Answer:

Step-by-step explanation:

Remark

This question is a little ambiguous. You might not be sure how to treat the Chiefs. Include their 10 or not. Turns out you do.

So the total score was 45

But this can be solved without using that information. The key is that the total number of plays made was 13

Givens

Let the touchdowns = x

Let the point after = y

Let the field goals = z

The number of point afters = the touchdowns. x = y

The number of touchdowns is 6 times the field goals: z = x / 6

Equation.

x + y + z = 13            Substitute x for y

Solution

x + x  + z = 13          Combine the left: substitute x/6 for z

2x    + x/6 = 13        Multiply by 6 to get rid of the fraction

6*2x + x = 13 * 6      Combine the left

12x + x = 13*6          Combine the left

13x = 13 * 6              Divide by 13 on both sides.

13x/13 = 6

x = 6

====================

Answer

x = 6

y = 6

z = 1

Check

It's time to see what happened.

6 touchdowns = 6 * 6 = 36

6 single points = 6 * 1 =  6

1 field goal      <u>            =   3   </u>

Total                              45

Apparently we got the right answer. You made one small error in the last equation. z should equal x/6

Very interesting problem. Sports stat guys are going to love this question. Thanks for posting.

3) 24

4) 72


<u>Explanation</u>

Q1

The surface area of a cone is given by;

S.A = 2Πrl + Πr²

Where r is the radius of the base and l is the lateral height.

Πr² = area of the base = 20 in²

2Πrl = Area of the lateral surface

         = 2.5 × 20

          = 50

Area of the cone = 50 + 20

                            = 70 in²

Q2

The sides of the Pythagorean triangle with legs of 12 and 16.

The 3rd side will be;

c = √(12² + 16²)

  = √400 = 20

Volume = 12 × 16 × 20

              = 3,840

Q3

The volume of a cone is given by;

volume = 1/3 Π r² h

This shows that the volume of a cone is a third the volume of the cylinder.

∴ Volume of the cylinder = 12 × 3

                                            = 24 ft³

Q4

The volume of any regular figure is;

Volume = base area × height

When the dimensions area usually 3. Let these dimensions be x, y and z.

∴ volume  = x × y × z = 9

  Doubling the dimensions;

Volume = 2x × 2y × 2z = 2 × 2 × 2 × 9

             = 8 × xyz = 8 × 9

             = 72 ft²

12x + 4 divided by 4 plus 20x + 5 divided by 5
Rasek [7]
12x + 4 ➗ 4 + 20x + 5 ➗ 5

1. PEMDAS (order of operations) solve the division problems

(4 divided by 4 & 5 divided by 5)
12x + 1 + 20x + 1

2. Swap around the order of operations as commutative property states that you can swap the order of an addition problem and get the same answer.

12x + 20x + 1 + 1

3. Add like terms

32x + 2

This is the most simplified answer you could get as you can not add 32x and 2 as they are not like terms.

What is 1/4 (5y-3)+1/16 (12y+17
netineya [11]

What is the question? If you are only trying to expand the expression then the answer would be:

1/4 (5y-3)+ 1/16 (12y+17)

(5y/4) – (3/4) + (12y/16) + (17/16)

1.25y – 0.75 + 0.75y + 1.0625

2y + 0.3125

 

If you are trying to find for y, then you forgot to equate it to 0, that is:

2y + 0.3125 = 0

2y = -0.3125

<span>y = 0.15625</span>

Two dice are rolled, and the sum of the face values is six. What is the probability that at least one of the dice came up a thre
gizmo_the_mogwai [7]

Answer : P(\text{ atleast one of the dice come up 3})= \frac{1}{5}

Explanation :

We know that ,

Sample space of " sum of faces is 6"= \{(3,3),(4,2),(2,4),(5,1),(1,5)\}

Atleast one of the dice come up 3 = \{(3,3)\}

So,

Probability = \frac{\text{No. of favourable outcomes}}{\text{Total no. of outcomes}}

P(\text{ atleast one of the dice come up 3})= \frac{1}{5}
