Estimate each quoitient 2449÷8

Answer:

27

Step-by-step explanation:

If n = 4, all we need to do is substitute the number into the equation.

6n + 3

= 6(4) + 3

= 24 + 3

= 27

Answer:

Para determinar cuantas galletas comió cada integrante de la familia, se debe realizar la siguiente ecuación:

P + M + HMA + HME + YO = 1/2 X

(PR+10) + TIA = 1/4 X

TIO = 1/8 X

Sobran 30 galletas, es decir, 1/8 X

Punto 1)

Si 1/8 X es igual a 30, en el paquete había 240 galletas (30 x 8).

Punto 2)

1- Mamá comió 24 galletas (30 x 4 / 5)

2- Papá comió 24 galletas (30 x 4 / 5)

3- Hermano mayor comió 24 galletas (30 x 4 / 5)

4- Hermano menor comió 24 galletas (30 x 4 / 5)

5- Tía comió 25 galletas ((30 x 2 - 10) / 2)

6- Primo comió 35 galletas ((30 x 2 + 10) / 2)

7- Yo comí 24 galletas (30 x 5 / 5)

8- Quien comió mas galletas fue primo, que comió 35 galletas.

Answer:

B. Memphis is the only city whose highest temperature decreases.

Step-by-step explanation:

Let's analyse each statement looking at the graph given to see how true it is or not:

A. "The initial high temperature in Louisburg is lower than it is in Memphis."

Initial temperature is the y-intercept, that is, it is the point at which the line intercepts the y-axis.

Therefore, the city that has the greatest initial high temperature is Louisburg, which has a blue line labelled l. As you can see, the y-intercept has greater than every other city.

Therefore, Statement A is NOT TRUE.❌

B. "Memphis is the only city whose highest temperature decreases."

The line of Memphis slopes downwards from the left to our right. This shows a decrease in the highest temperature of Memphis. The line of every other city is either horizontal or slopes upwards.

Therefore, Statement B is TRUE.✅

C. "Louisburg always has the highest temperature."

The line of the graph of New Orleans shows that it's highest temperature exceeds that of others. As you can see, the line surpasses that of the rest three. So, Louisburg does not always have the highest temperature.

Therefore, Statement C is NOT TRUE.❌

D. "The high temperature in Phoenix rose faster than the high temperature in New

Orleans."

The slope of the line of New Orleans is more steeper than that of Phoenix. So, New Orleans high temperature rise faster compared to that if Phoenix.

Therefore, statement D is NOT CORRECT.❌

The required algebraic expression that represents the perimeter of the dining room table is 8w - 4.

Perimeter is the measure of the figure on its circumference.

Here,
The perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

Substituting the given expressions for the length and width of the dining room table, we get:

P = 2(3w - 2) + 2w

Simplifying the expression, we get:

P = 6w - 4 + 2w

Combining like terms, we get:

P = 8w - 4

Therefore, the algebraic expression that represents the perimeter of the dining room table is 8w - 4.

Answer:

3

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Since square rooting (√) is the opposite function of squaring a number (exponent of 2), to approximate √10 to the nearest whole number, determine the two squares it is in between.

If you square 3, you will get 9 (3 x 3 = 9) and if you square 4, you will get 16 (4 x 4 = 16). Since 10 is in between 9 and 16, √10 will be in between 3 and 4.

The difference between 9 and 10 is only 1, while the difference between 10 and 16 is 6. Therefore, √10 is closest to 3.

Answer:

y = 2x + 1 ;

y - 3 = - 3(x - 1) ; y = - 3x + 6 ;

Independent ;

(1, 3)

Step-by-step explanation:

Given the data:

Sidewalk 1:

x __ y

2 _ 5

0 _ 1

Sidewalk 2:

x __ y

1 _ 3

3 _ -3

Equation for sidewalk 1 in slope - intercept form:

Slope intercept form:

y = mx + c

c = intercept ; m = slope

m = (change in y / change in x)

m = (1 - 5) / (0 - 2) = - 4 / - 2 = 2

Y intercept ; value of y when x = 0

(0, 1) ; y = 1

Hence, c = 1

y = 2x + 1

Sidewalk 2:

Point slope form:

y - y1 = m(x - x1)

m = slope

m = = (-3 - 3) / (3 - 1) = - 6/2 = - 3

Point (x1, y1) = (1, 3)

y - 3 = - 3(x - 1)

To slope intercept form:

y - 3 = - 3(x - 1)

y - 3 = - 3x + 3

y = - 3x + 3 + 3

y = - 3x + 6

Since the slope of both lines are different, intersection will be at single point and will have a single solution. This makes it independent.

Using substitution method :

y = 2x + 1 - - - (1)

y = - 3x + 6 - - - (2)

Substitute (1) into (2)

2x + 1 = - 3x + 6

2x + 3x = 6 - 1

5x = 5

x = 1

From (1)

y = 2(1) + 1

y = 2 + 1

y = 3

Coordinate of the point of intersection = (1, 3)

thank you kind sir for the help

To calculate the exponential smoothing forecast for May, we need to use the formula Therefore the correct option is A  51.60 .

[tex]Ft = alpha * Xt + (1 - alpha) * Ft-1[/tex]  Where: - Ft is the forecast for time period t - Xt is the actual sales for time period t - Ft-1 is the forecast for the previous time period (t-1) - alpha is the smoothing constant Given that the forecast for January is 50, we can calculate the forecast for February as follows: [tex]F1 = 0.30 * 50 + (1 - 0.30) * 50 = 50[/tex] Similarly, we can calculate

the forecasts for March and April: F2 [tex]= 0.30 * 80 + (1 - 0.30) * 50 = 65[/tex] F3 [tex]= 0.30 * 70 + (1 - 0.30) * 65 = 66.50[/tex] F4 [tex]= 0.30 * 60 + (1 - 0.30) * 66.50 = 63.05[/tex] Now, to calculate the forecast for May: F5 [tex]= 0.30 * Xt-1 + (1 - 0.30) * Ft-1 F5 = 0.30 * 60 + (1 - 0.30) * 63.05 F5 ≈ 51.60[/tex]  Therefore, the forecast for May using exponential smoothing with a smoothing constant of 0.30 is approximately 51.60 (option a).

Hence the correct option is A

You got it right. Triangle DAC

Step-by-step explanation:

Line segment DA is a perpendicular bisector(it cuts line segment CE perfectly in half making line segment AE an CA congruent. Since the triangle share line segment DA that makes them congruent by the SAS postulate

The triangle that is similar to triangle EAD using the Peices of right triangle would be; Triangle DAC

Line segment DA is a perpendicular bisector which cuts line segment CE perfectly in half making line segment AE and CA congruent.

Since the triangle share line segment DA that makes them congruent with the SAS postulate.

Answer:

the number of branches required to use 25 wreaths is 75 branches

Step-by-step explanation:

Given that

The florist used 225 branches of winterberry for making 75 wreaths

First we have to compute the unit rate or the ratio

= 225 ÷ 75

= 3 : 1

Now the number of branches required to use 25 wreaths is

= 3 × 25

= 75 branches

Hence, the number of branches required to use 25 wreaths is 75 branches

Answer:

x=-2, y=-3

Step-by-step explanation:

we can rearrange the questions to make it easier

y=3x+3

2y=-3x-12

if you add the two equations, you get

3y=0x-9

so y=-9/3 = -3

plug y into one of the equations

-3=3x+3

-6=3x

x=-2

and then check your work by plugging into the other equation:

2*-3=-3(-2)-12

-6=6-12
