Answer:

463.49

Step-by-step explanation:

400: four hundred

60: sixty

3: three

.49: forty nine hundredths

400 + 60 + 3 + .49 = 463.49

Answer:

None are correct.

Step-by-step explanation:

10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.

15/30 wanted cheese, so 1/2 wanted cheese.

5/30 wanted hamburgers, so 1/6 wanted hamburgers.

You can use this information to estimate the number of the 150 students who wanted each.

1/3 of 150 = an estimated 50 wants pepperoni

1/2 of 150 = an estimated 75 wants cheese

1/6 of 150 = an estimated 25 wants hamburgers

Now you can use this to see which one is true.

A. There are 40 students who want pepperoni

not true, there are 50

B. There are 100 students who want either pepperoni or hamburger

50(pepperoni) + 25(hamburger) = 75, so this is not true

C. There are 10 more students who will want cheese than hamburger

75(cheese) - 25 (hamburger) = 50, so this is not true.

D. There are 5 more students would want pepperoni than hamburger

50 (pepperoni) - 25 (hamburger) = 25, so this is not true

None of these answers are correct

Answer:

(-4,-1)

Step-by-step explanation:

-3x+10y=2

-3x+3y=9

-3x=2-10y

-3x=9-3y

2-10y=9-3y

2-9=10y-3y

7y=-7

y=-1

-3x+3(-1)=9

-3x-3=9

-3x=12

x=-4

Answer:

X=4, y=-1

Step-by-step explanation:

-3x+10y=2 multiple by 3

-3x+3y=9 multiply by 10

9x+30y=6

30x+30y=90

Subtract equation 1 from 2

30x-9x+30y-30y=90-6

21x+0=84

21x=84

Divide both side by 21

X=4

Substitute 4 for x in equation 1

3x+10y=2

3(4)+10y=2

12+10y=2

10y=2-12

10y=-10

Divide both side by 10

Y=-1

2. [tex]\displaystyle 64\:feet[/tex]

1. [tex]\displaystyle 5\:seconds[/tex]

Step-by-step explanation:

2. Sinse we do not have a y-intercept [C-value in this case], we have to use a part of the quadratic formula to solve for x, and rewrite this equation in Vertex Form, with [tex]\displaystyle [h, k][/tex] as the vertex point. Observe:

[tex]\displaystyle -\frac{b}{2a} = x \\ \\ -\frac{64}{2[-16]} = \frac{-64}{-32} = 2[/tex]

Now, keep in mind that [tex]\displaystyle -h[/tex] in the vertex formula, [tex]\displaystyle y = a[x - h]^2 + k,[/tex] gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so in this case, sinse 2 is already positive, you do not need to alter its operation sign. With this being stated, you should already have this:

[tex]\displaystyle y = -16[x - 2]^2[/tex]

Now, to find k, all you have to do is plug 2 into the TOP equation to get your maximum height:

[tex]\displaystyle -16[2]^2 + 64[2] = -16[4] + 128 = -64 + 128 = 64 \\ \\ \\ y = -16[x - 2]^2 + 64[/tex]

Therefore, sinse 64 is your k-value, 64 feet is indeed your maximum height.

1. Simply factour the quadratic equation:

[tex]\displaystyle y = -18x^2 + 90x \\ 0 = -18x[x - 5] \\ \\ 5, 0 = x[/tex]

In this case, from a height of sixty-four feet, it is IMPOSSIBLE for the football to hit the ground in zero seconds, therefore the ball will reach the ground in 5 seconds, which makes alot more sence.

I am joyous to assist you at any time.

Answer:

Sample space S = {0,1,2,3,4,5}

Step-by-step explanation:

We all know that when a dice is tossed, the minimum value that can be obtained is 1 and the maximum value that can be obtained is 6.

Now, when two dice are tossed, the possible cases are:

[tex]= \left\{\begin{array}{cccccc}(1,1)&(1,2)&(1,3) &(1,4)&(1,5)&(1,6)\\(2,1)&(2,2)&(2,3) &(2,4)&(2,5)&(2,6)\\(3,1)&(3,2)&(3,3) &(3,4)&(3,5)&(3,6)\\(4,1)&(4,2)&(4,3) &(4,4)&(4,5)&(4,6)\\(5,1)&(5,2)&(5,3) &(5,4)&(5,5)&(5,6)\\(6,1)&(6,2)&(6,3) &(6,4)&(6,5)&(6,6)\end{array}\right\}[/tex]

However, the magnitude of the difference in no. of dots showing up in the two dice is:

[tex]= = \left\{\begin{array}{cccccc}(1,1)=0&(1,2)=1&(1,3)=2 &(1,4)=3&(1,5)=4&(1,6)=5\\(2,1)=1&(2,2)=0&(2,3)=1 &(2,4)=2&(2,5)=3&(2,6)=4\\(3,1)=2&(3,2)=1&(3,3)=0 &(3,4)=1&(3,5)=2&(3,6)=3\\(4,1)=3&(4,2)=2&(4,3)=1 &(4,4)=0&(4,5)=1&(4,6)=2\\(5,1)=4&(5,2)=3&(5,3)=2 &(5,4)=1&(5,5)=0&(5,6)=1\\(6,1)=5&(6,2)=4&(6,3)=3 &(6,4)=2&(6,5)=4&(6,6)=0\end{array}\right\}[/tex]

Thus, the sample space Sample space-related when two dice are tossed & the magnitude is:

Answer:

63 inches

Step-by-step explanation:

the diameter is the entire line across the circle, the things needed to find out the circumference of the circle are the radius. that means you would divide your diameter in half to get 10. after you done that, you would input that into the equation:

c=2Π10

that would get you about 62.83 or 63

Answer:

100.3 units²

Step-by-step explanation:

Area of the figure = area of two semicircles + area of a parallelogram

= 2(½*πr²) + b*h

Where,

Radius (r) = ½ of 8 = 4

Base (b) = 10

Height (h) = 5

Plug in the values

Area of figure = 2(½*π*4²) + 10*5

= 16π + 50

Area = 100.265482

Area of figure = 100.3 units² (nearest tenth)

Answer:

to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.

Step-by-step explanation:

For example..

If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

Answer:

1/2 x b x h

Step-by-step explanation:

b= base

h= hieght

1.  Multiply your base by 1/2

2. Then multiply the sum of that by your hieght

Ex: A trianle with a base of 18 and hieght of 4

1. 1/2 x 18 = 9

2. 9 x 4 = 36
