Solving Quadratic Equations-factoring
How do find what b could be? My book says to factor completely.
3b²+15b+12=0

Answers

Answer 1

Answer:

b  =  −1

b  =  −4

Step-by-step explanation:

Common Factor

Divide both sides of the equation by the same term

Use the quadratic formula

Answer 2

Answer:

-1 or -4

Step-by-step explanation:

first all you have to do is to multiply 12 by 3b² to give you 36b² and then find a number(x) multiplied by another number(y) to give you 36b² and those two numbers must sum up to give you 15b

doing this, we would have our two numbers to be

12b and 3b

replace these two numbers with 15b in the equation

3b² + 12b + 3b + 12=0

(3b²+12b) + (3b+12)=0

3b(b+4)+3(b+4)=0

note: the numbers in the brackets must be the same

(3b+3)(b+4)=0

therefore, 3b + 3= 0 or b + 4= 0

3b+3= 0

3b=-3

b=-3/3

b=-1

or

b+4=0

b=-4

If a student likes hotdogs, what is the probability that student also likes burgers?
93.8%

Answers

Answer:

like burgers with the wrong total of 76/150 is 50.7%

do not like burgers with also the wrong total of 74/150 is 50% simplified

now with the right totals its 54% for liking burgers and 46% for not liking

Step-by-step explanation: 32 + 49 + 81 = 162

                                           44 + 25 + 69 = 138

right total (162) wrong total (76)

right total (138) wrong total (74)

right (300) wrong (150)

unless u simplified by 2 which is 150/300 then its right simplified

so im confused but this is my answer

Answer:

Years late but I'll answer anyway. It is C. 42.1%

Step-by-step explanation:

A two-way table is a bivariate table. Bivariate tables have rows and columns just as your table has.

Remember, a column is vertical and a row is horizontal. Each value in the data table is called a cell.

In this case, you have to do column relative frequency. This is a cell frequency divided by the column total. It's not as hard as it may sound.

The number of people who like hotdogs and burgers is 32, and the total for that column is 76. All you have to do is divide 32 by 76 and you have your answer.

32 / 76 = 0.421 or 42.1%

Hello! Answer: 116.64

Step-by-step explanation:

What I did was multiplied 5.4 by 7.2 by 6 and we get a total of 233.28 then we just divide by 2 so...

233.28 ÷ 2 = 116.64 HOPE THAT HELPS!

Answer:

Step-by-step explanation:

To find the volume of a three dimensional shape, you can multiply all three dimensions(length, width, and height).

Volume = 5.4 * 7.2 * 6

Volume = 233.28

If you round to the nearest tenth place, your answer is 233.28 inches cubed . However, if you think about a triangle, the area is base times height divided by two. Similarly, you have to divide the volume by two to get your final answer. Thus, your final answer is (C) 116.64

Help question is in the pic PLEASE EXPLAIN HOW YOU GOT THE ANSWER!

Answers

Part A

The rectangular prism is a box, and the volume of the box is

V = L*W*H

so we simply multiply the length (L), width (W) and height (H)

In this case, the dimensions of the box are

L = 13W = 5H = 6

The order doesn't matter in this case because we can multiply two or more numbers in any order we want (eg: 6*7 = 7*6 = 42)

So,

V = L*W*H

V = 13*5*6

V = 390

The volume of one box is 390 cubic inches.

I'm not sure what formula Diego is using. It seems like he's computing the perimeter of the base (the 13 inch by 5 inch rectangle) to get 13+5+13+5 = 36 inches. Then he's multiplying that by 6 to get 36*6 = 216; however, this value is meaningless because we won't involve the perimeter at all when it comes to finding the volume.

--------------

So in short, Diego is incorrect. All Diego needs to do is multiply the three values 13, 5 and 6 to get the volume of one box to be 390 cubic inches.

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

Part B

Use the same formula back in part A. That formula being V = L*W*H.

We'll use this formula to compute the volume of each carton.

