the 8th grade class planned a trip to kings dominion and 120 students went. Ten students rode with their parents. The rest rode on two charter busses. How many stidents were on each bus

Answer:

49:5

Explanation

Write the quantity of fans in the order of which you are doing the ratio for (TIP - Replace the word "to" with ":") = Football Fans : Hockey Fans = 49:5

The correct ratio of football fans to hockey fans is 49:5 according to the survey results provided, which makes the answer D. 49 to 5.

The survey of sports fans revealed different preferences for various sports. The question asks for the ratio of football fans to hockey fans. According to the survey results provided, 49 people say their favorite sport is football and 5 say it's hockey. Therefore, the ratio of football fans to hockey fans is simply the number of football fans divided by the number of hockey fans.

The calculation would be 49 football fans divided by 5 hockey fans, which simplifies to a ratio of 49:5. Hence, the correct answer is D. 49 to 5. This ratio signifies that for every 5 hockey fans, there are 49 football fans based on the survey results.

Answer: [tex]\angle CAD = 83^\circ [/tex] Option D

Step-by-step explanation:

In this question we use properties of parallelogram and angle sum property of a triangle.

In parallelogram ABCD

[tex] \angle ABC=40^\circ [/tex]

As, we know that opposite angles of parallelogram are equal

Therefore,

[tex] \angle ABC =\angle ADC =40^\circ [/tex]

Now, in triangle ADC

We know that sum of all the angles of a triangle is [tex]=180^\circ[/tex]

[tex]\angle ACD +\angle ADC +\angle DAC =180^\circ[/tex]

[tex]57^\circ +40^\circ +\angle DAC =180^\circ[/tex]

[tex]97^\circ + \angle DAC = 180^\circ [/tex]

Subtracting 97 from both sides we get

[tex] \angle DAC = 180^\circ - 97^\circ [/tex]

[tex] \angle DAC = 83^\circ [/tex]

Measure of [tex]\angle CAD = 83^\circ [/tex]

In a parallelogram, the measure of angle CAD can be found by subtracting the measure of angle ACD from 180°.

In parallelogram ABCD, we have AC as the diagonal. Given that angle ABC is 40° and angle ACD is 57°, we need to find the measure of angle CAD.

In a parallelogram, opposite angles are congruent. So, angle ACD is also equal to 57°.

Now, angle CAD can be found by subtracting angle ACD from 180° (since the sum of the interior angles of a triangle is 180°). So, angle CAD = 180° - 57° = 123°.

x+15.09= -2.57

x= -17.66

If you want the value of x: you would have to subtract -15.09 on both sides.

x+15.09-15.09=-2.57-15.09

x=-17.66

The given number is 32, 897

Here we need to round the thousand place.

Find the number in the thousands place.

We have 2 in the thousands place.

Look for digit which is right to 2.

We have 8, which is greater than 5, if we have the number greater than 5 we have to add 1 with thousands place and make the other numbers zeros.

Since we have 8 right to the number 2, so we add 1 with 2.

2 + 1 = 3

Now thousands place became 3 and make other digits zero.

32, 879 = 33, 000

The answer is 33,000

Note: Here I have attached the place value chart.

It will take approximately 1.25 hours for the snowfall of the two towns to be equal.

To find the number of hours in which the snowfall of the two towns will be equal, we can set up an equation: 3 + 6h = 8 + 2h

where h represents the number of hours.

Simplifying the equation, we get 4h = 5

Dividing both sides by 4, we find h = 5/4 = 1.25 hours.

Therefore, it will take approximately 1.25 hours for the snowfall of the two towns to be equal.

The answer to your problem is -6

b. is the answer if u need to know how just ask me

So,

-2m+5=-2m-5

-2m + 2m = -5 - 5

0 = -10

which is no solution.

Therefore, the required equation is -2m + 5 = -2m - 5.

22. 28 minus(eats) 6 is 22.

He saves $96, The Equation I did for this is 196 Divided by 2

the value of n is 4 because you have to subtract 7n from both sides and then subtract 16 from both sides then the last step is to divide -4 from both sides and you get 4

Answer:

4

Step-by-step explanation:

3n + 16 = 7n is to be solved for n.  Subtract 3n from both sides, obtaining 16 = 4n.

Now divide both sides by 4, obtaining n = 4.

First, find the slope of the line that goes through the 2 given points, which you should know how to do.  Call it m.  Then a perpendicular line must have a slope of -1/m.  The slope-intercept form of the equation you seek is

y = (-1/m)x + b,

where b is any real number.  Examine the list of choices, and pick any that have a slope of -1/m.

The equation that represents the line that passes through the points (2, -6) and (-4,3) is 2y + 3x = -6.

The equation of the line that passes through the points (x1,y1) and (x2,y2) can be obtained with the formula:

[tex]y-y_1 = m (x-x_1)[/tex]

The slope of the points are

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

We need to find the equation that represents the line that passes through the points (2, -6) and (-4,3)

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

[tex]m=\dfrac{3+6}{-4-2}\\\\\\ m = 9/-6 = -3/2\\[/tex]

So, the equation is:

[tex]y-y_1 = m (x-x_1)\\\\y +6 = -3/2(x -2)\\\\2y +12 = -3x +6\\\\2y + 3x = -6[/tex]

Answer: D(2,6)

Step-by-step explanation:

To find  the values of x and y that maximize the objective function

x+y≤8....(line 1)

2x+y≤10.......(line 2)

x≥0......(3)

y≥0.......(4)

we need need to plot them by the following steps.

Step 1: Find coordinates(x,y) of line(1) x+y=8

Put x=0 , we get y =8

Put y=0, we get x=8

by this we got points (0,8) and (8,0) to plot line (1)........(a)

Step 2: Find coordinates (x,y) of line(2) 2x+y=10

Put x=0 , we get y =10

Put y=0, we get 2x=10⇒x=5

by this we got points (0,10) and (5,0) to plot line (2)...........(b)

so with the help of (a) , (b) ,(3) and (4) ,we plot the given graph .

By the graph we can find  that at (x,y)=(2,6) the objective function is maximized , so option D is right.

Answer:

10,12,14

Step-by-step explanation:

Two consecutive integers will have difference of 2.

Let 3 consecutive even integers be a-2, a, a+2

Smallest number = a-2 and middle number = a

Sum of the smallest number and twice the middle number

= a-2+2a =3a-2

20 more than the largest number = 20+a+2 =a+22

i.e. 3a-2 = a+22

2a = 24

Or a =12

Hence three integers even consecutive are 12-2, 12, 12+2

=10,12,14

To find the height of the American flag, convert the known length from yards to feet, use the given ratio to set up a proportion, solve it to find the height in feet, and then convert it back to yards, resulting in a height of 1.2 yards.

The ratio of the length to the height of the American flag is given as 3:2. Knowing that the length of the flag is 1.8 yards, we can set up a proportion to find the height. Since we know that 1 yard equals 3 feet, we first convert the length into feet. 1.8 yards is equivalent to [tex]1.8 imes 3 = 5.4 feet[/tex]. Using the ratio 3:2, we can write the proportion as 3/2 = 5.4/height in feet. To solve for the height, we cross-multiply and [tex]get 2 imes 5.4 = 3 imes height,[/tex] yielding 10.8 = 3  imes height. Dividing both sides by 3 gives us the height as 3.6 feet. To convert feet back to yards, we recall that 3 feet equal 1 yard, and hence, 3.6 feet is 1.2 yards. Therefore, the height of the American flag is 1.2 yards.
