]mx = 15[/tex]

Divide both sides by m

[tex]x = \frac{15}m[/tex]

Substitute 5 for m

[tex]x = \frac{15}5[/tex]

[tex]x = 3[/tex]

Hence, it will take 3 hours for the temperature to rise to 60 degrees.

Answer:

4 cm on map

Step-by-step explanation:

since 1 cm on map represents 20 km on road, we can either use proportion or ratio to solve this, I'm using direct proportion

  map : road

    1 : 20

    x : 80

20x = 80

    x = 80/20

    x =4

so 80 km on road is 4 cm on map

Answer:

[tex]-12m + 12m =0[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Position = -12m[/tex]

[tex]Rise = 12m[/tex]

Required

Represent as an equation

The new position of the hook is calculated by:

[tex]New\ Position = Initial\ Position + Rise[/tex]

This gives:

[tex]New\ Position = -12m + 12m[/tex]

[tex]New\ Position = 0[/tex]

Hence, the equation is:

[tex]-12m + 12m =0[/tex]

Answer:

third choice : Let 2a + 1 be one odd number, and let 2b + 1 be the other odd number. (2a + 1) + (2b + 1) = 2a + 2b + 2 = 2(a + b + 1). Because 2(a + b + 1) is evenly divisible by 2, it is an even number.

Answer:

The answer is D

Step-by-step explanation:

The measure of the height of the pole (h) will be;

⇒ h = 24 ft.

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The length of the wire which connects the top of a utility pole to a point on the ground = 25 foot

And, A point on the ground located 7 feet away from the base of the pole.

Now,

Let the height of the pole = h

So, We can apply the Pythagoras theorem as;

⇒ 25² = h² + 7²

⇒ 625 = h² + 49

⇒ h² = 625 - 49

⇒ h² = 576

⇒ h = √576

⇒ h = 24 ft.

Thus, The height of the pole = 24 ft.

Answer:

-20 12

Step-by-step explanation:

The new mean of candies = 20 and the standard deviation is 12.

Given that,
Guests at a picnic try to guess the number of candies in a jar.
Mean  = 85,  standard deviation = 12
the jar actually holds 105 candies,
Want to convert each guess to its error, that is, we'll subtract 105 from each guess.

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Since,

Mean  = 85,
jar actually holds 105 candies
New mean = 105 - 85
                = 20
Since,

When a certain value is subtracted from all the values standard deviation still remains the same.,so
Standard deviation = 12

Thus, the new mean of candies = 20, and the standard deviation is 12.

Answer:

the three consecutive even integers are -2, 0, 2

Step-by-step explanation:

Let the first even integer = n

Let the second even integer = n + 2

Let the third even integer = n + 4

From the given statement, we form the equation below

(n²) + (n + 2)²  + 4 = 2(n + 4)²

Expand this equation;

n² + (n + 2)(n + 2) +  4 = 2(n + 4)(n + 4)

n² + n² + 2n + 2n +  4 +  4 = 2(n² + 4n + 4n + 16)

2n² + 4n + 8 = 2(n² + 8n + 16)

2n² + 4n  + 8 = 2n² + 16n + 32

collect like terms together;

2n² - 2n² + 4n - 16n = 32 - 8

- 12n = 24

-n = 24/12

-n = 2

n = -2

Second integer = n + 2

                          = -2 + 2 = 0

Third integer = n + 4

                      = -2 + 4

                      = 2

Therefore, the three consecutive even integers are -2, 0, 2

The three consecutive even integers are -2, 0, 2

Let us assume the first even integer = n

Let us assume the second even integer = n + 2

Let us assume the third even integer = n + 4

Now

[tex](n^2) + (n + 2)^2 + 4 = 2(n + 4)^2\\\\n^2 + (n + 2)(n + 2) + 4 = 2(n + 4)(n + 4)\\\\n^2 + n^2 + 2n + 2n + 4 + 4 = 2(n^2 + 4n + 4n + 16)\\\\2n^2 + 4n + 8 = 2(n^2 + 8n + 16)\\\\2n^2 + 4n + 8 = 2n^2 + 16n + 32\\\\2n^2 - 2n^2 + 4n - 16n = 32 - 8\\\\- 12n = 24[/tex]

n = -2

Now  

Second integer = n + 2

= -2 + 2 = 0

And,  

Third integer = n + 4  

= -2 + 4

= 2