Carton A has a volume of 10*13*28 = 3640 cubic inchesCarton B has a volume of 10*14*22 = 3080 cubic inchesCarton C has a volume of 11*12*26 = 3432 cubic inches

All three cartons have a volume larger than 390 cubic inches, meaning that we can fit at least one box.

If one box is 390 cubic inches, then 8 of them lead to a volume of 8*390 = 3120 cubic inches. Note that this value (3120) is larger than the volume of carton B. There's no way that Diego can use carton B to hold all 8 boxes at once. So we have no choice but to rule it out.

Carton C on the other hand has a volume of 3432 cubic inches, which is larger than the 3120 figure we got. Meaning he can house all 8 boxes here. The amount of leftover space is 3432-3120 = 312 cubic inches which is what the packing material will take care of. In other words, you need 313 cubic inches of packing material for carton C. Carton A is a similar story, but will require more packing material (since carton A's volume is larger).

The best option is to go with carton C. It allows him to hold all the 8 boxes, with the least amount of packing material required.

What is the volume of the figure composed of two congruent triangular prisms if a = 4 units, b = 2 units, and c = 6 units?

Write your answer as cubic units, e.g. 20 cubic units

Answers

Volume is area of the base times the height, so if a is 4, and b is 2 then the area of the triangle is (4x2) divided by 2, which is 4 square units. Now you have the area of the base, so you need to multiply it by the height, which is 6. 4 times 6 is 24 cubic units.
ANSWER: 24 cubic units

The volume of the figure composed of two congruent triangular prisms is 48 cubic unit.

What is Volume?

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Cubic units are used to quantify a solid's volume. For instance, the volume will be given in cubic metres if the dimensions are given in metres.

We have, a= 4 unit, b= 2 unit and c= 6 units

So, the Volume of Triangular prism

= 1/2 x b x h x l

= 1/2 x 4 x 2 x 6

= 4 x 6

= 24 cubic unit

Thus, the required volume is

= 24 x 2

= 48 cubic unit

One side of the triangle is 4 cm, and the sum of the other two sides is equal to a
whole number of cm. What is the smallest possible perimeter of the triangle?
A. 9 cm
B. 10 cm
C. 11 cm
D. 15 cm
E. 17 cm

Answers

Answer:

A) 9 cm

Step-by-step explanation:

By the Triangle Inequality, any two sides of a triangle must be greater than the remaining side.

In order to minimize the perimeter, we will assume that 4 cm is the longest side.

Thus, the two remaining sides must be greater than 4.

Since we are given that the sum of the two remaining sides is a whole number, the smallest whole number value greater than 4 is 5.

Hence, the smallest perimeter possible 9 cm.

Our answer is A.

A 9cm is the answer of this problem

In a right triangle, apart from the right angle, the other two angles are

x + 1 and 2x + 5. find the angles of the triangle.

Answers

Answer:

The two other angles are 29 degrees and 61 degrees

Step-by-step explanation:

There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.

180 - 90 = 90

If x equals 28

28 + 1 = 29

2 x 28 + 5 = 61

29 + 61 = 90

The two other angles are 29 degrees and 61 degrees

Answer:

29 , 61

Step-by-step explanation:

Sum of all angles of a triangle = 180

90 + x + 1 +2x +5 = 180 {Combine like terms}

96 + 3x = 180         {Subtract 96 from both sides}

         3x = 180 - 96

          3x = 84 {Divide both sides by 3}

           x = 84/3

x = 28

x +1 = 28 +1 = 29

2x +5 = 2*28 + 5 = 56 + 5 = 61

Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Answer:

x = 17 cm

Step-by-step explanation:

Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem.  (a² + b² = c²)

First, plug the values into the equation:  (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)  

8² + 15² = c²

Square 8 and 15( or multiply them by themselves):

64 + 225 = c²

Add:  

289 = c²

Take the square root of both sides:  

√289 = √c²

Simplify:

17 = c

Therefore, x = 17 cm.
